The current implementation of PIE queueing discipline is according to an IETF draft [http://tools.ietf.org/html/draft-pan-aqm-pie-00] and the paper [PIE: A Lightweight Control Scheme to Address the Bufferbloat Problem]. However, a lot of necessary modifications and enhancements have been proposed in RFC 8033, which have not yet been incorporated in the source code of Linux kernel. The following series of patches helps in achieving the same.
This patch series includes: 1. Change the value of QUEUE_THRESHOLD 2. Change the default value of pie_params->target 3. Change the default value of pie_params->tupdate 4. Change the initial value of pie_vars->burst_time 5. Add more conditions to auto-tune alpha and beta 6. Add mechanism to set PIE active/inactive 7. Add a derandomization mechanism 8.
