NETWORK BOOT SYSTEM, NETWORK BOOT METHOD, AND CACHING DEVICE FOR NETWORK BOOT

摘要

PROBLEM TO BE SOLVED: To provide a network boot system capable of shortening the time required to start a diskless personal computer (PC) having no storage devices. SOLUTION: When data for a transmission request from a diskless PC 1 is a request for reading a prescribed logical block, for example, logical block address 0, a cache device 2 transmits a request for reading logical block address 0 to a storage router 7 and transmits a request for reading preliminarily set OS image-portion data to the storage router 7. The cache device 2 stores a received OS image in an incorporated storage medium in response to receiving a read response of OS image-portion data from the storage router 7 and thereafter transfers pertinent data to the diskless PC 1 from the OS image stored in the device itself without requesting read to a storage device 6, in response to a read request for logical block address 1 and following addresses from the diskless PC 1.
