Connect. Communicate. Collaborate
Building and developing international future networks
Roberto Sabatino, DANTE
HEANET conference, Athlone,
10 November 2005
Connect. Communicate. Collaborate
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
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

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