A fully network architecture design will ensure that web services will remain available even if one network’s service is unavailable and interrupted. It serves the epitome medium for network fail over. Fully redundant network can be defined as the process through which additional instances of network devices and communication channels are installed within the network infrastructure.
Network redundancy is mainly implemented in big enterprises networking infrastructure to ensure a redundant source of network communications. It acts like a backup mechanism for quickly swapping network operations onto redundant infrastructure in case of network failure. Typically, redundancy is achieved by combining alternate network paths, which are then implemented through redundancy standby routers and switches. When the primary route of the network is unavailable due to network interruption, the alternate path can be quickly deployed to reduce the downtime and progress the network services.
There are so many kinds of redundant device available, and among them the most popular form of network redundancy device is backup storage device. Another type is a secondary power supply. High traffic web servers and other computing instances may have multiple power supplies that take over in case of primary supply fails. From local area networks to internet backbone mesh, it is common to have redundancy path to ensure the continuity of network services.
