1 GÉANT Support for Research Within and Beyond Europe TNC 2003, Zagreb May Marian Garcia, Operations Manager DANTE
2 AGENDA GÉANT Global Research Connectivity Europe, North America and other regions GÉANT services GÉANT Projects support: GRID Application
3 What is GÉANT? Pan-European Network connecting 28 NRENs from across Europe Jointly funded by NRENs and EC Based on 10Gbps capacity, using mainly Juniper routers Global Research connectivity US, Canada, Japan Platform for development and deployment of advanced services (QoS, IPv6, MPLS)
4 Multi-Gigabit pan-european Research Network Backbone Topology December 2002 Connecting 32 European Countries and 28 NRENs Backbone capacity in the range of: 34Mb/s-10Gb/s
5 Global Research Connectivity 3 x 2.5Gbps connectivity between Europe (AT, DE, UK) and US (NYC, DC) Interconnections with Abilene, CA*net4, ESNET, SINET NSF funded initiative to provide 2 x 2.5Gbps between Chicago and Amsterdam 155Mbps connection London-Tokyo
6 New access to Russia Other Regions South America (ALICE project) Mediterranean (EUMEDCONNECT project) South-East Europe (SEEREN project)
7 The ALICE Project America Latina Interconectada Con Europa The objective of ALICE is to create a regional Latin American research networking infrastructure and its interconnection to GEANT. The ALICE project is co-funded by the European Commission. Go into View / Master / Slide Master and replace this with: TITLE of presentation -- your NAME (your ADDRESS)
8 Possible Latin American network topology Major connectivity between AR, BR, CL, MX (at least 45 Mbps) Other countries connect to major nodes (between 10 and 45 Mbps) Connectivity to Europe at least 155 Mbps end 2003 Topology dependent on result of the ALICE tender Sustainability after 2006 to be ensured by CLARA (Cooperacion Latino Americana de Redes Avanzadas)
9 EUMEDCONNECT NREN s in Argelia, Cyprus, Egypt, Israel, Jordan, Lebanon, Malta, Morocco, Palestinian Authority, Syria, Tunisia, Turkey Project Partners DANTE (UK), GARR (Italy), GRNET (Greece), RedIRIS (Spain), RENATER (France) Project supported by EC EUMEDIS programme
10 How do we get there? Topology to be agreed during tender negotiations Initial topology could include: Direct MED-NREN connections to GÉANT Satellite links local hubs Timescales: Tender currently underway Service from late
11 AGENDA GÉANT Global Research Connectivity Europe, North America and other regions GÉANT services GÉANT Projects support: GRID Application
12 The Services Best Efforts IP MPLS-based VPNs Premium IP IPv6 LBE (scavenger) Multicast Interdomain Performance Monitoring
13 Use of Premium IP Separate IST project (SEQUIN) for the definition of Premium IP Validated, deployed on GEANT Based on diffserv-ef IST projects AQUILA, MOICANE, LONG Request for and configuration is not yet automated ongoing work
14 Use of L2 VPN Provision of emulated switched point to point connections, using Juniper MPLS/CCC 6NET: STM-1 between Germany and Greece ATRIUM: STM-16 between Poland and France DATATAG: 1GE between CERN and Italy
15 IPv6: Roll-out plan GÈANT v6 Core Configuration February 2003 First Connections April 2003 Pilot service June 2003 IPv6 production service October 2003
16 IPv6 Design One IGP => IS-IS handling v4 and v6 routes With a congruent topology for both protocols BGP Design => One TCP session for v4 and v6? Advantage: TCP sessions not duplicated Disadvantage: Next hop chosen by IPv6 NLRI is derived form the IPv4 address => Not real IPv6 address exchanged by IGP. Use static routes! Two TCP sessions!!
17 Addressing Plan 2001:0798/32 has been allocated by RIPE 2001:0798:0/35 for 6NET 2001:0798:2/35 for GEANT 2001:0798:4/35=> For delegation of /40 and /48 for projects 8 ranges of /36 reserved for NRNs delegation 2001:0798:E/35 => reserved for Migration
18 Current Status GÉANT core dual stack Already connected RedIRIS, RENATER, FCCN, SURFnet, HEANET, GARR, LITNET and Abilene Next days Rest of NRENs
19 AGENDA GÉANT Global Research Connectivity Europe, North America and other regions GÉANT services GÉANT Projects support: GRID Application
20 Largest GRID Application on GÉANT yet VLBI - Very Long Baseline Interferometry e-vlbi - Real-time VLBI done using network interconnectivity EVN - European VLBI Network 14 radio telescopes in Europe plus others further afield JIVE - Joint Institute for VLBI in Europe hosts Mk IV correlator (dedicated supercomputer) JIVE hosted by ASTRON at Dwingeloo in The Netherlands See
21 What is VLBI? Radio telescope Correlator Data flows (RT or non-rt)
22 Current arrangement uses tapes... Tape technology nearing EOL One supplier left $1200 per tape Drives no longer available Expensive logistics Effectively limits bit rates Hence limits resolution Slow turn around time Real-time measurement not possible Inflexible duty cycles
23 EVN Traffic Flows over GÉANT SE NORDUnet JANET UK JIVE PL SURFnet CZ PSNC BE NL DFN DE1 DE2 FR CH AT 2.5G 10G IT GARR
24 Who is supporting the PoC? Radio astronomy community (EVN) JIVE Radio telescope sites: NRENs Westerbork (NL) Effelsberg (DE) Onsala Space Observatory (SE) Medicina (IT) Jodrell Bank (UK) Torun (PL) GARR, UKERNA, DFN, NORDUnet (SUNET), PSNC SURFnet (all roads lead to Dwingeloo!) DANTE BACK
