[0002] With the rapid development of Internet technology, network communication plays an increasingly important role in people's lives and work. However, packet loss often occurs during Internet transmission, which seriously affects network performance and brings a bad experience to users.

[0003] In the past, communication equipment could only perceive packet loss by counting the number of packets in and out of the port and then subtracting the difference. Although this method is simple and easy to use, it has obvious limitations. It cannot provide detailed packet loss statistics, is not conducive to the comprehensive perception of the device forwarding situation, and cannot accurately determine the cause of packet loss and the content of the discarded message. Summary of the invention

[0168] Prevent problems from happening again: By analyzing the packet loss analysis results, you can summarize lessons learned and develop corresponding preventive measures. This helps prevent similar network problems from happening again in the future and improves the overall reliability of the network.

[0169] It should be noted that packet loss often occurs during Internet transmission, which affects network performance. The packet loss sampling and statistics function can detect packet loss that occurs during the forwarding process of the message inside the device. When packet loss occurs, the device will sample the packet loss and send the sampling information to the CPU according to the sampling rate configured by the user. The CPU parses the five-tuple information of the packet loss message and finally presents the packet loss information to the user.

[0170] In the past, communication equipment could only detect packet loss by counting the number of messages in the port's inbound and outbound directions, subtracting the difference, and obtaining the number of lost packets.

[0173] 1. First, create the internal loopback interface loopbackA.

[0174] 2. Create the next hop nexthop B, and the exit of the next hop points to loopbackA.

[0175] 3. Change the ACL deny forwarding action to redirect to nexthop B.

[0176] 4. Set the next hop of the black hole route to nexthop B.

[0177] 5. Enable the port sampling function on loopback A and set the sampling rate.

[0178] 6. Send the sampled message to the CPU.

[0179] 7. The CPU parses the received message, extracts the five-tuple information, and feeds the information back to the client.

[0180] It should be noted that when the packet enters the switch device, it hits the ACL DROP rejection forwarding entry. The packet is not discarded directly, but redirected to the next hop B, and then redirected to the loopback A through the interface pointed to by the next hop. Enable the port sampling function on the loopback A and configure the sampling rate. The packet redirected to the loopback A is sent to the CPU controller through port sampling at the configured sampling rate. After receiving the packet, the CPU controller parses the five-tuple information of the packet and sends the five-tuple information to the client foreground to display to the user. The packet loss information is visualized.

[0181] The black hole routing message enters the switch device and hits the black hole routing table entry. The message is not discarded directly, but is also redirected to the next hop B. The subsequent forwarding process is the same as the above process.

[0182] The embodiments of this specification have the following beneficial effects:

[0183] 1. This solution can visualize packet loss through detailed packet loss statistics, and easily view the cause of packet loss and the specific content of packet loss, so as to achieve the purpose of accurate and rapid fault location.

[0184] 2. This solution can control the number of samples sent to the CPU by setting the sampling rate of the loopback port, thus avoiding sending all discarded packets to the CPU, which would cause excessive impact on the CPU and affect performance.
