The State of the IETF Keeping one Internet Harald Alvestrand, IETF chair Stockholm, June 5, 2001

I assume you know.... What is the Internet? What is the IETF? But want to know more about What does the IETF work on? What challenges do we face?

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

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

Threat to growth Balkanization: We need one Internet! 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!

Attack of the Walled Gardens AOL is a success Manage the user experience Builds upon the open Internet I-Mode is a success Extend the Internet experience in a particular way (partially with open protocols) RealNames is a success Localize the experience of ”name” Create a privately owned world-wide experience What does this mean to openness?

One Protocol: IPv4 and IPv6 $ Private Internet IPv6 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!

One spaghetti: Layer 2 1/2 MPLS, L2TP, ATM, All-over-All Sub-IP Temporary Area TE-WG PPVPN Others CCAMP Control Measure MPLS IPO ATM FR Others

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 100.000 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 strange characters in 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 is a fact Where communication exists, trade, economic growth and friendship is facilitated to the benefit of all All opportunities come with challenges IPv6 for more addresses Internationalization for global reach Scaling routing to a new level Ours to be responsible with
