[comp.protocols.iso] System Title

barns@GATEWAY.MITRE.ORG (02/15/90)

There is a thing in OSI called a System Title.  It is defined (in 7498-3,
I believe) as (essentially) the unique name of a particular Real Open
System - sort of like a host name.  I would like to know anything
more concrete about them that is knowable.  For example:

   Does any standard define what a system title looks like in any
   identifiable frame of reference (ASN.1, bit encodings, ...)?

   Is there any specific OSI use to which the System Title is (or will
   be) put?  Network management seemed like a possibility, but I was
   not able to pin this down clearly with moderate effort.  I found in
   the RFC1066 Internet TCP/IP MIB something called sysObjectID whose
   value seems to conceptually resemble a System Title, and its
   definition defines an abstract representation and thus an encoding
   of this title-like thing, but this does not give me much of a clue
   about whether System Titles are envisioned as things that one will
   use in OSI NM.

It seems plausible that a System Title would be represented as an
Object Identifier, but I haven't even found an explicit statement to
that effect.  Does anyone out there have any pointers to useful
information?

I've been wondering the same thing. My modest researches have not turned up
much.

The System Title does seem to appear in OSI Management, as "SystemID". The
reference is:


	SMI - Part 2
	2nd DP 10165 - 2   (JTC1 / SC21 / N 4072)

In this document, the syntax is given as a Graphic String.

However, like you, I think Object Identifier would be better. For one thing,
System Title as an object identifier would mean that Application
Process Titles can be arcs taken off the System Title node
in the Object Identifier tree. (Should System Title then have a "sequence of
RDNs" format as well, as AP-Title does?  AP-Title is defined in (draft?)
addendum to ASCE protocol, ISO 8650, "as a result of Defect Report
8650/004".)


Any comments, anyone?
