Abstract

The invention discloses a message processing method and system based on a delay mark ECN. The method comprises the following steps: obtaining first time T1 for receiving a message and second time T2 for sending the message; obtaining the latency of the message, wherein the latency is equal to T2-T1; configuring a latency grade according to the latency range, and obtaining a corresponding latency grade according to the latency of the message; and judging whether the ECN is marked or not according to the latency level of the message. According to the method, the latency is divided according to the grades, and the ECN is marked according to the latency grades, so that the utilization rate of a network can be improved, and the method for preventing congestion and avoiding oscillation is more diversified.

Description

technical field [0001] The invention belongs to the technical field of message transmission, and in particular relates to a message processing method and system based on a delay mark ECN. Background technique [0002] RFC3168 defines an effective way to solve the congestion problem, see figure 1 As shown, TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) uses unused fields in the packet header to support ECN (Explicit Congestion Notification, explicit congestion notification). [0003] On the intermediate device: [0004] When congestion occurs, for packets with ECN=2b’00 (2b means binary), go through the original ordinary non-ECN process, that is, perform RED (Random Early Detection) packet loss; [0005] When congestion occurs, the messages for ECN=2b’01 or 2b’10 need to be modified to ECN=2b’11, and the forwarding process continues; [0006] When congestion occurs, the packets with ECN=2b'11 need to be forwarded c...
