Service performance analysis on SIP powered multimedia networks

Abstract

This paper proposes to establish a simple Web-based service performance tool that simulates selected normal and abnormal operations of an SIP powered network. Based on this tool, a variety of multimedia service traffic is supported. The tool is used to analyze the service performance of respective network elements in a simulated SIP environment, where traffic of different service types and management procedures is generated under different network configurations and scenario setups. The analytical study supports one service types initially: VoIP (voice over Internet protocol), and is extended to study other service types such as voice-band data call and fax. The user can input the desired service types, traffic volumes and distributions, and configure the service proceeding scenario interactively through the friendly input format from any client. The service performance study under this simulated network is especially useful to the service providers who are currently offering Internet-based services or have been planning new services aggressively. Service impacts due to resource bottleneck are noticed by active operators so improvement or enhancement can be implemented in time before problems start developing. The operation of service network can be simulated under a controlled circumstance so new services can be introduced with the required support capacity specified to reflect the quality level the service network can offer.
