摘要： Techniques for synchronizing routing data include determining whether conditions are satisfied for one-way transfer with an adjacent router. If it is determined that conditions are satisfied for one-way transfer of routing table data with the adjacent router, then a refresh-notice message is sent from the initiating router to the adjacent router. The refresh-notice message includes data that indicates a particular direction for transfer of routing table data. If the particular direction is inbound, then a copy of an adjacent routing table is received without sending a copy of the initiating router's own routing table. If the particular direction is outbound, then a copy of the own routing table is sent without receiving a copy of the adjacent routing table.

摘要： A method and apparatus are presented for determining network nodes for aggregating addresses in routing information used for routing data packets over a network. Link data and reachability data are received. Link data indicates direct links between each of multiple candidate routers of a network and a different router or a network segment. Reachability data indicates a set of one or more contiguous network addresses that can be reached on each link described in the link data. A measure of possible aggregation of contiguous network addresses is determined at the candidate routers based on the link data and the reachability data. A preferred router to aggregate addresses in routing information sent between routers in the network is determined among the candidate routers based on the measure of possible aggregation at each candidate router.

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： Techniques for recovering lost routes include receiving reported costs for transmitting data to a destination from neighboring nodes; and determining total costs as a sum of costs for transmitting data packets to the neighboring nodes and a corresponding reported cost. A selected neighboring node with a minimum total cost is determined as the next hop for the route to the destination. A feasible successor set of neighboring nodes which have reported costs less than the total cost of the selected neighboring node and excluding the selected neighboring node, and successor data about the feasible successor set, are determined. The successor data is sent to the neighboring nodes. A neighboring node that loses a route to the particular destination node is able to determine whether to query the sending node while recovering a lost route to the destination based on the successor data, thereby reducing network resource consumption.

摘要： Techniques for sharing routing information over a network include determining whether the scale of a flooding domain exceeds a threshold. If so, then a router announcement message is sent over a particular link. The message indicates the local router is a flooding domain border router (FDBR). Summary routing information is determined with less than a certain level of detail used in the flooding domain for routers connected to the local router through links different from the particular link. The summary routing information is sent over the particular link in a link state message that includes type data that indicates summary routing information that crosses a FDBR. These techniques allow automatic favorable scaling of domains of shared routing information as the size of a mobile ad hoc network grows.

摘要： Techniques for detecting loops in routes that cross route information boundaries include receiving a control message at a first edge node on one side of the boundary that is connected to a different second edge node on another side of the boundary. The control message indicates a particular network address of a particular node that is reachable from the first edge node. Distinguisher data is determined that indicates if a node in the first collection can reach the first edge node without leaving the first collection. An advertising message is sent from the first edge node to the second edge node that includes route data that indicates the particular network address and the distinguisher data. Based on the distinguisher data, a testing edge node in the first collection can determine whether there is a loop comprising both an internal path and an external path to the first edge node.

摘要： In one embodiment, a method includes receiving authenticated site data that includes site ID data and address data. The site ID data indicates a unique site ID for each site among multiple sites for a first network that uses an internal routing protocol. Multiple edge sites of those sites are separate from each other and connected to a second network that is under separate administrative control of at least one different party. The address data indicates network addresses associated with each site of the plurality of sites. An external routing protocol message is discounted based on the authenticated site data.
