• Application Layer:
Applications use IP for
connectivity
• The Network Access Layer:
Components in the Network
Access Layer deliver IP
connectivity
• The IP Layer: provides a
coherent mapping between
the layers
• (IP=Internet Protocol)

Application Layer
• Applications are what the
users care about
• Most people conceive the
utility of the various
applications as the Internet
• E-mail and WWW are just
two applications, albeit
successful ones
• Business, voice and face
communication,
entertainment such as
videos and games

Network Layer
• The layer that provides the
IP to the
customers
• The Internet is made up out
of many independently
operated networks that all
provide some level of
network access
• The network exchange IP
packets between each other

1. Cooperation
Respectful cooperation between standards organizations, whereby each respects the autonomy, integrity, processes,
and intellectual property rules of the others.
2. Adherence to Principles
Adherence to the five fundamental principles of standards development:
• Due process. Decisions are made with equity and fairness among participants. No one party dominates or guides
standards development. Standards processes are transparent and opportunities exist to appeal decisions.
Processes for periodic standards review and updating are well defined.
• Broad consensus. Processes allow for all views to be considered and addressed, such that agreement can be
found across a range of interests.
• Transparency. Standards organizations provide advance public notice of proposed standards development
activities, the scope of work to be undertaken, and conditions for participation. Easily accessible records of
decisions and the materials used in reaching those decisions are provided. Public comment periods are provided
before final standards approval and adoption.
• Balance. Standards activities are not exclusively dominated by any particular person, company or interest group.
• Openness. Standards processes are open to all interested and informed parties.
3. Collective Empowerment
Commitment by affirming standards organizations and their participants to collective empowerment by striving for
standards that:
• are chosen and defined based on technical merit, as judged by the contributed expertise of each participant;
• provide global interoperability, scalability, stability, and resiliency;
• enable global competition;
• serve as building blocks for further innovation; and
• contribute to the creation of global communities, benefiting humanity.
4. Availability
Standards specifications are made accessible to all for implementation and deployment. Affirming standards
organizations have defined procedures to develop specifications that can be implemented under fair terms. Given
market diversity, fair terms may vary from royalty-free to fair, reasonable, and non-discriminatory terms (FRAND).
5. Voluntary Adoption
Standards are voluntarily adopted and success is determined by the market.

The Internet Engineering Task Force is
a loosely self-organized group of people
who contribute to the engineering and
evolution of Internet technologies.
It is the principal body engaged in the
development of new Internet standard
specifications.
RFC4677

17.
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.

Statistics, Web Traffic
• HTTPS increased 4% to 17% from 2008 to 2014, for all
web traffic (Source: IIJ)

29.
Pain Points and Hot Debates
• There is no single reason behind the increasing use of
encryption, but the change has a real impact on the world
• Operator business models, technical solutions for various
things, censorship will be harder (both good and bad
kind), …
• All this will cause friction
• Motives of players are not fully aligned

30.
Reality Check
• “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, …
