1ITU Telecom 99 Internet Standardization and the IETF Fred Baker IETF Chair Fred Baker IETF Chair
2ITU Telecom 99 www.ietf.org Thoughts I would like to address IETF History, Structure, and Procedure Whos who in the IETF Relations among standards bodies Who does what and why The big problems in the Internet Ongoing work How were going to solve them
3ITU Telecom 993 IETF History
4ITU Telecom 99 www.ietf.org 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
5ITU Telecom 99 www.ietf.org Changed IETF composition and roles 1000 1500 2000 2500 147 10131619222528313437404346 IETF Number Attendance ActualAvg.. Vendor/International Research/Education primarily US
6ITU Telecom 99 www.ietf.org Growth of international involvement in IETF Principle for placement of meetings: If I am doing the work, the meeting should sometimes be in my neighborhood But most work is done on mailing lists anyway… Non-US Meetings: 1990: Vancouver 1993: Amsterdam 1994: Toronto 1995: Stockholm 1996: Montreal 1997: Munich 1999: Oslo 2000: Adelaide

19ITU Telecom 99 www.ietf.org User Services Mission Provide documentation of IETF procedures to less involved communities 4 working groups Responsible use of the net Web elucidation of internet-related developments FYI updates User services
20ITU Telecom 99 www.ietf.org General Mission If we cant think of another place to put it, it goes here 1 working group Poisson: standing rules committee
21ITU Telecom 99 www.ietf.org Working group summary We have ~120 working groups Not all currently active Cover support of infrastructure for the commercial IP internet Not too worried about research network, unless they use the same technology
22ITU Telecom 9922 IETF Process
23ITU Telecom 99 www.ietf.org Membership IETF members are people As opposed to nations or companies Communications tend to be among people As opposed to working groups, boards, etc.
24ITU Telecom 99 www.ietf.org Fundamental working principle We do not worry about presidents and kings; We work by rough consensus and running code Dr. David C. Clark, Massachusetts Institute of Technology
25ITU Telecom 99 www.ietf.org Two types of documents Internet Drafts RFC - Request for Comments
26ITU Telecom 99 www.ietf.org 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 Types of drafts Working Group documents Submissions to working groups Individual Submissions
27ITU Telecom 99 www.ietf.org RFCs Historical Archive Many kinds of documents Informational Historical Experimental Standards Proposed, Draft, Full Best Current Practice
28ITU Telecom 99 www.ietf.org Development Process Bottom-up WG charters developed to support work people want to do Development Process Working groups develop IESG reviews RFC Editor publishes
29ITU Telecom 9929 Relations among standards bodies Anyone who likes legislation or sausage should watch neither one being made Baron von Bismarck Anyone who likes legislation or sausage should watch neither one being made Baron von Bismarck
30ITU Telecom 99 www.ietf.org Historical role of various standards bodies ITU-T IEEE ETSI W3C IETF Various marketing fora ATM Forum ADSL Forum MPLS Forum etc...
31ITU Telecom 99 www.ietf.org Institute of Electrical and Electronics Engineers (IEEE) Primarily link layer LAN standards http://ieee.org/ Especially LAN standards in 802 series IEEE 802.1 Bridging IEEE 802.3 CSMA/CD Networks (Ethernet) IEEE 802.5 Token Ring Networks
32ITU Telecom 99 www.ietf.org European Telecommunications Standards Institute (ETSI) European Telephony Standards http://www.etsi.org GSM Telephones WAP - Wireless Access Protocol
33ITU Telecom 99 www.ietf.org World Wide Web Consortium (W3C) Primarily Web services http://www.w3.org Headed by Tim Berners-Lee, inventor of HTML Developed HTML, XML, etc.
34ITU Telecom 99 www.ietf.org ITU Telecommunication Standardization Sector (ITU-T) Primarily related to telephony http://www.itu.int/ITU-T Consortium of Telephone companies Their traditional vendors
35ITU Telecom 99 www.ietf.org ITU-T Developments Various connector standards X.21, V.35, etc. Physical/Link layer network standards X.25, Frame Relay, ATM, SDH Telephony on specific substrate H.32x/H.310 Specific collaboration: H.323 uses IETF Data format Points of possible overlap with IETF IP/SDH MPLS IP/ATM ISO JTC1 voice control IP Telephony call signaling
36ITU Telecom 99 www.ietf.org IETF: Infrastructure protocols Some link layer PPP Network Layer IP4, IP6 Routing protocols Transport Layer TCP, UDP, RTP Security services Transport Layer Security, IPSEC, ISAKMP Telephony Signaling Signaling transport Quality support Differentiated Services Integrated Services

38ITU Telecom 99 www.ietf.org How IETF sees work divided Applications come from all over IETF Provides network infrastructure Tends to use interfaces defined by other bodies HTML HTTP UDPRTP EthernetATMFrame 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
39ITU Telecom 9939 So where is the Internet going? As for the future, your task is not to foresee, but to enable it. Antoine de Saint-Exupéry As for the future, your task is not to foresee, but to enable it. Antoine de Saint-Exupéry
40ITU Telecom 99 www.ietf.org IETF vision for the future Short term Internet as interconnected competing service providers Long term Internet as universal interconnect
41ITU Telecom 99 www.ietf.org Internet as interconnected competing service providers Dominated by Service Providers and Large enterprises A network of networks which have different policies and goals
42ITU Telecom 99 www.ietf.org Internet as universal interconnect IETF believes that the internet is the network of tomorrow Telephone companies seem to agree But how intelligent a network? Would like to see common procedures and protocols used throughout Minimize translation problems

45ITU Telecom 99 www.ietf.org When standards collide... Increasingly, convergence of Internet and PSTN networks causes collisions between the bodies that define their protocols and procedures The solution has to be in finding ways to: Not compete in standardization Focus on the problems remaining to be solved
46ITU Telecom 99 www.ietf.org The place of standards bodies Each has its place in the mix We need to work together on a global basis Competition between standards promotes inability to Share solutions to common problems Communicate among subscribers
