1 hgs/lucent 1 Internet Standards and the Internet Architecture Board Henning Schulzrinne Dept. of Computer Science Internet Real-Time Laboratory (IRT) Columbia University New York, New York schulzrinne@cs.columbia.edu Lucent Standards Symposium (Murray Hill) November 13, 2000

2 hgs/lucent 2 Overview review of IETF process growth of IETF is the IETF getting slower? who is contributing and participating? Internet Architecture Board recommendations

3 hgs/lucent 3 Realm of IETF layer 3 and above, plus IP-over-foo and layer 2.5 (PPP) network, transport (+ shims), application layers management for link layer not document/file/media formats like XML, HTML, JPEG, MPEG not APIs (exceptions: GSSAPI, LDAP, IPv6 socket extensions) no interfaces, but protocols not architectures, but modular components

6 hgs/lucent 6 IETF who s in charge usually, active participants not from standards departments, but from R&D participants are expected to speak for themselves, not company liaisons not that important working group chairs guide WG activities, prime candidates for IESG/AD IESG/ADs can initiate and delay, but rarely shape IAB can initiate, but doesn t influence details

7 hgs/lucent 7 IETF growth: RFC output Number of RFCs published IETF attendees per RFC Year

8 hgs/lucent 8 I-Ds vs. RFCs anybody can submit an I-D on just about any topic roughly, less than one in six I-Ds becomes an RFC usually, very little change in last revisions can start implementations

9 hgs/lucent 9 IETF growth: I-D output Number of RFCs published Number of IDs published Year

10 hgs/lucent 10 IETF growth: meeting attendance 2500 Attendess San Jose Oslo Minneapolis Adelaide 500 Amsterdam Stockholm IETF meeting

11 hgs/lucent 11 IETF is getting slower Delay from -00 to RFC (months) Year

12 hgs/lucent 12 Delays in the process months SIP RTP avg. 00 last call approved RFC

13 hgs/lucent 13 RFC size is not the culprit Average size of RFC Year

14 hgs/lucent 14 IETF activity I-Ds RFCs WG chairs IESG nomcom Cisco Lucent Microsoft Nortel Sun

15 hgs/lucent 15 Internet Architecture Board (IAB) IAB is a technical advisory group of ISOC/IETF, selected by NomCom IESG Selection: IAB appoints new IETF chair and other IESG candidates, from list by IETF NomCom. Architectural Oversight: oversight of architecture for protocols and procedures. Standards Process Oversight and Appeal: oversight of Internet Standards process; appeal board for complaints. RFC Series and IANA: editorial management and publication of RFCs; administration of Internet assigned numbers. External Liaison: representative of the interests of the Internet Society in liaison relationships. Advice to ISOC: advice and guidance to Internet Society for technical, architectural, procedural, and policy matters.

16 hgs/lucent 16 Aside: Nominations Committee (NomCom) nominates candidates for IAB and IESG 10 voting members + chair + liaisons to IAB/IESG + last year s chair voting members selected randomly from volunteers volunteers must have been at 2 out of 3 past IETF meetings

17 hgs/lucent 17 IAB members Harald Alvestrand Maxware Ran Atkinson Extreme Networks Rob Austein Fred Baker Cisco IETF chair Brian Carpenter ICAIR/IBM Steve Bellovin AT&T Liaison to the IESG Jon Crowcroft UCL Leslie Daigle ThinkingCat Steve Deering Cisco Tony Hain Microsoft Geoff Huston Telstra John Klensin AT&T IAB Chair Henning Schulzrinne Columbia U. Randy Bush PSG Liaison from the IESG Joyce K. Reynolds RFC editor Abel Weinrib Intel IAB Executive Director Erik Huizer SURFnet

18 hgs/lucent 18 IAB functions meets monthly by phone conference and at IETF meetings most of the detailed technical review done by IESG: issue last calls draft reviews and standards actions new working groups

19 hgs/lucent 19 Recent IAB discussions ICANN issues (IAB is member of PSO) I18N for DNS allow non-ascii characters QoS architecture unique root firewalls and NATs VoIP architecture document IETF process reform discussions workshops on wireless, routing workshops on middle boxes and I18N planned

20 hgs/lucent 20 Process problems to be addressed whole network envy of link layers (ATM, Bluetooth) rubber-stamping of closed organizations filibusters and other delays IESG overload most recent deployed protocols are proposed standards NNTP, PPP, RTP, SIP, RTSP,SNMPv2,FDDIMIB,SOCKS,IMAP,RSVP,...ordraftstandards: PPP (RFC 1548), HTTP/1.1, BGP4,...

21 hgs/lucent 21 Cultural problems IETF does components, not architectures does not mandate set of protocols to be used different: SoftSwitch consortium, 3GPP not too good at re-use (but then, ASN.1 wasn t exactly a success...)

22 hgs/lucent 22 Recommendations avoid time-wasting internal coordinated positions on protocols internal victors may still back the wrong horse funnel consortia work into IETF early don t expect rubber stamp avoid splitting of effort (ITU, 3GPP, Tiphon) authors have more influence in IETF speed up work by providing comments, holding chairs to schedule
