There are ideas how to mark traffic incapsulated in RDP?

Idea such,

There are policies of prioritization of RDP for operation with the virtual machines (VM). Some users use disk-mapping over RDP for downloading of files from the VM to themselves on the external disk connected to port of the thin client. As soon as the user starts downloading files of large volume, they, naturally, get to a priority flow of RDP, loading all priority channel!

Whether there are any methods of separation similar (incapsulated in RDP) traffics in a separate flow? That is to leave in a RDP flow only 'picture' transmission. And all remaining, incapsulated in RDP (disk-mapping, printer-mapping and other), to select in separate less priority flow.

As an aside, Citrix has internal tags ("visible" to NBAT) so you can tell if the traffic is "screen scraping" vs. disk copying and/or printing, etc.

With RDP, if you have a Cisco device that does per flow policing (e.g. 6500 series) you could treat high usage flows differently.  Otherwise, you might also try looking at the packet's size.  If it's a maximum size packet it might be part of a bulk flow packet train and could be treated differently too.
