     Introduction to TCP/IP Internetworking,
     Dr. Douglas E. Comer, Purdue University
     Dr. Comer is a full professor of computer science at Purdue 
     University and a internationally known author of TCP/IP, Author of 
     numerous research papers and textbooks and head of several 
     networking research projects.  Dr. Comer designed and implemented 
     both the X25NET and Cypress networks and the Xinu operating system.  
     He is director of the Internetworking Research Group at Purdue, 
     editor-in-chief of the Journal of Internetworking, and former member 
     of the LAB.  Dr. Comer is also the North American editor of Software 
     Practice and Experience.
     The TCP/IP suite lets heterogeneous computer systems communicate 
     across interconnected networks using gateways and routers.  In this 
     tutorial, the instructor will describe IP addressing, subnetting, 
     and protocols including ARP, TCP, IP, FTP, TELNET, EGP and RIP.  You 
     will learn about concepts, principles, format, and the content of 
     the messages including IP datagrams and TCP segments.  Technical 
     terms and acronyms will be defined and examples of simple topologies 
     and routing strategies will be given.
     *  Organizations, documents, services, concepts
     *  Internet protocol:  IP addressing, address binding, APR, IP, 
        routing, fragmentation, ICMP

     SNA Interoperability Architecture and Implementations, 
     Wayne Clark, Cisco Systems, Inc.
     Mr. Clark, the SNA architect at Cisco Systems, Inc., has a master of 
     science degree in computer engineering from Santa Clara University.  
     Mr. Clark was previously a senior architect in the IBM Connectivity 
     Operations of 3Com Corporation and a leading developer of OEM SNA 
     software at Communications Solutions, Inc.
     IBM's Systems Network Architecture (SNA) is the networking 
     architecture of choice for many corporations.  The integration of 
     LANS and non-SNA networks with SNA has been popular for nearly seven 
     years.  In this tutorial you will learn about the interoperability 
     of SNA with TCP/IP and OSI from both architectural and product 
     perspectives.  The instructor will discuss a variety of products 
     from IBM and third-party vendors.
     *  Overview of the SNA architecture
     *  Description of IBM's advanced architectures APPC and APPN
     *  IBM directions for SNA interoperability

     The Simple Network Management Protocol (SNMP) for Internet Network 
     Dr. Jeffrey D. Case, SNMP
     Dr. Case is the author and co-author of several management standards 
     (including SNMP).  He is the principal author of the leading 
     vendor-independent reference implementation of SNMP-based agents and 
     manager of many vendors' SNMP implementations.
     The Simple Network Management Protocol (SNMP), designed for the 
     management of TCP/IP based internets, is a de facto standard.  The 
     use of SNMP is expanding to other applications and protocol suites.  
     In this tutorial, you will gain a thorough understanding of SNMP and 
     its underlying concepts and information about how to implement 
     systems based on SNMP.
     *  Introduction to network management and the network management 
     *  The SNMP protocol
     *  Abstract Syntax Notation One (ASN1) language, syntax and 
     *  Network management standardization process
     *  Standardization status, recent developments and the future

        to Management of TCP/IP based Internets
     Building Data Networks with Bridges and Routers, 
     Scott O. Bradner, Harvard University
     Mr. Bradner had been involved in data networking at Harvard since 
     the early day of the ARPANET.  He worked on the design of the 
     Harvard High-Speed Data Network (HSDN), the Longwood Medical Area 
     Network (LMAnet) and the New England Academic and Research Network 
     (NEARnet).  He is chairman of the technical subcommittees of both 
     LMAnet and NEARnet and of the IETF Benchmarking Methodology Working 
     Group.  Mr. Bradner is currently a consultant at Harvard and works 
     on the design and development of network-based applications.
     There has been an evolution in the design of data networks for the 
     university and enterprise-wide environments from bridged LANs to 
     complex internet-works.  In this tutorial you will learn about all 
     of the aspects involved in operating a modern data network, 
     including how to design and manage internetworks.
