network-delay

Adds artificial latency to all outbound packets from the targeted pods using Linux tc netem.

Target kind: Pod
Implementation: Daemon (ExecNetworkChaos with action: delay)
Rollback: Yes — removes tc netem rules from the pod's network namespace

Parameters

Name	Type	Required	Default	Description
latency	string	Yes	—	Base latency to add (e.g. "100ms", "1s")
jitter	string	No	"0ms"	Random jitter range
correlation	string	No	"0"	Correlation between successive delays (0-100)

Example

apiVersion: chaos.chaosplane.io/v1alpha1
kind: ChaosExperiment
metadata:
  name: network-delay-example
  namespace: default
spec:
  target:
    kind: Pod
    namespace: default
    labelSelector:
      matchLabels:
        app: frontend
  action:
    type: network-delay
    parameters:
      latency: "200ms"
      jitter: "50ms"
      correlation: "25"
  duration: 60s
  rollback:
    enabled: true

Rollback behavior

Removes the tc netem qdisc from the pod's network interface. Traffic returns to normal immediately.

Implementation notes

Uses tc qdisc add dev eth0 root netem delay LATENCY JITTER CORRELATION% in the pod's network namespace. The latency parameter is required. Correlation makes consecutive packet delays correlated (realistic for real network conditions).
