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.
