Relay apparatus, reception apparatus, and communication system

摘要

A relay apparatus in a communication system including a transmission apparatus, a reception apparatus, and a plurality of relay apparatuses which include the relay apparatus, including: a receiver receiving distributed sequential packets from the transmission apparatus which distributes sequential packets for the reception apparatus among the plurality of relay apparatuses, a memory storing distributed sequential packets of the sequential packets in sequential order, the distributed sequential packets are distributed and transmitted to the relay apparatus by the transmission apparatus, and a processor selecting a discard packet from the distributed sequential packets based on a discard condition, and to add a discard information to a previous packet and to transmit the previous packet, the discard information indicates a sequence number of the discard packet to be discarded, and the previous packet is one of the distributed sequential packets before the discard packet in sequential order.
