Network Redundancy

Redundancy

characteristic of devices that allows it to prevent against or recover from an instance of system failure

Example of Redundancy

By avoiding a single point of failure in a network’s configuration, you are ensuring that a network is redundant

What are three examples of redundancy?

Setting up star and mesh topologies for network devices, implementing load balancers, and configuring bastion servers

topologies

logical and physical design of a network

Star topology

Switch in the middle that directs traffic to devices through Mac addresses

Con of star topology

Reliance on a single device leads to a single point of failure that can disrupt entire system

Mesh topology

Three access points support the same network

Load balancing

When servers are overwhelmed with requests, they crash. Multiple redundant servers are used to complete the same tasks

Bastion Server

Server that is strengthened through strict security software and rules that protect the edge of your network
