Andrea Mazzini shows the updated diagrams regarding ROADM Path impairments.
- Below the simplest scenario, where the Node Rule Group indicates full mesh connectivity between all add/drop and degree ports, and the related impairment profiles as applicable to all possible connectivities:
- Below the diagram built during the discussion, where add/drop NEPs and degree NEPs are grouped by distinct Node Rule Groups and the impairments profiles are referred by the Inter Rule Group object:
- The figure above is an example of the agreed the solution where:
- one or more Node Rule Group instances aggregate only the add/drop MC NEPs,
- one or more Node Rule Group instances aggregate only the degree MC NEPs, and refer to the express-path profiles,
- one or more Inter Rule Group instances associates the above 1. and 2. Node Rule Group instances, to identify one or more add/drop to degree path impairments.
Below the UML model of Node Rule Group and Inter Rule Group:
- After some discussion agreed to make bidirectional the association between NEP and Node Rule Group classes.
- This shall allow both:
- GET on Node Rule Group instance including all the references to the NEP instances associated by the Node Rule Group Rule(s),
- GET on NEP instance including all the references to the Node Rule Group instances involving the NEP.
