10 Must-Watch Futuristic IT Trends


#2 Software Defined Networks:

Software Defined Networks (SDN) abstracts the system so that it can transform the network topology from box/port at a time configuration to flow at a time, linked to application. Companies use SDN to get an overall topology of the networks within the system, both internal and external. A SDN controller mainly comprises of switches, firewalls and ADCs. These components provide the abstracted view to provisioning and managing the network connections and services that the applications and the operator require.

One best example is OpenFlow protocol. This protocol helps operators create their own APIs, control and management schemes, so that the application requirements of the operator are met. Apart from these, some SDN protocols are primarily designed upon an application level logic, rather than from the traditional network paradigm of protocol, device and link-based thinking.
