Performance Comparison of TCP, UDP and SCTP in a Wired Network

Stream Control Transmission Protocol (SCTP) is a transport protocol, like TCP and UDP. SCTP provides different services like connection orientation, reliability, end-to-end communication, flow control and congestion control. SCTP has unique quality such as multi-streaming and multi-homing which are not present in traditional transport protocols. The current transport protocols are not enough to meet the requirements of multimedia. New protocols like SCTP are being developed in order to cope up with emerging applications like multimedia. In this paper performance comparison of TCP, UDP and SCTP is done in a wired network. In order to identify the limitations of the three transport protocols in wired network and to understand the scope for improvement is the main purpose of this paper. The performance is analyzed using the metrics Packet Loss Rate (PLR), Jitter, End-to-End Delay (ETE Delay), Packet Delivery Ratio (PDR), Throughput and Fairness. Ns-2.35 is used as a simulator.
