摘要： One embodiment identifies all one-hop neighbor nodes and two-hop neighbor nodes of a node; determines an active set of one-hop neighbor nodes for the node, comprising: includes in the active set each one-hop neighbor node that is either an edge node or connected with at least one two-hop neighbor node with which no other one-hop neighbor nodes are connected; and if the active set is not yet complete, then: determine all combinations of one-hop neighbor nodes that are not already in the active set; and tests each combination in order of each combination's total-energy value to determine whether a specific combination is able to complete the active set; if no combination is able to complete the active set, then including all one-hop neighbor nodes in the active set; and communicates a message to each one-hop neighbor node in the active set indicating that it is in the active set.

摘要： In certain embodiments, performing a defensive procedure involves receiving at a first speaker of a first autonomous system a path advertisement from a second speaker of a second autonomous system. The path advertisement advertises a path from the second speaker of the second autonomous system. It is determined whether the second autonomous system is a stub autonomous system and whether a path length of the path is greater than one. If the second autonomous system is a stub and the path length is greater than one, a defensive measure is performed for the path. Otherwise, a default procedure is performed for the path.

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： 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.
