PFIFO and BFIFO are MikroTik RouterOS queue management strategies following FIFO principles, with PFIFO prioritizing packets by arrival order and BFIFO managing byte-based bandwidth allocation. Both ensure fairness but lack traffic prioritization, differing in queue size measurement and packet dropping behavior.
Queue types in MikroTik RouterOS define queuing disciplines for managing packet flow, with options like BFIFO and PFIFO offering basic FIFO behavior, while advanced types such as CAKE and FQ_CoDel provide latency control and fair bandwidth distribution. Selection depends on network priorities like simplicity, fairness, or congestion management.
