TRANSCRIPT
Role
Historical developer of Internet-related protocolshttp://www.ietf.org
Consortium of individuals from Research, Education, Network operators, and Internet vendors
Organization
Internet Society (ISOC) – Legal entity, funding & insurance
Internet Architecture Board (IAB) – Architecture overview, Process appeals
Internet Engineering Steering Group (IESG) – Process Management
Working Groups (over 100 in 8 areas)
Internet Architecture Board (IAB)
MissionOversight of IETF, IRTF, IANA, liaisonsThink tank for future Internet activities
Recent activitiesReally worried right now about
Integrity of the infrastructureIntrusion of middle-boxesImpact of unbridled creativityWireless communications
Internet Engineering Steering Group (IESG)
MissionAssure openness and adherence to processWorking group chartering and management“Quality assurance” on specifications
Activities and trendsMaking sure mobile networks are part of the InternetTrying to grow the network (IPv6, routing)
Membership
IETF members are individualsAs opposed to nations or companies
Communications tend to be among individualsAs 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.

Working group summary
We have more than 100 working groups Not all currently active
Maintain the IPv4 Internet
Enable the IPv6 Internet
Create the mobile Internet
Make all the Internet useful and secure
Development process
Bottom-upWorking Group charters developed to support work people want to do
Development processWorking groups develop to consensus
IESG reviews
RFC editor publishes
Specified in RFC 2026
Work model
Primary work is conducted continuously on mail lists
3 face-to-face meetings per yearUsed for issues that are not resolved via email
7-10 parallel meetings in 1 to 2 ½ hour segments
Mon-Thurs 9am to 10pm
Orientation session Sun 12-4
Internet drafts
Most analogous to ITU “contributions” and “working papers”
Not necessarily work itemsHalf of all Internet drafts are simply documents people have chosen to postNine out of ten I-Ds do NOT result in RFCs
Types of draftsWorking group documentsSubmissions to working groupsIndividual submissions
Expire in 6 months
RFCs
Historical archive
Many kinds of documents

Best current practice
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 usA larger Internet creates larger markets.Larger markets create cheaper products.Cheaper products create more end-user value.
How IETF sees work divided
Applications come from all over
