Problems solved by technology

A high-speed link will consume more energy and increase the user's use cost. Generally, a 1G link consumes 1-2W more than a 100M link; a 10G link consumes 4-5W more than a 1G link. Considering data The number of ports is huge, and the existing technology wastes a lot of energy

Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The link rate adjustment method according to Embodiment 1 of the present invention is as follows: figure 1 shown, including:

[0021] S101. Compare the current link data traffic with the rate adjustment threshold corresponding to the current rate level;

[0022] S102. According to the comparison result, it is determined that the current link rate needs to be adjusted, and then the link rate level to be adjusted is selected fro...

Abstract

The embodiment of the invention discloses a link speed regulation method and a device thereof, wherein the link speed regulation method comprises the following steps: the current link flow is compared with a speed regulation threshold corresponding to a current speed grade; if determination is made that the current link speed needs regulation according to a comparison result, a link speed grade to be regulated is selected from alternate speed grades and a speed regulation starting message which comprises the link speed grade to be regulated is transmitted; and a device receiving the starting message regulates the link speed to the link speed grade to be regulated. The technical proposal compares the current link data flow with the speed regulation threshold corresponding to the current speed grade, selects the link speed grade to be regulated, and regulates the link speed to the link speed grade to be regulated so as to cause the link speed to carry out self-adapted regulation on the base of data flow, thus realizing the purpose of saving energy.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a link rate adjustment method and device. Background technique [0002] A data network consists of computers, workstations, switches, routers, and other network devices. These network devices transmit data packets through media such as copper wires or optical fibers. The network port is the access point for these media. The establishment of a data transmission channel between two network device ports through a medium is called establishing a link. The network device sends a series of pulse signals on the port when it is powered on, a management command is issued, or under user intervention, to inform the peer network device of the support it supports. Working mode, and other information for negotiating the handshake mechanism and receiving the response from the peer network device to establish a link. This negotiation mechanism is carried out on the physica...
