Hi Loa,

For the PW scenario the Control Word is envisioned to provide sequencing services, 
and so the CW would be mandatory for DetNet flows.

We have identified one issue with the CW, namely the size of the sequence number 
in a generic CW is 16 bits. Depending on the link and the DetNet flow speed it may 
be too little.

Cheers
Bala'zs

Subject: [Detnet-dp-dt] where do I find the sequence number

Folks,

I'm thinking about the discussion we had last meeting, to avoid silly mistakes, one question.

In the case we have the detnet PW running over MPLS, where do we place the sequence number.

Is it part of the PW payload?
