PROJECT TITLE :
Incremental Deployment and Throughput Maximization Routing for a Hybrid SDN - 2017
ABSTRACT:
To explore the advantages of software outlined network (SDN), while preserving the legacy networking systems, a natural deployment strategy is to deploy a hybrid SDN incrementally to enhance the network performance. During this paper, we have a tendency to address two technical challenges: an incremental deployment strategy and a throughput-maximization routing, for deploying a hybrid network incrementally. For incremental deployment, we have a tendency to propose a heuristic algorithm for deploying a hybrid SDN below the budget constraint, and prove the approximate issue of one- one/e. For throughput-maximization routing, we have a tendency to apply a depth-initial-search technique and a randomized rounding mechanism to unravel the multi-commodity h-splittable flow routing drawback during a hybrid SDN, where h = one. We additionally prove that our technique has approximation ratio O(one/log N), where N is the quantity of links in a very hybrid SDN. We have a tendency to then show, by both analysis and simulations, that our algorithms will get significant performance gains and perform better than the theoretical worst-case certain. For example, our incremental deployment theme helps to reinforce the throughout about fortypercent compared with the previous deployment theme by deploying a small variety of SDN devices, and also the proposed routing algorithm can improve the throughput regarding 31p.c compared with ECMP in hybrid networks.
