Connect. Communicate. Collaborate Building and developing international future networks Roberto Sabatino, DANTE HEANET conference, Athlone, 10 November 2005
2
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. Collaborate 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
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
5
Connect. Communicate. Collaborate The multidomain challenge for GE Connect. Communicate. Collaborate GEANT2 NREN-ANREN-B GE 10 GE STM-64 10 GE
6
Connect. Communicate. Collaborate The multidomain challenge for 10 GE Connect. Communicate. Collaborate GÉANT2NREN-ANREN-B 10 GE STM-64
7
Connect. Communicate. Collaborate The technology challenge 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 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 Data Mapper 4x 10GE LAN board in 1678MCC Data Mapper MAC O/E BKP dr Data Mapper Data Mapper MAC O/E Data Mapper Device - GFP-F into VC-4-nv - GFP-F into ODU1/2 4x10GE LAN interface ports To matrix 10GE-LAN interface board in 1678 MCC

Connect. Communicate. Collaborate GFP-F Mapping (G.7041)
11
Connect. Communicate. Collaborate Development programme End to end QoS and Performance Security BW provision Mobility
12
Connect. Communicate. Collaborate 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

Connect. Communicate. Collaborate Performance measurement Connect. Communicate. Collaborate
14
BW provision, on demand
15
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
16
Connect. Communicate. Collaborate Define Information Flows (and process logic) Domain 1Domain 2 AZBC Service description TYPE: 1 (Ethernet) FROM: ATO: Z BW: 1Gbps Start: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?
17
Connect. Communicate. Collaborate 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
Connect. Communicate. Collaborate Mobility AAA Roaming Single sign on
19
Connect. Communicate. Collaborate 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
