  3. Internet Engineering Task Force (IETF) • Historical developer of Internet-related protocols • Http://www.ietf.org • Consortium of individuals from • Research, Education, Network operators, and Internet vendors

  6. IETF structure 6

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

  8. 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

  9. 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)

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

  11. 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

  12. IETF process 12

  13. 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”

  14. “ ” 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

  15. 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.

  16. Two types of documents • Internet drafts • RFC - “request for comments”

  17. 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

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

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

  20. Relations among standards bodies “Anyone who likes legislation or sausage should watch neither one being made” Baron von Bismarck 20

  21. 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 IETF: infrastructure protocols

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

  23. How IETF sees work divided W3C HTML Voice/ Video Data Telephony HTTP Mail SNMP Signaling • 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 UDP RTP TCP Internet Protocol IEEE MPLS Ethernet ATM Frame Relay PPP ETSI A variety of physical layers and interfaces Cellular Radio ITU-T
