Abstract
There has been a strong focus on the evaluation of Quality of Service (QoS) and multimedia transmission over protocols of internet protocol (IP). The main goal of this paper is to evaluate the performance of QoS in real implementation, also a comparison of an appropriate video and voice (CODECS) over IP schemes depending on the SIP and IAX2 protocols based on the Asterisk PBX server(s), an open source communication platform. The network was implemented within various private networks, such as Wire and Wi-Fi, which serves as a local exchange for placing various calls. Quality has been evaluated based on some QoS parameters such as bandwidth, jitter and delay to investigate the performance of different codecs in video and voice over IP (VVoIP) network. The VVoIP codecs used in the measurements are: G.711 (ulaw&alaw), GSM, G.722, Speex, H.263, H.264, H.261 and H.263P. Evaluation of performance results will give network Planners and Multimedia protocols developers an opportunity to select the codec for VVoIP performance enhancement, which can lead to improved customer satisfaction.
