MID
Message Identifier: The message identifer is used to associate ATM cells that carry
segments from the same higher layer packet.
MIR
Maximum Information Rate: Refer to PCR.
Mrm
An ABR service parameter that controls allocation of bandwidth between forward
RM-cells, backward RM-cells, and data cells.
MMF
Multimode Fiberoptic Cable: Fiberoptic cable in which the signal or light
propagates in multiple modes or paths. Since these paths may have varying lengths,
a transmitted pulse of light may be received at different times and smeared to the
point that pulses may interfere with surrounding pulses. This may caus e the sign al
to be difficult or impossible to receive. This pulse dispersion sometimes li mits t he
distance over which a MMF link can operate.
MPEG
Motion Picture Experts Group: An ISO Standards group dealing with video and
audio compression techniques and mechanisms for multiplexing and synchro nizing
various media streams.
MPOA
Multiprotocol over ATM: An effort taking place in the ATM Forum to standardize
protocols for the purpose of running multiple network layer protocols over ATM.
MPOA Client
A device which implements the client side of one or more of the MPOA protocols,
(i.e., is a SCP client and/or an RDP client. An MPOA Client is either an Edge
Device Functional Group (EDFG) or a Host Behavior Functional Group (HBFG).
MPOA Server
An MPOA Server is any one of an ICFG or RSFG.
MPOA Service Area
The collection of server functions and their clients. A collection of physical devices
consisting of an MPOA server plus the set of clients served by that server.
