MESSAGE REPEATING METHOD, MESSAGE PROCESSING METHOD, ROUTER DEVICE, NETWORK SYSTEM AND STORAGE MEDIUM STORING PROGRAM CONTROLLING ROUTER DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce a network load and to shorten the booting time of a net work computer by providing a cache function at a router device and transmit ting data on a cache to a terminal-side instead of a server. SOLUTION: When a reception packet is judged to be a cache object based on a transfer request management table 204, it is judged whether the packet is cached or not based on the cache management table 216. When it is cached, a substitute transfer control part 205 generates a data transmission packet following a transfer protocol, rewrites header information into the value of source IP address of the transfer request packet and transmits it to the data terminal-side. When it is not cached, the update processing of the transfer request management table 204 is executed and the packet is transmitted to a high-order network 231. When the reception packet is not the cache object, it is transmitted to the high-order network 231 as it is.
