# sfunnel: multi-flow k8s pod session affinity | ||
|
||
`sfunnel` is an [eBPF](https://ebpf.io/)-based tool to [_funnel_](#funneling) | ||
multiple flows through a single [K8s service](https://kubernetes.io/docs/concepts/services-networking/service/) | ||
(e.g. LoadBalancer) 'port', to ensure `ClientIP` affinity is consistent for | ||
all 'ports' in the service. | ||
|
||
Think about it as a _congruent_ `sessionAffinity: ClientIP` for all | ||
ports of a K8s service under certain conditions. | ||
|
||
See the original use-case [here](docs/use-cases/network-telemetry-nfacctd.md). | ||
