摘要： An in-vehicle terminal includes: a communication unit; a necessity determination unit; a basic life determination unit that determines a life of data; a life correction unit that corrects the basic life determined by the basic life determination unit according to factors presumed to affect data fluctuations/data change; and a transmission determination unit that determines a transmission order of the data by the data transmission unit based on (i) the transmission necessity of the data determined by the necessity determination unit and (ii) a post-correction life corrected by the life correction unit, in a manner that (a) data having the higher transmission necessity and/or the shorter post-correction life has an earlier transmission order while (b) data having the lower transmission necessity and/or the longer post-correction life has a later transmission order.

摘要： Disclosed is a technique for controlling communication between a subject device and an external device. The communication is performed via a second network by an application executed by the subject device connected to a first network different from the second network. In the controlling, occurrence of congestion on a communication line used for the communication is detected by monitoring a state of the communication line. Based on the detecting the occurrence of congestion, a notification is transmitted to the application that has used the communication line on which the occurrence of congestion has been detected. The notification indicates congestion on the communication line in use.

摘要： A communication device controls a first communication flow performed by a first terminal and a second communication flow performed by a second terminal. Both of the first communication flow and the second communication flow pass through a sharing section, and the second communication flow has a higher priority than a priority of the first communication flow. The communication device acquires a communication delay in the sharing section; acquires a rated delay of the second communication flow, the rated delay is a communication delay allowed to the second communication flow; and limits input of data from the first communication flow and the second communication flow to the sharing section based on a comparison result between the communication delay of the sharing section and the rated delay.
