connect communicate collaborate 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.

connect communicate collaborate GÉANT Procurement and 100Gigabit Rollout

connect communicate collaborate 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.

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

connect communicate collaborate 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” 14

connect communicate collaborate 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 16

connect communicate collaborate Converged lot 2 and IP architecture at “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 Lot 2++ switch DF line 100GE GÉANT Plus GÉANT Lambda >10Gbps GÉANT Lambda >10Gbps 100GE IP peer IP backup IP primary POP APOP BPOP C 100GE But need to think a bit more about how to get from “day-1” to this “day-2” safely 19

connect communicate collaborate ANY QUESTIONS ?

connect communicate collaborate 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
