Evaluation of Service of Quality of Voice over Internet Protocol

Abstract

In recent years, Voice over IP (VoIP) has gained a lot of popularity and become an industry favorite over Public Switching Telephone Networks (PSTN) with regards to voice communication. The project consists of creating a VoIP network and testing for its known faults. Through this project wanted to get a better understanding of the underlying layers of the network and see if and where improvements can be made. In implementation stage the RTP packets for VOIP applications had been sent and compared with TCP/UDP packets to obtain results which are mainly related to QoS factors. The attained result approved that RTP consider to be batter to reduce a packet loss than UDP, and also approved that UDP/RTP are most reliable because they had a very small delay and jitter in contrast with TCP. Hence, find that, UDP/RTP are more balance and prefer than TCP in real-time applications such as VOIP.
