Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes
that share the same collision domain
regardless of their physical location or
connection point in the network. A VLAN
serves as a logical workgroup with no physical
barriers, and allows users to share information
and resources as though located on the same
LAN.
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.
