링크 효율성에 영향을 주지 않고 인터넷을 통해 서로 다른 연결 간에 대역폭을 공정하게 할당하는 것은 네트워크 성능 향상 분야에서 어려운 문제였습니다. 이를 위해서는 혼잡 신호가 필수적입니다. 기존 TCP는 패킷 손실을 암시적인 정체 표시로 사용합니다. 더 빠른 혼잡 복구를 통해 네트워크 성능을 향상시키기 위해 TCP에 대한 몇 가지 향상된 기능이 제안되었습니다. 그러나 패킷 손실로 인해 TCP 굿풋(goodput)이 감소하고 큰 지연이 추가됩니다. 또한 각 연결에서 얻은 대역폭 점유율의 차이가 허용할 수 없을 정도로 커질 수 있습니다. 이와 반대로 명시적 혼잡 알림(ECN)은 실제로 혼잡이 발생하기 전에 명시적으로 이를 알려줍니다. 따라서 ECN은 보다 빠른 혼잡 감지를 촉진하고 네트워크 성능 향상에 기여합니다. 이 문서에서는 여러 TCP 향상 체계와 함께 다양한 ECN 전략을 사용하는 경우 성능에 미치는 영향을 고려합니다. 또한 새로운 ECN 패킷 표시 전략 FIM을 소개하고 다양한 TCP 개선 사항과 함께 배포에 대한 상대적인 성능과 적합성을 평가합니다. 시뮬레이션 결과는 링크 효율성을 저해하지 않고 최고의 공정성을 제공함으로써 다양한 TCP 향상 방식을 사용하는 기존의 다른 마킹 전략에 비해 FIM의 우월성을 보여줍니다. 또한 FIM은 다른 전략보다 더 일관된 지연 한계를 유지하므로 실제 목적으로 적용하는 데 더 적합합니다.

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.
