Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for switching network devices.

Background

A network device is a physical entity that provides network functionality, and network connectivity is affected by network device failure. Therefore, a dual-computer hot standby technology is usually adopted in a network, each network device is configured with a redundant network device, one is used as a main network device, the other is used as a standby network device, and when the main network device fails, the network device is switched to the standby network device to ensure the connectivity of the network.

The silent dual-computer is one of dual-computer hot standby technologies, and the main network device and the standby network device interact with a heartbeat message through a heartbeat interface, where the heartbeat message includes priority information of the network device that sends the heartbeat message. When the main network device works, except the heartbeat interface, the standby network device closes the network interface for receiving and sending messages with other network devices, cannot receive the messages of other network devices, cannot send the messages to other network devices, and only can interact with the main network device to send the heartbeat messages. The silent dual-computer performs the main-standby switching through the heartbeat message, when the heartbeat message indicates that the priority of the main network equipment is lower than that of the standby network equipment, the network interface of the standby network equipment for receiving and transmitting messages of other network equipment is started, and the standby network equipment is switched to the main network equipment.

The priority information in the heartbeat message is determined according to the interface state of the network device, and if the network interface state of the main network device is normal and the main network device fails to normally receive and transmit the message, the priority information in the heartbeat message cannot indicate the failure of the main network device, so that the master-slave switching cannot be realized in time, and the network connectivity is affected.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The silent dual-computer system comprises a main network device and a standby network device, wherein the main network device and the standby network device interact heartbeat messages through heartbeat interfaces, and the heartbeat messages comprise priority information of the network device which sends the heartbeat messages. The main network equipment receives heartbeat messages sent by the standby network equipment, the heartbeat messages sent by the standby network equipment comprise priority information of the standby network equipment, the main network equipment compares the priority information with the priority information of the standby network equipment, and if the priority of the main network equipment is higher than that of the standby network equipment, switching is not performed; and if the priority of the main network equipment is lower than that of the standby network equipment, switching the main network equipment to the standby network equipment and switching the standby network equipment to the main network equipment.

The priority information in the heartbeat message is determined according to the state of the network interface of the network equipment. For example, for a network device, the initial priority information is 100, the priority information of each network interface is 10, when the network interfaces are all normal, the priority information carried in the heartbeat message of the network device is 100, when there is a network interface failure, 10 is subtracted from the initial priority information, the priority information carried in the heartbeat message is 90, and so on.

However, if the main network device fails, the main network device cannot normally receive and transmit the message, but if the network interface state of the main network device is normal, the priority information in the heartbeat message cannot indicate that the main network device fails, and the main-standby switching cannot be realized in time, which affects the network connectivity.

In order to solve the above problem, embodiments of the present application provide a technical solution for network device switching, which is described in detail below.

Exemplary method

Fig. 1 is a schematic structural diagram of a silent dual-machine system according to an embodiment of the present application, where the silent dual-machine system includes a first network device 101 and a second network device 102, and the first network device 101 and the second network device 102 are connected through a heartbeat interface to interact heartbeat messages.

At least the first network device 101 is configured with a function of monitoring an IP Address (Internet Protocol Address). When the first network device 101 performs monitoring the IP address, it periodically establishes a communication connection with an external network device in the network except the silent dual-computer system, so as to record information of establishing the communication connection, including a result of establishing the communication connection and a response time required for establishing the communication connection.

The communication connection may be established in an ICMP (internet Control Message protocol) manner, that is, an ICMP request Message is sent to an external network device, and an ICMP response Message is received within a timeout period, so that the result of establishing the communication connection is a connection, and the response time required for successfully establishing the communication connection is recorded. If the ICMP response message is not received within the overtime time, the communication connection is established, and the communication is abnormal.

The communication connection may be established in a TCP (Transmission Control Protocol) manner, that is, a TCP request message is sent to an external network device, and a TCP response message and a TCP handshake message are received within a timeout period, so that the communication connection is established and response time required for successfully establishing the communication connection is recorded. If the TCP response message is not received within the timeout period, the communication connection is established, and the communication is abnormal.

Of course, it may also establish a communication connection with an external network device in another manner, and perform the function of monitoring the IP address to represent the quality of the communication connection of the first network device 101, which is not described herein.

Fig. 2 is a flowchart of a method for switching network devices according to an embodiment of the present application, where in the embodiment shown in fig. 2, both a first network device and a second network device are configured with a function of monitoring an IP address, and the method includes:

the first network device receives a heartbeat message sent by the second network device, wherein the heartbeat message includes second priority information and a second monitoring IP state of the second network device, and the second monitoring IP state is used for representing information of communication connection which can be provided by the second network device.

The first network device obtains first priority information and a first monitoring IP state of the first network device, wherein the first monitoring IP state is used for representing information of communication connection which can be provided by the first network device.

The first network device is configured with a function of monitoring an IP address, and tries to establish communication connection with the external network device at preset time intervals. A first listening IP state is maintained in the first network device, the first listening IP state being used to characterize information of the communication connections that the first network device is capable of providing.

The first monitoring IP state comprises a communication connection result, and when the first network equipment and the external network equipment establish communication connection successfully, the communication connection result is that the communication connection is normal; when the first network equipment fails to establish the communication connection with the external equipment, the communication connection result is abnormal communication connection.

The first listening IP state may further include a response time, which represents a time period required for the first network device to establish a communication connection with the external network device. It can be understood that the shorter the response time of the first network device to establish the communication connection with the external network device, the faster the communication connection speed that can be provided by the first network device, the better the quality of the communication connection; the longer the response time for the first network device to establish a communication connection with the external network device, the slower the speed of the communication connection that can be provided by the first network device, and the worse the quality of the communication connection.

The first network device also determines first priority information of the first network device according to a state of an interface interacting with the external network device.

The same principle is that: the second network device is configured with a function of monitoring the IP address, and tries to establish communication connection with the external network device at preset time intervals. A second listening IP state is maintained in the second network device, where the second listening IP state is used to represent information of communication connections that the second network device can provide.

The second monitoring IP state comprises a communication connection result, and when the second network equipment and the external network equipment establish communication connection successfully, the communication connection result is that the communication connection is normal; when the second network device fails to establish the communication connection with the external device, the communication connection result is that the communication connection is abnormal.

The second listening IP state may further include a response time, which represents a time period required for the second network device to establish a communication connection with the external network device. It can be understood that the shorter the response time of the second network device to establish the communication connection with the external network device, the faster the communication connection speed that can be provided by the second network device, the better the quality of the communication connection; the longer the response time for the second network device to establish a communication connection with the external network device, the slower the speed of the communication connection that can be provided by the second network device, and the worse the quality of the communication connection.

The second network device also determines second priority information of the second network device according to a state of an interface interacting with the external network device.

It should be noted that, when the first network device and the second network device are both configured with the function of monitoring the IP address, if the first network device is a standby network device, a network interface on the first network device interacting with an external network device is turned on, and a message related to the function of monitoring the IP address can be normally received and transmitted; similarly, if the second network device is a standby network device, the network interface on the second network device interacting with the external network device is opened, and the message related to the function of monitoring the IP address can be normally received and transmitted.

The first network equipment and the second network equipment in the same silent dual-computer system interact heartbeat messages through a heartbeat interface. The first network equipment sends a heartbeat message to the second network equipment, wherein the heartbeat message comprises first priority information and a first monitoring IP state. The first priority information represents the state of a network interface of the first network device interacting with the external network device, and the first monitoring IP state is used for representing the information of the communication connection which can be provided by the first network device. In a similar way, the second network device sends a heartbeat message to the first network device, where the heartbeat message includes the second priority information and the second monitored IP state. The second priority information represents a state of a network interface where the second network device interacts with the external network device, and the second monitoring IP state is used to represent information of communication connection that the second network device can provide.

And the first network equipment performs active-standby switching according to the first priority information and the first monitoring IP state of the first network equipment, and the second priority information and the second monitoring IP state in the received heartbeat message. In a similar way, the second network device performs active-standby switching according to the second priority information and the second monitored IP state of the second network device, and the first priority information and the first monitored IP state in the received heartbeat message.

Therefore, the first network device and the second network device interact through the heartbeat message, and the interaction includes not only priority information representing the interface state, but also a monitoring IP state representing the quality of the established communication connection.

And 203, when the first priority information and the second priority information are the same, the first network equipment is switched according to the first monitoring IP state and the second monitoring IP state.

In one example, if the first priority information and the second priority information are different, if the first priority information is high, the first network device is a master network device, and the second network device is a standby network device; if the second priority information is high, the first network device is a standby network device, and the second network device is a main network device. If the main/standby judgment result is consistent with the current actual main/standby condition, the main/standby switching is not executed; and if the main/standby judgment result is inconsistent with the current actual main/standby condition, executing main/standby switching.

In this embodiment, if the first priority information is the same as the second priority information, it indicates that the network interface states of the first network device and the second network device are the same. At this time, the master/slave switching is performed according to the monitored IP state representing the quality of the established communication connection, and specific implementation examples are described one by one below.

A first switching example: the first network device is a main network device, the first monitoring IP state represents that the communication connection of the first network device is abnormal, the second monitoring IP state represents that the communication connection of the second network device is normal, and the first network device is switched to a standby network device. At this time, the second network device is a standby network device, the first monitoring IP state represents that the communication connection of the first network device is abnormal, the second monitoring IP state represents that the communication connection of the second network device is normal, and the second network device is switched to the master network device.

A second handover example: the first network equipment is standby network equipment, the first monitoring IP state represents that the communication connection of the first network equipment is normal, the second monitoring IP state represents that the communication connection of the second network equipment is abnormal, and the first network equipment is switched into main network equipment. At this time, the second network device is the master network device, the first monitoring IP state represents that the communication connection of the first network device is normal, the second monitoring IP state represents that the communication connection of the second network device is abnormal, and the second network device is switched to the standby network device.

Then, it indicates that the first priority information and the second priority information are the same, and selects the network device with normal communication connection as the main network device and selects the network device with abnormal communication connection as the standby network device. If the main/standby judgment result is consistent with the current actual main/standby condition, the main/standby switching is not executed; and if the main/standby judgment result is inconsistent with the current actual main/standby condition, executing main/standby switching.

The third switching example: the first network device is a master network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection of the first network device and the second network device is normal, and when the first network device represents that the quality of the communication connection of the first network device is lower than that of the second network device, the first network device is switched to a standby network device. At this time, the second network device is a standby network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection between the first network device and the second network device is normal, and when the first network device represents that the quality of the communication connection between the first network device and the second network device is lower than that of the second network device, the second network device is switched to the main network device.

A fourth switching example: the first network device is a standby network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection of the first network device and the second network device is normal, and when the first network device is higher than the communication connection quality of the second network device, the first network device is switched to be a main network device. At this time, the second network device is the master network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection between the first network device and the second network device is normal, and when the representation that the quality of the communication connection between the first network device and the second network device is higher than that of the first network device, the second network device is switched to the standby network device.

The quality of the communication connection is measured by response time in the monitoring IP state, and the shorter the response time for establishing the communication connection by continuously presetting the number is, the higher the quality of the communication connection is; the longer the response time taken for establishing a communication connection with a preset number of consecutive numbers, the lower the quality of the communication connection.

When the first priority information and the second priority information are the same and the communication connection is normal, the network device with high communication connection quality is selected as the main network device, and the network device with low communication connection quality is selected as the standby network device. If the main/standby judgment result is consistent with the current actual main/standby condition, the main/standby switching is not executed; and if the main/standby judgment result is inconsistent with the current actual main/standby condition, executing main/standby switching.

The heartbeat messages interacted between the first network device and the second network device through the heartbeat interface may further include a Media Access Control (MAC) Address.

A fifth switching example: the first network device is a master network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection of the first network device and the second network device is normal, and represent that the quality of the communication connection of the first network device is the same as that of the second network device, the MAC address of the first network device is smaller than that of the second network device, and the first network device is switched to a standby network device. At this time, the second network device is a standby network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection between the first network device and the second network device is normal, and represent that the quality of the communication connection between the first network device and the second network device is the same as that of the communication connection between the first network device and the second network device, the MAC address of the first network device is smaller than that of the second network device, and the second network device is switched to be the main network device.

A sixth switching example: the first network device is a standby network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection of the first network device and the second network device is normal, and represent that the quality of the communication connection of the first network device is the same as that of the second network device, the MAC address of the first network device is larger than that of the second network device, and the first network device is switched to be a main network device. At this time, the second network device is the master network device, the first monitoring IP state and the second monitoring IP state represent that the communication connection between the first network device and the second network device is normal, and represent that the quality of the communication connection between the first network device and the second network device is the same, the MAC address of the first network device is larger than that of the second network device, and the second network device is switched to the standby network device.

When the first priority information and the second priority information are the same and the communication connection is normal, and the communication connection quality is the same, the network device with the small MAC address is selected as the master network device, and the network device with the large MAC address is selected as the standby network device. If the main/standby judgment result is consistent with the current actual main/standby condition, the main/standby switching is not executed; and if the main/standby judgment result is inconsistent with the current actual main/standby condition, executing main/standby switching.

In each of the above examples shown in fig. 2, when the main network device is switched to the standby network device, the network interface of the main network device only interacts with the external network device to monitor the message related to the IP address function; when the standby Network device is switched to the main Network device, the Network interface of the standby Network device and the external device normally interact with a Network message, an IP Address of the Network interface of the standby Network device and an ARP (Address Protocol) of a public Network Address of NAT (Network Address Translation) are notified to the Network interface of the interconnected external Network device, the interconnected external Network device is notified to update a forwarding table item, and therefore the interconnected external Network device can send the Network message to a new main Network device, and the main-standby switching is achieved.

As can be seen from the above, in the embodiment of the present application, the network device with the function of monitoring the IP is configured, when the priority information of the main network device and the standby network device is the same, the switching is performed according to the obtained monitored IP state, and in the muting system, a technical scheme for implementing the switching between the main network device and the standby network device by using the method of monitoring the IP state is provided, so that communication interruption caused by a normal interface state and a network device failure is avoided.

301, the first network device receives a heartbeat message sent by the second network device, wherein the heartbeat message includes second priority information of the second network device.

The first network device obtains first priority information of the first network device and a monitoring IP state, wherein the monitoring IP state is used for representing information of communication connection which can be provided by the first network device.

And 303, when the first priority information is the same as the second priority information and the monitoring IP state represents that the communication connection of the first network equipment is abnormal, switching the first network equipment into standby network equipment.

The first network equipment is main network equipment, is configured with a function of monitoring an IP address, and can acquire a monitoring IP state so as to represent information of establishing communication connection between the first network equipment and external network equipment. The second network device is a standby network device, a network interface interacting with the external network device is closed, and the function of monitoring the IP address is not configured. And the second network equipment sends a heartbeat message to the first network equipment, wherein the heartbeat message only comprises second priority information of the second network equipment.

The first network device compares the local first priority information with the second priority information, and if the first priority information is higher than the second priority information, the primary/standby switching is not performed. If the first priority information is the same as the second priority information and the monitoring IP state indicates that the communication connection established between the first network device and the external device is normal, the master-slave switching is not performed.

And if the first priority information is the same as the second priority information and the monitoring IP state represents that the communication connection established between the first network equipment and the external equipment is abnormal, switching the first network equipment into standby network equipment. At this point, the second network device is switched to the master network device.

It should be noted that, when the main network device is switched to the standby network device, the network interface for the communication between the main network device and the external network device is closed; the standby network equipment starts a network interface communicated with the external network equipment, informs the IP address of the network interface of the standby network equipment and the ARP of the public network address of the NAT to the network interfaces of the interconnected external network equipment, and informs the interconnected external network equipment to update a forwarding table entry, so that the interconnected external network equipment can send a network message to the new main network equipment, and the main-standby switching is realized.

Therefore, although the first priority information and the second priority information are the same and indicate that the external interface states of the first network device and the second network device are the same, when the monitored IP state indicates that the communication connection established between the first network device and the external network device is abnormal, the first network device fails, at this time, the first network device is switched from the main network device to the standby network device, and the second network device is switched from the standby network device to the main network device. In the silent dual-computer system, the main-standby switching realized by adopting the function of monitoring the IP address is provided. And communication interruption caused by normal interface state and network equipment failure is avoided.
