update on ca*net 4 network [email protected]
TRANSCRIPT
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
> 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
UCLP Applications- 2
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
