Title:
CONTENTS TRANSFER METHOD AND NETWORK SYSTEM, AND MACHINE-READABLE RECORDING MEDIUM WITH PROGRAM RECORDED THEREIN
Document Type and Number:
Japanese Patent JP3674471
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a contents transfer method by which contents having no urgency such as contents looked ahead by a cache server are transferred without giving much effect on other traffic.
SOLUTION: In the case of looking ahead newest contents that may be accessed from terminal T1 with high possibility, a relay control cache server C1 allows a Web server S1 storing the contents to transfer the contents to a relay server M2 and allows the relay server M2 to transfer the contents to a relay server M1, and finally allows the relay server M1 to transfer the contents to the relay control cache server C1. Since the band consumption at a point of time can be decreased in comparison with the case of directly transferring the contents from the Web server S1 to the relay control cache server C1, the effect given on other traffic can be reduced.
