Igor,

Traffic type classification is required in any case. Assuming simple case, where traffic class is identified by DSCP, if case separate slice per class, the identification of NSE would be:

Currently defined NSE identification + DSCP

In case of multiple classes per slice, the identification of the NSE would stay the same, and then within the slice DCSP is used for class identification. Similar is already covered int L3SM/L2SM models. And, this is what John added recently as well top the slice draft, in fact.
