Abstract:

To solve the traffic scheduling optimization problem in the data center networks, an energy efficient routing algorithm (EERA) is proposed based on bandwidth matching in the software defined data center networks, and takes the advantage of the software defined network centralized control using classic Fat-Tree topology. EERA sorts the traffic according to their deadlines and traffic sizes and updates the link weights in the topology for each sorted traffic according to the amount of data. Then EERA deletes the links whose available bandwidth does not meet the amount of transmitting data and gets a new topology. In the redefined topology, EERA calculates all the available links between the source node and the target node, then selectes the optimal links from these available links that match the bandwidth required by traffic transmitting. Simulation results show that EERA reserves enough bandwidth for incoming traffic with no additional storage overhead, and reduces the network congestion. At the same time, EERA saves the network energy consumption and achieves the network load balancing.

Key words: data center network, software defined network, traffic scheduling, load balancing, energy efficient routing
