Abstract

   This memo defines the base SMIng (Structure of Management
   Information, Next Generation) language.  SMIng is a data definition
   language that provides a protocol-independent representation for
   management information.  Separate RFCs define mappings of SMIng to
   specific management protocols, including SNMP.
