Statement:
6TiCH use case: Read energy data from devices (app layer?) - Extensible protocol - vendor specific?
Discussion:
The relevant text in the draft is as follows:

The PCE should be able to read energy data from devices, and compute paths that will implement policies on how energy in devices is consumed, for instance to ensure that the spent energy does not exceeded the available energy over a period of time.

Please excuse my naivete with respect to PCE's but to me this sounds like the PCE (which is nominally an application) is expected to support a vendor-extensible protocol to enable arbitrary information to be queried from/pushed to devices, and also some kind of vendor-supplied "plug-in" to the "path computation" algorithm so that such information can be incorporated into the resulting path computation. Is this within scope of DetNet? Perhaps a "DetNet 2.0" feature or is it critical to build this into the initial design, or account for it in any way?
