Egress network quality of service on Red Hat OpenShift
Network bandwidth is a compressible resource, so setting a flat cap wastes capacity when the link is idle. The real goal is to prioritise production traffic while guaranteeing background workloads a minimum floor, allowing either class to burst to full capacity when the other is idle. The upcoming NetworkQoS CRD in OVN-Kubernetes will bring declarative traffic management, but until then administrators can use Linux traffic control (tc). A hierarchical token bucket (HTB) qdisc tree on the node’s physical interface, with filters matching background traffic by destination IP, provides the desired dynamic prioritisation. In a lab test with 25 Gbps bonded NICs, production traffic maintained 19.5 Gbps under contention while background traffic was throttled to 2.7 Gbps, just above its guaranteed floor.
