20210377168 · 2021-12-02 · ·

A BIERv6 packet forwarding method, device, and system. The method includes: receiving, by a first network device, a BIERv6 packet, where the first network device is a BFR or a BFER; determining, by the first network device, whether a value of a hop limit field in the BIERv6 packet is less than or equal to a preset threshold of the first network device, where the preset threshold is a value greater than or equal to 2, and is determined based on a quantity of one or more consecutive second network devices connected to the first network device, and the second network device is a device that does not support BIER forwarding; and when the value of the hop limit field in the BIERv6 packet is less than or equal to the preset threshold, avoiding, by the first network device, forwarding the BIERv6 packet.

INFRASTRUCTURE LINK PATH ARRANGEMENT DETERMINATION METHOD AND SYSTEM

A computer-implemented method and system for determining a path arrangement of an infrastructure link. The method includes receiving one or more inputs each indicative of a constraint; and processing the one or more inputs and a set of data based on a path arrangement determination model. The set of data includes data representing one or more factors affecting the path arrangement. The method also includes determining, based on the processing, the path arrangement of the infrastructure link.

PATH COUNT MANAGEMENT

This disclosure describes techniques for managing path counts at a router. The techniques include monitoring available storage space at a router for storing per prefix routes. In an instance where the available storage space at the router may be inadequate to support continued, stable network operations, the techniques include reducing an amount of per prefix routes that are advertised to the router. The techniques may also include withdrawing previously advertised per prefix routes from the router. As such, path count management concepts may help prevent overload of storage space at a router.

SHARING CHANNEL OCCUPANCY TIME ACROSS NODES OF AN INTEGRATED ACCESS BACKHAUL NETWORK

Wireless communications systems and methods related to sharing channel occupancy time (COT) for a channel in an unlicensed 5G spectrum in an integrated access backhaul (IAB) network are provided. In some aspects, an IAB node of the IAB network may perform a channel access procedure to acquire the COT and share the COT with a parent IAB node and/or a child IAB node for the parent IAB node and/or child IAB node for the parent IAB node and/or child IAB node to share, or use the COT for communication, with a third IAB node different from the COT-initiating IAB node.

PIECEWISE SHORTEST PATH FIRST ROUTING

A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a route through the limited portion of the network to the target node is determined, other nodes are configured (e.g. via source routing) to cause the packet to traverse the determined route, and the packet is forwarded toward the target node.

SPLIT-BRAIN PREVENTION IN A HIGH AVAILABILITY SYSTEM DURING WORKLOAD MIGRATION

In some embodiments, a method receives a control message from a second host. The control message includes a first address to use as a next hop to reach an active workload that has migrated to the second host from another host. The method reprograms a local route table to include a policy to send packets to check a liveness of the active workload with the next hop of the first address. A packet is sent from a standby workload to the active workload using the next hop of the first address to check the liveness of the active workload. The packet is encapsulated and sent between the first host and the second host using an overlay channel between a first endpoint of the overlay channel on the first host and a second endpoint of the channel on the second host.

Data stream transmission

A Software Defined Network (SDN) controller determines a plurality of paths for transmitting a data stream from a first network device to a second network device. The SDN controller assigns to each of the plurality of paths a path identifier, where the path identifier is uniquely corresponding to the path and the specified service. The SDN controller delivers forwarding information to a network device other than the second network device on the path. The forwarding information is configured to instruct forwarding a data stream carrying the path identifier of the path to a next hop on the path of a network device receiving the forwarding information. The SDN controller selects a path from the plurality of paths and transmits a path identifier of the selected path to the first network device. The first network device adds the path identifier of the selected path to the data stream of the specified service.

VINE: ZERO-CONTROL ROUTING USING DATA PACKET INSPECTION FOR WIRELESS MESH NETWORKS
20210367878 · 2021-11-25 ·

A MANET protocol, comprising: receiving a data packet (DP) from a current sender (CS) by a recipient, defining: an identity of the CS, a prior sender (PS) from which CS received DP, and a target recipient (ID), a count (HC) of hops previously traversed by DP, and a sequence identifier (SI); updating a forwarding table (FT) to mark CS as being reachable in one hop, and PS as being reachable in two hops via CS as next hop; determining if ID is the recipient; determining whether to rebroadcast by recipient, if and only if the SI is not present in a list of prior SIs; and selectively rebroadcasting DP by recipient in dependence on said determining, modified by: replacement of CS with an identity of the recipient, PS with CS, and ID with a next hop from the FT if present, and incrementing HC.

FILE CONTROL FOR DATA PACKET ROUTERS USING CONSENSUS AND INTER-PLANETARY FILE SYSTEM (IPFS)

Packet routers route data packets based on existing topology files. The packet routers hash the existing topology files into content-addressed objects and exchange the content-addressed objects. One of the routers modifies its topology file into a new topology file, hashes the new topology file into a new content-addressed object, and transfers the new content-addressed object to the other packet routers. The packet routers exchange the content-addressed objects, and in response, exchange the topology files. The routers establish a consensus on the new topology file based on the existing topology files. The one packet router routes additional data packets based on the new topology file in response to the consensus. In some examples, the content-addressed objects comprise Inter-Planetary File System (IPFS) objects.

A distribution of a content selection being distributed throughout a wireless mesh network may be tracked. A wireless device in the wireless mesh network enables the content selection to be exchanged. Wireless devices then exchange the content, and a network topology is recorded in response. Finally, the network topology is reported to a reporting agent.
