基于监听的组播服务管理分析与研究

Analysis and Research of Monitoring-Based Multicast Service Management

导致组播应用存在问题的原因之一是缺乏服务管理。现今,组播面临转折,服务管理是否有效将决定组播能否在专有网络和Internet中继续使用。分析近期组播服务管理方面的研究工作,全文关注点是:域内和域间组播服务管理存在的问题及解决方法;监听信源和信宿间的组播可达性;测定端到端路径上的组播存在性。

One of the reasons for partial success in multicast is lack of support for service management. IP multieast is at a crossover today, and the continued use of multicast within private networks and across the Internet depends on effective service management. This article surveys some of the recent service management efforts, and focuses on challenges and solutions between intra - and interdornain service management; monitoring multicast reachability between sources and receivers; determining whether multicast capability exists on an end - to- end path.
