OSPF
Open Shortest Path First. A routing protocol that maintains a map of all other
routers and the networks to which they connect. Sends short messages asking
whether a neighbor is alive and reachable. More efficient, scalable than
vector-distance routing protocols that maintain table of all known destinations
and number of hops to reach them.
PCI
Peripherals component interface; a standard developed by Intel Corporation that
defines a local bus system; most modern PCs include a PCI bus in addition to a
more general ISA expansion bus
Port Density
Number of ports, either physical or logical, per network device
Port Mirroring
Advanced feature of switching hubs that allows one port's MAC layer data to be
replicated to another port for monitoring by a network analyzer
QoS
Quality of Service. Network device capabilities that provide some guarantee of
performance such as traffic delivery priority, speed, latency, or latency variation.
Delivery of good-quality audio or video streams typically requires QoS
capabilities.
QoSR
Quality of Service Routing. Procedures being studied by the IETF (RFC2386) to
select routing paths based on network resource availability and the quality
requirements of the traffic flow. Current routing protocols (such as RIP, OSPF,
and BGP4) do not consider the link capacity when making route assignments.
RMON
Remote Monitoring; a network management protocol that allows network
information to be gathered at a single workstation
Route
A communication path between two devices on different networks
Routing
The process of delivering a message across a network or networks
Router
A network device that forwards packets to destinations that a hub or Layer 2
switch cannot reach. A router implements various protocols to maintain
information on the location of other routers. A router reads the Layer 3 network
address information in every packet that it receives and determines whether it
should be dropped or forwarded. If it is to be forwarded, the router looks in its
routing table to find the best route between a sender and receiver.
Routing Tables
A table that a router maintains of all known routes on an internet
