4Role
- Historical developer of Internet-related
protocols - http//www.ietf.org
- Consortium of individuals from
- Research, Education, Network operators, and
Internet vendors
5Organization
- Internet Society (ISOC) Legal entity, funding
insurance - Internet Architecture Board (IAB) Architecture
overview, Process appeals - Internet Engineering Steering Group (IESG)
Process Management - Working Groups (over 100 in 8 areas)
6Internet Architecture Board (IAB)
- Mission
- Oversight of IETF, IRTF, IANA, liaisons
- Think tank for future Internet activities
- Recent activities
- Really worried right now about
- Integrity of the infrastructure
- Intrusion of middle-boxes
- Impact of unbridled creativity
- Wireless communications
7Internet Engineering Steering Group (IESG)
- Mission
- Assure openness and adherence to process
- Working group chartering and management
- Quality assurance on specifications
- Activities and trends
- Making sure mobile networks are part of the
Internet - Trying to grow the network (IPv6, routing)
8Membership
- IETF members are individuals
- As opposed to nations or companies
- Communications tend to be among individuals
- As opposed to working groups, boards, etc.
- Have trouble understanding liaison
9Fundamental working principle
We reject kings, presidents, and voting. We
believe in rough consensus and running code.
Dr. David C. Clark, Massachusetts Institute of
Technology

13Working groups in eight areas
- Internet
- Routing
- Transport
- Applications
- Security
- Operations and management
- General
- (Sub-IP)
14Working group summary
- We have more than 100 working groups
- Not all currently active
- Maintain the IPv4 Internet
- Enable the IPv6 Internet
- Create the mobile Internet
- Make all the Internet useful and secure
15Development process
- Bottom-up
- Working Group charters developed to support work
people want to do - Development process
- Working groups develop to consensus
- IESG reviews
- RFC editor publishes
- Specified in RFC 2026
16Work model
- Primary work is conducted continuously on mail
lists - 3 face-to-face meetings per year
- Used for issues that are not resolved via email
- 7-10 parallel meetings in 1 to 2 ½ hour segments
- Mon-Thurs 9am to 10pm
- Orientation session Sun 12-4

18Two types of documents
- Internet drafts
- RFC - request for comments
19Internet drafts
- Most analogous to ITU contributions and
working papers - Not necessarily work items
- Half of all Internet drafts are simply documents
people have chosen to post - Nine out of ten I-Ds do NOT result in RFCs
- Types of drafts
- Working group documents
- Submissions to working groups
- Individual submissions
- Expire in 6 months
20RFCs
- Historical archive
- Many kinds of documents
- Informational
- Historical
- Experimental
- Standards
- Standards
- Proposed
- Draft
- Full
- Best current practice

22Fundamental 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 - Growing the Internet is good for all of us
- A larger Internet creates larger markets.
- Larger markets create cheaper products.
- Cheaper products create more end-user value.
23How IETF sees work divided
W3C
HTML
Telephony
Voice/ Video Data
HTTP
Signaling
Mail
SNMP
UDP
RTP
TCP
Internet Protocol
IEEE
ATM
Frame Relay
PPP
Ethernet
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
24IETF infrastructure protocols
- Some link layer
- PPP
- Network layer
- IPv4, IPv6
- Routing protocols
- Transport layer
- TCP, UDP, RTP
- Security services
- Transport layer security, IPSEC, ISAKMP
- Telephony signaling
- Signaling transport
- Quality support
- Differentiated services
- Integrated services
25IETF infrastructure applications
- SNMP management
- SMTP mail
- DNS name services
- LDAP directory services
- SSH virtual terminal protocol
- FTP file transfer
- HTTP web transfer
- And more...
