A Workload Model for Benchmarking IMS Core Networks

Performance benchmarking is a method to assess performance characteristics of various systems across different chip/system architectures under realistic conditions, to collect measurements such as success/fail rate, response times or round-trip delays and to identify problems for scalability or usability aspects under heavy load. In this paper, a benchmarking workload model for IP multimedia subsystem (IMS) is introduced. Our performance methodology is based on simulation of real world traffic conditions by defining a set of requirements which best characterize a population of UEs (user equipment).
