Transmission system, transmission device, and transmission method

A network includes first through third communication apparatuses. The second communication apparatus identifies, from packets received from the first communication apparatus, forwarding packets that are packets to be transmitted to the third communication apparatus, and measures the interval in receiving the forwarding packets. The second communication apparatus forwards the forwarding packets to the third communication apparatus. The second communication apparatus receives report information that reports the reception state of forwarding packets from the third communication apparatus, and uses the report information to select target packets that are packets for which success of reception has not been reported from the third communication apparatus in the packets that were forwarded to the third communication apparatus. When the interval in receiving forwarding packets from the first communication apparatus exceeds a threshold, the second communication apparatus retransmits the target packets to the third communication apparatus in a format available for error correction.

An image transmitting method is used to transmit image data from an image transmitting apparatus to an image receiving apparatus. The image transmitting device receives operation events generated in the image receiving device through a network. The image transmitting apparatus calculates a determination time of the image data, in a transmission control based on a previously determined transmission interval, based on an amount of the image data to be transmitted to the image receiving apparatus, information regarding the network through which the image data is transmitted, and a number of the operation events that have been received from an immediately previous transmission time until a time of transmitting the image data. The image transmitting apparatus compares the determination time with a transmission time indicating a time of transmitting the image data, and prevents a transmission of the image data when the determination time is later than the transmission time.

An execution history tracing method includes tracing an execution history of a CPU upon executing, in a semiconductor device including the CPU, a program by using the CPU, for one or a tracing target, from outside the semiconductor device via software. The execution history tracing method includes recording, in a buffer, target information as trace information about an execution of the one or the tracing target, for each instruction cycle in which the target information is produced as the execution history; and performing data sorting by using the software to group the trace information about the execution of the one or the tracing target, the trace information being recorded for the each instruction execution cycle, for each of the one or the tracing target.

A transfer device allocates, within the range of the maximum communication band of a network that a plurality of groups of applications use in common, a communication band equal to or larger than the minimum band for each of the groups. Furthermore, the transfer device converts, within a communication band allocated to each group, TCP data received from a transmission source of data to UDP data, transfers the UDP data to a transmission destination, and retransmits retransmission data in response to a retransmission request of the UDP data.

Transfer device, and transfer method

A transfer device increments a value of a phase ID at predetermined time intervals, and registers a packet ID of a transmitted data packet and a phase ID on a determination table in an associated manner. When having received a response packet from a receiving-side transfer device, the transfer device determines an unarrived packet on the basis of received packet IDs contained in the received response packet and packet IDs of transmitted data packets. Then, the transfer device determines whether a data packet corresponding to the unarrived packet is lost or on-the-fly from a relationship between a phase ID of the unarrived packet and the maximum phase contained in the received response packet, and retransmits the corresponding data packet only if it is lost.

A prior simulation of a velocity field and a temperature field is carried out, and snapshot data of the velocity field and that of the temperature field are collected during the prior simulation. Then principal component analysis on the collected snapshot data obtains velocity-field and temperature field dimension transformation matrixes, on the based on which the analysis models of the velocity field and temperature field having respective first degrees of freedom are converted into reduced degree-of-freedom models. Consequently, a simulation of the velocity field and the temperature field is carried out using models having respective reduced degrees of freedom (i.e., second degrees of freedom).
