As ISDN frame-relay networks do not have all the control capabilities of X.25-based networks, effective control strategies need to be developed to ensure efficient and high performance operation. In this paper, we are concerned with the congestion avoidance strategy. We propose a new concept for variable window congestion avoidance strategies consisting of the definition, at no additional overhead cost, of a third network operation mode (the two others being the congested and uncongested modes). Two methods of defining this additional mode are addressed. The proposed scheme is very practical. It can easily be applied in a real network, and does not suffer from stability problems. Also, it is not vulnerable (up to a certain degree) to unreliable and inaccurate measurements of end-to-end packet delays. We compare the performance of this new scheme with similar schemes discussed in the literature. The proposed scheme, being delay-oriented, has a lower delay and a higher power (= Throughput/Delay) than all the recently reported schemes.
