DESCRIPTION
In this paper, a new OCCEM congestion control mechanism is introduced in multi-homing mode. Congestion ineach 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. Therefore, thesources can adjust their sending rates on each path effectively and if necessary, can switch to an alternate path toprevent congestion. Simulations have been conducted with Opnet linked with NS2. The simulation shows thatthe new method can decrease packet loss, increase the amount of transmissions and stabilize queue length, ascompared with standard OCCEM.
