  1. IGTMDréunion du 4 Mai 2007CC IN2P3 Lyon Bernard.Tuy@renater.fr

  2. Contribution de RENATER • Mise en place du lien • CC IN2P3, Lyon - Fermi Lab, Chicago • Mise en place outils de supervision • Gestion des erreurs et des TTs

  3. Etat du circuit IN2P3 - FNAL • Pbs entre Géant et HOPI ? • 2 liens migrés sur le Paris - NY • Retour manuel sur Paris - Londres en cas de besoin • Pbs de nommage des interfaces ? • Plusieurs TTs par jour … • Statistiques • Cf graphes (débit 2 VLANs agrégés)

  4. Usage du circuit

  5. Monitoring • http://lhcopnmon1.fnal.gov:9090/FERMI-E2E/G2_E2E_index.html • http://lhcopnmon1.fnal.gov:9090/FERMI-E2E/G2_E2E_view_domain_IN2P3.html • http://lhcopnmon1.fnal.gov:9090/FERMI-E2E/G2_E2E_view_e2elink_FERMI-IN2P3-IGTMD-00X.html • X={1,2}

  6. TTs • 2007-04-25T15:35:01.0-6:00 BGP status for Neighbor: IP=198.151.133.153 • 2007-04-25T15:35:01.0-6:00 BGP status for Neighbor: IP=198.151.133.157

  7. E2E circuitsDebriefing... jerome.durand@renater.fr

  8. Building e2e circuits • This is complex • Synchronization required • Service offered has strong impact on network architecture • Monitoring not straightforward • What for ? • Provide more bandwidth ? • Provide 100% private circuit ?

  9. About setup • Several months needed • Hours of conf calls • Agreement required all over the path • VLAN IDs ... • Private addresses usage • Will we do better next time ?

  10. Provide more bandwidth ? • True for 10GE circuits • What about 1GE ? • We can set up 1 Gbps IP traffic much more easily

  11. Provide 100% private circuit ? • We have Ethernet switches on these circuits • Equipment handles other traffic too • No prioritization used (in Renater so far) • Some use EoMPLS • Some others have IP over MPLS  • And this differs in all parts of the circuit

  12. What about monitoring...and day to day operation • Very complex! • Difficult to find where the problem comes from • We had to configure private addresses on equipment on the path! • Good this was multipoint circuit  • Privacy issue ? • perfSONAR  + E2ECU + ...

  13. And about resiliency ? • Almost no resiliency available • And outages are often very long to manage • Up to 3 days !

  14. And what for ? • Customers do IP at the edge and have a BGP peering !

  15. Requirements to establish E2E circuits • Define end to end locations • Circuit type to be validated and decided by the NREN • VLAN &/or EoMPLS • PIP E2E • Lambda E2E • L3 VPN • Define services and apps which flow through the circuit • IPv4, IPv6, Unicast, Multicast … • MTU requirements • Specify IP address plans (private or not) • Define BW and SLA requirements for the E2E circuit • Jitter, OWD, BW, … • Who pays what ?
