cost effective survivable virtual optical Network Mapping in flexible bandwidth optical Networks
Journal of Lightwave Technology, 2016Co-Authors: Bowen Chen, Weisheng Xie, Jason P. Jue, Yongli Zhao, Jie Zhang, Gangxiang ShenAbstract:This paper addresses the minimum Network cost problem for survivable virtual optical Network Mapping in flexible bandwidth optical Networks. For each virtual link, we provide dedicated-path protection, i.e., primary path and backup path, to guarantee high survivability on the physical Network. To simplify the virtual links Mapping, an extended auxiliary graph is constructed by coordinating the virtual optical Network and the physical Network. We develop an integer linear program (ILP) model, the LBSD (the largest bandwidth requirement (LB) of virtual links versus the shortest distance (SD)) Mapping approach, the LCSD (the largest computing (LC) resources requirement versus the shortest distance) Mapping approach to minimize the Network cost for a given set of VONs. For comparison, we also introduce one baseline Mapping approach, named LCLC (the largest computing resources requirement versus the largest computing resources (LC) provisioning), and the lower bound. Simulation results show that, comparing to the LCLC Mapping approach, the ILP model, the LBSD and LCSD Mapping approaches not only solve the problem of minimizing the total Network cost but also guarantee that the spectrum usage and the number of regenerators are minimum. The ILP model and the LBSD Mapping approach are greatly close to a lower bound of Network cost and perform the same results as a lower bound of spectrum usage in both the 6-node Network and the 14-node Network. As a result, our proposed LBSD Mapping approach can efficiently reduce the Network cost, spectrum usage, and the number of regenerators, which is near the optimal solutions of the ILP model.

Survivable impairment-constrained virtual optical Network Mapping in flexible-grid optical Networks
Journal of Optical Communications and Networking, 2014Co-Authors: Weisheng Xie, Jason P. Jue, Qiong Zhang, Xi Wang, Qingya She, Paparao Palacharla, Motoyoshi SekiyaAbstract:In this paper, we study the problem of survivable impairment-constrained virtual optical Network Mapping in flexible-grid optical Networks (SIC-VONM). The objective is to minimize the total cost of working and backup resources, including transponders, regenerators, and shared infrastructure, for a given set of virtual optical Networks, which can survive single link failures. We first provide the problem definition of SIC-VONM, and then formulate the problem as an integer linear program (ILP). We also develop a novel heuristic algorithm, together with a baseline algorithm and a lower bound for comparison. Numerical results show that our proposed heuristic achieves results that are very close to those of the ILP for small-scale problems and that our proposed heuristic can solve large-scale problems very well.
