Title: (EN) Arrangement for providing network prefix information from attached mobile routers to a clusterhead in a tree-based ad hoc mobile network
(ZH) 自组网络、移动路由器和用于该移动路由器中的方法
Abstract: front page image
(EN) Mobile routers establish a tree-based network topology in an ad hoc mobile network, the tree-based network topology having a single clusterhead and attached mobile routers. Each attached mobile router has a default egress interface configured for sending messages toward the clusterhead, and ingress interfaces configured for receiving messages from attached network nodes that are away from the clusterhead. A neighbor advertisement message received from an ingress interface away from a clusterhead is used by the attached mobile router to identify specified network prefixes that are reachable via the source of the neighbor advertisement message. The attached mobile router outputs on its default upstream interface a second neighbor advertisement message that specifies the network prefix used by the attached mobile router, and the specified network prefixes from the neighbor advertisement message received on the ingress interface. Hence, connectivity is established with minimal routing overhead.

移动路由器在自组移动网络中建立基于树的网络拓扑(图1),所述基于树的网络拓扑具有单个群头和附接的移动路由器。每个附接的移动路由器具有被配置用于向群头发送消息的默认出口接口,以及被配置用于接收来自远离所述群头的附接的网络节点的消息的入口接口。接收自远离群头的入口接口的邻居通告消息被附接的移动路由器用于识别可经由邻居通告消息的源到达的指定网络前缀。附接的移动路由器在其默认上行接口上输出指定该附接的移动路由器所使用的网络前缀以及来自在入口接口上接收到的邻居通告消息的指定网络前缀的第二邻居通告消息。因此,以最低限度路由选择开销建立了连通性。
