9. ECOC 2007 9 www.ist-muse.eu Why to migrate intelligence in the access ? Quality (QoS): first fully trusted point close to the user – only point with complete view of all services per user Security: ingress/egress point to network Robustness: smaller number of users impacted in case of failure Scalablility: feasible data rates for DPI and processing
