Hi Aijun,
Thanks for the support.
Regarding your question, I think we can clarify this point in the next version. If a PCE instantiates a path on the PCC with an IFIT capability enabled, it is supposed that there are at least two nodes (e.g. starting and ending node) which support it. But if nodes on the path do not support some capabilities, it is not a big issue. Indeed, both Alternate Marking and IOAM documents specify that nodes that do not support a specific functionality will forward the packet without any changes to the data fields and they are simply not considered in the measurement.

Regards,

Giuseppe

Hi, All:

I support its adoption.

One questions to the authors:
Is it enough that only the headend support the defined iFIT capabilities? What’s the procedures when the nodes on the LSP/SR path doesn’t support the defined iFIT capabilities?
