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

Gaming: Fast response, but equal delay
Best Effort Internet
Service awareness in the network can improve the QoE
