What is the relationship between redundancy and resiliency in network design?

The relationship between redundancy and resiliency in network design is fundamentally about how redundancy contributes to the overall ability of a network to recover from failures and maintain service availability, which is referred to as resiliency.

When a network incorporates redundancy, it includes additional components or pathways that can take over if the primary components or pathways fail. This additional capacity allows the network to continue functioning even when there are equipment failures or issues with connectivity. Consequently, redundancy provides a safety net that enhances the system's ability to withstand and recover from unexpected events, thereby increasing its resiliency.

In summary, redundancy is a key element that directly supports and enables the resiliency of a network by ensuring that alternate resources are available to mitigate the impact of potential failures. Thus, redundancy is not just a complementary feature; it is an essential building block for creating a robust and resilient network environment.
