SDN Controller

The SDNSoftware-Defined Networking. SDN is an umbrella term encompassing several kinds of network technology aimed at making the network as agile and flexible as the virtualized server and storage infrastructure of the modern data center. Controller provides an improved networking infrastructure through the following enhancements:

Separation of control-plane and data-plane functions

Centralized manageability

Dynamic programmability of network devices

Traditional networks can experience high latency and inflexibility, as the number of new applications and features continues to grow. All control and forwarding functions take place on the same device, and features can only be provisioned statically through manual intervention. The SDNSoftware-Defined Networking. SDN is an umbrella term encompassing several kinds of network technology aimed at making the network as agile and flexible as the virtualized server and storage infrastructure of the modern data center. Controller provides a more efficient and simple way to build, deliver, and manage features throughout the network.
