Starting with 4.11 a cluster administrator can tag pod egress traffic with some QoS DSCP value:

Capturing this value would make new filter possible.

Ex: "As a cluster admin, I want to see all high priority traffic"

There have been work from other teams to use DSCP and QoS, exposing this field is interesting.

Work that needs to be done:

• capture this field from IP header (ebpf-agent). The ip header is already parsed
• add new field to FLP protobuf
• expose this field & filter in the console plugin

Why is this important?

Differentiated Services Code Point (DSCP) is a means of classifying and managing network traffic and of providing quality of service (QoS) in modern Layer 3 IP networks. It uses the 6-bit Differentiated Services (DS) field in the IP header for the purpose of packet classification.
