Abstract: A communication method includes a first network device obtaining a first route and a second route from a second network device. A first network segment corresponding to the first route is a subnet segment of a second network segment corresponding to the second route. The second route is an aggregated route, and the first route indicates that the first network segment is unreachable. The first network device switches a next hop of the aggregated route based on the first route.

Abstract: This application provides a packet transmission method, apparatus, and device. For example, the method is performed by an ingress node. The ingress node obtains a second packet by using first node information carried in a first packet, where the first node information includes a first bit string indicating N next-hop devices of the ingress node and first reference information used for indexing second node information corresponding to a first intermediate node in the N next-hop devices, and the second packet includes a first identifier determined based on the first reference information. The ingress node sends the second packet to the first intermediate node. Because structures of the first bit string and the first reference information are used, a packet encoding manner is simple, so that packet transmission efficiency is improved.

Abstract: A self-organizing mesh network system is disclosed, comprising: at least one master node generating a timing reference signal; a plurality of regular nodes deriving time synchronization from the timing reference signal; and a wireless medium for communicating location and timestamp information among the plurality of regular nodes, The plurality of regular nodes may be configured to each use communicated location and timestamp information of nearby nodes to independently generate a location map of the nearby nodes. The plurality of regular nodes may be configured to accept an additional regular node. The plurality of regular nodes may be configured to allow a node of the plurality of regular nodes to exit the plurality of regular nodes. The plurality of regular nodes may each use communicated location and timestamp information of the plurality of regular nodes to independently generate a location map of each of the plurality of regular nodes.

Abstract: A method includes that a first routing device obtains a first identifier and a second identifier that are advertised by the second routing device. The first identifier is a bit forwarding router (BFR)-identifier (ID) of the second routing device that is valid in a bit indexed explicit replication (BIER) sub-domain to which the second routing device belongs. The second identifier is used to indicate being used only as a bit forwarding ingress router (BFIR). The first routing device skips, based on the first identifier and the second identifier, setting a bit that is in a forwarding bit mask (F-BM) and that corresponds to the first identifier. The F-BM is included in all BIER forwarding entries corresponding to the BIER sub-domain on the first routing device.

Abstract: A method comprises, at routers of a network configured to provide connectivity from a multicast receiver to edge routers multihomed to a multicast source of multicast traffic on an Ethernet segment: creating a limited flood domain for the Ethernet segment, wherein the limited flood domain includes boundary routers positioned to make a final decision as to which of the edge routers to send a multicast join for the multicast traffic; by the boundary routers, upon receiving a source announcement that announces the multicast source is active on a particular edge router of the Ethernet segment, locally storing information, provided by the source announcement, which includes a multicast address for the multicast source and identifies a link to the particular edge router; and by boundary router of the boundary routers, upon receiving the multicast join, sending the multicast join to the particular edge router using the multicast address and the link.

Abstract: The present invention discloses a clustering routing optimization method based on adaptive evolutionary algorithm for a wireless sensor network, comprising following steps: performing population initialization by initial position and energy information of sensor nodes; calculating fitness values, and implementing iterative operation of elite preservation, adaptive crossover and mutation; after the iteration, selecting a cluster head; routing data packet of the cluster head to a base station. Convergence process of the evolutionary algorithm is improved by nonlinearly adjusting the probability of crossover and mutation; upper and lower bound of crossover and mutation operators are dynamically adjusted by fitness value; adding an incentive factor, adjusting the crossover and mutation probability when the fitness value tends to converge, and running the algorithm again to confirm that a new optimal value is generated. The global search capability and convergence speed of the algorithm are improved by the above method, and avoiding local convergence.
