                       HEMS VARIABLE DEFINITIONS

STATUS OF THIS MEMO

   This memo assigns instruction codes, defines object formats and
   object semantics for use with the High-Level Monitoring and Control
   Language, defined in RFC-1023.

   This memo is provisional and the definitions are subject to change.
   Readers should confirm that they have the most recent version of the
   memo.

   The authors assume a working knowledge of the ISO data encoding
   standard, ASN.1, and a general understanding of the IP protocol
   suite.

   Distribution of this memo is unlimited.

INTRODUCTION

   In other memos [RFC-1021, RFC-1022] the authors have described a
   general system for monitoring and controlling network entities; this
   system is called the High-Level Entity Management System (HEMS).
   This system permits applications to read and write values in remote
   entities which support a simple query processor.

   In this memo we standardize the language instruction codes, the
   objects which can be read or written, and the meanings of any
   constants stored in the objects.  There are three parts to this
   standardization: (1) the assignment of an ASN.1 tag to each value,
   (2) the definition of the external representation of the value (e.g.,
   INTEGER, OCTETSTRING, etc.), and (3) the definition of the meaning,
   or semantics of a value (e.g., what types of packets a particular
   packet counter actually tracks).

   This definition is provisional, and the authors hope that it will be
   expanded and improved as the community becomes more experienced with
   HEMS.  Readers with suggestions for additional object definitions, or
   improved definitions are encouraged to contact the authors.
