Abstract
Abstract —This paper presents a complete guideline for developing OpenFlow infrastructure. OpenFlow is standard network protocol to manage traffic between routers and Ethernet Switches. This approach will help to create the next generation virtual network, which provides the solution for network management, flow control of packets, delay optimization etc without interfering the backbone network. Here a brief idea about all the supporting tools involved in the journey of OpenFlow has been introduced. This paper provides a solution with top to bottom approach to install OpenFlow network tools. On the basis of one by one approach user is able to solve the problem appeared during the installation with proper justifications. Index Terms —OpenFlow, Python, Mininet, NOX, Flowvisor. I. I NTRODUCTION Now a day the Network should fulfil the growing demand and handle the ever growing traffic as well. To come up with new technologies for networks [14][15], we need a testbed where we can implement the experiments or changes and can check the results. To create this testbed we use Software Defined Networking (SDN). It is an approach for network virtualization where the control plane is separated from the data plane and moved to an external software controller and OpenFlow [1][2][3] is the most used SDN solution. Open source is the best platform for designing and implementing a network. Here the open source software used is Ubuntu. First we need to create a network virtually using OpenFlow [4][5] and for this Mininet [8] is used. The source code for Mininet is written in python/C++. Controllers are used in OpenFlow network to manage the flow control. NOX [10][11] is most widely used controller since it is written in C++/python. Flowvisor [13] is a special purpose OpenFlow controller which acts as transparent proxy between control and data plane. The rest of the paper is organized as follows: Section II describes the introduction to Ubuntu and its installation. Section III discusses the application of python in OpenFlow technology. In Section IV a detailed explanation of emulator ―Mininet‖ used in Wired OpenFlow network and its installation is outlined. Section V & VI describe the brief introduction to NOX Controller and Flowvisor, and its installation is outlined. It also gives the solution of problem appeared during installation with proper justifications. Finally Section VII concludes the whole paper. Flow Chart of complete paper: OpenFlow based network Study of Flowvisor and installation of its supporting jdk6 and then installation of II. U
