本发明涉及网络安全技术领域，特别涉及一种网络节点设备及其主从配置方法和系统。The invention relates to the technical field of network security, in particular to a network node device and a master-slave configuration method and system thereof.
背景技术Background technique
随着网络应用的复杂化，一些网络的关键节点承载了大量的业务。如果这些关键的网络节点出现问题，那么可能会导致与其连接的各个节点的业务无法正常进行。为了保证网络节点的高可靠性，通常的做法是使用双机设备，即在一个节点同时配置两套网络设备，其中一个是主设备，另外一个是从设备。当主设备出现问题时，可以切换到从设备，由从设备代替主设备进行网络通信，而不会导致业务的中断，从而提供了一种保证网络可靠性的方法。由于接入的两台设备在软件和硬件上是完全一样的，因此必须要有个方法来确定，哪台设备是主设备，哪台设备是从设备。With the complexity of network applications, some key nodes of the network carry a large number of services. If there is a problem with these key network nodes, the business of each node connected to it may not be able to proceed normally. In order to ensure the high reliability of network nodes, the usual practice is to use dual-machine devices, that is, to configure two sets of network devices on one node at the same time, one of which is the master device and the other is the slave device. When there is a problem with the master device, it can be switched to the slave device, and the slave device replaces the master device for network communication without causing service interruption, thus providing a method to ensure network reliability. Since the two connected devices are exactly the same in software and hardware, there must be a way to determine which device is the master device and which device is the slave device.
现有技术中，通常是通过设备间的交互通信解决来决定设备是主设备还是从设备，在两台设备的启动过程中，两台设备通过复杂的协议，通过复杂的算法最终区分出主从关系,或者通过连续更换设备等频繁操作，效率很低，实现起来比较复杂，同时也增加了系统重要数据丢失或者异常的概率，增加了维护的工作量和难度。In the prior art, it is usually determined whether the device is the master device or the slave device through the interactive communication between the devices. During the startup process of the two devices, the two devices finally distinguish the master device from the master device through a complex protocol and a complex algorithm. relationship, or through frequent operations such as continuous replacement of equipment, the efficiency is very low, and it is more complicated to implement. At the same time, it also increases the probability of important system data loss or abnormality, and increases the workload and difficulty of maintenance.

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，下面结合附图对本发明作进一步的详细说明。应该理解，这些描述只是示例性的，而并非要限制本发明的范围。此外，在以下说明中，省略了对公知结构和技术的描述，以避免不必要地混淆本发明的概念。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.
图1显示了本发明优选实施例的网络节点设备的主从配置方法的流程图。Fig. 1 shows a flowchart of a master-slave configuration method of a network node device in a preferred embodiment of the present invention.
如图1所示，本实施例的网络节点设备的主从配置方法，用于对网络节点中预先配置为主设备和从设备的两台网络设备进行主从设备的配置，这里，主设备的配置信息预先设置为主设备，从设备的配置信息预先设置为从设备，所述方法包括如下步骤：As shown in Figure 1, the master-slave configuration method of the network node device in this embodiment is used to configure the master-slave device for two network devices in the network node that are pre-configured as a master device and a slave device. Here, the master device The configuration information is preset as the master device, and the configuration information of the slave device is preset as the slave device, and the method includes the following steps:
步骤S10，某设备启动并向另一设备发送其配置信息。In step S10, a certain device starts up and sends its configuration information to another device.
配置信息表示该设备预先配置的主从配置信息。例如，主设备发出的配置信息是“我的配置是主设备”，从设备发出的配置信息是“我的配置是从设备”。这里所体现的是两台设备的信息交互，信息的交互可以通过以太网报文的方式发送自身的配置信息；其中，所述以太网报文可以使用二层以太网报文，报文格式为“目的地址+源地址+长度”和/或“类型+数据”。The configuration information represents the pre-configured master-slave configuration information of the device. For example, the configuration information sent by the master device is "my configuration is the master device", and the configuration information sent by the slave device is "my configuration is the slave device". What is reflected here is the information exchange between two devices, and the information exchange can send its own configuration information through the Ethernet message; wherein, the Ethernet message can use a layer 2 Ethernet message, and the message format is "Destination Address + Source Address + Length" and/or "Type + Data".
步骤S11，设备在预定时间内接收另一设备发送的信息。In step S11, the device receives information sent by another device within a predetermined time.
设备启动并向另一设备发送其配置信息后，不会立即配置为主设备并接入网络运行，而是先等待预定时间，在该预定时间内接收另一设备发送的信息,并根据信息的接收情况来执行相应的步骤。该预定时间可以根据需要进行设定，例如设定为1秒钟。After the device starts and sends its configuration information to another device, it will not be configured as the master device immediately and connected to the network to run, but wait for a predetermined time, receive the information sent by another device within the predetermined time, and according to the information Receive the situation to perform the corresponding steps. The predetermined time can be set as required, for example, set to 1 second.
步骤S12，如果设备在预定时间内未接收到另一设备发送的信息，则该设备配置为主设备，并向另一设备发送出配置成功信息。Step S12, if the device does not receive the information sent by another device within a predetermined time, the device is configured as a master device, and sends configuration success information to the other device.
如果本端设备在预定时间(例如等待一秒钟)内没有收到另一设备发送过来的配置信息，则表示本端设备首先启动并配置为主设备，接入网络运行，并向另一设备发送该设备配置为主设备的配置成功信息，如果没有收到对端成为从设备的确认消息，那么本端就持续发送该设备配置为主设备的配置成功信息，即不间断的每隔预定时间(例如1毫秒)发送配置成功信息。这里，配置成功信息表示该设备作为主设备成功启动后的配置信息，通常表述为“我是主设备”。If the local device does not receive the configuration information sent by another device within a predetermined time (for example, waiting for one second), it means that the local device is first started and configured as the master device, connected to the network to run, and sends another device Send the configuration success information that the device is configured as the master device. If the confirmation message that the peer end becomes the slave device is not received, the local end will continue to send the configuration success information that the device is configured as the master device, that is, every predetermined time without interruption (for example, 1 millisecond) to send configuration success information. Here, the configuration success information indicates the configuration information after the device is successfully started as the master device, and is usually expressed as "I am the master device".
步骤S13，如果设备在预定时间内接收到另一设备发送的配置成功信息，则配置为从设备。如果另一设备已经成为主设备，那么就会收到该另一设备发送的配置为主设备的配置成功信息，本端设备收到该信息，表示另一设备已经在先启动并配置为主设备运行了。此时，按照时间优先原则，本端设备会配置为从设备，并向另一设备发送配置为从设备的配置成功信息进行确认，并成为从设备。例如，如果主设备启动后在预定时间内收到了从设备发出的配置成功信息“我是主设备”，由于先启动的从设备已经成功配置为主设备，此时由于结果已经确定，因此即使是其预先配置为“从”，那么实际上也是主设备。这时，该主设备会改变配置为从设备，并向另一设备发送“我是从设备”的配置成功信息进行确认，并成为从设备。Step S13, if the device receives configuration success information sent by another device within a predetermined time, it is configured as a slave device. If another device has become the master device, it will receive the successful configuration information sent by the other device to be configured as the master device. The local device receives this information, indicating that the other device has been started first and configured as the master device. It works. At this time, according to the principle of time priority, the local device will be configured as a slave device, and send a configuration success message to the other device to confirm that it is configured as a slave device, and become a slave device. For example, if the master device receives the configuration success message "I am the master device" from the slave device within a predetermined time after startup, since the slave device started first has been successfully configured as the master device, the result has been determined at this time, so even the It is pre-configured as a "slave", so it is actually a master device. At this time, the master device will change the configuration to be a slave device, and send a configuration success message of "I am a slave device" to another device for confirmation, and become a slave device.
步骤S14，如果设备在预定时间内接收到另一设备发送的配置信息，则根据该设备的配置信息进行主从配置。Step S14, if the device receives the configuration information sent by another device within a predetermined time, perform master-slave configuration according to the configuration information of the device.
上述步骤中，所述发送配置信息、发送配置成功信息及确认信息，均可以通过以太网报文的方式进行发送，其中，所述以太网报文使用的是二层的以太网报文，报文格式为“目的地址+源地址+长度”和/或“类型+数据”。In the above steps, the sending configuration information, the sending configuration success information and the confirmation information can all be sent in the form of Ethernet messages, wherein the Ethernet messages use a layer-2 Ethernet message, and the message The text format is "destination address + source address + length" and/or "type + data".
图2显示了图1中步骤S14的子流程图。FIG. 2 shows a sub-flow chart of step S14 in FIG. 1 .
如图2所示，图1中所示的步骤S14具体包括如下步骤：As shown in Figure 2, step S14 shown in Figure 1 specifically includes the following steps:
步骤S141,设备在预定时间内接收到另一设备发送的配置信息。Step S141, the device receives configuration information sent by another device within a predetermined time.
如果设备在预定时间内接收到另一设备发送的配置信息，则表示对端设备还没有成功配置为主设备。此时，对端设备也会收到本端设备发出的配置信息，即双方都收到了对端的配置信息。这种情况下，表示两台设备在同时竞争成为主设备。If the device receives the configuration information sent by another device within the predetermined time, it means that the peer device has not been successfully configured as the master device. At this time, the peer device will also receive the configuration information sent by the local device, that is, both parties have received the configuration information of the peer. In this case, it means that two devices are competing to become the master device at the same time.
步骤S142，本设备和另一设备根据各自预先设置的配置信息进行主从配置。In step S142, the device and the other device perform master-slave configuration according to their preset configuration information.
本步骤中，根据预先设置的主从配置信息来配置主设备和从设备，预先配置为主设备的设备成功配置为主设备，预先配置为从设备的设备相应的配置为从设备。In this step, the master device and the slave device are configured according to the pre-set master-slave configuration information. The device pre-configured as the master device is successfully configured as the master device, and the device pre-configured as the slave device is correspondingly configured as the slave device.
例如，如果本端设备的配置信息为“我的配置是主设备”，则配置为主设备，并向另一设备(对端设备)发出“我是主设备”的配置成功信息。另一方面，对端设备的配置信息相应的为“我的配置是从设备”，则该对端设备根据其预设的配置信息配置为从设备，并向本端设备发出“我是从设备”的配置成功信息。For example, if the configuration information of the local device is "my configuration is the master device", configure it as the master device, and send a configuration success message of "I am the master device" to the other device (peer device). On the other hand, if the configuration information of the peer device is correspondingly "My configuration is a slave device", then the peer device is configured as a slave device according to its preset configuration information, and sends "I am a slave device" to the local device. " configuration success message.
本步骤中，可以根据预先设置的主从配置信息来配置主设备和从设备。也即，预先配置为主设备的设备会成功配置为主设备，接入网络运行，而预先配置为从设备的设备会相应的配置为从设备，仅仅热机备用。这里，可以在两台设备启动前，预先设置两台设备的主从配置信息，其中一台设备预先设置为主设备，另一台设备预先设置为从设备。In this step, the master device and the slave device may be configured according to preset master-slave configuration information. That is to say, the device that is pre-configured as the master device will be successfully configured as the master device and connected to the network to run, while the device that is pre-configured as the slave device will be correspondingly configured as the slave device, and it will only be hot-started for standby. Here, before the two devices are started, the master-slave configuration information of the two devices can be preset, one of the devices is preset as the master device, and the other device is preset as the slave device.
步骤S143，本设备和另一设备相互发送配置成功信息。In step S143, the device and the other device send configuration success information to each other.
主设备发送该设备配置为主设备的配置成功信息给对端，并成为主设备；对端收到消息后，发送该设备配置为从设备的配置成功信息进行确认，并成为从设备。The master device sends the configuration success information that the device is configured as a master device to the peer end, and becomes the master device; after receiving the message, the peer end sends a configuration success message that the device is configured as a slave device for confirmation, and becomes a slave device.
在成功配置一个设备配置是主，一个设备配置是从后，配置为主的设备发送该设备配置为主设备的配置成功信息给对端，如发送“我是主设备”给对端，并成为主设备；对端收到消息后，也就是此时配置为从的设备，该设备配置为从设备的配置成功信息进行确认，如发送“我是从设备”进行确认，并成为从设备。After successfully configuring a device as the master and a device as the slave, the device configured as the master sends the successful configuration information of the device as the master to the peer, such as sending "I am the master" to the peer, and becomes Master device; after the peer end receives the message, that is, the device configured as a slave device at this time, the device is configured as a slave device to confirm the configuration success information, such as sending "I am a slave device" to confirm and become a slave device.
本实施例通过对设备进行预配置的方式快速的解决主从关系的确定问题，具体的：两台设备都有预配置，一台预配置为主设备，一台预配置为从设备。两台设备启动时，由于概率原因，若两台设备启动时间不一致，导致后起来的设备在开始主备竞争时，先启动的设备已经是主设备，此时由于结果已经确定，因此，如果先启动的是预配置为从设备的设备，也会被确定为主设备，也就是说，即使是预配置为从设备，那么实际上也可能是主设备。若两台设备同时启动，则交互预配置的主备信息，这样就可以快速的判断出主从关系。简单来说，如果已经竞争出主从关系，那么就保持现状，如果没有竞争出，那么一切以预配置为准。This embodiment quickly solves the problem of determining the master-slave relationship by pre-configuring the devices. Specifically, two devices are pre-configured, one is pre-configured as the master device, and the other is pre-configured as the slave device. When two devices are started, due to probability reasons, if the start time of the two devices is inconsistent, when the device that starts up later starts the master-standby competition, the device that starts first is already the master device. At this time, the result has been determined, so if the first A device that is pre-configured as a slave device that is started will also be determined as a master device, that is, even if it is pre-configured as a slave device, it may actually be a master device. If the two devices start at the same time, they will exchange pre-configured master and backup information, so that the master-slave relationship can be quickly judged. To put it simply, if the master-slave relationship has been competed for, then keep the status quo; if not, then everything is subject to pre-configuration.
本实施例通过两台设备双向通信告知的方式确认出主从设备，减少了单向竞争所采取复杂算法的繁琐计算判断，简单易行，极大减小了系统重要数据丢失或者异常的概率，减轻了维护的工作量和难度。In this embodiment, the master-slave device is confirmed through two-way communication notification between two devices, which reduces the cumbersome calculation and judgment of complex algorithms adopted in one-way competition, is simple and easy to implement, and greatly reduces the probability of important data loss or abnormality in the system. The workload and difficulty of maintenance are reduced.
本发明还提供了一种网络节点设备。The invention also provides a network node device.

发送模块11用于接收配置模块13的指令以向外部设备发送信息。例如，设备启动并向另一设备发送其配置信息，以及在设备成功配置完成后，向另一个设备发送配置成功信息。The sending module 11 is used to receive instructions from the configuration module 13 to send information to external devices. For example, a device starts up and sends its configuration information to another device, and after the device is successfully configured, sends a configuration success message to another device.
接收模块12用于接收外部设备发送的信息并发送给配置模块13。例如，设备启动后在预定时间内接收另一设备发送的信息，包括另一个设备发出的配置信息或配置成功信息。The receiving module 12 is used to receive the information sent by the external device and send it to the configuration module 13 . For example, after the device is started, it receives information sent by another device within a predetermined time, including configuration information or configuration success information sent by another device.
配置模块13连接到所述发送模块11和接收模块，用于配置设备的主从配置状态并向发送模块发出指令。所述配置模块13预先设置了配置信息，例如“我的配置是主设备”或“我的配置是从设备”。The configuration module 13 is connected to the sending module 11 and the receiving module, and is used for configuring the master-slave configuration state of the device and sending instructions to the sending module. The configuration module 13 presets configuration information, such as "my configuration is a master device" or "my configuration is a slave device".
具体的，在设备启动时，配置模块13向发送模块11发出指令以向另一设备发送其配置信息。在设备成功配置完成后，配置模块13向发送模块11发出指令，向另一个设备发送配置成功信息。Specifically, when the device is started, the configuration module 13 sends an instruction to the sending module 11 to send its configuration information to another device. After the device is successfully configured, the configuration module 13 sends an instruction to the sending module 11 to send configuration success information to another device.
另一方面，设备启动后，如果配置模块13在预定时间内未从接收模块12接收到另一设备发送的信息，则配置模块13将该设备配置为主设备，并通过发送模块11向另一设备发送出配置成功信息。On the other hand, after the device starts, if the configuration module 13 does not receive the information sent by another device within a predetermined time, the configuration module 13 configures the device as a master device, and transmits information to another device through the sending module 11. The device sends a successful configuration message.
如果配置模块13在预定时间内从接收模块12接收到另一设备发送的配置成功信息，则配置模块13将该设备配置为从设备，并通过发送模块11向另一设备发送出配置成功信息。If the configuration module 13 receives configuration success information sent by another device from the receiving module 12 within a predetermined time, the configuration module 13 configures the device as a slave device, and sends configuration success information to another device through the sending module 11 .
如果配置模块13在预定时间内从接收模块12接收到另一设备发送的配置信息，则根据本设备的配置信息，将本设备配置为主设备或从设备，并通过发送模块11向另一设备发送出配置成功信息。If the configuration module 13 receives configuration information sent by another device from the receiving module 12 within a predetermined time, according to the configuration information of the device, the device is configured as a master device or a slave device, and sends a message to another device through the sending module 11. Send out configuration success message.
以上所述的配置信息的发送、配置成功信息的发送以及确认信息的发送，均可以通过以太网报文的方式发送自身的配置信息；其中，所述以太网报文使用的是二层的以太网报文，报文格式为“目的地址+源地址+长度”和/或“类型+数据”。The sending of the above-mentioned configuration information, the sending of the configuration success information and the sending of the confirmation information can all send their own configuration information in the form of Ethernet packets; Network message, the message format is "destination address + source address + length" and/or "type + data".
