During 2019 the configuration will change and there will be provided 2x100 Gb/s links to the two CERN POP granting a better resiliency and giving potentially 200 Gbpss full speed with CERN and the Tier-1s.

 The latency introduced by each CX1200 is of $\sim 5 \mu$s and the total RTT (Round Trip Time) between servers at CNAF and servers at CINECA is of 0,48 ms comparable to what we observe on the LAN (0,28 ms).
 
-All worker nodes on the network segment at CINECA have IP addresses of the INFN Tier-1 network and are used as they were installed at the Tier-1 facility (see fig.~\ref{cineca-schema}). The data access bandwidth is 400 Gbps but can scale up to 1,2 Tbps.

 This DCI interconnection has been implemented rapidly and as a proof of concept (this is the first time this technology has been used in Italy), now it is in production and as it is becoming a stable and relevant asset for CNAF (fig.~\ref{cineca-traffic}), it is in our plan to have a second optical fiber (between CNAF and CINECA) for resiliency reasons.
