Modern websites consist of many rich objects dynamically produced by servers and client terminals at diverse locations. Consequently, we face complications in understanding the communication structure generated when accessing websites. To reduce the response time at browsed websites, many objects of websites are delivered using content delivery networks (CDNs), in which data objects are delivered from cache servers located close to user terminals. Although the web response time has been expected to be reduced by using CDNs, the actual effect of CDNs on the reduction of web response time depends on the geographical deployment of website objects. However, no works have investigated the tendency of geographical deployment of website objects. In this paper, to answer this fundamental question, we measure the communication structure of traffic generated when accessing about the 1,000 most popular websites from 12 locations in the world, and we obtain various findings. For example, it will be desirable to give high priority to entertainment websites at nighttime, whereas give high priority to business-related websites at daytime. |
