  1. Availability Model: status update Sofie Verbrugge

  2. Outline • Status • Collected availability numbers • Failure sources • Collected numbers energy consumption and footprint • Next steps Dept. of Information Technology, Ghent University - IMEC

  3. Status of the work • Goal • Come up with NOBEL reference availability numbers • Estimations of relevant availability numbers • Actions since last meeting (Paris) • Partners judged collected numbers • New inputs concerning theoretical sections • New inputs on power consumption and footprint section • New inputs on network wide availability section Dept. of Information Technology, Ghent University - IMEC

  4. Pre-final version of the document • Availability model • Considered technologies: IP, MPLS, SDH, optical, ASON • Overview of reliability prediction models • Availability and reliability numbers: • More details needed on SDH equipment • Network wide availability • No information for ASTN • Probably because not operational yet • Power consumption and footprint • Tables filled Dept. of Information Technology, Ghent University - IMEC

  5. Remains to be done • Editorial changes • Improve/ shorten section on operational processes • Current version of the section doesn’t fit too well in the document • New valuable input obtained Dept. of Information Technology, Ghent University - IMEC

  6. Outline • Status • Collected availability numbers • Failure sources • Collected numbers energy consumption and footprint • Next steps Dept. of Information Technology, Ghent University - IMEC

  7. IP MTBF[h]=10^9/FIT Dept. of Information Technology, Ghent University - IMEC

  8. SDH Dept. of Information Technology, Ghent University - IMEC

  9. WDM Dept. of Information Technology, Ghent University - IMEC

  10. OEO versus OOO switching systems Dept. of Information Technology, Ghent University - IMEC

  11. Fiber Dept. of Information Technology, Ghent University - IMEC

  12. ASTN Assumption: availability numbers of CP = IP router SW. BUT: impact of a failures is different (IP router: SW failure affects all connections) Dept. of Information Technology, Ghent University - IMEC

  13. Outline • Status • Collected availability numbers • Failure sources • Collected numbers energy consumption and footprint • Next steps Dept. of Information Technology, Ghent University - IMEC

  14. Failure sources Dept. of Information Technology, Ghent University - IMEC

  15. Outline • Status • Collected availability numbers • Failure sources • Collected numbers energy consumption and footprint • Next steps Dept. of Information Technology, Ghent University - IMEC

  16. IP Dept. of Information Technology, Ghent University - IMEC

  17. SDH Dept. of Information Technology, Ghent University - IMEC

  18. WDM Dept. of Information Technology, Ghent University - IMEC

  19. Outline • Status • Collected availability numbers • Failure sources • Collected numbers energy consumption and footprint • Next steps Dept. of Information Technology, Ghent University - IMEC

  20. Next steps • Prepare DRCN submission • Including availability numbers (document), e2e availability studies (AGH, T-Systems) • Deadline: April 15th • Prepare final version of the document • Updated section on operational processes • Try to submit longer paper including all numbers: also • energy consumption and footprint • network wide availability • operational processes • Include in NOBEL deliverable: D27?
