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

Network Virtualisation – Main InnovationsNetwork Virtualisation – Main Innovations
Network virtualisation as a meta architecture in a commercial settingNetwork virtualisation as a meta-architecture in a commercial setting– Enable co-existence of diverse network architectures– Enable deployment of innovative approaches– Enable new business roles and playersEnable 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
approachapproach– Extension on the virtualisation of the wireless infrastructure and spectrum– Folding points providing interworking between virtual networks

But how to design a network architecture?
B i d t hi i ti t l f t tBy reusing and patching existing protocols we forgot todevelop tools for clean slate design esp. for the moredetailed network architecture specificationsCan such a design toolkit and process be easily developedand used?Where can we find reusable components other than protocolWhere can we find reusable components other than protocolspecs and implementations?How can we ensure interoperability?p y
