Active multicasting for heterogeneous groups

摘要

Communication environments are becoming increasingly heterogeneous.This imposes new challenges on comunicatin support for multimedia and collaborative applciations.AMnet (Active Multicasting Network) provides multi-point communciation support for large-scale pgroups with heterogeneous receivers.Active Multicasting nodes inside the network include so-called QoS filters that remove information from continuous media streams in order to reduce data rate for low-end receivers without affecting high-end recerivers.A prototype implementation of AMnet based on RSVP is presented with some first performance results.
