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

2. 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?

3. 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

4. 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

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

6. Traffic Projections for Voice and Data Circuit Switched Voice
Growth of IP Traffic
Information search/access
Subscription services/“Push”
Conferencing/ multimedia
Video/imaging
Rel. Bit

8. 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!

9. 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?

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

11. 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!

12. 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

13. 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

14. One Routing Domain 100.000 routes
Probably greatest short term challenge
Exponential growth
Real requirements driving growth
Rethink required
Source: Geoff Huston, TELSTRA

15. 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

16. 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
