Method, device and system for detecting overload

Abstract

An embodiment of the invention discloses a method, a device and a system for detecting overload. The method disclosed by the embodiment of the invention comprises the following steps: transmitting a heartbeat message; when the response which is returned by a processor according to the heartbeat message is obtained in a preset time, obtaining the load information of processor according to the response; and determining whether overload is generated in the processor according to the load information. Through the embodiment of the invention, whether overload is generated in the processor can be inquired real time. The timeliness of detection is increased thereby reducing the potential safety hazard of device.

Description

technical field [0001] The present invention relates to the technical field of electronic communication, in particular to an overload detection method, device and system. Background technique [0002] In consideration of device reliability, it is necessary to perform overload detection on the processor in the device. When the processor is overloaded, some packets are transferred to other processing units for processing. [0003] Currently, there are two ways to detect the overload of the processor, which will be described respectively below. [0004] The first way is: the processor periodically sends an overload detection request to the distribution center, and the distribution center performs overload detection. [0005] The second method is: the distribution center regularly detects the backpressure signal, and when it finds the backpressure of the uplink or downlink channel, it is informed that the processor is overloaded. [0006] In the process of research, the inven...

AI Technical Summary

Problems solved by technology

[0006] During the research process, the inventor found that the above two methods of overload detection have at least the following disadvantages: the distribution center is easy to miss the opportunity of overload detection, which makes the equipment have potential safety hazards

Specifically, in the first way, when backpressure occurs on the downstream channel, the overload detection request sent by the processor cannot reach the distribution center, so that the distribution center misses the opportunity of overload detection

In the second method, when the processor is overloaded, the distribution center will not be able to know that the processor is overloaded before backpressure occurs in the upstream or downstream channels, thus missing the opportunity for overload detection
