Abstract:

As virtual networks services emerge increasingly with higher requirement of reliability and survivalbility, great challenges and demands are presented to the Elastic Optical Networks (EON). Aimed to solve this problem, this paper proposes a risk awareness based virtual network mapping stragegy of elastic optical network. In this article, a risk awareness model of virtual optical network is established, which includs node risk degree, link risk degree and other factors together. Moreover, the risk awareness model based virtual network mapping strategy is proposed with detailed procedures. Test results show that the proposed approach is able to improved services security supporting ability of EON.

I. Introduction

With rapid development of software defined network (SDN) technologies, optical networks have achieved great progress toward the programmable ability [1]. Benefiting from great progress of optical communications, the elastic optical network (EON) makes full use of Orthogonal Frequency Division Multiplexing (OFDM) in the optical field. By introducing new types of optical devices with variable bandwidth ability, the EON can provide great support to virtual network services [2]. As one kinds of newly emerged technologies, the network virtual technology allows various logically isolated networks to share the same optical layer network and physical resources.
