Network system and communication log analyzer

A network system comprising:

• a plurality of communication units, wherein the plurality of communication units include a terminal, a base station that wirelessly connects to the terminal, and a proxy server that is connected to a network when the terminal connects to a WEB server;
• a communication log analyzer configured to connect the plurality of communication units via the network, and
• means for setting a path to bypass traffic to the terminal in accordance with a traffic volume between the base station and the WEB server, wherein:
• the plurality of communication units generate communication log information, and transmit the generated communication log information to the communication log analyzer, and
• the communication log analyzer is configured to:
• extract communication log information of communication between the base station and the terminal from the communication log information received from the base station,
• obtain a connection location or a travel route of the terminal based on the communication log information between the base station and the terminal,
• extract communication log information including information of the WEB server from the communication log information received from the proxy server,
• estimate at least one of the travel route and a travel method from at least one of route information, travel speed, and travel direction, the route information including information on routes within each of transmission ranges of the respective base stations, and
• associate the communication log information including the information of the WEB server with the travel route and the travel method.
