Question 13

​Quality of experience (QoE), quality of service (QoS) and performance requirements and assessment methods for multimedia

(Continuation of Question 13/12 - QoE, QoS and performance requirements and assessment methods for multimedia)

Motivation
A major challenge for emerging IP-based networks is to provide adequate Quality of Experience (QoE) and Quality of Service (QoS) for new multimedia services and applications. An example is web-based applications, including so-called cloud-based applications such as on-line gaming. Another example is DFS (digital financial services). In such applications, QoE is affected not only by network QoS, but also by server and terminal performance. These services are inherently multi-media, incorporating audio, video, text, graphics, and interactive control functions, and performance requirements and associated measurement methodologies for each of these aspects need to be defined.
