Virtual Network Embedding in Elastic Optical Data Center Network

Abstract

The booming internet services urge the research on the cloud computing and the network resource utilization.The combination of elastic optical network and data center can solve the network resources deficient problem and the computing resources unbalanced problem.Virtual optical network embedding provides the way of resource high-efficiency.In this paper, we propose a novel virtual networks embedding algorithm orienting spectrum resource, and the simulation results verify its superiority on increasing spectrum resource utilization and reducing demand blocking rate.
