Abstract

The traditional methods may cause network congestion and load imbalance when scheduling the elephant flows in data center networks. To deal with these issuses, this paper proposed scheme ACO-SDN, which was based on ACO(ant colony) algorithm in SDN data center networks. It built an ILP model according to the flow scheduling problem, with the object of minimize the maximum link utilization. Then, it employed ant colony algorithm to solve the ILP model through redefining its parameters and operations. It obtained the optimal route of rerouting elephant flows. The experimental results show that, in comparisons with ECMP(equal-cost multi-path routing) and GFF(global first fit) algorithms, ACO-SDN algorithm lowers down the maximum link utilization rate, and effectively improves the network bisection bandwidth of networks.
