multicast A packet sent to a specific group of endstations on a network.
multicast filtering A system that allows a network device to only forward multicast traffic
to an endstation if it has registered that it would like to receive that
traffic.
NIC Network Interface Card. A circuit board installed in an endstation that
allows it to be connected to a network.
OSPF Open Shortest Path First. A hierarchical Interior Gateway Protocol (IGP)
routing algorithm.
POST Power On Self Test. An internal test that a Switch carries out when it is
powered-up.
protocol A set of rules for communication between devices on a network. The
rules dictate format, timing, sequencing and error control.
QoS Quality of Service. A network prioritization scheme that monitors traffic
passing through the network and weights each packet according to the
type of data it carries and its progress though the network.
RADIUS Remote Authentication Dial-In User Service. An industry standard
protocol for carrying authentication, authorization and configuration
information between a network device and a shared authentication
server.
Rapid Spanning Tree
Protocol
An enhanced version of the Spanning Tree Protocol that allows faster
determination of Spanning Tree topology throughout the bridged
network.
Rate Limiting The restriction of traffic on a network connection to below its
maximum capacity. Typically rate limiting is used with
traffic
prioritization to ensure that the most important traffic is passed over
the link.
repeater A simple device that regenerates LAN traffic so that the transmission
distance of that signal can be extended. Repeaters are used to connect
two LANs of the same network type.
resilient link A pair of ports that can be configured so that one takes over data
transmission should the other fail. See also
main port and standby port .
