1 Internet Standardization and the IETF Fred Baker IETF Chair 1

2 Thoughts I would like to address IETF History, Structure, and Procedure Who s who in the IETF Relations among standards bodies Who does what and why The big problems in the Internet Ongoing work How we re going to solve them 2

3 IETF History 3

4 Internet Engineering Task Force (IETF) Historical developer of internet-related protocols Consortium of individuals from Research, Education, Network operators, and Internet vendors 4

5 Attendance 2500 Changed IETF composition and roles Research/Education primarily US Vendor/International -500 IETF Number Actual Avg.. 5

6 Principle for placement of meetings: Growth of international involvement in IETF 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 6

7 IETF Growth by Country Germany Sweden Other 1.9% 1.8% France 2.0% Netherlands 2.2% Canada 3.1% UK 4.2% JAPAN 7.6% 5.5% USA 71.6% December Countries Netherlands 3% Canada 3% France 4% Finland 4% Germany 5% Norway 5% UK 6% July 1999 Italy Other 2% 8% Sweden 6% 33 Countries USA 48% Japan 6% 7

8 IETF Structure 8

9 IETF structures and key forums Internet Architecture Board Internet Engineering Steering Group Working groups in eight areas 9

10 Internet Architecture Board (IAB) Mission Supreme court on appeals of IESG decisions Think tank for future internet activities Recent activities Really worried right now about End to end model of the internet Impact of wireless communications 10

11 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 Currently drawn into a privacy debate Better addressed in area activities 11

12 Working groups in eight areas Internet Routing Transport Applications Security Network operations and management User services General 12

13 Mission Internet IP/foo specifications Interface configuration and management IP developments, mostly IP6 15 working groups Interface mibs, dnsind, dhcp, ipng, IP/cable ADSL IEEE 1394, PPP, ion,... 13

14 Routing Mission So how does a packet get there, anyway? 17 working groups BGMP, MPLS, MSDP, manet, vrrp, bgp, ospf, idmr, SNA... 14

15 Transport Mission QoS management End to End delivery issues Telephony issues 22 working groups Diff-serv, int-serv, megaco, sigtran, audio/video, rap,... 15

16 Applications Mission Infrastructure applications development and extension Historical applications 26 working groups Web, LDAP, edi, nntp, smtp, ftp, telnet, calendaring, mime, etc. 16

17 Security Mission Developing procedures and protocols to enhance security in the internet 15 working groups Ipsec, pki, transport layer security, web transaction security, pgp, one time password, etc... 17

18 Mission Network Operations and Management (O&M) Making sure there is operational clue looking at the specifications and procedures Network management (used to mean SNMP) Making those two talk with each other Y2k 20 working groups Snmpv3, policy, various mibs, agent extensibility... Ngtrans, year2000, mbone deployment, routing policy system,... 18

19 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 19

20 General Mission If we can t think of another place to put it, it goes here 1 working group Poisson: standing rules committee 20

21 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 21

22 IETF Process 22

23 Membership IETF members are people As opposed to nations or companies Communications tend to be among people As opposed to working groups, boards, etc. 23

24 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 24

25 Two types of documents Internet Drafts RFC - Request for Comments 25

26 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 26

27 RFCs Historical Archive Many kinds of documents Informational Historical Experimental Standards Standards Proposed, Draft, Full Best Current Practice 27

28 Development Process Bottom-up WG charters developed to support work people want to do Development Process Working groups develop IESG reviews RFC Editor publishes 28

29 Relations among standards bodies Anyone who likes legislation or sausage should watch neither one being made Baron von Bismarck 29

30 Historical role of various standards bodies ITU-T IEEE ETSI W3C IETF Various marketing fora ATM Forum ADSL Forum MPLS Forum etc... 30

31 Institute of Electrical and Electronics Engineers (IEEE) Primarily link layer LAN standards Especially LAN standards in 802 series IEEE Bridging IEEE CSMA/CD Networks (Ethernet) IEEE Token Ring Networks 31

32 European Telecommunications Standards Institute (ETSI) European Telephony Standards GSM Telephones WAP - Wireless Access Protocol 32

33 World Wide Web Consortium (W3C) Primarily Web services Headed by Tim Berners-Lee, inventor of HTML Developed HTML, XML, etc. 33

34 ITU Telecommunication Standardization Sector (ITU-T) Primarily related to telephony Consortium of Telephone companies Their traditional vendors 34

35 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 35

36 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 36

37 IETF: Infrastructure applications SNMP management SMTP mail DNS name services LDAP Policy services telnet virtual terminal protocol FTP file transfer HTTP Web transfer and more... 37

38 IEEE How IETF sees work divided Applications come from all over IETF W3C Mail HTML HTTP SNMP Voice/ Video Data TCP UDP RTP Internet Protocol Ethernet ATM Frame Relay PPP A variety of physical layers and interfaces ITU-T Provides network infrastructure Telephony Signaling MPLS Cellular Radio ETSI Tends to use interfaces defined by other bodies 38

39 So where is the Internet going? As for the future, your task is not to foresee, but to enable it. Antoine de Saint-Exupéry 39

40 IETF vision for the future Short term Internet as interconnected competing service providers Long term Internet as universal interconnect 40

41 Internet as interconnected competing service providers Dominated by Service Providers and Large enterprises A network of networks which have different policies and goals 41

42 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 42

43 Growth of IP Traffic Information search/access Subscription services/ Push Rel. Bit Volume Traffic Projections for Voice and Data Data (IP) Conferencing/ multimedia Video/imaging From 2000 on, 80% of Service Provider Profits Will Be Derived from IP-Based Services.

44 In summary... I came, I saw, I couldn t believe my eyes Julius Caesar, as portrayed in Asterix in Britain 44

45 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 45

46 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 46
