Router, Endgerät, Kommunikationssytem und Routing-verfahren

摘要

A router includes a clock configured to be synchronous to a transmission terminal that transmits a data packet; a comparator configured to compare a delay time of the data packet with an acceptable delay time of the data packet based on the time obtained from the clock; and a packet processing unit configured to either transfer or discard the data packet based on the comparison result of the comparator.
