GOALS AND OBJECTIVES
Rapid data exchange between the JINR IT laboratory and the global infrastructure of the Worldwide LHC Computing Grid (WLCG), which unites 140 computing centers in 34 countries.
To create a new, high-speed scalable communication channel.
- The following equipment was used at network nodes:
- A JINR Dubna terminal node - Nortel Optical Multiservice Edge (OME) 6500 Terminal, line equipment - Nortel Common Photonic Layer (CPL) amplifier and multiplexer;
- A Radishchevo amplifying node - linear equipment - Nortel Common Photonic Layer (CPL) amplifiers;
- A RosNIIROS M9 end node - Nortel Optical Multiservice Edge (OME) 6500 Terminal, line equipment - Nortel Common Photonic Layer (CPL) amplifier and multiplexer.
Client requirements for the Large Hadron Collider project communication channel were extremely sophisticated: there had to be uninterrupted 24/7 operation which would withstand of any load during times of most intensive measurement.
Jet Infosystems specialists examined, analysed and selected network equipment, and managed the operational launch. The new JINR Dubna - RosNIIROS M9 communication channel created by Jet Infosystems engineers is a DWDM backbone network with a superimposed IP packet backbone. The full length of the line exceeds 200 km and consists of three nodes: JINR Dubna, Radishchevo and RosNIIROS M9.
The backbone channel ensures transmission of two 10 Gbps Ethernet signals. Channel equipment allows for the combination of up to 88 signals with load-carrying capacity of 10, 40 and 100 Gbps. The number of signals transmitted between the nodes can be increased by simply increasing configurations at the end nodes.
