Abstract

In this paper, we study a cell spacing method of congestion control in ATM networks. The idea is to smooth the input flows at the access nodes in order to prevent cells from entering the network in a manner that could affect its performance. We consider a queueing system that prevents any two successive cells from being transmitted within a time shorter than a variable value. This device does not interfere with cells that find the queue empty and arrive a sufficiently long time after the last departure but spaces apart those which arrive too closely to each other. We analyze the statistical properties of the output traffic of such a cell spacer when the input process is modeled as a Compound-MMPP.
