Abstract: 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.

Abstract: 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.
