Hi Joel,

The current version of this draft just describes neccessary PCEP extensions to realize the MPLS source routing based SFC approach as described in (https://tools.ietf.org/html/draft-xu-mpls-service-chaining-00). It doesn't touch the NSH-based SFC approach. I think it's Qin's draft that covers the NSH-based SFC approach.

Best regards,
Xiaohu

Xu, it is unclear in this draft whether your intention is to carry NSH
to support interoperation with other transports and carriage of metadata.

Can you please clarify?

Thank you,
Joel
