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. This paper work consists of creating a VoIP network and testing for its known faults. Through this paper, we get a better understanding of the underlying layers of the network and see if and where improvements can be made. In implementation stage the Real-time Transport Protocol (RTP) packets for VoIP applications had been sent and compared with TCP/UDP packets to obtain results which are mainly related to Quality of Service (QoS) factors. The attained result approved that RTP consider to be better 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, we find that, UDP/RTP are more balance and prefer than TCP in real-time applications such as VoIP.
