A SDN Network Based on VLANs for Data Centers
Fei Xu, Yanwei Xu · 2016
The demands for the scalable and efficient network at data centers are becoming more and more intense recently.However, there are three problems needed to be solved, i.e., the ever-increasing number of actual or virtual machines demands, effectively managing these different machines and maintaining the effectiveness.This paper proposes a new software defined network (SDN) based on VLANs and its significant characteristic is to build a scalable layer 2/3 network for data centers based on the physical OpenFlow switches.Our framework has high performances because: 1) The operation of encapsulating and unpacking packets is not necessary; 2) Routing paths can be precomputed.
