A |
Agent
|
A system on the network that conforms
to SNMP and maintains a set of variables defined by SNMP that reflect
the conditions on the network. An agent can control access to its
variables by a manager. |
API
|
Application Programming Interface |
Application (or
Applet) |
A software product that uses
(includes) the SNMP component |
B |
Bean
|
A bean is a JavaBeans component. It
is an independent, reusable software module. Beans may be visible
objects, like AWT components, or invisible objects, like queues and
stacks. A builder/integration tool manipulates beans to create applets
and applications.
Note : This however is not strictly
true for the SNMP Manager bean which can
work only as an application due to
security restrictions that apply to applets. |
C |
Community
|
A grouping of Agents and Managers to
define domains for convenience of management. |
Component
|
A piece of software isolated into a
discrete, easily reusable structure. |
J |
Java
|
An object-oriented programming
language developed by Sun Microsystems. Java programs are compiled into
class files that can run on any computer platform that has a Java
Virtual Machine. |
JavaBeans
|
A portable, platform-independent
component model, based on Java. The model allows creation of small,
reusable, software components. A visual builder program combines
components from different sources to create applications quickly and
easily. |
M |
Manager
|
A system on the network that conforms
to SNMP and is responsible for monitoring / controlling the network
through get / set operations on variables maintained at agents. |
MIB (Management
Information Base) |
A set of variables that a host
running SNMP maintains. Managers can fetch or store into these
variables. MIB-2 refers to an extended management database of variables. |
O |
Object |
A network resource managed by the
Manager. It is mapped to one of the variables maintained by the Agent
and is represented by a unique Object Identifier. |
Object Identifier |
A unique name (identifier) for an
Object. The Object Identifier namespace is managed by ISO & CCITT to
ensure globally unique identifiers for objects. |
S |
SNMP (Simple
Network Management Protocol) |
A standard protocol to monitor hosts,
and networks to which they attach. It defines a set of variables that a
host (the Agent) must keep and specifies that all operations on the host
are a side effect of fetching or storing to the variables. |
