Definitions

  • This application is directed to systems, methods, and computer program products of a transport layer and transport model.
  • the transport layer and transport model are particularly well adapted to the Automated Meter Infrastructure (AMI) and Automated Meter Reading (AMR) environments.
  • AMI Automated Meter Infrastructure
  • AMR Automated Meter Reading
  • a mesh network is a wireless network configured to route data between nodes within the network. It allows for continuous connections and reconfigurations around broken or blocked paths by retransmitting messages from node to node until a destination is reached.
  • Mesh networks differ from other networks in that the component parts can all connect to each other via multiple hops. Thus, mesh networks are self-healing: the network remains operational when a node or a connection fails.
  • AMI, AMR, or Advanced Metering Management (AMM) technologies include systems that measure, collect and analyze utility usage, from advanced devices such as electricity meters, gas meters, and water meters, through a network on request or a pre-defined schedule.
  • This infrastructure includes hardware, software, communications, customer-associated systems and meter data management software. The infrastructure collects and distributes information to customers, suppliers, utility companies and service providers. This enables these businesses to either participate in, or provide, demand response solutions, products and services. Customers may alter energy usage patterns from normal consumption patterns in response to demand pricing. This improves system load and reliability.
  • Mesh networks may include at least one mesh gate and at least one mesh device, such as a meter.
  • the mesh gate may communicate with the meters over a mesh network.
  • the mesh gate may also communicate with a server over a wide area network.
  • the mesh gate may form a mesh network with nearby meters and interface between the meters and the server.
  • OSI Reference Model provides a layered, abstract description for communications and computer network protocol design, developed as part of the Open Systems Interconnection (OSI) initiative. It is also called the OSI seven layer model.
  • the layers are conventionally, from top to bottom, Application, Presentation, Session, Transport, Network, Data Link, and Physical.
  • a layer is a collection of related functions that provides services to the layer above it and receives service from the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of the path.
  • the typical or conventional Transport layer (layer 4) under the OSI model provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers.
  • the transport layer may typically control the reliability of a given link through flow control, segmentation and/or de-segmentation, and error control.
  • TCP Transmission Control Protocol
  • OSI protocols Of the actual OSI protocols, not merely protocols developed under the model, there have heretofore generally considered to be five classes of transport protocols, ranging from class 0 (which is also known as TP0 and provides the least error recovery) to class 4 (which is also known as TP4 and is designed for less reliable networks, similar to the Internet). Class 4 is closest to TCP, although TCP contains functions, such as the graceful close, which OSI assigns to the Session Layer.
  • the conventional or typical Network layer (Layer 3) under the OSI model provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks while maintaining the quality of service requested by the Transport layer.
  • the Network layer performs network routing functions, and might also perform fragmentation and reassembly, and report delivery errors.
  • IP Internet Protocol
  • the technology includes networks, network devices, and computer program products for implementing a transport layer.
  • Each embodiment has a transport layer module operable to provide connection oriented transport layer services to an application layer, a presentation layer, and a session layer.
  • the transport layer header flags essentially consist of: SYN, ACK, PSH, and RST.
  • a connection is terminated only by a computer program product operating on a network device sending or receiving a message with the RST flag set, or by a timeout.
  • data can be transferred in a message from a receiving node containing the first set ACK flag of a connection.
  • sequence numbers are assigned only at the packet level.
  • the packet level is the minimum level of data segmentation.
  • a transport layer implemented by the transport layer module directly interfaces with a data link layer without the presence of a separate network layer.
  • FIG. 1 illustrates an embodiment of the TIP protocol shown in the context of related AMI protocols.
  • FIG. 2 illustrates an AMI packet including a TIP header of the present technology.
  • FIG. 3 is a state diagram of the present technology illustrating how connections can be established and closed.
  • FIG. 4 illustrates TIP aspects of a simple communication between nodes of the present technology.
  • FIG. 5 illustrates communication between two nodes where a first node sends a message indicating the beginning of a segmented request (e.g., no PSH flag set), but a second node does not support segmented requests.

  • FIG. 12 illustrates a coordinator of the present technology facilitating communication between an IP node of an IP network sending a TCP-formatted message to a TIP node of a mesh network.
  • the present transport layer technology enables reliable transmission of large messages.
  • the technology provides end-to-end acknowledgement of messages, rejection of duplicate packets, multi-packet messaging, and port multiplexing within a network node.
  • the TIP protocol 100 is shown in the context of related AMI protocols.
  • a simplified protocol stack used for direct communication during installation, maintenance, and walk-by of an AMI node is shown in the middle column 130 .
  • TIP implements functions similar to IP and TCP in a single layer.
  • IP functionality TIP uses a smaller transmission unit, e.g., a single IEEE 802.15.4 packet. Version control, priority, flow label, payload length, next header, and hop limit as used in IP are not transported. Source address and destination address are only sometimes transported, as will be described in more detail below. Option headers are not used.
  • TIP employs packet-level sequence numbers instead of byte-level sequence numbers—in protocol stacks employing TIP it is not allowed for an intermediate node to re-fragment a packet, hence the TCP byte-level sequence number is not required.
  • TIP presents a single packet window. This approach is possible, in part, because some target networks employing TIP in the protocol stack, e.g., AMI networks, present homogeneous, half duplex, low latency characteristics. TIP is less complex than TCP to implement, requires less resources, and removes the need to include the window size in the header.
  • Termination of a connection is through one message, i.e., RST, rather than through three, i.e., FIN, ACK, and then ACK. Further, offset and checksum are not transported; fixed timeouts are used; and the URG flag and urgent pointer are not supported.
  • An early open feature representing the ability to piggyback payload data during a three-way connection handshake, is provided.
  • TIP introduces an overhead of 21 bytes for communication between an AMI node and an IPv6 node on the first packet of a communication, and only a 4-byte overhead on subsequent packets.
  • TCP/IPv6 packets which introduce an overhead of at least 64 bytes on all packets
  • TIP introduces an overhead of 21 bytes for communication between an AMI node and an IPv6 node on the first packet of a communication, and only a 4-byte overhead on subsequent packets.
  • both the first and all subsequent packets are burdened with only a 4-byte overhead.
  • an AMI packet 200 including a TIP header 210 of the present technology is shown.
  • the packet 200 includes: an IEEE 802.15.8 Media Access Control (MAC) header 220 ; a mesh network header 230 ; a header for layers above the transport layer in conventional protocols, shown as an Application Header 240 ; and a packet payload 250 .
  • MAC Media Access Control
  • the mesh network header 230 is not used for direct communication during installation, maintenance, and walk-by of an AMI node.
  • the TIP header 210 includes an eight-bit flag field 212 .
  • the flag field 212 uses bits 5 - 7 (three bits) to indicate extension type. For example, in bits 5 , 6 , and 7 , binary values 000 and 001 can be reserved to avoid conflicts with extended mesh network service; binary values 010, 011, and 111 also can be reserved; binary value 100 indicates intra-TIP communication; binary value 101 can indicate IPv4 communication with TIP; and binary value 110 can indicate IPv6 communication with TIP.
  • Bit 4 is a flag for acknowledgment (ACK); bit 3 is a flag for the push message (PSH); bit 2 is a flag for the reset message (RST); bit 1 is a flag for synchronization (SYN). Finally bit 0 is reserved.
  • the TIP headers include an eight-bit sequence number 214 pre-incremented for each transmitted packet, excluding acknowledgement messages and retries.
  • the TIP header also contains the value of the last packet sequence number received by the sender of the current packet.
  • TIP allows port addressing within a node.
  • ports 0 - 2 are inbound ports used for regular reporting, high priority reporting, and on-demand ANSI C12.22 respectively; ports 3 and 4 are reserved; ports 5 - 14 are outbound ports with 5 - 9 used for ASNI C12.22 relaying to WAN to LAN NATing and ports 10 - 14 used for internal processes such as mass upgrade and mass configuration of network nodes.
  • port 0 is reserved; port 1 is an outbound port for ASNI C12.22 reporting; port 2 is an inbound port for on-demand ANSI C12.22; ports 3 - 14 are reserved; and port 15 is an inbound RFD proxy port.
  • the TIP header further contains an extension field 218 defined by the extension type bits, e.g., bits 5 - 7 of the flag field 212 , e.g., as one of intra-TIP, IPv4/TIP, and IPv6/TIP.
  • extension type is set to intra-TIP
  • the extension field 218 is formatted as an eight-bit field where bits 5 - 7 indicates a source port number; while bits 0 - 3 indicate a destination port number.
  • the extension field is a seven-byte (56-bit) field using 32 bits for the IP address of the node on IPv4 network, 16 bits for the port number at the IPv4 address, and 8 bits for the port number of the TIP network address (though in some embodiments, less than 8 bits may be used).
  • the extension field uses 128 bits for the IPv6 address, 16 bits for the port address at the IPv6 address, and the last 4 bits of the final byte for the port number of the TIP network address.
  • Implementations of the technology turn the relatively unreliable and very basic services provided by a data link layer into a more powerful technology for AMI communications through the use of a connection-oriented approach that provides same-order delivery, improved data reliability through retransmission of packets, flow control, streaming, and port addressing.
  • connection establishment a communication is started between a source and a target (potential destination) by the exchange of packets with the SYN flag set.
  • the initial “packet sequence number” is set to an arbitrary value from a range of valid sequence numbers to mitigate the risk of false duplicate packet detection.
  • the “packet sequence number” returned is also set to a separate arbitrary value from the range.
  • the “last received sequence number” returned from the destination is set to the “packet sequence number” received last by that node.
  • the first packet is accepted by the target unless duplicated.
  • the first packet is considered duplicated if received before the timeout, e.g., eight (8) seconds, with the same “packet sequence number” and CRC. Only packets received with the SYN flag set and a matching “last received sequence number” are processed as a connection establishment. Packets with the SYN flag set are processed the same way as a packet transporting data, they are retried until acknowledged.
  • Messages larger than packet size are retransmitted using multiple consecutive packets.
  • the maximum segment size depends on the transport mode used.
  • the “packet sequence number” is incremented independently by each side (source, target/destination) for each packet sent, which includes a SYN packet or a payload packet, excluding retries.
  • the “packet sequence number” is not incremented for packets sent as an acknowledgment (ACK).
  • ACK acknowledgment
  • the “package sequence number” of an ACK is not processed and is present primarily to keep the header fixed in size.
  • a packet received with a “packet sequence number” equal to the “packet sequence number” of the last packet received plus one has its payload transferred to the next layer up in the TIP protocol.
  • the ACK flag is not set in the first packet sent during a connection establishment and the “last received sequence number” is set to zero and not processed by the target node. Subsequent packets have the ACK flag set and the “last received sequence number” set to the “packet sequence number” of the last valid packet received.
  • the piggyback of ACK and data is done only if the data is available in time, e.g., within 500 msec, If not, then an empty packet is sent with the ACK flag set.
  • the type of acknowledgment-only packets are not retries. Packets received with the SYN, PSH, and RST flags set are not acknowledged and are processed if not duplicated. An unacknowledged packet is considered duplicated if received before timeout, e.g., eight (8) seconds, with the same “packet sequence number” and CRC.
  • a state diagram of the present technology is shown to illustrate how connections can be established and closed.
  • a node may open in one of two ways: passively 312 or actively 314 .
  • the node may passively open itself to communication by Listening 340 on the network for a SYN sent to its port.
  • a node e.g., a meter reporting an unexpected increase in usage, enters a new state, SYN Sent 320 , after sending a message with the SYN flag set.
  • a node Listens 340 to receive a SYN 342 and responds by sending a message with SYN and an ACK flags set 344 , putting the node in the SYN Received 330 state.
  • the node can return to the Closed 310 state by receiving a message with the RST flag set or via timeout 322 .
  • the node can enter the Connection Established 350 state upon receipt of a message with SYN and ACK flags set 324 after sending a message in response with the ACK flag set 326 ; or the node can open simultaneous communication 328 with another node by receiving a message with the SYN flag set and sending a message with the ACK flag set.
  • a receipt of a message with the ACK flag set 332 in response to a message sent with SYN and ACK flags set 344 moves the node to a Connection Established 350 state. If no message is received before a timeout occurs, or a message with the RST flag set is received while the node is in the SYN Received 330 state, then the node returns to the Listen 340 state. In other embodiments, the node returns to the Closed 310 state under those circumstances.

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This application is directed to systems, methods, and computer program products of a transport layer and transport model. The transport layer and transport model are particularly well adapted to the Automated Meter Infrastructure (AMI) and Automated Meter Reading (AMR) environments.
  • 2. Description of the Related Art
  • A mesh network is a wireless network configured to route data between nodes within the network. It allows for continuous connections and reconfigurations around broken or blocked paths by retransmitting messages from node to node until a destination is reached. Mesh networks differ from other networks in that the component parts can all connect to each other via multiple hops. Thus, mesh networks are self-healing: the network remains operational when a node or a connection fails.
  • AMI, AMR, or Advanced Metering Management (AMM) technologies include systems that measure, collect and analyze utility usage, from advanced devices such as electricity meters, gas meters, and water meters, through a network on request or a pre-defined schedule. This infrastructure includes hardware, software, communications, customer-associated systems and meter data management software. The infrastructure collects and distributes information to customers, suppliers, utility companies and service providers. This enables these businesses to either participate in, or provide, demand response solutions, products and services. Customers may alter energy usage patterns from normal consumption patterns in response to demand pricing. This improves system load and reliability.
  • Mesh networks may include at least one mesh gate and at least one mesh device, such as a meter. The mesh gate may communicate with the meters over a mesh network. The mesh gate may also communicate with a server over a wide area network. The mesh gate may form a mesh network with nearby meters and interface between the meters and the server.
  • The Open Systems Interconnection Basic Reference Model (OSI Reference Model or OSI Model) provides a layered, abstract description for communications and computer network protocol design, developed as part of the Open Systems Interconnection (OSI) initiative. It is also called the OSI seven layer model. The layers are conventionally, from top to bottom, Application, Presentation, Session, Transport, Network, Data Link, and Physical. A layer is a collection of related functions that provides services to the layer above it and receives service from the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of the path.
  • The typical or conventional Transport layer (layer 4) under the OSI model provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. The transport layer may typically control the reliability of a given link through flow control, segmentation and/or de-segmentation, and error control.
  • Although it was not developed under the OSI Reference Model and does not strictly conform to the OSI definition of the Transport Service, the best known example of a layer 4 protocol is the Transmission Control Protocol (TCP).
  • Of the actual OSI protocols, not merely protocols developed under the model, there have heretofore generally considered to be five classes of transport protocols, ranging from class 0 (which is also known as TP0 and provides the least error recovery) to class 4 (which is also known as TP4 and is designed for less reliable networks, similar to the Internet). Class 4 is closest to TCP, although TCP contains functions, such as the graceful close, which OSI assigns to the Session Layer.
  • The conventional or typical Network layer (Layer 3) under the OSI model provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks while maintaining the quality of service requested by the Transport layer. The Network layer performs network routing functions, and might also perform fragmentation and reassembly, and report delivery errors. One known example of a layer 3 protocol is the Internet Protocol (IP).
  • BRIEF SUMMARY OF THE INVENTION
  • The technology includes networks, network devices, and computer program products for implementing a transport layer. Each embodiment has a transport layer module operable to provide connection oriented transport layer services to an application layer, a presentation layer, and a session layer. The transport layer header flags essentially consist of: SYN, ACK, PSH, and RST. In some embodiments, a connection is terminated only by a computer program product operating on a network device sending or receiving a message with the RST flag set, or by a timeout. In some embodiments data can be transferred in a message from a receiving node containing the first set ACK flag of a connection. In some embodiments sequence numbers are assigned only at the packet level. In some embodiments, the packet level is the minimum level of data segmentation. In some embodiments, a transport layer implemented by the transport layer module directly interfaces with a data link layer without the presence of a separate network layer.

  • DETAILED DESCRIPTION OF THE INVENTION
  • Detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale, and some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention. Further, individual characteristics of the technology can be omitted from any given embodiment or combined in various ways to produce patentable embodiments of the technology.
  • For purpose of brevity of description, embodiments of the inventive transport layer and transport model, including implementing structures, methods and procedures, and computer program product and data structure features are referred to by the acronym TIP.
  • In combination with technologies that implement the functionality of other layers of a protocol stack, e.g., the technology described in pending U.S. Provisional Patent Application No. 60/989,957 as enabling transfers of short packets (e.g., 80 bytes of payload) between nodes within a mesh network (hereby incorporated herein by reference in its entirety), the present transport layer technology enables reliable transmission of large messages. The technology provides end-to-end acknowledgement of messages, rejection of duplicate packets, multi-packet messaging, and port multiplexing within a network node.
  • Referring to FIG. 1, the TIP protocol 100 is shown in the context of related AMI protocols. A protocol stack used in intra-mesh operations, e.g., between two permanently installed meters in neighbouring homes, is shown in the first column 110. A protocol stack for a conventional wide area network (WAN), e.g., TCP/IP-enabled devices in an AMI application, is shown in the third column 120. A simplified protocol stack used for direct communication during installation, maintenance, and walk-by of an AMI node is shown in the middle column 130.
  • TIP implements functions similar to IP and TCP in a single layer. With regard to IP functionality, TIP uses a smaller transmission unit, e.g., a single IEEE 802.15.4 packet. Version control, priority, flow label, payload length, next header, and hop limit as used in IP are not transported. Source address and destination address are only sometimes transported, as will be described in more detail below. Option headers are not used.
  • Further in contrast to TCP, TIP employs packet-level sequence numbers instead of byte-level sequence numbers—in protocol stacks employing TIP it is not allowed for an intermediate node to re-fragment a packet, hence the TCP byte-level sequence number is not required.
  • In contrast to TCP, TIP presents a single packet window. This approach is possible, in part, because some target networks employing TIP in the protocol stack, e.g., AMI networks, present homogeneous, half duplex, low latency characteristics. TIP is less complex than TCP to implement, requires less resources, and removes the need to include the window size in the header.
  • Under TIP, unlike under TCP, termination of a connection is through one message, i.e., RST, rather than through three, i.e., FIN, ACK, and then ACK. Further, offset and checksum are not transported; fixed timeouts are used; and the URG flag and urgent pointer are not supported. An early open feature, representing the ability to piggyback payload data during a three-way connection handshake, is provided.
  • In comparison to TCP/IPv6 packets, which introduce an overhead of at least 64 bytes on all packets, TIP introduces an overhead of 21 bytes for communication between an AMI node and an IPv6 node on the first packet of a communication, and only a 4-byte overhead on subsequent packets. For inter-mesh communication not involving a TCP/IP node in the route, both the first and all subsequent packets are burdened with only a 4-byte overhead.
  • Referring to FIG. 2, an AMI packet 200 including a TIP header 210 of the present technology is shown. The packet 200 includes: an IEEE 802.15.8 Media Access Control (MAC) header 220; a mesh network header 230; a header for layers above the transport layer in conventional protocols, shown as an Application Header 240; and a packet payload 250. As indicated above, for direct communication during installation, maintenance, and walk-by of an AMI node the mesh network header 230 is not used.
  • In some embodiments, the TIP header 210 includes an eight-bit flag field 212. The flag field 212 uses bits 5-7 (three bits) to indicate extension type. For example, in bits 5, 6, and 7, binary values 000 and 001 can be reserved to avoid conflicts with extended mesh network service; binary values 010, 011, and 111 also can be reserved; binary value 100 indicates intra-TIP communication; binary value 101 can indicate IPv4 communication with TIP; and binary value 110 can indicate IPv6 communication with TIP. Bit 4 is a flag for acknowledgment (ACK); bit 3 is a flag for the push message (PSH); bit 2 is a flag for the reset message (RST); bit 1 is a flag for synchronization (SYN). Finally bit 0 is reserved.
  • The TIP headers include an eight-bit sequence number 214 pre-incremented for each transmitted packet, excluding acknowledgement messages and retries. The TIP header also contains the value of the last packet sequence number received by the sender of the current packet.
  • TIP allows port addressing within a node. In some embodiments, ports 0-2 are inbound ports used for regular reporting, high priority reporting, and on-demand ANSI C12.22 respectively; ports 3 and 4 are reserved; ports 5-14 are outbound ports with 5-9 used for ASNI C12.22 relaying to WAN to LAN NATing and ports 10-14 used for internal processes such as mass upgrade and mass configuration of network nodes. In some embodiments, port 0 is reserved; port 1 is an outbound port for ASNI C12.22 reporting; port 2 is an inbound port for on-demand ANSI C12.22; ports 3-14 are reserved; and port 15 is an inbound RFD proxy port.
  • The TIP header further contains an extension field 218 defined by the extension type bits, e.g., bits 5-7 of the flag field 212, e.g., as one of intra-TIP, IPv4/TIP, and IPv6/TIP. When extension type is set to intra-TIP, the extension field 218 is formatted as an eight-bit field where bits 5-7 indicates a source port number; while bits 0-3 indicate a destination port number. When the extension type is set to IPv4/TIP, then the extension field is a seven-byte (56-bit) field using 32 bits for the IP address of the node on IPv4 network, 16 bits for the port number at the IPv4 address, and 8 bits for the port number of the TIP network address (though in some embodiments, less than 8 bits may be used). When the extension type is set to IPv6/TIP, then the extension field uses 128 bits for the IPv6 address, 16 bits for the port address at the IPv6 address, and the last 4 bits of the final byte for the port number of the TIP network address.
  • Implementations of the technology turn the relatively unreliable and very basic services provided by a data link layer into a more powerful technology for AMI communications through the use of a connection-oriented approach that provides same-order delivery, improved data reliability through retransmission of packets, flow control, streaming, and port addressing.
  • Regarding connection establishment, a communication is started between a source and a target (potential destination) by the exchange of packets with the SYN flag set. The initial “packet sequence number” is set to an arbitrary value from a range of valid sequence numbers to mitigate the risk of false duplicate packet detection. The “packet sequence number” returned is also set to a separate arbitrary value from the range. The “last received sequence number” returned from the destination is set to the “packet sequence number” received last by that node. The first packet is accepted by the target unless duplicated. The first packet is considered duplicated if received before the timeout, e.g., eight (8) seconds, with the same “packet sequence number” and CRC. Only packets received with the SYN flag set and a matching “last received sequence number” are processed as a connection establishment. Packets with the SYN flag set are processed the same way as a packet transporting data, they are retried until acknowledged.
  • Messages larger than packet size are retransmitted using multiple consecutive packets. The maximum segment size depends on the transport mode used.
  • The “packet sequence number” is incremented independently by each side (source, target/destination) for each packet sent, which includes a SYN packet or a payload packet, excluding retries. The “packet sequence number” is not incremented for packets sent as an acknowledgment (ACK). In fact, the “package sequence number” of an ACK is not processed and is present primarily to keep the header fixed in size. A packet received with a “packet sequence number” equal to the “packet sequence number” of the last packet received plus one has its payload transferred to the next layer up in the TIP protocol.
  • The ACK flag is not set in the first packet sent during a connection establishment and the “last received sequence number” is set to zero and not processed by the target node. Subsequent packets have the ACK flag set and the “last received sequence number” set to the “packet sequence number” of the last valid packet received. The piggyback of ACK and data is done only if the data is available in time, e.g., within 500 msec, If not, then an empty packet is sent with the ACK flag set. The type of acknowledgment-only packets are not retries. Packets received with the SYN, PSH, and RST flags set are not acknowledged and are processed if not duplicated. An unacknowledged packet is considered duplicated if received before timeout, e.g., eight (8) seconds, with the same “packet sequence number” and CRC.
  • Referring to FIG. 3, a state diagram of the present technology is shown to illustrate how connections can be established and closed. Beginning at the Closed 310 state for the convenience of description, a node may open in one of two ways: passively 312 or actively 314. The node may passively open itself to communication by Listening 340 on the network for a SYN sent to its port. A node, e.g., a meter reporting an unexpected increase in usage, enters a new state, SYN Sent 320, after sending a message with the SYN flag set.
  • In the passive mode, a node Listens 340 to receive a SYN 342 and responds by sending a message with SYN and an ACK flags set 344, putting the node in the SYN Received 330 state.
  • In the SYN Sent 320 state, the node can return to the Closed 310 state by receiving a message with the RST flag set or via timeout 322. The node can enter the Connection Established 350 state upon receipt of a message with SYN and ACK flags set 324 after sending a message in response with the ACK flag set 326; or the node can open simultaneous communication 328 with another node by receiving a message with the SYN flag set and sending a message with the ACK flag set.
  • In the SYN Received 330 state, a receipt of a message with the ACK flag set 332 in response to a message sent with SYN and ACK flags set 344 moves the node to a Connection Established 350 state. If no message is received before a timeout occurs, or a message with the RST flag set is received while the node is in the SYN Received 330 state, then the node returns to the Listen 340 state. In other embodiments, the node returns to the Closed 310 state under those circumstances.
  • FIG. 4 illustrates TIP aspects of a simple communication between nodes 400. Specifically, a single unsegmented request and unsegmented reply communication is shown. Node 410 sends 412 a first packet with SYN and PSH flags set, having a packet sequence number set to a arbitrary number within the valid packet sequence number range, e.g., 46, last received sequence set to 0, and a data payload (e.g., of a Protocol Specification for Electronic Metering (PSEM) request to Node 420). Node 420 responds 422 with a message having SYN, ACK, and PSH flags set, with its own arbitrary packet sequence number 22, and with last received packet sequence number equal to that of Node 410's last sent message 412; and with the response to the PSEM request as the data payload of the message. In some embodiments, node 410 closes the connection by sending 430 a message having an empty data field and the ACK and RST flags set.
  • FIG. 5 illustrates communication 500 between two nodes where the Node 510 sends 510 a message indicating the beginning of a segmented request (e.g., no PSH flag set), but Node 520 does not support segmented requests. Node 520 indicates such by sending 522 a packet with the RST flag set, last received packet sequence number with the correct value, and an empty data field. Node 510's message 520 indicated that a segmented request was starting by not setting the PSH flag.
  • FIG. 6 illustrates communication 600 between two nodes 610, 620 for a multiple unsegmented request/unsegmented response pairs. Each message from Node 610 bearing an unsegmented request, e.g., 612, 614, 616, has the PSH flag set. The first message 612 from Node 610 over the connection has the SYN flag set, while subsequent unsegmented messages 614, 616, 618 have the ACK flag set. The connection is terminated by Node 610 using a message 618 with the RST flag set.
  • FIG. 7 illustrates communication 700 between two nodes 710, 720 where node 710 sends an unsegmented request and node 720 responds with a segmented response. The unsegmented PSEM request is sent in message 712 with SYN and PSH (indicating that the message contains unsegmented data, e.g., data not divided across more than one massage) set. Node 720 responds with a message 722 having SYN and ACK flags set and data if the first segment of the PSEM response. Notice that the PSH flag is not set in messages 722 or 724 from node 720; this indicates to node 710 that more segments are to follow. Also notice that after sending 712 the unsegmented request, node 710 repeats the packet sequence number of its original request, but keeps track new packet numbers received from node 720.
  • FIG. 8 illustrates communication 800 between two nodes 810, 820 for a segmented request prompting an unsegmented response. The initial message 812 from node 810 has the SYN flag set, is numbered arbitrarily, and contains the first segment of a PSEM request. Node 820 responds with a message 822 having SYN and ACK flags set, its own arbitrary packet sequence number, and a confirmation of the packet sequence number first sent in the message 812 from node 810. The data field of message 822 is empty or ignored. Node 820 then sends messages 814, 816 with incremented sequence numbers and containing the remaining portions of the PSEM request. The message 816 containing the last portion of the PSEM request also has its PSH flag set, signalling the end of the PSEM request. Notice that Node 820 does not increment its packet sequence number when acknowledging subsequent segments of the PSEM request. Node 820 then responds 826 to the completed PSEM request with a packet having a sequence number incremented from the initial Node 820 number for this connection.
  • FIG. 9 illustrates communication 900 between two nodes 910, 920 for a segmented request and a segmented response. Node 910 sends a message 912 having the SYN flag set and having the first segment of the request in the data field. Node 920 responds with a message 922 having SYN and ACK flags set and provides its own packet sequence number. Node 910 then sends a message 914 with incremented sequence number and the remaining portion of the request—indicating that this is the final portion of the request by setting the PSH flag. Node 920 then begins responding to the request by sending a message 924 with the first segment of the response, the ACK flag set (but not the PSH flag set), and its own incremented sequence number. Node 910 then acknowledges receiving the first segment of the response with a message 916 having an empty data section and with only its ACK flag set. Node 920 completes the response by sending a message 926 having both ACK and PSH flags set. Node 910 then terminates the connection through a message 918 having ACK and RST flags set.
  • The examples of FIGS. 4-9 use piggybacking, e.g., the responding node 920 includes response data in the first acknowledging message (e.g., one having an ACK flag set, e.g., 924) after receiving the completed request (e.g., 914) from the sending node, e.g., 920. FIG. 10 illustrates communication between two nodes 1010, 1020 for an unsegmented request and segmented response when piggybacking is not possible, e.g., when response data is not available in a timely fashion, e.g., before the requesting node is expected to time out. In response to a message 1012 from node 1010 initiating communication (e.g., SYN flag set and packet sequence number assigned) for an unsegmented (e.g., PSH flag set indicating that this first segment is the last segment) data field, node 1020 replies with a message 1022 having SYN and ACK flags set, packets sequence number assigned, and last received packet sequence number acknowledged, but having an empty data field (possibly because data was not ready in time enough to respond timely to the request). Node 1010 responds 1014 to message 1022 with an un-incremented acknowledgment of receiving a message with the serial number 36. When data is ready, node 1020 begins an otherwise-routine transfer of each segment using messages 1026 and 1028. Node 1010 performs routine inter-segment acknowledgment 1016 and connection termination 1018.
  • Network devices of the present technology include mesh network end devices, mesh routers, and mesh coordinators. FIG. 11 illustrates a coordinator 1110 of the present technology serving to move data formatted in a UDP message 1122 from an IP node 1120 in an IP network 1124 to a TIP node 1130 of a mesh network 1131. If the UDP message 1122 has data longer than accommodated in a single TIP message data field, then the coordinator 1110 segments the data and handles establishing, maintaining, and terminating the connection with the TIP node 1130. Consistent with earlier description, the coordinator established communication through use of the SYN flag 1132, and responds to acknowledgement 1134 from the TIP node 1130 with successive data packets 1136 after receiving each acknowledgment 1138 until the last portion of the data is passed and a message including a set RST flag is sent 1139.
  • FIG. 12 illustrates a coordinator 1210 of the present technology facilitating communication between an IP node 1220 of an IP network 1224 sending a TCP-formatted message to a TIP node 1230 of a mesh network 1231. The coordinator 1210 interacts with the IP node 1220 to establish a connection 1222 before transferring data 1226 and then closing the connection 1228. While the coordinator 1210 relies on receiving TCP message information from the IP node 1220 before forwarding such information to the TIP node 1230, the coordinator 1210 otherwise interacts with the TIP node 1230 with timing independent of the IP network 1224 timing. The coordinator establishes a connection 1232 with the TIP node 1230, segments data received from the IP node 1220 and sends the re-segmented data 1234, and then terminates the TIP connection 1236 after all the data has been sent. Both the processes illustrated in FIGS. 11 and 12 can be reversed using the same principles.
