Virtual Network Embedding Resource Trading and Expanding Problem of Time-Varying Traffic Problem in EONs

Abstract

In this article, the virtual network embedding resource trading and expanding (VNE-RTE) problem on elastic optical networks (EONs) with time-varying traffic was studied. Several trading and expanding methods were proposed to solve the VNE-RTE problem. We show the effectiveness of the proposed methods through extensive simulations. Simulation results show that the proposed RTE scheme can improve the overall computing/spectrum resource utilization of an EON.
