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. WebTo refresh our memories, congestion can occur anywhere within a network, such as sections of the network that have speed mismatches, aggregations points, or confluences. Queuing algorithms are used to manage congestion. There are … WebWhen packets arrive at a router, they have to be processed and transmitted. A router can only process one packet at a time. If packets arrive faster than the router can process them (such as in a burst transmission) the router puts them into the queue (also called the buffer) until it can get around to transmitting them. cihangir herceg
