The next generation high speed networks which are characterized by large bandwidth propagation delay products are expected to support applications with diverse traffic characteristics and Quality of Service (QoS) requirements. Since statistical multiplexing is employed in these networks, congestion control and avoidance mechanisms are required for the delivery of QoS required by various applications.A number of reactive flow control schemes have been developed in the past for best effort applications. It has been well established that these schemes are not effective for networks with large bandwidth propagation delay products as the feedback information generated in the network can be outdated by the time it reaches the sources. In this paper, this problem (referred to as the bandwidth mismatch problem) is investigated and a proactive feedback (PF) based flow control scheme which attempts to eliminate the bandwidth mismatch problem by generating and transmitting early feedback messages is introduced. With cooperation among the network nodes and sources, the PF based flow control scheme can significantly increase the QoS delivered to the best effort applications. In addition to the increased level of delivered QoS, fair rate allocations to the best effort applications are also possible since the efficiency of the scheme becomes independent of the length of the propagation delays, once the bandwidth mismatch is eliminated.
