| 摘 要： | 应用层组播(application-layer multicast,简称ALM)是网络层组播的重要补充.但与网络层组播不同的是,应用层组播结构的组成节点是具有独立利益和决策的主机用户.自私的主机用户为了提高自身利益,可能不严格遵守应用层组播协议的规定,从而对组播会话的整体性能带来影响.为了设计可信任的、鲁棒的应用层组播协议,对应用层组播的用户自私性进行研究是必要的.综述了这一领域的研究进展,并按照应用层组播协议的工作阶段把这些研究分为3类,即控制结构维护阶段的自私性研究、节点信息收集阶段的自私性研究以及数

| Abstract: | Application-Layer multicast (ALM) is an important supplement to IP multicast. However, unlike in IP multicast, the participating nodes in ALM are selfish and strategic host users. In order to improve their own interests, selfish host users might not strictly obey the ALM protocols, because of which the overall performance of the multicast session could be affected. To design robust and trustworthy ALM protocols, it is necessary to study the selfishness in ALM. This paper surveys the recent research trends in this area, and classifies the researches into three categories according to the working steps of ALM protocols, that is, the selfishness in maintenance of control structure, the selfishness in collection of node information, and the selfishness in construction of data structure. |
