Embodiment Construction

[0048] In view of the problems in the background technology, this application proposes a media stream forwarding method. By stacking multiple existing access boxes together, the actual media streams of social monitoring resources are allocated to different access boxes. At the same time, multiple access box collections perceive the device agent as if there is only one box, thus ensuring the continuity and reliability of media stream forwarding without making major changes to the existing video surveillance system network.

[0049] Such as image 3 As shown, it is a schematic flowchart of a media stream forwarding method proposed in this application, which is applied to a video surveillance system including device agents, social monitoring resources, and multiple access boxes. And the social monitoring resources in the video monitoring system can cover a wide variety of equipment types, such as NVR (Network Video Recorder, network hard disk video recorder)\DVR (Digital Video Re...

Abstract

This application discloses a media stream forwarding method and device. When the master access box judges that its own access capability cannot meet the bandwidth requirements of the monitoring service request, it determines the slave access box for forwarding the media stream and sends it to the device agent. Create a virtual channel request, and after notifying the slave access box and the device agent to establish a virtual tunnel corresponding to the virtual address pool of the network segment and obtain the virtual address corresponding to the virtual tunnel, send a virtual IP address as the source address to the slave access box media stream establishment message. Therefore, in the case of reducing the complexity of network structure adjustment, it can ensure the normal forwarding of media streams of massive social monitoring resources.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a media stream forwarding method. The present application also relates to a media stream forwarding device. Background technique [0002] In recent years, with the rapid development of computer, network, image processing and transmission technology, video surveillance technology has also made great progress. With the continuous advancement and deepening of the construction of the province's video surveillance system, the construction scale and coverage of video surveillance cameras are expanding day by day. The video surveillance cameras invested and constructed by ourselves accounted for 92.5% of the total surveillance cameras, which not only greatly ensured the safety of the unit, but also effectively made up for the lack of public surveillance resources and many surveillance blind spots. However, although there are a large number of video surveillance sy...
