This paper discusses an optimization-based approach for congestion control together with multipath routing in a TCP/IP network. In recent research we have shown how natural optimization problems for resource allocation can be solved in decentralized way across a network, by traffic sources adapting their rates and routers adapting their traffic splits, all using a common congestion measure. We present here a concrete implementation of such algorithms, based on queueing delay as congestion price. We use TCP-FAST for congestion control, and develop a multipath variant of the distance vector routing protocol RIP. We demonstrate through ns2-simulations the collective behavior of the system, in particular that it reaches the higher transfer rates available through multiple routes.
