East/West APIs YANG models
Transport PCE is based on a modular structure. Some of the bundles are tightly connected to the type of equipment handled by the controller. This is the case of the Renderer and the OLM that allow configuring OpenROADM equipment. Thus the algorithms of the different functions they implement, respect the procedure defined in the OpenROADM Device white paper.
Some other modules are less tightly coupled to the type of controlled equipment, such as the PCE and the Topology discovery. To ease further evolution Transport PCE specific models are published on the following Github repository: https://github.com/transportPCE/transportPCE_Public
Published models define a common base allowing the different modules to share the information present in the DataStore and to communicate. They can be used as a reference by contributors to develop complementary/additional features. These new features as far as they rely on the reference model could be triggered from existing module, in place of others having the same functionality for different kind of equipment, or to complement existing functions.
As an example we could imagine extending the support of equipment following different models. This would imply to develop some specific OLM & Renderer to configure the devices and to extend the topology model through additional augmentations.
