Performance Evaluation of SCTP and TCP in Voice Communication

The number of Internet users is increasing quickly with the transmission of voice over IP. Therefore provision of fast transmission without jitter and delay is the fundamental aspect of voice communication. This study evaluates the performance of SCTP and TCP in transmission of voice packets. Generally, when packets are arrived at destination, these are probably affected by jitter. Many researchers have applied different techniques on them in the buffer to minimize jitter. In this study, an algorithm is applied on packets in the buffer for end-to-end delay and jitter management. The paper presents two topologies to analyze the performance of TCP and SCTP in case of delay and jitter. The functionality of these protocols is simulated and tested in NS2. The results show a good increase in throughput and delay and jitter minimization.
