Re: [PWE3] draft-bryant-filsfils-fat-pw-03 to WG draft?

stewart:
  it is not clear _expression_ here
to use service header . IMO, adding flow ID following CW field to identify
which flow the service data will belong to? then the service data may be
carried by ECMP to another sink points, the sink points will identify the
service data by flow ID . and the packet formats will the following:

          LSP Label

          PW Label

           CW

          Flow ID    

          Service data

   in addtions. if using a
flow label, I think the draft will be MPLS or MPLS-TP draft and shouldn't
be disscussed in pwe3 work group. 
thank you.

What do you mean by the services header?

Please can you sketch out your label stack and describe the operations
you have in mind?

Thanks
