Network equipment energy-saving method supporting frequency-modulation and consumption reduction

Abstract

The invention relates to a network equipment energy-saving method supporting frequency-modulation and consumption reduction. The method includes the following steps that firstly, a function module is considered as a unit, and the function modules are classified into a frequency-modulation region or a non-frequency-modulation region according to whether the function modules have frequency-modulation capacity or not; secondly, a clock domain crossing interface is designed, the asynchronous clock communication among the frequency-modulation modules and among the frequency-modulation modules and the non-frequency-modulation modules is finished; finally, a frequency arbiter makes a frequency-modulation decision according to the using condition and the multi-threshold frequency-modulation strategy of the clock domain crossing interface and gives out a corresponding clock signal or a control signal to achieve frequency switching. By means of the method, the working frequency of the function module inside a network device can be adjusted according to the network load, the electricity consumption of the network device can be reduced greatly without affecting the user experience, the applicability of the network environment is good, the requirements of current network operators, equipment firms and users for the functions of energy conservation and emission reduction of the network device are met, the economical benefits is remarkable, and the application prospects are wide.

Description

Technical field: [0001] The invention relates to an energy-saving method for network equipment, in particular to an energy-saving method for network equipment supporting frequency modulation and consumption reduction, and belongs to the technical field of energy-saving network equipment. Background technique [0002] With the rapid development of the number of users and bandwidth demand, Internet power consumption and corresponding carbon emissions also increase rapidly. It is estimated that in 2008, China's three major telecom operators consumed 24.1 billion kilowatt-hours of electricity, and the electricity bill in that year was as high as 12.1 billion yuan, with an annual growth rate of 5%. Such a severe energy consumption situation and its development trend are largely due to the large-scale deployment of network equipment. According to data released by GeSI, the number of routers deployed on the Internet reached 67 million in 2002 and will reach 898 million in 2020. C...
