Abstract

The invention provides a network flow control method, device, system and server. The method includes: receiving an Ethernet data packet, generating a random number corresponding to the Ethernet data packet; determining whether to discard the Ethernet data packet according to the random number and the watermark value, and if it is determined not to discard, then The Ethernet data packet is output to the service processing device of the server; the watermark value is determined according to the difference between the output flow of the Ethernet data packet output to the service processing device and the target flow, and the watermark value is The value range is a subset of the value range of the random number. Through the closed-loop control, the present invention can randomly discard a large number of requests sent by users according to a certain ratio, thereby avoiding the phenomenon that the service capacity of the server may decrease or even collapse due to overload.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a network flow control method, device, system and server. Background technique [0002] Ethernet is the most common communication protocol standard used by existing LANs today. Whether it is from the demand side or the supply side, the overall network is moving towards broadband, which gives Ethernet a good room for development. From a technical point of view, in the past 20 years, Ethernet bandwidth has grown from 10M, 100M, and 1000M to 10M in 2002, and now even 40M and 100M are in the research and discussion stage, which makes Ethernet Network technology has good scalability; from the application point of view, Ethernet is not only limited to the application of LAN, 10 Gigabit Ethernet further extends Ethernet to the application of wide area network, and cooperates with the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronic...
