Referring to fig. 1, the present embodiment provides one of the flowcharts of a data processing method.
The data processing method provided by the embodiment of the invention comprises the following steps:
the data processing method of the embodiment of the invention is applied to a code stream processing system, and the code stream processing system comprises a code stream processing module and a protocol analysis module.
Step 101: and when the platform pulls the flow, determining the address port information of the signaling information.

The example illustrates the use of the method in a national standard process: GB/T28181-2011 is a national standard which is drafted by a plurality of units such as national security and protection alarm system standardization technical committee (SAC/TC 100) and one ministry of public security.
The national standard (GB 28181) flow is a flow in which a lower platform initiates registration, an upper platform receives passively, and a stream pulling process is a flow in which the upper platform sends an invite request to the lower platform, the invite request carries a stream receiving address, the lower platform then pushes a stream to the stream receiving address, the stream receiving address is a destination address port, and the stream pushing address is a source address port.
The platform can be an upper stage platform and a lower stage platform. The lower platform may be a device or a camera or a webcam.
In the network, various signals are transmitted, some of which are required (e.g. voice for making a call, data packets for accessing the internet, etc.) and others of which are not required (not directly required) for controlling circuits, and this type of signal is called signaling.
The codestream processing system further includes an SDN controller, which is an application in a Software Defined Network (SDN) responsible for flow control to ensure an intelligent network. SDN controllers are based on protocols such as OpenFlow, allowing servers to tell switches where to send packets.
Software Defined Networking (SDN) is a novel Network innovation architecture proposed by the clean-slate project research group of stanford university, usa, and is an implementation mode of Network virtualization. The core technology OpenFlow separates the control plane and the data plane of the network equipment, thereby realizing the flexible control of network flow, enabling the network to be more intelligent as a pipeline, and providing a good platform for the innovation of a core network and application.
The switch registers with the controller through the SDN.
A Switch means a "Switch" is a network device used for electrical (optical) signal forwarding. It may provide an exclusive electrical signal path for any two network nodes accessing the switch. The most common switch is an ethernet switch. Other common are telephone voice switches, fiber switches, and the like.
For the code stream processing system, firstly, the address port information of the interactive signaling information between the platforms is determined. Specifically, when the platform pulls the stream through the national standard protocol, the configuration rule of the user is determined; and determining the address port information of the signaling information according to the configuration rule of the user. Based on the address port information of the signaling information, the following two openflow rules, namely a first processing rule and a second processing rule, are generated:
OpenFlow, a network communication protocol, belongs to a data link layer, and is capable of controlling a forwarding plane (forwarding plane) of an on-network switch or router, so as to change a network path traveled by a network packet. OpenFlow can activate a remote controller to determine, via a network switch, which path a network packet is to traverse the network switch. OpenFlow allows the routing of packet forwarding to be changed by adding, modifying, and removing packet control rules and actions from the packet forwarding table of the remote control network switch.
The first processing rule is as follows: matching first signaling data with a destination address port as a platform address port, and copying; and changing the destination address port of the copied first signaling data into the address port of the protocol analysis module.
The protocol analysis module analyzes the first signaling data to obtain first address port information.
For example: and copying the invite request, and changing a destination address port of the invite request into an address port of the protocol analysis module.
The protocol analysis module analyzes the first signaling data to obtain first address port information of the code stream data.
For example: and the protocol analysis module analyzes the invite request to obtain a stream receiving address, wherein the stream receiving address is a destination address port.
The second processing rule is as follows: and copying the second signaling data with the matched source address port as the lower platform address port. And changing the destination address port of the copied second signaling data into the address port of the protocol analysis module.
The protocol analysis module analyzes the second signaling data to obtain second address port information of the code stream data.
For example: and the protocol analysis module analyzes the invite request to obtain a flow pushing address, wherein the flow pushing address is a source address port.
In the process of analyzing the protocol by the protocol analysis module, the superior platform sends an invite request stream to the subordinate platform or device or the camera, and if the code stream processing system configures the processing rule of the subordinate platform or device or camera, the following two openflow rules, namely a third processing rule and a fourth processing rule, are generated according to the destination address port and the source address port of the subordinate platform in the invite request and the address port of the code stream processing module corresponding to the code stream data.
The third processing rule: matching first target data of which the destination address port is first address port information; and changing the first address port information of the first target data into the address port of the code stream processing module.
For example: the lower platform sends code stream data to the upper platform, the first address port information is a destination address port, the second address port information is source address port information, the first address port information is a port of the upper platform at the moment, and the second address port information of the data is a port of the lower platform.
That is, the first target data whose destination address is the port of the upper stage platform is matched, and the destination address port of the first target data, that is, the first address port information, is modified into the address port of the code stream processing module.
The fourth processing rule: and determining that the source address port of the processed first target data is the data of the address port of the code stream processing module, and modifying the source address port of the data from the address port of the code stream processing module into second address port information.
Specifically, the matching source address is an address port of the code stream processing module to which the processed first target data corresponds, and the source address of the processed first target data is changed into an address port of the lower-level platform.
It should be noted that the first target data is processed according to a preset processing manner, where the preset processing manner includes, but is not limited to, any one of the following: encryption and decryption, watermark superposition, privacy blocking and intelligent coding.
The third processing rule can cut off the code stream data sent by the lower platform to the upper platform and transmit the code stream data to the code stream processing module; after the code stream processing module completes corresponding processing, the processed code stream data is sent to a stream receiving address port of a superior platform, but a source address port is the address port of the code stream processing module, and the source address port is changed into the address port of a subordinate platform, so that the superior platform can not completely perceive that the code stream data is processed.
According to the data processing method provided by the embodiment of the invention, when the platform pulls the stream, the address port information of the signaling information is determined; generating a first processing rule and a second processing rule for processing the signaling information according to the address port information of the signaling information; processing and analyzing the signaling information according to the first processing rule and the second processing rule to obtain address port information of the code stream data; generating a third processing rule and a fourth processing rule of the code stream data according to the address port information of the code stream data; according to a third processing rule, sending the code stream data to a code stream processing module in the code stream processing system; according to the fourth processing rule, the source address port of the code stream data processed by the code stream processing module is changed into the address port information of the code stream data, so that the source address port of the processed code stream data sent from the code stream processing module is changed finally, and the platform for receiving the processed code stream data realizes non-inductive receiving, namely the platform for receiving the code stream data does not find that the code stream data is sent from the code stream processing module but is pulled to send by the platform. Therefore, the enabling between the original upper and lower platforms or equipment and cameras can be completed through the code stream processing system without adjusting the upper and lower platforms or equipment and cameras.
Referring to fig. 2, the second embodiment provides a flow chart of a data processing method.
The data processing method provided by the embodiment of the invention comprises the following steps:
step 201: when the platform and the device pull streams through the onvif protocol, all devices in the environment are detected.
Sending a request for acquiring a code stream between a platform and equipment; according to the code stream acquisition request, the code stream processing system detects all the onvif devices in the environment through the device discovery function of the onvif protocol.
Step 202: and receiving the selection operation of the target device by the user.
Step 203: and responding to the selection operation, and the platform issues a code stream query request to the target equipment.
Step 204: and according to the request of the query code stream, determining the address port information of the signaling information between the platform and the target equipment.
Step 205: and generating a first processing rule and a second processing rule for processing the signaling information according to the address port information of the signaling information.
Step 206: and processing and analyzing the signaling information according to the first processing rule and the second processing rule to obtain address port information of the code stream data.
Step 207: and generating a third processing rule and a fourth processing rule according to the address port information of the code stream data.
Step 208: and sending the code stream data to a code stream processing module in the code stream processing system according to the third processing rule.
Step 209: and changing the source address port of the code stream data processed by the code stream processing module into the address port information of the code stream data according to the fourth processing rule.
This embodiment explains the method used in the flow of onvif (open network video interface forum):
the onvif (open network video interface forum) is a global open industry forum aimed at facilitating the development and use of global open standards for physical IP (Internet Protocol) based secure product interfaces. onvif created a standard for how IP products in video surveillance and other physical security areas communicate with each other. The ONVIF provides a standardized network open interface for network video products. Forums include security and IP specification requirements based on IETF (The Internet Engineering Task Force) and network service standards, and The specification version 1.0 includes The following aspects: IP configuration searching equipment, equipment management, image configuration, real-time monitoring, event analysis, PTZ (Pan/Tilt/Zoom, omnibearing movement, lens zooming and zooming control) camera control, video analysis and security protection.
The onvif process is initiated by a superior platform actively, and is actively connected with a subordinate platform, the superior platform actively issues a request URL (Uniform Resource Locator) for inquiring code stream to the subordinate platform, and then pulls stream to the subordinate platform through RTSP (Real Time Streaming Protocol), and determines address port information of signaling information between the platform and the target device according to the request for inquiring code stream.
And for the code stream processing system, sending a code stream acquisition request between the platform and the equipment, and detecting all the onvif equipment in the environment by the code stream processing system through the equipment discovery function of the onvif protocol according to the code stream acquisition request. According to the code stream acquisition request, the code stream processing system detects all the onvif devices in the environment through the device discovery function of the onvif protocol. The user selects a certain onvif device, namely the target device, determines the address port information of the signaling information between the platform and the target device, and generates the following two openflow rules, namely a third processing rule and a fourth processing rule, based on the address port information of the signaling information.
The third processing rule is: determining a first destination address port and a first source address port in a query code stream request; and modifying the first destination address port in the code stream data into an address port of the code stream processing module.
When the first destination address port of the code stream data is changed, the code stream data is sent to the platform instead of being sent to the code stream processing module, namely the code stream processing module intercepts and processes the code stream data.
The code stream processing module may process the received code stream data, for example: the embodiment of the present invention does not specifically limit the processes of encrypting the code stream data, decrypting the code stream data, adding watermarks to the code stream data for superposition, preventing the code stream data from being stolen, and privacy-shielding the sensitive image in the code stream data.
The fourth processing rule is as follows: and changing the source address port of the processed code stream data from the address port of the code stream processing module to the first source address port.
And the third processing rule can forward an rtsp request established by the platform to the equipment to the code stream processing module, the code stream processing module sends the rtsp request to the equipment after receiving the rtsp request, the equipment starts to send code stream data, and the code stream processing module performs corresponding processing after receiving the code stream data.
The fourth processing rule is used for sending the code stream processing module to the code stream data of the platform, including tcp (Transmission Control Protocol) handshake, rtsp signaling, rtmp (Real Time Messaging Protocol) Control, code stream data, and the like, changing the source address of the code stream data to the address port of the platform, otherwise, the operating system of the platform will not consider the response of the previous request, and discards the corresponding data.
In the data processing method provided by the embodiment of the invention, when the platform pulls the stream, based on the onvif flow, the code stream processing system intercepts the code stream data, processes the code stream data, and changes the address port of the processed code stream data into the source address port in the address port information, so that when the platform receiving the processed code stream data receives the code stream data, the platform receiving the code stream data realizes non-inductive receiving, namely the platform receiving the code stream data does not discover that the code stream data is sent from the code stream processing module but sent by the platform. Therefore, the enabling between the original upper and lower platforms or equipment or cameras can be completed through the code stream processing system without adjusting the upper and lower platforms or equipment or cameras.
