network-bandwidth

Limits available bandwidth using Linux tc tbf (token bucket filter).

Target kind: Pod
Implementation: Daemon (ExecNetworkChaos with action: bandwidth)
Rollback: Yes — removes tc tbf rules

Parameters

Name	Type	Required	Default	Description
rate	string	Yes	—	Bandwidth limit (e.g. "1mbit", "500kbit")
burst	string	Yes	—	Burst size (e.g. "10kb", "1mb")
latency	string	Yes	—	Maximum latency before packets are dropped

Example

apiVersion: chaos.chaosplane.io/v1alpha1
kind: ChaosExperiment
metadata:
  name: network-bandwidth-example
  namespace: default
spec:
  target:
    kind: Pod
    namespace: default
    labelSelector:
      matchLabels:
        app: video-encoder
  action:
    type: network-bandwidth
    parameters:
      rate: "1mbit"
      burst: "10kb"
      latency: "100ms"
  duration: 60s
  rollback:
    enabled: true

Rollback behavior

Removes the tc tbf qdisc from the pod's network interface.

Implementation notes

Uses tc qdisc add dev eth0 root tbf rate RATE burst BURST latency LATENCY. All three parameters are required. rate uses tc notation (kbit, mbit, gbit). burst is the maximum amount of data that can be sent at once. latency is the maximum time a packet can sit in the queue before being dropped.
