    • 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.
    • 静态邻居配置的网络设备配置了静态邻居特性,包括网络设备的静态邻居列表。 静态邻居配置的网络设备位于包含动态配置的网络设备的网段中。 静态邻居配置的网络设备从动态配置的网络设备接收组播报文。 确定动态配置的网络设备是否包含在静态邻居配置的网络设备的静态邻居列表中。 如果在静态邻居配置的网络设备的邻居列表中找到动态配置的网络设备,则接收组播数据包。 此外,当接收到多播分组时,静态邻居配置的网络设备的邻接不会与任何其他当前相邻的网络设备丢失。

    • A system for optimizing the performance of a network. In an illustrative embodiment, the system includes a memory containing one or more data structures data structures. A first module determines transit-only information. A second module selectively omits the transit-only information from the one or more data structures. In a more specific embodiment, the one or more data structures include one or more tables. The transit-only information includes interface Internet Protocol (IP) addresses associated with network interfaces that are transit-only interfaces. The route information may include network topology information. The one or more tables may include a network topology table. Plural routers positioned in the network incorporate one or more instances of the system. The routers may employ one or more routing protocols, such as include Enhanced Interior Gateway Routing Protocol (EIGRP) or Routing Information Protocol (RIP).

    • Techniques for sending data in a packet-switched communications network include determining multiple subsets of adjacent network nodes of the network. The adjacent network nodes communicate without intervening network nodes with a particular network node through an interface on the particular network node. Each subset includes multiple adjacent network nodes. Subset definition data is sent through the interface. The subset definition data indicates which adjacent network nodes belong to which subset. Data for fewer than all adjacent network nodes in all subsets are sent by including, in a multicast data packet sent over the interface with a multicast destination address, subset identifier data that indicates a particular subset. When such data is received by a node, it is discarded unless the subset identifier matches the receiving node's subset identifier. Among other effects, this allows routing messages to be more efficiently sent to better performing neighboring network nodes.
    • 在分组交换通信网络中发送数据的技术包括确定网络的相邻网络节点的多个子集。 相邻的网络节点通过特定网络节点上的接口与特定的网络节点通信而无需中间网络节点。 每个子集包括多个相邻的网络节点。 子集定义数据通过接口发送。 子集定义数据指示哪些相邻网络节点属于哪个子集。 通过在通过接口发送的多播数据分组中包括指示特定子集的子集标识符数据,包括在所有子集中比所有相邻网络节点少的数据。 当节点接收到这样的数据时,除非子集标识符与接收节点的子集标识符相匹配,否则丢弃该数据。 除此之外,这使得路由消息更有效地发送到更好地执行的相邻网络节点。

    • 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.
    • 用于恢复丢失路由的技术包括从相邻节点接收向目的地发送数据的报告成本; 并将总成本确定为向相邻节点发送数据分组的成本的总和以及相应的报告成本。 确定具有最小总成本的选择的相邻节点作为到目的地的路由的下一跳。 确定报告成本小于所选择的相邻节点的总成本并且排除所选择的相邻节点的可行后继集合,以及关于可行后继集合的后继数据。 后继数据被发送到相邻节点。 丢失到特定目的地节点的路由的相邻节点能够基于后继数据来确定是否在向目的地恢复丢失路由的同时查询发送节点,从而减少网络资源消耗。
