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


Relations among standards bodies


Who’s who in the IETF
Who does what and why
Internet directions and concerns
The Internet today

UoSAT-12
The optical internet backbone
Gigabit
to terabit links
Campus
Networks
(LANs)
Internet
in Airlines

Access networks
xDSL,
cable modem, ISDN, asynchronous dial
UNIVERSITY
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
W3C
IEEE
HTML
Voice/ Video
Data
HTTP SNMP
Mail
UDP
RTP
TCP
Internet Protocol
Ethernet ATM Frame Relay
PPP
A variety of physical layers and interfaces
Telephony
Signaling
MPLS
Cellular Radio
ETSI
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
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


User view


Internet as interconnected competing service
providers
Internet as universal interconnect
The harmony is not obvious to all
Growth of IP Traffic
Email
 Information
search/access
 Subscription
services/“Push”
 Conferencing/
multimedia
 Video/imaging

“From 2000 on, 80% of Service
Provider Profits Will Be Derived
from IP-Based Services.”

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!

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

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

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

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