Glossary
point-to-point Transmission of
data between two nodes where one
node is the sender and the other node
is the receiver.
Presentation layer Layer 6 in the
OSI model; details protocols
governing data formats and
conversions.
propagation delay The time it
takes for a signal to travel across the
network.
protocol A set of rules and
conventions that govern the
exchange of information between
communicating parties on a
network.
R
reconfiguration The operation by
which a station determines the
location of a fault and isolates it by
utilizing the redundancy of the dual
FDDI ring.
repeat frame The operation of
repeating a group of symbols on the
network in exactly the same manner
they were received by the station.
repeater A level 1 hardware device
that performs the basic actions of
restoring signal amplitude,
waveform, and timing of signals,
before transmission onto another
network segment.
ring Connections between two or
more stations that form a circular
topology.
RMT (Ring Management) That
portion of the Station Management
(SMT) function within an FDDI
station that receives status
information from the Media Access
Control (MAC) and the Connection
Management (CMT). The RMT then
reports this status to the SMT and
higher-level processes.
router A level 3 hardware device
that uses layer 3 protocols to control
network communication between
stations and forwards messages to
endstations or other routers.
