Glossary
the bandwidth, the more information
can be sent through a circuit during a
given amount of time.
baud Measurement of signaling
speed indicating line changes per
second, where line changes can
represent one or more bits. The baud
is equal to bits-per-second only for
line changes representing a single
bit.
beacon A special frame used by
media access control to announce to
the other stations that the ring is
broken. The resulting action
attempts to restructure the network
to account for the probable fault.
bridge An internetworking device
used to connect two or more
computer networks and to forward
packets among the networks.
Bridges operate at the Link layer of
the OSI model.
Bus Latency Elapsed time from
bus master request until bus master
is given control of the bus.
bypass The ability of a station to be
optically or electronically isolated
from the network while maintaining
the integrity of the ring.
C
CFM (Configuration
Management) That portion of the
Connection Management (CMT)
within the Station Management
(SMT) function of an FDDI station
that provides for the configuration of
PHY and MAC entities within a
node.
claim process A technique used to
determine which station will
initialize the FDDI ring.
CMT (Connection
Management)
That portion of
the Station Management (SMT)
function within an FDDI station
that controls the insertion,
removal, and connection of the
PHY and MAC entities within that
station.
concentrator An FDDI node that
provides attachment points (through
M ports) for stations that are not
connected directly to the dual ring.
The concentrator is the focal point of
the dual ring of trees topology.
counter-rotating ring An
arrangement where two signal
paths, whose directions are
opposite, exist in a ring topology.
