摘要

PROBLEM TO BE SOLVED: To provide a method and a system capable of obtaining a trustworthy evaluation result for a bandwidth which a client can acquire.;SOLUTION: A method, a program, and a server for evaluating a bandwidth of network connection between a client and the server comprises a request to the server for continuously supplying a first and a second objects to the client from the server. The first and the second objects are transmitted to the client. The client determines a time interval between distribution of the first and the second objects. The time interval is used together with an information about the size of the second object to evaluate the bandwidth. The first and the second objects are transmitted from a content distribution network server close to the ISP (Internet Service Provider) of the client in architecture so as to improve reliability of bandwidth evaluation.;COPYRIGHT: (C)2006,JPO&NCIPI
