Abstract
A system and process are provided for controlling congestion at a node of an asynchronous transfer mode (ATM) communications network. The process and system utilize fuzzy logic in determining whether or not to 'admit,' i.e., allocate a virtual channel (VC) for, new communications (or calls) to the node. Fuzzy logic is also use to control the rate cells are transmitted to the node for communications already 'admitted,' i.e., for which a VC has already been allocated. The fuzzy logic rules for bandwidth estimation in admission control may be developed from an 'equivalent capacity' model. The fuzzy logic rules for adjusting cell transmission rates may be developed from a 'two-threshold' congestion control model.
