WebSeries router supports up to eight egress output queues per output port (physical interface). The traditional method of forwarding traffic through a router is based on buffering ingress traffic in input queues on ingress interfaces, forwarding the traffic across the fabric to output queues on egress WebNov 17, 2024 · Queuing Basics When a device, such as a switch or a router, is receiving traffic faster than it can be transmitted, the device attempts to buffer the extra traffic until bandwidth is available. This buffering process is called queuing. You can use queuing mechanisms to influence in what order various traffic types are emptied from the queue.
