Performance analysis of the congestion control scheme in signaling system no.7

Abstract

The performance is analyzed of the congestion control scheme in signaling system no.7 (SS7). Unlike many other congestion control schemes used in data networks, a threshold control along with a choking mechanism is used in this scheme. Two analytic models are developed that are used to study the steady-state performance and the triggering behavior of the congestion control scheme. Both models are amenable to simple solution techniques. Numerical examples are provided that reveal the dynamics of the congestion control scheme with respect to various control parameters. From these results, a set of guidelines is elaborated for the determination of congestion control parameters that will result in good performance of the signaling network.<>
