METHOD AND APPARATUS FOR FRAME RELAY CONGESTION CONTROL INTERWORKING WITH ABR FLOW-CONTROL LOOPS

摘要

In a hybrid network including network segments characterized by Layer 2 data protocols (e.g. frame relay) and ATM network segments with ABR service categories, a method for interworking each network segment's congestion controls provides closed-loop congestion control end-to-end, i.e., across the entire hybrid network. The hybrid network is divided into flow-control segments, and backward congestion notifications are mapped into preceding networks, which improves congestion.
