                        Forum on Research in
                Distributed Computing and Open Systems
                        October 22-23, 1992
                        Ann Arbor, Michigan

The Center for Information Technology Integration (CITI) is pleased 
to announce a forum on research in Distributed Computing and Open 
Systems.  The Forum will take place in Ann Arbor, Michigan, on Thursday
and Friday, October 22 and 23, 1992.

CITI is. . .

. . . an applied research and development center at the University 
of Michigan that works jointly with corporate partners to broaden 
technological horizons and enhance the University's computing 
environment.  The results of these cooperative, sponsored projects 
are transferred to industry, government, and education.

Established in 1986 as part of the Information Technology Division, CITI 
continues toward its original goal of presenting a coherent distributed 
computing system to users at the University.  It is CITI's vision to 
provide information technology innovations that transform the way the 
University and the world do business.  

The CITI Forum will. . .

        * allow you to meet with CITI researchers and others who
          have gained practical experience in distributed computing
          and open systems concepts.

        * introduce you to the research and development CITI is doing.

        * provide you the opportunity to exchange information about 
          open systems and distributed computing.

        * demonstrate our current projects.

Our investigations over the last several years have given us extensive
experience in practical application of distributed computing and open
systems concepts in a large installation.  This forum will provide a 
comprehensive look at what we've done, where we are, and where we're
going.


Forum Highlights
----------------

Affiliates Update and CITI Overview 
  Theodore A. Hanss, Jr., director of the Center for Information 
    Technology Integration

Mobile Computing in Distributed Systems
  Peter Honeyman, Ph.D., research scientist and adjunct professor

   Portable computers have become commonplace, but the predominant 
   operating system remains MS-DOS, with no integrated support for 
   distributed computing. In this session you will learn about our 
   efforts to close that gap, using AFS on the Mach operating system.

Digitized Image Data Compression
  Frederick Remley, video technology specialist

   CITI is investigating various data compression techniques in order 
   to provide adequate performance when transferring large image 
   files across distributed systems. This session will describe
   techniques currently available for Macintosh and UNIX platforms, 
   methods used to transfer image files over networks, and storage 
   mechanisms for large files.

NetMod(tm): Network Modeling Made Easy
  Toby J. Teorey, Ph.D., senior staff member and associate professor

   Modeling complex networks can be a tedious, time-consuming task. 
   NetMod, developed at CITI, enables you to quickly and easily 
   generate numerous complex network configurations; quantitatively 
   evaluate the alternatives; and make better-informed implementation 
   decisions.

Deploying Distributed Computing on Campus
  William A. Doster, senior systems research programmer

   This presentation will discuss the current status of deployment 
   of the Institutional File System on the Ann Arbor campus of the 
   University of Michigan. We will address issues such as campus-wide 
   name space, system administration, and cost-recovery models.

Third-Party Authentication in the Institutional File System
  Jim Rees, senior systems research programmer

   The Institutional File System makes use of an intermediate 
   server to speed file caching.  This session will present our 
   solution to the problem of authenticating the intermediate server 
   to the central file server when the intermediate does not know 
   clients' private keys. 

Faster AFS
  Michael Stolarchuk, senior systems research programmer

   Investigation of the performance of AFS, when reading locally 
   cached files, showed an average read time of more than twice 
   that of the local file system. In this session you will hear 
   about that investigation and the modifications made to AFS so 
   that reads of locally-cached files perform within 10% of the 
   performance of the local file system.

Implementing Open Systems on AIX/ESA and MVS/ESA
  Lee Pearson, senior systems research programmer
  Bob Riddle,  senior systems research programmer

   These two sessions will discuss our efforts to integrate 
   the mainframe into our distributed environment, using the 
   Open Software Foundation's Distributed Computing Environment 
   as our base architecture. 

Massive AFS
  Charles J. Antonelli, Ph.D., research scientist and adjunct professor

   A critical problem facing AFS users is a chronic lack of disk storage 
   space for AFS files.  One promising approach marries mass storage 
   technology with AFS.  In this session you will learn about the issues, 
   proposed solutions, and current status of our work.

Disconnected AFS
  Larry Huston, graduate student research assistant

   CITI is modifying the AFS client to work without directly 
   communicating with the file servers.  In this session, you will 
   see our changes to the AFS cache manager to provide persistence 
   of important data structures, optimistic handling of cached data, 
   logging file system mutations, and reconciliation when the cache 
   manager is reconnected with a file server.

X.500 at the University of Michigan
  Timothy Howes, systems research programmer

   This session will describe the University's X.500 directory 
   service, containing information on over 70,000 U-M faculty, 
   staff, and students.  This service is integrated with campus
   e-mail and other information service environments (e.g. gopher).  
   We discuss configuration, performance enhancements, and general 
   experience implementing this service for campus.

Integrating PC LANs With the Institutional File System
  Brian D. Renaud, senior systems research programmer

   The University of Michigan has over 10,000 personal computers, 
   many of them on Local Area Networks (LANs).  To provide an 
   institution-wide share file store, we must integrate these LANs 
   with our distributed file system.  This talk will provide an 
   overview of our work to allow Novell, AFP (Macintosh), Banyan, 
   and NFS client machines to share the benefits of the Institutional 
   File System.

Netatalk:  AppleTalk and Distributed File Systems
  Thomas Hacker, systems research programmer

   Netatalk is an implementation of the AppleTalk protocol suite on BSD 
   UNIX and derivatives. Netatalk exploits currently existing TCP/IP 
   mechanisms such as sockets, and provides a programming interface to 
   the session and transport layers of AppleTalk. Netatalk exports both 
   AFS and UNIX local file system components as AFP volumes. This session 
   will acquaint you with Netatalk, currently used at the University of 
   Michigan to give campus Macintosh computers access to the AFS-based 
   Institutional File System.

Reception and Demonstrations at CITI

   A reception and demonstrations of CITI's current projects will take 
   place on Thursday evening, October 22 at the Center for Information 
   Technology Integration at 519 West William.  Software demonstrations 
   will include NetMod, Little Work (mobile computing), and OSF/DCE, 
   among others.
  
Network Operations Center Tour

   The University of Michigan's Ann Arbor campus is the site of the 
   Network Operations Center (NOC), the networking nerve center of 
   the National Science Foundation Network (NSFNET).  The NOC was 
   established and is currently maintained by Merit, a consortium of 
   nine of Michigan's publicly funded universities.  NSFNET links 
   super-computers across the country; MichNet, Merit's state-wide 
   network; and UMnet, the University of Michigan's campus network.  
   NSFNET, MichNet, and UMnet are all managed by Network Operations 
   staff. 

   As you tour the facility, you will see state-of-the-art equipment 
   monitoring these networks for outages, backups, failures and other 
   problems which require immediate action. Operator consoles and 
   impressive wall-size video screens display network availability 
   information.

Computing Center Tour

   The Computing Center building houses one of the largest of the 
   University of Michigan's three IBM mainframe computers. The ES/9000 
   Model 720 is water-cooled, with vector processing capabilities. The 
   Center has nearly 200 gigabytes of storage space and stores thousands 
   of magnetic tapes. The multi-processor computer runs the University's 
   Library System, Michigan Terminal System (MTS), Institutional File 
   System (IFS), and other operating systems.

U-M Walking Tour

   A self-guided walking tour of the University of Michigan's central 
   campus will direct you to areas of interest, such as: Angel Haven 
   Courtyard - the largest University student computing site; U-M 
   libraries; the Law Quad; Burton Memorial Tower - one of the best 
   known U-M landmarks; and the Dow Chemistry Building.
