Abstract

A flow control method and apparatus for controlling flow through an output link in a communication network modifies a prior art Phantom flow control method by calculating the maximum allowable cell rate as a function of the number of active flows through the output link. To accomplish this, the method and apparatus calculates alpha smoothing parameters as a function of the number of virtual channels flowing through the output link. The method and apparatus improves the stability of the Phantom flow control method, and also enables it to be used with less costly network switches, such as shared memory switches.
