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.
