Information Model for Impaired Optical Path Validation

This document presents an overview of the information model for impaired optical path validation in Wavelength Switched Optical Networks (WSONs), as discussed at the 79th IETF meeting in Beijing, November 2010. It details the framework's ongoing developments, including new sections on properties for impairment models, encoding considerations tailored to G.697, and initial thoughts on computational model parameters. This draft emphasizes the significance of time and wavelength dependencies in impairment information for enhanced network performance. Contributions from industry experts are noted.

  1. Information Model for Impaired Optical Path Validation draft-bernstein-wson-impairment-info-03 Young Lee @ Huawei Greg Bernstein @ Grotto Networking Moustafa Kattan @ Cisco Giovanni Martinelli @ Cisco Andrea Zanardi @ Create-Net 79th IETF – Beijing, November 2010

  2. WSONs with Impairments: the *usual* flow Framework draft-ietf-ccamp-wson-impairments-04 (presented, on going) Info Model draft-bernstein-wson-impairment-info-03 To be updated Encoding draft-bernstein-wson-impairment-encode-01 79th IETF – Beijing, November 2010

  3. Changes 03 -> 04 • Added Section 2, “Properties for impairment info model” (e.g. time dependecies, wavelenght dependendecies, linearity etc.) • Section 4. Encoding considerations: updated to fresh new G.697 Appendix V. • Section 5. Start adding considerations regarding parameters for the computational model defined in the framework. 79th IETF – Beijing, November 2010

  4. Next Steps/Issues • Fill section 5 with proper information. • Updated Encoding draft accordingly. COMMENTS? (Thank you) 79th IETF – Beijing, November 2010
