COMMUNICATION METHOD AND COMMUNICATION APPARATUS
First Claim
1. A communication method, in a network including a first communication apparatus, a second communication apparatus, and a third communication apparatus, executed by the second communication apparatus, comprising:
- identifying, from packets received from the first communication apparatus, forwarding packets that are packets to be forwarded to the third communication apparatus;
measuring an interval in receiving the forwarding packets from the first communication apparatus;
forwarding the forwarding packets to the third communication apparatus;
receiving report information that reports a reception state of the forwarding packets from the third communication apparatus;
using 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; and
when the interval in receiving the forwarding packets from the first communication apparatus exceeds a threshold, retransmitting the target packets to the third communication apparatus in a format available for error correction.

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.

5. A communication apparatus comprising:
-
a receiver configured to receive packets from a terminal; and a processor configured to perform a process including measuring an interval in receiving forwarding packets that are packets forwarded to a communication destination of the terminal, forwarding the forwarding packets to the communication destination, selecting target packets that are packets for which success of reception has not been reported from the communication destination in the packets that were forwarded to the communication destination, and performing, when the interval in reception of the forwarding packets exceeds the threshold, a process for retransmitting the target packets to the communication destination in a format available for error correction. - View Dependent Claims (7)

8. A computer-readable recording medium having stored therein a program for, in a network including a first communication apparatus, a second communication apparatus, and a third communication apparatus, causing the second communication apparatus to execute a process comprising:
-
identifying, from packets received from the first communication apparatus, forwarding packets that are packets to be forwarded to the third communication apparatus; measuring an interval in receiving the forwarding packets from the first communication apparatus; forwarding the forwarding packets to the third communication apparatus; receiving report information that reports a reception state of the forwarding packets from the third communication apparatus; using 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; and when the interval in receiving the forwarding packets from the first communication apparatus exceeds a threshold, retransmitting the target packets to the third communication apparatus in a format available for error correction. - View Dependent Claims (9, 10, 11)
