DELIVERABLE 2.04

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.

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.

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

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”

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

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

ANY QUESTIONS ?

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
