  1. Digital Divide • Santoro • UERJ -BRAZIL • Introduction • Topologies • Extracts from AMPATH Valdivia Group Report • Questionnaire / Responses • General Considerations; Type of Problems • Suggested Solutions A.Santoro

  2. I - Introduction The history of each network appear in the present situation. ( Distribution of Bandwidths ) WHY to investigate the Digital Divide? For High Energy Physics, If we want to get a Grid architecture to work in the LHC experiments, including the collaborators of the present experiments, we have to have a minimum of the compatibility of the links. We have used in this report (up to now) the Terena Compendium Information from Valdivia Group and responses from our own questionnaire. A.Santoro

  3. II - Topologies A.Santoro

  23. Extracts from AMPATH Valdivia Group Report We have a lot of information but not for Digital Divide conclusion. Bandwidth rates it is necessary to know. Perhaps the most important information for today is : Countries having groups working in HEP-Collaborations Brazil: Fermilab, CERN, … Argentina: Fermilab, CERN, … México : Fermilab, CERN… Colombia: Fermilab… Equator: Fermilab… Bolivia : Cosmic Rays (only?) Other countries: still not have good information. A.Santoro

  24. Questionnaire / Responses Table I – Respondents Remark: Respondents are Network Administrators and HEP physicists. A.Santoro

  25. Table II - Connection Status (1) Internal problems. Obsolete technology, router problems, networking equipment, intercampus connection (2) Regional and National problems. Last / first mile problem. Last 1000 miles problem. Network /POP Hierarchy connection / bandwidth problems (3) International connection / bandwidth A.Santoro

  26. Table III - Connection details A.Santoro

  27. Tabel IV - Other networking needs A.Santoro

  28. Table V - Most relevant networking related problems The most relevant Networking related problems are: Internal Networks, Last mile connections, Financial Support, and too low bandwith. A.Santoro

  29. Table VI - Presented ideas for prospective solutions Better funding, upgrades, are the main proposals A.Santoro

  30. Table VII - Present Computing Facilities Dedicated to HEP A-Mainframe, Clusters, LAN, Networked CPUS A.Santoro

  31. B-Firewall, WAN, Hops, Financial Support A.Santoro

  32. General Considerations How one’s network capabilities affect the ability to “Do Science”? What are the common problems? Type of Problems Long Mile Connection, Last Mile Connection, Security, .... Suggested Solutions To know better the problems like -Institutional Problems – Internal Networks, old equipments,... -Last mile connection: Institution to Network To discuss a possibility to present the problem to ONU and/or OEA or to a compatible organization and suggest solutions IF we want that GRID work beyond Europe, USA and some Region of Asia then we have to investigate at least the Institutions collaborating with HEP and try to get a minimum required for their needs.
