Congestion management in managed packet-switched networks

摘要

A packet switched network includes a network manager for managing resources on the network and a plurality of switch nodes. A congestion indicator threshold is (Cir) for each resource at each switch node and congestion event indicator is forwarded to the network manager immediately upon the congestion level of a monitored resource exceeding its congestion threshold. A congestion status for the monitored resources of each switch node is maintained by the network manager.
