Practical Perspectives on OSI Networking (2 days) Christopher W. Moore and Marshall T. Rose The Wollongong Group, Inc. Overview Based on international cooperative work, it is commonly acknowledged that protocols based on the Open Systems Interconnection (OSI) model and promulgated by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) will eventually achieve dominance and enjoy even greater success than current networking technologies. This two day tutorial provides a practical perspective on the issues involved in developing and deploying OSI networks. Organized for those with a basic familiarity with OSI and with practical networking experience, the presentation will provide a more comprehensive understanding of the OSI Reference Model, OSI application and network services as well as a detailed understanding of various transition strategies which may be utilized in the realization of OSI networks from existing technology, in particular TCP/IP based networks. What You Will Learn You will achieve a thorough understanding of the technology involved in developing OSI applications, building OSI networks, and transiting to (or coexisting with) TCP/IP-based networks. Syllabus - OSI Application Services A discussion of current OSI applications and how they may be used to build new applications. Of interest to both System Administrators and Application Developers, topics include: - The OSI applications environment: concepts, service elements, and programmer tools - Use of standard OSI applications: the Directory, Message Handling Systems, and File Transfer, Access and Management - OSI Network Services A discussion of current OSI network and transport technologies and how they may be used to build networks. Of interest to Network Administrators, topics include: - The OSI network environment: concepts, building blocks, and connectivity - Comparison with relevant TCP/IP technology: complexity, administration, and performance - Transition from and Coexistence with TCP/IP A discussion of how existing, production TCP/IP-based networks may either transition to OSI, or coexist with OSI for maximal functionality. Of interest to both Network Administrators and Systems Administrators, topics include: - Motivation and Background: concepts, terminology, and metrics of comparison - Approaches: both protocol-based and service-based - Examples: scenarios for different environments Who Should Attend This tutorial is intended for professionals interested in planning, implementing, or managing OSI networks. A basic familiarity with networking and OSI is assumed. Detailed knowledge of the protocols is not required. Speakers Chris Moore is a Senior Software Engineer with The Wollongong Group, Inc., in Palo Alto, California, where his responsibilities include Directory Services as well as Message Handling Systems. He is involved with national and international working groups in these areas and presently serves as Vice Chairman of the U.S. National Bureau of Standards Implementors Workshops special interest group on Directory Services. Prior to joining Wollongong, Moore was a Systems Research Programmer with The University of Michigan Computing Center in Ann Arbor, Michigan. Marshall T. Rose is a Principal Software Engineer at The Wollongong Group, Inc., where he works on OSI protocols and transition strategies. He is the principal implementor of the ISO Development Environment (ISODE), an openly available implementation of the upper layers of the OSI protocol suite. He was co-author of RFC1006 (ISO Transport Services on top of the TCP), and was a member of the IFIP working group committee whose efforts led to RFC987 (Mapping between X.400 and RFC822). He is currently an advisor to the National Science Foundation, serving on its Network Technical Advisory Group. Rose received the Ph.D. degree in Information and Computer Science from the University of California, Irvine, in 1984.
