I appreciate the small and well specified format of t= he measurement and hope that endpoints and transit routers supporting Path = Tracing in SRv6 networks are able to fill in the specified fields at linera= te during forwarding. I'd also appreciate an SR-MPLS version of the draft. I'd suggest to add more text related to the following statement: Note: all routers across the network MUST have time- synchronization. The mechanism used for time synchronization is out of the scope of this draft. An operator should be able to qualify an applicable time-synchronisation by= guidance of the draft. If Truncated Timestamp configuration depends on the= precision of time synchronization, guidance for interested operators shoul= d be part of the draft. The choice of timestamp resolution may further depe= nd on locally configured buffers. A Truncated Timestamp working well in the= absence of congestion, but creating erroneous information with the onset o= f congestion might not be desired. Maybe a discussion on wrapping / overflo= w may help too. Finally, the precision of the synchronization needs to be m= onitored. That may be done out of band, but centralized processing should = be aware of timestamps created by a router with (temporarily) bad synch. A = temporal change in precision of or a loss of synch are common networking s= ynch-events. While the mechanism used for time synchronization doesn't need to be define= d in the draft, a reference to some applicable synchronization mechanisms w= ould be helpful. The list doesn't have to be complete, please add some comm= odity examples. Editorial nit: To me, a binding "Requirement" shouldn't be a "Note".
