结合移动 IP协议 ( MIP)与资源预留协议 ( RSVP)以达到保证 Internet移动接入中的实时多媒体业务的服务质量 .提出了一种改进的策略 ,对 MIP和 RSVP进行了修改 ,在 MIP中增加了查询和查询应答两个报文来避免三角路由 ,并通过修改 RSVP协议 ,使资源预留可以顺利进行 .同时利用绑定刷新报文中的一个保留比特 ,当移动主机从一个网络移动到另一个网络中时 ,能够快速触发发送 PATH报文 ,保证切换的快速平滑 .最后通过协议分析 ,证明了这种改进的策略的有效性 Combined with Mobile IP Protocol (MIP) and Resource Reservation Protocol (RSVP) to guarantee the quality of service of real-time multimedia services in Internet mobile access.An improved strategy is proposed to modify MIP and RSVP in MIP Increase the query and query response two packets to avoid triangular routing, and by modifying the RSVP protocol, so that the resource reservation can be carried out smoothly.At the same time use a binding refresh message in a reserved bit, when the mobile host moves from a network to Another network can quickly trigger the sending of PATH packets to ensure fast and smooth switching.Finally, through the protocol analysis, we prove the effectiveness of this improved strategy
