3.4 Redundancy
In some network environments, users need to set up redundant loops in the network to provide a backup path for
disconnection or a network device breakdown. But if there are many network devices in the network, then each host
needs to spend more time and cross many network devices to associate with each other. And sometimes the
disconnection happens in a busy network, so the network must recover in a short time. Setting up redundancy on your
network helps protect critical links against failure, protects against network loops, and keeps network downtime at a
minimum. For example, if the Delta switch is used as a key communication component of a production line, several
minutes of downtime may cause a big loss in production and revenue.
3.4.1 Redundancy Ring
The Redundany Ring topology consists of nodes having two ports participating in Redundancy Ring.
It can reduce unexpected damage caused by network topology change. It supports three of ring topology: Ring, Coupling
Ring and Dual Homing.
