引入区域外地代理移动IP方法以减少需要向位于远程的归属代理注册的频率。在多播组成员频繁改变其位置的环境中，提供支持IP多播的有效系统对于提供移动性支持的系统是一个挑战。此外，敏感应用需要可靠的多播服务，以保证每个预期的接收器接收到每个发送的数据包的副本。我们提出了一个架构，支持IP组播的环境中，移动性支持使用区域外国代理。该方案利用本地注册的固有特性，提高了组播支持的效率。性能方面，如组播数据报延迟，交付成本和鲁棒性进行了分析。仿真结果被用来描述在各种条件下的性能。此外，所提出的方法扩展到支持可靠组播。该方案容忍区域外国代理的故障，并补偿那些数据报未交付由于这种故障和那些由于接收机的移动性。
The regional foreign agent Mobile-IP approach was introduced to reduce the frequency by which registration with the remotely located home agent is needed. Providing an efficient system that support IP multicast, in an environment where the multicast group members frequently change their locations, is a challenge for systems providing mobility support. In addition, sensitive applications require a reliable multicast service such that each intended receiver is guaranteed to receive a copy of each transmitted packet. We propose an architecture that supports IP multicast in an environment where mobility is supported using regional foreign agents. The proposed scheme takes advantage of the inherent characteristics of the local registration to enhance the efficiency of the multicast support. Performance aspects such as multicast datagram delay, delivery cost and robustness are analyzed. Simulation results are used to describe the performance under various conditions. In addition, the proposed approach is extended to support reliable multicast. The proposed scheme tolerates the failure of regional foreign agents, and compensates for those datagrams undelivered due to such failures and for those due to the mobility of the receivers.
