Queuing delay

<p>In <a href="/facts/Telecommunications/vxoj1cxR">telecommunications</a> and <a href="/facts/Computer_engineering/5x1TRKGo">computer engineering</a>, the queuing delay is the time a job waits in a <a href="/facts/Queue_(data_structure)/hVPjPXus">queue</a> until it can be executed. It is a key component of <a href="/facts/Network_delay/JK7jmoJu">network delay</a>. In a switched network, queuing delay is the time between the completion of signaling by the call originator and the arrival of a ringing signal at the call receiver. Queuing delay may be caused by delays at the originating switch, intermediate switches, or the call receiver servicing switch. In a data network, queuing delay is the sum of the delays between the request for service and the establishment of a circuit to the called data terminal equipment (DTE). In a packet-switched network, queuing delay is the sum of the delays encountered by a packet between the time of insertion into the network and the time of delivery to the address.
