Abstract

Lack of flexibility and scalability on traditional networks require more studies and researches in the area and this leads to the introduction of Software Defined Networking (SDN). The main objective of Software Defined Networking is to separate the control plane from the data plane and introduce the concept of Programmable Network. OpenFlow is a protocol used in Software Defined Networking architecture as a communication channel between the data plane and the control plane. Different applications can easily be integrated with the control plane in order to avoid vendor specificity issues with greater speed and greater scalability in terms of routing and forwarding. Completely shifting from traditional networks to this new architecture may not be an easy task and it is not also the target of Software Defined Networking, instead it encourages to shift step by step. The OpenFlow specification introduces two forms of implementations: pure and hybrid OpenFlow implementations. The hybrid implementation supports both traditional packets forwarding as well as OpenFlow network architecture. In this work, we present a performance analysis of the hybrid OpenFlow architecture in terms of throughput, end-to-end delay, and scalability on Local Area Network (LAN) side by side with the pure OpenFlow implementation. The aim is to explore how OpenFlow hybrid network can be implemented on the simulation environment and to see what enhancements it can bring to the OpenFlow network.
