Problems solved by technology
[0004] The existing network packet loss ratio estimation technology is based on the capture process. After the network packet is captured through a professional network card, the lost network packet is counted, calculated and reported during the process of writing the data to the hard disk or memory. The packet loss ratio of network packets does not consider the packet loss caused by the mirror copy process, and does not calculate the packet loss ratio of network packets in this process, resulting in low accuracy of the packet loss ratio estimated by the existing network packet loss ratio estimation technology , leading to inaccurate data analysis

The embodiment of the present invention discloses a method and device for estimating the packet loss ratio of a network packet capturing process. The method includes: extracting the TCP packets in the captured and port mirroring network packets; Divided into N TCP connections; according to the N TCP connections, estimate the packet loss ratio Rx of the N TCP connections that are lost and do not detect retransmission handshake packets; according to the N TCP connections, estimate the N A packet loss ratio Ry of a TCP connection lost and no retransmitted data packet is detected; according to the Rx and the Ry, estimate the packet loss ratio of captured and port mirroring network packets. By using the embodiment of the present invention, the accuracy of packet loss ratio estimation and data analysis accuracy are improved.
Description
Technical field [0001] The present invention relates to the field of Internet technology, in particular to a method and device for estimating the packet loss ratio in the process of network packet capture. Background technique [0002] Network packet capture analysis is a commonly used network monitoring method and one of the core technologies of network operation and maintenance management. When analyzing the network packet capture, the network packet loss caused during the packet capture process is often overlooked. Packet capture refers to the interception, retransmission, editing, and dumping of network packets sent and received by network transmission. It can be used to check network security and is often used for data interception. [0003] The actual packet capture includes two processes of mirroring copying and capturing, which are based on two devices to capture packets. Grabbing refers to the use of professional hardware network cards to capture network packets, and the...
