Description of Working Group:
The TUBA Working Group will work on extending the Internet Protocol
suite and architecture by increasing the number of end systems which
can be effectively addressed and routed. The TUBA effort will expand
the ability to route Internet packets by using addresses which support
more hierarchy than the current Internet Protocol (IP) address space.
TUBA specifies the continued use of Internet Transport Protocols, in
particular TCP and UDP, but encapsulated in ISO 8473 (CLNP) packets.
This will allow the continued use of Internet application protocols
such as FTP, SMTP, Telnet, etc. An enhancement to the current system
is mandatory due to the limitations of the current 32 bit IP
addresses. TUBA seeks to upgrade the current system by a transition
from the use of the Internet Protocol version 4 to ISO/IEC 8473 (CLNP)
and the corresponding large Network Service Access Point address
space.
In addition to protocol layering issues and ``proof of concept'' work,
the TUBA approach will place significant emphasis on the engineering
and operational requirements of a large, global, multilateral public
data network. TUBA will work to maximize interoperatability with the
routing and addressing architecture of the global CLNP infrastructure.
The TUBA Working Group will work closely with the IETF NOOP and
IPRP-for-IP Working Groups to coordinate a viable CLNP based Internet
which supports the applications which Internet users depend on such as
Telnet, FTP, SMTP, NFS, X, etc. The TUBA Working Group will also work
collaboratively with communities which are also using the CLNP
protocol, and will consider issues such as interoperability,
applications coexisting on top of multiple transports, and the
evolution of global public connectionless datagram networks, network
management and instrumentation using CLNP and TUBA, and impact on
routing architecture and protocols given the TUBA transition.
The TUBA Working Group will consider how the TUBA scheme will support
transition from the current IP address space to the future NSAP
address space without discontinuity of service, although different
manufacturers, service providers, and sites will make the transition
at different times. In particular, the way in which implementations
relying on current 32 bit IP addresses will migrate must be
considered. TUBA will ensure that IP addresses can be assigned, for
as long as they are used, independently of geographical and routing
considerations. One option is to embed IP addresses in NSAP addresses,
possibly as the NSAP end-system identifier. Whatever scheme is chosen
must run in a majority of *-GOSIPs and other NSAP spaces. The TUBA
strategy will require a new mapping in the DNS from NAMEs to NSAP
addresses.
The rationale RFC (RFC-1347) documents issues of transition and
coexistence, among unmodified ``IP'' hosts and hosts which support
``TUBA'' hosts. Hosts wishing full Internet connectivity will need to
support TUBA.
Goals and Milestones:
Done Post Initial TUBA rational and discussion as an RFC. (RFC 1347)
Done Post the Initial TUBA DNS specification. (RFC 1348)
Done Review and approve the Charter.
Done Post the TUBA CLNP profile as an Internet-Draft.
Done Post an Routing and Addressing specification as an Internet-Draft,
coordinated with the Network OSI Operations Working Group and the
IDRP for IP Working Group.
Nov 92 Post a summary report on TUBA deployment in the Internet.
Done Present the results of Working Group deliberations at the November
IETF meeting.
Nov 92 Post an Internet-Draft on the changes required to Internet
applications affected by the deployment of TUBA.
Nov 92 Post an Internet-Draft covering the methodologies, instrumentation,
address administration, routing coordination and related topics.
Done Post as an Internet-Draft a revision to RFC 1347 reflecting lessons
learned in the Working Group deliberation.
