AI Technical Summary

Problems solved by technology

[0018] In most switching systems, the Ethernet interface cannot withstand the bombardment of large-flow data, especially the short packets of large-flow, and the interruption of sending and receiving of a large amount of data generated by it will quickly make the switching system run slowly or even hang the entire system

Abstract

The invention provides an Ethernet flow control method, a device and a network device. The method comprises the following steps: periodically carrying out real-time statistics on received and sent data traffic; regulating the optimum throughput according to a statistical result; and carrying out flow control on a sending end and a receiving end according to the optimum throughput. The invention carries out real-time monitoring on the data traffic received and sent by an Ethernet port and regulates the optimum throughput in real time, thereby carrying out flow control on the received and sent data traffic, effectively controlling the total throughput of a system and ensuring that the system stably works under the greatest possible throughput.

Description

technical field [0001] The invention relates to an Ethernet flow control method, device and network equipment, belonging to the technical field of data communication. Background technique [0002] Some concepts involved in the present invention are described below: [0003] 1. Processor [0004] The processor is what we call the central processing unit (Central Processing Unit, referred to as CPU), its main function is to perform arithmetic and logic operations, the internal structure can be roughly divided into several parts such as control unit, arithmetic logic unit and storage unit. According to the word length of the processed information, it can be divided into: 8-bit processor, 16-bit processor, 32-bit processor and 64-bit processor. Most of the switching and routing systems are designed and implemented using communication processors. [0005] 2. Bus [0006] From the perspective of computer architecture, a bus is a transmission line for information shared between...
