What is the purpose of network redundancy?

The purpose of network redundancy is fundamentally to ensure network availability in case of failures. Redundant systems or components are put in place to maintain continual operation and minimize downtime. By having alternative pathways or duplicate systems, a network can quickly recover from hardware failures, software malfunctions, or other disruptions without significantly impacting users or services.

For instance, in a typical network setup, if one server or connection fails, a redundant server or alternative connection can take over, allowing users to continue accessing resources seamlessly. This capability is crucial for businesses that rely on constant connectivity and data access to operate effectively.

Enhancing network speed, reducing costs, or limiting network size, while potentially relevant in certain contexts, do not directly relate to the primary goal of redundancy, which is maintaining service continuity and reliability in the face of unexpected events.
