What is Quality of Service?
Quality of service QoS is the description or measurement of the overall performance of a service, such as a telephony or computer network or a cloud computing service, particularly the performance seen by the users of the network. To quantitatively measure quality of service, several related aspects of the network service are often considered, such as packet loss , bit rate , throughput , transmission delay , availability , jitter , etc. In the field of computer networking and other packet-switched telecommunication networks, quality of service refers to traffic prioritization and resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priorities to different applications, users, or data flows , or to guarantee a certain level of performance to a data flow. Quality of service is particularly important for the transport of traffic with special requirements. In particular, developers have introduced Voice over IP technology to allow computer networks to become as useful as telephone networks for audio conversations, as well as supporting new applications with even stricter network performance requirements. In the field of telephony , quality of service was defined by the ITU in

Quality of resilience QoR : NOBEL approach to the multi-service resilience characterization Abstract: With the spread of survivable network the existing quality of service QoS classes are required to be expanded with service availability and maintainability issues. By including them in the service level agreements SLAs new and more complex requirements of commercial applications can be guaranteed.

This document also provides high-level examples showing how to deploy these features in different network environments. Quality of Service for Voice over IP contains the following sections:. For VoIP to be a realistic replacement for standard public switched telephone network PSTN telephony services, customers need to receive the same quality of voice transmission they receive with basic telephone services—meaning consistently high-quality voice transmissions. Like other real-time applications, VoIP is extremely bandwidth- and delay-sensitive. For VoIP transmissions to be intelligible to the receiver, voice packets should not be dropped, excessively delayed, or suffer varying delay otherwise known as jitter.
