The State of the IETF Keeping one Internet Harald Alvestrand, IETF chair Antalya, May 13, 2001

The IETF in review What is the Internet? What is the IETF? What does the IETF work on? What challenges do we face?

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 Internet directions and concerns

The Internet today The optical internet backbone Gigabit to terabit links Access networks xDSL, cable modem, ISDN, asynchronous dial Campus Networks (LANs) UoSAT-12 Internet in Airlines

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

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

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 Therefore, our separate markets grow interdependently- Example: A better routing algorithm might make network computers a more acceptable product

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 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

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

IETF vision for the future Provider view Internet as interconnected competing service providers User view Internet as universal interconnect The harmony is not obvious to all

Threat to growth Balkanization: Names that can’t be used by all Formats that can’t be used by all Networks that can’t be used by all We need one Internet!

One Protocol: IPv4 and IPv6 IPv6 Internet Private Internet IPv4 Internet $

V6 and interworking V6 is deploying (at last) A plethora of interworking options A lack of solid experience with usage Some DNS details being worked on AAAA vs A6, bitstring labels vs nibbles Go Build Networks!

The Sub-IP Temporary Area 7 Working Groups Shares AD with other areas (Bradner, Wijnen) Structure how IP runs over lower layer media Includes IP-in-IP, IP-in-MPLS and so on Does NOT include MPLS-in-MPLS

One Routing Domain routes Probably greatest short term challenge Exponential growth Real requirements driving growth Rethink required Source: Geoff Huston, TELSTRA

One Domain Name System I18N challenges are more than technical Identifiers are not names Getting names into the DNS is the easy part Patents are a pain Bq—aervweor3dfae4rtobnlaruoo.com? Courtesy of i-dns.net

We Want One Internet Filled with opportunities Global communication enhances business, trade, research All opportunities come with challenges IPv6 for more addresses Internationalization for global reach Scaling routing to a new level Ours to be responsible with
