| 摘 要： | 提出一种基于mSCTP协议的传输层连接管理机制CoMa-mSCTP，实现带宽聚合与移动性支持的结合。定义了其中的关键路径管理功能模块，介绍了路径切换过程，并提出一种基于广义路径定义的传输路径子集选择策略。对CoMa-mSCTP的带宽聚合效果、传输路径子集选择策略效果和移动性支持能力分别进行了仿真实验。仿真结果表明，CoMa-mSCTP能够实现带宽聚合与移动性的有效结合，基于应用特性的传输路径子集选择策略具有明显的性能优势。

| Abstract: | An mSCTP-based connectivity management scheme, CoMa-mSCTP, was proposed to realize the integration of bandwidth aggregation and mobility supporting at transport layer. The major path management functions were defined and the path handoff procedure was introduced. A transport path subset selection policy based on wide-sense path definition was proposed. The simulations on the effect of the throughput improvement, the path subset selection policy and the mobility supporting were complemented respectively. The simulation results show that CoMa-mSCTP can realize efficient integration of bandwidth aggregation and mobility and the application-based path subset selection policy has apparent performance advantages. |
