In this paper, we propose a group communication approach which can provide quality of service for soft real-time applications. This proposed scheme combining the explicit multicast, end-point measure-based admission control scheme(EMBAC), and diffserv, removes the need of maintaining state information in the network, so that it would be easily deployable in real networks. We propose the scheme of node configuration to measure the quality of the diffserv network, and that of managing EMBAC over group communication environment. By simulation, we validate the QoS of the proposed multicast service network.
