Haoyu,

If you consider the NAS as a single entity it is completely consistent with the definition of a stack.  I think this remark is spurious and non-productive.

I propose Network Action Sub-stack Indcator (NSI) for this purpose.  Proposed definition:

                            An LSE used to indicate the presence of a Network Action Sub-stack.

We should also revise the definition of NAS to use this.


Hi Tony,

Stack means “first in last out”. It is used for MPLS label stack to describe the label processing procedure.
The encoded ISD is neither labels any more nor a stack in any sense, so both “sub” and “stack” are improper terms in my opinion. Thanks.

Best regards,
Haoyu
