Update on CA*net 4 Network
[email protected]
CA*net 4 Update
> Network is 3 x 10Gbps wavelengths from different suppliers
– Cisco and Nortel Optical/Sonet/SDH cross connects
– Cost of wavelengths dropping dramatically
> 3rd wavelength operational in June
– Primary purpose to support international layer 1 (and layer 3) transit
> Most institutions in Canada connected with metro dark fiber
> Long haul dark fiber with DWDM in ORANs ( i.e. NRENs)
– 3700 km in Ontario
– 2500 km in Quebec
– 500 km in British Columbia
> Support for e2e lightpaths for high end applications to most
institutions bypassing campus router-firewall
– E.g. 10GbE CWDM to TRIUMF on University of British Columbia campus
> Active discussion about terminating CA*net 4 IP network services
– Encourage ORANs to directly peer with each other for exchange of IP traffic
– CA*net 4 may maintain routers for international peering
UCLP
> Uses grid technology to partition and manage
CA*net 4 optical switches
– Use Globus Toolkit 3.0
> Allows users to integrate partitions of various
switches within their own network
> Create discipline specific re-configurable IP
networks
– Multihomed network which bypasses firewalls with direct connect
to servers behind campus router/firewall
UCLP Applications
> Korea, Ireland, Taiwan layer 1 transit
– Other countries under negotiation
> Layer 1 restoral and protections paths for ORANs
– BCnet, ORANO and RISQ
> 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
UCLP Applications- 2
> HEPnet – High Energy Physics IP network
> 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
> CERN Low level trigger data to UoAlberta
– 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
> Canada Light Source Synchrotron – remote streaming of data
acquisition to UoAlberta
– 2 to 5 Gbps continuously
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
