1 Internet Engineering Task Force (IETF) Tony Hain

2 Agenda Organization Working Groups Documents Perspective

3 Agenda Organization Working Groups Documents Perspective

4 Role Historical developer of Internet-related protocols Consortium of individuals from Research, Education, Network operators, and Internet vendors

5 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)

6 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 Intrusion of middle-boxes Impact of unbridled creativity Wireless communications

7 Internet Engineering Steering Group (IESG) Mission Assure openness 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 (IPv6, routing)

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

9 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

10 Changed IETF composition and roles Attendance ActualAvg. Vendor/International Research/Education primarily US

12 Agenda Organization Working Groups Documents Perspective

13 Working groups in eight areas Internet Routing Transport Applications Security Operations and management General (Sub-IP)

14 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

15 Development process Bottom-up Working Group charters developed to support work people want to do Development process Working groups develop to consensus IESG reviews RFC editor publishes Specified in RFC 2026

16 Work model Primary work is conducted continuously on mail lists 3 face-to-face meetings per year Used 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

17 Agenda Organization Working Groups Documents Perspective

18 Two types of documents Internet drafts RFC - “request for comments”

19 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 Expire in 6 months

20 RFCs Historical archive Many kinds of documents Informational Historical Experimental Standards Proposed Draft Full Best current practice

21 Agenda Organization Working Groups Documents Perspective

22 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.

23 How IETF sees work divided Applications come from all over IETF Provides network infrastructure Tends to use interfaces defined by other bodies Wants to make sure the whole thing works HTML HTTP UDPRTP Ethernet ATMFrame RelayPPP Cellular Radio Telephony Signaling A variety of physical layers and interfaces Internet Protocol TCP MailSNMP Voice/ Video Data IEEE ETSI W3C ITU-T MPLS

24 IETF: infrastructure protocols Some link layer PPP Network layer IPv4, IPv6 Routing protocols Transport layer TCP, UDP, RTP Security services Transport layer security, IPSEC, ISAKMP Telephony signaling Signaling transport Quality support Differentiated services Integrated services

25 IETF: infrastructure applications SNMP management SMTP mail DNS name services LDAP directory services SSH virtual terminal protocol FTP file transfer HTTP web transfer And more...
