Term Definition

In the field of computer networking and other packet-switched telecommunication networks, the traffic engineering term Quality of Service or QoS describes resource reservation controls rather than the resulting service quality. QoS is a cability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. For example, a required bit rate, delay, jitter, packet dropping probability and/or bit error rate may be guaranteed. Quality of service guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications such as voice over IP, online games and IP-TV, since these are delay sensitive, and in networks where the capacity is a limited resource.
