Many Important physics results : One of the highlights is Observation of large CP-violation in B-system Announced at the international symposium on the Lepton-Photon Physics in Rome, Nearly at the same time as the announcement by its US competitor, BaBar Experiement at SLAC Belle Experiment High Energy Physics during 1995-present

15 CENTER FOR HIGH ENERGY PHYSICS 15 TEIN Bandwidth requirement –From CERN 100 MB/s experimental data trasfer –24 hrs/day, 10 million seconds/year operation –Data Size =1 PetaBytes/y –MC data production(2 PB/y) and transfer to Europe and USA –Therefore we need 2.4 Gbps 800 Mbps (Exp Data) 1600 Mbps (MC Data) Considering other traffic, we need 10 Gbps. Hyeonhai/APII 2.5 ~ 10 Gbps (KEK, Fermilab ) TEIN GEANT-Renater2- (2.5~10 Gbps)-KOREN (CERN) KOREN Topology Gbps 20 Gbps Bandwidth requirement Gbps Korea-Japan (alone) Bandwidth Requirement KEK Experiments – 130~370 Mbps by 2006 – 650 Mbps after 2006 Korea-Japan-USA Connection (additional) – Fermilab CDF Exp. (40~230 Mbps) – CMS Exp (800 Mbps) –Total bandwidth requirement: –1.2~1.6 Gbps Total of minimal 2.4 Gbps is required Considering other traffic, we need 10 Gbps

16 CENTER FOR HIGH ENERGY PHYSICS 16 Traffic/Data for HEP experiments carried out in Japan Belle Experiment –At present, data of 30 Tbytes/year are being collected: 0.3 TB/day It is approxmately 5~15 Mbytes/s, meaning 40 ~120 Mbps Production and share of Monte Carlo simulated data (~3 times of real data) among Korea-Japan collaborators (file transfer) Therefore, 120 Mbps~360 Mbps is needed (24 hrs/day operation, 25 millions seconds in total operation per year) –After 2006, we expect collecting data at 220GHz amounting 2 PB data/year Koreans expect processing 30% of data (600 TB/year) 4800 Tb/30 Ms = 160 Mbps Monte Carlo data production and share with Japan (approx 1.8 PB/year) 480 Mbps Therefore, we need 640 Mbps between Japan-Korea for this experiment K2K Experiment –Until 2001, we have approx. 830 GB of unprocessed data –Processed data size is 3.1 TB –Expect the same size of data in 2003 –Monte Carlo Simulation Data is about 1.6TB –We need 2~3 Mbps SuperKamiokande(Super-K) Experiment (Kamioka-near Toyama) –Collects approx. 27 Gbytes of data, needs 8*27 Gb/86.4 ks = 2.2 Mbps –About the same size of Monte Carlo data are produced –We need 5~6 Mbps

17 CENTER FOR HIGH ENERGY PHYSICS 17 Bandwidth Requirements Korea-Japan-USA Summary for Korea-Japan connection –130~370 Mbps by 2006 –650 Mbps after 2006 When Genkai is extended to USA via Korea-Japan – CDF Experiment at Fermilab Run IIa( ) and Run IIb(after 2004 ) – 500 Tbytes/year are produced (Run Iia), > 3 Pbytes (after 2004) Before 2004 : 10% processing (50 TBytes/year) : ~ 13 Mbps After 2004 : 10% processing (300 TBytes/year) : ~ 76 Mbps Monte Carlo Data Production and Transfer: twice the above Before 2004 : 40 Mbps After 2004 : 230 Mbps –Data Transfer for CMS (Europe) Monte Carlo Data Production and share with USA CMS Collaborators 15 years from 2003, we share 1 Petabytes/year = 800 Mbps is needed –Summary of Bandwidth requirement Year Between Korea-Japan Mbps Between Japan-USA Mbps (for Korean traffic)

18 CENTER FOR HIGH ENERGY PHYSICS 18 Suggestions In Summary Minimal bandwidth requirements for the HEP research is –2.5 Gbps over Korea-Japan-USA –2.5 Gbps over Korea-Europe Suggest that if we use the Busan-Kyushu line for Korea-USA APII, we need the network to be 2.5 Gbps initially and then 10 Gbps at least reflecting other usage in near future. Also we need TEIN to be 2.5 Gbps initially and then 10 Gbps as a separate network
