Description

Technical Field

[0001] The present application relates to the field of video surveillance technology, and in particular to a routing forwarding method, device, storage medium and routing forwarding gateway. Background Art

[0002] In the field of video surveillance, video surveillance devices need to interact with video surveillance services to implement functions such as registration, control, alarm, and video streaming of video surveillance devices. In order to enable video surveillance devices to communicate with corresponding video surveillance services, video surveillance devices are configured with a service address and multiple ports (such as HTTP port, RTSP port, etc.). At the same time, in the front-end proxy service, the video surveillance devices are bound to a video surveillance service instance respectively through manual binding. In this way, requests sent by the same video surveillance device through different ports can be uniformly forwarded to the same video surveillance service instance, ensuring that after the video surveillance device is registered with the video surveillance service, the same video surveillance service instance can communicate with the video surveillance device.

[0003] However, as more and more video surveillance devices are put into use, the load capacity of a single video surveillance service instance may reach its upper limit, so more video surveillance service instances need to be deployed to share the load. In this case, a set of service addresses and ports can be set for each video surveillance service instance, and the specified service addresses and ports can be configured on the video surveillance devices. However, this method makes the management of service instances, service addresses, and ports complicated and prone to errors, especially the need to manually configure the specified service addresses and ports for each video surveillance device, which is prone to single point server failure risks and network security risks.

[0004] In order to cope with the above situation, the existing technology usually adopts load balancing technology to meet the expansion requirements of large-scale video surveillance systems. However, the load balancer generally randomly distributes the requests sent by the video surveillance device to the video surveillance service instance. If the video surveillance device is successfully registered and not disconnected, the load balancer may forward the request sent by the same video surveillance device to different video surveillance service instances for processing. This affects the consistency and continuity of data interaction, which in turn easily reduces the accuracy of the data and affects the normal operation of the video surveillance service. Summary of the invention

[0005] The purpose of this application is to solve at least one of the above-mentioned technical defects, especially the technical defects of low consistency and continuity of data interaction in the prior art.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] The terms involved in this application are explained below.

[0049] Load balancing: A method of distributing traffic to multiple servers for processing, which can reduce request waiting time, thereby increasing the system's response speed and effectively improving the system's availability and performance.

[0050] HTTP (Hypertext Transfer Protocol): a request-response protocol;

[0051] RTSP (Real Time Streaming Protocol): an application layer protocol in the TCP / IP protocol system.

[0052] TCP (Transmission Control Protocol): a connection-oriented, reliable, byte-stream-based transport layer communication protocol;

[0053] IP (Internet Protocol): Network layer protocol in the TCP / IP system.

[0054] Video surveillance service: Provides video surveillance equipment with services such as device registration, signaling control, media forwarding, and other corresponding business functions.

[0055] It should be noted that the image / video acquisition, storage, use, processing, transmission, provision and disclosure involved in this application are in compliance with relevant laws and regulations and do not violate public order and good morals.

[0056] In one embodiment, Figure 1 As shown, the present application provides a video surveillance system, including: a routing and forwarding gateway 102, a video surveillance device 104 and at least one video surveillance server 106. The routing and forwarding gateway 102 is respectively connected to each video surveillance device 104 and each video surveillance server 106 for communication, and is used as an intermediate layer between the video surveillance device 104 and the video surveillance server 106.

[0057] The video surveillance server 106 is used to provide video surveillance services for the video surveillance device 104, including but not limited to any one or any combination of services such as registration, control, alarm, and cloud storage of video streams of the video surveillance device 104. It can be understood that the number of the video surveillance server 106 can be one or more, and the specific number can be determined according to the total number of video surveillance devices 104 in the video surveillance system and the data flow, which is not specifically limited herein.

[0058] The video monitoring device 104 refers to a device for collecting video image information to realize the monitoring function. For example, the video monitoring device 104 can be a camera. In the video monitoring system provided in the present application, the video monitoring device 104 is configured with the gateway address and port information corresponding to the routing forwarding gateway 102. For example, the routing forwarding gateway 102 can provide a unified public network server IP address and port information, and each video monitoring device 104 in the system can be configured with the public network server IP address and port information.

[0059] Specifically, since the video surveillance device 104 is configured with the gateway address and port information corresponding to the routing forwarding gateway 102, the video surveillance device 104 will send a corresponding request to the routing forwarding gateway 102 during the device registration and data interaction process. The routing forwarding gateway 102 can forward the request from the video surveillance device 104 to the corresponding video surveillance server 106 based on the routing forwarding method of any of the following embodiments, so as to provide video surveillance services to the video surveillance device 104 through the corresponding video surveillance server 106.

[0060] The routing forwarding method provided by this application is described below.

[0061] In one embodiment, Figure 2 As shown, the present application provides an application Figure 1 The routing forwarding method of the routing forwarding gateway shown specifically includes the following steps:

[0062] S202: In response to the received device registration request, determine a first target service from at least one registered service, and forward the device registration request to the first target service.

[0063] The device registration request is sent by the video surveillance device to request that the video surveillance device be registered in the video surveillance service. After the video surveillance device is registered in the corresponding video surveillance service, the corresponding video surveillance service can provide video surveillance services for the video surveillance device. The registered service refers to the video surveillance service that has been registered with the routing forwarding gateway. The first target service refers to the video surveillance service assigned to the video surveillance device that sent the device registration request.

[0064] In this step, since the video surveillance device is configured with the gateway address and port information corresponding to the routing forwarding gateway, when the video surveillance device needs to register the device, it can send a device registration request to the routing forwarding gateway. When the routing forwarding gateway receives the device registration request, it can determine the first target service from at least one registered service and send the device registration request to the first target service to register the video surveillance device that sent the device registration request (i.e., the registered surveillance device described in detail) to the first target service.

[0065] S204: If a first registration success message returned by the first target service in response to the device registration request is received, a forwarding correspondence between a service address corresponding to the first target service and a device identifier of the registered monitoring device is recorded.

[0066] The registered monitoring device is a video monitoring device that sends a device registration request.

[0067] In this step, after forwarding the device registration request to the first target service, the first target service can perform registration verification based on the received device registration request, and if the registration verification passes, register the registration monitoring device to this service and return the first registration success message to the routing forwarding gateway.

[0068] When the routing forwarding gateway receives the first registration success message, it can determine that the registered monitoring device has successfully registered with the first target service. In this case, the routing forwarding gateway can record the registered service address corresponding to the registered monitoring device and generate a forwarding correspondence between the service address corresponding to the first target service and the device identifier of the registered monitoring device.

[0069] S206: In response to the received data interaction request, query each forwarding correspondence according to the interaction device identifier, and obtain an address query result.

[0070] The data interaction request is sent by the video monitoring device to request data interaction with the video monitoring service. The interactive device identifier is the device identifier of the interactive monitoring device, and the interactive monitoring device is the video monitoring device that sends the data interaction request.

[0071] In this step, when receiving the data interaction request, the routing forwarding gateway can determine the device identification of the video surveillance device that sent the data interaction request and obtain the interaction device identification. For example, the routing forwarding gateway can extract the interaction device identification from the data interaction request.

[0072] After obtaining the interactive device identifier, the routing forwarding gateway can query the recorded forwarding correspondences according to the interactive device identifier to try to query the registration service address corresponding to the interactive monitoring device. It can be understood that if the routing forwarding gateway records the registration service address of the interactive monitoring device, the address query result can be the registration service address. If the routing forwarding gateway does not record the registration service address of the interactive monitoring device, the address query result is not the service address, for example, the address query result can be NULL or the query fails.

[0073] For example, if the routing forwarding gateway records the first forwarding correspondence and the second forwarding correspondence, and the first forwarding correspondence is device identifier 1-service address 1, and the second forwarding correspondence is device identifier 2-service address 2, then when the interactive device identifier is device identifier 1, the address query result is service address 1. Similarly, when the interactive device identifier is device identifier 2, the address query result is service address 2. When the interactive device identifier is device identifier 3, since the routing forwarding gateway does not record the forwarding correspondence corresponding to device identifier 3, the address query result may be NULL or the query fails.

[0074] S208: If the address query result is a service address, forward the data interaction request to the second target service.

[0075] The second target service is a registered service corresponding to the address query result, that is, a video monitoring service to which the interactive monitoring device has been registered.

[0076] In this step, when the address query result is a service address, it indicates that the routing forwarding gateway has recorded the registered service address corresponding to the interactive monitoring device. In this case, the routing forwarding gateway can forward the data interaction request to the corresponding registered service (i.e., the second target service), so that the interactive monitoring device can interact with the second target service.

[0077] It can be understood that, if the forwarding correspondence remains unchanged, the routing forwarding gateway can forward each data interaction request sent by the same video surveillance device to the same registered service, thereby providing homologous address forwarding for data interaction of the video surveillance device, thereby maintaining data consistency and continuity.

[0078] In this application, the routing forwarding gateway can receive a device registration request sent by a video surveillance device and forward the request to the corresponding video surveillance service, so that the video surveillance device can register at the corresponding video surveillance service. If the registration is successful, the routing forwarding gateway can generate and record the forwarding correspondence between the device identification of the video surveillance device and the corresponding service address, and forward the data interaction request accordingly.

[0079] In this way, by introducing a routing forwarding gateway as an intermediate layer, efficient and stable communication between video surveillance equipment and video surveillance services can be achieved, and then the communication interaction mode between the video surveillance equipment and the video surveillance service can be maintained without changing the communication interaction mode between the video surveillance equipment and the video surveillance service, while maintaining compatibility with existing communication protocols. On this basis, this application can implement homologous routing forwarding of data interaction requests based on the recorded forwarding correspondence, so as to forward the requests sent by the same video surveillance device to the same video surveillance service instance for processing as much as possible. In this way, the consistency and continuity of data interaction can be improved, and then the accuracy of the data can be improved and the normal operation of the video surveillance service can be affected.

[0080] In one embodiment, the routing forwarding gateway records the number of device registrations corresponding to the registered service, which refers to the number of video surveillance devices registered to the registered service. For example, when the number of device registrations corresponding to a certain video surveillance service is 10, it indicates that 10 video surveillance devices have successfully registered to the video surveillance service, and the video surveillance service is currently used to provide video surveillance services for the 10 video surveillance devices.

[0081] Determining a first target service in at least one registered service includes: determining the first target service in each registered service according to the number of device registrations corresponding to each registered service and a preset load balancing rule.

[0082] In this embodiment, after receiving the device registration request, the routing forwarding gateway can allocate the backend video monitoring service to the registered monitoring device according to load balancing rules such as the minimum number of connections, so as to realize load balancing function and realize flexible scheduling.

[0083] It is understandable that the specific content of the load balancing rule can be preset according to the actual situation, and this document does not impose specific restrictions on this. For example, when the load balancing rule is to allocate services based on the minimum number of connections, the routing forwarding gateway can determine the minimum number of registrations among the number of device registrations corresponding to each registered service when receiving a device registration request, and use the registered service corresponding to the minimum number of registrations as the first target service. In this way, the load balancing effect can be improved, thereby speeding up the response speed of the video surveillance service.

[0084] In one embodiment, the routing forwarding method provided by the present application further includes the following steps:

[0085] Step A1: if a first registration success message returned by the first target service in response to the device registration request is received, the first registration success message is returned to the registration monitoring device to instruct the registration monitoring device to periodically send a device keep-alive request to the routing forwarding gateway;

[0086] Step A2: judging whether the registered monitoring device is offline according to the reception of the device keep-alive request;

[0087] Step A3: If the registered monitoring device is offline, the forwarding correspondence corresponding to the registered monitoring device is deleted, and the number of device registrations corresponding to the first target service is updated.

[0088] In this embodiment, considering that after a video surveillance device is registered with a video surveillance service, it may be affected by power failure, communication obstruction, etc. and become offline, therefore, in this embodiment, the routing forwarding gateway can regularly monitor the online status of each registered video surveillance device, and when it is confirmed that the video surveillance device is offline, delete the forwarding correspondence corresponding to the video surveillance device and update the corresponding device registration quantity, so as to reduce the service resources occupied by the offline device, thereby improving the utilization of service resources.

[0089] Specifically, when the routing forwarding gateway receives the first registration success message returned by the first target service in response to the device registration request, it can determine that the registration monitoring device has been registered with the first target service. In this case, the routing forwarding gateway can return the first registration success message to the registration monitoring device. After receiving the first registration success message, the registration monitoring device periodically sends a device keep-alive request to the routing forwarding gateway.

[0090] It can be understood that when the registered monitoring device is online, the routing forwarding gateway can receive the device keep-alive request sent by the registered monitoring device at regular intervals. When the registered monitoring device is offline, the registered monitoring device cannot send the device keep-alive request, or the device keep-alive request sent by the registered monitoring device cannot be transmitted to the routing forwarding gateway, resulting in the routing forwarding gateway not receiving the device keep-alive request.

[0091] It can be seen that the routing forwarding gateway can determine whether the registered monitoring device is offline based on the reception of the device keep-alive request. In one example, when the routing forwarding gateway receives the device keep-alive request sent by the registered monitoring device, it can update the online active time corresponding to the registered monitoring device in real time. For example, the online active time can be updated to the latest reception time of the device keep-alive request. In this way, the routing forwarding gateway can determine whether the video monitoring device is offline based on each online active time.

[0092] When it is determined that the registered monitoring device is offline, the routing forwarding gateway can delete the corresponding forwarding correspondence and update the number of device registrations for the first target service corresponding to the registered monitoring device. In this way, the registration information of the offline device in the video monitoring system can be deleted, and the service resources occupied by the offline device can be reallocated.

[0093] In one embodiment, the routing forwarding method provided by the present application further includes the following steps: if the address query result reflects that the routing forwarding gateway does not record the forwarding correspondence corresponding to the interactive device identifier, a request failure message is returned to the interactive monitoring device.

[0094] The request failure message is used to instruct the interactive monitoring device to re-initiate a device registration request to the routing forwarding gateway.

[0095] In this embodiment, if the address query result reflects that the routing forwarding gateway does not record the registration service address corresponding to the interactive monitoring device, the routing forwarding gateway may return a request failure message to the interactive monitoring device. After receiving the request failure message, the interactive monitoring device may initiate a device registration request to the routing forwarding gateway to request that the device be registered in the video monitoring system.

[0096] In one embodiment, the registration step of the registered service in the routing forwarding gateway includes:

[0097] In response to the received service registration request, perform a registration check on the target registered service, and if the registration check passes, record a service address corresponding to the target registered service, and send a second registration success message to the target registered service;

[0098] The target registered service is a video surveillance service that sends a service registration request; and the second registration success message is used to instruct the target registered service to periodically send a service keep-alive request to the routing forwarding gateway.

[0099] In this embodiment, it is considered that after the video surveillance service is registered with the routing forwarding gateway, it may be affected by power failure, communication obstruction, etc., causing the server to be offline, thereby affecting the normal operation of the video surveillance service. Therefore, in this embodiment, the routing forwarding gateway can periodically monitor the service status of each registered service to facilitate scheduling according to the service status of the registered service, thereby ensuring the normal operation of the video surveillance service.

[0100] Specifically, the video surveillance service can send a service registration request to the routing forwarding gateway to request that the video surveillance service be registered in the routing forwarding gateway. When the routing forwarding gateway receives the service registration request, it can perform a registration check on the target registered service that sent the service registration request, and record the service address corresponding to the target registered service if the registration check passes, so as to facilitate the subsequent forwarding of the request sent by the video surveillance device to the target registered service.

[0101] When the target registered service registration verification passes, the routing forwarding gateway may also send a second registration success message to the target registered service. After receiving the second registration success message, the target registered service may periodically send a service keep-alive request to the routing forwarding gateway.

[0102] It can be understood that when the target registered service is in normal working state, the routing forwarding gateway can receive the service keep-alive request sent by the target registered service at regular intervals. When the target registered service is in a faulty state, the target registered service cannot send the service keep-alive request, or the service keep-alive request sent by the target registered service cannot be transmitted to the routing forwarding gateway, resulting in the routing forwarding gateway not receiving the service keep-alive request.

[0103] It can be seen that the routing forwarding gateway can detect the service status of the target registered service according to the reception of the service keep-alive request.

[0104] Furthermore, in one embodiment, the routing forwarding method provided by the present application may also include the following steps:

[0105] According to the reception of the service keep-alive request, determine whether the target registered service is faulty;

[0106] If the target registered service fails, the forwarding correspondence corresponding to the target registered service and the registration information of the target registered service in the routing forwarding gateway are deleted.

[0107] In this embodiment, the routing forwarding gateway can determine whether the target registered service is faulty according to the reception of the service keep-alive request. In one example, when the routing forwarding gateway receives the service keep-alive request sent by the target registered service, it can update the online active time corresponding to the target registered service in real time, for example, the online active time can be updated to the latest reception time of the service keep-alive request. In this way, the routing forwarding gateway can determine whether each registered service is faulty according to each online active time.

[0108] When it is determined that the target registered service fails, the routing forwarding gateway can delete all forwarding correspondences corresponding to the target registered service, as well as the registration information of the target registered service in the routing forwarding gateway. In this way, when the video surveillance device originally registered to the target registered service initiates a data interaction request, the routing forwarding gateway will return a request failure message to it to instruct the video surveillance device to re-initiate the device registration request, so that the routing forwarding gateway can assign the video surveillance to other video surveillance services. In this way, the video surveillance system can have disaster recovery capabilities, and even if some registered services fail, video surveillance services can be provided to the video surveillance devices in the system through other registered services that are not faulty.

[0109] In one embodiment, Figure 3 As shown, the present application provides an application Figure 1 The routing and forwarding method of the video surveillance system shown in the figure specifically includes the following steps:

[0113] S304: After receiving the second registration success message, the video surveillance service periodically sends a service keep-alive request to the routing forwarding gateway;

[0122] S313: The routing forwarding gateway returns a first registration success message to the video surveillance device;

[0132] S323: When the video surveillance device is offline / the video surveillance service fails, the device online active time / the service online active time times out, and the routing forwarding gateway clears the recorded forwarding correspondences and updates the number of device registrations for the video surveillance service;

[0133] S324: The routing forwarding gateway returns a response message to the video surveillance device / video surveillance service according to the cleanup / update result.

[0134] In this example, after the video surveillance service cluster is deployed and launched, it can register the service address information such as the intranet address and port of the service with the routing forwarding gateway, and support the periodic reporting of the service availability status through the status keep-alive function. In addition, after receiving the device registration request, the routing forwarding gateway can forward the request to the backend video surveillance service for registration verification according to the forwarding policy allocation such as the minimum number of connections to realize the scheduling function. In the case of a service failure and the failure to send a status keep-alive request, the online active time of the routing forwarding gateway is detected to have timed out and not updated in time, triggering the routing forwarding gateway to clean up the corresponding device registration backend service address and the device registration data of the backend service in time, so that the video surveillance device can re-initiate the device registration request and have disaster recovery capabilities.
