INTERNET - DRAFT TBRPF 2 March

چکیده
Topology Broadcast based on Reverse-Path Forwarding (TBRPF) is a proactive, link-state routing protocol designed for use in mobile ad-hoc networks. TBRPF has two modes: full topology (FT) and partial topology (PT). TBRPF-FT uses the concept of reverse-path forwarding to reliably and efficiently broadcast each topology update in the reverse direction along the dynamically changing broadcast tree formed by the min-hop paths from all nodes to the source of the update. TBRPF-PT achieves a further reduction in control traffic, especially in large, dense networks, by providing each node with the state of only a relatively small subset of the network links, sufficient to compute minimum-hop paths to all other nodes. In both the FT and PT modes, a node forwards an update only if the node is not a leaf of the broadcast tree rooted at the source of the update. In addition, in the PT mode, a node forwards an update only if it results in a change to the node’s source tree. As a result, each node reports only changes to a relatively small portion of its source tree. Bellur, Ogier, and Templin Expires 2 September 2001 [Page i] INTERNET-DRAFT TBRPF 2 March 2001
