[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] The visual Internet is an important milestone in the development of the Internet. It is a real-time network that can realize real-time transmission of high-definition video and push many Internet applications towards high-definition video and high-definition face-to-face communication.

[0061] The visual network adopts real-time high-definition video exchange technology. It can integrate the required services such as high-definition video conferencing, video monitoring, intelligent monitoring analysis, emergency command, digital radio and television, delayed TV, online teaching, live broadcast, VOD on demand, TV mail, personalized recording (PVR), intranet (self-operated) channels, intelligent video broadcast control, information release and dozens of other video, voice, picture, text, communication, data and other services on a single system platform, and realize high-definition quality video playback through TV or computer.

[0062] Based on the above characteristics of the visual network, one of the core concepts of an embodiment of the present invention is proposed. In accordance with the protocol of the visual network, a business anomaly simulation instruction sent by a business anomaly detection terminal is received, and the anomaly simulation instruction includes an abnormal device type identifier, an anomaly type, an anomaly number and a business identifier; according to the business identifier, the anomaly number and the business corresponding to the anomaly type, the anomaly response information corresponding to the abnormal device type identifier is determined; according to the anomaly response information, the business execution result corresponding to the abnormal device type identifier is determined; the business execution result is sent to the business anomaly detection terminal, so that the business anomaly detection terminal determines the ability of the visual device corresponding to the abnormal device type identifier to handle abnormal state business according to the business execution result, and performs abnormal situation simulation detection on each visual device through the business anomaly detection system to judge the ability of the visual device to handle abnormal situations. When the abnormal situation occurs in the process of the visual network business, normal business can be carried out to ensure the stable operation of the visual network business.

[0063] The glossary is explained as follows:

[0064] Visual connection equipment: terminal equipment (Qiming, Jiguang, etc.), main control equipment and sub-control equipment of the core server, conference management server, network management server, etc.

[0065] An embodiment of the present invention provides an abnormal state test method for performing a state detection on a video connection device. The execution subject of this embodiment is an abnormal state test device, which is arranged on the video connection device.

[0066] Reference Figure 1 , shows a flowchart of an abnormal state testing method embodiment of the present invention, the method may specifically include the following steps:

[0067] S101, receiving a service anomaly simulation instruction sent by a service anomaly detection terminal, where the service anomaly simulation instruction includes an abnormal device type identifier, an abnormality type, an abnormality number, and a service identifier;

[0068] Specifically, in visual network services, visual network devices often experience abnormal scenarios such as service packet loss, service packet duplication, service tampering packets, and service damaged packets. Since the visual network devices are unable to handle or handle these scenarios incorrectly, the visual network services are interrupted. In this regard, an embodiment of the present invention provides an abnormal state testing method, which is applied to an abnormal state testing system. The abnormal state testing system is installed on a service anomaly detection terminal. The service anomaly detection terminal is used to issue service anomaly simulation instructions to simulate various abnormal scenarios, such as service packet loss, service duplication, etc.

[0069] The service anomaly detection terminal sends a service anomaly simulation instruction to the visual device, and the service anomaly simulation instruction includes an abnormal device type identifier, an abnormal type, an abnormal number of times and a service identifier, wherein the abnormal device type identifier includes at least one of the visual network number of the main control device, the visual network number of the sub-control device and the visual network number of the visual network terminal device, and the abnormal device type identifier is used to determine the identification of the abnormal source device; that is, the service anomaly detection terminal wants to perform an abnormal simulation detection on which visual device, and the identifier of which visual device is included in the service anomaly simulation instruction, and the abnormal type includes at least: a service packet loss type, a service duplication packet type, a service tampering packet type or a service damage packet type, and the service identifier includes at least one of video conferencing and videophone.

[0070] For example, if you want to perform abnormal simulation detection on the main control device of the video connection device, the abnormal device type identifier is the main control device identifier; if you want to perform abnormal simulation detection on the sub-control device of the video connection device, the abnormal device type identifier is the sub-control device identifier; if you want to perform abnormal simulation detection on the terminal device of the video connection device, the abnormal device type identifier is the terminal device identifier;

[0071] If the business anomaly simulation instruction may include the main control device identification, business packet loss, 3 times and start of the meeting, that is to say, the business anomaly detection terminal controls the main control device to execute the start of the meeting instruction, and the first 3 data packets are subjected to packet loss processing, that is, the main control device performs packet loss processing on the data packets and cannot send them to the sub-control device, nor can the terminal device be added to the meeting. When 3 data packets are lost, the main control device continues to send data packets to the sub-control device to allow the terminal device to join the meeting.

[0072] S102, determining the abnormal response information corresponding to the abnormal device type identifier according to the service identifier, the number of abnormalities, and the service corresponding to the abnormal type;

[0073] Specifically, the visual device determines the abnormal response information corresponding to the abnormal device type identifier according to the service identifier, the number of abnormalities and the service corresponding to the abnormal type in different abnormality scenarios;

[0074] Exemplarily, if the abnormality type is a service packet loss type: the video connection device does not return a service response packet to the service abnormality detection terminal;

[0075] If the exception type is a service repetition packet type: the video connection device returns the same service response packet corresponding to the number of exceptions. For example, if the number of exceptions is 4, the video connection device generates 4 identical service response packets.

[0076] That is to say, the abnormal response information corresponds to the abnormal device type identifier, for example, the master control device corresponds to the abnormal response information of the master control, the sub-control device corresponds to the abnormal response information of the sub-control, etc.; the abnormal response information may be not returning a business response packet, returning multiple response packets, returning a business tampering response packet, or returning a business damage response packet.

[0077] S103, determining the service execution result corresponding to the abnormal device type identifier according to the abnormal response information;

[0078] Specifically, the visual terminal determines the service execution result corresponding to the main control device, sub-control device or terminal device according to the abnormal response information in different scenarios;

[0079] For example, for a terminal device, if the terminal device performs packet loss processing and the main control device does not receive a response to the terminal device's joining result, the main control device will notify the terminal device to join the meeting again after a specified period of time until receiving a response result of successful joining from the terminal device. The main control device records the service status of each terminal device, for example, in some cases, the terminal device fails to join the meeting, and in some cases, the terminal device succeeds in joining the meeting.

[0080] If the terminal device performs service duplicate packet processing, and the main control device receives multiple identical response packets, the main control device processes the first response packet and discards the other response packets without processing. In this case, the terminal device can also join the conference successfully.

[0081] In an embodiment of the present invention, the main control device records the service execution results of each video connection device in different abnormal scenarios, such as service success or service failure.

[0082] S104. Send the service execution result to the service anomaly detection terminal, so that the service anomaly detection terminal determines the capability of the video connection device corresponding to the abnormal device type identifier to process the abnormal state service according to the service execution result.

[0083] Specifically, the visual device sends the service execution result to the service anomaly detection terminal. In this way, the service anomaly detection terminal can also obtain the service status of each visual device from the main control device in the visual device, and then compare the service status with the service execution result to determine whether the processing of each visual device in response to abnormal scenarios is correct, and determine the ability of the main control device, sub-control device or terminal device to handle abnormal status services.

[0084] The abnormal state testing method provided by the embodiment of the present invention receives a business abnormality simulation instruction sent by a business abnormality detection terminal, where the abnormal simulation instruction includes an abnormal device type identifier, an abnormality type, a number of abnormalities and a business identifier; determines the abnormal response information corresponding to the abnormal device type identifier according to the business identifier, the number of abnormalities and the business corresponding to the abnormal type; determines the business execution result corresponding to the abnormal device type identifier according to the abnormal response information; sends the business execution result to the business abnormality detection terminal, so that the business abnormality detection terminal determines the ability of the visual device corresponding to the abnormal device type identifier to handle the abnormal state business according to the business execution result, performs abnormal situation simulation detection on each visual device through the business abnormality detection system, judges the ability of the visual device to handle the abnormal situation, and when the abnormal situation occurs in the visual network business process, can carry out normal business, thereby ensuring the stable operation of the visual network business.

[0085] Another embodiment of the present invention further supplements the abnormal state testing method provided in the above embodiment.

[0086] like Figure 2 FIG. 1 is a flowchart showing another abnormal state testing method embodiment of the present invention, wherein the abnormal state testing method comprises:

[0087] S201, receiving a service anomaly simulation instruction sent by a service anomaly detection terminal, where the anomaly simulation instruction includes an abnormal device type identifier, an abnormality type, an abnormality number, and a service identifier;

[0088] Specifically, the abnormal device type identifier includes at least one of the visual network number of the main control device, the visual network number of the sub-control device and the visual network number of the visual network terminal device. The abnormal device type identifier is used to identify the abnormal source device; the service identifier includes at least one of video conferencing and video calling.

[0089] Since step S202 is Figure 1 The step S101 in the illustrated embodiment is the same. Figure 1 Step S101 has been described in detail in the specification, so step S202 will not be described again here.

[0090] S202, determining the abnormal response information corresponding to the abnormal device type identifier according to the service identifier, the number of abnormalities, and the service corresponding to the abnormal type;

[0091] Specifically, the visual device determines the abnormal response information corresponding to the abnormal device type identifier according to the service identifier, the number of abnormalities and the service corresponding to the abnormal type in different abnormality scenarios;

[0092] As an optional implementation method, if the abnormality type is a service packet loss type, no service response packet is returned; that is, the visual connection device does not return a service response packet to the service abnormality detection terminal;

[0093] As another optional implementation, if the exception type is a service repetition packet type, the same first service response packet corresponding to the number of exceptions is returned;

[0094] As another optional implementation, if the exception type is a service tampering packet type, a second service tampering response packet is generated, wherein service data in the second service response packet is tampered;

[0095] As another optional implementation, if the exception type is a service damage packet type, a third service damage response packet is generated, wherein service data in the third service damage packet is lost.

[0096] S2031. If the abnormal type is a service packet loss type, the main control device sends a service start instruction to the visual network terminal through the sub-control device at preset intervals until a first response result indicating a successful service is received from the visual network terminal;

[0097] S2032: If the exception type is a service duplication packet type, the master control device filters the same first service response packets corresponding to a preset number of exceptions to obtain a first service response packet;

[0098] S2033. If the abnormal type is a service tampering packet type, the master control device parses the second service tampering response packet to obtain a second service response packet, and judges the second service response packet. If the content in the second service response packet does not comply with the visual networking protocol or the content in the second service response packet is tampered with, the master control device sends a service start instruction to the visual networking terminal through the sub-control device at a preset time interval until receiving a second response result indicating that the service is successful from the visual networking terminal;

[0099] For example, taking the terminal device as an example, the main control device receives the tampered response packet returned by the terminal, and the main control device parses the response packet. If the content in the response packet does not conform to the visual network protocol, the parsing fails, and it is considered that the terminal device has failed to join the meeting. The main control device will notify the terminal to join the meeting again after a specified period of time until it receives a successful response result returned by the terminal device;

[0100] If the tampered response packet complies with the visual networking protocol, the main control device determines whether the response packet data has been tampered with based on the data in the sent service packet. If tampering is found, the terminal will be notified again to join the meeting after a specified period of time. Key parameters include: terminal device number, service type, service ID, whether there is a service processing result parameter (0 means success, other means failure), etc.

[0101] S2034. If the abnormal type is a service damage packet type, the main control device parses the third service damage packet to obtain the third service damage packet. If the third service damage packet does not comply with the visual networking protocol or the content in the third service damage packet is lost, the main control device sends a service start instruction to the visual networking terminal through the sub-control device at a preset time until a third response result indicating service success is received from the visual networking terminal.

[0102] Exemplarily, the main control device receives a damaged response packet returned by the terminal, and the main control device fails to parse it according to the visual networking protocol, and then notifies the terminal device to join the meeting again after a specified period of time;

[0103] The main control device notifies the terminal device to join the meeting again after a specified period of time. If the terminal device returns a successful joining, the main control device returns a terminal conference status notification to the abnormal simulation system. The main parameters include: operation code (terminal joining notification), terminal device number, conference global identifier, conference name, terminal status (in meeting), etc.

[0104] S204. The main control device determines the service execution result corresponding to the abnormal device type identifier according to one or more of the first service response result, the first service response package, the second service response result, and the third service response result, wherein the service execution result includes the first service status information of the visual connection device.

[0105] S205, the service anomaly detection system obtains first service status information of the visual connection device in the service execution result;

[0106] S206, the service anomaly detection system obtains the second service status information of each visual connection device in the service record table stored on the main control device;

[0107] S207, the service anomaly detection system compares the first service status information with the second service status information;

[0108] S208. If the first service status information and the second service status information are different, the service anomaly detection system determines that the video connection device has the ability to process abnormal services.

[0109] Specifically, the main control device eventually returns two response packets, "start conference response result" and "terminal conference status notification", to the business anomaly detection system; if the start conference response result is successful, the conference joining result of the participating terminal device is counted according to the terminal conference status notification, that is, the first business status information;

[0110] At the same time, the business anomaly detection system obtains the business status of the participating terminal device, that is, the first business status information, and compares it with the second business status information of each participating terminal recorded in the conference list on the main control device. If there is a difference, it means that the video connection device has processed incorrectly in the above-mentioned abnormal scenario; if the two are the same, it means that the video connection device has processed correctly in the above-mentioned abnormal scenario and the video connection device has a strong ability to handle abnormal business.

[0111] Figure 3 FIG. 1 is a schematic diagram of the structure of an abnormal state test system embodiment of the present invention. Figure 3 As shown, the abnormal state test system includes a business anomaly detection terminal and a visual connection device, wherein the visual connection device includes a main control device, a sub-control device and a terminal device. A business anomaly detection system is installed on the business anomaly detection terminal, and various simulation scenarios can be customized for the visual connection device. The visual connection device simulates the set abnormal scenarios during the business process. The business anomaly detection system obtains data of random length and sends it to the corresponding business receiving device. The business anomaly detection system counts the business processing results returned by each receiving device; the business anomaly detection system notifies the tested device to take effect on the simulated anomaly, and initiates a visual connection service for the tested device. The tested device starts the service and performs an abnormal simulation according to the effective simulation scenario. The business anomaly detection system counts the business processing results of the visual connection device and determines the ability of different visual connection devices to handle abnormal state services.

[0112] Figure 4 FIG. 1 is a flowchart of another abnormal state testing method embodiment of the present invention. Figure 4 As shown, the abnormal state testing method includes:

[0113] 1. The business anomaly detection system is connected to the core server through TCP socket, and logs in to the core server using the account registered on the core server; the core server includes the main control device and the sub-control device;

[0114] 2. The service anomaly detection system encapsulates the service anomaly simulation instruction to notify the device that needs to simulate the anomaly, such as the main control device, sub-control device or terminal device. The instruction package follows the visual network protocol. The main parameters include: operation code (service anomaly simulation), anomaly type, number of anomalies, service identification, list of terminal devices that need to simulate anomalies, etc.; anomaly types mainly include: service packet loss, service duplication packet, service tampering packet, service damage packet, etc.; number of anomalies: indicates the number of times the device simulates the anomaly, and returns to normal after exceeding the number of times;

[0115] 3. After receiving the service abnormality simulation instruction, the main control device forwards it to the sub-control device corresponding to the receiving terminal device, and finally the sub-control device notifies the receiving terminal device.

[0116] 4. After receiving the service anomaly simulation instruction, the terminal device saves and takes effect, and returns the setting result response package to the service anomaly detection system;

[0117] 5. The business anomaly detection system encapsulates the business package to detect whether the settings are effective. The business package follows the visual network protocol. The business package is forwarded to the sub-control device through the main control device, and then sent to the terminal device by the sub-control device to pull up the business;

[0118] 6. After receiving the service package, the terminal device detects whether to simulate abnormal services and whether the number of simulations, i.e. the number of abnormalities, exceeds the set number:

[0119] If abnormal business is not simulated or the number of simulations exceeds the set number, normal business will be performed;

[0120] Simulate packet loss: The terminal device starts the service but does not return the service result response packet to the main control device;

[0121] Simulate repeated service packets: The terminal device starts the service and returns multiple identical service response packets to the main control device;

[0122] Simulate service tampering packet: The terminal device starts the service and returns a service response packet with tampered content to the main control device;

[0123] Simulate a damaged service packet: The terminal device starts the service and returns an incomplete service response packet to the main control device;

[0124] 7. The main control device receives the service response packet returned by the terminal device and performs corresponding service processing according to the service response packet result. Taking the start of conference service as an example, the main control device notifies the terminal device to join the conference:

[0125] 7-1) Packet loss of terminal device: The main control device does not receive the response of the terminal device's joining result. The main control device will notify the terminal to join the meeting again after a specified period of time until it receives a response result of successful joining from the terminal device.

[0126] 7-2) Duplicate terminal device service packets: When the master device receives multiple identical response packets, the master device processes the first response packet and discards the other response packets without processing.

[0127] 7-3) The main control device receives the tampered response packet returned by the terminal, and parses the response packet. If the content in the response packet does not conform to the video networking protocol, the parsing fails and the terminal device is considered to have failed to join the meeting. The main control device will notify the terminal to join the meeting again after a specified period of time until it receives a successful response from the terminal device;

[0128] If the tampered response packet complies with the visual networking protocol, the main control device determines whether the response packet data has been tampered with based on the data in the sent service packet. If tampering is found, the terminal device will be notified again after a specified period of time to join the meeting. The key parameters include: terminal device number, service type, service identifier, whether there is a service processing result parameter (0 means success, other means failure), etc.

[0129] 7-4) The main control device receives the damaged response packet returned by the terminal device. If the main control device fails to parse the packet according to the visual networking protocol, it will notify the terminal device to join the meeting again after a specified period of time;

[0130] 8. The main control device notifies the terminal device to join the meeting again after a specified period of time. If the terminal device returns that the meeting is successfully joined, the main control device returns the terminal meeting status notification to the abnormal simulation system. The main parameters include: operation code (terminal meeting notification), terminal number, conference global identifier, conference name, terminal status (in meeting), etc.

[0131] 9. The main control device finally returns two response packets, "start meeting response result" and "terminal meeting status notification", to the business anomaly detection system;

[0132] 9-1) If the response result of starting the conference is successful, the joining results of the participating terminal devices are counted according to the terminal conference status notification. If the terminal device simulates abnormal times exceeding the set times and the main control device does not report the terminal conference status notification, it means that the main control device or the terminal device handles the above abnormal simulation incorrectly. The errors may be:

[0133] a. The main control device fails to notify the terminal to join the meeting again after the terminal loses the packet, receives a tampered packet, or receives a damaged packet;

[0134] b. The master device performs abnormal analysis after receiving a tampered or damaged packet;

[0135] c. The main control device returns multiple (greater than 1) identical terminal conference status notifications to a terminal device at the same time, indicating that the main control device handles duplicate packets incorrectly and does not perform filtering;

[0136] d. The terminal device is already in service and receives multiple notifications from the master device to join the conference, but an error occurs.

[0137] At the same time, the business anomaly detection system obtains the first business status of the participating terminal device and compares it with the second business status of each participating terminal recorded in the conference list on the main control. If there is a difference, it means that the main control device and the sub-control device have processed errors in the above abnormal scenario.

[0138] In addition to performing the above-mentioned abnormal simulation on the terminal device, the embodiment of the present invention can also perform the above-mentioned abnormal simulation on other video-linked devices, such as performing abnormal simulation on the sub-control device, or performing abnormal simulation on the main control device:

[0139] The simulation process of the sub-control device and the main control device is the same as the operation of the above-mentioned terminal device, which will not be repeated here;

[0140] After receiving the service packet, the sub-control device detects whether to simulate abnormal service and whether the number of simulations exceeds the set number: if abnormal service is not simulated or the number of simulations exceeds the set number, it is normal service; simulated packet loss: the sub-control device discards the received data packets until the number exceeds the set number (for example, if the packet loss is set to 100 times, 100 service packets will be discarded); simulated service duplicate packets: the sub-control device forwards multiple identical data packets to the terminal device and the main control device; simulated service tampered packets: the sub-control device forwards service packets with some tampered content to the terminal device and the main control device;

[0141] Simulated damaged service packets: The sub-control device returns incomplete service packets to the terminal device and the main control device.

[0142] The main control device and the terminal device receive the data packets forwarded by the sub-control device, and perform corresponding business processing according to the received data packets. The processing results are finally reported to the business anomaly detection system, which analyzes whether the detected device and peripheral devices process the above anomalies normally. For example, if two notification boxes for joining the meeting (the same meeting) pop up on the terminal device, it means that the terminal device does not process the duplicate packets; if the terminal crashes or does not respond after receiving a tampered or damaged packet, it means that the terminal handles the anomaly incorrectly; in the packet loss scenario, the number of packet losses has exceeded the set number, and the business is not started in the end, it means that the main control device may not initiate the business again, or the terminal device is abnormal, etc.

[0143] When the sub-control device sends an abnormal packet, the performance of the terminal device is specifically detected:

[0144] The terminal device receives an abnormal packet forwarded by the sub-control device. Take the start of a conference service as an example. If the main control device notifies the terminal device to join the conference through the sub-control device:

[0145] 1) Packet loss in sub-control device: If the terminal device does not receive the joining notification forwarded by the sub-control device, the terminal device fails to join the meeting. The main control device will notify the terminal to join the meeting through the sub-control device again after a specified period of time until the sub-control device exceeds the set number of packet losses. Then the main control device will forward the joining notification to the terminal device. After receiving the joining notification, the terminal device will perform corresponding business processing and return a successful joining response result.

[0146] 2) The sub-control device sends a duplicate service packet to the terminal device: When the terminal device receives multiple identical conference joining notifications, the terminal device processes the first notification packet and discards the other notification packets without processing.

[0147] 3) The sub-control device sends a tampered response packet to the terminal device:

[0148] a. The terminal device parses the response packet. If the content in the response packet does not conform to the visual networking protocol, the parsing fails and the terminal device discards it without processing the joining failure. The main control device will notify the terminal to join the meeting again through the sub-control after a specified period of time until the terminal device returns a successful joining response result; if the main elements of the joining notification command packet are: operation code (notifying the terminal to join the meeting), service identifier, conference global identifier, sender address, receiving terminal device address, etc.;

[0149] b. If the tampered response packet complies with the visual networking protocol, but the service type in the packet has been tampered with, the terminal device obtains the service type. If the service type does not belong to the visual networking service, it will be discarded and the joining failure will not be processed. The main control device will notify the terminal to join the meeting again through the sub-control after a specified period of time until the terminal device returns a successful joining response result;

[0150] c. If the tampered response packet complies with the visual networking protocol, but the sender address in the service packet has been tampered with, the terminal device continues the service and returns the joining result to the tampered address to detect the service exception handling capability in this abnormal scenario.

[0151] 4) The sub-control device sends a damaged service package to the terminal device. The terminal device fails to parse the package according to the visual network protocol and fails to join the meeting. The main control device will notify the terminal device to join the meeting again through the sub-control device after a specified period of time until the terminal device returns a successful response result.

[0152] If you cannot determine whether the problem is with the master device or the terminal device, you need to confirm it by capturing packets or checking the logs on the master device or the terminal device.

[0153] The embodiment of the present invention can also perform abnormal simulation detection on the main control device. The various abnormal packets sent by the terminal device to the main control device are all forwarded to the main control device by the sub-control device. For the main control device, whether it is an abnormal packet sent by the sub-control device or an abnormal packet sent by the terminal device, the main control device cannot distinguish and can only judge through the business anomaly detection system. If the business anomaly detection system is currently set to send the abnormal packet by the sub-control device, then the source of the abnormality must be on the sub-control device. If the business anomaly detection system is currently set to send the abnormal packet by the terminal device, then the source of the abnormality must be on the terminal device.

[0154] The business anomaly detection system sets the master device to send an abnormal packet (for example, when starting a meeting, the master device notifies the terminal that the meeting entry packet is lost or abnormal):

[0155] Packet loss on the master device: The master device starts the conference service and the conference status is in progress. At this time, the master device notifies the terminal that the conference joining packet is lost, and all terminals fail to join the conference.

[0156] The master device sends duplicate packets, tampered packets, and damaged packets: the sub-control device will forward the abnormal packets sent by the master device to the terminal device. The processing process of the terminal device after receiving the abnormal packet is the same as the above processing process, which will not be repeated here.

[0157] The embodiments of the present invention conduct comprehensive detection on the devices in the visual network under abnormal scenarios such as simulated service packet loss, service duplication, service tampering, and service damage, so as to timely discover and solve problems, so that normal services can be carried out when such abnormal situations occur during the visual network service process, thereby ensuring the stable operation of the visual network service.
