Subject: RE: [dpdk-dev] [PATCH v9 0/8] Enable dynamic config of subport
bandwidth
09/10/2020 14:39, Savinay Dharmappa:
> DPDK sched library allows runtime configuration of the pipe profiles
> to the pipes of the subport once scheduler hierarchy is constructed.
> However, to change the subport level bandwidth, existing hierarchy
> needs to be dismantled and whole process of building hierarchy under
> subport nodes needs to be repeated which might result in router
> downtime. Furthermore, due to lack of dynamic configuration of the
> subport bandwidth profile configuration (shaper and Traffic class
> rates), the user application is unable to dynamically re-distribute
> the excess-bandwidth of one subport among other subports in the
> scheduler hierarchy. Therefore, it is also not possible to adjust the
> subport bandwidth profile in sync with dynamic changes in pipe
> profiles of subscribers who want to consume higher bandwidth
> opportunistically.

> This patch series implements dynamic configuration of the subport

> re-distribution is needed the without making any structural changes in the

> The implementation work includes refactoring the existing api and data

I was asking a question in my reply to v8 but you didn't hit the "reply" button.

One more question: why don't you keep the ack given by Cristian in v7?

Hi Thomas,
Could you please let me know regarding resending the patch ?
