Abstract: Real time reliable multicast is a valuable communication approach for updating a small batch of distributed data synchronously and real-timely.By studying techniques of hiberarchical networks and active network in synthesis,a real time reliable multicast protocol based on the active NACK is presented.The protocol has characteristics of better scalablibility,strong ability to restrain network’s bursting traffic restraint and strict real-time.
