The invention discloses a method and a device for dynamically regulating the Qos (quality of service) of a video monitoring network. The method includes firstly, receiving packet loss information and acquiring information of media streams with packet loss and information of branch networks where media stream source equipment is located; secondly, respectively transmitting the information of the media streams to a headquarter VPN (virtual private network) gateway and branch VPN gateways of the branch networks where the media stream equipment is located, and informing the headquarter VPN gateway and the branch VPN gateways of detecting packet loss of the media streams; thirdly, receiving detection results from the headquarter VPN gateway and the branch VPN gateways, judging packet loss paths and informing of changing Qos priorities of the media streams in the paths. The invention further discloses the device for dynamically regulating the Qos. The device is applied to a center server and comprises an analysis module, a detection module and a regulation module. The method and the device have the advantages that the Qos of the integral network can be dynamically regulated by the method and the device, and accordingly the quality of user experience can be improved.
Description
technical field [0001] The invention belongs to the technical field of video monitoring, in particular to a Qos dynamic adjustment method and device in a video monitoring network. Background technique [0002] With the application of video surveillance in large and medium-sized enterprises with branches and chain industries, application-based VPNs are often used for monitoring networks across the Internet, such as figure 1 shown. The entire video surveillance system includes the headquarters network and multiple branch networks. The headquarters network includes the headquarters VPN gateway and the central server, and each branch network includes branch video devices and branch VPN gateways. [0003] When watching the live broadcast of the branches or playing back the video images of the branches at the enterprise headquarters, the branch VPN gateway of each branch network needs to establish a VPN connection with the headquarters VPN gateway of the headquarters network, and...
