A system for congestion control of traffic in a network that uses Transmission Control Protocol (TCP) includes a plurality of TCP congestion control programs having one or more parameters, a plurality of TCP congestion control units running the TCP congestion control programs, and a TCP mapper adapted to map incoming TCP traffic flow from a plurality of incoming TCP traffic flows to the TCP congestion control units based on at least one of (a) the type of application program from which the incoming TCP traffic flow originated (b) the type of network for which the incoming TCP traffic flow is destined, (c) parameters related to network performance (d) network constraints (e) source of the incoming TCP traffic flow, and (f) destination of the incoming TCP traffic flow.
