Project Objectives

� To provide future networks with: � A design methodology that consider dynamic and

flexibility in networks to meet service demands� Technologies that promote flexible, agile, dynamic

and self-evolving networking

� A Network capable of coping with:

Flexible Network Enablers

� Identification of metrics� Trade off of socio-economic aspects

and underlying resources� Trading enablers and policies

� Autonomic algorithms for route/network selection (centralised and distributed)

� Virtualisation of network

� Virtualisation of network resources enablers

� Robustness and efficiency enablers� multipath routing and network

coding mechanisms in virtualised networks.

� Verification enablers for network configurations statically and dynamically

Expected Impacts

� Economic Significance � adapting to changing user needs and system requirements,

decrease OPEX and potentially also the required capital investment (CAPEX).

� more efficient utilization model � reducing the time-to-market of networks and services

� Social Benefits

www.mobilevce.com

© 2010 Mobile VCE

� Social Benefits� adapt solutions more efficiently to changing societal concerns,

as expressed, e.g., in regulation or changing user preferences. � accommodate changing societal requirements without re-

investing in new build-out.

� Environmental Benefits� operate networks more flexibly according to environmental

requirements. Allow for more energy-efficient resource allocation schemes.
