Network packet loss notification method, monitoring device, switch and storage medium

Abstract

The invention relates to the technical field of computer networks, in particular to a network packet loss notification method, a monitoring device, a switch and a storage medium. The method comprisesthe following steps: identifying a target message from a received message flow; obtaining stage state information corresponding to the target message in each processing stage in real time; when determining that one piece of stage state information represents that the target message is discarded, setting an index of a counter as a preset value corresponding to the processing stage based on the processing stage to which the target message belongs; and triggering a counter to count based on the set index, correspondingly increasing the register value of the counter, and outputting correspondingincrease information which is used for diagnosing the specific position of packet loss. The function of automatically notifying the outside when the message is discarded is realized, the method is suitable for the switch for cross-chip forwarding, whether the switch has packet loss or not can be diagnosed, the port through which the target message passes can also be positioned, and the precision of the diagnosis position can be specifically applied to a part of processing stages in the switch.

Description

technical field [0001] The present application relates to computer network technology, in particular to a method for notifying network packet loss, a monitoring device, a switch and a storage medium. Background technique [0002] Network packet loss refers to the phenomenon that a small part of data in the data flow transmitted by the network cannot reach the designated destination through the network. The network packet loss rate refers to the ratio of the number of lost packets in the test to the total number of sent packets, and the calculation method is [(input packets - output packets) / input packets]*100%. In the network environment, there may be many reasons for network packet loss. For example, signal attenuation and channel blockage caused by multipath fading, network driver failure, switch failure, device configuration problems, and other device attacks may cause Network packet loss. [0003] Network packet loss may cause jitter in streaming media, online games, a...

AI Technical Summary

Problems solved by technology

For cross-chip forwarding switches, a large number of registers are involved in different chip pipeline stages. If the above method is used to diagnose network packet loss on cross-chip switches, the register information to be collected will increase exponentially, making the simulation analysis process extremely complicated. Diagnosis of network packet loss is not possible at all

That is, the above method does not apply to switches that forward across chips
