4CP: Competitive and Considerate Congestion Control Protocol

PublisherMicrosoft
Format267.1KB PDFDate added01 Aug 2006

This paper presents a first practical packet-level window-based congestion controller (4CP) that implements farsighted strategy, which was introduced and shown to be optimal for sources that value large long-run average throughput and are indifferent to sporadic throughput degradations. The target loss probability is adapted very slowly so that the 4CP source verifies a given (TCP) loss-throughput formula over large timescale. The send rate is reduced to (virtually) zero in a controlled manner only during bad congestion phases, and not under full control of other (TCP) transfers, as it is the case with prior low-priority service emulators.
