Nigel Davis Need specs for the DSR NEP (has 4 bidirectional ports) and the CEP above it to describe the flow (TR-547-TAPI Reference Implementation Agreement_v2.0_am.docx slide 16)
Nigel DavisCover combinatorial rule for layer protocol options. "And" & "Or" in spec language.
Nigel DavisTake the spec model, prune out the stuff that are not relevant to simple layer hierarchy, look at how to apply the general principles (slide 32) notation to the stack of layers & rules, write it in the context of the original spec structure. Note that the action "Nigel Davis To prune out the unneeded stuff from the current Spec document so that to show the Yang "when" and "must" of the Occurrence pattern. Action item from2021 Sep 07-10 : OIMT Virtual Face-to-Face" is covered by this action.
Nigel DavisConstruct simple spec example using layer hierarchy modelfor the OTN payload structure, try longhand form, correct number of occurrence set, based on some specific ports. Code it in JSON form of YANG. Note that the action "Nigel DavisLay out the spec model with sufficient occurrence pattern of equipment in it. Relate UML to Yang. Action item from2021 Sep 07-10 : OIMT Virtual Face-to-Face" is superseded by this action.
