Hi Loa and WG,

I agree with the statements. But we should have use cases before mechanisms and not vice versa. 

Best regards,
Haoyu

Subject: [mpls] Poll 1: ISD and PSD in the MNA Framework

MPLS working group and and the Open MPLS DT,

The working group chairs believe the current situation is:

The Framework document must be solution independent and say:

a packet may carry Ancillary Data using one or both of the following
methods:

    (1) in-stack, and

    (2) post-stack.

It is up to the document specifying the Network Action to specify which method is to be used for which Ancillary Data.

Note, a Network Action may not require inclusion of Ancillary Data.

Is this the consensus of the working group? Please respond to the MPLS WG mail list.


Loa Andersson
for the Open DT wg chairs
