The decision to discard or forward a packet is made by a flow control mechanism, upstream from the forwarding engine in the node of a communication network. The forwarding engine includes a switch with mechanism to detect congestion in the switch and return a binary signal B indicating congestion or no congestion. The flow control mechanism uses B and other network related information to generate a probability transmission table against which received packets are tested to determine proactively whether a packet is to be discarded or forwarded.
