Abstract

The new Directed Reverse Path Join (DRPJ) protocol efficiently implements a Greedy routing algorithm for generating a multicast tree. The DRPJ protocol minimizes the messaging overhead from probe messages and allows a joining node to find multiple paths that are not constrained to be only the shortest paths. This enables a controllable tradeoff between path length and bandwidth consumption. Using simulation, the DRPJ protocol is compared to the existing Flooding with TTL (Time-To-Live) and Directed Spanning Join (DSJ) protocols. Using a topology model of the current Internet, it is found that the DRPJ protocol reduces probe messages by nearly 90 and 75% when compared to the Flooding with TTL and DSJ protocols, respectively.
