The Internet is as much a collection
of communities as a collection of technologies, and its success is largely
attributable to both satisfying basic community needs as well as utilizing the
community in an effective way to push the infrastructure forward. This
community spirit has a long history beginning with the early ARPANET.
The early ARPANET researchers worked
as a close-knit community to accomplish the initial demonstrations of packet
switching technology described earlier. Likewise, the Packet Satellite, Packet
Radio and several other DARPA computer science research programs were
multi-contractor collaborative activities that heavily used whatever available
mechanisms there were to coordinate their efforts, starting with electronic
mail and adding file sharing, remote access, and eventually World Wide Web
capabilities.
Each of these programs formed a
working group, starting with the ARPANET Network Working Group. Because of the
unique role that ARPANET played as an infrastructure supporting the various
research programs, as the Internet started to evolve, the Network Working Group
evolved into Internet Working Group.
In the late 1970s, recognizing that
the growth of the Internet was accompanied by a growth in the size of the
interested research community and therefore an increased need for coordination
mechanisms, Vint Cerf, then manager of the Internet Program at DARPA, formed
several coordination bodies - an International Cooperation Board (ICB), chaired
by Peter Kirstein of UCL, to coordinate activities with some cooperating
European countries centered on Packet Satellite research, an Internet Research
Group which was an inclusive group providing an environment for general
exchange of information, and an Internet Configuration Control Board (ICCB), chaired
by Clark. The ICCB was an invitational body to assist Cerf in managing the
burgeoning Internet activity.
In 1983, when Barry Leiner took over
management of the Internet research program at DARPA, he and Clark recognized
that the continuing growth of the Internet community demanded a restructuring
of the coordination mechanisms. The ICCB was disbanded and in its place a
structure of Task Forces was formed, each focused on a particular area of the
technology (e.g. routers, end-to-end protocols, etc.). The Internet Activities
Board (IAB) was formed from the chairs of the Task Forces.
It of course was only a coincidence
that the chairs of the Task Forces were the same people as the members of the
old ICCB, and Dave Clark continued to act as chair. After some changing
membership on the IAB, Phill Gross became chair of a revitalized Internet
Engineering Task Force (IETF), at the time merely one of the IAB Task Forces.
As we saw above, by 1985 there was a
tremendous growth in the more practical/engineering side of the Internet. This
growth resulted in an explosion in the attendance at the IETF meetings, and
Gross was compelled to create substructure to the IETF in the form of working
groups.
This growth was complemented by a
major expansion in the community. No longer was DARPA the only major player in
the funding of the Internet. In addition to NSFNet and the various US and
international government-funded activities, interest in the commercial sector
was beginning to grow. Also in 1985, both Kahn and Leiner left DARPA and there
was a significant decrease in Internet activity at DARPA. As a result, the IAB
was left without a primary sponsor and increasingly assumed the mantle of
leadership.
The growth continued, resulting in
even further substructure within both the IAB and IETF. The IETF combined
Working Groups into Areas, and designated Area Directors. An Internet
Engineering Steering Group (IESG) was formed of the Area Directors. The IAB
recognized the increasing importance of the IETF, and restructured the standards
process to explicitly recognize the IESG as the major review body for
standards.
The IAB also restructured so that
the rest of the Task Forces (other than the IETF) were combined into an
Internet Research Task Force (IRTF) chaired by Postel, with the old task forces
renamed as research groups.
