具体实施方式detailed description
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
应当理解，此处所描述的具体实施例仅用以解释本发明，仅仅是本发明一部分实施例，而不是全部的实施例，并不用于限定本发明。It should be understood that the specific embodiments described here are only used to explain the present invention, only a part of the embodiments of the present invention, not all the embodiments, and are not intended to limit the present invention.
参照图1，图1是本发明实施例提供的一种巡检控制方法的步骤流程图，该方法执行于协转服务器，该方法包括如下步骤：Referring to Fig. 1, Fig. 1 is a flow chart of the steps of a patrol control method provided by an embodiment of the present invention, the method is executed on the co-transfer server, and the method includes the following steps:
步骤101、接收监控服务发送的巡检业务请求，其中，巡检业务请求为监控服务接收的监控客户端发送的请求。Step 101: Receive the inspection service request sent by the monitoring service, wherein the inspection service request is a request sent by the monitoring client received by the monitoring service.
需要说明的是，视联网的监控管理平台分为前端服务和后端服务，前端服务又名叫唐古拉，负责整体监控目录的展现、监控视频的调取、视联网监控统一管理平台各种配置。后端服务，负责整个视联网中的所有接入的监控设备的统一管理，以及国标(GB/T28181)平台监控系统的对接服务。监控客户端为监控管理平台的前端服务，监控服务(Mserver)为前端服务的其中一个后端服务。It should be noted that the monitoring and management platform of the Internet of Things is divided into front-end services and back-end services. The front-end service is also called Tanggula, which is responsible for the display of the overall monitoring directory, the retrieval of surveillance videos, and various configurations of the unified management platform of the Internet of Things. The back-end service is responsible for the unified management of all connected monitoring devices in the entire video network, as well as the docking service of the national standard (GB/T28181) platform monitoring system. The monitoring client is the front-end service of the monitoring management platform, and the monitoring service (Mserver) is one of the back-end services of the front-end service.
协转服务器又名监控接入服务器，负责将互联网的监控设备(也可以描述为监控资源)和/或第三方国标下级平台的监控设备接入到视联网中，可实现视联网中浏览和控制互联网上的监控设备。The co-transfer server, also known as the monitoring access server, is responsible for connecting the monitoring equipment of the Internet (which can also be described as monitoring resources) and/or the monitoring equipment of the third-party national standard lower-level platform to the Internet of Vision, which can realize browsing and control in the Internet of Vision Surveillance devices on the Internet.
具体的，参照图2，图2为本发明实施例提供的一种巡检控制方法的系统架构图。监控客户端可以接收用户执行的操作指令，从而响应于操作指令向监控服务发送巡检业务请求，监控服务接收到巡检业务请求后，将巡检业务请求发送给协转服务器，相应的，协转服务器接收监控服务发送的巡检业务请求。其中，监控服务可以与监控客户端部署于同一台设备上，也可以部署在不同的设备上。Specifically, refer to FIG. 2 , which is a system architecture diagram of a patrolling control method provided by an embodiment of the present invention. The monitoring client can receive the operation instruction executed by the user, and then send the inspection service request to the monitoring service in response to the operation instruction. After receiving the inspection service request, the monitoring service sends the inspection service request to the co-transfer server. The transfer server receives the inspection service request sent by the monitoring service. Wherein, the monitoring service may be deployed on the same device as the monitoring client, or may be deployed on different devices.
为具体为唐古拉向MServer发送巡检任务，Mserver收到唐古拉发送的巡检任务，直接向协转服务器发送巡检信令。协转服务器收到巡检信令开始针对本服务器挂载的监控设备进行主动巡检。In order to specifically send inspection tasks to MServer for Tanggula, Mserver receives inspection tasks sent by Tanggula and directly sends inspection signaling to the co-transfer server. After receiving the inspection signal, the co-transfer server starts to actively inspect the monitoring equipment mounted on the server.
步骤102、响应于巡检业务请求，根据均衡策略，判断是否需要对目标监控设备执行巡检业务，其中，目标监控设备包括与协转服务器通信连接的各监控设备或部分监控设备。Step 102 : In response to the inspection service request, judge whether to perform the inspection service on the target monitoring device according to the balance strategy, wherein the target monitoring device includes each monitoring device or some monitoring devices that are communicatively connected to the co-translation server.
协转服务器响应于巡检业务请求，并根据均衡策略，判断是否需要对目标监控设备执行巡检业务。其中，目标监控设备可以包括与协转服务器通信连接的各监控设备(即协转服务器下挂载的所有监控设备)，或者，目标监控设备包括协转服务器下挂载的部分监控设备。The co-conversion server responds to the inspection service request, and judges whether the inspection service needs to be performed on the target monitoring device according to the balancing strategy. Wherein, the target monitoring device may include various monitoring devices connected in communication with the co-translation server (that is, all monitoring devices mounted under the co-translation server), or the target monitoring device includes some monitoring devices mounted under the co-translation server.
例如，如果协转服务器在之前对各监控设备执行巡检时，确定各监控设备都处于白名单中，也即各监控设备都处于可用状态的情况下，目标监控设备可用包括各监控设备。如果协转服务器在之前对各监控设备执行巡检时，确定其中的部分监控设备多次处于不可用状态，则将这些监控设备列入黑名单中，则之后协转服务器再次接收到巡检指令后，可以不对列入黑名单的监控设备执行巡检业务，也即目标监控设备只包括除处于黑名单中的监控设备之外的部分监控设备。For example, if the co-transfer server determines that each monitoring device is in the whitelist when performing an inspection on each monitoring device before, that is, when each monitoring device is in an available state, the target monitoring device can include each monitoring device. If the co-transfer server determines that some of the monitoring devices are unavailable for many times when performing inspections on the monitoring devices before, these monitoring devices will be blacklisted, and then the co-transfer server will receive the inspection command again Finally, the inspection service may not be performed on the monitoring equipment included in the blacklist, that is, the target monitoring equipment only includes some monitoring equipment except the monitoring equipment in the blacklist.
或者，例如，协转服务器下挂载的各监控设备例如包括第三方监控系统1的5个监控设备，第三方监控系统2的10个监控设备。如果第三方监控系统1处于离线状态或者协转服务器正在获取第三方监控系统1的监控资源、且第三方监控系统2处于在线状态且不处于黑名单中，则目标监控设备包括第三方监控系统2的10个监控设备。第三方监控系统的监控资源即指通过第三方监控系统接入协转服务器的监控设备的编码信息或者目录信息。由于在第三方监控系统的监控设备的编码信息或者目录信息发生变更的情况下，如果采用之前的编码信息或目录信息调取第三方监控系统的监控设备的视频流，可能存在调流失败或者调取不到视频流的问题，因此，协转服务器需要重新获取第三方监控系统的监控设备的编码信息和目录信息，在重新获取第三方监控系统的监控设备的编码信息和目录信息时，可以不用对第三方监控系统的监控设备进行巡检，从而可以减轻协转服务器的负担。Or, for example, the monitoring devices mounted under the co-conversion server include, for example, 5 monitoring devices of the third-
步骤103、若不需要对目标监控设备执行巡检业务，则禁止对目标监控设备执行巡检业务。
步骤104、若需要对目标监控设备执行巡检业务，则开始对目标监控设备执行巡检业务。
现有技术中，由于协转服务器在收到巡检指令时，立即执行巡检业务，而此时协转服务器有可能并不适合执行巡检任务，例如，协转服务正在执行其他业务，例如在执行调流业务，在执行调流任务的同时执行巡检任务，则会加重协转服务器的负载。也即此种情况下并不适合执行巡检业务。In the prior art, since the co-transfer server immediately executes the patrol service when receiving the patrol command, the co-transfer server may not be suitable for performing the patrol task at this time, for example, the co-transfer service is performing other services, such as When performing traffic adjustment business, performing inspection tasks while performing traffic adjustment tasks will increase the load on the co-transfer server. That is to say, in this case, it is not suitable to perform the inspection service.
本实施例通过根据均衡策略，判断是否需要对目标监控设备执行巡检业务，在不需要对目标监控设备执行巡检业务，则禁止对目标监控设备执行巡检业务，若需要对目标监控设备执行巡检业务，才开始对目标监控设备执行巡检业务，可以避免在不必对目标监控设备执行巡检业务的情况下，仍旧对目标监控设备执行巡检的情况发生，从而对协转服务器造成额外的负担，加重协转服务器的负载的问题，因此本发明实施例可实现在适合协转服务器执行巡检业务时，协转服务器才执行巡检业务，从而可以在一定程度上降低协转服务器的负载。。In this embodiment, according to the balance strategy, it is judged whether the inspection service needs to be performed on the target monitoring device. It is possible to avoid the situation of performing inspection on the target monitoring device without having to perform the inspection service on the target monitoring device, thus causing additional damage to the co-transfer server. Therefore, the embodiment of the present invention can realize that the coordinated conversion server only performs the patrol inspection service when it is suitable for the coordinated conversion server to perform the patrol service, thereby reducing the load of the coordinated conversion server to a certain extent. load. .
可选的，均衡策略可以包括但不限于协转服务器的负载大小是否大于或等于预设阈值、与协转服务器通信连接的监控系统是否在线、以及协转服务器是否处于获取监控系统的资源的状态。Optionally, the balance strategy may include but not limited to whether the load of the co-translation server is greater than or equal to a preset threshold, whether the monitoring system connected to the co-translation server is online, and whether the co-translation server is in the state of obtaining the resources of the monitoring system .
其中的监控系统即指第三方国标下级平台的监控系统。The monitoring system refers to the monitoring system of the lower-level platform of the third-party national standard.
可选的，还可以包括如下步骤：Optionally, the following steps may also be included:
在对目标监控设备执行巡检业务的过程中，根据均衡策略，判断是否需要暂停对目标监控设备执行巡检业务。In the process of executing the inspection service on the target monitoring device, it is determined whether to suspend the inspection service on the target monitoring device according to the balancing strategy.
其中，根据均衡策略，判断是否需要暂停对目标监控设备执行巡检业务可以包括如下情况：Among them, according to the balance strategy, judging whether to suspend the execution of the inspection service on the target monitoring device may include the following situations:
若协转服务器的负载大小大于或等于预设阈值，则需要暂停对目标监控设备执行巡检业务；或者，If the load of the co-transfer server is greater than or equal to the preset threshold, it is necessary to suspend the inspection of the target monitoring device; or,
若与协转服务器通信连接的监控系统离线，则需要暂停对目标监控设备执行巡检业务，其中，目标监控设备包括与离线状态的监控系统连接的监控设备；或者，If the monitoring system connected to the co-transfer server is offline, it is necessary to suspend the inspection service on the target monitoring device, wherein the target monitoring device includes the monitoring device connected to the offline monitoring system; or,
若协转服务器处于获取与协转服务器通信连接的监控系统的监控资源的状态，则需要暂停对目标监控设备执行巡检业务。If the co-translation server is in the state of acquiring the monitoring resources of the monitoring system communicated with the co-translation server, it is necessary to suspend the execution of the inspection service on the target monitoring device.
需要说明的是，例如，在与协转服务器通信连接的监控系统离线的情况下，暂停对目标监控设备执行巡检业务，此时的目标监控设备为与离线的监控系统通信连接的监控设备。It should be noted that, for example, when the monitoring system communicatively connected to the co-translation server is offline, the execution of the inspection service on the target monitoring device is suspended, and the target monitoring device at this time is the monitoring device communicatively connected to the offline monitoring system.
可选的，还包括：Optionally, also include:
在暂停对目标监控设备执行巡检业务的情况下，根据均衡策略，判断是否需要继续对目标监控设备执行巡检业务。In the case of suspending the execution of the inspection service on the target monitoring device, according to the balancing strategy, it is judged whether it is necessary to continue to perform the inspection service on the target monitoring device.
结合上述举例说明，在与协转服务器通信连接的监控系统离线的情况下，暂停对目标监控设备执行巡检业务，此时的目标监控设备为与离线的监控系统通信连接的监控设备。如果后续该监控系统重新上线，且此时的协转服务器的负载大小小于预设阈值、以及协转服务器未处于获取与该监控系统的监控资源的状态，则可以继续对与该监控系统通信连接的监控设备执行巡检业务。In conjunction with the above examples, when the monitoring system connected to the co-transfer server is offline, the patrol inspection service for the target monitoring device is suspended. At this time, the target monitoring device is the monitoring device connected to the offline monitoring system. If the monitoring system goes online again later, and the load of the co-transfer server is less than the preset threshold at this time, and the co-transfer server is not in the state of obtaining the monitoring resources of the monitoring system, the communication connection with the monitoring system can be continued The monitoring equipment performs the inspection service.
或者例如，在协转服务器获取与协转服务器通信连接的监控系统的监控资源完成的情况下，如果此时协转服务器的负载大小小于预设阈值、且该监控系统处于在线状态，则可以继续对该监控系统通信连接的监控设备执行巡检业务。Or for example, when the co-translation server acquires the monitoring resources of the monitoring system connected to the co-translation server, if the load of the co-translation server is less than the preset threshold and the monitoring system is online, you can continue Execute the inspection service on the monitoring equipment connected by communication with the monitoring system.
可选的，步骤102、根据均衡策略，判断是否需要对目标监控设备执行巡检业务可以包括如下步骤：Optionally, step 102, according to the balancing strategy, judging whether to perform inspection service on the target monitoring device may include the following steps:
若协转服务器的负载大小大于或等于预设阈值、与协转服务器通信连接的监控系统离线、以及协转服务器处于获取监控系统的资源的状态中的至少一种情况发生，则不需要对目标监控设备执行巡检业务。If at least one of the situations in which the load of the co-translation server is greater than or equal to the preset threshold, the monitoring system connected to the co-translation server is offline, and the co-translation server is in the state of obtaining the resources of the monitoring system occurs, there is no need to update the target The monitoring equipment performs the inspection service.
也即只要有上述任何一种情况发生，则不需要对目标监控设备执行巡检业务，从而可以减轻协转服务器的负载。That is, as long as any of the above situations occurs, there is no need to perform inspection services on the target monitoring device, thereby reducing the load of the co-transfer server.
可选的，还可以包括：Optionally, can also include:
如图2所示，向监控客户端发送协转服务器的巡检状态信息，以使监控客户端显示巡检状态信息，其中，巡检状态信息包括巡检进行中、巡检暂停、巡检停止。通过协转服务器将巡检状态信息发送给监控客户端，从而可以保证监控客户端和协转服务器对于巡检状态的认知保持一致，从而可以避免例如在协转服务器的巡检状态为停止的情况下，由于监控客户端显示的巡检状态为巡检进行中时，用户点击停止巡检按钮，导致监控客户端向协转服务器发送无效的指令，或者例如在协转服务器的巡检状态为进行中的情况下，监控客户端显示的巡检状态为巡检停止时，用户点击开始巡检按钮，导致监控客户端向协转服务器发送无效的巡检业务请求。As shown in Figure 2, the inspection status information of the co-transfer server is sent to the monitoring client, so that the monitoring client displays the inspection status information, wherein the inspection status information includes inspection in progress, inspection pause, and inspection stop . The patrolling status information is sent to the monitoring client through the coordinating server, so as to ensure that the monitoring client and the coordinating server have the same awareness of the patrolling status, thus avoiding, for example, that the coordinating server’s patrolling status is stopped In some cases, when the inspection status displayed by the monitoring client is inspection in progress, the user clicks the stop inspection button, causing the monitoring client to send an invalid command to the co-transfer server, or for example, when the co-transfer server’s inspection status is In the case of ongoing inspection, when the inspection status displayed by the monitoring client is inspection stop, the user clicks the button to start inspection, which causes the monitoring client to send an invalid inspection service request to the co-transfer server.
需要说明的是，在协转服务器巡检停止后，协转服务器可以每间隔预设时间对目标监控设备执行巡检业务，不需要监控客户端重新向协转服务器发送巡检业务请求。It should be noted that after the co-transfer server stops the inspection, the co-transfer server can perform the inspection service on the target monitoring device at preset intervals, and there is no need for the monitoring client to resend the inspection service request to the co-transfer server.
参照图3，图3为本发明实施例提供的一种巡检控制装置的结构示意图，该装置300可以设置于协转服务器，该装置300包括：Referring to FIG. 3, FIG. 3 is a schematic structural diagram of a patrol control device provided by an embodiment of the present invention. The

If it is necessary to perform inspection services on the target monitoring equipment, the inspection service on the target monitoring equipment can be started, which can avoid the situation that the inspection service is still performed on the target monitoring equipment when there is no need to perform inspection services on the target monitoring equipment. As a result, an additional burden is imposed on the co-translation server, and the problem of the load on the co-translation server is aggravated. Therefore, the embodiment of the present invention can realize that the co-conversion server only performs the patrol inspection service when it is suitable for the co-translation server to perform the patrol service, so that the co-conversion server can execute the patrol service in a certain Minimize the load on the co-rotation server.

为使本领域技术人员更好地理解本发明实施例，以下对视联网进行介绍：In order to enable those skilled in the art to better understand the embodiments of the present invention, the Internet of Things is introduced as follows:
视联网所应用的部分技术如下所述：Some of the technologies applied in the Internet of Things are as follows:
网络技术(Network Technology)Network Technology
视联网的网络技术创新改良了传统以太网(Ethernet)，以面对网络上潜在的巨大视频流量。不同于单纯的网络分组包交换(Packet Switching)或网络电路交换(CircuitSwitching)，视联网技术采用Packet Switching满足Streaming需求。视联网技术具备分组交换的灵活、简单和低价，同时具备电路交换的品质和安全保证，实现了全网交换式虚拟电路，以及数据格式的无缝连接。The network technology innovation of the Internet of View has improved the traditional Ethernet (Ethernet) to face the potentially huge video traffic on the network. Different from pure network packet switching (Packet Switching) or network circuit switching (Circuit Switching), video networking technology uses Packet Switching to meet Streaming requirements. The Internet of Vision technology has the flexibility, simplicity and low price of packet switching, and at the same time has the quality and security guarantee of circuit switching, realizing the seamless connection of switched virtual circuits and data formats throughout the network.
交换技术(Switching Technology)Switching Technology
视联网采用以太网的异步和包交换两个优点，在全兼容的前提下消除了以太网缺陷，具备全网端到端无缝连接，直通用户终端，直接承载IP数据包。用户数据在全网范围内不需任何格式转换。视联网是以太网的更高级形态，是一个实时交换平台，能够实现目前互联网无法实现的全网大规模高清视频实时传输，将众多网络视频应用推向高清化、统一化。Video networking adopts the two advantages of Ethernet asynchronous and packet switching, eliminates the defects of Ethernet under the premise of full compatibility, has end-to-end seamless connection of the whole network, directly connects to user terminals, and directly carries IP data packets. User data does not require any format conversion across the entire network. Video networking is a more advanced form of Ethernet. It is a real-time switching platform, which can realize the real-time transmission of large-scale high-definition video in the whole network that cannot be realized by the Internet at present, and push many network video applications to high-definition and unification.
服务器技术(Server Technology)Server Technology
视联网和统一视频平台上的服务器技术不同于传统意义上的服务器，它的流媒体传输是建立在面向连接的基础上，其数据处理能力与流量、通讯时间无关，单个网络层就能够包含信令及数据传输。对于语音和视频业务来说，视联网和统一视频平台流媒体处理的复杂度比数据处理简单许多，效率比传统服务器大大提高了百倍以上。The server technology on the Internet of View and unified video platform is different from the server in the traditional sense. Its streaming media transmission is based on connection-oriented, and its data processing capability has nothing to do with traffic and communication time. A single network layer can contain information command and data transmission. For voice and video services, the complexity of video streaming and unified video platform streaming media processing is much simpler than data processing, and the efficiency is greatly improved by more than 100 times compared with traditional servers.
储存器技术(Storage Technology)Storage Technology
统一视频平台的超高速储存器技术为了适应超大容量和超大流量的媒体内容而采用了最先进的实时操作系统，将服务器指令中的节目信息映射到具体的硬盘空间，媒体内容不再经过服务器，瞬间直接送达到用户终端，用户等待一般时间小于0.2秒。最优化的扇区分布大大减少了硬盘磁头寻道的机械运动，资源消耗仅占同等级IP互联网的20％，但产生大于传统硬盘阵列3倍的并发流量，综合效率提升10倍以上。The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system in order to adapt to the super-large capacity and super-large-flow media content, and maps the program information in the server command to the specific hard disk space, and the media content no longer passes through the server. It is delivered directly to the user terminal in an instant, and the user generally waits for less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical movement of the hard disk head seeking. The resource consumption is only 20% of the IP Internet of the same level, but the concurrent traffic generated is 3 times larger than that of the traditional hard disk array, and the overall efficiency is increased by more than 10 times.
网络安全技术(Network Security Technology)Network Security Technology
视联网的结构性设计通过每次服务单独许可制、设备与用户数据完全隔离等方式从结构上彻底根除了困扰互联网的网络安全问题，一般不需要杀毒程序、防火墙，杜绝了黑客与病毒的攻击，为用户提供结构性的无忧安全网络。The structural design of the Internet of View completely eradicates the network security problems that plague the Internet through the individual licensing system for each service, complete isolation of equipment and user data, and generally does not require anti-virus programs and firewalls, preventing hackers and virus attacks , to provide users with a structured worry-free security network.
服务创新技术(Service Innovation Technology)Service Innovation Technology
统一视频平台将业务与传输融合在一起，不论是单个用户、私网用户还是一个网络的总合，都不过是一次自动连接。用户终端、机顶盒或PC直接连到统一视频平台，获得丰富多彩的各种形态的多媒体视频服务。统一视频平台采用“菜谱式”配表模式来替代传统的复杂应用编程，可以使用非常少的代码即可实现复杂的应用，实现“无限量”的新业务创新。The unified video platform integrates business and transmission together, whether it is a single user, a private network user or the sum of a network, it is just an automatic connection. User terminals, set-top boxes or PCs are directly connected to the unified video platform to obtain rich and colorful multimedia video services in various forms. The unified video platform adopts the "recipe-style" table matching mode to replace the traditional complex application programming. It can realize complex applications with very little code and realize "unlimited" new business innovations.
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。Vision networking is a network structure with centralized control. The network can be a tree network, star network, ring network, etc., but on this basis, a centralized control node is required in the network to control the entire network.
如图6所示，视联网分为接入网和城域网两部分。As shown in Figure 6, 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 can be mainly divided into three categories: node servers, access switches, and terminals (including various set-top boxes, encoding boards, memory, etc.). The node server is connected with the access switch, and the access switch can be connected with multiple terminals and can be connected with 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。Wherein, the node server is a node with centralized control function in the access network, which can control the access switches and terminals. The node server can be directly connected to the access switch, and can also 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 devices in the MAN part can also be divided into three categories: MAN servers, node switches, and node servers. The metro server is connected to the node switch, and the node switch can be connected to 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。Wherein, 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 a centralized control function in the metropolitan area network, which can control node switches and node servers. The metro 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 Vision Network is a layered centralized control network structure, while the network controlled by the node server and the metro server can be in various structures such as tree, star, and ring.
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。Vividly speaking, the access network part can form a unified video platform (the part in the dotted circle), and multiple unified video platforms can form a video network; each unified video platform can be interconnected through the metropolitan area and the wide area video network.

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 manual is similar to the definition of labels in MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switching). Assuming that there are two connections between device A and device B, then the data packets from device A to device B have 2 labels, the packet from device B to device A also has 2 labels. The label is divided into an incoming label and an outgoing label. 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 all dominated by the metropolitan area server, and the node switches and node servers are all passively executed. Different from MPLS label allocation, MPLS label allocation 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 packet of the MAN mainly includes the following parts:
DA SA Reserved标签Payload CRCDA SA Reserved Tag Payload CRC
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。That is, destination address (DA), source address (SA), reserved byte (Reserved), label, payload (PDU), and CRC. Among them, the format of the label can refer to the following definition: the label is 32bit, of which the high 16bit is reserved, and only the low 16bit is used, and its position is between the reserved byte of the data packet and the payload.
