Problems solved by technology

However, the MIP model routing is based on the multi-commodity flow model, which requires a centralized controller to specify service routes instead of routers determining routes based on link weights. This requires changes to the network environment, so it is not suitable for traditional IP networks. At the same time, the MIP model can only solve small-scale networks.

Abstract

The invention discloses an energy saving weight design method in an IP network, comprising steps of designing an energy saving weight through combining a link layer and a network layer so as to determine business distribution in the network to close part of idle line cards and links in order to achieve the goal of minimization energy consumption and optimization of energy saving, considering the real energy consumption constitution in the IP network and being applicable to the IP networks with any scale without modifying the network protocol. The energy saving weight design method in the IP network realizes the energy saving maximally while guaranteeing the connectivity and the service quality of the network.

Description

technical field [0001] The invention belongs to the technical field of network communication, and more specifically relates to a method for designing energy-saving weights in an IP network. Background technique [0002] In IP networks, due to potential economic benefits and expected environmental impacts, reducing unnecessary energy consumption has become a focus of network research, and these energy consumption issues are often called "green network" issues. In recent years, many green network technologies have emerged, which save energy consumption for the network at various levels. Among them, at the link layer, since the energy consumption of the link is almost independent of its load, it can save energy by closing the link; in the network At the layer level, energy-aware routing is to consider energy consumption when formulating routing strategies for the network. It mainly studies how to use the least network resources to provide routing and forwarding services in the ...
