What is meant by 'redundancy' in network design?

Redundancy in network design refers to the practice of including additional components that serve as backups to increase the reliability and availability of the network. When a primary component fails—such as a server, router, or communication link—these redundant components take over to ensure that the network continues to function without interruption. This design principle is vital in mission-critical environments where uptime is crucial, as it minimizes the risk of service disruptions. Incorporating redundancy enhances fault tolerance and helps maintain continuous service, providing a safeguard against hardware failures, network outages, or other unforeseen issues. This ensures that data is reliably transmitted and services remain operational even in the face of individual component failures.
