Three new drafts from the SPP folks. These will form the baseis of the second OSI-DS session in Columbus. Steve OSI-DS 37 osi-ds-37-00.ps osi-ds-37-00.txt 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. OSI-DS 38 osi-ds-38-00.ps osi-ds-38-00.txt 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. OSI-DS 39 osi-ds-39-00.ps osi-ds-39-00.txt 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: info-server@cs.ucl.ac.uk 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)
