  1. Networks, Grids and Service Oriented Architectures Bill.st.Arnaud@canarie.ca eInfrastructures Workshop

  2. The first Grid • Original Internet - NSFnet was intended to connect 6 supercomputer sites • But the network evolved into something completely different and more powerful than its original application to connect 6 supercomputer • Grid technology may be going through the same evolution • Its real power and application may go way behind connecting clusters and HPC sites

  3. Taiwan Ireland Taiwan Ireland Taiwan control switch directly using UCLP software User controlled topology Seattle NYC CA*net 4 GigaPOP STAR LIGHT

  4. CA*net 4 Update • World’s First customer controlled and managed network • Taiwan and Ireland first to provide in the world to provide direct user controlled layer 1 connectivity between Asia and Europe • Uses Grid technology – Globus Toolkit 3 • Korea about to sign – many others in negotiation

  5. UCLP Objectives • No central management • Uses state-full web services with SOA using Globus Toolkit 3.0 • Partitions optical switches into domains that can be managed and controlled by end users • Create discipline or application specific re-configurable IP networks to support grids

  6. Applications • Distributed back planes between HPC Grid centers • Westgrid 1 GbE moving to 10 GbE • SHARCnet 10 GbE • Distributed Single Mount file systems – Yotta, Yotta - SGI • Needs very consistent performance and throughput to truly act as a back plane • Frequent topology changes to meet needs of specific applications • Canada ATLAS – 980 Gbytes FCAL data once a month from CERN to Carleton U, UoAlberta, UoArizona, etc • Will significantly increase to Terabytes when production runs start • Would take over 80 days on IP R&E network

  7. Applications- 2 • CERN Low level trigger data to UoAlberta with GARDEN • Initially streaming data rates 1 Gbps moving to 10Gbps later in the year • Canadian virtual observatory • .5 Tbyte per day to UoToronto and UoHawaii • 250 Mbps continuous streaming from CCD devices • Neptune – Canada (and US?) under sea laboratory – multiple HDTV cameras and sensors on sea floor • Canada Light Source Synchrotron – remote streaming of data acquisition to UoAlberta • 2 to 5 Gbps continuously • Canadian remote Nano and micro electronics laboratories • Canadian military instruction to Czech republic

  8. i-Infrastructure • CANARIE’s proposed program for Canadian science and industry • The computer is no longer the network • Everything is the network • To adapt service oriented architecture (SOA) using state-full web services to integrate sensors and instruments into the network • Building and extending upon our original work in UCLP • Major applications after science are process control industry and military applications

  11. User perspective WS* CANARIE UCLP WS AAA process WS HPC Process WS** WS** WS* New Web service WS* Lightpath WS** New development WS* ONS15454 NLR or CA*net 4 USER with WSFL binding software WS** Log Archive Process 2 DMAS WS** Log Archive Process 1 WS* LAN UDDI or WSIL service registry Science Pod WS* LAN Sensor/Instrument WS** User defined WSFL bindings

  12. Features • All hardware (sensors -wireless and wired), software processes (Data processing and HPC) and network elements exposed as state-full web services • Hardware, software and network web services linked together by science user with WSFL user defined late state binding • Some web services may be expressed as abstractions of groupings of other web services • Hence all “science” processes use network data recursive architectures • Re use and replication of same modules for software, hardware and network for each science project
