Executive Summary

This paper reviews the scenarios where a given message is sent from a single source to possibly several destinations. These scenarios can be subdivided into multicasting, geocasting, multiratecasting, and anycasting. In multicasting, a given message must be routed from one node to a number of destinations whose locations may be arbitrary and spread over the network. Geocasting destinations are all nodes located in a given geographical area. Multiratecasting is a generalization of multicasting, where regular messages are sent from a source to several destinations, possibly at a different rate for each destination.
