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

  2. 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…

  3. GÉANT2 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

  4. 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

  5. Connect. Communicate. Collaborate The multidomain challenge for GE NREN-A NREN-B GEANT2 STM-64 GE GE 10 GE STM-64 10 GE

  6. Connect. Communicate. Collaborate The multidomain challenge for 10 GE NREN-A GÉANT2 NREN-B STM-64 10 GE 10 GE 10 GE

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

  8. Connect. Communicate. Collaborate GÉANT2 PoP example

  9. 10GE-LAN interface board in 1678 MCC 4x 10GE LAN board in 1678MCC Data Mapper Generic solution: • Rate adaptive mapping into VC4-nv with flow ctrl. and LCAS, n=1..64; • up to 4 ports per board Full 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. O/E MAC BKPdr MAC O/E Data Mapper Data Mapper O/E MAC MAC O/E Data Mapper To matrix 4x10GE LAN interface ports Data Mapper Device - GFP-F into VC-4-nv - GFP-F into ODU1/2

  10. GFP-F Mapping (G.7041)

  11. Development programme • End to end QoS and Performance • Security • BW provision • Mobility

  12. Performance 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

  13. Connect. Communicate. Collaborate Performance measurement

  14. BW provision, on demand

  15. 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

  16. Define Information Flows(and process logic) 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? Can you (Domain 1) provide me with BoD service type one (Ethernet) from A to Z with this BW between these times, etc…? Service description TYPE: 1 (Ethernet) FROM: A TO: Z BW: 1Gbps Start:Stop: etc Domain 1 Domain 2 A B C Z

  17. Security • 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

  18. Mobility • AAA • Roaming • Single sign on

  19. Conclusions • 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
