在过去的几年里，因特网上的多播通信越来越受到人们的关注。如今，有越来越多的应用需要具有多点通信能力的通信系统。多播通信既减少了向大量接收者发送数据所花费的时间，又减少了传递此类数据所需的网络资源量。这就是为什么互联网服务提供商（ISP）迫切需要网络产品供应商提供的多播解决方案。现在的问题是，多播还要多久才能成为真正的互联网服务。本文介绍了一个新的组播建议，MNet项目，这是正在开发的通信和电信实验室的信息工程系的科英布拉，葡萄牙。该方法探讨了使用多播服务器结合的SSM（源特定的多播）协议，解决了一些SSM的限制，其中支持动态源和QoS异构性的支持是最重要的。经过介绍和讨论，评估结果进行了分析，表明该模型是有益的，与原来的SSM解决方案相比。
Multicast communication in the Internet has deserved increasing attention in the last few years. Nowadays, there are more and more applications that require communication systems with multipoint communication capabilities. Multicast communication reduces both the time it takes to send data to a large set of receivers and the amount of network resources required to deliver such data. This is why Internet service providers (ISPs) have a strong need for multicast solutions from vendors of networking products. The question now is how long it will be before multicast becomes a true Internet service. The paper presents a new multicast proposal, the MNet project, that is being developed at Laboratory of Communication and Telematics of the Informatics Engineering Department of the University of Coimbra, Portugal. The approach explores the use of multicast servers in conjunction with the SSM (source specific multicast) protocol, addressing some of the SSM limitations, of which the support of dynamic sources and the support of QoS heterogeneity are the most important. After presentation and discussion, evaluation results are analysed, showing that the proposed model is beneficial when compared with the original SSM solution.
