摘要
多网络覆盖的无线网络环境下由于存在路径选择和切换等机制,对于移动流媒体的传输方案有更高的要求,mSCTP协议是在流媒体控制传输协议SCTP的基础上增加了动态地址配置特性,可在用户移动的同时进行IP地址的动态增加和删减,从而选择最佳的传输路径,现结合mSCTP的动态地址配置特性和SCTP本身具有的多宿特性,提出一种在用户慢移动状态下,针对点播模式的移动流媒体业务的优化传输方案,制定传输路径选择策略,在主路径满足业务要求前提下不进行不必要的路径性能测试与切换,并通过NS2仿真验证。
Transmission scheme for mobile streaming media in multiple network environment has more requirements because of transmission path selection and developed dynamic address configuration based on SCTP protocol, in order to add s covered wireless switch, mSCTP is new IP address or delete invalid IP address, an improved program for mobile streaming media on demand services which based on slow-moving situation is proposed in this paper using the new feature of mSCTP and multi- homed feature of SCTP, and simulated on NS2.
