MCR
Minimum Cell Rate: A parameter determined by the ATM Forum for
traffic management of the ATM networks. MCR is specifically defined for
ABR transmissions and specifies the minimum value for the allowed cell rate
(ACR). See also: ACR and PCR.
MCTD
Maximum Cell Transfer Delay: In an ATM network, the total of
the maximum cell delay variation and the fixed delay across the link or node.
MCTD is one of four link metrics that are exchanged using PNNI topology
state packets to verify the available resources of an ATM network. There is
one MCTD value assigned to each traffic class. See also: MCDV.
MIB
Management Information Base: Used with SNMP management soft-
ware to gather information from remote devices. The management station
can poll the remote device for information, or the MIB running on the
remote station can be programmed to send information on a regular basis.
MIP
Multichannel Interface Processor: The resident interface processor on
Cisco 7000 series routers, providing up to two channelized T1 or E1 con-
nections by serial cables connected to a CSU. The two controllers are capable
of providing 24 T1 or 30 E1 channel groups, with each group being intro-
duced to the system as a serial interface that can be configured individually.
mips
millions of instructions per second: A measure of processor speed.
MLP
Multilink PPP: A technique used to split, recombine, and sequence
datagrams across numerous logical data links.
MLS
Multi-Layer Switching: Switching normally takes place at layer 2. When
layer 3 information is allowed to be cached, layer 2 devices have the capability
of rewriting and forwarding frames based on the layer 3 information.
MLSP
Multilayer Switching Protocol: A protocol that runs on the router
and allows it to communicate to the MLS-SE regarding topology or security
changes.
MLS-RP
Multilayer Switching Route Processor: An MLS-capable
router or an RSM (Route Switch Module) installed in the switch. See also:
RSM, MLS.
