ABSTRACT:
A system and method for limiting congestion in a network is disclosed. The system includes exchanging data packets through a virtual circuit in a network of links and switches. The system includes at least one switch having a queue within the virtual circuit. The system also includes a message received at the network switches when the queue is congested. The message is propagated through the network. The system also includes an ingress switch having a graceful discard state that responds to the message. The ingress switch discards the data packets that exceed the capacity of the virtual circuit in accordance with the graceful discard state.
