Menyediakan peruntukan lebar jalur yang saksama antara sambungan yang berbeza melalui Internet tanpa menjejaskan kecekapan pautan telah menjadi isu yang mencabar dalam bidang peningkatan prestasi rangkaian. Isyarat kesesakan adalah penting untuk tujuan tersebut. TCP konvensional menggunakan kehilangan paket sebagai petunjuk tersirat kesesakan. Beberapa penambahbaikan kepada TCP telah dicadangkan untuk pemulihan kesesakan yang lebih cepat dan dengan itu untuk meningkatkan prestasi rangkaian. Walau bagaimanapun, kehilangan paket mengurangkan goodput TCP dan menambah kelewatan yang besar. Juga varians dalam bahagian lebar jalur yang diperolehi oleh setiap sambungan mungkin menjadi sangat tinggi. Sebaliknya, Pemberitahuan Kesesakan Eksplisit (ECN) menunjukkan kesesakan secara eksplisit sebelum ia benar-benar berlaku. Oleh itu, ECN memudahkan pengesanan kesesakan yang lebih pantas dan menyumbang kepada peningkatan prestasi rangkaian. Dalam makalah ini, kami mempertimbangkan implikasi prestasi menggunakan strategi ECN yang berbeza bersama-sama dengan beberapa skim peningkatan TCP. Kami juga memperkenalkan strategi penandaan paket ECN baharu FIM dan menilai prestasi relatif dan kesesuaiannya untuk penggunaan bersama-sama dengan peningkatan TCP yang berbeza. Keputusan simulasi menunjukkan keunggulan FIM berbanding strategi penandaan sedia ada lain dengan skim peningkatan TCP yang berbeza dengan memberikan keadilan terbaik tanpa menghalang kecekapan pautan. Kami juga melihat FIM mengekalkan kelewatan terikat yang lebih konsisten daripada strategi lain dan oleh itu, lebih sesuai untuk digunakan dalam tujuan praktikal.

Abstract: Providing a fair allocation of bandwidth among different connections over the Internet without affecting link efficiency has been a challenging issue in the area of network performance improvement. Congestion signaling is essential for the purpose. Conventional TCP uses packet loss as an implicit indication of congestion. Several enhancements to TCP have been proposed for faster congestion recovery and thus to improve the network performance. However, packet loss reduces TCP goodput and adds large delay. Also the variance in the share of bandwidth obtained by each connection may become unaccepatbly high. To the contrary, Explicit Congestion Notification (ECN) indicates a congestion explicitly before it actually occurs. Therefore, ECN facilitates a faster congestion detection and contributes to the network performance improvement. In this paper, we consider the performance implications of employing different ECN strategies along with several TCP enhancement schemes. We also introduce a new ECN packet marking strategy FIM and evaluate its relative performance and suitability for deployment along with different TCP enhancements. Simulation results show the superiority of FIM over other existing marking strategies with different TCP enhancement schemes by providing the best fairness without hampering link efficiency. We also observe FIM maintains a more consistent delay bound than other strategies and as such, is more suitable for application in practical purposes.
