Interface rate control method and device based on Ethernet

Abstract

The invention relates to an Ethernet-based interface rate control method and an Ethernet-based interface rate control device. The Ethernet-based interface rate control method comprises the steps of: judging whether a node where a current interface locates is a slave node after starting a process; if so, controlling corresponding function modules to carrying out interface rate parameter configuration and resetting process and message processing according to a preset rate configuration mode and a corresponding clock strategy, and judging whether the rate configuration mode is completed or not according to signals fed back by the corresponding function modules; and reporting a rate configuration result to a CPU. According to the Ethernet-based interface rate control method and the Ethernet-based interface rate control device, an interface compatible with multiple rates can be established on programmable logic, and the interface can adopt the appropriate rate for network communication according to different network environment rates, thereby solving the equipment self-adaptive problem in the network environment at the multiple rates, reducing cost and risk of version upgrade and maintenance, reducing the dependence on the CPU, and improving the processing capability of the entire system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a programmable logic Ethernet-based interface rate control method and device. Background technique [0002] The Ethernet networking technology is the most common baseband LAN networking technology used in existing LANs, and is widely used in LAN communication devices. In traditional high-speed Ethernet communication equipment, according to different networking conditions, interfaces with a rate of 1000Mb / s and 100Mb / s are generally used, and they all conform to the IEEE 802.3 standard. However, with the development of the communication industry, especially the arrival of the 4G era, higher requirements are put forward for the data interface rate, so the supplementary standard IEEE 802.3ae is derived from the IEEE 802.3 standard, in which the rate is defined as 10Gb / s Ethernet interface, and gradually applied to the interface of communication equipment. It is foreseeable...
