   with products or standard protocols, although specific experimental
   protocols may have to be developed, implemented and tested in order
   to gain understanding.

   The IRTF is a community of network researchers, generally with an
   Internet focus.  The work of the IRTF is governed by its Internet
   Research Steering Group (IRSG).  The chairman of the IRTF and IRSG is
   David Clark. The IRTF is organized into a number of Research Groups
   (RGs) whose chairs are appointed by the chairman of the IRSG.  The RG
   chairs and others selected by the IRSG chairman serve on the IRSG.

   These groups typically have 10 to 20 members, and each covers a broad
   area of research, pursuing specific topics, determined at least in
   part by the interests of the members and by recommendations of the
   IAB.

   The current members of the IRSG are as follows:

            David Clark         - Chairman
            Robert Braden       - End-to-End Services
            Douglas Comer       - Member at Large
            Deborah Estrin      - Autonomous Networks

RFC 1120                        The IAB                   September 1989


            Stephen Kent        - Privacy and Security
            Keith Lantz         - User Interfaces
            David Mills         - Member at Large

5. The Near-term Agenda of the IAB

   There are seven principal foci of IAB attention for the period 1989 -
   1990:

      1) Operational Stability
      2) User Services
      3) OSI Coexistence
      4) Testbed Facilities
      5) Security
      6) Getting Big
      7) Getting Fast

   Operational stability of the Internet is a critical concern for all
   of its users.  Better tools are needed for gathering operational
   data, to assist in fault isolation at all levels and to analyze the
   performance of the system.  Opportunities abound for increased
   cooperation among the operators of the various Internet components
   [RFC 1109].  Specific, known problems should be dealt with, such as
   implementation deficiencies in some version of the BIND domain name
   service resolver software.  To the extent that the existing Exterior
   Gateway Protocol (EGP) is only able to support limited topologies,
   constraints on topological linkages and allowed transit paths should
   be enforced until a more general Inter-Autonomous System routing
   protocol can be specified.  Flexibility for Internet implementation
   would be enhanced by the adoption of a common internal gateway
   routing protocol by all vendors of internet routers.  A major effort
   is recommended to achieve conformance to the Host Requirements RFCs
   which are to be published early in the fourth quarter of calendar
   1989.

   Among the most needed user services, the White Pages (an electronic
   mailbox directory service) seems the most pressing.  Efforts should
   be focused on widespread deployment of these capabilities in the
   Internet by mid-1990.  The IAB recommends that existing white pages
   facilities and newer ones, such as X.500, be populated with up-to-
   date user information and made accessible to Internet users and users
   of other systems (e.g., commercial email carriers) linked to the
   Internet.  Connectivity with commercial electronic mail carriers
   should be vigorously pursued, as well as links to other network
   research communities in Europe and the rest of the world.

   Development and deployment of privacy-enhanced electronic mail
   software should be accelerated in 1990 after release of public domain



Cerf                                                            [Page 7]

   software implementing the private electronic mail standards [RFC
   1113, RFC 1114, and RFC 1115].  Finally, support for new or enhanced
   applications such as computer-based conferencing, multi-media
   messaging and collaboration support systems should be developed.

   The National Network Testbed (NNT) resources planned by the FRICC
   should be applied to support conferencing and collaboration protocol
   development and application experiments and to support multi-vendor
   router interoperability testing (e.g., interior and exterior routing,
   network management, multi-protocol routing and forwarding).

   With respect to growth in the Internet, architectural attention
   should be focused on scaling the system to hundreds of millions of
   users and hundreds of thousands of networks.  The naming, addressing,
   routing and navigation problems occasioned by such growth should be
   analyzed.  Similarly, research should be carried out on analyzing the
   limits to the existing Internet architecture, including the ability
   of the present protocol suite to cope with speeds in the gigabit
   range and latencies varying from microseconds to seconds in duration.

   The Internet should be positioned to support the use of OSI protocols
   by the end of 1990 or sooner, if possible.  Provision for multi-
   protocol routing and forwarding among diverse vendor routes is one
   important goal.  Introduction of X.400 electronic mail services and
   interoperation with RFC 822/SMTP [RFC 822, RFC 821, RFC 987, RFC
   1026] should be targeted for 1990 as well.  These efforts will need
   to work in conjunction with the White Pages services mentioned above.
   The IETF, in particular, should establish liaison with various OSI
   working groups (e.g., at NIST, RARE, Network Management Forum) to
   coordinate planning for OSI introduction into the Internet and to
   facilitate registration of information pertinent to the Internet with
   the various authorities responsible for OSI standards in the United
   States.

Security Considerations

   Finally, with respect to security, a concerted effort should be made
   to develop guidance and documentation for Internet host managers
   concerning configuration management, known security problems (and
   their solutions) and software and technologies available to provide
   enhanced security and privacy to the users of the Internet.
