新型网络应用要求通信协议提供多点投递和相应群组管理功能,同时,高速传输服务和新型网络层协议也开始具有数据多点传输和简单群组控制能力,跨越两者的运输层协议,从而又重新成为学术研究和标准化的热点和趋势.文章主要描述建立群组通信抽象模型的过程和结论以及参照新型运输协议XTP(express transport protocol)和计算机会议应用的模型映射和评价.
Novel applications require multicast delivery and group management abilities from communication facilities. For high-speed transmission services and new network layer protocols have already provided some issues interested, research on transport protocols has become a hot topic again both in academy and standardization sectors. The group communication model which the authors get, the projections for lightweight transport protocols XTP and computer conferencing applications are described in this paper.
