  1. GÉANT2Network Infrastructure 12th October 2005, 4th EVN-NREN Meeting, Schiphol Airport, Amsterdam Michael Enrico Network Engineering & Planning, DANTE

  2. Reminder of Remit Procurement history (why so long?) Planned GÉANT2 build Equipment to do it Service overview Agenda

  3. Upgrade GÉANT (1) Reached end of 4-year funding cycle Possibility for greater infrastructure ownership (fibre) But requires longer term views than hitherto adopted Provide support for new services Not just a bigger IP network… …support for high-capacity P2P services… …and (if needed)…lots of them! Facilitate (joint) R&D efforts Extend geographical coverage GÉANT2 (GN2 I3) Remit

  4. Q4 2003 started drafting connectivity ITT Q1 2004 announced & issued ITT Apr/May 2004 first supplier meetings, “DF lighting” modelling June 2004 started on equipment & NOC ITT Sept 2004 GN2 contract (with EC) came into force first equipment supplier meetings Oct/Nov 2004 equipment suppliers shortlisted Dec 2004 connectivity suppliers shortlisted started hands-on “testing” of final 3 equipment suppliers first NREN engineer consultation workshop Jan/Feb 2005 further equipment “testing” March 2005 second NREN engineer consultation workshop Apr-June 2005 connectivity & equipment suppliers decided (LOIs issued) July 2005 contracts being finalised and signed Now building Review of Procurement

  5. GÉANT in 2005 (the starting point) Some Facts & Figures… • 21 POPs • serves 29 European NRENs • 16 x 10G lambda • 13 x 2.5G “lambda” • + some lower speed links • Juniper M160 & M40 routers in POPs with • NREN accesses at up to 10Gbps (+ backup) • 12G to North America • POP in NY • connections to R&E networks in: • USA, Canada & Japan • AND Mediterranean • AND Latin America • AND (soon) South East Asia

  6. 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…

  21. Services

  22. Continue to support usual IP services BE, LBE, PIP, mcast (v4), v6, mcast (v6) Enhance these with: implementation of new features as required and available e.g. embedded RP for IPv6mcast improved performance monitoring (JRA1 & SA3) more automated PIP provisioning (SA3) network security best practice (JRA2) Continue to support emulated L2 P2P services L2VPNs for lower capacity [“lightpath”] support Add portfolio of new L1 and L2 P2P services cost-effective support for high-capacity [“lightpath”] services up to 10G (for now) emphasis placed on support for Ethernet framing experiment with translational P2P service support e.g. native gigE to GFP VC-4-7v over SDH experiment with support for various protection modes Headlines
