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.1312 - 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!

End users’
dream:
CANARIE’s
vision:
UCLP (Users
Control
LightPath)
(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
