一种新的移动IPv6绑定更新机制

A New Binding Update Mechanism for Mobile IPv6

移动IPv6中提供了一种路由优化机制,允许通信节点向移动节点直接发送路由数据包,但移动节点必须先要向通信节点发送绑定更新.在发送绑定更新之前的返回路由可达过程中,其测试消息的发送过程将会带来一定的时延和数据流量的增加,同时也存在一些安全性问题.提出了一种绑定更新机制,通过减少信令发送和引入数字签名,使其在效率和安全性方面得到了显著改善.

Mobile IPv6 provides a mechanism of routing optimization that allows communications nodes to directly route data packets to mobile nodes, but mobile nodes must send binding updates to communications nodes in advance. Before sending binding updates, in the return routability procedure, a certain delay and the increase of data traffic will arise in process of sending testi some safety problems. The mechanism of binding updates proposed ciency and safety by reducing signal sending and introducing digital ng messages, while there may be also by this paper can greatly improve effisignature.
