A SDN Based Scalable Network Across Data Centers
Yanwei Xu, Xiaoyuan Lü · 2016
The demands for the network across data centers are becoming more and more intense recently.However, there are three problems need to be solved, i.e., the ever-increasing number of actual or virtual machines demands, effectively manage these different machines and maintain the effectiveness.A scalable network across data centers is a very important technology to solve them.This paper proposes a new software defined network (SDN) based scalable network framework and its significant characteristic is to build a scalable layer 2/3 network that across data centers over the internet by using SDN's technologies.Our framework has high performances because: 1) The operation of encapsulating and unpacking packets is not necessary; 2) Routing paths can be pre-computed; 3) Traffic engineering to be implemented.
