IETF structures and key forums
IETF structures and key forums
• Internet Architecture Board
• Internet Engineering Steering Group
• Working groups in eight areas
8Internettdagerna Oct 24, 2000 www.ietf.org
Internet Architecture Board (IAB)
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
9Internettdagerna Oct 24, 2000 www.ietf.org
Internet Engineering Steering Group (IESG)
Internet Engineering Steering Group (IESG)
• MissionAssure open-ness and adherence to process
Working group chartering and management
“Quality assurance” on specifications
• Activities and trendsMaking sure mobile networks are part of the Internet
Trying to grow the network (v6, routing)

Working group summaryWorking 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
13Internettdagerna Oct 24, 2000 www.ietf.org
MembershipMembership
• 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
Fundamental working principle
“
”
We reject kings, presidents, and voting.
We believe in rough consensus and running code.

Fundamental perspective of enlightened self-interest
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.
16Internettdagerna Oct 24, 2000 www.ietf.org
Two types of documentsTwo types of documents
• Internet drafts
• RFC - “request for comments”
17Internettdagerna Oct 24, 2000 www.ietf.org
Internet draftsInternet 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 draftsWorking group documents
Submissions to working groups
Individual submissions
18Internettdagerna Oct 24, 2000 www.ietf.org
