摘要： In an example embodiment, a method and system is provided to determine and advertise a route advertisement in a reactive routing environment. In response to receiving a network address query with respect to a destination address at a routing device, an aggregate value, e,g, an address prefix, is determined and advertised in reply to the network address query. Determining of the aggregate value may comprise identifying within a range of network addresses represented by the aggregate value respective addresses for which the routing device does not have reachability information. The routing device may send address queries with respect to the identified addresses, to determine reachability via the routing device of those addresses. The aggregate value may be advertised conditional upon determining that a percentage of addresses within the corresponding range that can be reached via the routing device satisfies a predefined minimal coverage value.

摘要： Each mobile router in a mobile ad hoc network is configured for identifying routes to nearby nodes that are within a prescribed distance, based on storage of explicit paths specified within routing headers of packets transmitted from a host node to a destination node. Each mobile router also can selectively compress the routing header, based on the storage of the explicit path, resulting in a loose source route type routing header in the packet output from the mobile router. In addition, a routing header of a received packet can be expanded based on the mobile router inserting the explicit path, enabling mobile hosts in the explicit path to forward the packet according to strict source routing. The storage and compression of explicit paths also can be applied to packets specifying reverse routing headers, minimizing the size of the reverse routing headers.
摘要翻译：移动自组织网络中的每个移动路由器被配置为基于在从主机节点发送到目的地节点的分组的路由头部中指定的显式路径的存储来识别在规定距离内的附近节点的路由。每个移动路由器还可以基于显式路径的存储来选择性地压缩路由头部，导致从移动路由器输出的分组中的源路由类型路由头部松散。另外，可以基于插入显式路径的移动路由器来扩展接收到的分组的路由报头，使得显式路径中的移动主机能够根据严格的源路由转发分组。显式路径的存储和压缩也可以应用于指定反向路由头的分组，最小化反向路由头的大小。

摘要： The designated forwarding device functionality for forwarding of packets originated on a broadcast link among layer 2 is shared among multiple forwarding devices of different adjacency networks. As these networks do not form adjacencies, the forwarding devices do not natively participate in a same spanning tree for determining how to forward packets, and a designated forwarding device is used for forwarding packets originated on the common broadcast link. Distributing the role of a designated forwarding device among multiple of the forwarding devices provides a means for more efficiently forwarding packets to their destinations.
摘要翻译：用于转发在层2之间的广播链路上的分组的指定转发设备功能在不同邻接网络的多个转发设备之间共享。由于这些网络不形成邻接关系，所以转发设备本身不参与相同的生成树，以确定如何转发数据包，并且指定的转发设备用于转发在公共广播链路上发起的数据包。在多个转发设备之间分配指定转发设备的角色提供了一种更有效地将报文转发到目的地的方法。

摘要： Each router in a network is configured for generating router advertisement messages according to a flooding distance vector routing protocol. Each router advertisement message output according to the flooding distance vector routing protocol includes reachability information for at least one destination, and an originating router identifier indicating a router having originated the reachability information. If any router receiving the router advertisement message detects a match between the originating router identifier and the corresponding assigned router identifier, the received router advertisement message is disregarded during calculation of the best paths from the network. If the originating router identifier identifies another router, the router floods the received router advertisement message to other ports, and output its own router advertisement message based on the received router advertisement message and that specifies the originating router identifier from the received router advertisement message.
摘要翻译：网络中的每个路由器被配置为根据洪泛距离向量路由协议来生成路由器通告消息。根据洪泛距离向量路由协议输出的每个路由器通告消息包括至少一个目的地的可达性信息，以及指示已经发起可达性信息的路由器的始发路由器标识符。如果接收到路由器通告消息的任何路由器检测到始发路由器标识符和对应的分配的路由器标识符之间的匹配，则在从网络计算最佳路径期间忽略接收到的路由器通告消息。如果始发路由器标识符识别另一个路由器，则路由器将接收的路由器通告消息洪泛到其他端口，并根据接收到的路由器通告消息输出自己的路由器通告消息，并从接收到的路由器通告消息中指定始发路由器标识符。

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.
