Multicasting over ATM using connection server

This paper proposes a connection managing scheme, called the connection server (CS), for supporting intra-domain connectionless multicast over ATM. The intention of using CS is to relieve multicasting hosts from directly being involving in ATM call setup and release, so that the dynamic membership transition of a host group has minimal impact on all steady members in the group. It also eliminates the needs for dynamic address resolution, and enables virtual circuit (VC) reuse at membership management level. The paper presents the proof-of-concept implementation of the CS system, including the server/client signaling protocol and the ATM user datagram protocol (AUDP) which is designed as a typical CS application to provide multicast users with efficient transport services
