Abstract

A network includes first through third communication apparatuses. The second communication apparatus identifies, from packets received from the first communication apparatus, forwarding packets that are packets to be transmitted to the third communication apparatus, and measures the interval in receiving the forwarding packets. The second communication apparatus forwards the forwarding packets to the third communication apparatus. The second communication apparatus receives report information that reports the reception state of forwarding packets from the third communication apparatus, and uses the report information to select target packets that are packets for which success of reception has not been reported from the third communication apparatus in the packets that were forwarded to the third communication apparatus. When the interval in receiving forwarding packets from the first communication apparatus exceeds a threshold, the second communication apparatus retransmits the target packets to the third communication apparatus in a format available for error correction.
