IP 多播是向组发送信息的有效方式。我们的协议建立在现有静态主机IP单播和组播转发服务之上，以避免移动IP中经常出现的三角路由。仅依靠现有的组播服务模型并在每次组播成员和/或源移动时重建传送树并不总是一个好的解决方案。通过应用双向隧道多播的思想，我们的协议试图向组中的所有其他成员隐藏主机的移动性。因此，组播分发树不会因为成员位置变化而更新。此外，我们的协议具有接近最短的传递路径，如远程订阅协议。我们的协议还可以适应主机移动和移动成员数量的波动（即具有移动性和可扩展性属性）。
IP multicast is an efficient means of sending to a group. Our protocol is built on top of the existing static hosts IP unicast and multicast forwarding services to avoid triangle routing which always occurs in Mobile IP. Relying only on the existing multicast service model and reconstructing the delivery tree every time a multicast member and/or source moves is not always a good solution. By applying the ideas of bi-directional tunneled multicast, our protocol attempts to hide host mobility from all other members of the group. Therefore, the multicast distribution tree will not be updated for the sake of member location change. Furthermore, our protocol has near shortest delivery paths like the remote subscription protocol. Our protocol can also adapt to the fluctuation of both host movement and the number of mobile members (i.e., having mobility and scalability properties).
