Abstract:

A facility is provided in an ATM network to track whether data traffic from a source is being admitted into the network in accord with associated traffic parameters, which control such admission and dynamically change based on the level of congestion along an associated connection carrying such data. Such level of congestion is determined by launching a particular type of cell over the connection and waiting to see if the destination point of the connection and intermediate points thereof return the cell to the sender, thereby indicating that the route of the connection is not congested. If the cell is not returned, then the facility concludes that the route is congested.
