IETF structure

IETF structures and key
forums
• Internet Architecture Board
• Internet Engineering Steering Group
• Working groups in eight areas

Internet Architecture Board
(IAB)
• Mission
Oversight of IETF, IRTF, IANA, liaisons
Think tank for future Internet activities
• Recent activities
Really worried right now about
Integrity of the infrastructure
Impact of unbridled creativity
Wireless communications

Internet Engineering Steering
Group (IESG)
• Mission
Assure open-ness and adherence to process
Working group chartering and management
“Quality assurance” on specifications
• Activities and trends
Making sure mobile networks are part of the Internet
Trying to grow the network (v6, routing)

Working group summary
• We have more than 100 working groups
Not all currently active
• Maintain the v4 Internet
• Enable the v6 Internet
• Create the mobile Internet
• Make all the Internet useful and secure

IETF process
12
Membership
• IETF members are people
As opposed to nations or companies
• Communications tend to be among
people
As opposed to working groups, boards,
etc.
Have trouble understanding “liaison”

Fundamental working
principle
“We reject kings, presidents, and
voting.
We believe in rough consensus
and running code.
Dr. David C. Clark,
Massachusetts Institute of Technology

Fundamental perspective of
enlightened self-interest
• There is no one organization or company which
has a corner on intelligence or expertise
Good ideas that help our markets come from everywhere
and anywhere
• Growing the Internet is good for all of us
A larger Internet creates larger markets.
Larger markets create cheaper products.
Cheaper products create more end-user value.

Two types of documents
• Internet drafts
• RFC - “request for comments”
Internettdagerna Oct 24, 2000
www.ietf.org
16
Internet drafts
• Most analogous to ITU “contributions”
and “working papers”
Not necessarily work items
Half of all Internet drafts are simply documents
people have chosen to post
Nine out of ten I-Ds do NOT result in RFCs
• Types of drafts
Working group documents
Submissions to working groups
Individual submissions

17
RFCs
• Historical archive
• Many kinds of
documents
• Standards
Informational
Proposed, draft, full
Historical
Best current practice
Experimental
Standards

Development process
• Bottom-up
Working Group charters developed to
support work people want to do
• Development process
Working groups develop
IESG reviews

Relations among
standards bodies
“Anyone who likes legislation or
sausage should watch neither one
being made”
Baron von Bismarck

• IETF
Provides network infrastructure
Tends to use interfaces defined by other bodies
Wants to make sure the whole thing works
