Title:   SG15 opinion on draft-manhoudt-pwe3-tsop-01.txt
Body:

Please find attached draft-manhoudt-pwe3-tsop-01.txt (Transparent SDH/SONET over Packet). This is an individual draft submitted to the PWE3 working group to propose a new structure-agnostic pseudowire encapsulation for SONET/SDH client signals, as opposed to RFC 4842 (SONET/SDH Circuit Emulation over Packet), which is structure-aware. There is currently no clear consensus in the WG regarding the technical approach presented in this draft, and to aid the WG in its decision whether to progress with this work, we would very much appreciate SG15's opinion regarding the correctness of the draft's technical approach, its suitability for standardization in the IETF, and whether it unnecessarily duplicates the functionality of RFC 4842.

Best regards,
