Equipment modelKL/ND

Equipment model

  • Recap: Things we want to cover in the Equipment model
    • Equipment property specification, which is also part of the general spec model
    • Physical strand joint property. Raised in progressing the TAPI physical span model
      • TAPI physical strand joint property.
        • A lot of focus on optical impairment that didn't have good representation.
        • The joint. It could be via a connector or the strand can be spliced together. It is a point of weakness and reflection.
        • Fiber types. 
      • To extend the equipment model toward the physical space.
        • Could look at Chris' connector-pin-strand contribution (which updated to the TMF work). 
          • Lightweight model to augment the TAPI model
  • Two pieces
    1. Physical property model/spec
      • Common model/pattern for all/most specific physical properties, covering configurating, monitoring, reading, thresholding, alerting/alarming, reporting, recording, ...
        • Allow simplified application via folding away un-needed stuff
        • Applicable to specific properties, such as temperature, pressure, electric power, etc.
    2. Physical strand joint property model

Leo & CH commented on the  complexity of the model, many experimental material, and type invariant v instance invariant.

Focus on core model parts (Equipment and Holder) and relegate any experimental material to remove the tangle and ensure clear focus of the document.

Task terminologiesND

Task terminologies

Simplified Spec

Discuss Simplified Spec


  • RUST: Chris ran through
    • Algebraic data types (ADTs) 
    • Application: complex return types
    • Application: d-hoc data structures
    • Example: JSON
  • Nigel shared
    • Layout in JSONized YANG form
      • To do next, layout in JSONized YANG form, give another update next week
  • IETF/IEFF w.r.t. simplified Spec 
  • DSR NEP spec with 4 bidirectional ports
  • Combinatorial rules for LP options
  • Pruned spec model
  • Discuss RUST
