Abstract :
Many Internet service developers already rely on the Parlay X to integrate telecom services to Internet applications. As a standard telecom gateway, Parlay X must be real-time, reliable and stable. In this paper, we consider the Parlay X and network elements as one system and a closed-queuing network model is proposed which has several characteristics such as finite-source, multiclass services and session-based requests. And then it is simplified to an M/G/1/K+Y/H PS queue model to just analyze the Parlay X gateway. Experiments are conducted on the real Parlay X system, and several metrics are evaluated to improve the system performance. Experimental results indicate that the queuing network model and simplified model captures the performance of Parlay X systems faithfully, and they can play an important role in system bottleneck identification, performance prediction and application configuration.
