SDN in the New Business Frontier

Businesses capitalizing on SDN are likely lured in by its potential to support data-heavy applications.

FREMONT, CA: Enterprise infrastructure layer comprises several networking types of equipment that form an underlying network to forward network traffic. It could be a set of network switches and routers in the data centre. This layer is a physical one over which network virtualization would be laid down through the control layer. Software-defined networking separates the network control plane and the forwarding plane, aiming to simplify and enhance network control. IT teams are more able to quickly adapt to changing business needs and application requirements. But beyond that purpose, there are innumerable advantages that make SDN a worthy venture. Here is more to know.

SDN is a highly flexible, agile method to adapt to increasing networking requirements and allow automation and agility. SDN makes network control a programmable entity by separating the network control and planes and abstracts the infrastructure underneath. Network engineers advantage from SDN because they no longer have to wrangle individual network devices to provide network services, connect locations and applications, or govern resource and potential utilization. Instead, SDN takes care of this activity, directing these individual switches to offer services when the business needs them.

In a conventional network environment, networks are unaware of the requirements for applications running throughout the system. Operators can observe application features like packet size, volume, latency and errors, but largely the types of applications and information about health or required performance can not always be decided; in a software-defined network, the applications can have data about the network, and networks configurations can be tailored to the applications, generating a two-way street of information.

There are three major factors that make up software-defined networking. First, firms have SDN applications. These applications relay actions and request resources through the SDN controller using APIs. SDN applications can assume several forms and serve various functions, like network management, offering analytics, adding security or common network functions. IP address management (IPAM), managing quality of service (QoS), load balancing, or identification and mitigation of a denial of service (DoS) cyber attack are some example.
