Hi, Since most DSCP and QoS functions are normally handled within a single network domain, what impact would it have to manually set precedence at the edge. for example, CE = customer edge, or host systems (TCP endpoints) PE = Provider edge, P = Provider Core, CE - PE - P - PE - CE If the provider PE edge manually sets the precedence outbound to the CE what affect will this have on the TCP session. the TCP RST condition should happen when their is a ["lower precedence" or any change in precedence] if both ends where set to the same precedence by the PE router for example precedence or dscp of "0". Does tcp security have a specific requirement of precedence, what happens if the tcp stack initiates a connection with a precedence of 1 and during transmission it gets reassigned with precedence of "0" does this screw the TCP session/connection? is manually setting precedence or DSCP to the a single value outbound to the CE or TCP endpoints a possible work around?
