Example 1
As shown in fig. 1, an implementation method of a cache snapshot in this embodiment includes:
step S101, recording instant data according to a path flow of a network data packet;
in specific implementation, the instant data includes data such as queue statistics and port statistics, and is used for reflecting statistics of packet receiving conditions of the ethernet switch. When a network data packet enters the Buffer of the Ethernet switch, the data packet is recorded in the switch according to the path flow of the data packet in the switch, and the information of the instant data statistics, the working state and the network throughput of the Ethernet switch can be reflected through the records.
Step S102, synchronizing the instant data to an independent internal memory in real time;
the internal memory does not affect the statistics of Buffer in the cache area of the switch, so that the statistics of the Ethernet switch on the next network data packet is not affected, and the independent statistics of distinguishing the instant data is carried out.
As shown in fig. 2, the switch Buffer synchronizes instant data to the independent memory in real time.
Step S103, interrupting real-time synchronization according to the control instruction;
in specific implementation, the data synchronization in the independent memory can be interrupted at the moment when the command is successfully issued according to the snapshot command issued by the user through software. As shown in fig. 3, after the software issues the snapshot instruction, the data synchronization of the Buffer to the independent memory is instantaneously completed, so that the instantaneous switch Buffer data is stored in the independent memory. Due to the fact that independent statistics for distinguishing the instant data is conducted through the independent internal memory, Buffer statistics in the original switch cannot be affected, the instant flow and the data using condition of the switch can be reflected, a user can clearly know the instant data condition of the switch, and the snapshot function is completed.
In specific implementation, a preset threshold may be configured inside the switch, and when the threshold value is reached, the interruption of data synchronization is triggered, and the snapshot effect may also be completed. As shown in fig. 4, a threshold set inside the switch may be used, and when the port statistics or the queue statistics reach the threshold, the snapshot function may be triggered, so that the user takes out the snapshot statistics in the independent memory.
Step S104, implementing a cache snapshot by reading the instant data stored in the internal memory.
According to the invention, the upper-layer user can intuitively know the current use condition of the network link according to the real-time response to the data flow of the switch, the use of the independent memory does not influence the original statistics, the network visualization precision is improved, and the adoption of instant data is realized.

In a specific implementation, the synchronization unit interrupts data synchronization with respect to the internal memory when the instruction is successfully issued according to a snapshot instruction issued by the ethernet switch software.
In a specific implementation, when the synchronization unit reaches a threshold preset in an ethernet switch, the processing unit triggers an interrupt to synchronize the data in the internal memory.
