【摘要】 组播关键技术之一是组成员通过隐式加入和显示加入构造一棵组播树。针对显示加入提出了一种带QoS约束的组播加入算法(MJAQC),该算法引入了QoS参数不仅可以满足应用对服务质量的要求,而且减小了探针消息的洪泛范围,减少了探针消息的数量。最后证明了该算法找到的路径满足QoS约束条件。更多还原

【Abstract】 One of multicast key technologies is to construct a multicast tree by group members’implicit joining or explicit joining.Aiming at explicit joining,this paper presents a multicast joining algorithm with QoS constraints.The algorithm introduces QoS parameters which not only satisfies the application requirement for QoS but also reduces the flooding range of the probe message.Finally,this paper proves that the path the algorithm finds satisfies QoS constraints.更多还原
