[Starlingx-discuss] How low latency implemented in STX?

[Jones, Bruce E]

There are several low latency features in StarlingX, depending on what you mean by low latency.

StarlingX supports the rt-linux kernel, which significantly improves kernel scheduling and reduces rt application latency.

It also supports OVS DPDK, which greatly reduces network packet delivery latency, which I believe is only supported today in Neutron.  There is work in progress in the community to enable DPDK in Kubernetes but AFAIK that work has not yet been picked up by StarlingX.

Hi,


I would like to know how low latency implemented in StarlingX.
- Is it implemented only in starlingx itself
or
Is it implemented in Kubernetes shipped with starlingx?
Any optimization has been done to Neutron (under OpenStack) in order to achieve low latency with virtualized networking?
or do we use exact same upstream OpenStack components under StarlingX?

Regards,
Danishka
