Description
The LHCOPN network, which links CERN to all the WLCG Tier 1s,
and the LHCONE network, which connects WLCG Tier1s and Tier2s, have
succesfully provided the necessary bandwidth for the distribution of the data
generated by the LHC experiments during first two runs of the LHC accel-
erator. We give here an overview of the most significant achievements and
the current state of the two networks. It also explains how the two networks
are evolving to support Run3 and how they are preparing to meet the high
demands foreseen for Run4, notably by adopting new transmission technolo-
gies to increase the available bandwidth, introducing new software tools to
improve the efficient utilization of all the links, new monitoring capabilities
to increase the understanding of the network traffic.
In addition, we describe how and why LHCONE has been used also by
other HEP collaborations, the risk associated with this policy and how they
can be mitigated
