1 Optical Networks and eVLBI Bill St. Arnaud bill.st.arnaud@canarie.ca

2 CANARIE Inc.- Overview Federal leadership: Concept born in 1990 out of Industry Canada discussions Founding: Incorporated in 1993 by industry and academia Funding: From Industry Canada: For networks and research applications from Canadian Heritage, HRDC, Health Canada Mission: To facilitate development and use of Canada’s advanced communications infrastructure Primary stakeholders: Government Departments, universities, provincial research networks, broader research community, colleges, carriers, IT sector, SMEs, broader education sector, broader health sector, provinces

4 CA*net 4 Drivers Application Specific Networks >Soon high end grid applications will have sufficient traffic volume to require their own underlay networks ”Complementing” routed networks – Not a replacement for routed networks – only increasing the direct peering mesh of the routed network for specific applications – But peering may be more dynamic (and not globally advertised) than traditional IP BGP peering >Discipline or applications specific networks – VBLI grids like European EVN – High energy physics grid – Ultralight – NEES grid, Bio-informatics Grid, etc

5 eVLBI driving network architectures >MERLIN in UK links several radio dish sites with optical fiber network >European EVN and LOFAR will built around optical lightpaths on GEANT network >In Canada eVLBI is mostly used for Geodetic applications – GPS corrections – Measuring movement of Canadian shield >DRAO (astronomical dish) will be soon connected to CA*net 4 network so that they can participate in global eVLBI

7 Example – EVN traffic flows over GEANT UK SE FR NL BE DE1 DE2 CZ PL CH IT AT SURFnetJANETGARRPSNCDFN NORDUnet 2.5G 10G JIVE Provided courtesy of Dai Davies

8 Issues >How do you charge for bandwidth and usage when single application traffic dwarfs all other IP traffic? >Possible solutions: 1.GMPLS (with QoS) Requires expensive routers and complex coordinated central management to setup and tear down tunnels Interdomain still unproven 2.Optical overlay/underlay –ASON – same problems as GMPLS 3.Application specific UCLP networks – Increase BGP mesh for specific applications or disciplines

9 UCLP applied to EVN UK SE FR NL BE DE1 DE2 CZ PL CH IT AT SURFnetJANETGARRPSNCDFN NORDUnet JIVE EVN sites will see 2 BGP routes to SURFnet: -the normal IP route over GEANT -Express route using dedicated lightpaths (in green) Express route

10 What is UCLP? >User Controlled LightPaths – a configuration and provisioning tool built around web services >Third party (e.g. eVLBI) can concatenate cross connects together from various networks to produce a wide are network that is under their control – Articulated Private Network (APN) >Uses Service Oriented Architecture (SOA) and so network can be integrated with other web service applications such as instruments and software correlators >Allows eVLBI users to change configuration and topology of the optical network to meet research needs
