Performance Analysis of Cell Rate Monitoring Mechanisms in ATM Systems
Michael Ritter, Phuoc Tran‐Gia · 1995
The control of cell processes plays a central role in ATM network management and strongly influences the overall system overload behavior and the quality of service. One of the crucial control functions is the usage parameter control according to the user-network contract for a connection. Due to the slotted time of the ATM cell process discrete-time models are suited for performance analysis. In this paper we first present queueing models operating in discrete-time for the cell rate monitoring, where arbitrary renewal cell input processes are taken into account. Subsequently cell processes of ON/OFF-type are considered, where the lengths of ON- and OFF-phases can be arbitrarily distributed. Numerical results are discussed aiming the proper choice of the source traffic descriptor parameter values like cell delay variation tolerance, sustainable cell rate and burst tolerance for different cell process characteristics to be enforced.
