Abstract

In this paper, a new congestion control mechanism is introduced for SCTP multi-homing. In multi-homing mode, both primary and secondary paths are used for sending main packets. Congestion on each route can be avoided or can be controlled, based on an Active Queue Management (AQM) method. Also, routers compute probability of congestion for the sources on the paths and then notify them. Then, the sources can adjust their sending rates on each path based on a FSM (Finite State Machine) effectively and if necessary can switch to the alternate path to prevent congestion. Simulations have been conducted with Opnet. The simulation shows that the new method can decrease packet loss and end-to-end delay and increase the amount of transmissions compared with standard SCTP.
