The Internet Society•Founded in 1992 by Internet Pioneers• International non-profit organisation

•140 organisation members•80,000+ individual members•110 chapters worldwide•Regional Bureaus: Africa, Latin America & Caribbean, Asia Pacific, Europe, North America

•Vision•The Internet is for everyone.

•Mission•To promote the open development, evolution, and use of the Internet for the benefit of all people throughout the world.

2

Why Standards?

•Networks existed without the Internet

•Multiple proprietary networking protocols• IPX/SPX, AppleTalk, DECnet, etc

•Networks as islands• Interconnection the challenge

•Standards enable thousands of networks to interconnect seamlessly

3

Who needs standards?

•The Internet works…because people choose to make it work…and they collaborate to make it work

• Internet standards•Openly developed•No affiliation or membership required to participate in open, transparent, inclusive processes

•Openly available•No fees to access or apply the standards in applications and devices

•Voluntarily applied•No governing body to enforce compliance

4

Open standards for innovation and choiceThe Internet's open, neutral architecture has proven to be an enormous engine for market innovation, economic growth, social discourse, and the free flow of ideas. The remarkable success of the Internet can be traced to a few simple network principles – end-to-end design, layered architecture, and open standards – which together give consumers choice and control over their online activities.

- Vint Cerf, Internet Pioneer Statement to U.S. Senate Committee on Commerce, Science, and Transportation Hearing on “Network Neutrality”February 2006

The mission of the IETF is to make the Internet work better by producing high quality, relevant technical documents that influence the way people

design, use, and manage the Internet.

IETF standards are published as RFCs • Standards track • Best Current Practices (operational) • Informational and Experimental

RFC series also includes • IRTF (Internet Research Task Force) • IAB (Internet Architecture Board) • Independent contributions

Standards Track documents are maintained by the IETF • IESG approval: based on consensus

Internet Standards development process at the IETF • To host one of the IETF meetings in an African city in the next 5

years.

IETF CodeMatch

March 2015 Kathleen Moriarty Lisandro Granville

CodeMatch Overview● What is CodeMatch?

● Marketplace which brings together students, researchers, professors, open source development communities, vendors with proprietary implementations, and consumers of code bases

● Objectives ● Link existing implementations to standards ● Showcase opportunities to develop running code for

IETF protocols ● Provide clear benefits to each user type from

increased collaboration

For more information: https://codematch.ietf.org/

https://codematch.ietf.org/

IETF Hackathon ● What is IETF Hackathon?

● IETF Hackathons encourage developers to collaborate and develop utilities, ideas, sample code and solutions that show practical implementations of IETF standards.

● Objectives ● Bring developers and young people into IETF and get

them exposed to and interested in IETF ● Advance pace and relevance of IETF standards

activities

EncriptionWe are talking about more than encryption. Encryption is just a tool for enhancing privacy and trust

Encryption | 9 June 2016

• Leads to reassessment of the role of intelligence in the network and the role of the end-users.

Ubiquitous Encryption may have a profound effect

28

• Caching • DPI to filter web

content (malevolent and benevolent)

• Traffic management • Media optimization

Example: Filtering of Wikipedia Article

Example: f

dset

Example: f

provider


The realities….

“Everything is in the clear” approach is clearly unworkable

Encryption will reduce the number of parties that see traffic

But not eliminate them — content provider, browser vendor, CAs, proxy provider, corporate IT department, …

World still moves ahead on a voluntary basis on what technology is chosen and on what technology a particular party can adopt

Surveillance shifts, not eliminated

Useful technical things done in different ways, not eliminated Some potential bad outcomes to avoid —- MITMs, regulation limiting security, fragmentation, device control, …
