This is for the discussion on lightweight directory protocols.  I hope to
discus both SOS, and the three SOS-based directory protocols I propose in
the appendices.

I'm submitting this as an I-D, as it has wider scope.


        The Simple OSI Stack
        S.E. Hardcastle-Kille
        March 992
This document specifies a mapping of protocols defined by the Abstract
Service Description Conventions onto Connection Oriented Transport
Service, Connectionless Transport Service, TCP, and UDP [MHS88b].
This mapping will support all ROS (Remote Operation Service) based
protocols, such as directory, both with and without use of RTS
(Reliable Transfer Service), and all of the X.400 services
[ISO88, CCI88, MHS88a].

Four example applications of the Simple OSI Stack (SOS) are given in
appendices.  These are all ``real'' examples, which will are quite
likely to evolve into formal specifications.  They are intended to
show that specification of SOS applications is very straightforward
and useful.  These examples will be dropped from future versions of
this document, and perhaps be replaced by artificial examples.

The following topics  may be obtained from the info-server
using a request in the form:
        request: osi-ds
        topic: <one of topics the below>

For example:

From: Joe.Soap@somedomain
Subject: Anything you like

request: osi-ds
topic: scope.txt	

Files are available in Text, Postscript or both.   
    FILENAME.txt for plain text format  for postscript

Note that not all the files are available in all the formats.

All documents are numbered, in the form OSI-DS nnn or

The files are also available by FTP, NIFTP, and  FTAM.

FTP to CS.UCL.AC.UK, username anonymous and your own name as password
		cd osi-ds; 

FTAM to bells, computer science, university college london, gb 
   username = anon, no password

NIFTP to, binary mode, username  =  guest,
     password  =  (Your  mail address in the form user@site)
     filenames should be prepended with <OSI-DS> (Note that the
     angle brackets and capital letters are vital)
