Embodiment Construction

[0039] In the embodiment of the present invention, after receiving the first message sent by the video camera, the video server sends a backoff message to the video camera that sent the first message, instructing it to send the first message later when it finds itself in a processing bottleneck. The video server does not perform data processing on the first message, thereby reducing its own processing pressure and reducing the possibility of major accidents. And the video camera will send the first message again later, reducing the possibility of data processing omission.

[0040] Wherein, the processing bottleneck state is such as the memory reaches the preset storage threshold, or if the processing stack is full, or if the number of unprocessed messages reaches the preset number threshold, etc., of course, the processing bottleneck state is not limited to this, and will not be repeated here. List them all.

[0041] see figure 1 , the video monitoring system in this embodim...

Abstract

The invention discloses a processing method when a video server is congested, which is used for preventing message storm from being produced, and preventing accidents of the video server such as equipment halting caused by reaching processing bottleneck. The method comprises the following steps that: a video camera sends a first message to the video server; the video server analyzes an IP header from the first message when finding in a processing bottleneck state; an IP address of the video camera is acquired; the video server sends a backoff message to the video camera according to the acquired IP address; and after the video camera receives the backoff message, the video camera determines time delay duration according to a preset algorithm, and sends the first message to the video server again when the time delay duration is reached. The invention also discloses a device and a system for realizing the method.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to a processing method and device when a video server is congested. Background technique [0002] The current computer, network, communication, multimedia and other technologies are developing rapidly, making the video surveillance system maturely applied in all walks of life. And, the prior art has been developed to the third generation IP (Internet Protocol) network video surveillance system. For example, China Telecom's "Global Eye" and China Netcom's "Wide Vision" and other operator-level video surveillance systems, as well as the "city monitoring and alarm networking system" in various cities. [0003] An IP network video surveillance system includes a video camera for taking pictures and a video server for managing the video camera and processing video data. A video server may be connected to hundreds or even thousands of video cameras, and may need to process hund...
