A flow self-adaptive pressure reduction control method, device, equipment and medium

By using an adaptive decompression control method, the frequency of network data packet reading by upper-layer applications is reduced and non-core business data packets are discarded, thus solving the overload problem of the network traffic monitoring system under sudden traffic surges and achieving system stability and continuity of core monitoring functions.

AI Technical Summary

Technical Problem

When faced with sudden, high-concurrency abnormal traffic, existing network traffic monitoring systems suffer from system overload and crashes due to traditional traffic control and overload protection schemes, resulting in the interruption of core security monitoring functions and difficulty in accurately detecting the critical point of memory accumulation.

Method used

By monitoring the resource usage indicators of the system to assess the pressure status, an adaptive pressure reduction control method is implemented, including reducing the frequency at which upper-layer applications read network data packets from the driver layer packet capture cache, and discarding non-core business data packets at the application layer traffic collection entry point, thereby utilizing the first-in-first-out characteristic of the packet capture cache to achieve traffic trimming.

Benefits of technology

Under extreme traffic surges, it saves CPU and memory resources, improves the system's survivability and stability under high load, and ensures the continuity of core monitoring functions.

Abstract

The application discloses a flow self-adaptive decompression control method and device, equipment and medium, and relates to the technical field of computer network security and data processing. The method evaluates the pressure state by monitoring the resource occupation index of the system; when the first decompression trigger condition is met, the packet taking frequency of the upper application from the driving layer is reduced, and the flow is trimmed by using the natural overflow of the cache; when the first recovery control condition is met, the strategy is cancelled to recover the full amount of packet taking. The method of the application does not need to consume a large amount of CPU and memory resources, can accurately judge the pressure, and guarantees the system stability and core monitoring function continuity under high load.
