An information generation method includes: obtaining, for respective communication paths included in the communication paths, a write speed of data received through the respective communication paths to a storage device and a reception speed of the data, by a computer; generating first information on a transmission speed of the data for the respective communication paths, based on the write speed and the reception speed; and transmitting the first information to a transmission source device of the data with second information for identifying the respective communication paths.

Information generation method using write speed of data to storage device, information generation device using write speed of data to storage device, and non-transitory recording medium for storing information generation program using write speed of data to storage device

A communication method executed by an information processing apparatus capable of transmitting data of a plurality of sessions to another information processing apparatus, the method includes: acquiring from the another information processing apparatus processing time information according to a time taken for processing a first data received by the another information processing apparatus; calculating an upper limit value of an amount of data per unit time permitted to each of the plurality of sessions for transmission using the processing time information; and limiting the amount of data for each of the plurality of sessions based on the upper limit value calculated at the calculating upon transmitting a second data including data of one or more sessions to the another information processing apparatus.

Communication method, information processing apparatus and recording medium

A storage management apparatus configured to allocate physical addresses in a physical storage area, to virtual addresses in a virtual storage area for storing data is provided. The storage management apparatus includes a processor that executes a process to define, in the physical area, a continuous area having a plurality of continuous physical addresses, and define, based on a virtual address to which a physical address in the continuous area has initially been allocated, an allocation range of virtual addresses for allocating the defined continuous area; and allocate a physical address in the defined continuous area to a virtual address in the defined relation range.

Apparatus and method for allocating virtual memory addresses to continuous physical addresses

A communication method executed by an information processing apparatus capable of transmitting data to another information processing apparatus, the method includes: setting a first threshold as an amount of data capable of being transmitted without waiting for a reply from the another information processing apparatus; transmitting a first data having a data amount less than or equal to the first threshold to the another information processing apparatus; acquiring from the another information processing apparatus processing time information taken to process the first data by the another information processing apparatus; and changing the first threshold concerning the data amount into a second threshold based on the processing time information.

Communication method, information processing apparatus, and recording medium

A communication control system includes a first computer and a second computer, wherein the first computer includes a communication interface device and a first processor configured to control the communication interface device to transmit first data and first feature information indicating a feature of the first data to the second computer, and the second computer includes a memory that has a storage area allocated to store second data received from the first computer, and a second processor configured to determine whether the first feature information received from the first computer matches second feature information, indicating a feature of and calculated based on the second data stored in the storage area, and control the memory to release the storage area when the second feature information does not match the received first feature information.

Communication control system, method, and apparatus

A semi-fixed circuit has a plurality of flip flops connectable in series, a first selector and a second selector, and is capable of operations of a plurality of kinds of scrambler and the like. The first selector selects any one of an exclusive OR signal of an input signal and a first feedback signal, the first feedback signal and the input signal, and outputting the result to a first flip flop. The second selector is capable of selecting an exclusive OR signal of an output signal of a second flip flop and a second feedback signal, an output signal of the second flip flop and the second feedback signal, and outputting the result to the first selector as the first feedback signal.
