摘要
研究了任意源组播模型中接收者加入组播组和组播源发送组播数据的流程,分析了在任意源组播应用中可能需要实施的访问控制类型。针对每一种访问控制类型,在组播协议中设计了具体的访问控制实现机制。在OPNET Modeler软件上根据实现机制进行进程及节点建模,并搭建仿真环境对机制的有效性进行了验证。
This paper studies the processing flow of a receiver joining a group and a sender sending data to a group in an any-source multicast（ASM） model.All probable access control types that may need to be implemented in ASM applications are analyzed.A specific mechanism is designed for implementation of each access control type.OPNET Modeler software is used to model the implementation mechanisms.Finally,a simulation environment is established to verify the effectiveness of the mechanisms.
