[0002] In the multicast system, each multicast source strictly follows the principle of "one multicast source, one address" and is bound to a unique multicast address. If multiple multicast sources send multicast streams to the same address, it will cause resource confusion between different multicast sources.

[0003] However, when a single multicast source sends multicast to a specified multicast address, if any hardware or software failure occurs in the multicast source, the playback service of the single multicast source will be unavailable, resulting in multicast service interruption, which will have an immeasurable impact on the service. Summary of the invention

[0004] The present invention provides a multicast management method, system, electronic device and storage medium, which are used to solve the defect of the service interruption risk caused by the unavailability of a single multicast source playback service in the prior art. By configuring and monitoring when two multicast sources both send multicast streams, when a multicast source fails, it can be seamlessly switched to another multicast source, thereby improving the continuous stability and reliability of the multicast stream transmission service.

[0005] The present invention provides a multicast management method, which is applied to a first multicast source and a second multicast source, wherein both the first multicast source and the second multicast source send multicast streams, and comprises the following steps: Acquire configuration information, where the configuration information includes information that sets the first multicast source as a high-priority node and information that sets the second multicast source as a low-priority node; According to the configuration information, the multicast network port corresponding to the first multicast source is set to be in an activated state and the multicast network port corresponding to the second multicast source is set to be in a closed state, so that the multicast network port corresponding to the first multicast source sends a multicast stream to the shared multicast environment; The running states of the first multicast source and the second multicast source are monitored, so that when the first multicast source fails, the multicast network port corresponding to the second multicast source is switched to send the multicast stream to the shared multicast environment.

[0006] According to a multicast management method provided by the present invention, the operating status includes at least one of a system operating status, a multicast network port status and a multicast outgoing status, the system operating status is used to indicate the working status of the system of the first multicast source and the second multicast source, the multicast network port status is used to indicate the working status of the multicast network ports corresponding to the first multicast source and the second multicast source, and the multicast outgoing status is used to indicate the outgoing status of the multicast stream sent by the first multicast source and the second multicast source.

[0008] According to a multicast management method provided by the present invention, the operating state includes a multicast streaming state, and the monitoring of the operating states of the first multicast source and the second multicast source includes: Sending the multicast stream monitoring data corresponding to the first multicast source and the second multicast source to a service sentinel service, so that the service sentinel service stores the multicast stream monitoring data, wherein the multicast stream monitoring data is determined according to the multicast streams sent by the first multicast source and the second multicast source; Controlling the second multicast source to periodically obtain the multicast stream monitoring data; When the multicast stream monitoring data indicates that an outbound flow state of the multicast stream sent by the first multicast source fails, and an outbound flow state of the multicast stream sent by the second multicast source is normal, the second multicast source is set as a high priority node, and the multicast network port corresponding to the second multicast source is set to be in an activated state, and the multicast network port corresponding to the first multicast source is set to be in a closed state.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the multicast system, the video stream exists in the form of a specific multicast address, for example: udp: / / 239.39.3.150:14053. This address represents a multimedia transmission channel dedicated to this channel, which is used to carry the synchronous transmission of real-time video streams from the multicast source to the receivers of the private network. Through this address, the multicast source uses the efficient UDP protocol to efficiently push video information to many receivers under the same multicast address in a point-to-multipoint manner at one time, which greatly saves network bandwidth resources, realizes low-latency, high-availability multicast services for large-scale concurrent viewing, and provides powerful and robust technical support for large-scale online broadcast activities.

[0025] In the multicast system, each multicast source strictly follows the principle of "one multicast source, one address" and is bound to a unique multicast address. If multiple multicast sources send multicast streams to the same address, it will cause resource confusion between different multicast sources. However, when a single multicast source sends multicast to a specified multicast address, if any hardware or software failure occurs in the multicast source, the playback service of the single multicast source will be unavailable, resulting in multicast service interruption, which will have an immeasurable impact on the service.

[0026] In view of this, an embodiment of the present invention provides a multicast management method, which is applied to a first multicast source and a second multicast source, by obtaining configuration information, the configuration information includes information that the first multicast source is set as a high-priority node and information that the second multicast source is set as a low-priority node; according to the configuration information, the multicast network port corresponding to the first multicast source is set to be in an activated state and the multicast network port corresponding to the second multicast source is set to be in a closed state, so that the multicast network port corresponding to the first multicast source sends a multicast stream to a shared multicast environment; the running status of the first multicast source and the second multicast source is monitored, so that in the event of a failure of the first multicast source, the multicast network port corresponding to the second multicast source is switched to send the multicast stream to the shared multicast environment. This method can improve the continuous stability and reliability of multicast stream transmission services.

[0027] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Figure 1It is a flowchart of the multicast management method provided by the present invention. The multicast management method can be applied to a multicast system, the multicast system includes a first multicast source and a second multicast source, the first multicast source and the second multicast source both send multicast streams, the first multicast source and the second multicast source can be electronic devices, and the electronic devices can be various types of devices with information processing capabilities during implementation. For example, the electronic device can include a personal computer, a laptop computer, a PDA or a server, etc.; the electronic device can also be a mobile terminal, for example, the mobile terminal can include a mobile phone, a car computer, a tablet computer or a projector, etc. Figure 1 As shown, the method may include the following steps 101 to 103: Step 101: Acquire configuration information, where the configuration information includes information for setting the first multicast source as a high-priority node and information for setting the second multicast source as a low-priority node.

[0029] It should be noted that the method for obtaining the configuration may be configuration information input by a user, transmitted by other devices, or pre-stored information. The present invention does not limit the method for obtaining the configuration information. The first multicast source and the second multicast source are set with different priorities, and when performing multicast, a high-priority node may be used for multicasting first, thereby avoiding conflicts between multicast sources and waste of resources.

[0030] Exemplarily, the first multicast source may be installed with a main service, which is responsible for managing the multicast service of the first multicast source. The main service may be a program based on the exchange mechanism software Keepalived. The first multicast server is given a carefully customized initial state through the main service, aiming to always dominate under normal circumstances, including setting the first multicast source as a high-priority node backup. It is understandable that the main service is set as a backup node with a higher priority node (backup), which means that when there is no abnormality in the service, it naturally becomes the master node in the virtual routing group, undertakes the core routing task, and ensures the efficient guidance and transmission of the data flow. The second multicast source may be installed with a backup service, which is responsible for managing the multicast service of the second multicast source. The backup service may be a program based on Keepalived, and the backup service is initialized according to its auxiliary role, aiming to be ready to take over the responsibilities of the main service at any time and respond quickly to failures when necessary. Including setting the second multicast source as a low-priority node backup. It is understandable that the backup service is given a lower priority, which clearly defines its role as a backup node. During the normal operation of the main service, the backup service is on standby, ready to take over when the main service fails.

[0031] Step 102: according to the configuration information, the multicast network port corresponding to the first multicast source is set to be activated and the multicast network port corresponding to the second multicast source is set to be closed, so that the multicast network port corresponding to the first multicast source sends a multicast stream to the shared multicast environment.

[0032] It should be noted that there are many ways to set the multicast network port corresponding to the first multicast source to be in an activated state and the multicast network port corresponding to the second multicast source to be in a closed state according to the configuration information, for example, it can be executed by a control program or by calling other programs. The present invention does not limit the way to set the multicast network port corresponding to the first multicast source to be in an activated state and the multicast network port corresponding to the second multicast source to be in a closed state according to the configuration information. Among them, when the multicast network port corresponding to the first multicast source is in an activated state and the multicast network port corresponding to the second multicast source is set to be in a closed state, the multicast network port corresponding to the first multicast source can send a multicast stream to the shared multicast environment.

[0033] Step 103: Monitor the running status of the first multicast source and the second multicast source, so that when the first multicast source fails, switch to the multicast network port corresponding to the second multicast source to send the multicast stream to the shared multicast environment.

[0034] It should be noted that there are many ways to monitor the operating status of the first multicast source and the second multicast source, for example, the operating status can be obtained by monitoring the operating status through a monitoring program, or the operating status can be obtained by analyzing the operating status through a data analysis program, etc. The present invention does not limit the way to monitor the operating status of the first multicast source and the second multicast source.

[0035] In addition, when the operating status indicates that the first multicast source has failed, there are many ways to switch to the multicast network port corresponding to the second multicast source to send the multicast stream to the shared multicast environment, such as controlling the switching by a control program, etc. The present invention does not limit the way to switch to the multicast network port corresponding to the second multicast source to send the multicast stream to the shared multicast environment.

[0036] Exemplarily, the multicast network port control program may be used to set the multicast network port corresponding to the first multicast source to be closed, and to set the multicast network port corresponding to the second multicast source to be activated.

[0037] The method provided by the present invention builds a high-availability service for the outflow of the main and backup multicast sources, and at the same time sets the corresponding functions according to the agreement. The main multicast source is a high-priority node backup node, and the backup outflow service is a low-priority node backup node. A set of high-availability management methods suitable for dual multicast source systems is constructed. Under normal circumstances, the first multicast source provides multicast services. When the first main multicast source encounters hardware failures, software anomalies, etc., the multicast service can be seamlessly switched to the backup multicast source to maintain the continuous operation of the system. Among them, both the main and backup servers run the multicast sending program to send multicast streams, and use multicast technology to efficiently transmit information to the shared shared multicast environment. Among them, the multicast network port of the main server (the first multicast source) is in an activated state, and continues to send data stably to the shared multicast environment; while the backup server (the second multicast source) strategically closes its multicast network port to avoid conflicts with the main server or waste of resources.

[0038] In some embodiments, to ensure that the multicast services of the two servers are always in good operating condition, the system synchronously deploys and enables a set of strict monitoring programs to monitor the operating status and multicast service performance of the primary and backup servers in real time, ensure the overall robustness and stability of the high-availability system, and avoid unnecessary switching under abnormal conditions.

[0039] In an embodiment of the present invention, the operating status includes at least one of a system operating status, a multicast network port status, and a multicast outbound flow status. The system operating status is used to indicate the working status of the system of the first multicast source and the second multicast source. The multicast network port status is used to indicate the working status of the multicast network port corresponding to the first multicast source and the second multicast source. The multicast outbound flow status is used to indicate the outbound flow status of the multicast stream sent by the first multicast source and the second multicast source.

[0040] It can be understood that by monitoring at least one of the multicast system status, multicast network port status and multicast outflow status of the multicast of the first multicast source and the second multicast source, the accurate operating status corresponding to the multicast of the first multicast source and the second multicast source can be obtained, thereby improving the accuracy of status monitoring.

[0041] In some embodiments, the multicast system status and the multicast network port status may be monitored simultaneously, and whether to perform multicast network port switching may be determined according to the system operation status and the multicast network port status.

[0042] Figure 2 FIG. 1 is one of the flow charts of the method for monitoring the operating status provided by the present invention. Figure 2 As shown, the running state includes the system running state and the multicast network port state, the first multicast source and the second multicast source constitute a virtual routing group, and the monitoring of the running state of the first multicast source and the second multicast source may include: Step 201: When it is monitored that the first multicast source is running normally, a heartbeat message is periodically sent to the second multicast source through the virtual routing group; Step 202: When a multicast system of the first multicast source fails or a multicast network port corresponding to the first multicast source is monitored to fail, stop sending the heartbeat message to the second multicast source and set the first multicast source as a low priority node; Step 203: When it is monitored that the second multicast source has not received the heartbeat message, the second multicast source is set as a high priority node, the multicast network port corresponding to the second multicast source is set to be activated, and the multicast network port corresponding to the first multicast source is set to be closed.

[0043] It should be noted that the method in which the first multicast source sends a heartbeat message to the second multicast source when operating normally, stops sending heartbeat messages when the first multicast source operates normally, and the second multicast source determines whether to switch the multicast network port based on whether the heartbeat message is received can ensure the continuity and low interruption time of the multicast service.

[0044] The heartbeat message may be a heartbeat message based on Virtual Router Redundancy Protocol (VRRP).

[0045] Furthermore, setting the second multicast source as a high priority node, setting the multicast network port corresponding to the second multicast source in an activated state, and setting the multicast network port corresponding to the first multicast source in a closed state may include: setting the second multicast source as a high priority node, and calling a notification program; calling a multicast network port control program through the notification program, so that the multicast network port control program sets the multicast network port corresponding to the first multicast source in a closed state and sets the multicast network port corresponding to the second multicast source in an activated state.

[0046] It should be noted that a virtual routing group can be composed of a pair of active and standby services, both of which can work together to build a robust and efficient virtualized routing environment based on Keepalived technology. The active and standby services follow their own specific configuration principles at the beginning of the design to achieve accurate role positioning, fault detection and smooth switching, ensuring the continuous and stable operation of network services.

[0047] In addition, the present invention can use a multicast network port control program to realize the opening and closing and the opening and closing switching of the corresponding multicast network ports of the first multicast source and the second multicast source. The multicast network port control program can log in to a specific switch and manipulate the opening and closing of the corresponding multicast network port. When encountering a fault situation, it can quickly close the multicast network port of the faulty device and synchronously activate the multicast network port of the multicast source that has been promoted to the host role, thereby ensuring that the multicast service can continue seamlessly after the failover, providing users with uninterrupted high-quality services.

[0048] It is understandable that the second multicast source in the present invention operates in preemptive mode. Once the current master node is detected to have a fault, the preemption process will be started immediately, and the method of actively promoting to a new master node can ensure the continuity and low interruption time of the routing service. In addition, the first multicast source operates in non-preemptive mode, that is, after encountering a fault that causes the role to be downgraded to a backup machine, it will not actively try to reacquire the master identity unless the root cause of the fault is clearly identified and resolved. This strategy helps to prevent network jitter and resource waste caused by repeated switching for unknown reasons, and ensures that the system remains stable before the problem is completely resolved.

[0049] In addition, the first multicast source is configured to monitor the status of the multicast network port. Once a multicast network port failure is detected, the primary service will quickly trigger the service switching mechanism to ensure that when key network components fail, the routing service can be seamlessly migrated to the backup machine to maintain the connectivity and availability of the overall system. The second multicast source is configured not to track the multicast network port. In other words, considering that the multicast network port is usually closed under normal circumstances, the backup service deliberately does not track the status of such a network port to avoid misjudgment that affects the normal performance of its backup role.

[0050] In some embodiments, the multicast streaming status may be monitored, and whether to perform multicast network port switching may be determined according to the multicast streaming status.

[0051] Figure 3 FIG. 2 is a flow chart of the method for monitoring the operating status provided by the present invention. Figure 3 As shown, the running state includes a multicast streaming state, and the monitoring of the running states of the first multicast source and the second multicast source may include: Step 301: sending multicast stream monitoring data corresponding to the first multicast source and the second multicast source to a service sentinel service, so that the service sentinel service stores the multicast stream monitoring data, wherein the multicast stream monitoring data is determined according to the multicast streams sent by the first multicast source and the second multicast source; Step 302: Control the second multicast source to periodically obtain the multicast stream monitoring data; Step 303: When the multicast stream monitoring data indicates that the outgoing state of the multicast stream sent by the first multicast source fails, and the outgoing state of the multicast stream sent by the second multicast source is normal, the second multicast source is set as a high priority node, and the multicast network port corresponding to the second multicast source is set to be activated, and the multicast network port corresponding to the first multicast source is set to be closed.

[0052] It should be noted that the business sentinel service can be a third-party service independent of the master-standby multicast streaming system. The business sentinel service receives and analyzes the real-time multicast stream monitoring data reported by the first multicast source and the second multicast source. Combined with the operating status of the first multicast source and the second multicast source, it can timely increase the priority of the second multicast source, triggering it to preempt the master role and smoothly switch to the main multicast source, so as to dynamically optimize the system resource configuration and ensure service performance and stability.

[0053] Furthermore, the multicast stream monitoring data includes first outgoing stream data and second outgoing stream data. Before sending the multicast stream monitoring data corresponding to the first multicast source and the second multicast source to the business sentinel service, the method may also include: obtaining first outgoing stream data through the first multicast stream monitoring service, and sending the first outgoing stream data to the business sentinel service, wherein the first outgoing stream data is obtained by monitoring the outgoing stream status of the multicast streaming program corresponding to the first multicast source; obtaining second outgoing stream data through the second multicast stream monitoring service, and sending the second outgoing stream data to the business sentinel service, wherein the second outgoing stream data is obtained by monitoring the outgoing stream status of the multicast streaming program corresponding to the second multicast source.

[0054] It should be noted that the first multicast source and the second multicast source can output multicast streams through the multicast streaming program. Among them, the multicast streaming program can convert traditional unicast format video streams into efficient and reliable multicast formats to meet the needs of large-scale concurrent access. In particular, for the common HLS (HTTP Live Streaming) unicast stream, the program can accurately convert it into a multicast TS (Transport Stream) stream, which significantly improves the distribution efficiency and scalability of streaming media services. The core working mechanism of the multicast streaming program is to parse and utilize the PCR (Program Clock Reference), DTS (Decoding Time Stamp) or PTS (Presentation Time Stamp) timestamps in the original video stream to ensure that the video content is pushed to the multicast network on time and in an orderly manner at a precise time point and at a predetermined frequency.

[0055] In addition, the first multicast source and the second multicast source can monitor the multicast stream through the multicast stream monitoring service (the first multicast stream monitoring service and the second multicast stream monitoring service). The multicast stream monitoring service monitors the outgoing stream status of the "multicast streaming program" to timely discover and handle any abnormal situation.

[0056] The first multicast stream monitoring service and the second multicast stream monitoring service monitor the outgoing stream service status of the first multicast source and the second multicast source respectively, and report to the service sentinel service. The second multicast source decides whether to update the current node priority according to the service sentinel service result.

[0057] Exemplarily, the running state of the main service corresponding to the first multicast source in the present invention is independent of the monitoring program (multicast stream monitoring service and business sentinel service), and even if the monitoring program finds a problem, it will not trigger meaningless service switching. This is intended to prevent invalid switching due to misjudgment when both the first multicast source and the second multicast source may fail, and further enhance the robustness of the system. The backup service corresponding to the second multicast source is closely dependent on the status information provided by the monitoring program. Once the monitoring program detects a master node failure, the backup service will respond immediately and promote itself to a master node according to the preset process, filling the gap left by the failure of the main service in time to ensure the uninterrupted operation of the network service.

[0058] In summary, the first multicast source and the second multicast source provided by the present invention can be set through the primary and backup services Keepalived through a fine initial state, which not only realizes the clarity of role division, but also ensures rapid response and smooth switching in the face of various fault scenarios, and jointly builds a highly reliable and self-healing virtual routing group architecture.

[0059] The following describes an exemplary application of an embodiment of the present invention in a practical application scenario.

[0060] Figure 4 It is a schematic diagram of the overall process of a multicast management method provided by the present invention. The virtual routing group can be composed of a pair of master and backup services, both of which are based on Keepalived technology to collaboratively build a robust and efficient virtualized routing environment. The master service (Keepalived-master) and the backup service (Keepalived-backup) follow their own specific configuration principles at the beginning of the design to achieve accurate role positioning, fault detection and smooth switching, and ensure the continuous and stable operation of network services.

[0061] The primary service is given a carefully customized initial state, designed to always dominate under normal circumstances and avoid unnecessary switching under abnormal conditions: the primary service is set as a backup node with a higher priority node, which means that when there is no abnormality in the service, it naturally becomes the master node in the virtual routing group, taking on the core routing task and ensuring the efficient guidance and transmission of data flows. The backup service is initialized according to its auxiliary role, designed to be ready to take over the responsibilities of the primary service at any time and respond quickly to failures when necessary: ​​the backup service is given a lower priority, clearly defining its role as a backup node. During the normal operation of the primary service, the backup service is on standby, ready to take over the work when the primary service fails.

[0062] like Figure 4 As shown, a multicast source high availability method based on a virtual routing redundancy protocol and a system automatic degradation scenario proposed in an embodiment of the present invention are introduced as follows: Scenario 1: The main multicast source server system fails.

[0063] (1) The main multicast source server system fails, and the main service stops sending VRRP heartbeat packets.

[0064] (2) Since the backup multicast source server cannot receive the heartbeat message from the master, the backup service adjusts itself to the master node and calls the notify_master script to notify the master node.

[0065] (3) The notify_master script of the notification node calls the multicast network port interface control program to complete the switchover between the primary and standby network ports, that is, close the network port of the primary node and open the network port of the standby node.

[0066] Scenario 2: The network port of the primary multicast source server fails.

[0067] (1) When the network interface of the primary multicast source server fails, the interface monitoring script track_interface is triggered and enters the FAULT state. The primary service stops sending VRRP heartbeat packets.

[0068] (2) Because the backup multicast source server cannot receive the heartbeat message from the master, the backup service adjusts itself to the master and calls the notify_master script to notify the master node.

[0069] (3) The notify_master script of the master node is notified to call the multicast network port interface control program to complete the switchover between the primary and standby network ports, that is, to close the network port of the master node and open the network port of the standby node.

[0070] Scenario 3: The outgoing streaming program of the primary multicast source service is abnormal.

[0071] (1) The monitoring services on the primary and backup multicast streaming servers periodically report the status of their respective streaming programs.

[0072] (2) The Business Sentinel Service updates and stores the active and standby service status records based on the active and standby status.

[0073] (3) The backup outflow service regularly detects the availability of the primary and backup services through the business sentinel service under the monitoring script track_script event. When the primary service is unavailable but the backup service is available, the backup service increases its priority to be higher than the primary outflow service.

[0074] (4) After the priority is raised, the backup service preempts the VIP, triggering the call of the notify_master script to notify the master node.

[0075] (5) Notify the master node script notify_master to execute the multicast network port control program to complete the multicast network port switching between the master and standby nodes, that is, close the master node network port and open the standby node network port.

[0076] In the above-mentioned embodiment, the multicast management method based on the Virtual Router Redundancy Protocol (VRRP) application effectively avoids the risk of service interruption caused by the failure of a single multicast source server, and ensures the continuous stability and reliability of the multicast streaming transmission service.

[0077] The advantages of the solution adopted in this embodiment include: 1. A high-availability cluster of multicast source outflow service is realized, which solves the business risk caused by the failure of a single multicast source outflow service. 2.
