Understanding Color-Blind Mode for Two-Rate Tricolor Marking
With the color-blind mode of two-rate tricolor marking, all packets are evaluated against the committed information rate (CIR). If a packet exceeds the CIR, it is evaluated against the peak information rate (PIR). Packets that exceed the CIR but are below the PIR are marked yellow (medium-high). Packets that exceed the PIR are marked red (high).
Table 1: Color-Blind Mode TCM Color-to-PLP Mapping
Color | PLP | Meaning |
|---|---|---|
Green | low | Packet does not exceed the CIR. |
Yellow | medium-high | Packet exceeds the CIR but does not exceed the PIR. |
Red | high | Packet exceeds the PIR. |
