Abstract
Description
Claims (3)
- ATM(Asynchronous Transfer Mode)과 Non-ATM간의 접속 구간에서 혼잡이 발생하여 버퍼의 최소 임계치 및 최대 임계치 사이에 평균 큐의 크기가 존재할 경우에 해당 접속 구간에서 ECN(Explicit Congestion Notification) 알고리즘을 역방향으로 적용하여 해당 혼잡 발생을 TCP(Transmission Control Protocol) 소스가 바로 인식해 혼잡 회피 처리를 수행하도록 하는 것을 특징으로 하는 티씨피 혼잡 제어 방법.
- ATM과 Non-ATM간의 접속 구간에서의 버퍼에 패킷이 도착하는 경우에 평균 큐의 크기를 계산해 크기가 최소 임계치와 최대 임계치 사이에 존재하는지를 확인하는 과정과;상기 계산된 평균 큐의 크기 및 가중치에 의해 결정되는 확률에 따라서 상기 도착한 패킷에 마킹해 TCP 소스에 전달될 응답 패킷을 생성하는 과정과;상기 TCP 소스에서 상기 응답 패킷을 수신받아 혼잡 발생을 인식하여 송신 윈도우 사이즈를 감소시켜 혼잡 회피 처리를 수행하는 과정을 포함하여 이루어진 것을 특징으로 하는 티씨피 혼잡 제어 방법.
- 제2항에 있어서,상기 응답 패킷 생성 과정은 상기 TCP 소스에 전송될 응답 신호가 있는지를 확인하는 단계와;상기 응답 신호가 있는 경우에 TCP 헤더에 할당된 예비 필드의 ECN 에코 플래그를 세팅하는 단계와;상기 세팅된 응답 패킷을 상기 TCP 소스에 전송하는 단계를 포함하여 이루어진 것을 특징으로 하는 티씨피 혼잡 제어 방법.
