Abstract [en]

Due to the cost-effective solutions provided by Voice over Internet Protocol (VoIP) technology to enterprises and individuals, the growth has been significantly high in this area during the past and current decade. The growing demand has resulted in the escalating number of users who need secure, reliable and efficient communication systems. The deployment of multicore hardware has been solving the computational complexity problems. A multicore hardware/software model for VoIP is the key research area of modern telecommunications. One of the challenges is to design and implement a Quality of Service (QoS) benchmark module for multicore VoIP client and server environment. To achieve this we need a benchmarking module to quantitatively analyze QoS parameters namely delay and packet loss, and to further analyze these parameters with security overhead. In this project we have designed and implemented a prototype for a customized network traffic generator called SQgen, keeping in consideration the parallel nature of hardware and software in VoIP communication.

The research focus area is to test the performance of signaling protocol for call set up process. Session Initiation Protocol (SIP) is widely deployed protocol for call establishment, maintenance and termination in VoIP, and we measure the performance of an open source implementation of SIP. Using SQgen, a series of stress tests are performed in different network scenarios to analyze the performance, and investigate the reasons for delays in different parts of the call setup process.
