Analysis and Performance Evaluation of Different Methods to Achieve Way-Point Enforcement in Hybrid SDN

Abstract

Software Defined Networking (SDN) is a new paradigm that gives central control over distributed SDN-enabled switches. SDN is begin adapted very rapidly to gain the advantages of centralized programmable control over the network. But it is difficult to go for a green-field deployment of SDN due to several reasons. It requires a huge budget to install SDN network infrastructure. The deployment of SDN devices will take some time, due to which the network can go down. The safe option is to go for partial deployment, where the SDN devices can be installed incrementally in the traditional network. Over the last few years, the research community brings their attention to hybrid SDN networks. To gain SDN control over the network traffic, it has to go through at least one SDN switch. There exist a few solutions which enforce the traffic to go through the SDN switch. In this paper, our aim is to analyze and evaluate the performance of existing methods to achieve way-point enforcement in hybrid SDN networks in terms of average path length, and percentage of way-point enforcement achieved.
