Title: RPR and WDM topology discovery

I do not think we identifed such a requirement so far, if I understand your question correctly.

Do you mean that a RPR node supports multiple rings on different wavelengths including

bypasses, acting as an interconnection attachment?

 

It would be appreciated if you could clarify more on  

 "will RPR only connect as a client to an existing DWDM network and rely on whatever

  existing transport mechanism is in place?"

In the context of an DWDM RPR implementing optical bypass, would there be a requirement for a dedicated supervisory channel for topology discovery (i.e. if both neighbors of an RPR node add/drop a different wavelength then there is no in-band mechanism for detecting physical adjacencies) - or will RPR only connect as a client to an existing DWDM network and rely on whatever existing transport mechanism is in place ?
