  1. FM for Optical Transparent Network Fault Management For Optical Transparent Network Abdelkader Hajjaoui Lucent Nederland NOBEL / WP4June 13/14/15, 2005, Bell Labs Europe

  2. FM for OTN • Next Generation Optical Network • OPM status • Probable Causes • Fault Management Use Cases Bell Labs Europe

  3. Transparent optical Network • Increase transport capacity. • Reduce Cost • Phonic switch instead of electric switch • More transparency • Enhance QoS • Increase complexity for CP and MP Bell Labs Europe

  4. OPM • Physical Parameters are identified • Requirement for CP and MP • Probable Causes for FM • SLA as Application example for OPM Bell Labs Europe

  5. Ethernet IP/MPLS Digital Clients ATM SONET/SDH Optical LayerNetwork Optical Layer Network Optical Channel Layer Optical Multiplex Section Layer Optical Transmission Section Layer Fibre Physical Medium OTN Layer Network Bell Labs Europe

  6. Physical Performance Parameters • Optical Monitoring Parameters • Channel Power • Total Power • Optical Signal Noise Ratio (OSNR) • Channel wavelength • Q-Factor • BER = f(Q-Factor) Bell Labs Europe

  7. Probable Causes LOS, LOS-P, FDI-P, FDI-O, OCI DSR OCH LOS, LOS-P, FDI-P, FDI-O, BDI-P, BDI-O,PMI, OMS LOS, LOS-P, TIM, BDI-P, BDI-O,PMI, OTS Phy NE1 Bell Labs Europe

  8. OXC OXC Fault Management Digital Client Digital Client • 1 cable with 160 fibers • 1 fiber with 800  • 128 000 connetions • Huge data could be lost • Fast Fault localization is required • Fast correlation is required Bell Labs Europe

  9. Next steps • Decompose ONE into : • Optical Component relevant for FM ( May be input from IM) • Monitoring component (detect/measure OSNR/Power…) • Analyze 2 use cases • Failure due to a fiber cut (Detection+Reaction) • Failure due to performance degradation (prevent+Detection+Reaction) • Analyze FM for GMPLS (Discussion) • LMP (Hello msg) Per Fiber / per Lambda ???? Bell Labs Europe

  10. Optimizing OTN • Optimizing in-service optical transport network • Max capacity / Min costs • GMPLS with Policy Management (auto-reprovisioning / restoration) • Multi-layer (For discussion) • Inter-domain (E-NNI) Improve GMPLS performance Bell Labs Europe
