1. Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
STD 16/RFC 1155 [1] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management. STD
16/RFC 1212 [7] defines a more concise description mechanism,
which is wholly consistent with the SMI.
RFC 1156 [2] which defines MIB-I, the core set of managed objects
for the Internet suite of protocols. STD 17/RFC 1213 [4] defines
MIB-II, an evolution of MIB-I based on implementation experience
and new operational requirements.
STD 15/RFC 1157 [3] which defines the SNMP, the protocol used for
network access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2. Objects
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1) [5]
defined in the SMI. In particular, each object has a name, a syntax,
and an encoding. The name is an object identifier, an
administratively assigned name, which specifies an object type. The
object type together with an object instance serves to uniquely
identify a specific instantiation of the object. For human
convenience, we often use a textual string, termed the OBJECT
DESCRIPTOR, to also refer to the object type.
The syntax of an object type defines the abstract data structure
corresponding to that object type. The ASN.1 language is used for
this purpose. However, the SMI [1] purposely restricts the ASN.1
constructs which may be used. These restrictions are explicitly made
for simplicity.
The encoding of an object type is simply how that object type is
represented using the object type's syntax. Implicitly tied to the
