视联网的组网如下所述：The networking of the Internet of Things is as follows:
视联网是一种集中控制的网络结构，该网络可以是树型网、星型网、环状网等等类型，但在此基础上网络中需要有集中控制节点来控制整个网络。The Internet of Things is a centralized control network structure. The network can be a tree network, a star network, a ring network, etc., but on this basis, a centralized control node is required in the network to control the entire network.
如图1所示，视联网分为接入网和城域网两部分。As shown in Figure 1, the Internet of Things is divided into two parts: the access network and the metropolitan area network.
接入网部分的设备主要可以分为3类：节点服务器，接入交换机，终端(包括各种机顶盒、编码板、存储器等)。节点服务器与接入交换机相连，接入交换机可以与多个终端相连，并可以连接以太网。The equipment in the access network part can be mainly divided into three categories: node server, access switch, and terminal (including various set-top boxes, coding boards, memory, etc.). The node server is connected to the access switch, and the access switch can be connected to multiple terminals and can be connected to Ethernet.
其中，节点服务器是接入网中起集中控制功能的节点，可控制接入交换机和终端。节点服务器可直接与接入交换机相连，也可以直接与终端相连。The node server is a node in the access network that functions as a centralized control, and can control access switches and terminals. The node server can be directly connected to the access switch, or it can be directly connected to the terminal.
类似的，城域网部分的设备也可以分为3类：城域服务器，节点交换机，节点服务器。城域服务器与节点交换机相连，节点交换机可以与多个节点服务器相连。Similarly, the equipment in the metropolitan area network can also be divided into three categories: metropolitan area server, node switch, and node server. The metropolitan area server is connected with the node switch, and the node switch can be connected with multiple node servers.
其中，节点服务器即为接入网部分的节点服务器，即节点服务器既属于接入网部分，又属于城域网部分。The node server is the node server of the access network part, that is, the node server belongs to both the access network part and the metropolitan area network part.
城域服务器是城域网中起集中控制功能的节点，可控制节点交换机和节点服务器。城域服务器可直接连接节点交换机，也可直接连接节点服务器。The metropolitan area server is a node with centralized control function in the metropolitan area network, which can control the node switch and the node server. The metropolitan area server can be directly connected to the node switch or directly connected to the node server.
由此可见，整个视联网络是一种分层集中控制的网络结构，而节点服务器和城域服务器下控制的网络可以是树型、星型、环状等各种结构。It can be seen that the entire VisionLink network is a network structure controlled by layers and centralized, and the network controlled by the node server and the metro server can be tree, star, ring and other structures.
形象地称，接入网部分可以组成统一视频平台(虚线圈中部分)，多个统一视频平台可以组成视联网；每个统一视频平台可以通过城域以及广域视联网互联互通。Figuratively, the access network part can form a unified video platform (the part in the dashed circle), and multiple unified video platforms can form a video network; each unified video platform can be interconnected through the metro and wide-area video networks.

2.1接入网数据包定义2.1 Definition of Access Network Data Packets
接入网的数据包主要包括以下几部分：目的地址(DA)、源地址(SA)、保留字节、payload(PDU)、CRC。The data packet of the access network mainly includes the following parts: destination address (DA), source address (SA), reserved bytes, payload (PDU), and CRC.
如下表所示，接入网的数据包主要包括以下几部分：As shown in the table below, the data packets of the access network mainly include the following parts:
其中：in:
目的地址(DA)由8个字节(byte)组成，第一个字节表示数据包的类型(例如各种协议包、组播数据包、单播数据包等)，最多有256种可能，第二字节到第六字节为城域网地址，第七、第八字节为接入网地址；The destination address (DA) consists of 8 bytes (byte), the first byte indicates the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are up to 256 possibilities, The second to sixth bytes are the metropolitan area network address, and the seventh and eighth bytes are the access network address;
源地址(SA)也是由8个字节(byte)组成，定义与目的地址(DA)相同；The source address (SA) is also composed of 8 bytes (byte), and the definition is the same as the destination address (DA);
保留字节由2个字节组成；Reserved bytes consist of 2 bytes;

If it is a variety of protocol packets, it is 64 bytes. If it is a single multicast data packet, it is 32+1024=1056 bytes. Of course, it is not limited to Above 2 kinds;
CRC有4个字节组成，其计算方法遵循标准的以太网CRC算法。The CRC consists of 4 bytes, and its calculation method follows the standard Ethernet CRC algorithm.
2.2城域网数据包定义2.2 MAN Data Packet Definition
城域网的拓扑是图型，两个设备之间可能有2种、甚至2种以上的连接，即节点交换机和节点服务器、节点交换机和节点交换机、节点交换机和节点服务器之间都可能超过2种连接。但是，城域网设备的城域网地址却是唯一的，为了精确描述城域网设备之间的连接关系，在本发明实施例中引入参数：标签，来唯一描述一个城域网设备。The topology of the metropolitan area network is a graph. There may be two or even more than two connections between two devices, that is, there may be more than two connections between node switches and node servers, between node switches and node switches, and between node switches and node servers. kind of connection. However, the metropolitan area network address of the metropolitan area network equipment is unique. In order to accurately describe the connection relationship between the metropolitan area network equipment, a parameter: label is introduced in the embodiment of the present invention to uniquely describe a metropolitan area network equipment.
本说明书中标签的定义和MPLS(Multi-Protocol Label Switch，多协议标签交换)的标签的定义类似，假设设备A和设备B之间有两个连接，那么数据包从设备A到设备B就有2个标签，数据包从设备B到设备A也有2个标签。标签分入标签、出标签，假设数据包进入设备A的标签(入标签)是0x0000，这个数据包离开设备A时的标签(出标签)可能就变成了0x0001。城域网的入网流程是集中控制下的入网过程，也就意味着城域网的地址分配、标签分配都是由城域服务器主导的，节点交换机、节点服务器都是被动的执行而已，这一点与MPLS的标签分配是不同的，MPLS的标签分配是交换机、服务器互相协商的结果。The definition of labels in this specification is similar to the definition of MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switch) labels. Assuming that there are two connections between device A and device B, the data packets from device A to device B have 2 labels, packets from device B to device A also have 2 labels. Labels are divided into incoming labels and outgoing labels. Assuming that the label (incoming label) of the data packet entering device A is 0x0000, the label (outgoing label) of the data packet when it leaves device A may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, which means that the address allocation and label allocation of the metropolitan area network are dominated by the metropolitan area server, and the node switches and node servers are all passively executed. Different from MPLS label assignment, MPLS label assignment is the result of mutual negotiation between switches and servers.
如下表所示，城域网的数据包主要包括以下几部分：As shown in the table below, the data packets of the metropolitan area network mainly include the following parts:
即目的地址(DA)、源地址(SA)、保留字节(Reserved)、标签、payload(PDU)、CRC。其中，标签的格式可以参考如下定义：标签是32bit，其中高16bit保留，只用低16bit，它的位置是在数据包的保留字节和payload之间。Namely destination address (DA), source address (SA), reserved bytes (Reserved), label, payload (PDU), CRC. Among them, the format of the label can refer to the following definition: the label is 32 bits, of which the upper 16 bits are reserved, and only the lower 16 bits are used, and its position is between the reserved bytes of the data packet and the payload.
参考图5，示出了本发明实施例的一种组播链路监测方法。Referring to FIG. 5, a method for monitoring a multicast link according to an embodiment of the present invention is shown.
实施例一的步骤流程图具体可以包括如下步骤：The flowchart of the steps of the first embodiment may specifically include the following steps:
步骤501：自治服务器接收终端设备发送的业务。Step 501: The autonomous server receives the service sent by the terminal device.
本发明实施例提供的组播链路监测方法应用于基于视联网的自治网络中，如图6所示，自治网络包含多层自治云，每层自治云包含至少一个自治云。其中，每个自治云均包含自治服务器，自治服务器是自治云的大脑。The multicast link monitoring method provided by the embodiment of the present invention is applied to an autonomous network based on the Internet of Views. As shown in FIG. 6 , the autonomous network includes multiple layers of autonomous clouds, and each layer of autonomous clouds includes at least one autonomous cloud. Among them, each autonomous cloud contains an autonomous server, and the autonomous server is the brain of the autonomous cloud.
自治网络：自治网络是一种分布式的集中控制网络，在视联网中包括多个按层分布的自治云，即视联网的整体网络结构由多个称为自治云的结构单元互相连接而成，自治云在互相连接时呈现出层级结构。Autonomous network: Autonomous network is a distributed centralized control network, which includes multiple autonomous clouds distributed by layers in the Internet of Things, that is, the overall network structure of Internet of Things is composed of multiple structural units called autonomous clouds. , autonomous clouds present a hierarchical structure when connected to each other.
自治云：自治云是构成视联网的基本结构单元，也是使视联网可以正常运行的最小单元。Autonomous cloud: The autonomous cloud is the basic structural unit that constitutes the Internet of Views, and it is also the smallest unit that enables the Internet of Views to operate normally.
步骤502：根据业务，建立组播链路并确定组播链路信息。Step 502: According to the service, establish a multicast link and determine multicast link information.
自治服务器将组播链路信息转换成与视联网传输协议匹配的格式，转换后的组播链路信息发送至分控服务器和边界路由器。The autonomous server converts the multicast link information into a format matching the video networking transmission protocol, and sends the converted multicast link information to the sub-control server and the border router.
步骤503：将组播链路信息同步至分控服务器或边界路由器。Step 503: Synchronize the multicast link information to the sub-control server or the border router.
分控服务器：自治云中的转发节点。每个自治云中均包含分控服务器，若自治云为单自治则无需设置边界路由器，若自治云为多自治则需设置边界路由器。Sub-control server: the forwarding node in the autonomous cloud. Each autonomous cloud contains sub-control servers. If the autonomous cloud is single-autonomous, you do not need to set up a border router, and if the autonomous cloud is multi-autonomous, you need to set up a border router.
边界路由器：边界路由器是自治云的数据转发节点，可以同时连接到两层自治云中，能够实现跨自治云的数据转发。Border router: The border router is the data forwarding node of the autonomous cloud. It can be connected to two layers of autonomous clouds at the same time, and can realize data forwarding across autonomous clouds.
分控服务器或边界路由器接收到组播链路信息后与自治服务器同步，无论同步成功与否均会返回同步响应结果至自治服务器。其中，同步响应结果即同步响应信息。The sub-control server or the border router synchronizes with the autonomous server after receiving the multicast link information, and returns a synchronization response to the autonomous server regardless of whether the synchronization is successful or not. The synchronization response result is synchronization response information.
步骤504：响应终端设备发送的业务。Step 504: Respond to the service sent by the terminal device.
自治服务器无需等待分控服务器或边界路由器的同步响应结果，直接返回成功至终端设备，这样就保证了自治服务器可以快速的给发起业务的设备发送响应信息，避免影响其它的业务的正常进行，可提升自治的处理性能。The autonomous server does not need to wait for the synchronization response result of the sub-control server or the border router, and directly returns the success to the terminal device, which ensures that the autonomous server can quickly send the response information to the device that initiates the service, so as to avoid affecting the normal operation of other services. Improve autonomous processing performance.
步骤505：开启预设线程处理分控服务器或边界路由器返回的同步响应信息。Step 505: Start a preset thread to process the synchronization response information returned by the sub-control server or the border router.
自治服务器中预设有特定线程，该线程即预设线程用于专门接收分控服务器或边界路由器的组播链路的同步成功与否的响应，如果全部正确，则忽略结果，如果出现同步失败的情况，则把失败信息上报给网管服务器，由网管服务器对组播链路进行修复或断开该链路。A specific thread is preset in the autonomous server. This thread is the preset thread that is used to receive the response of the synchronization success of the multicast link of the sub-control server or the border router. If all are correct, the result will be ignored. If synchronization fails In the case of failure, the failure information is reported to the network management server, and the network management server repairs the multicast link or disconnects the link.
本发明实施例提供的组播链路监测方法，在将组播链路信息同步至分控服务器或边界路由器后便响应终端设备发送的业务；边响应业务边通过开启预设线程处理分控服务器或边界路由器返回的同步响应信息，也即无论同步是否成功均先对终端设备做出业务响应，能够有效缩短响应时间提升响应速度，从而提升终端设备用户的体验。In the multicast link monitoring method provided by the embodiment of the present invention, after synchronizing the multicast link information to the sub-control server or the border router, it responds to the service sent by the terminal device; while responding to the service, the sub-control server is processed by opening a preset thread. Or the synchronization response information returned by the border router, that is, regardless of whether the synchronization is successful or not, the terminal device will first respond to the service, which can effectively shorten the response time and improve the response speed, thereby improving the user experience of the terminal device.

自治服务器中预设有特定线程，该线程即预设线程用于专门接收分控服务器或边界路由器的组播链路的同步成功与否的响应，如果全部正确，则忽略结果，如果出现同步失败的情况，则把失败信息上报给网管服务器，由网管服务器对组播链路进行修复或断开该链路。A specific thread is preset in the autonomous server. This thread is the preset thread that is used to receive the response of the synchronization success of the multicast link of the sub-control server or the border router. If all are correct, the result will be ignored. If synchronization fails In the case of failure, the failure information is reported to the network management server, and the network management server repairs the multicast link or disconnects the link.
步骤606：当同步响应信息指示同步异常时，向网管服务器上报异常信息，以使网管服务器对同步异常生成处理指令。Step 606: When the synchronization response information indicates that the synchronization is abnormal, report the abnormal information to the network management server, so that the network management server generates a processing instruction for the synchronization abnormality.
当同步响应信息指示同步成功时，则不执行后续流程继续处理终端设备的业务。When the synchronization response information indicates that the synchronization is successful, the subsequent process is not executed to continue processing the service of the terminal device.
