| Definition |
Quality of Service (QoS) is a term used to show the requirements of some applications and users are more critical than others, which means that some traffic needs preferential treatment. By using QoS mechanisms, network administrators can use existing resources efficiently and ensure the required level of service without reactively expanding or over-provisioning their networks. Traditionally, the concept of quality in networks meant that all network traffic was treated equally. The result was that all network traffic received the network's best effort, with no guarantees for reliability, delay, variation in delay, or other performance characteristics. With best-effort delivery service, however, a single bandwidth-intensive application can result in poor or unacceptable performance for all applications.

| Context & Usage |
This term is used in software engineering, programming, scripting, testing, application architecture, and development lifecycle work. It helps teams describe how software is designed, implemented, integrated, and maintained.
Operations teams use this concept when setting service expectations, detecting failures, prioritizing traffic, and maintaining reliable communications.
