Title: Method for flow controlling ATM traffic

Abstract: Permission based flow control is implemented in a computer network havingat least a downstream, intermediate and upstream network device byreceiving credits at the intermediate network device from the downstreamnetwork device and granting credits from the intermediate network deviceto the upstream network device based at least in part upon the creditsreceived at the intermediate network device from the downstream networkdevice. Credit chaining as described above is employed to permit thegranting of the right to transmit downstream to be predicated upon bufferavailability downstream of the next downstream network device. Via the useof credit chaining, high utilization of network resources is achieved withminimal loss of data traffic.
