Abstract :
Queueing disciplines at asynchronous transfer mode (ATM) switching nodes handling various kinds of real-time traffic are investigated. ATM can support various new services including voice, data, and video. However, the characteristics of superposed traffic carried by ATM are not known, and a control effective for a versatile arrival process is required. The optimal discipline which minimizes the number of cells being delayed beyond the specified maximum allowable time, and thus being discarded is derived, without assumptions on the arrival process of cells and buffer management schemes. Also discussed is implementation of the optimal discipline and a method of satisfying cell loss probability requirements of individual classes
