Re: BCP regarding TOS transparancy for internet traffic

Overwriting the tos flags is not "best effort", it is "degraded service"

So how do you propose to control the use of TOS flags within a network? If I have an application that receives specific treatment because of its TOS flags, I need to prevent non-compliant traffic from using this TOS flag at other ingress points. This requires either dropping that traffic or rewriting the flag.
