Networks, Grids and Service Oriented Architectures

CA*net 4 is NOT an optical switched network >CA*net 4 is made up of many parallel application empowered or customer empowered specific networks eg: – Computer back planes (Westgrid) – High energy physics network >It extends the Internet 2 architecture of GigaPOPs connecting a small number of R&E institutions to a much finer scale with many parallel “application empowered” Internet 2 like networks connecting individual researchers and/or applications – With added feature that the application or user can dynamically manage their own IP network topology – Application empowered networks peer with each other at GigaPOPs and at optical switches which provides for greater reliability >The CA*net 4 wavelengths and switches are partitioned such that application empowered networks can control their own partition and incorporate alarms, topology and discovery into their IP network – User controlled traffic engineering – New ITU draft standard – Y Layer 1 VPNs

Multi-physical channel TCP >Experiment this summer with low level trigger data from CERN – Inboud to Canada: 5 Mbytes per trigger – 500 triggers per second and increasing – Outboud: 1K per trigger – 100 triggers per second >Set up separate TCP/IP per physical channel >Each physical channel dedicated 1 GbE lightpath >Physical channels configured with UCLP >Can use out of the box TCP with no special AIMD – Far less susceptible to packet loss – only one channel affected >Already demonstrated manually at SC2003 – Achieved bi-directional bandwidth of 11 Gbps

MonFox TL1 Proxy >The missing element that makes things come true! TL1 LightPath Proxy CANARIE’s vision: UCLP (Users Control LightPath) End users’ dream: (my own fast & big bandwidth connection)

Motivations >How can you safety deploy any number of different UCLP software solutions (there are 4) and have your users manage lightpaths across your network, without affecting current operations?

i-Infrastructure >CANARIE’s proposed program for Canadian science and industry >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

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

Parallel Developments >NRC’s NMR portal - SpectroGrid – Single portal for monitoring and viewing data from NMR machines >NEESgrid – Linking shake tables, field instruments and databases >EU’s GridCC – Virtual Instrument Grid Service >Possible upcoming projects – Neptune, CVO, CLS
