message digest 5
MD5 is a security algorithm that takes an input message of arbitrary length
and produces as an output a 128-bit message digest of the input. MD5 is
intended for digital signature applications, for which a large file must be
securely compressed before being encrypted.
media dependent adapter
An MDA is a pluggable interface module that distributes traffic between the
network and the system IOM. It is also referred to as a daughter card.
management information base
A formal description of a set of network objects that can be managed using
SNMP.
multiprotocol label switching
MPLS is a technology in which forwarding decisions are based on
fixed-length labels inserted between the data link layer and network layer
headers to increase forwarding performance and flexibility in path selection.
maximum transmission unit
MTU is the largest unit of data that can be transmitted over a particular
interface type in one packet. The MTU can change over a network.
The navigation tree displays a view of all managed equipment, services, and
protocols, and allows you to navigate through these components.
network element
A physical device in a network, such as a 7750 SR, or a switch, such as the
7670 RSP.
A network topology is the layout of a network, which can include the way in
which elements in a network, such as nodes, are connected and how they
communicate.
network management system
A system that manages at least part of a network. An NMS is generally a
reasonably powerful and well-equipped computer such as an engineering
workstation. The NMS communicates with agents to help keep track of
network statistics and resources.
network operations center
Part of telecom architecture that is used to configure and monitor the
network and service elements.
