OTSi Information in the Flexi-grid tunnel model #40

Closed italobusi closed 2 months ago

Moreover the knowledge of the OTSi position in the spectrum is also useful in the intermediate nodes to easy the Optical Channel Monitoring in the ROADM."

I think this piece of text is very important when discussing the information to be provided by the controller (or by the control plane) to a ROADM during path setup. However, I am not sure this has an impact to the information to be provided in the topology model for path computation. My proposal is not to put this sentence in this draft but to open an issue to discuss this sentence in the context of tunnel setup: https://github.com/ietf-ccamp-wg/draft-ietf-ccamp-flexigrid-media-channel-yang

Solved the issue in ccamp-optical-impairment I-D. In this document we will need to provide some overview text on why/how we use OTSi, maybe also include a reference. One requirement may be to co-route bidirectional connection the OTSI.

WDM tunnel is by default co-routed for forward /reverse directions The base TE tunnel has this support for co-routed fwd/rev tunnel.

"bidirectional boolean + "An empty 'route-object-include-exclude' list for a reverse path means it always follows the forward path (i.e., the TE Tunnel is co-routed). When the 'route-object-include-exclude' list is not empty, the reverse path is routed independently of the forward path."

This issue is closed.
