With the rapid development of information technology,the scale of the Internet is increasing.At the same time,the energy consumption of the network is rising.In order to reduce network energy consumption,the industry generally adopts the method of closing the link with low link utilization.However,the current network energy-saving scheme can not effectively ba-lance the trade-off among energy-saving rate,computational overhead and path stretch.In order to solve the above problems,this paper proposes a green energy-saving routing framework based on link correlation model.The framework supports different link correlation models.It only needs the network topology,not the real-time traffic matrix in the network,so it is easier to deploy in the actual network.Based on the green energy-saving routing framework based on link correlation model,this paper implements four different energy-saving green routing algorithms:LRC(link row correlation),LCC(link column correlation),LRCC(link row column correlation)and LBC(link betweenness correlation).Experimental results show that in the real topology published by The Internet Topology Zoo and the topology generated by Brite simulation,the average energy saving rate of LRC,LCC,LRCC and LBC is 12.65％and 7.17％higher than that of DLF algorithm,and their average path stretch under the real topology and simulated topology is 3.00％and 13.75％lower than that of DLF algorithm.
