Abstract
In a connection oriented communications network such as an asynchronous transfer mode (ATM) network, virtual circuit (VC) connections are aggregated onto virtual path (VP) connections to simplify traffic management through core switching elements. This invention provides a system and a method of introducing network level fairness between VP connections in the core. Resource management (RM) cells are used to import relevant traffic weighting parameters from the VC/VP aggregation point to the VP switching element. The weighting parameters are used by a queuing scheme at each switching function to introduce a fairness level component to each VP.
