Abstract

Software Defined Network SDN is a technique that centralized the control plane in one device and the data plane (forward plane) in the other devices connected and communicated via SDN protocols, so these devices will get instructions from a central entity called a controller to manage the network efficiently. The controller generally has a global view of the network topologies and can broadcast any management policy to all devices in the network easily. SDN makes the recent network more responsive and flexibly managed by delivering interoperable and programmable network services to network organizations all around the world. In this work, two real critical scenarios were investigated against other scenarios to manifest the SDN ability to deal with them. Finally, results show that the opted implementation features are better than the others in term of testing parameters.

Highlights

It is all agreed traditional networks are too expensive to deploy and manage, too complicated to control, and too hard to change or update.[1]
Software-Defined Networking (SDN) overcomes the complexity caused by different network protocols and configuration interfaces that different vendors use for their devices
An experimental test has been made on the ODL controller with topology shown in figure (1) with different case scenarios to show the SDN controller capabilities to deal with such scenarios

Summary

Introduction

It is all agreed traditional networks are too expensive to deploy and manage, too complicated to control, and too hard to change or update.[1]. A multi-vendor network requires network expertise to deal with network inconsistency, extensive knowledge is required to achieve heterogeneous devices that complicate the network segmentation. On another hand, the timeconsuming and error-prone will occur when deploying stage takes place by the network administrator which will be a highly administrative hassle to configure network standards. SDN overcomes the complexity caused by different network protocols and configuration interfaces that different vendors use for their devices. SDN gives a higher security level in managing network infrastructures and data centres with the ideal level of scalability for future network expansion. [5]
