Three New Documents

[Steve Hardcastle-Kille <[e-mail]>]

Three new drafts from the SPP folks.   These will form the baseis of the
second OSI-DS session in Columbus.

          Charting Networks in the Directory
          Glenn Mansfield  
	  Thomas Johannsen  
	  Mark Knopper
          February 1993
          Abstract:
          There is a need for a framework wherein the  infrastructural
          and service related information about communication networks
          can be made accessible from all places and at all times in a
          reasonably  efficient  manner  and with reasonable accuracy.
          This document presents a model in which a communication net-
          work  with  all  its related details and descriptions can be
          represented in the X.500 Directory. Schemas of  objects  and
          their  attributes  which  may  be  used for this purpose are
          presented.  The model envisages physical objects and several
          logical abstractions of the physical objects.

          Representing IP Information in the X.500 Directory
	  Thomas Johannsen  
          Glenn Mansfield  
          February 1993
          Abstract:
          This document describes the  objects  necessary  to  include
          information  about  IP  networks and IP numbers in the X.500
          Directory. It extends the work  "Charting  networks  in  the
          Directory" [ND] where a general frame work is presented  for
          representing networks in the Diretory by applying it  to  IP
          networks.  This  application of the Directory is intended to
          support the work of IP network assigning authorities,  NICs,
          as  well  as  other applications looking for a mapping of IP
          numbers to data of related networks.

          Optimizing Document Retrieval by Using the X.500 Directory
	  Thomas Johannsen  
          Glenn Mansfield  
          February 1993
          Abstract:
          Copying documents from public  fileservers  (like  anonymous
          ftp)  is widely used in the Internet and is known to cause a
          great amount of long-distance network traffic. This  traffic
          can  be reduced by careful selection of the fileserver site.
          Connections should be optimized with regard to network  load
          and other management parameters.

          Our paper proposes a method to allow a reasonable  selection
          among  given  retrieval  choices. Selection will be based on
          network connection  properties  (such  as  bandwidth,  costs
          etc.). These properties are stored in the X.500 Directory as
          part of an effort to represent networks.

          Furthermore, this paper describes a simple way to  represent
          filestores and their contents' in the X.500 Directory. Thus,
          queries for files can be done in the Directory.  New  object
          classes and attribute types are presented.

------------------------------------------------------------------------




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
To: [e-mail]
Subject: Anything you like

request: osi-ds
topic: scope.txt	


Files are available in Text, Postscript or both.   
    FILENAME.txt for plain text format
    FILENAME.ps  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
 OSI-DS-MINUTES nnn

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 uk.ac.ucl.cs, 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)
