1.  The Network Management Framework

   The Internet-standard Network Management Framework consists of three
   components.  They are:

      STD16/RFC 1155 which defines the SMI, the mechanisms used for
      describing and naming objects for the purpose of management.
      STD16/RFC 1212 defines a more concise description mechanism, which
      is wholly consistent with the SMI.

      RFC 1156 which defines MIB-I, the core set of managed objects for
      the Internet suite of protocols.  STD17/RFC 1213, defines MIB-II,
      an evolution of MIB-I based on implementation experience and new
      operational requirements.

      STD15/RFC 1157 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) [7]
   defined in the SMI.  In particular, each object is named by 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
   descriptor, to also refer to the object type.
