Network Resilience
Network Resilience is a subjective element of network design and implementation, and is the idea that certain applications, users or branches are more important than others; and that they deserve additional spending to ensure that they are made available a higher percentage of the time.
In real terms, this may involve installing a backup circuit into a branch on a Wide Area Network in case the main circuit fails. If this connectivity is deemed very important, it is possible to diversely route backup circuits to guard against PoP or Local Exchange failure.
Other examples include UPS’s, Generators, dual power supplies, dual interfaces, dual modules, mirrored servers, data backup etc. Today’s increasing reliance on electronic data and networks has prompted many organisations to have dedicated DR (Disaster Recovery) strategies in place.
