The bigger promise of Software Defined Networking otherwise known as SDN is that it would be centralizing and simplifying control of enterprise network management. But what would be the specific advantages of Software Defined Networking? Different vendors would be creating different claims, but the most commonly cited benefits of Software Defined Networking are considered to be traffic programmability, greater agility, the ability to create policy-driven network supervision, as well as implementing network automation. The promise of SDN is considered to be the ability to allow networks to keep pace with the speed of change. So, before we discuss the benefits of the Software Defined Networking, it is recommended for you to gain detailed knowledge about it. I would suggest you join the courses which are offered by the SPOTO Club. One of the primary advantages of Software Defined Networking would be that it is going to create a framework to support more data-intensive applications such as big data and virtualization.
Benefits of Software Defined Networking:
- Centralized network provisioning.
Software defined networks provide a centralized view of the entire network, which would make it easier to centralize enterprise management as well as provisioning. For instance, more VLANs are becoming part of physical LANs, which would be creating a Gordian knot of links and dependencies.
- Holistic enterprise management.
Enterprise networks have to set up new applications as well as virtual machines on insisted to contain new processing requests like those for big data. SDN would be allowing the IT managers to experiment with network configuration without creating impact on the network. SDN would be also supporting the management of both virtual and physical switches and network devices from a central controller; something you couldn’t do with SNMP. SDN would be providing a single set of APIs to create a single management console for virtual and physical devices.
- More granular security.
One of the advantages of security defined networking would be that it appeals most to IT managers is centralized security. Virtualization has made network management very challenging. With virtual machines coming and going as part of physical systems, it would be quite difficult to consistently apply firewall and content filtering policies. When you would be adding in complexities like securing BYOD devices, the security problem would be compounded.
- Lower operating costs.
Administrative efficiency, better control of virtualization, improvements in server utilization, and other benefits should result in operational savings. Although it would be still early for showing real proof of savings, SDN should lower overall operating costs which eventually result in administrative savings since many of the routine network administration issues could be automated and centralized.
- Hardware savings as well as reduced capital expenditures.
Adopting SDN would also be giving new life to existing network devices. SDN would be making it quite easier to optimize commoditized hardware. Hardware which would be existing could be re-functioned using instructions from the SDN controller as well as less expensive hardware could be deployed to greater effect since new devices essentially become white box switches with all the cleverness which would be centered at the SDN controller.
- Cloud abstraction.
Cloud computing is here to stay as well as it would be evolving into a unified infrastructure. By abstracting cloud resources utilizing Software Defined Networking, it would be quite easier to unify cloud resources. The networking components that would be making up massive data center platforms could all be managed from the SDN controller.
- Guaranteed content delivery.
The ability to control and shape data traffic is considered to be one of the primary advantages of Software Defined Networking. Being able to automate and direct data traffic which would make it quite easier to implement quality of services (QoS) for voice over IP as well as multimedia transmissions. Streaming high-quality video would be quite easier because SDN is going to improves network responsiveness to ensure flawless user experience.
