具体实施方式DETAILED DESCRIPTION
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明中的附图，对本发明中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。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.

为解决相关技术中当视频信令转发网关系统发生故障时，可能直接导致依赖其的所有第三方调用中断，使得视频资源无法被正常访问，不仅会严重影响业务的稳定性，更会降低用户的使用体验，系统可靠性较低的问题，本实施例提出一种视频信令转发网关系统中的节点控制方法、装置、设备及介质，视频信令转发网关系统中包括注册成功的主节点和多个从节点。本实施例可以监测到主节点处于异常状态，则在多个从节点中确定出状态正常的至少一个可用从节点；确定至少一个可用从节点的注册次序，注册次序为相关节点在主节点和多个从节点中的注册成功次序；在至少一个可用从节点的注册次序中确定出最小注册次序；注销主节点，以及将最小注册次序对应的可用从节点设置为新的主节点。本实施例当原主节点失效时，选取出一个可用从节点作为新的主节点并接管原主节点的工作，确保服务的连续性和稳定性，有效提高视频信令转发网关系统的可用性和可靠性。In order to solve the problem that when a video signaling forwarding gateway system fails in the related technology, it may directly cause all third-party calls that rely on it to be interrupted, making the video resources unable to be accessed normally, which will not only seriously affect the stability of the business, but also reduce the user's experience and the problem of low system reliability, this embodiment proposes a node control method, device, equipment and medium in a video signaling forwarding gateway system, and the video signaling forwarding gateway system includes a successfully registered master node and multiple slave nodes. In this embodiment, it can be detected that the master node is in an abnormal state, and at least one available slave node with a normal state is determined among multiple slave nodes; the registration order of at least one available slave node is determined, and the registration order is the order of successful registration of the relevant node in the master node and multiple slave nodes; the minimum registration order is determined in the registration order of at least one available slave node; the master node is deregistered, and the available slave node corresponding to the minimum registration order is set as the new master node. In this embodiment, when the original master node fails, an available slave node is selected as the new master node and takes over the work of the original master node, ensuring the continuity and stability of the service, and effectively improving the availability and reliability of the video signaling forwarding gateway system.
下面结合图1-图4描述本发明的视频信令转发网关系统中的节点控制方法。The node control method in the video signaling forwarding gateway system of the present invention is described below in conjunction with FIG. 1 to FIG. 4 .
如图1所示，本实施例提出第一种视频信令转发网关系统中的节点控制方法，该视频信令转发网关系统中包括注册成功的主节点和多个从节点。该方法包括以下步骤：As shown in FIG1 , this embodiment proposes a first node control method in a video signaling forwarding gateway system, wherein the video signaling forwarding gateway system includes a successfully registered master node and multiple slave nodes. The method includes the following steps:
S101、监测到主节点处于异常状态，则在多个从节点中确定出状态正常的至少一个可用从节点。S101. If it is detected that a master node is in an abnormal state, at least one available slave node in a normal state is determined from among a plurality of slave nodes.
具体的，视频信令转发网关系统为会话初始协议（Session initializationProtocol，SIP）视频信令转发网关系统。Specifically, the video signaling forwarding gateway system is a Session Initialization Protocol (Session initialization Protocol, SIP) video signaling forwarding gateway system.
具体的，视频信令转发网关系统为一个集群架构，由主节点和从节点组成。该系统使用相关协议比如SIP协议来接收、转发、解析和响应视频信令，从而在不同视频监控系统之间建立通信会话的桥梁。主节点作为信令交互的枢纽，负责信令的路由与转发，而不直接参与业务处理。从节点主要负责处理具体的业务请求。外部系统（如外部上级平台）在与视频信令转发网关系统进行通信时，仅需通过主节点这一单一入口点进行交互，而无需深入了解或关注底层从节点的复杂细节。这种高度抽象化的设计可以简化系统间的通信流程，确保外部系统能够以标准化、简化的方式与整个网关集群无缝对接。本实施例的视频信令转发网关系统增强了用户体验，为用户营造一种与单一视频信令网关交互的直观感受，掩盖底层集群架构的复杂性，大大提升系统的易用性和用户满意度。Specifically, the video signaling forwarding gateway system is a cluster architecture, consisting of a master node and a slave node. The system uses relevant protocols such as the SIP protocol to receive, forward, parse and respond to video signaling, thereby establishing a bridge for communication sessions between different video surveillance systems. The master node, as the hub of signaling interaction, is responsible for the routing and forwarding of signaling, but does not directly participate in business processing. The slave node is mainly responsible for processing specific business requests. When an external system (such as an external superior platform) communicates with the video signaling forwarding gateway system, it only needs to interact through the master node, a single entry point, without having to deeply understand or pay attention to the complex details of the underlying slave nodes. This highly abstract design can simplify the communication process between systems and ensure that the external system can seamlessly connect with the entire gateway cluster in a standardized and simplified manner. The video signaling forwarding gateway system of this embodiment enhances the user experience, creates an intuitive feeling of interacting with a single video signaling gateway for users, conceals the complexity of the underlying cluster architecture, and greatly improves the ease of use and user satisfaction of the system.
在实际应用中，当视频信令转发网关系统为SIP视频信令转发网关系统时，视频信令转发网关系统与其他视频系统的互联架构可如图2所示，国标视频系统通过视频网关系统与非国标视频系统实现互联资源共享。视频网关系统中主要包括SIP视频信令转发网关系统和视频流媒体网关系统两部分组成，SIP视频信令转发网关系统用于保证控制指令的准确传递，而视频流媒体网关系统则用于保障视频数据的流畅传输与处理。In practical applications, when the video signaling forwarding gateway system is a SIP video signaling forwarding gateway system, the interconnection architecture between the video signaling forwarding gateway system and other video systems can be shown in Figure 2. The national standard video system realizes interconnection resource sharing with the non-national standard video system through the video gateway system. The video gateway system mainly includes two parts: the SIP video signaling forwarding gateway system and the video streaming gateway system. The SIP video signaling forwarding gateway system is used to ensure the accurate transmission of control instructions, while the video streaming gateway system is used to ensure the smooth transmission and processing of video data.
具体的，本实施例监测主节点的运行状态是否正常，当监测到主节点发生故障或失效时，即启动失效转移机制，寻找可用从节点来替换主节点作为新的主节点进行相关业务处理。Specifically, this embodiment monitors whether the operating status of the master node is normal. When it is detected that the master node fails or fails, the failover mechanism is started to find an available slave node to replace the master node as the new master node to process related services.
具体的，本实施例先行在注册成功的多个从节点中检测出状态正常的至少一个可用从节点。Specifically, this embodiment first detects at least one available slave node in a normal state from multiple slave nodes that have successfully registered.
可以理解的是，可用从节点即为状态正常的从节点。It can be understood that an available slave node is a slave node in a normal state.
S102、确定至少一个可用从节点的注册次序，注册次序为相关节点在主节点和多个从节点中的注册成功次序。S102: Determine a registration order of at least one available slave node, where the registration order is an order in which the relevant node is successfully registered in the master node and multiple slave nodes.
具体的，某个节点（如主节点、可用从节点或不可用从节点）的注册次序即为该节点在所有注册成功的节点中的注册成功次序。Specifically, the registration order of a node (such as a master node, an available slave node, or an unavailable slave node) is the registration success order of the node among all successfully registered nodes.
具体的，本实施例在每个节点注册成功时，确定、设置和保存节点的注册次序。Specifically, this embodiment determines, sets and saves the registration order of each node when each node is successfully registered.
具体的，本实施例确定每个可用从节点的注册次序。Specifically, this embodiment determines the registration order of each available slave node.
可选的，在本实施例提出的其他视频信令转发网关系统中的节点控制方法中，在上述步骤S101之前，方法还包括：Optionally, in another node control method in a video signaling forwarding gateway system proposed in this embodiment, before the above step S101, the method further includes:
根据多个节点的注册成功次序，在多个节点中选取不同的节点设置为主节点和从节点，以及设置主节点和从节点的注册次序。According to the registration success order of the multiple nodes, different nodes are selected from the multiple nodes to be set as the master node and the slave node, and the registration order of the master node and the slave node is set.
可选的，上述根据多个节点的注册成功次序，在多个节点中选取不同的节点设置为主节点和从节点，以及设置主节点和从节点的注册次序，包括：Optionally, the selecting different nodes from the multiple nodes to set as the master node and the slave node according to the order in which the multiple nodes are successfully registered, and setting the registration order of the master node and the slave node, include:
针对第一个注册成功的节点，将节点设置为主节点，将节点的注册次序设置为第一注册次序，以及将第一注册次序保存为当前的最大注册次序；For the first successfully registered node, set the node as the master node, set the node's registration order to the first registration order, and save the first registration order as the current maximum registration order;
针对第二个注册成功的节点，将节点设置为从节点，将当前的最大注册次序加1得到第二注册次序，将从节点的注册次序设置为第二注册次序，并将第二注册次序保存为当前的最大注册次序；For the second successfully registered node, set the node as a slave node, add 1 to the current maximum registration order to get the second registration order, set the registration order of the slave node to the second registration order, and save the second registration order as the current maximum registration order;
针对第三个注册成功的节点，将节点设置为从节点，将当前的最大注册次序加1得到第三注册次序，将从节点的注册次序设置为第三注册次序，直至完成对最新注册成功的节点的注册次序的设置，以及将最新注册成功的节点的注册次序保存为当前的最大注册次序为止。For the third successfully registered node, set the node as a slave node, add 1 to the current maximum registration order to get the third registration order, set the registration order of the slave node to the third registration order, until the registration order of the latest successfully registered node is set, and the registration order of the latest successfully registered node is saved as the current maximum registration order.
可选的，第一注册次序为1。Optionally, the first registration order is 1.
具体的，本实施例将第一个注册成功的节点的注册次序设置为1，并配置为主节点，主要负责与外部系统进行交互、信令转发和路由设定等任务。后续注册成功的节点将按照注册成功的顺序，依次设置节点的注册次序，比如第二个注册成功的节点的注册次序设置为2，第三个注册成功的节点的注册次序设置为3，以此类推。其中，节点的注册次序具体为参数Level值，最新注册成功的节点的Level值由当前的最大Level值加1得到。Specifically, in this embodiment, the registration order of the first successfully registered node is set to 1, and it is configured as the master node, which is mainly responsible for tasks such as interaction with external systems, signaling forwarding, and routing settings. The registration order of subsequent successfully registered nodes will be set in the order of successful registration. For example, the registration order of the second successfully registered node is set to 2, the registration order of the third successfully registered node is set to 3, and so on. The registration order of the node is specifically the parameter Level value, and the Level value of the latest successfully registered node is obtained by adding 1 to the current maximum Level value.
具体的，注册次序大于1的节点均作为从节点，主要负责处理具体的业务请求，如目录查询。从节点根据主节点的路由设定来接收和处理相应的请求，将处理结果返回给主节点，并由主节点转发给外部系统。Specifically, nodes with a registration order greater than 1 are all slave nodes, which are mainly responsible for processing specific business requests, such as directory queries. The slave nodes receive and process the corresponding requests according to the routing settings of the master node, return the processing results to the master node, and the master node forwards them to the external system.
S103、在至少一个可用从节点的注册次序中确定出最小注册次序。S103: Determine a minimum registration order in the registration order of at least one available slave node.
具体的，本实施例在确定出的所有可用从节点的注册次序中确定出最小注册次序，即所有可用从节点中最早注册成功的可用从节点的注册次序。Specifically, this embodiment determines the minimum registration order among the determined registration orders of all available slave nodes, that is, the registration order of the available slave node that successfully registers the earliest among all available slave nodes.
S104、注销主节点，以及将最小注册次序对应的可用从节点设置为新的主节点。S104, deregistering the master node, and setting the available slave node corresponding to the minimum registration order as the new master node.
具体的，本实施例在确定出最小注册次序后，注销主节点，并将最小注册次序对应的可用从节点设置为新的主节点，即将最小注册次序对应的可用从节点替换主节点作为新的主节点，执行主节点职责。Specifically, after determining the minimum registration order, this embodiment cancels the master node and sets the available slave node corresponding to the minimum registration order as the new master node, that is, the available slave node corresponding to the minimum registration order replaces the master node as the new master node to perform the duties of the master node.
可以理解的是，在正常操作中，Level值为1的节点即主节点负责处理所有的信令转发任务。如果该主节点发生故障或失效，视频信令转发网关系统将检测到这一情况，并触发失效转移机制。根据预设的规则，视频信令转发网关系统选择Level值最小的可用从节点即未发生故障的从节点来接管主节点的职责。比如，如果Level值为1的主节点失效，那么Level值2的从节点将成为新的主节点，接管信令转发任务。这个过程会持续进行，视频信令转发网关系统中总有一个节点在负责信令转发，即保持系统中一直有主节点在进行工作，确保服务的连续性和稳定性，有效提高视频信令转发网关系统的可用性和可靠性。It is understandable that in normal operation, the node with a Level value of 1, i.e., the master node, is responsible for handling all signaling forwarding tasks. If the master node fails or fails, the video signaling forwarding gateway system will detect this and trigger the failover mechanism. According to the preset rules, the video signaling forwarding gateway system selects the available slave node with the smallest Level value, i.e., the slave node that has not failed, to take over the responsibilities of the master node. For example, if the master node with a Level value of 1 fails, then the slave node with a Level value of 2 will become the new master node and take over the signaling forwarding task. This process will continue, and there will always be a node in the video signaling forwarding gateway system that is responsible for signaling forwarding, that is, there will always be a master node working in the system to ensure the continuity and stability of the service, and effectively improve the availability and reliability of the video signaling forwarding gateway system.
如图3所示，在本实施例提出的第二种视频信令转发网关系统中的节点控制方法中，包括以下步骤：As shown in FIG3 , the node control method in the second video signaling forwarding gateway system proposed in this embodiment includes the following steps:
S301、流程开始，集群节点注册并获取对应Level值。S301, the process starts, the cluster node registers and obtains the corresponding Level value.
具体的，本实施例在流程开始后，节点注册并在注册成功时，获取对应的Level值即注册次序。Specifically, in this embodiment, after the process starts, the node registers and when the registration is successful, the corresponding Level value, that is, the registration order, is obtained.
S302、判断节点的Level值是否等于1。若是，则执行步骤S3031。否则执行步骤S3032。S302: Determine whether the Level value of the node is equal to 1. If yes, execute step S3031. Otherwise, execute step S3032.
S3031、直接将节点选定为主节点。S3031. Directly select the node as the master node.
S3032、确定该节点为从节点。S3032. Determine that the node is a slave node.
S304、监测各节点运行情况。S304: Monitor the operation status of each node.
S305、监测主节点是否故障。若否，则继续监测各节点运行情况。若是，则执行步骤S306。S305, monitor whether the master node is faulty. If not, continue to monitor the operation of each node. If yes, execute step S306.

S307、选取新的主节点，并返回执行步骤S304。流程结束。S307: Select a new master node and return to step S304. The process ends.
需要说明的是，本实施例基于注册顺序和主节点的失效转移机制，使得视频信令转发网关系统具备高可用性与可靠性。本实施例通过记录节点的注册次序和分配不同的Level值，来确定节点在集群中的优先级和角色。当主节点发生故障时，本实施例根据这些注册次序和Level值，迅速且自动地选择一个新的主节点来接替原主节点的任务。这种机制大大提升了视频信令转发网关系统的容错能力和可靠性，降低了因单点故障而导致的服务中断风险。It should be noted that this embodiment is based on the registration order and the failover mechanism of the master node, so that the video signaling forwarding gateway system has high availability and reliability. This embodiment determines the priority and role of the node in the cluster by recording the registration order of the node and assigning different Level values. When the master node fails, this embodiment quickly and automatically selects a new master node to take over the task of the original master node based on these registration orders and Level values. This mechanism greatly improves the fault tolerance and reliability of the video signaling forwarding gateway system and reduces the risk of service interruption caused by single point failures.
还需要说明的是，视频信令转发网关系统中的多个节点相互备份和冗余，确保在某个节点比如主节点出现故障时，其他节点能够迅速接管其任务，从而保证系统的持续稳定运行。It should also be noted that the multiple nodes in the video signaling forwarding gateway system back up and redundancy each other to ensure that when a node, such as the main node, fails, other nodes can quickly take over its tasks, thereby ensuring the continuous and stable operation of the system.
本实施例提出的视频信令转发网关系统中的节点控制方法，视频信令转发网关系统中包括注册成功的主节点和多个从节点。本实施例监测到主节点处于异常状态，则在多个从节点中确定出状态正常的至少一个可用从节点；确定至少一个可用从节点的注册次序，注册次序为相关节点在主节点和多个从节点中的注册成功次序；在至少一个可用从节点的注册次序中确定出最小注册次序；注销主节点，以及将最小注册次序对应的可用从节点设置为新的主节点。本实施例当原主节点失效时，选取出一个可用从节点作为新的主节点并接管原主节点的工作，确保服务的连续性和稳定性，有效提高视频信令转发网关系统的可用性和可靠性。The node control method in the video signaling forwarding gateway system proposed in this embodiment includes a successfully registered master node and multiple slave nodes in the video signaling forwarding gateway system. In this embodiment, if the master node is detected to be in an abnormal state, at least one available slave node in a normal state is determined among the multiple slave nodes; the registration order of at least one available slave node is determined, and the registration order is the order in which the relevant node is successfully registered among the master node and the multiple slave nodes; the minimum registration order is determined among the registration orders of at least one available slave node; the master node is deregistered, and the available slave node corresponding to the minimum registration order is set as the new master node. In this embodiment, when the original master node fails, an available slave node is selected as the new master node and takes over the work of the original master node, ensuring the continuity and stability of the service, and effectively improving the availability and reliability of the video signaling forwarding gateway system.
相关技术中，视频信令转发网关系统作为视频资源调阅共享场景中的核心组件，其主要职责是接收和转发控制指令。但相关技术中视频信令转发网关系统存在多重挑战：In related technologies, the video signaling forwarding gateway system is the core component in the video resource access and sharing scenario, and its main responsibility is to receive and forward control instructions. However, there are multiple challenges in the video signaling forwarding gateway system in related technologies:
首先，并发性能的瓶颈问题。当海量的第三方请求并发产生时，相关技术中的视频信令转发网关系统往往因其处理能力有限而无法满足这些需求，严重影响了超大规模视频共享业务的流畅进行。First, there is the bottleneck problem of concurrent performance. When a large number of third-party requests are generated concurrently, the video signaling forwarding gateway system in the related technology is often unable to meet these requirements due to its limited processing capacity, which seriously affects the smooth operation of ultra-large-scale video sharing services.
其次，单点故障的风险。若视频信令转发网关系统发生故障，将直接导致依赖其的所有第三方调用中断，使得视频资源无法被正常访问，不仅严重影响了业务的稳定性，更大大降低了用户的使用体验，显然这与高可靠性的业务需求背道而驰。Secondly, there is the risk of single point failure. If the video signaling forwarding gateway system fails, it will directly lead to the interruption of all third-party calls that rely on it, making it impossible to access video resources normally, which not only seriously affects the stability of the business, but also greatly reduces the user experience. Obviously, this runs counter to the business requirements of high reliability.
再者，扩展性能的不足。无论是尝试提升其性能还是增加其容量，都面临着巨大的困难。这种局限性极大地制约了云平台业务随着市场需求的快速增长而扩展的可能性。Furthermore, the lack of scalability. Whether trying to improve its performance or increase its capacity, it faces huge difficulties. This limitation greatly restricts the possibility of cloud platform business to expand with the rapid growth of market demand.
综上，虽然依赖相关技术中视频信令转发网关系统实现视频资源的共享在操作上相对简单，但其所带来的并发性能瓶颈、单点故障风险以及扩展性难题都是不容忽视的。In summary, although it is relatively simple to operate the video signaling forwarding gateway system in related technologies to share video resources, the concurrent performance bottlenecks, single point failure risks and scalability problems it brings cannot be ignored.
基于图1，本实施例提出第二种视频信令转发网关系统中的节点控制方法，该方法在上述将最新注册成功的节点的注册次序保存为当前的最大注册次序为止之后，还包括：Based on FIG. 1 , this embodiment proposes a second node control method in a video signaling forwarding gateway system. After the registration order of the latest successfully registered node is saved as the current maximum registration order, the method further includes:
当接收到从节点扩展指令时，根据从节点扩展指令确定待注册的新从节点，对待注册的新从节点进行注册，确定注册成功，则针对新从节点进行注册次序的设置以及对当前的最大注册次序进行更新；When a slave node extension instruction is received, a new slave node to be registered is determined according to the slave node extension instruction, the new slave node to be registered is registered, and if the registration is successful, a registration order is set for the new slave node and a current maximum registration order is updated;
当接收到从节点注销指令时，根据从节点注销指令在多个从节点中确定待注销的从节点，对待注销的从节点进行注销。When a slave node deregistration instruction is received, a slave node to be deregistered is determined among multiple slave nodes according to the slave node deregistration instruction, and the slave node to be deregistered is deregistered.
本实施例提出的视频信令转发网关系统中的节点控制方法，通过扩展或减少从节点的数量，能够根据实际需求进行快速扩展，轻松应对业务量的增长或减少，且无需对整体架构进行改动，提升视频信令转发网关系统的灵活性和可扩展性。The node control method in the video signaling forwarding gateway system proposed in this embodiment can be quickly expanded according to actual needs by expanding or reducing the number of slave nodes, easily cope with the increase or decrease in business volume, and there is no need to change the overall architecture, thereby improving the flexibility and scalability of the video signaling forwarding gateway system.
基于图1，本实施例提出第三种视频信令转发网关系统中的节点控制方法，该方法中，目标节点为主节点或新的主节点，处于正常状态的目标节点用于：Based on FIG. 1 , this embodiment proposes a third node control method in a video signaling forwarding gateway system, in which the target node is a master node or a new master node, and the target node in a normal state is used to:
接收外部系统发送的业务处理指令，业务处理指令中包括请求内容；Receiving a business processing instruction sent by an external system, wherein the business processing instruction includes request content;
根据业务处理指令生成包括请求内容的新业务处理指令，以及根据负载均衡原则在至少一个可用从节点中确定出目标从节点；Generate a new service processing instruction including request content according to the service processing instruction, and determine a target slave node from at least one available slave node according to a load balancing principle;
将新业务处理指令发送至目标从节点，以使目标从节点：根据新业务处理指令中的请求内容和目标从节点的节点信息，生成响应结果并返回至目标节点，响应结果中包括目标从节点的节点信息；Sending the new service processing instruction to the target slave node, so that the target slave node: generates a response result according to the request content in the new service processing instruction and the node information of the target slave node and returns it to the target node, wherein the response result includes the node information of the target slave node;
在响应结果中删除目标从节点的节点信息并增加目标节点的节点信息，得到修改后响应结果；将修改后响应结果发送至外部系统，以在对外部系统隐藏目标从节点的情况下，为外部系统处理相关业务。The node information of the target slave node is deleted from the response result and the node information of the target node is added to obtain a modified response result; the modified response result is sent to the external system to process related business for the external system while hiding the target slave node from the external system.
其中，请求内容用于指示节点处理相应类型的业务，并返回相应的响应结果。The request content is used to instruct the node to process the corresponding type of business and return the corresponding response result.
可选的，上述处于正常状态的目标节点根据业务处理指令生成新业务处理指令的过程，包括：Optionally, the process of the target node in a normal state generating a new service processing instruction according to the service processing instruction includes:
获取目标节点的统一资源标识符（Uniform Resource Identifier，URI)；Get the Uniform Resource Identifier (URI) of the target node;
在业务处理指令中，创建路由Route头部字段，并将Route头部字段对应的字段值设置为由URI和松散路由参数组合成的组合字段值，以生成新业务处理指令；In the business processing instruction, create a route Route header field, and set the field value corresponding to the Route header field to a combined field value composed of the URI and the loose routing parameters to generate a new business processing instruction;
其中，新业务处理指令中Route头部字段对应的组合字段值，用于指示目标从节点将生成的响应结果返回至目标节点。Among them, the combined field value corresponding to the Route header field in the new business processing instruction is used to instruct the target slave node to return the generated response result to the target node.
可选的，业务处理指令中还包括联系地址Contact字段以及相应的字段值。此时，目标节点在接收到业务处理指令时，先行在Contact字段对应的字段值中增加目标节点的URI，之后再创建Route头部字段以及设置Route头部字段对应的组合字段值，得到新业务指令。Optionally, the business processing instruction also includes a contact address Contact field and a corresponding field value. At this time, when the target node receives the business processing instruction, it first adds the URI of the target node to the field value corresponding to the Contact field, and then creates a Route header field and sets the combined field value corresponding to the Route header field to obtain a new business instruction.
需要说明的是，目标从节点根据新业务指令生成的响应结果中包括上述Contact字段以及对应的字段值，该字段值中包括目标节点的URI。而目标节点根据该响应结果生成的修改后响应结果中同样包括该Contact字段和对应的该字段值。外部系统接收到该修改后响应结果时，可以根据该Contact字段和该字段值中目标节点的URI，确定该修改后响应结果是由目标节点发送的。此时，外部系统无法从修改后响应结果中知晓目标从节点的相关信息，本实施例可以进一步实现对目标从节点的隐藏。It should be noted that the target slave node includes the above-mentioned Contact field and the corresponding field value in the response result generated according to the new business instruction, and the field value includes the URI of the target node. The modified response result generated by the target node according to the response result also includes the Contact field and the corresponding field value. When the external system receives the modified response result, it can determine that the modified response result is sent by the target node based on the Contact field and the URI of the target node in the field value. At this time, the external system cannot know the relevant information of the target slave node from the modified response result, and this embodiment can further achieve the hiding of the target slave node.
如图4所示，在本实施例提出的其他视频信令转发网关系统中的节点控制方法中，包括以下步骤：As shown in FIG. 4 , in another node control method in a video signaling forwarding gateway system proposed in this embodiment, the following steps are included:
S401、流程开始，主节点向外部上级平台注册，建立稳定通信连接。S401, the process starts, the master node registers with the external superior platform and establishes a stable communication connection.
具体的，主节点代表视频信令转发网关系统主动向外部系统注册，建立必要的连接和通信信道。外部系统只需要与视频信令转发网关系统中的主节点进行交互，即可达到与视频信令转发网关系统整个集群通信的目的。Specifically, the master node actively registers with the external system on behalf of the video signaling forwarding gateway system to establish necessary connections and communication channels. The external system only needs to interact with the master node in the video signaling forwarding gateway system to achieve the purpose of communicating with the entire cluster of the video signaling forwarding gateway system.
S402、主节点持续监听指定端口以接收SIP信令。S402: The master node continuously monitors the designated port to receive SIP signaling.
主节点注册成功后，主节点会持续监听指定的端口，以接收来自外部系统的SIP信令即上述业务处理指令，如视频业务处理指令。After the master node is successfully registered, the master node will continue to monitor the specified port to receive SIP signaling from the external system, that is, the above-mentioned business processing instructions, such as video business processing instructions.
S403、外部上级平台向主节点发送SIP信令。S403: The external superior platform sends a SIP signaling to the master node.
其中，视频信令转发网关系统中的从节点不与向外部系统注册。从节点通过集群内部的网络与主节点进行通信。当从节点需要处理来自外部系统的请求或向外部系统发送响应时，会将这些信息发送到主节点，由主节点负责转发给外部系统。外部系统只与主节点建立连接和通信，不知道从节点的存在，通过主节点与整个集群进行交互。The slave nodes in the video signaling forwarding gateway system do not register with the external system. The slave nodes communicate with the master node through the network inside the cluster. When the slave node needs to process a request from the external system or send a response to the external system, it will send this information to the master node, which will be responsible for forwarding it to the external system. The external system only establishes a connection and communication with the master node, is unaware of the existence of the slave node, and interacts with the entire cluster through the master node.
S404、主节点根据负载最轻原则选择合适的目标从节点。S404. The master node selects a suitable target slave node based on the principle of lightest load.
具体的，当外部系统发送SIP信令即上述业务处理指令时，主节点接收SIP信令，并准备进行进一步的处理。主节点根据负载最轻原则，选择一个合适的可用从节点即目标从节点来处理接收到的SIP信令。Specifically, when the external system sends SIP signaling, ie the above-mentioned service processing instruction, the master node receives the SIP signaling and prepares for further processing. The master node selects a suitable available slave node, ie the target slave node, to process the received SIP signaling according to the principle of lightest load.
S405、主节点在SIP信令中修改Contact字段值并增加Route头部字段，得到修改后SIP信令并发送至目标从节点。S405: The master node modifies the Contact field value in the SIP signaling and adds the Route header field, obtains the modified SIP signaling and sends it to the target slave node.
具体的，修改后SIP信令即为修改后响应结果。Specifically, the modified SIP signaling is the modified response result.
其中，主节点增加Route头部字段并转发信令。具体的，主节点将接收到的SIP信令转发给选定的从节点即目标从节点。在转发之前，主节点会在信令中增加一个Route头部字段并设置字段值为主节点URI和修改Contact字段值，这个Route头部字段值指示目标从节点在处理完信令后，必须将处理结果返回给主节点。Among them, the master node adds a Route header field and forwards the signaling. Specifically, the master node forwards the received SIP signaling to the selected slave node, i.e., the target slave node. Before forwarding, the master node adds a Route header field to the signaling and sets the field value to the master node URI and modifies the Contact field value. This Route header field value indicates that the target slave node must return the processing result to the master node after processing the signaling.
S406、从节点根据修改后SIP信令执行呼叫建立、修改或终止等操作，生成响应结果。S406. The slave node performs operations such as call establishment, modification or termination according to the modified SIP signaling and generates a response result.
具体的，目标从节点接收到信令后，进行必要的处理，如呼叫建立、修改或终止等操作。Specifically, after receiving the signaling from the target node, it performs necessary processing, such as call establishment, modification or termination.
S407、从节点将响应结果返回给主节点。S407: The slave node returns the response result to the master node.
需要说明的是，由于Route头部字段的存在，目标从节点被强制将处理结果返回给主节点，而不是直接发送给外部系统。It should be noted that due to the existence of the Route header field, the target slave node is forced to return the processing result to the master node instead of sending it directly to the external system.
S408、主节点接收处理结果并修改响应结果以得到隐藏目标从节点相关信息的修改后响应结果。S408: The master node receives the processing result and modifies the response result to obtain a modified response result that hides the relevant information of the target slave node.
S409、主节点发送修改后响应结果至外部上级平台。流程结束。S409: The master node sends the modified response result to the external superior platform. The process ends.
具体的，主节点接收目标从节点返回的处理结果，并修改其中的Contact字段值，以对外隐藏目标从节点的具体信息，确保外部上级平台只与主节点交互，而不知道背后具体的从节点。主节点将修改后的处理结果转发给外部系统，完成整个SIP信令的响应过程。Specifically, the master node receives the processing result returned by the target slave node and modifies the Contact field value to hide the specific information of the target slave node from the outside, ensuring that the external superior platform only interacts with the master node without knowing the specific slave node behind it. The master node forwards the modified processing result to the external system to complete the entire SIP signaling response process.
下面以INVITE请求为例，描述整个外部系统、主节点和目标从节点间的对话过程。The following takes the INVITE request as an example to describe the entire dialogue process between the external system, the master node and the target slave node.
步骤一、外部上级平台发送INVITE请求到主节点。Step 1: The external superior platform sends an INVITE request to the master node.
外部上级平台（网络地址为192.168.1.100）发送到主节点（网络地址为192.168.1.200）的INVITE请求包括下述信息：The INVITE request sent by the external superior platform (network address is 192.168.1.100) to the master node (network address is 192.168.1.200) includes the following information:

[SDP信息][SDP information]
步骤二、主节点转发INVITE请求到目标从节点。Step 2: The master node forwards the INVITE request to the target slave node.
在转发之前，主节点修改Contact字段值，将自身的URI加入其中，Before forwarding, the master node modifies the Contact field value and adds its own URI to it.
这样得到更新后的Contact字段，它现在包含了主节点的URI，并且保留了原始外部上级平台的URI。为了确保响应能够返回给主节点，添加一个Route头部字段，这个Route头部字段包含了主节点的URI，指示任何响应都应该发送到主节点。This results in an updated Contact field that now contains the URI of the primary node and retains the URI of the original external parent platform. To ensure that the response can be returned to the primary node, a Route header field is added. This Route header field contains the URI of the primary node, indicating that any response should be sent to the primary node.
主节点（192.168.1.200）转发到目标从节点（192.168.1.300）的INVITE请求：The master node (192.168.1.200) forwards the INVITE request to the target slave node (192.168.1.300):

步骤三、目标从节点处理INVITE请求并发送响应到主节点。Step 3: The target slave node processes the INVITE request and sends a response to the master node.
目标从节点收到INVITE请求后，处理请求并准备200 OK响应。由于Route头部字段的存在，目标从节点将响应发送回主节点。After receiving the INVITE request, the target slave node processes the request and prepares a 200 OK response. Due to the presence of the Route header field, the target slave node sends the response back to the master node.
目标从节点（192.168.1.300）发送到主节点（192.168.1.200）的200 OK响应：200 OK response from the target slave node (192.168.1.300) to the master node (192.168.1.200):

步骤四、主节点转发200 OK响应到外部上级平台。Step 4: The master node forwards the 200 OK response to the external superior platform.
主节点收到目标从节点的200 OK响应后，为隐藏目标从节点的信息，主节点将目标接收To头部字段的URI修改为原始请求中的目标地址，同时重新修改联系地址Contact字段值为主节点的URI,确保所有后续的SIP消息都通过主节点进行路由。After the master node receives the 200 OK response from the target slave node, in order to hide the information of the target slave node, the master node modifies the URI of the target receiving To header field to the target address in the original request, and at the same time re-modifies the contact address Contact field value to the URI of the master node, ensuring that all subsequent SIP messages are routed through the master node.
主节点（192.168.1.200）转发到外部上级平台（192.168.1.100）的200 OK响应：The master node (192.168.1.200) forwards the 200 OK response to the external superior platform (192.168.1.100):

需要说明的是，外部上级平台只需与主节点建立连接并进行通信，无需与多个从节点分别建立连接，简化了外部上级平台的接入流程，降低了集成复杂度。本实施例通过重新封装Contact字段、目标接收To头部字段和增加Route头部字段等方式，对外隐藏了从节点的具体信息，增加系统安全性，确保了外部上级平台和从节点之间的通信透明性，外部上级平台只需与主节点交互，无需了解集群内部的复杂细节。It should be noted that the external superior platform only needs to establish a connection with the master node and communicate, and does not need to establish connections with multiple slave nodes respectively, which simplifies the access process of the external superior platform and reduces the complexity of integration. This embodiment hides the specific information of the slave node from the outside by repackaging the Contact field, the target receiving To header field, and adding the Route header field, thereby increasing the security of the system and ensuring the transparency of communication between the external superior platform and the slave node. The external superior platform only needs to interact with the master node and does not need to understand the complex details inside the cluster.
本实施例信令控制与业务处理分离，系统通过主节点和从节点的分工设计，实现了信令控制与业务处理的分离。本实施例通过集群架构和负载均衡机制，可以实现SIP信令的高效转发。主节点能够根据各从节点的负载情况，动态分配信令处理任务，确保每个信令都能得到及时、准确的处理。由于主节点专注于信令的路由和转发，而从节点专注于具体的业务处理，分工明确的设计使得业务处理更加高效、准确。In this embodiment, signaling control is separated from business processing. The system realizes the separation of signaling control and business processing through the division of labor design between the master node and the slave node. In this embodiment, the efficient forwarding of SIP signaling can be realized through the cluster architecture and load balancing mechanism. The master node can dynamically allocate signaling processing tasks according to the load conditions of each slave node to ensure that each signaling can be processed in a timely and accurate manner. Since the master node focuses on the routing and forwarding of signaling, and the slave node focuses on specific business processing, the design with clear division of labor makes business processing more efficient and accurate.
