Loa,

Thank a lot for the slides, a very good start!
Maybe we just need one layer of PW label, while redefine the MS-PW paradigm to support DetNet data plane.
The T-PEs as defined in the PWE3 can encapsulate/de-capsulate the DetNet frames, and generate the sequence number.
The S-PEs usually can swap the PW label or terminate the PW completely; we can extend their operations to support replication and filtering based on the sequence number.
LSP FECs can work as in the traditional MPLS, but if any new DetNet mechanism is needed in P nodes in the future, we can also add new FECs quite conveniently.

Thanks,
Yuanlong

Subject: [Detnet-dp-dt] a quick look at the replication/discarding case for detnet flows

Folks,

I took a quick look at the replication / discarding case we talked about at the meeting this week.

Please remember that so far this is not a proposal, just a demonstration that there is at least one way of doing it.

What is there can bee revised, improved, changed or discarded if we find something better. Take a look a send comments.
