GÉANT(1) → GÉANT2

Some New Facts & Figures…

• 25 POPs (+4)• to serve 30 NRENs (+1)• 11600 km of fibre• 140+ ILA sites• 50+ x (own) 10G lambdas• 9 x (leased) 10G lambda• 8 x 2.5G (leased) “lambda”• + some lower speed links • Juniper T640, M160 & M40

routers in POPs with• NREN accesses at up to 10Gbps

(+ backup) + P2P• 4 x 10G to North America• POP in NY• connections to other R&E

networks as before…

Connect. Communicate. CollaborateGÉANT2 focus

• Make large amounts of capacity accessible( technically, economically) to users

• taking network services a step further:– Ethernet (GE and 10GE), as service and as access

technology– Performance (monitoring and enhancement)– BW provision– Security– Mobility


The importance of Ethernet

• As end to end service and access technology

• It’s cheap and fast but how do we guarantee quality end to end across Europe ?

• Challenge to GÉANT2, NRENs and equipment vendors

• Mapping of 10Gigabit Ethernet to guaranteed QoS– Ethernet in the TDM domain (GFP, VCAT, LCAS..)– Development of next-generation SDH/SONET

Generic solution:

• Rate adaptive mapping into VC4-nv with flow ctrl. and LCAS, n=1..64;

• up to 4 ports per boardFull rate option:

• Ethernet full rate up to VC4-68v, flow ctrl. and LCAS for n<68

OTH option:

• Mapping into ODU1/2 with flow ctrl.

Connect. Communicate. CollaborateDevelopment programme

• End to end QoS and Performance• Security• BW provision• Mobility

Connect. Communicate. CollaboratePerformance enhancement

• A dual development program:– Help end users make the most of the network, via the

PERT (Performance Enhancement Response Team)• Relies on multi-disciplinary experts• human-on-the job at all times (the case manager)• Knowledge-base and trouble tickets

– Provide detailed, end to end performance measurement data

• Measurement probes scattered throughout the network

• Multidomain operation


Performance measurement Connect. Communicate. Collaborate

Connect. Communicate. CollaborateBW provision, on demand


How do we get there ?BOD workplan

– build a “common service description” in conjunction with other related projects (e.g. NSF DRAGON)

– define manual processes, their IO and internal logic• e.g. parameters required from a user as part of their

BoD service request– gain experience, refine– draw up templates (for IO) and flow charts (for

processes)– Automate the process


Define Information Flows(and process logic)

Domain 1 Domain 2A ZB C

Service descriptionTYPE: 1 (Ethernet)FROM: A TO: ZBW: 1GbpsStart: Stop:etc

Can you (Domain 1) provide me with BoD

service type one (Ethernet) from A to Z with this BW between these times, etc…?

Hold on, let me see… how do I get to Z? Via Domain 2 attached at B.

Can I do A-B? Yes. Can you (Domain 2) extend an instance of service type one from C to Z with

this BW between these times using this handoff method, etc?

Connect. Communicate. CollaborateSecurity

• Strengthen operational co-ordination and co-operation between GN2 partners for incident handling and resolution– Development, evaluation of tools– Establish operational procedures with SLAs

• Define an EU wide policy on security, make sure there are no weak links

Connect. Communicate. CollaborateMobility

• AAA

• Roaming

• Single sign on

Connect. Communicate. CollaborateConclusions

• The investment in dark fibre is the enabler for access to and management of large amounts of capacity

• The mixed (routed + switched) network architecture is the enabler for service provision

• The development programme is focussed on taking network services a step further
