Problems solved by technology

However, experience shows that the average link bandwidth occupancy rate of the backbone network is less than 40%
However, the link must remain on even when bandwidth utilization is low, which means a lot of power is wasted
[0004] The method of determining the route in the prior art has the problems of poor energy-saving effect and long calculation time of energy-saving route

Abstract

The embodiment of the invention provides a method of determining energy-saving routing, and relates to the communication field. The method comprises the steps of: obtaining a topological structure, a starting node, a destination node and traffic data of a network, wherein the traffic data comprises traffic records between all nodes in the network; calculating the energy-saving routing between the starting node and the destination node and the reserved bandwidth corresponding to the energy-saving routing by an integer linear programming algorithm according to the topological structure and the traffic data of the network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for determining an energy-saving route. Background technique [0002] The operation of the Internet consumes a large amount of electricity. In 2007, the electricity consumed by the Internet accounted for 5.3% of the global electricity consumption that year, while the total electricity consumed by the Internet in the United States accounted for 9.4% of its total electricity consumption in the same year. At the same time, a large amount of electric energy is wasted among the large amount of electric energy consumed. With the continuous expansion of the network scale and the rapid growth of business volume, the network's demand and consumption of electric energy continue to increase, which has exerted tremendous pressure on the network's operating costs and ecological environment. Therefore, network energy-saving technology has been paid more and more attention. [0...
