Abstract
Internet architecture is under stress by current Internet applications. Internet applications are resource demanding in terms of bandwidth, device configurations, route selection, and troubleshooting. Current Internet does not meet the user need; therefore, the Internet architecture should to be redefined in order to meet the demand of the resource-hungry applications. In this paper, we have analyzed the need of Software Defined Networking (SDN) to restructure the current Internet architecture. In addition, an experimental study of web request and reply based on open flow protocol is conducted to demonstrate the working of open flow protocol between open flow switch and an open flow controller in an SDN topology created in mininet. The analysis of traffic shows the messages exchanged between the open flow entities and the parameters contained in these messages.
