Network (R)Evolution – How?
Is
I it just
j t IPv7
IP 7 or IPv8
IP 8 … or creating
ti an alternative?
lt
ti ?
By adding and patching we run into the risk of
“obesity
obesity and a weak immune system”
system
Or should we even dare to think of tailor-made networks,
fit for the purpose and reliable?
Will migration work?
How can we solve this?

Network Virtualisation – Main Innovations
Network virtualisation as a meta
meta-architecture
architecture in a commercial setting
– Enable co-existence of diverse network architectures
– Enable deployment of innovative approaches
– Enable new business roles and players
• Allow split of infrastructure-/network-/service-providers
• Lower barriers of entry
• „Market place“ for shareable network resources
Provisioning and virtualisation management framework
– On-demand instantiation of virtual networks at large scale
Virtualisation of diverse resources in a common framework
– Routers, links, servers – can all be done today but need a unifying e2e
approach
– Extension on the virtualisation of the wireless infrastructure and spectrum
– Folding points providing interworking between virtual networks

What if we start to network the
information we are looking for?
Triggered by Van Jacobsen and
others a new view on interconnecting

that could change the way we engineer networks
fundamentally

How to transport?
Can
C we assume that
th t turning
t i wireless
i l
and
d optical
ti l media
di into
i t
copper will work forever?
And why is it efficient to do transport innovations only as
overlays?
What can be gained with a completely
fresh view on transport mechanisms?
The Generic Path is an answer to
these questions...

– a much richer class of data flows, beyond TCP, UDP
– state within the network, as necessary
y but no more than necessaryy
– common management interfaces, to set up and tear down flows and
to query their status
– explicit

identification,, notably
y to facilitate control of multi-flow
applications like videoconferencing
mechanisms for assured performance and efficient operation
– to exploit techniques like network coding and cooperative
transmission
– to choose the "best" paths for the considered transport
– to ensure resource sharing is "fair"
fair and meets application
requirements
– to manage the mobility of users, networks and information

t h i l innovation
i
ti
approaches in all areas of future networking
They all start from a clean
clean-slate
slate perspective,
perspective defining
radically new solutions for the Network of the Future
After 11 month work first results look promising
Now the hard work of refining and integrating starts
towards a new
Network of the Future
