A rate-based switch algorithm with delay adjustment for ABR traffic to achieve max-min fairness

Wales Kin Fai Wong, Danny H. K. Tsang · 1995

All the current rate-based proposals suggest to adjust the source transmission rate based on the received RM cell immediately. However, this approach may lead to overloading of the bottleneck switch. We propose that the adjustment should be delayed. The amount of delay depends on the source-to-bottleneck separations of different connections, which can be obtained during the call setup. Based on our Max-Min scheme [2] that can rapidly achieve the fair share allocation, a new rate-based switch mechanism is proposed to take into account of the delay. With this, overloading of the bottleneck switch due to the different source-to-bottleneck separations can be avoided and thus, the peak queue length of the bottleneck switch can be minimized. Technical Area Congestion Control 1 Problem Definition Under the current rate-based flow control framework suggested by ATM Forum, the switches calculate the proper submission rates for different VCs passing through it. This information is se...
