Title:
PACKET FLOW MONITORING DEVICE, PACKET DATA EXTRACTION DEVICE, EXTRACTED DATA AGGREGATING DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/095692
Kind Code:
A1
Abstract:
[Problem] To provide a packet flow monitoring device, a packet data extraction device, an extracted data aggregating device, and a program for efficiently and highly accurately monitoring a packet flow in a video or audio communication system constructed with an Ethernet (registered trademark) frame or IP packet network. [Solution] This packet flow monitoring device 1 comprises: a packet data extraction device 2 for replicating all of passed packets that have passed through one or a plurality of specific network switches on the network, extracting predetermined partial information in each of the replicated passed packets, and configuring and outputting an aggregated extracted data report packet; and an extracted data aggregating device 3 for receiving the extracted data report packet, analyzing the partial information in each of the replicated passed packets included in the extracted data report packet so as to aggregate for each packet flow, and recording the result as aggregate data.
