Quality of Service Assessment
Quality of service (QoS) is the overall performance of a telephony or computer network, 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 error rates, bandwidth, throughput, transmission delay, availability, jitter, cross talk, etc.
As mobile networks are moving to an all-IP model in order to meet the increasing bandwidth requirements and subscriber growth, it is more essential than ever to gain real-time, end-to-end insight into the performance of the network. This insight is necessary to enable effective management of the quality of service throughout the whole network lifecycle. With the introduction of packet networks, key performance metrics are more difficult to demonstrate. Instead of measuring only the transmission, network service providers need to focus more and more on subscriber- and application-based QoS measurements, which enable customer experience management (CEM) and a high quality of experience (QoE).
BT provides an end-to-end quality of service by using a method of coordinating resource allocation between one autonomous system and another.
