  6. D2.04 Presentation on regions of increasing interest to Radio Astronomy and Networking • Provides an update on the network connectivity for: • Radio Telescopes in existing and new world regions. • Networking infrastructure of potential interest to Radio Astronomy • Information is provided for the following regions: • GÉANT: Pan European and a summary of connectivity to world regions • Links between Europe and the US – ACE & GÉANT • Africa • The Pan-Asia Region – the TEIN Network • Australia & New Zealand • Latin America • Russia • The presentation will be updated as new data becomes available. NEXPReS P2 Review – Brussels - 21 September 2012

  8. GÉANT Procurement and100Gigabit Rollout

  9. The GÉANT Procurement • Started at the beginning of 2010 with an RFI exercise (6 months) • Formal Competitive Dialogue procurement process at the end of 2010 in 3 lots • Technology agnostic approach to transmission • Did not specify DCM-based or DCM-free, ROADM specifics, etc • BUT service & operational feature prescriptions e.g“optimisation” for delivery of 100G; • in final ITT, suppliers mandated to include flexible, zero-touch provisioning of 10G “lambdas”(even if solution not supporting native 10G lambdas) • effectively meant include OTN switching • “Classical MPLS” approach to switching (lot 2) was mandated • Alternatives (MPLS-TP, PBB-TE) not sufficiently convincing during dialogue • Lot 3 dropped • Converged/integrated (“POTS”) solutions did not appear sufficiently convincing during dialogue • In addition we are re-procuring the dark fibres.

  10. We selected…(for transmission) • DTN-X solution from Infinera • Why? • Photonic integration • Large pools of “virtualised” BW • Ease of use • Excellent service wrap

  11. 100G Transmitters(Complex but very clever! ) Mach-Zehnder modulator 100G DC-PM-QPSK 38GHz 12.5Gbps inputs Carrier 1 Carrier 2 X X Y Y p/2 Carrier 1 Laser PBC Rot p/2 p/2 Carrier 2 Laser PBC Rot 50GHz p/2 A “dual carrier” 100G TX implementation 11

  12. 100G Receivers(they are even more complex!) TIA TIA Input signal: PM-QPSK Rx ASIC Rx ASIC Input signal: PM-QPSK PBS PBS 90-deg Hybrid 90-deg Hybrid A/D A/D DSP DSP (Carrier 1) A/D A/D A/D A/D 90-deg Hybrid 90-deg Hybrid LO Laser LO Laser A/D A/D PD PD (Carrier 2) A “dual carrier” 100G RX implementation

  13. 100G transceiversPhotonic Integration is key in a Terabit network Optical Functions Integrated >600 Fiber Connections Eliminated ~250

  14. We selected…(for switching) • MX series of IP/MPLS switch/routers from Juniper • Why? • Can provide wide array of switched services (based on EoMPLS) • Includes MP2MP as well as P2P • Optimised for Ethernet • Supports 100GE • 120Gbps/slot (new SCBs) • Also jolly good at routing… • …and ready for “virtualisation”

  15. Day-1 connectivity used by MXs and extant routers (high level view) Actually Infinera gives 500 Gbit PL RU SK CZ UK DE RO BG ES HR DK CH BE LT LV EE LU IE NL AT HU Fink FR SI IT PT KEY 100G lambda Nx10GE lambda Nx10GE lambda (detail TBD) Nx10G leased lambdas GR

  16. Planned new GÉANT architecture(principles) • Principles are: • Adopt 100G trunks to accommodate GÉANT IP load (partly) and GÉANT Plus load from day-1 (in W and E rings) • Where a POP has a router and MCC today then simply replace MCC with an MX960 • Where a POP has an MCC and no router then replace with two smaller MXs (480s) • Sub-10G GÉANT Plus instances implemented as VLLs on new Lot 2 platform (hence no STM-Ns) • Existing 10G GÉANT Lambdas will be migrated to Infinera platform (this will support the STM-64s) • Encourage new 10GE GÉANT “Lambdas” (now really higher capacity GEANT Plus instances) to be carried over new Lot 2 platform

  17. Switch Switch IP Router IP Router Inside the GÉANT PoPThe Hybrid GÉANT+ services Lambdas To NREN B To NREN A Lambdas IP Backup Primary IP Peering GÉANT+ IP Backup Primary IP Peering GÉANT+ Backup IP Peering for NREN A Dark fibre/amplifier chain GÉANT POP A GÉANT POP B

  19. Converged lot 2 and IP architectureat “day-2” (current vision) • By this stage DF lines expected to be carrying multiple 40/100G lambdas so GÉANT IP backups (or dual-homed IP primaries) can be transported directly to other POPs avoiding the single Lot 2 switch POP A POP B POP C IP primary DF line DF line Lot 2++ switch Lot 2++ switch Lot 2++ switch 100GE 100GE 100GE 100GE GÉANTLambda >10Gbps GÉANTLambda >10Gbps GÉANTPlus IP peer IP backup But need to think a bit more about how toget from “day-1” to this “day-2”safely

  20. RoadmapServices made available during 2012 20

  21. Rollout StatusBoD over GÉANT for NEXPReS • GÉANT+ • MX 960 installed in most PoPs • Customer access moved from MCCs to MXs • MX tromboned back to MCC • Trunks ready to move from MCC to MX • Converged IP and GÉANT+ • Dynamic Core (BoD) • Coding for AutoBAHN underway • Link transitions as above • Timescale New Year 2013

  22. New GÉANT DF footprint New GÉANT day-1 Dark Fibre footprint

  23. Any Questions ?

  24. Dinner • Susanne sent four suggestions: • 1) D/S Louise – (at Aker Brygge, which is the place to go) 10 min walk from here • 2) Lorry - That is a rather special place not very far from here - they serve good food and beer • 3) There is an Asian one called Dinner which is supposed to be good • 4) Tapas
