31.2.2 TRTCM-Color-aware Mode
In
Packets marked red (high packet loss priority) continue to be red without evaluation against the PIR or CIR. Packets marked yellow can only be marked red or remain yellow so they are only evaluated against the PIR. Only the packets marked green are first evaluated against the PIR and then if they don’t exceed the PIR level are they evaluated against the CIR.
