摘要： Each mobile ad hoc node has an assigned hierarchy position within an identified tree-based aggregation group. Each ad hoc node is configured for selectively attaching to one of a plurality of available ad hoc nodes based on identifying a best match, for the assigned hierarchy position within the identified aggregation group, from among identifiable hierarchy positions of identifiable aggregation groups. Each ad hoc node also is configured for selectively attaching to any available ad hoc node based on a determined absence of any available ad hoc node advertising the identified aggregation group of the ad hoc node, or an aggregation group containing the identified aggregation group. Hence, a root node of an aggregation group can filter group-specific routing information from packets destined toward a network clusterhead, resulting in a scalable routing protocol that is not adversely affected by added nodes.

摘要： A method and apparatus for sharing routing information include receiving first domain data that indicates domains of a first mobile router. A domain is a collection of routers that share uniform routing information at a particular level of detail. An inbound data packet is received from a second mobile router over a particular link. The inbound control plane packet lists second domain data that indicates domains of the second mobile router. The first domain data and the second domain data together include multiple domains. A particular domain is automatically selected from the first domain data and the second domain data. The second mobile router independently selects the same particular domain. The particular link is assigned to the particular domain; and routing information for the particular domain is shared between the first mobile router and the second mobile router over the particular link.

摘要： A technique dynamically configures and verifies routing information of broadcast networks using link state protocols in a computer network. According to the novel technique, a router within the broadcast network receives a link state protocol routing information advertisement from an advertising router, e.g., a designated router or other adjacent neighbor. The router learns of a next-hop router (“next-hop”) to reach a particular destination from the advertisement, and determines whether the next-hop is located within the same broadcast network (e.g., subnet) as the designated router. If so, the router further determines whether the next-hop is directly addressable (i.e., reachable), such as, e.g., by checking for link adjacencies to the next-hop or by sending request/reply messages (e.g., echo messages or “ping” messages) to the next-hop. In the event the next-hop for the destination is not directly addressable by the router (e.g., no adjacency or reply), the router installs a route to the destination via the designated router. Otherwise, the router installs a route to the destination via the next-hop.
摘要翻译：技术使用计算机网络中的链路状态协议来动态地配置和验证广播网络的路由信息。根据该技术，广播网络内的路由器从广告路由器（例如，指定路由器或其他相邻邻居）接收链路状态协议路由信息广告。路由器学习下一跳路由器（“下一跳”）从广告到达特定目的地，并且确定下一跳是否位于与指定路由器相同的广播网络（例如，子网）内。如果是这样，则路由器进一步确定下一跳是否可直接寻址（即可达到），例如通过检查下一跳的链路邻接或通过发送请求/应答消息（例如，回波消息或“ ping“消息）到下一跳。在目的地的下一跳不能由路由器直接寻址的情况下（例如，没有邻接或回复），路由器经由指定的路由器安装到目的地的路由。否则，路由器将通过下一跳安装到目的地的路由。

摘要： A static neighbor configured network device is configured with a static neighbor feature including a static neighbor list of network devices. The static neighbor configured network device is in a network segment that includes a dynamically configured network device. The static neighbor configured network device receives a multicast packet from the dynamically configured network device. It is determined if the dynamically configured network device is included in the static neighbor list of the static neighbor configured network device. The multicast packet is accepted if the dynamically configured network device is found in the neighbor list for the static neighbor configured network device. Also, adjacency for the static neighbor configured network device is not lost with any other currently adjacent network devices when the multicast packet is received.

摘要： The present invention elects an area border router from a plurality of potential area border routers by determining a full set of all areas attached to a router. A determination is made as to a full set of area pairs from the determined full set of areas. Routers are identified in a first area of the determined full set of areas that are reachable through an intra-area route in the first area, and routers are identified in a second area of the determined full set of areas that are reachable through an intra-area route in the second area. If there is a router that is unreachable through either an intra-area route in the first area or an intra-area route in the second area, then declare the first router to be an area border router, else new first and second areas are selected.

摘要： Group key management in a mobile ad-hoc network (MANET) may be provided. Each network node associated with the MANET may comprise a group distribution key and a list of authorized member nodes from which a group key manager may be elected. The group key manager may periodically issue a new group key to be used in protecting communications among the network nodes. A compromised node may be excluded from receiving updated group keys and thus isolated from the MANET.
