Does router inside MT takes care about DSCP flags?

Does MT router takes care about DSCP flags in packet header, are packets processed in different way regarding its priority (first three bits) and/or its bits for reliability / throughput / low delay? Or these bits are only transported together with packet and makes no sense inside MT network?
As I understand, DSCP bits were introduced to distinguish several types of service to be packets processed individually through network, that “clever” routers will use this function “in the future”.

I know about DSCP based QoS system published on wiki (setting different DSCP values for different kinds of traffic and then packet marking and queueing). Ie. can I use whatever DSCP values for my QoS system without any problems?

Any kind of router only will take care about dscp / priority flags , if the network administrator , make the rules for what the router will do when marked packets arrives. So in router OS you should tell him what to do with these kind of packets.

IE: , if a packet with the dscp 46 arrives and there are no rules in the router, nothing will happen, but if the router have some rule ( mangle, queue tree, ) that will get these packet and do the priority thing !

thanks, it was important for me to understand if it is router “hw feature” or tool for router admins …
