Problems solved by technology

Therefore, the current security isolation manufacturers adopt the method of opening port intervals to realize service access. Since the port intervals are relatively large and the ports are open for a long time, they are very easy to be attacked by third parties, which also brings certain security risks

Abstract

The invention provides a data transmission method of a gatekeeper. The gatekeeper comprises an outer end host and an inner end host; the gatekeeper is used for data transmission between a source terminal and a destination terminal, and the method comprises the following steps: S1, starting a preset port of the gatekeeper; S2, receiving a first message of the source terminal through the preset portby the outer end host, if the first message satisfies a preset rule, analyzing the first message, and repackaging the analyzed first message according to a preset protocol to generate a second message, and sending the second message to the inner end host, or abandoning the first message; S3, sending the message to the destination terminal through the preset port by the inner end host; and S4, closing the preset port.

Description

technical field [0001] The disclosure relates to a data transmission method, device, system and medium of a network gatekeeper. Background technique [0002] The private video network refers to a network dedicated to supporting video surveillance services and tandem video surveillance systems. High-density private networks (such as private networks of government departments, national defense and security departments, etc.) obtain video data in the video private network through a gatekeeper. The gatekeeper is composed of an external host and an internal host. It is mainly deployed between two different security domains to realize the video image retrieval requirements of different security level network domains. [0003] At present, all video surveillance manufacturers (such as Kedak, Dahua, Hikvision, H3C, etc.) use self-defined private protocols to realize the service access of real-time surveillance images, and there is no unified protocol application standard. Therefore...
