Abstract
System for obtaining an efficient and scaleable flow control in a large packet switched network including ingress termination boards (B1″) linked to egress termination boards (B4″) by means of virtual ingress to egress flow control links through a switch core.The flow control transmission link between a port of an ingress termination board and a port of an egress termination board comprises at least two virtual ingress to egress flow controlled traffic pipes (VIEP″a, VIEP″b), one pipe handling all the traffic between the two ports which is going towards communication channels for which no congestion is detected at the level of the egress termination board, the other pipe handling all the traffic going towards communication channels for which congestion is detected.
