Abstract

A large-scale active reliable multicast protocol:LARMP is presented.LARMP resolves five crucial problems of reliable multicast in the Internet such as negotiate acknowledge / acknowledge implosion,scope retransmission etc.LARMP employs an active dynamic multicast tree supported by the four-level active routers.The active routers in the tree implement the creation and maintenance of the active dynamic multicast tree,NACK suppression,NACK/ACK aggregation,datagram buffering,limitation of the delivery of repair packets to the nodes experiencing loss,and timely detection and report of net congestion to allow the sender to adjust its sending speed.The initial experiments have shown good performance.

Key words

multicast / active router / NACK / ACK / active datagram
