20. 20 Future – has already started Put more bandwidth Consolidate services through a well designed data center Consolidate application servers, Web servers, communication equipment, security systems, system administrators, support personnel, and anything or anybody else that provides data services ( Cloud services and cloud computing) Put in place adequate mechanisms to understand current and future community needs. Users may know their current needs but usually do not have any idea about their future needs. Interconnect RNU to other NRENs (Eumedconnect3, Géant, Eduroam, ASREN, …)

21. 21 Future… Should organize and manage the network Data Center effectively so that QoS is acceptable, downtime is minimized, troubleshooting is easier, and the room's infrastructure is efficiently used Keeping data on the number of users, connections, etc., is no longer sufficient, we must maintain  QoS about the network  QoE metrics for the provided services Can we?
