Hi Lucy,

You suggest in section 5 re-defining the three TC bits in the flow label. The FAT-PW draft defined the new flow label in the label stack and mentioned in its section 7.1. "... that the semantics of a label stack entry (LSE) as defined by [RFC3032] cannot be modified ..."

Is it worthwhile to discuss with the FAT-PW authors about re-defining the TC bits in flow label as "reserved for per flow characteristics" in the FAT-PW draft?
