Hi, I am trying to understand the implementation of Random Early Detection (RED) AQM in DPDK. I have read the dpdk/lib/librte_sched/rte_red.c and rte_red.h files but i don't understand the implementation. Please help me to understand the following questions. 1. How RED parameters are configured? 2. What is *wq_log2*, *maxp_inv* and How their default values are determined? (original terms in RED paper are wq and maxp) 3. What is *uint16_t rte_red_log2_1_minus_Wq[RTE_RED_WQ_LOG2_NUM]* and *uint16_t rte_red_pow2_frac_inv[16]* and how the size of these arrays is determined? 4. I found that wq is calculated using lookup tables, how this is actually implemented? Thanks in advance! Thanks, Gokul
