Embodiment Construction
[0033] Aiming at the problems existing in the prior art, an embodiment of the present invention proposes a video data transmission method based on an aggregation network port, and the method is applied to a network device. by figure 1 The video monitoring system is a schematic diagram of the application scene of the embodiment of the present invention. The video monitoring system may include monitoring devices (such as front-end cameras and rear-end hard disk video recorders, etc.), media servers, network devices (such as switches or routers, etc.) and storage servers . Wherein, there may be multiple media servers, and four media servers are taken as an example for illustration. To implement link protection and load sharing, multiple physical network ports connected to the storage server are configured on the network device, and these physical network ports are configured as aggregation network ports. Wherein, the number of physical network ports can be selected according to...

The present invention provides an aggregation network interface-based video data transmission method and device. The method comprises the steps: receiving video data; performing HASH processing on address information and the number of virtual network interfaces carried in the video data, and selecting one virtual network interface from a plurality of virtual network interfaces according to HASH processing results; querying a pre-set mapping relationship table by the selected virtual network interface; if the selected virtual network interface exists in the mapping relationship table, sending the video data by a physical network interface, corresponding to the selected virtual network interface, in the mapping relationship table; and if the selected virtual network interface does not exist in the mapping relationship table, selecting a physical network interface corresponding to the smallest number of the virtual network interfaces, recording a corresponding relationship between the selected virtual network interface and the physical network interface in the mapping relationship table, and sending the video data by the physical network interface. By adopting the technical solution provided in the present invention, the problem of unbalanced HASH processing results is avoided, and the packet loss of the video data is reduced.
Description
technical field [0001] The invention relates to the field of video monitoring, in particular to a video data transmission method and device based on an aggregation network port. Background technique [0002] Such as figure 1 As shown in , it is a network diagram of the video surveillance system. In the video monitoring system, the media server collects video data from monitoring equipment (such as front-end cameras and back-end hard disk video recorders, etc.), re-encapsulates the video data, and sends the encapsulated video data to network equipment. The network device sends the video data to the storage server, and the storage server stores the video data received by itself. [0003] Usually, in order to realize link protection and load sharing, multiple physical network ports connected to the storage server are configured on the network device, and these physical network ports are configured as aggregation network ports. Based on this, when the network device sends vid...
