Title: Stability of rate-based congestion control algorithm for ABR service class in ATM networks
Abstract: A rate-based congestion control algorithm is a feedback-based flow control mechanism for ABR (available bit rate) service class, which is suitable for data transfer applications. The rate-based congestion control algorithm dynamically regulates a cell transmission rate of a source end system according to feedback information from the network. An appropriate choice of control parameters can lead to effective use of network resources. However, once it fails, the rate-based congestion control unexpectedly exhibits unstable operation under some parameter settings, which leads to dramatic degradation of the performance. We investigate causes of unstable operation and performance degradation of the rate-based congestion control. We then propose an improvement in the existing rate-based congestion control algorithm. Its effectiveness is demonstrated by providing several simulation experiments.
