Throughput Analysis of SCTP over a Multi-homed Association

Stream Control Transmission Protocol (SCTP) is an emerging transport protocol for sending data from one point to another over the Internet. The two major new capabilities that are designed into SCTP are the support for multi-homed hosts and the support for multiple streams in a single SCTP association. The purpose of this paper is to investigate the performance of SCTP, measured in terms of association throughput. We analyze the throughput for two experimental scenarios: 1. Transmission of data chunks with different sizes of payload in network stable state (no packet loss). 2. Transmission of data chunks with different sizes of payload in packet loss environment. We have shown the impact of data chunk transmissions with different sizes of payload on the throughput of a multi-homed SCTP association. Our experimental results and analysis show that SCTP provides better throughput in the case of large payload data chunks transmission in both network stable state and packet loss environment.
