Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, in particular to a message flow detection method and device, a storage medium and an electronic device. BACKGROUND

[0002] At present, network deployment is more and more complex, which brings great difficulty to operation and maintenance personnel. By checking the service statistics of network equipment, the operation and maintenance personnel can quickly locate and solve problems. Due to the diversity of services, different services need to be statistically analyzed from different perspectives. For switches or routers, the statistical function is implemented by a switching chip. At present, for a certain service statistical requirement from a certain service perspective, the corresponding statistical method needs to be designed in the chip for the statistical requirement. For example, for VLAN service flow statistics, the number of packet loss messages in VLAN service of network equipment is counted. Therefore, for this statistical requirement, the index of VLAN service on the network equipment needs to be designed, and the statistical algorithm for counting the packet loss messages is designed for the statistical requirement, so that the chip supports this kind of statistical requirement. However, the statistical ability of such a chip is relatively fixed, and it can only support the statistics of fixed service statistical requirements. If the chip has been taped out, and there is a new statistical requirement at this time, the chip cannot meet the statistical requirement. Therefore, when designing the chip, the function design of the statistical requirement needs to be increased. With the continuous increase of the function design corresponding to the statistical requirement, the chip is designed to be relatively bloated.
