WHREN-LILA Activities

The WHREN-LILA project, with support from ANSP and RNP, enabled the distributed Tier2 in Brazil, of the CMS LHC experiment, to participate in the Super Computing 2008 (SC08) Bandwidth Challenge event.  SPRACE, the Tier2 in Sao Paulo, and HEPGRID, the Tier2 in Rio de Janeiro, each were able to connect to the SC08 network at layer2 using Ethernet.  The capability to extend Brazil's Tier2s to SC08 was made possible through the use of the Cisco Research Wave (C-Wave).  Currently, SPRACE is connected to the ANSP network using a 1 GigE port, and HEPGRID, likewise connects to the RNP network using a 1 GigE port.  SPRACE achieved a maximum link utilization of 890 Mbps, and HEPGRID was very close to achieving a maximum link utilization of 600 Mbps, over a shared LILA East link.

Pacific Wave Activities

During the recent Supercomputing 2008 (SC08) conference held in Austin, Texas November 16-20, 2008 , Pacific Wave provided a 10 gigabit circuit from Los Angeles, CA to Austin, Texas using NLR resources. Pacific Wave participants used this connection to participate in bandwidth challenge activities and provide demonstrations of technology.

Pacific Wave SC08 participants included the following:

The University of Tokyo showcased two demonstrations: "Parallel TCP streams with stream harmonization" and "Single TCP stream to challenge 10GBASE-LANPHY max";

A JGN2Plus connection supported the National Center for Data Mining's (NCDM) demonstrations on storage services for astronomy, cyberdefense and bioinformatics;

NTT GEMNET and Osaka University's HDTV demonstration showcased NTT's i-Visto system including the interoperation between i-Visto and the University of Washington's iHD1500 system; in a separate project, a new 10-Gbps network interface card with high-accuracy traffic-measurement capabilities including precise latency measurement was demonstrated;

KISTI demonstrated both Global Visualcasting and the OptIPuter/OptIPortal projects.

The two Bandwidth Challenge Finalists were:

University of Illinois at Chicago's (UIC) Electronic Visualization Laboratory (EVL), along with partner Sharp Laboratories of America "Global Visualcasting - Collaborative Remote Visualization Over High Speed Networks". Steams of 4K and Full High-Definition (HD) video, audio and visualizations were sent to three booths on the SC08 show floor in Austin from two Midwestern universities, and several research institutes in Korea, Japan, Australia, Russia and the Czech Republic, to create a sustained global teleconference. The University of Queensland, Australia used an SX-Transport link sponsored by Southern Cross and Pacific Wave facilities sponsored by the NSF IRNC project Translight/Pacific Wave to reach the show floor. During the conference, this connection saw a maximum of 1.7 gigabits per second traversing the SX Transport to Pacific Wave, but was running at 1 gigabit per second most of the time; and

Building on seven years of record-breaking developments, an international team of physicists, computer scientists, and network engineers led by the California Institute of Technology, with partners from Michigan, Florida, Tennessee, Fermilab, Brookhaven, CERN, Brazil, Korea and Estonia joined forces to set new records for sustained data transfer among storage systems during the SuperComputing 2008 (SC08) conference/ The record-setting demonstration entitled "High Speed Data Gathering, Distribution and Analysis using Next Generation Networks" was made possible through the use of twelve 10 Gbps wide area network links to SC08 provided by SCinet, National LambdaRail (6), Internet2 (3), ESnet, Pacific Wave, and the Cisco Research Wave, with onward connections provided by CENIC in California, SURFNet (Netherlands) and Canarie (Canada) to Amsterdam, as well as CENIC, Atlantic Wave and Florida LambdaRail to Gainesville and Miami, US Net to Chicago and Sunnyvale, Gloriad to Daegu i
n Korea, GEANT to Estonia, and the WHREN link co-operated by FIU and the Brazilian RNP and ANSP networks to reach the Tier2 centers in Rio and Sao Paulo.

Jacqueline Brown and John Silvester attended the Internet2 Member meeting in New Orleans, LA October 13-16, 2008 where John gave a talk entiled "Translight/Pacific Wave". During SC08, Celeste Anderson gave a presentation entitled "Los Nettos and Translight/Pacific Wave". Both presentations are now available on the Pacific Wave website www.pacificwave.net.

RNP Activities

RNP lays the groundwork for Infrastructure Public Key for Education and Research

On November 13, at the headquarters of the Ministry of Science and Technology (MCT), a ceremony was performed to establish the pair of keys for the Infrastructure Public Key for Education and Research (ICPEDU), an experimental service National Network for Teaching and Research (RNP), responsible for Internet Brazilian academic. Among those attending the event were: the Minister of Science and Technology, Sergio Rezende, the director-president of the National Institute of Information Technology (ITI), Renato Martini, and the director general of the RNP, James Nelson.

ICPEDU's proposal is the establishment of an infrastructure to generate digital certificates and security keys initially turned to Federal Institutions of Higher Education (IFES) and Research Units (UPS). With the ICPEDU, organizations part of the infrastructure will issue digital certificates as they choose which act as electronic signatures personal and non-transferable, allowing its wide use.

A practical example of use of these licenses is in a university where teachers and students each have their own certificate. A teacher can send student grades over the Internet. As the value of the certificate has a signature recognized by the institution, the university can have the assurance that the sender was really teacher. And this applies not only to the launch of banknotes, but also the delivery of work and much of the administrative processes of the institution. This process will save time and paper as well as providing more security and more control of document delivery.

The ceremony on this day was a vital step for the ICPEDU, who has been in an experimental state since 2007, so that it can be put into operation in 2009. The establishment of this service was only possible thanks to studies of two Working Groups of RNP (GTs RNP), which created the management system of digital certificates ICPEDU (SCGI) and a hardware for the storage of private keys (Hardware Security Module -- HSM).
