【Abstract】 A new energy-aware routing mechanism based on fruit fly optimization algorithm(FOA)was proposed for general topologies(ERGT)to improve the efficiency of data center network in this paper.At first,a model calculating the switching equipment′s power in data center networks was deduced.Then,the routing energy-aware routing mechanism based on FOA was designed.This mechanism,presents a formulation for flow assignment simulating the strategy of fruit flies flying to adjust and optimize the direction and the position when they are looking for food,proposes the heuristics to determine next hot constantly,finds the best energy saving routing.At last,we validate the mechanisms proposed in this paper are feasible and effective.Simulation results reveal that the routing mechanisms designed are superior to existing algorithm.更多还原
