In ATM networks, a Usage Parameter Control (UPC) strategy has to regulate incoming traffic according to the characteristics of the sources declared at call set-up. The Generic Cell Rate Algorithm (GCRA) is recommended by the ATM Forum for use in performing UPC at the User Network Interface (UNI) in ATM networks. In this paper, we study the characteristics of a multiplexer with a sufficiently large buffer in which cell arrivals are policed by a GCRA enforcer before entering the system. In addition to mean rate, the peak rate and cell delay variation (CDV) are also taken into consideration for each GCRA enforcer. Based on the the worst arrival pattern (or the worst output pattern from the GCRA enforcer), we derive the upper bound of the waiting time expressed as a function of the GCRA parameters and the number of sources.
