COMMUNICATION TRAFFIC MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To measure packet communication traffic by a user independently of a packet passage place.SOLUTION: When a measurement start instruction has been received, each communication traffic measuring unit 11a or the like measures communication traffic about IPv6 prefix in the instruction, and has a communication traffic recording table 111 store the IPv6 prefix and the communication traffic. A measurement result collection unit 14 reads out IPv6 prefix and communication traffic from a measurement result file, and has a communication traffic management database 141 store a record including the IPv6 prefix, the communication traffic, and a counting flag indicating that total communication traffic is not calculated. A communication traffic counting unit 15 retrieves a record including the IPv6 prefix and the counting flag indicating that total communication traffic is not calculated per IPv6 prefix from the communication traffic management database 141, calculates the total communication traffic of the communication traffic in all the records, and has a counting result database 151 store the IPv6 prefix and the total communication traffic.
