Simulasi Pengukuran Intrafairness Dan Interfairness Protokol-protokol Stream Control Transmission Protocol (Sctp) Dan Transmission Control Protocol (Tcp) Pada Jaringan Unicast

摘要

This paper elaborates the performance analysis of a unicast network when two protocols, SCTP (Stream ControlTransmission Protocol) and TCP (Transmission Control Protocol) coexist in the network. These two protocols are testedusing File Transfer Protocol (FTP) and Constant Bit Rate (CBR) based traffic. From the simulations, it could beconcluded that SCTP could achieve better throughput compared to TCP in both FTP and CBR based traffic, withsufficiently high fairness index of both intrafairness and interfairness. The increase of simulation time yields to theincrease and relatively stable network performance. The increase of the number of sessions of small bandwidthapplications resulted in the increase of troughput and link utilization. The simulations show that implementation ofSCTP and TCP in a unicast network generally could be done without having to degrade the network performance, withrelatively high fairness index, over 0.85 for various traffic variations.
