The Future Network as we know it

Flexible and participatory – user and provider are dynamically attached roles Information centric rather than bit centric at the network level Security that nevertheless keeps the generativity1 of the network intact Low cost to access, deploy and operate ...

The Virtual e2e Network

• Deals with e2e resource

virtualisation of networking resources

• Includes wireless

virtualisation

• Opens the possibility for

more radical innovation in the network

• Enables migration from

current Internet

A new transport paradigm: the generic path

• Path generalisations in a functional architecture: How to

– Organize cooperation between nodes in a path

• Understand their existence, and signaling between nodes

– Structure cross-layer information

• Find out lower topologies and their capabilities

– Control underlay topologies

• “Multi-layer routing”
• Mobility by generic path
• Evaluation in proof-of-concept testbeds

split/ balance merge/ network code decode join code cooperatively Generic path 1 Generic path 2

Summary

Inherent integration of self-management Increasing the amount of network features reliably available to end-user applications

– Like mobility, QoS, security but also scalability, deployability

Driving innovation and new business opportunities into the network layer Defining a systems approach to the Future Internet Drive the work from the mobile and wireless perspective We are open and interested in collaboration with related international initiatives
