Environmentally-friendly energy-saving network exclusive protection method

Abstract

The invention requests to protect an environmentally-friendly energy-saving network exclusive protection method, which relates to the communication network field. The invention provides the environmentally-friendly energy-saving network exclusive protection method by aiming at the performance defects that an all optical network has more energy consumption and high blocking rate and damage is serious once faults happen, and by aiming at the problem that the traditional environmentally-friendly energy-saving and protection technology is not suitable for a large completely-dynamic high-speed WDM (wavelength division multiplexing) network. A corresponding optical fiber cost factor is determined by the wavelength use situation of a single optical fiber on a link to further determine the link cost factor, and finally, the link cost factor is combined with the corresponding link energy consumption to obtain a link energy consumption weight mode to find an optimal route; finally, wavelength distribution is carried out; the phenomena that overmuch energy is used and an overlong route is formed can be avoided; and meanwhile, each working path can be protected to the maximum degree.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to an energy saving and fault protection method in an optical wavelength division multiplexing network. Background technique [0002] The explosive growth of data services and the high bandwidth consumption of network applications have led to rapid increases in network energy consumption, operating costs, and greenhouse gas emissions. Wavelength Division Multiplexing (WDM) technology is considered to be the mainstream choice of high-speed wide-area backbone network due to its advantages of large transmission capacity, strong application adaptability and easy expansion. WDM technology can multiplex multiple wavelengths on one optical fiber, so that the link can carry a huge amount of information. At the same time, the increase of network bandwidth and switching equipment has brought about two problems: one is the increase of energy consumption. According to statistics, today's...

At the same time, the increase of network bandwidth and switching equipment has brought about two problems: one is the increase of energy consumption

Second, the loss caused by the failure is serious

For large-scale and high-speed WDM networks, the dynamic algorithm to further reduce energy consumption, reduce blocking rate and realize complete failure protection is the main problem faced in improving the reliability of green energy-saving networks. The energy-saving and survivability in the above-mentioned prior art Mechanisms cannot accommodate these issues
