The Future of Networking with SDN

By CIOReview | Wednesday, August 9, 2017

With the increased number of computer and mobile devices being used in organizations, CIOs are in need of a dynamic, manageable, as well as cost-effective solution that can effectively handle today’s high-bandwidth applications. Making a revolution in the networking landscape, Software-defined networking (SDN) is one of the most innovative technologies designed for network control and automation. Adding up the advantages of SDN, unlike today’s device centric technology, SDN is a Human Centric Technology that allows administrators to effortlessly adopt faster and efficient.

SDN technology is a unique approach to computer networking in which a network administrator can leverage a set of software tools to programmatically initialize, control, change and manage network behavior dynamically utilizing the open interfaces in the network. With an SDN application, network administrators can improve and change the methods in which network devices such as Routers, Switches and other components handle data packets. The application provides complete control of the network policies and rules with a centralized control panel. Moreover, with various diagnostic capabilities, the system allows administrators to seamlessly recognize network errors. SDN allows the administrators to seamlessly configure, manage, secure, and optimize the resources within a network rapidly. They can configure the program themselves as these applications are independent to any particular guidelines or architectures.

The software defined networking architecture decouples the complete network control as well as the forwarding functions within a particular network. The solution enables network controls to be directly programmable. In addition, it allows all the underlying infrastructures within a network to be abstracted for applications and network services.

Seamless Provisioning- SDN allows administrators to manage services almost in real-time. New deployments and updates can be performed faster without any hardware installations.

Reduced Expenses: With SDN, organizations investment is comparatively less in hardware and need less space in the server room.

Improved security: SDN boosts security because it’s easier for us to deploy updates when an attack takes place. It’s also possible to isolate and contain problems faster and better. Attacks suck as Distributed Denial of Service can be effectively tackled by increasing the points.

Centralized Management: With the complete network intelligent completely centralized in the software-based SDN controllers, a global view of the network architecture will be available in the console. Administrators can utilize SDN as a single switch for complete control over the network. Moreover, the system is directly programmable with decoupling functions in it.

Agile: With the SDN abstracted control of the network devices, administrators can dynamically adjust the network wide traffic flow to meet the changing network requirements within an organization.

Open standards-based and vendor-neutral: As SDN applications are implemented with open standards; these applications can seamlessly simplify the network design and operates based on the instructions from the SDN controller. Moreover, the device is independent on multiple, vendor-specific device and protocols.

Open Network Foundation

In a venture to promote the adoption as well as implementation of SDN across organizations, Open Network Foundation is a user-driven organization. The organization promotes implementation of SDN through open standards where such standards are important for the networking industry to move ahead. As part of their initiative the organization is developing various open standards as well as vendor-neutral standard communications interface defined between the control and forwarding layers of an SDN architecture.

Today, Software Defined Networking has a bright future ahead as various organizations across the globe have already started harnessing its potential. However, as every coin has a flip side, console and remote capabilities and security policies with SDN has to be improved to overcome the modern cyber challenges.
