technical field

The present application relates to the communication field, in particular to a communication method and equipment, and a network access system.

Background technique

In a communication network, a network access system can realize the connection of multiple network devices, which includes: a connected access point (Access point, AP) device and a control device. For example, when the first device is connected to the second device through the network access system, the AP device is connected to the first device, and the control device is connected to the second device. In order to prevent the first device from being unable to communicate with the second device due to a failure of the control device, a "master control device" and a "slave control device" are usually set up in the network access system. Both the master control device and the slave control device are connected to the AP device. to connect to the second device. When the master control device fails, the first device communicates with the second device through the AP device and the slave control device.

In related technologies, when the main control device is working, the main control device and the first device can send their respective device information to each other through the AP device, and according to the Link Aggregation Control Protocol (Link Aggregation Control Protocol, LACP) and the device information of both parties, The LACP link interface on the respective devices is determined, so that the main control device and the first device can communicate through the LACP link interface on the main control device and the LACP link interface on the first device. It should be noted that, during the working process of the master control device, the slave control device will detect whether the master control device fails in real time. When it is determined that the master control device fails, the slave control device and the first device can send their respective device information to each other through the AP device, and determine multiple LACP link interfaces on each device according to the LACP and the device information of both parties, so that the slave The control device and the first device can communicate through multiple LACP link interfaces on the slave control device and multiple LACP link interfaces on the first device.

During the process of determining the LACP link interface on the slave control device, the first device and the second device may still need to communicate, but at this time, since neither the master control device nor the slave control device can forward the communication data, Therefore, communication between the first device and the second device may be interrupted.

As shown in Figure 5, the communication method includes:

Step 501, the master control device establishes a backup channel with the slave control device.

For example, when establishing the communication network as shown in Figure 1, the master control device and the slave control device are respectively connected to the AP device, and the master control device and the slave control device are respectively connected to the second device B, and the master The control device and the slave control device can jointly establish a backup channel between the master control device and the slave control device.

Step 502, the first device sends the LACP parameters of the first device to the master control device.

It should be noted that after the communication network shown in Figure 1 is established, the main control device sends the LACP parameters of the main control device to the first device through the AP device, and the first device sends the first device's LACP parameters to the main control device through the AP device. LACP parameters. The LACP parameters of the main control device include: the system priority of the main control device, the system number of the main control device, the interface priority of each interface in the main control device, and the interface number of each interface in the main control device. The LACP parameters of the first device include: the system priority of the first device, the system number of the first device, the interface priority of each interface in the first device, and the interface number of each interface in the first device. It should be noted that the LACP parameters of the main control device are carried on a Link Aggregation Control Protocol Data Unit (Link Aggregation Control Protocol DataUnit, LACPDU) and sent to the first device, and the LACP parameters of the first device are also carried on one LACPDU and sent to the master control device.

Step 503, the main control device determines the LACP link interface on the main control device according to the LACP, the LACP parameters of the main control device, and the LACP parameters of the first device.

After receiving the LACP parameters of the opposite device, the main control device and the first device can respectively compare the system priority of the main control device with the system priority of the first device. When the master control device and the first device determine that the system priority of the master control device is higher than the system priority of the first device, the master control device and the first device determine that the master control device is the master device and the first device is the slave device . For example, assuming that the system priority of the master control device is 10 and the system priority of the first device is 11, both the master control device and the first device determine that the master control device is the active device and the first device is the passive device.

Further, after determining the master device and the slave device, the master control device and the first device can respectively determine the LACP link interface according to the priority of each interface in the master control device (the master device). First, the main control device and the first device need to determine the preset highest number of active links x (integer greater than or equal to 1), and then, according to the priority of each interface in the main control device, select the link with the highest priority x interfaces, and the x interfaces are used as LACP link interfaces in the main control device. It should be noted that when the main control device is connected to the first device, the multiple interfaces on the main control device correspond to the multiple interfaces on the first device one by one, and the first device determines the x number of ports on the main control device. After the interfaces are the LACP link interfaces in the master control device, the first device uses x interfaces on the first device corresponding to the x interfaces on the master control device as the LACP link interfaces of the first device.

Fig. 6 is a schematic diagram of an interface provided by an embodiment of the present invention. As shown in Fig. 6, the main control device has three interfaces (respectively interface 1.1, interface 1.2 and interface 1.3), and the first device also has three interfaces (respectively are interface 2.1, interface 2.2 and interface 2.3), wherein, interface 1.1 corresponds to interface 2.1, interface 1.2 corresponds to interface 2.2, and interface 1.3 corresponds to interface 2.3. If the preset maximum number of active links x is equal to 2, the main control device screens out interface 1.1 and interface 1.2 as the LACP link interfaces of the main control device, then the first device selects interface 2.1 and interface 2.2 as the LACP link of the first device road interface.

It should be noted that if the determined active device is the first device, the main control device and the first device respectively determine the LACP link interface in the first device according to the preset highest number of active links, and the main control device determines the LACP link interface according to The LACP link interface in the first device determines the LACP interface in the master control device.

Step 504, the main control device communicates with the first device through the LACP link interface on the main control device.

After the main control device determines the LACP link interface on the main control device and the first device determines the LACP link interface on the first device, the main control device uses the LACP link interface on the main control device and the The LACP link interface communicates with the first device. For example, the main control device receives the data that the first device needs to send to the second device, or the main control device sends the data that the second device needs to send to the first device to the first device.

It should be noted that, when the master control device is working normally, the slave control device will not communicate with the first device, so that the first device can only communicate with the master control device.

Step 505, the master control device sends the LACP parameters of the first device to the slave control device through the backup channel.

After each time the master control device receives the LACP parameters of the first device sent by the first device, the master control device sends the LACP parameters of the first device to the slave control device through the backup channel established in step 501 . That is, the master control device backs up the LACP parameters of the first device received by the master control device on the slave control device in real time through the backup channel.

Step 506, the slave control device determines the LACP link interface on the slave control device according to the LACP, the LACP parameters of the slave control device, and the LACP parameters of the first device.

Since in the embodiment of the present invention, the LACP parameters of the master control device are the same as the LACP parameters of the slave control device, the master control device determines the The LACP link interface is the same as the LACP link interface of the slave control device determined by the slave control device according to LACP, the LACP parameter of the slave control device, and the LACP parameter of the first device (for example, the number of the LACP link interface is the same, and the number of the LACP link interface is the same. The priority of the road interface is the same). As shown in Figure 6, the slave control device also has interface 1.1, interface 1.2 and interface 1.3, if the LACP link interface on the master control device determined by the master control device is the interface 1.1 and interface 1.2 on the master control device, then the slave The LACP interfaces determined by the control device are interface 1.1 and interface 1.2 on the slave control device.

Exemplarily, after each time the slave control device receives the LACP parameters of the first device, the slave control device compares the system priority of the slave control device with the system priority of the first device. When the system priority of the slave control device is higher than the system priority of the first device, the slave control device determines that the slave control device is a slave device, and the first device is a slave device. If the slave control device determines that the slave control device is the active device, after determining the master device and the slave device, the slave control device will The highest active link count determines the LACP link interface in the slave control device. It should be noted that if the slave device determined by the slave control device is the first device, the slave control device determines the LACP link interface, and then determine the LACP link interface in the slave control device.

Optionally, in step 505, when the master control device sends the LACP parameters of the first device to the slave control device each time, the master control device can also send priority status information of the first device to the slave control device, the priority The status information is used to indicate whether the system priority of the first device is higher than that of the main control device, that is, indicates whether the first device is the active device among the first device and the main control device. In step 506, the slave control device can refer to the priority status information to determine the first device and the master device among the slave control device. When the priority status information is used to indicate that the system priority of the first device is higher than that of the master control device, the slave control device determines that the first device is the master device. The LACP parameter and the LACP parameter of the first device determine the LACP link interface on the slave control device; when the priority status information is used to indicate that the system priority of the first device is lower than the system priority of the master control device, the slave control device The master control device is determined as the master device, and the slave control device determines the LACP link interface on the slave control device according to the LACP and the LACP parameters of the slave control device. In this way, the slave control device can determine the active end device in the slave control device and the first device without comparing the priority of the slave control device with the priority of the first device, thereby improving the determination of the slave control device by the slave control device. Controls the speed of the device's LACP link interface.

Step 507, when the master control device fails, the slave control device communicates with the first device through the LACP link interface on the slave control device.

It should be noted that the slave control device can also monitor whether the master control device fails in real time, such as periodically sending detection information to the master control device. The device returns a reply message, and the slave control device determines that the current master control device is in a normal working state after receiving the reply message. If the slave control device does not receive reply information for a long time, the slave control device determines that the master control device is currently faulty. When the slave control device detects that the master control device fails, the slave control device communicates with the first device through the LACP link interface on the slave control device that is predetermined (that is, determined in step 506).

Further, in step 502 (that is, when the main control device first determines the LACP link interface with the first device), the first device will send the LACP parameters of the first device to the main control device, so that the main control device obtains LACP parameters of the first device, and send the LACP parameters of the first device to the slave control device through the backup channel. In practical applications, after step 502, the first device can also send the LACP parameters of the first device to the main control device multiple times (for example, periodically multiple times), and send the LACP parameters of the first device to the main control device twice arbitrarily. LACP parameters are the same or different. After receiving the LACP parameters of the first device, the master control device also sends the LACP parameters of the master control device to the first device, so as to implement repeated verification of both parties in communication during the communication process. In this way, the master control device can receive the LACP parameters of the first device multiple times, and send the LACP parameters of the first device to the slave control device through the backup channel multiple times. In step 506, the slave control device determines the LACP link interface on the slave control device after receiving the LACP parameters of the first device each time. An LACP link interface on the device communicates with the first device.

Since the first device connected to the AP device may become another first device after the main control device negotiates with the first device for the first time to determine their respective LACP link interfaces, at this time, the first device received by the main control device The LACP parameters of the device may change, so the slave control device needs to obtain the LACP parameters of the first device multiple times, and determine the LACP link interface on the slave control device multiple times. When the master control device fails, the slave control device communicates with the first device using the last determined LACP link interface on the slave control device to ensure that the slave control device is connected to the current AP device when the master control device fails. The device is able to communicate normally.

In the embodiment of the present invention, before the master control device fails, the slave control device has determined the LACP link interface on the slave control device in real time, and since the LACP parameters of the master control device are the same as the LACP parameters of the slave control device, therefore , the interface number and interface priority of the LACP link interface of the slave control device determined by the slave control device are the same as the interface number and interface priority of the LACP link interface of the master control device determined by the master control device. When the master control device fails, the first device cannot communicate with the master control device, and at this time, the slave control device allows the first device to communicate with the slave control device. During the communication process between the slave control device and the first device, since the LACP parameters of the slave control device are exactly the same as those of the master control device, for the first device, the interface of the LACP link between the master control device and the slave control device It is also exactly the same, therefore, when the master control device fails, the first device can quickly switch from the master control device to the slave control device, thereby realizing lossless transmission of data.

It should be noted that the order of the steps in the method embodiments provided by the embodiments of the present invention can be adjusted appropriately, and the steps can also be increased or decreased according to the situation. Any person familiar with the technical field within the technical scope disclosed in the present invention, Changes that can be easily thought of should be covered within the protection scope of the present invention, and thus will not be repeated here.

When the master control device fails, the slave control device has pre-determined the LACP link interface on the slave control device, and the LACP parameters of the master control device are the same as those of the slave control device, so that the LACP link interface on the master control device The interfaces have the same interface priority and interface number as the LACP link interface determined by the slave control device, and the slave control device determines the LACP link interface for communication between the two without communicating with the first device. Therefore, when the master control device fails, the first device quickly switches from the master control device to the slave control device, reducing the loss of communication data when the master control device fails, and reducing the degree of communication interruption between the first device and the second device .
