  3. Tutorial structure • Title: • Recovery in Multi-layer, Multi-domain and Multi-service Optical Networks • Outline: • Introduction • Survivability generics • Network scenarios • Single-layer survivability • Multi-layer survivability • Multi-domain survivability • Multi-service survivability • NOBEL case studies? • Conclusions Department of Information technology – Ghent University / IMEC

  4. Tutorial topics (1/3) • Introduction • Impact of failures, traffic volume, failure rates, recovery actions [+/- 5 slides] • Survivability generics • Network recovery/reliability • Phases in a recovery process: recovery cycle, reversion cycle • Recovery mechanisms performance criteria • QoR: • Reliability requirements for various users and services • Existing frameworks: description, pros/cons, limitations (AGH) • OPEX/CAPEX in network recovery [+/- 5 slides] • CAPEX: motivation for efficient resource sharing; penalties to be paid to clients (QoR) • OPEX: manual rerouting of traffic; repair of infrastructure • Numerical Example ? • Network scenarios • IP; MPLS; OTN [+/- 10 slides] • Other ??

  5. Tutorial topics (2/3) • Single-layer survivability • Generic characteristics: backup capacity vs shared, protection vs restoration, … • Characteristics of single-layer recovery mechanisms in: IP, MPLS, OTN [+/- 25 slides] • Multi-layer survivability • 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
