Virtual Router Redundancy Protocol (VRRP)
A protocol that uses a virtual IP address to support a primary router and multiple
backup routers. The backups can be configured to take over the workload if the
master fails or to load share the traffic. The primary goal of VRRP is to allow a
host device which has been configured with a fixed gateway to maintain network
connectivity in case the primary gateway goes down.
XModem
A protocol used to transfer files between devices. Data is grouped in 128-byte
blocks and error-corrected.
