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) G/ On 03/03/2017, 23:25, "Jeff Tantsura" <jefftant.ietf@gmail.com> wrote: Aren’t Synonimous labels significant on egress only?
