H. Newman (Caltech)30/09/2004, 14:00Track 7 - Wide Area Networkingoral presentationWide area networks of sufficient, and rapidly increasing end-to-end capability are vital for every phase of high energy physicists' work. Our bandwidth usage, and the typical capacity of the major national backbones and intercontinental links used by our field have progressed by a factor of more than 1000 over the past decade, and the outlook is for a similar increase over the next...Go to contribution page

G. Lo Re (INFN & CNAF Bologna)30/09/2004, 14:20Track 7 - Wide Area Networkingoral presentationNext generation high energy physics experiments planned at the CERN Large Hadron Collider is so demanding in terms of both computing power and mass storage that data and CPU's can not be concentrated in a single site and will be distributed on a computational Grid according to a "multi-tier". LHC experiments are made of several thousands of people from a few hundreds of institutes...Go to contribution page

Dr S. Ravot (Caltech)30/09/2004, 14:40Track 7 - Wide Area Networkingoral presentationIn this paper we describe the current state of the art in equipment, software and methods for transferring large scientific datasets at high speed around the globe. We first present a short introductory history of the use of networking in HEP, some details on the evolution, current status and plans for the Caltech/CERN/DataTAG transAtlantic link, and a description of the topology and...Go to contribution page

Dr J. Tanaka (ICEPP, UNIVERSITY OF TOKYO)30/09/2004, 15:00Track 7 - Wide Area Networkingoral presentationWe have measured the performance of data transfer between CERN and our laboratory, ICEPP, at the University of Tokyo in Japan. The ICEPP will be one of the so-called regional centers for handling the data from the ATLAS experiment which will start data taking in 2007. More than petabytes of data are expected to be generated from the experiment each year. It is therefore essential to...Go to contribution page

Dr Y. Kodama (NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY (AIST))30/09/2004, 15:20Track 7 - Wide Area Networkingoral presentationIt is important that the total bandwidth of the multiple streams should not exceed the network bandwidth in order to achieve a stable network flow with high performance in high bandwidth-delay product networks. Software control of bandwidth for each stream sometimes exceed the specified bandwidth. We proposed the hardware control technique for total bandwidth of multiple streams with...Go to contribution page

Mr M. Grigoriev (FERMILAB, USA)30/09/2004, 15:40Track 7 - Wide Area Networkingoral presentationLarge, distributed HEP collaborations, such as D0, CDF and US-CMS, depend on stable and robust network paths between major world research centers. The evolving emphasis on data and compute Grids increases the reliance on network performance. FermiLab's experimental groups and network support personnel identified a critical need for WAN monitoring to ensure the quality and efficient...Go to contribution page

E. Ronchieri (INFN CNAF)30/09/2004, 16:30Track 7 - Wide Area Networkingoral presentationThe problem of finding the best match between jobs and computing resources is critical for an efficient work load distribution in Grids. Very often jobs are preferably run on the Computing Elements (CEs) that can retrieve a copy of the input files from a local Storage Element (SE). This requires that multiple file copies are generated and managed by a data replication system. We...Go to contribution page

P. DeMar (FERMILAB)30/09/2004, 16:50Track 7 - Wide Area Networkingoral presentationAdvanced optical-based networks have the capacity and capability to meet the extremely large data movement requirements of particle physics collaborations. To date, research efforts in the advanced network area have been primarily been focused on provisioning, dynamically configuring, and monitoring the wide area optical network infrastructure itself. Application use of these...Go to contribution page

Mr G. Roediger (CORPORATE COMPUTER SERVICES INC. - FERMILAB)30/09/2004, 17:30Track 7 - Wide Area Networkingoral presentationA High Energy Physics experiment has between 200 and 1000 collaborating physicists from nations spanning the entire globe. Each collaborator brings a unique combination of interests, and each has to search through the same huge heap of messages, research results, and other communication to find what is useful. Too much scientific information is as useless as too little. It is time...Go to contribution page

Mr P. Galvez (CALTECH)30/09/2004, 17:50Track 7 - Wide Area Networkingoral presentationVRVS (Virtual Room Videoconferencing System) is a unique, globally scalable next-generation system for real-time collaboration by small workgroups, medium and large teams engaged in research, education and outreach. VRVS operates over an ensemble of national and international networks. Since it went into production service in early 1997, VRVS has become a standard part of the toolset used...Go to contribution page

Mrs L. Ma (INSTITUTE OF HIGH ENERGY PHYSICS)30/09/2004, 18:10Track 7 - Wide Area Networkingoral presentationNetwork security at IHEP is becoming one of the most important issues of computing environment. To protect its computing and network resources against attacks and viruses from outside of the institute, security measures to combat these are implemented. To enforce security policy the network infrastructure was re-configured to one intranet and two DMZ areas. New rules to control the...Go to contribution page
