networks across wide areas, and complemented with other Web Services based resources allows
the creation of discipline or application-specific distributed IT solutions.
As well certain distributed research organizations, like the Environment Canada labs, are using
UCLP to build a private, long lived internal network, also referred to as an Articulated Private
Network. Through the UCLP tool, a network engineer at Environment Canada can change the
topology, interconnection, and increase or decrease bandwidth along certain paths, as desired,
without ever having to signal or get permission from CANARIE, within the confines of the set of
resources over which they have control.
The demand for dedicated lightpaths and/or APNs has exceeded expectations. The lightpaths and
APNs are used in a variety of applications such as distributed backbones for grids, dedicated APN
for the high energy physics community, numerous international collaborations, Multi-channel
High Definition TV, remote access, control and data distribution of large science instrumentation.
In 2007 Inocybe Technology Inc. in Montréal, with research partners Communication Research
Centre Canada (CRC) and i2CAT in Spain, has taken one of the UCLP implementations to
commercialization. The Inocybe Argia is the name of the commercial product. The product
maintains the same design principles of the UCLPv2. The product information can be found
http://www.inocybe.ca/. CANARIE has obtained the commercial license of the product and used
the Argia tool for a number of demos. Eventually the Argia tool will be used as the end users tool.
High Energy Physics:
TRIUMF has built a Tier-1 (T1) Computing Centre for the ATLAS experiment in Canada. The
TRIUMF Centre will be linked in the LHC Computing Grid (LCG) and provide an interface to a
grid
of
computing
resources
at
universities
across
Canada.
In July 2005 CANARIE signed a Memorandum of Understanding (MOU) with HEPnet/Canada,
ATLAS Canada and TRIUMF to provide the high energy physics community with a dedicated 10
Gbps APN across Canada and initial 5 Gbps lightpath to the CERN Tier-0 (T0) Centre. This
lightpath became active in December 2006.
The TRIUMF T1 to CERN T0 circuit, depicted in Figure 37, runs over the CANARIE
infrastructure until it disembarks North America in New York City. Each T1 site must use a small
or series of small publicly routable Classless Inter-Domain Routing (CIDR) blocks as only traffic
from theo the Large Hadron Collider Private Optical Network (LHCOPN) address space is
allowed to flow over the network. Exchange of routing information is performed using Border
Gateway Protocol (BGP) at the T1 and T0 institutions. The 5 Gbps lightpath, terminated on
10GbE LANPHY interfaces in both ends, transits Canada west to east. First, the lightpath is
traveling over BCNet network from TRIUMF to the CANARIE PoP in UBC, and continues along
CANARIEs network, then debarks North America at the MANLAN transit exchange in New
York City. The lightpath enters Europe on SURFnet in Amsterdam and then transits Geant2
network to CERN. The TRIUMF T1 will hold 4.3% of the ATLAS data, which is typically half
the size of other Tier-1. Hence a 5 Gbps link is expected to be sufficient for the first few years of
LHC operation. However should the demand increase beyond 5Gbps, the lightpath capacity can
be increased in an increment of 155Mbps up to the full 10 Gbps.
