1. Update on CA*net 4 Network Bill.st.Arnaud@canarie.ca

3. 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 >3 rd 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

4. 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

5. 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

6. >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

7. 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

8. Today’s hierarchical IP network ORA N University Region al CAnet 4 World

9. Tomorrow’s peer to peer IP network ORA N University Region al CAnet 4 Anybody can peer with anybody Server World

10. CA*net 4 == Internet 3? CAnet 4 Commodity Internet ORAN University CERN University GigaPOP UltraLight eVLBI Dept Only possible with DWDM network

11. Taiwan Ireland GigaPOP STAR LIGHT CA*net 4 User controlled topology Seattle Taiwan Taiwan control switch directly using UCLP software NYC Ireland

12. Barcelona - Ottawa CA*net 4 Ottawa CRC Barcelona controls switches in both i2CAT and CA*net 4 directly using UCLP software Barcelona i2Cat GEANT RedIRIS MPLS tunnel (set up manually) New York
