  • Patent number: 8250110
    Abstract: A proxy server 10 transfers, when a protocol header and content specified in a distribution request from a client 18 are not stored in a storage device 28, the distribution request to an origin server 12; stores the protocol header and content, which have been transmitted from the origin server 12, in the storage device 28; transmits the protocol header and content to the client 18; creates another protocol header based on the protocol header transmitted from the origin server 12; and stores the created protocol header in the storage device 28. When the protocol header and content specified in the distribution request from the client 18 have been stored in the storage device 28, the proxy server 10 extracts the protocol header and content from the storage device 28 and distributes them to the client 18.

  • Patent number: 8151275
    Abstract: A method and an apparatus for storing a copy of memory-mapped I/O (MMIO) register are provided for enhancing data processing efficiency. In a structure in which data processing is executed by associating a plurality of logical processors with a physical processor by timing sharing, a host OS stores copy information, namely, shadow, of the MMIO register corresponding to a logical processor in memory both in an active state where a physical processor is allocated to a logical processor corresponding to a guest OS and in an inactive state where no physical processor is allocated to a logical processor. This structure enables a guest OS to gain faster access to the MMIO register through the shadow by memory access, instead of a direct access to the MMIO register, so as to achieve efficient data processing.
