Question

The network availability and faster provisioning in the era of the digital world is a high priority. How Software-Defined Network can play a role in providing a high availability network. Provide a solution to identify and self-heal in case of failure or impact in the network.

​

Answer 1

Answer:

Software-defined networking (SDN) is an architecture that aims to make networks agile and flexible. The goal of SDN is to improve network control by enabling enterprises and service providers to respond quickly to changing business requirements.

Explanation:

In a software-defined network, a network engineer or administrator can shape traffic from a centralized control console without having to touch individual switches in the network. The centralized SDN controller directs the switches to deliver network services wherever they're needed, regardless of the specific connections between a server and devices.

This process is a move away from traditional network architecture, in which individual network devices make traffic decisions based on their configured routing tables.
