A convergence side
effect
By Scott Bradner
Network World, 9/21/98
Convergence is all
the rage these days. IP is taking over the
telecommunications
world.
Voice, video and
data are all seen as migrating to the Internet or, at
least, are expected
to be carried over IP networks. In the past few
months, there have
been major announcements from many of the
large long-distance
carriers, telephone equipment suppliers, cable TV
companies, ISPs and
data network equipment vendors about the
wonderful products
and services that will soon be changing our
world. While not
everyone subscribes to the cult of IP inevitability, it
sure seems to be
gaining in popularity.
The
telecommunications area is rich in standards organizations. In
addition to the
internationally chartered traditional standards
organizations such
as the International Telecommunication Union
(www.itu.int) and
the International Organization for Standardization
(www. iso.ch), there
are a number of regional bodies, many
nationally based
organizations and consorts such as the ATM Forum.
If one can assert
that 10 years is a history, the Internet Engineering
Task Force (IETF)
has been the primary standards development
organization for
IP-related protocols. But there are quite a few other
organizations that
are starting to think they should play a role.
Over the years, the
IETF has established relationships with a number
of other standards
bodies. The IETF has liaisons with the ATM
Forum and with
different Study Groups within the ISO.
The relationships
between the IETF and other standards organizations
have been congenial
but have generally not been all that close over the
past few years. I
expect the relationships to get closer, though
sometimes more
contentious as the convergence bandwagon gains
momentum. The groups
will get closer because the various
organizations are
becoming ever more dependent on each others'
technology. However,
the relationships will grow more contentious
when two or more
organizations are working on the same problem.
Cooperation among
organizations can work very well as was shown
in the joint
IETF-ITU Internet-FAX effort earlier this year. Such
cooperation has just
been reinforced by the development of the joint
IETF-ITU process
document announced last week.
In the ideal case,
two or more organizations will agree on one
standards document,
processed by one of the organizations and
referred to by the
others. Unfortunately this will not always happen.
There will be cases
in which organizations will disagree on the
definition of or
technical solution to a particular problem. The result
will be competing
standards. While competing standards are not ideal,
the situation is
better than technological stagnation. The market will
decide which
solution better meets actual user requirements.
After years of being
mostly ignored by the traditional standards
community and
returning the favor, the IETF must now figure out
how to work with
others without compromising the quality of its
work.
Disclaimer: It is
rare that Harvard has the problem of being ignored,
but I know of no
Harvard statement on the above topic.
