Is Sdn The Next Big Thing Or All Hype In It Industry}

Submitted by: Subodh Sharma

Software Defined Networking (SDN) is complementary approach that enables new ways to build, operate and design networks. It helps the organizations to accelerate applications deployment, reduce IT cost, and accelerate delivery through workflow automation. Over the past decades, tons of new devices have been innovated to access the application and networks. Even our data are stored on cloud platforms. Networks are stretching or expanding its limit to meet the demand of increasing people without changing the network architecture. It enhances the concept of virtualization, network flexibility, and resources utilization. It provides mobility at scale by delivering automated, application delivery through cloud architecture. Optrum Technologies a new SDN testing startup provides similar automated services that can boost your network infrastructure at any scale.

Big Switch Networks a network virtualization unveiled Switch Light that focused on the adoption of protocol like Open Flow communications and SDN Test Networking. The advantage of using Switch Light Software is that it can be deployed as both silicon based physical switching or Switch for server hypervisors. Open Flow is the best known protocol of SDN which acts as the southbound interface. In other word, Open Flow protocol separates control plane and data plane.

What SDN can do?

SDN Services can extend the size of network for flexibility, decreased latency (fast communication), QoS (Quality of Service) and Dynamic traffic flow. A data center with large network cannot support dynamic requirements like server virtualization etc. But using SDN technology, we can change WANs, branch networks and campus network. Software Defined Networking (SDN) accomplished these daily requirements by converging the application and network into a centralized platform. By doing this, they can configure the entire network infrastructure and automate the services. By deploying SDN technologies, we can achieve the following network benefits:

1). Ability to Use open API

2). Supports Network segmentation

3). Network Visibility

4). Reduced Operational Cost

5). Network Flexibility

6). Rapid provisioning of Network

Initially, when SDN came into existence, it was mainly focusing on separation of Control plane. This decides how packets will flow through the network from place to place i.e. data plane (carries data). SDN Technologies deploys an application that has controller to manage data plane. Applications uses North-Bound interface to talk with the controller.

Many hypervisor cloud providers like Apple, Google, and Microsoft have already implemented SDN automation testing techniques to manage their network. The network where SDN is deployed can detect traffic flow and select the best path based on application type, QoS (Quality of Service), etc. It provides APIs to the application for the end to end configuration.

SDN is becoming an integral part of todays network architectures in WANs, Campus and large data center. Among the IT decision makers, Software Defined Networking (SDN) Tools is the top most priority as per the survey conducted at the end of 2014. IT decision analyst considers SDN as the model for next generation network architecture. Along with Network virtualization, it suited the most critical business demand in networking domain. To fulfill the critical business demand, Optrum started its own SDN testing services and winning the IT market.

Conclusion:

At the end, we came to the conclusion that SDN Network Testing allows a complex network to be configured, programmed, and manipulated through software tools. It does not speak about the standard protocols like IS-IS, MPLS, BGP, IPv6 etc. It has been considered as the future of networking because it has the power to make the network infrastructure flexible with reduced operational cost. For any SDN testing related solutions, you can go with Optrums services as it is trusted across the world.
