A congestion control mechanism supporting QoS requirements

Most of the existing congestion control works are suitable for the best effort flows, but not for the flows with quality of service (QoS) requirements. In this paper, by adopting equation-based congestion control (EBRC) for differentiated services instead of traditional TCP congestion control for best-effort service, a new congestion control mechanism supporting QoS requirements can be achieved. Three parts which the mechanism consists of are sender functionality, packet loss control mechanism in routers and receiver functionality. The details of design and implementation within this mechanism are investigated.
