> Subject: [PATCH v15 0/5] Add PIE support for HQoS library
>
> DPDK sched library is equipped with mechanism that secures it from the
> bufferbloat problem
> which is a situation when excess buffers in the network cause high latency
> and latency
> variation. Currently, it supports RED for active queue management.
> However, more
> advanced queue management is required to address this problem and
> provide desirable
> quality of service to users.
>
> This solution (RFC) proposes usage of new algorithm called "PIE"
> (Proportional Integral
> controller Enhanced) that can effectively and directly control queuing latency
> to address
> the bufferbloat problem.
>
> The implementation of mentioned functionality includes modification of
> existing and
> adding a new set of data structures to the library, adding PIE related APIs.
> This affects structures in public API/ABI. That is why deprecation notice is
> going
> to be prepared and sent.
