This paper evaluates the access quality of the Internet WWW service. First, access times to various home-pages on the Internet were evaluated through the campus LAN and a dial-up modem-circuit to NTT OCN. Next, various performance parameters of an IP-network, which affect the access times to the home-pages, were evaluated to clarify the relation between the access times and the performance parameters of the IP-network. Based on these evaluation results, it was confirmed that access quality of a WWW home-page is mainly effected by the congestion of the back-bone network for the LAN-connection and the dial-up OCN connection. Furthermore, it is proposed as an evaluation method of IP-network performance to measure the round-trip time of an IP-network and extract a bottle-neck of the network by using the "tracert" and "ping" commands. The access quality can be estimated by the circuit occupation ratio of the bottle-neck network. This paper also presents the evaluation results of the subjective quality of the access times. The results show that access time of up to 30 seconds may be acceptable. Through this study, areas requiring further study are identified; these include evaluating other advanced home-pages such as an audio-visual one and developing precise evaluation methods of IP-network performance parameters.
