Abstract: A method for creating a single virtual LAN including a source (S) attached to a first Token ring LAN (N1), a target (T) within a subnet attached to a different Token ring LAN (N2), and an interconnecting router (R). The source (S) encapsulates the first packet with a Token ring header including the router MAC address (RMAC), SMAC as source MAC address as layer 2 information, and IP address of T (TIP) as layer 3 data and sends this packet over N1 toward the router. When receiving the first packet, R reads its IP table for best match with TIP address to identify the subnet including T. The net handler runs an ARP protocol to identify TMAC address, substitutes the MAC header with said TMAC address into said first packet destination MAC address field and forwards said first packet over N2. R then sends a conventional ICMP message over N1 limited broadcast and reconfigures itself in proxy ARP for the defined subnet. For the second packet, S runs an ARP and R answers with RMAC address and the RIF data to be used for next packets.

Abstract: In one embodiment, sensor data is transported in a network to a rendezvous point network node, which consolidates the information into a consolidated result which is communicated to the destination. Such consolidation by a network node reduces the number of paths required in the network between the sensors and the destination. One embodiment includes acquiring, by each of a plurality of originating nodes in a wireless deterministic network, external data related to a same physical event; communicating through the network said external data from each of the plurality of originating nodes to a rendezvous point network node (RP) within the network; processing, by the RP, said external data from each of the plurality of originating nodes to produce a consolidated result; and communicating the consolidated result to a destination node of the network. In one embodiment, the network is a low power lossy network (LLN).

Abstract: In one embodiment, a device (e.g., switch or registry) maintains a binding table for all internet protocol (IP) addresses in a particular subnet associated with the device, and in response to receiving a neighbor solicitation (NS) lookup message from a router for a particular address, determines whether the particular address is within the binding table. When the particular address is not within the binding table, the device causes the router to not store the particular address in a neighbor discovery (ND) cache at the router (e.g., by responding to clear the cache, or ignoring to prevent state from being created). In another embodiment, the ND-requesting router ensures that the particular address is not kept in an ND cache at the router in response to the device indicating that the particular address is not within its binding table (e.g., an explicit response to clear, or absence of instruction to store state).

Abstract: An autonomous wireless mobile network is established between mobile nodes configured as wireless autonomous robotic mobile access points. Each mobile node includes a mobility platform, an executable routing resource, and a standardized interface. The mobility platform is configured for supplying sensor data from attached physical sensors, and responding to motor commands from the standardized interface. The standardized interface is configured for converting each sensor datum into a corresponding sensor object, and converting received movement directives into the respective motor commands. The executable routing resource is configured for maintaining a database of world objects representing attributes within an infosphere established by the wireless mobile network based on the sensor objects and received network objects. The executable routing resource also is configured for generating the received movement directives and executing network decisions based on periodic evaluation of the world database, and exchanging the world objects with other mobile nodes.

Abstract: In one embodiment, a method includes receiving an inbound data packet over a wireless link at a wireless intermediate network node. The inbound data packet indicates the packet was transmitted by a node at an edge of the mesh. The inbound data packet is associated with a low priority minimum wait interval and a low priority maximum wait interval for reducing contention on the wireless link. An outbound data packet based on the first data packet is transmitted over the wireless link after a wait time. The wait time is based on a high priority minimum wait interval and a high priority maximum wait interval for reducing contention. The low priority minimum wait interval is greater than the high priority minimum wait interval. These techniques allow long packet queues at the edge but quickly clear packets already forwarded by the mesh.
