PACKET MONITORING METHOD, PACKET MONITORING APPARATUS, AND STORAGE MEDIUM
First Claim
1. A packet monitoring method executed by a packet monitoring apparatus, the packet monitoring method comprising:
- storing acquisition time indicating time when a packet including the transmission source information and the destination information is obtained lastly, and a first counter value into a first memory, in association with a combination of transmission source information and destination information of a plurality of packets;
receiving a first packet;
extracting acquisition time associated with a combination of transmission source information and destination information included in the first packet from the first memory;
determining whether a time period from the extracted acquisition time to acquisition time of the first packet is shorter than a predetermined time; and
increasing the first counter value stored in the first memory and associated with the combination of transmission source information and destination information included in the first packet by a predetermined value when it is determined that the time period is shorter than the predetermined time.
