Abstract
A network for ATM signals includes source end systems SES,SES,connected by a permanent virtual connection PVC,through switch SW,SWN. Dynamic bandwidth controllers DBC,DBC,operate as virtual source/virtual destinations. The individual switches, such as switch SW,have associated rate controllers RC,which determine the available bandwidth for the signal path PVC,Dynamic bandwidth controller DBC,interrogates the rate controller RC,RC,using resource management RM signals which cascade from switching node to switching node along the path in a forward direction and then in a backward direction. The DBC's communicate with the SES's using RM signals which may be of a different format to the RM signals which pass from switching node to switching node.
