Abstract—This paper studies the necessary number of simultaneous
TCP connections in a Web client for high Web–QoE.
Currently, many Web browsers use multiple TCP connections
simultaneously for effective data transmission. However, more
simultaneous TCP connections make more establishments/closes
of connections and do not always give higher quality of a Web service
because users often access to the Web services interactively.
Moreover, increase of simultaneous TCP connections causes high
load of a Web server. That is, there exist a necessary number of
simultaneous TCP connections. The authors assess the necessary
number of TCP connections for an online shopping Web service
by experiment; here, they utilizes two psychophysical methods:
the rating scale method and the method of the limit. From
experimental results, they show that the necessary number of
simultaneous TCP connections for high TCP throughput is not
always the same as that for high Web-QoE
