Our center became the 5th center in the entire WLCG (out of more than a hundred participating centers) where we have implemented central monitoring of network traffic. This is important for the planning and running the Network Challenge 2024 as well as for standard operations. Compared to CERN, our traffic is small, but it still reaches 100 Gbps at peak times. On the graph for the last eight hours, the maximum average transfer in a ten-minute interval is 50 Mbps (the graph uses units of MBytes/sec, it is necessary to multiply by 8 for Mbps).
