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?
Regards
Phillip.
