Flow control in asynchronous networks

摘要

In a method of controlling the flow of cells in an asynchronous network, cell flow in upstream and downstream portions of a virtual connection is controlled by respective upstream and downstream control loops employing resource management (RM) cells. The degree of backward coupling between the two control loops is adjusted to optimize network stability and response time by filtering the downstream Backward Explicit Rate or monitoring the degree of congestion at the boundary between the control loops. <IMAGE>
