Abstract:

Network virtualization has recently emerged as a promising solution for diversifying the future Internet architecture into separate virtual networks (VNs). The problem of efficiently embedding multiple independent VNs over a common substrate infrastructure is a challenging problem on cloud computing platforms and large-scale future network testbeds. To solve this problem,we take advantage of aMap-Reduce framework, decomposing a VN request into meta-requests, using a link-priority algorithm and pheromone transmission based on multi intelligent route nodes, which have the ability to distribute meta-requests and collect meta-request embedding results in the substrate, and assignVNs to the substrate physical network in a distributed and parallelmanner.Adistributed and parallelVN embedding protocol is proposed to communicate and exchange messages among substrate nodes to achieve successful embedding. Results of implementation and a performance evaluation of the distributed and parallel VN embedding algorithm in terms of embedding time, acceptance ratio, produced messages and revenue and cost are presented at the end of this paper. © 2013 Trade Science Inc. - INDIA.
