Packet Capture System, Method and Program - A simplified explanation of the abstract
This abstract first appeared for US patent application 18254101 titled 'Packet Capture System, Method and Program
Simplified Explanation
The abstract describes a packet capture system that captures packets in a network. It consists of multiple stages of packet distribution devices that capture packets of a specific flow. These devices analyze inputted packets to identify the flow to be captured.
- The packet distribution devices are cascade-connected, meaning they are connected in a series.
- Each device distributes packets to capture the desired flow and passes on packets of other flows to the next device.
- The last-stage device filters and discards packets that do not belong to the flow to be captured.
Potential applications of this technology:
- Network monitoring and analysis: The system can be used to capture and analyze packets for troubleshooting network issues or monitoring network performance.
- Security analysis: By capturing packets of specific flows, the system can aid in detecting and analyzing potential security threats or attacks.
- Quality of Service (QoS) management: The system can help monitor and manage network traffic to ensure optimal QoS for specific flows.
Problems solved by this technology:
- Efficient packet capture: The cascade-connected packet distribution devices allow for targeted capture of specific flows, reducing the amount of unnecessary data captured.
- Flow identification: The devices analyze packets to identify the flow to be captured, ensuring accurate capture of the desired data.
- Packet filtering: The last-stage device filters out packets that do not belong to the flow to be captured, reducing the processing and storage requirements.
Benefits of this technology:
- Improved network analysis: By capturing only the packets of interest, the system reduces the amount of data to be analyzed, making network analysis more efficient.
- Enhanced security monitoring: The ability to capture packets of specific flows aids in detecting and analyzing potential security threats, improving network security.
- Resource optimization: The targeted capture and filtering of packets reduce the processing and storage requirements, optimizing resource utilization.
Original Abstract Submitted
A packet capture system for capturing packets flowing in a capture target network, and a plurality of stages of packet distribution devices for capturing packet of a specific flow are cascade-connected, packet distribution devices identify a capture target flow by analyzing inputted packets, packet distribution devices other than a last-stage packet distribution device are configured to distribute packets to capture packets of a flow to be captured and output packets of a flow not to be captured to a next-stage packet distribution device, and the last-stage packet distribution device is configured to filter the packets of the flow to be captured and to discard the packets of the flow not to be captured.
