                      3: Issues in Transition and Coexistence for TCP/IP to OSI  (1/2 day)
                      4: 
                      5: Dr. Marshall T. Rose

                      8: Overview
                      9: 
                     10:      The U.S. DoD Internet suite of protocols (commonly known as TCP/IP)
                     11:      is the de facto open (non-proprietary) standard for
                     12:      computer-communications in multi-vendor and multi-administration
                     13:      networks.  TCP/IP has enjoyed unprecedented success as the open
                     14:      systems solution of choice for inter-connecting networks and hosts.
                     15:      However based on international cooperative work, it is commonly
                     16:      acknowledged that protocols based on the Open Systems
                     17:      Interconnection (OSI) model and promulgated by the International
                     18:      Organization for Standardization (ISO) will eventually achieve
                     19:      dominance and enjoy even greater success than TCP/IP.
                     20: 
                     21:      Although previously an "academic" problem, the widespread
                     22:      investment in TCP/IP-based systems has made practical solutions to
                     23:      transition and coexistence an overwhelming concern:  organizations
                     24:      using TCP/IP protocols today will be less willing to adopt OSI
                     25:      protocols tomorrow unless interruption of production facilities is
                     26:      minimized and the underlying investment is protected.
                     27: 
                     28: 
                     29: What You Will Learn
                     30: 
                     31:      You will achieve a thorough understanding of the technology
                     32:      involved when interconnecting TCP/IP-based systems to OSI-based
                     33:      systems.

                     36: Syllabus
                     37: 
                     38:      - Motivation: the need for transition and coexistence
                     39: 
                     40:      - Background: concepts, terminology, and metrics of comparison
                     41: 
                     42:      - Protocol-based approaches: dual-stacks, application gateways, and
                     43:        transport gateways; discussion of existing implementations
                     44: 
                     45:      - Re-defining the problem: understanding the difference between
                     46:        transition and coexistence
                     47: 
                     48:      - Service-based approaches: transport-service bridges, and network
                     49:        tunnels; discussion of existing and planned implementations
                     50: 
                     51:      - Examples: scenarios for different environments; the DoD OSI

                     56: 
                     57:      This tutorial is intended for professionals interested in planning,
                     58:      implementing, or managing environments containing both TCP/IP and
                     59:      OSI implementations.  Although detailed knowledge of neither TCP/IP
                     60:      nor OSI is required, basic familiarity with both protocols suites
                     61:      is assumed.  No knowledge of protocol translation issues is
                     62:      required.

                     68:      Group where he works on OSI protocols and transition strategies.
                     69:      He is the principal implementor of the ISO Development Environment
                     70:      (ISODE), an openly available implementation of the upper layers of
                     71:      the OSI protocol suite.  He was co-author of RFC1006 (ISO Transport
                     72:      Services on top of the TCP), and was a member of the IFIP working

                     74:      and RFC822).  He is currently an advisor to the National Science
                     75:      Foundation, serving on its Network Technical Advisory Group.  He is
