Embodiment 1

[0025] Such as figure 1 As shown, a method for implementing a buffer snapshot in this embodiment includes:

[0026] Step S101, according to the path flow of the network data packet, record the real-time data;

[0027] In a specific implementation, the real-time data includes data such as queue statistics and port statistics, which are used to reflect the statistics of the packets received by the Ethernet switch. When a network data packet enters the buffer buffer of the Ethernet switch, according to the path process of the data packet in the switch, these data packets will be recorded in the switch, and these records can reflect the real-time data statistics of the Ethernet switch , working status and network throughput information.

[0028] Step S102, synchronizing the real-time data to an independent internal memory in real time;

[0029] The internal memory will not affect the statistics of the buffer area Buffer of the switch itself, so it will not affect the statistics...

Embodiment 2

[0037] This embodiment also discloses a device for realizing snapshots of cache areas, which includes: a recording unit for recording real-time data according to the path flow of network data packets; a synchronization unit for synchronizing the real-time data to a An independent internal memory; and, according to a control instruction, interrupting real-time synchronization; a reading unit, configured to realize a cache snapshot by reading the instant data stored in the internal memory.

[0038] In a specific implementation, the synchronization unit interrupts the data synchronization of the internal memory when the instruction is successfully issued according to the snapshot instruction issued by the Ethernet switch software.

[0039] In a specific implementation, when the synchronization unit reaches a preset threshold inside the Ethernet switch, the processing unit triggers an interruption of the internal memory data synchronization.

[0040] In a specific implementation, ...

Abstract

The invention discloses a cache region snapshot implementation method and device, and the method comprises the steps: recording instant data according to the access flow of a network data package; synchronizing the instant data to an independent internal memory in real time; interrupting real-time synchronization according to the control instruction; and realizing snapshot of the cache region by reading the instant data stored in the internal memory. By means of the cache region snapshot implementation method and device, the problem that in the prior art, reading of data records in a cache region cannot be recorded in time can be solved.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method and device for realizing a cache snapshot. Background technique [0002] An Ethernet switch is a switch that transmits data based on Ethernet, and is an important device in a local area network. The current Ethernet switch is fast and has a large throughput, and a slight delay will lead to inaccurate data recording in the buffer area of ​​the Ethernet switch, so that the effect of timely recording cannot be achieved, affecting real-time network throughput and Ethernet Monitor and judge the working condition of the switch. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is how to solve the problem in the prior art that the reading of data records in the buffer area cannot achieve timely recording. [0004] In order to solve the above problems, the technical scheme provided by the present invent...
