Glossary 689
MBONE multicast backbone: The multicast backbone of the Internet, it is
a virtual multicast network made up of multicast LANs, including point-topoint
tunnels interconnecting them.
MCDV Maximum Cell Delay Variation: The maximum two-point CDV
objective across a link or node for the identified service category in an ATM
network. The MCDV is one of four link metrics that are exchanged using
PTSPs to verify the available resources of an ATM network. Only one
MCDV value is assigned to each traffic class.
MCLR Maximum Cell Loss Ratio: The maximum ratio of cells in an ATM
network that fail to transit a link or node compared with the total number
of cells that arrive at the link or node. MCDV is one of four link metrics that
are exchanged using PTSPs to verify the available resources of an ATM network.
The MCLR applies to cells in VBR and CBR traffic classes whose CLP
bit is set to zero. See also: CBR, CLP, and VBR.
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 software
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 connections
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 introduced
to the system as a serial interface that can be configured individually.
mips millions of instructions per second: A measure of processor speed.
