  1. Status update: submission of DRCN 2005 tutorial Ilse Lievens, Didier Colle (IMEC)

  2. DRCN tutorial info • DRCN TUTORIALS: • Half-day: 3 hours. • Contents proposal for tutorial: • Topic(s) • Objectives • Expected background knowledge of participants • Time allocations of major topics • Instructor(s)’ qualifications • Fit with conference theme • Proposal submission date: June 15, 2005 • Online submission • If accepted, tutorial due at: • beginning of September’05 • Conference date: • October 16-19, 2005 (Italy) Department of Information technology – Ghent University / IMEC

  3. Tutorial structure • Title: • Recovery in Multi-layer, Multi-domain and Multi-service core Networks • Outline: • Introduction • Survivability generics • Network scenarios • Single-layer survivability • Multi-layer survivability • Multi-domain survivability • Multi-service survivability • Conclusions 20 min 20 min 30 min 25 min 25 min 25 min 3 ‘main’ parts of the tutorial Department of Information technology – Ghent University / IMEC

  4. Open issues for submission on June 15th • Agree on speaker • Proposal: Piet Demeester (IMEC) • This was also proposed by Giuseppe Ferraris, DRCN’05 tutorial chair. • OK for all? • Submission document: • Should NOBEL be mentioned? • Topics in multi-service resilience part have to be completed: what, who? • Topics in multi-domain survivability: OK? • General: comments on the document? Department of Information technology – Ghent University / IMEC

  5. Tutorial topics (1/5) • Introduction • Impact of failures, traffic volume, failure rates, recovery actions [5 slides] • Survivability generics • Network recovery/reliability [1-2 slides, TBD IMEC] • Phases in a recovery process: recovery cycle, reversion cycle [1-2 slides, TBD Achim, Siemens ?] • Recovery mechanisms performance criteria [2-3 slides, TBD IMEC] • QoR [10 slides, AGH] • Why QoR, basic QoR parameters • Existing frameworks: description, pros/cons, limitations • OPEX/CAPEX in network recovery [6 slides, IMEC] • CAPEX & OPEX definition • OPEX subparts and operational processes • repair process and OPEX • OPEX results Department of Information technology – Ghent University / IMEC

  6. Tutorial topics (2/5) • Network scenarios/technologies [+/- 15 slides] • Layered view • Metro vs core: defining scope [1 slide, TBD IMEC] • IP • MPLS • NG-SDH [1 slide, TBD IMEC] • OTN Department of Information technology – Ghent University / IMEC

  7. Tutorial topics (3/5) • Single-layer survivability [+/- 30 slides] • General characteristics • Protection vs restoration [2 slides, Marconi] • Survivability classification overview [1slide: Marconi] • Other? • Survivability in IP • Restoration in IP • What in the higher layer • Typical resilient IP backbone network [1 slide, Marconi] • Survivability in MPLS • Global default protection and global restoration • FRR (local protection) [8 slides, TID] • Survivability in NG-SDH • LCAS for survivability [2 slides, TBD IMEC] • Survivability in OTN • Equipment protection; 1+1; ring protection; mesh protection • p-cycles: who ?? Department of Information technology – Ghent University / IMEC

  8. Tutorial topics (4/5) • Multi-layer survivability [+/- 25 slides, TBD IMEC] • Single-layer recovery schemes in multi-layer networks: • at the bottom layer; at the top layer; at the lowest detecting layer, and at the highest-possible layer • Static multi-layer recovery schemes: • uncoordinated approach; sequential approach; integrated approach; spare resources for multi-layer recovery; performance comparison of some recovery strategies • Dynamic multi-layer recovery (Intelligent optical networks) Department of Information technology – Ghent University / IMEC

  9. Tutorial topics (5/5) • Multi-domain survivability • Why multi-domain survivability • End-to-end protection • End-to-end protection in disjoint domains • Combined end-to-end and per domain protection • Protection of the interconnection • Topics OK??? • Multi-service survivability • Why? • QoR methodology • Other input required [Achim, Siemens ?] • NOBEL case studies: • Suggestion to leave this out: OK? • Conclusions Department of Information technology – Ghent University / IMEC

  10. Timing • Submission document • Last comments: June 14th • June 15th: online submission by IMEC • Tutorial slides • Munich meeting: discussion on draft set of slides (complete but not harmonised wrt format etc) • June ??: last call for missing input from partners • June 27: conference call to discuss new version • July: streamlining of tutorial by IMEC • August: round of reviews to complete the slides • September 2: submission Department of Information technology – Ghent University / IMEC
