A Study and Designing of Custom Network Configuration using Integrated Protocols in SDN Architecture IJTSRD
Today’s world emphasizes a lot on speed, performance and ease of use. Taking these demands into consideration it has become mandatory to change all existing systems and transform them into ones that can deliver these characteristics. One such system has been network architecture. Since many years’ vendors have been creating and developing their own Network Infrastructure, with different policies and different instruction sets. But communication between networks has taken up importance so as to reduce the timing taken by the data packet to pass through the security settings of another network and vice versa. Hence here is where Interoperability comes into play. If we can take all the networks and have a common controller for all the networks, it would reduce the time and complexity for communicating between them. A simple way to achieve it is through Software Defined Networking, where we can use the software to control the flow of data packets as well as monitor the network. Software Defined Networking is a networking prototype which allows network operators to manage networking elements using software running on an external server. This is accomplished by a split in the architecture between the forwarding element and the control element. The traditional network tends to be rigid. Once the forwarding policy has been defined, the only way to change it is by changing the configuration of all the affected devices.This is time consuming and puts a limit on scalability and meeting challenges of mobility and big data. In this context software defined networking (SDN) is being looked upon as a promising paradigm that has the power to change the way networking is done. By centralizing control, and making forwarding nodes simple, SDN offers flexible control over the traffic flows and the policies networks use to manage these flows. Along with the excitement, there have been apprehensions regarding SDN. In any organization, actual network is not confined to simple configuration. The real network configurations in these organizations are complex and represent more like bulky connectivity. The designing of custom network is done on the GNS3 platform. It is python based and the configurations on GNS3 can be moved to real world networks with minimal changes. The custom network refers to the configuration of network according to ones need and requirement. That means that number of router, switches and links are not defined, they may change as per the need. The various components of the SDN network is then studied in both the traditional and custom network. The adoption of SDN has still not done in physical network. There have been a number of trial deployments but very few production networks. In this paper, we would discuss the important implementation issues in SDN, the requirements it would fulfill in two fast growing areas wireless networks and clouds and the research that is taking place in these areas. We discuss, in some detail, the enrichments required in the SDN framework as far as security is concerned. Finally, we explore the future directions that SDN research is expected to take. The biggest benefit of Open Flow is to decouple the control plane from the data plane, allowing the centralized forwarding decisions in comparison to traditional distributed control network. As a result, we propose a Software-Defined coding network and address key technical challenges in practice.
