A Performance Benchmark of a Multimedia Service Delivery Framework

The IP Multimedia Subsystem is a control overlay network that enables the delivery of multimedia services to end subscribers. One of the core steps towards the optimization of an IMS deployment consists of verifying that the involved resources deliver the desired performance when the system is operating under stress conditions. With this goal in mind, this paper presents an IMS performance evaluation based on the IMS/NGN Performance Benchmark specification from ETSI, using well-known open source software reference implementations and state-of-the-art analyzing tools for collecting the related measurements.
