Abstract
The explicit rate flow control mechanisms for ABR service are used to share the available bandwidth of a bottleneck link fairly and reasonably among many competitive users and to maintain the buffer queue length of a bottleneck switch connected to the link at a desired level in order to avoid and control congestion in ATM networks. However, designing effective flow control mechanisms for the service is known to be difficult because of the variety of dynamic parameters involved such as available link bandwidth, burst of the traffic, the distances between ABR sources and switches. In this paper, we present a fuzzy explicit rate flow control mechanism for ABR service. The mechanism has a simple structure and is robust in the sense that the mechanism's stability is not sensitive to the change in the number of active virtual connections (VCs). Many simulations show that this mechanism can not only effectively avoid network congestion, but also ensure fair share of the bandwidth for all active VCs regardless of the number of hops they traverse. Additionally, it has the advantages of fast convergence, low oscillation, and high link bandwidth utilization.关键词
