Controlling congestion in B-ISDN/ATM: issues and strategies

The high-level goals of a congestion control architecture are outlined. The controls are discussed in detail, focusing on the set of controls exercised by the network and the functionality needed at the network access and in the internal network elements. The end system controls are discussed only to the extent that they can benefit from the available network controls. The motivation for the suggested controls is discussed by describing their use for selected traffic types. Example traffic types and the use of some of the controls to support these traffic types in an integrated environment are examined.<>
