Czech Republic joined the new global LHCONE network

Prague, 18 July 2013. The CESNET Association has connected the computing centre of the Institute of Physics of the Academy of Sciences of the Czech Republic to the new global network, LHC Open Network Environment (LHCONE). The LHCONE interconnects important computing centres within the Worldwide LHC Computing Grid (WLCG),  used by the Large Hadron Collider (LHC) at the CERN laboratory in Geneva.

Czech research teams at Universities and Institutes of the Academy of Sciences participate in the experiments at the LHC. Last year, for example, Czech scientists were involved in the discovery of the Higgs boson. The Czech teams performing research in the field of particle physics use a common computing centre in the Institute of Physics AS CR. It represents one of more than a hundred distributed computing centres, which are able to automatically cooperate within the WLCG grid environment.

Until recently, most of the centres had been interconnected via shared Internet lines, or by means of a relatively small number of lines dedicated only for the WLCG. The immensely growing data volumes (hundreds of petabytes) and limited number of its copies required to find a new solution to centres interconnections. The new global network, LHCONE, has been therefore developed to interconnect important computing centres within the WLCG. It is a virtual private network created at L3 layer (L3VPN), using high-speed dedicated lines and traffic routing based on the Border Gateway Protocol (BGP). The aim is to separate massive WLCG grid operations from the public traffic, as well as to ensure a needed capacity and reliability for data transfer among the centres (more information is available at

The CESNET Association has developed the local infrastructure, and connected the computing centre of the Institute of Physics of AS CR from 28 June 2013. The connection to the LHCONE network is realized via the GÉANT network equipment installed at the CESNET site. The Institute of Physics–CESNET connection is based on the new DWDM 10G channel over the existing pair of optical fibres. Very soon after the connection establishment, the traffic reached peak results  up to 4 Gb/s.

The CESNET Association was founded by Czech universities and the Academy of Sciences of the Czech Republic in 1996. It is engaged in research and development in information and communication technologies and builds and develops the CESNET national e-infrastructure for research and education. With its research activities and accomplishments, CESNET represents the Czech Republic in international projects, most notably the pan-European GÉANT network building project and grid projects (, and participates actively in their implementation.
