Packet-transmission control method and packet-transmission control apparatus

Abstract

The invention relates to a packet transmission control method for controlling transmission of packets comprising, a storing step of storing an arrival time of a first cell of a frame, a detecting step of detecting a period of time lapsing up to the present time since the arrival time stored at the storing step, a determining step of determining whether or not the frame is to be discarded on the basis of the period of time detected at the detecting step, and a discarding step of discarding the frame in accordance with what is determined by the determining step, and relates to a packet transmission control apparatus for controlling transmission of packets comprising, a storing means for storing an arrival time of a first cell of a frame, a detecting means for detecting a period of time lapsing up to the present time since the arrival time stored by the storing means, a determining means for determining whether or not the frame is to be discarded on the basis of the period of time detected by the detecting means, and a discarding means for discarding the frame in accordance with what is determined by the determining means.
