  1. GÉANT now and next steps NORDUnet 2002 Conference Copenhagen15th of April 2002 Agnes Pouele, Network Engineer DANTE

  2. Introduction to GÉANT GÉANT topology GÉANT peerings GÉANT services Multicast IP premium Other activities Long term views Agenda

  3. Introduction to GÉANT • GÉANT is a 10 Gbps Pan-European Network that supports the development activities of the European National Research & Education Networks (NRENs) • GÉANT was launched in December 2001 and is the successor of TEN-155

  4. Estonia Latvia Lithuania Slovak Rep. Romania Israel Cyprus

  5. We have currently 19 PoPs across Europe 2 New PoPs under construction: Israel and Croatia Trunks 9*STM64 in West of Europe 12*STM16 in West and East of Europe. GÉANT Topology

  6. Accesses to GÉANT 12 connections at STM16 POS capacity 10 connections <= to STM1 capacity GÉANT Topology

  8. GÉANT Connections • 27 National network research peerings

  9. GÉANT Research Interconnections CAnet Esnet STM-4 Abilene GTREN www.dante.net/nep/gtren.html DFN STM-16 GÉANT AS20965 JANET DE UK NREN2 NREN4 ... ... GTREN is the Global Terabit Research & Education Network initiative of DANTE and UCAID to establish an intercontinental network connecting the various regional research networks.

  10. Future Connectivity • EUMEDConnect Project (36 months) • Part of the Euro-Mediterranean Information Society (EUMEDIS) initiative • EuropeAid (EC) funded programme • Beneficiaries are most of the North Africa and Eastern Mediterranean states • EUMEDConnect aims to provide the necessary network infrastructure • Will provide intra-regional connectivity and connectivity to GÉANT • Phase 1 (until end of April)

  11. Caesar project Same type of project but for South of America Future Connectivity

  12. GÉANT Services • GÉANT Standard IP Service • Ip traffic from NREN to NREN (About 27 countries) • IP traffic from NREN to Research Peerings (Abilene, Canarie, Esnet, NII ..) • Commodity peerings • Commodity IP users to Commercial Peerings (KPNQwest, Global Crossing, Infonet)

  13. Multicast Service Multicast is enabled for all the NRENs and Research Peerings Replacement of the Managed Bandwidth Service Premium IP Service (End to End Service for low Delay, low Jitter, negligible loss). VPN layers 2 GÉANT Services

  14. Upcoming New Services Security and Dos attack detection IPV6 GÉANT Services

  15. GÉANT MULTICAST SERVICEwww.dante.net/nep/GÉANT-MULTICAST/

  16. Coverage • GÉANT is a transit domain for Multicast traffic as well. • 24 NRENs over 27 have explicitly asked for being enabled multicast • Fully enabled with the Research peerings

  17. Via the primary access to GÉANT Via a GRE tunnel (currently nobody) Support of PIM-SM v2 only MBGP/MSDP/PIM-SM v2 peering Access to the Service

  18. Currently under definition Goal: fully supported service as Unicast. Monitoring of the infrastructure via a set of adapted tools. Beacon Matrices http://beaconserver.GÉANT.net:9999/ http://beaconserver.GÉANT.net:19999/ Looking glass =>http://www.dante.net/nep/lg/ Others (volume, MSDP, MBGP …) Operational procedures

  19. Troubleshooting Extension of the trouble ticket systems to multicast incidents Establishment of a database of Incidents “Sanctions” for mis-behaving customers ... Operational procedures

  20. IP PREMIUM SERVICEhttp://www.dante.net/sequin/

  21. IP Premium Service • This service which is currently being piloted in GÉANT has the aim to provide international Virtual leased line based on Diffserv. • The Premium IP service is an end-to-end service (University to University) crossing multiple administrative domains • It is defined on the basis of the Diffserv Expedited Forwarding Per Hop behavior which is required to offer • Bandwidth, low loss, upper bounded delay and jitter

  22. Premium IP packets are tagged with DSCP code =46 at the entrance of GÉANT Domain. Rate Limitation is applied per aggregate on the NREN’s access, based on the total demanded bandwidth towards the destination. Filters are made on two parameters (NRENs networks + DSCP value) IP Premium model

  23. Admission Control is made manually based on the Sum of bandwidth already booked on the destination access. IP Premium model

  24. IP Premium:Virtual Leased Line service SE NREN Janet UK AS786 Rate limitation is applied on the NREN access AS20965 GÉANT backbone Regional Network DE A DFN AS680 Admission Control  streams < 5 % of the BW access FR Regional Network B Tagging DSCP=46

  25. H.323 (CH, IT, DE) AQUILA (IST) (AT, PL) MOICANE (IST) (IT, GR, PT, RO) Premium IP tests

  26. Other activitiesSecurity(http://www.dante.net/security) dancert@dante.org.uk

  27. DANCERT(DANTE’s Computer Emergency Response Team) Team responsible for defining and implementing DANTE security policy. DoS attack service protection Proactively through rate limiting and anti-spoofing measures. Reactively through DoS tools applying filters and helping report and investigate attacks. Assistance in investigating security incidents such as: Hacking, Port Scanning, Spam reports

  28. Other activitiesIPV6(http://www.6net.org)

  29. 36 Month project started in January 2002 Participants Cisco (coordinating partner) DANTE (GÉANT), NRENs, other organisms Testbed for activities using/supporting native IPv6 Interconnection of national IPv6 testbeds Support for applications which exploit IPv6 (eg mobile) Demonstration of complete native IPv6 stack IPV6: 6NET project

  30. Planned Y1 6NET topology • Native STM-1line to Greece under negotiation • International IPv6 connectivity provided by partners including DANTE to NACSIS Testbed for activities using/supporting native IPv6

  31. Upgrade of the core network from 10 Gbps to 40 Gbps. With one Lambda? With several Lambda's? Provisioning of Soft permanent channels to build Virtual Optical Private Network GÉANT Long term views

  32. Questions ? Thanks
