  2. Motivation • Restart on “WSON with Impairment Validation”: • Standby due to on wson-rwa discussions • Proposal: reuse same “approach” as wson-rwa. • First step: 00 version submitted in July (01 on going) • Interested people, please join! IEFT85 - Atlanta

  3. WSON: RWA vs. RWA-IV Framework • RFC6163 • draft-ietf-ccamp-rwa-info • draft-ietf-ccamp-general-constraint-encode • draft-ietf-ccamp-rwa-wson-encode • RFC6566 • draft-martinelli-ccamp-wson-iv-info • draft-martinelli-ccamp-wson-iv-encode Info Model Encoding IEFT85 - Atlanta

  4. Info Model(draft-martinelli-ccamp-wson-iv-info-00) • RFC6566 Defines the Linear Impairment case as “in scope” (sec. 4.1, Scenario C) • ITU references: • ITU G.680 defines the computational models • ITU G.697 defines the encodings • Draft does not repeat information already in ITU documents. • Introduction of “Impairment Matrix” as a generalization of “Connectivity Matrix” IEFT85 - Atlanta

  5. Info Model (cont. 1) Connectivity Matrix (from WSON RWA info model): ConnectivityMatrix ::= <MatrixID> <ConnType> <Matrix> To further details, ConnectivityMatrix::= <MatrixID> <ConnType> ((<LinkSet> <LinkSet>) ...) This draft defines: ImpairmentMatrix ::= <MatrixID> <ConnType> ((<LinkSet> <LinkSet> <ImparimemtVector>) ...) IEFT85 - Atlanta

  6. Info Model (cont. 2) • <ConnType>: new value defined, “2” for Impairment Matrix • <ImpairmentVector> • This is the way to represent all impairment information associated with a Link-Set pair. • Details goes into encoding draft IEFT85 - Atlanta

  7. Encoding(draft-martinelli-ccamp-wson-iv-encode-00) • The details the Impairment Matrix and Vector 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Connectivity | MatrixID | Reserved |W|N| +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Link Set A #1 | : : : +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Link Set B #1 | : : : +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Optical Parameter TLV(s) | : : : +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ MATRIX VECTOR IEFT85 - Atlanta

  8. Encoding (cont.) • The Optical Parameter details 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | ParamSource | ParamID | Reserved |W| +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Value | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Variance | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Parameter “Source” and “ID” as per ITU G.697 IEFT85 - Atlanta

  9. Next Steps • Solicit comments and contribution from WG. • Refinements on both Info Model and Encoding (e.g. Parameters List, Wavelength Dependency, Link vs Node information). • Approach needs validation through ITU Liaison? IEFT85 - Atlanta

  10. Thank You! Impairments Made Simple IEFT85 - Atlanta
