摘　　要：分析了移动IPv6协议原理,介绍了协议的不足,提出了新的移动IPv6协议。针对传统移动IPv6协议这一缺点,新的协议采用区域累计使用时间来确定家乡地址、家乡代理,在技术上使用动态缓存表,并采用OPNET仿真软件对新的协议进行了仿真。仿真结果表明:采用新协议时,网络性能得到明显提高,以目标客户机平均响应时间为例,采用老协议时,平均响应时间为0.007 s,而采用新协议时,平均响应时间为0.003 s。Firstly,MIPv6 Protocol is analyzed.And its shortage is introduced.Secondly,the new Protocol is put forward.In order to avoid low network performance,in the new protocol,the region accumulation time is adopted to determine which could be the home address and the home agent,the dynamic buffer table is adopted to achieve that goal.Then,the performance of the new protocol is simulated with OPNET software,which shows the new protocol could enhance the network performance.For example,the average response time of the client object is 0.003 s in the new protocol,but in the old protocol,it is 0.007 s.
