Connect. Communicate. Collaborate

Building and developing international future networks

Connect. Communicate. CollaborateGÉANT(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

Connect. Communicate. Collaborate

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

– 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

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

Connect. Communicate. Collaborate

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
