In [[telecommunications]] and [[computer engineering]], the '''queuing delay''' is the time a job waits in a [[Queue (data structure)|queue]] until it can be executed. It is a key component of [[network delay]]. 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. <ref name=Gov>{{cite web|title=Queuing Delay|url=http://www.its.bldrdoc.gov/fs-1037/dir-029/_4318.htm|access-date=2012-02-12|archive-url=https://web.archive.org/web/20121219004715/http://www.its.bldrdoc.gov/fs-1037/dir-029/_4318.htm|archive-date=2012-12-19|url-status=dead}}</ref>
