Glossary
Ping
Packet InterNet Grouper. PING is a program used to test whether a
particular network destination on the Internet is online (i.e. working) by
repeatedly bouncing a “signal” off a specified address and seeing how
long that signal takes to complete the round trip. No return signal - site is
down or unreachable. Portion is returned - trouble with the connection.
Protocol
Procedure or set of rules.
Point-to-Point
Protocol (PPP)
Provides a standard means of encapsulating data packets sent over a
single-channel WAN link. It is the standard WAN encapsulation
protocol for the interoperability of bridges and routers.
PVC
Permanent Virtual Circuit. A PVC is a permanent channel connection
between two ATM devices. PVC’s allow network transmissions to be
started without having to first establish a connection with the end point
ATM device. When a PVC is constructed, the end points of the
connection will agree upon a path in which data will travel, and therefore
agree upon the route that data will travel to reach its destination.
QoS
Quality of Service. QoS is a measure of the telecommunications (voice,
data or video) service quality provided to a subscriber.
RADIUS
Remote Authentication Dial-In Service. RADIUS is a client/server-
based authentication software system. The software supports remote
access applications, allowing an organization to maintain user profiles in
a centralized database residing on an authentication server which can be
shared by multiple remote access servers.
RIP
Routing Information Protocol. RIP is based on distance vector
algorithms that measure the shortest path between two points on a
network, based on the addresses of the originating and destination
devices. The shortest path is determined by the number of “hops”
between those points. Each router maintains a routing table, or routing
database, of known addresses and routes; each router periodically
broadcasts the contents of its table to neighboring routers in order that the
entire network can maintain a synchronized database.
