摘要： In one embodiment, a method includes receiving topology data that indicates multiple communication links and multiple intermediate network nodes in communication based on the communication links. The intermediate network nodes include multiple leaf nodes that terminate communications and multiple transit nodes that facilitate the passage of information between leaf nodes. Aggregation point data is also received, which indicates all aggregation points on the intermediate network nodes. An aggregation point is an interface between a network node and a communication link, through which is output data that is a combination of data received through multiple different interfaces upstream of the interface. A set of paths is determined for which each path in the set connects a different pair of leaf nodes. A measure of aggregation is determined based on a number of aggregated paths of the set of paths. An aggregated path passes through an aggregation point.

摘要： A method of processing both two-octet and four-octet autonomous system (AS) identifier values in a first network node that communicates with peer network nodes using Border Gateway Protocol (BGP), comprises receiving a first route message from a BGP peer node that is outside a local autonomous system that includes the first network node, wherein the BGP peer node can process only two-octet AS identifier values; identifying one or more extended community attributes in a route in the received route update message; for each of the identified extended community attributes, modifying the received route by creating an AS set containing four-octet AS identifier values carried in the identified extended community attributes, and attaching the AS set to the received route; and sending the modified received route to a third BGP node.

摘要： Techniques for implementing forwarding in network devices are provided. Proxy addresses are used in place of next hop addresses so that a large routing table is not required. Pairs of proxy IP and MAC addresses can be used to allow this optimization to occur completely transparent to any other device in the network. One or more smaller tables can be utilized in place of a large routing table to more efficiently implement forwarding. Additionally, the technique can be utilized without requiring modification of other hardware devices in the network.

摘要： A method for communicating packets in a network environment is provided that includes receiving a packet at a network element and identifying a sequence number included in the packet that correlates to awareness information associated with one or more adjacent network elements. A table included in the network element may be updated in order to account for the awareness information included within the packet that has not been accounted for by the network element. In cases where the awareness information included in the packet has already been accounted for, the packet may be ignored.

摘要： A system and method for keeping ledger accounts in synchronization between a back-end procurement system and a front-end requisition and catalog system. An extract utility extracts a file of general ledger (G/L) accounts, including account code, description, and company code, from a chart of accounts in the back-end and transfers it to the front-end, where it is updated by an update utility to include company group code from a company group table and then loaded into a data store of valid general ledger accounts. Maintenance of the front end data store of valid accounts includes pushing to all companies in a company group ledger code entered with respect to any one of the companies in that group.

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： 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.

摘要翻译： 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。

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： 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.
