\section{\label{introduction:motivation}Motivation}
2019-08-08 12:08:07 +00:00
The Internet has almost completely run out of public IPv4 space. The
2019-08-08 12:45:16 +00:00
5 Regional Internet Registries (RIRs) report IPv4 exhaustion world wide
2019-08-08 12:08:07 +00:00
(\cite{ripe_exhaustion},
\cite{apnic_exhaustion},
2019-08-08 12:45:16 +00:00
\cite{lacnic:_ipv4_deplet_phases},
\cite{afrinic:_afrin_ipv4_exhaus},
\cite{arin:_ipv4_addres_option}) and LACNIC project complete
exhaustion for 2020 (see figure \ref{fig:lacnicexhaust}).

On the other hand IPv6 adoption grows significantly, with at least
three contries (India, US, Belgium) surpassing 50\% adoption
(\cite{akamai:_ipv6_adopt_visual},
\cite{vyncke:_ipv6_deploy_aggreg_status}).
\cite{cisco:_ipv6}). Traffic from Google users reaches almost 30\% as
of 2019-08-08 (\cite{google:_ipv6_googl}).

Make it easier
take away burden
In theory line speed - what is reality?
The motivation to write this thesis was...
2019-08-08 12:08:07 +00:00
IPv6 P4
Introduce the related research field/the project.
\section{\label{introduction:taskdescription}The Task}
2019-07-29 17:13:47 +00:00
P4 environment
a lot of potential
Programming language in the network
Not only faster, but also more convienient.
**** High speed NAT64 with P4
Currently there are two main open source NAT64 solution available:
tayga and jool. The former is a single threaded, cpu bound user
space solution, the latter a custom Linux kernel module.
This thesis challenges this status quo by developing a P4 based
solution supporting all features of jool/tayga and comparing the
performance, security and adaptivity of the solutions.
- Milestone 1: Stateless NAT64/NAT46 translations in P4
- Milestone 2: Stateful (dynamic) NAT64/NAT46 translations
- Milestone 3: Hardware adaption
Describe your task.

\section{\label{chapter2:linespeed}Line Speed NAT64}
NAT64 in software is CPU bound. Hardware can potentially do this at
line speed.
\section{\label{chapter2:transitition}Simplify IPv6 deployments}
Currently network operators have to focus on two network stacks when
designing networks: IPv6 and IPv4. As To simplify network setups
