The Vocabulary
This section lists the definitions of the terms most frequently used when
speaking of or about Network Management. The intent of this information
is to help people understand the many acronyms and words that are
used in Network Management.
You can add to this list if you think
it is missing something. (Since I am just starting this section, it
is definitely missing a lot!).

- Asynchronous Transfer Mode
-
A high speed connection oriented switching and multiplexing
technology that uses 53 byte cells (5 byte header, 48 byte
payload) to transmit different types of traffic
simultaneously, including voice, video and data. It is
asynchronous in that information streams can be sent
independently without a common clock.
(Data Communications, Dec 1994)

- Abstract Syntax Notation One
-
The OSI language for
describing abstract entities
by using macros that build on simpler entities. The primary
advantage of this syntax is that it is not dependent upon the
underlying hardware.
- ASN.1
-
See: Abstract Syntax Notation One
- CMIP
-
Common Network Information Protocol, an application level
protocol, specified by OSI, for network management.
- EMS
-
Element Management System
An EMS manages a specific portion of the network. For
example with a SunNet Manager, an SNMP management
application, is used to manage SNMP manageable elements.
Element Managers may manage async lines, multiplexers,
PABX's, proprietary systems or an application.

- Fault Management
-
Fault management is the detection of a problem, fault
isolation and correction to normal operation.

- ISDN
-
Integrated Services Digital Network - A switched digital transmission
service provided by a local telco's switching office. Uses same
copper as analog service so is practical for home, small office,
school applications. Available in BRI (2 64Kb data channels
1 signaling channel) or PRI (23 bearer(data/voice) channels
1 signaling channel)
- LMMP
-
LAN MAN Management Protocol, an IEEE standard for network
management.
- Managed Objects
-
Managed Objects are the devices, systems and/or anything
else, e.g., protocols or applications requiring some form
of monitoring and management.

Doug Stevenson's white paper on
Network Management)
- MIB
-
Management Information Base. The objects
that are available in a managed system. The information is
represented in Abstract Syntax Notation 1 (ASN.1)
- MoM
-
Manager of Managers System
MoM systems integrate together the information associated
with several element management systems, usually performing
alarm correlation between
EMS's.
