FIFO Queueing

First-in, first-out queuing (FIFO queuing) is an algorithm in switching and routing that involves buffering and forwarding of packets in the order of arrival. FIFO embodies no concept of priority or classes of traffic. There is only one queue, and all packets are treated equally. Packets are sent out an interface in the order in which they arrive.
