Internet Engineering Task Force

“We make the net work” The mission of the IETF is to produce high

quality, relevant technical and engineering documents that influence the way people design, use, and manage the Internet in such a way as to make the Internet work better. These documents include protocol standards, best current practices, and informational documents of various kinds. [RFC 3935]

IETF Open Standards

While the mission of the IETF is to make the Internet work better, no one is “in charge” of the Internet. Instead, many people cooperate to make it work. Each person brings a unique perspective of the Internet, and this diversity sometimes makes it difficult to reach consensus. Yet, when consensus is achieved, the outcome is better, clearer, and more strongly supported than the initial position of any participant.

Successful protocols

Consider the following successful protocols:Inter-domain: IPv4, TCP, UDP, HTTP, SMTP, DNS, …Intra-domain: ARP, PPP, DHCP, OSPF, …

Successful: a protocol that is used in the way it was originally envisioned

Wildly Successful: a successful protocol that is deployed on a scale much greater than originally envisioned or used in ways beyond its original design

Page 5: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

Potential success factors

1. Meets a real need 2. Incremental deployment 3. Open code availability 4. Freedom from usage restrictions 5. Open specification availability 6. Open development and maintenance processes 7. Good technical design

Additional “wild success” factors: 8. Extensible 9. No hard scalability limitations10. Security threats sufficiently mitigated

IETF and Existing Protocols

Many successful IETF protocols have origins outside the IETF Technical quality not a primary factor in success

IETF had a role in improving many of these protocols, often after success of version 1

Much easier when version 1 included a mechanism for extensibility At least a protocol version number

Page 8: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

Ethos of the IETF IETF uses an open standards process

All interested people are invited to participate Even if unable to attend the face-to-face

meetings, join mail list discussions All documents are online, available to everyone

One Internet Open standards for a global Internet Maximum interoperability and scalability Avoid specialized protocols in different places Contributions are judged on merits:

rough consensus and running code

IETF takes on work when …

The problem needs to be solved The scope is well defined and understood Agreement that the specific deliverables Reasonable probability of timely completion People willing to do the work

Page 10: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

IETF is right place when … The problem fits one of the IETF Areas

Applications Internet Operations and Management Real-time Applications and Infrastructure Routing Security Transport

Working to get better at problems that span Areas Working on problems that span Standards

Development Organizations (SDOs) take significantly more effort to be successful

Page 11: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

IETF is successful when …

Participants care about solving the problem Participants represent all stakeholders

Successful Internet protocols have come from top-down and bottom-up approaches Bottom-up is more common today Most things are incremental improvements

Internet challenges Different technologies are pulling the Internet in

many different directions Power Bandwidth Mobility New applications Smart objects Infrastructure

Page 13: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

Power

Routers Consume lots of power and generate lots of heat Demands for even greater throughput

Small and Mobile Devices Act as always connected Many very small devices are servers Demands for longer battery life

Page 14: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

Bandwidth

Big pipes Greater bandwidth than ever before, and not just

between large data centers

Availability Competing technologies benefit consumers About one-third of the world's population has access

to the Internet, and it is growing steadily Must transition to IPv6 to scale to the whole world

Page 15: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

Mobility

Mobile Devices More and more capabilities: voice, video, email,

instant messaging, web browsing, geo-location

Mobile Networks Ships, trains, planes, and soon automobiles

Critical system using Internet protocols Connect passenger’s mobile and portable

devices

Page 16: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

New ApplicationsMany new applications Voice, video, and entertainment

Soon all integrated in the web browser Social networking Peer-to-peer (p2p) Presence and geo-location Synchronization among devices

Changing perception of the Internet Critical Demand for privacy and security

Page 17: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

Smart ObjectsEmerging uses Smart Grid Sensor networks and medical monitors

Many, many, many tiny Internet servers Huge number of addresses – requires IPv6 Large sleep cycles to reduce power needs Special security requirements

Requires small code footprint Authentication for firmware updates

Routing over intermittent links

Page 18: Russ Housley IETF Chair LACNOG 4 October 2011 Successful Internet Protocol Development

InfrastructureIPv4 Address Exhaustion Feb. 2010: IANA unused IPv4 address pool empty IPv6 offers much greater address space

IPv4 to IPv6 transition mechanisms available

Infrastructure Security DNS Security: authentication and integrity

DANE WG is expanding to include certificates Routing Security

RPKI provides authorization for IP address blocks Authentication mechanisms under development

Internet Challenge Summary

Different technologies are pulling the Internet in many different directions:

More demanding applications transferring much more data from many more locations to many more locations being used by many more users on vastly more devices

Your experience is needed to meet these challenges.
