The Measurement of Users Subjective Assessment on Throughput Degradation in Bulk Data Transmission
Recent studies have focused on subjective assessment of a user,which assessment is referred as user-level QoS.The subjective assessment means a qualitative evaluation of a user.However,previous works have studied users subjective assessment only in real-time traffic.Moreover,an absolute assessment has been performed in the subjective assessment of a user.Considering degradation of quality of network services,it is important how a user feels about degradation of the QoS in the usual network environment.In this paper,we measure users subjective assessment in degradation of communication quality in bulk data transmission.To obtain the users subjective assessment,we adopt the constant method and the method of successive categories.From results of the experiment,we clarify how much throughput degradation compared with the usual network environment makes a user be felt dissatisfaction with.
