Looking at https://tools.ietf.org/html/draft-ietf-ippm-alt-mark-02 and the marking framework discussed by Giuseppe Fioccola it seems that counting of packets with a given marker label (synonymous label) is a key parameter for the passive measurements. In that case one is interested in both counting packets ingress to the router and egress of a router… It allows understanding of the packets lost in the router fabric (or whatever ‘thing’ is doing the switching)

    Aren’t Synonimous labels significant on egress only?

        For completeness, I was referring to the following work as use case of the RLD info in addition to entropy use-case:

            There is other use case also to do with Synonimous labels and measurements (Alternate marking for passive measurements) potentially….
            Maybe i should add that one also to the use cases.
