GCRA-BASED ARCHITECTURE OF MULTI-CONNECTION SHAPER AND ENFORCER IN MULTISERVICE ATM NETWORKS

Broadband networks are required to support multimedia applications tha t will have stringent requirements in terms of the quality of service. For instance, a video coding scheme has the ability to distinguish a given cell in the same connection as being a high-or low-priority cell by approprite packetization. Thus, the design of a multi-connection s haper and enforcer architecture which deals with different traffic par ameters and cell priorities is important. In this paper, we propose al gorithms and the architecture of a GCRA-based multiple-connection prio ritized traffic shaper and enforcer. Simulation results reveal that th e GCRA scheme is more suitable for shaping and UPC functions than conv entional leaky-bucket schemes. (C) 1997 Elsevier Science B.V.
