Performance measurement of IP networks using Two-Way Active Measurement Protocol

Abstract

The use of real-time multimedia applications in IP networks is continuously increasing with the services provided by the evolving internet infrastructure. Providing Quality of Service (QoS) is important for service providers in terms of real-time voice and video services to meet users' expectations. For this reason, QoS parameters such as network latency, jitter and packet loss must be accurately and precisely measured. The widely used PING protocol for measuring the specified parameters do not give accurate and precise results at the desired level. In this study, it is proposed to use Two-Way Active Measurement Protocol (TWAMP) for measuring the QoS parameters of the IP network. TWAMP is the latest method to fully deliver performance metrics for IP network infrastructure. According to the active measurement method, round trip delay, jitter and packet loss parameters between two end nodes were measured with TWAMP and PING protocols and analyzed by comparing values. As a result of the study, it has been shown that TWAMP protocol recommended for multimedia communication is suitable for measuring service quality of IP Networks.
