[0002] High-availability solutions for distributed databases ensure continuous service delivery even in the event of network node failures or network anomalies, guaranteeing data consistency and integrity. In high-availability solutions, monitoring the communication status of network nodes and automatic failover in case of failure are key to ensuring continuous database service.

[0003] However, in existing distributed database high availability solutions, network nodes are usually configured with only one IP (Internet Protocol) address. When network congestion occurs, database services will be interrupted. During network fluctuations, frequent switching of network nodes will occur, affecting the consistency of database services. Summary of the Invention

[0006] By using the mapping relationship between at least two Internet Protocol addresses and network interface cards (NICs) of each network node, at least two network connection channels between network nodes are determined.

[0007] The communication status between network nodes is detected through at least two network connection channels between network nodes;

[0008] Specifically, when performing communication status detection between network nodes, the communication status detection message is converted into a communication status detection message of at least two Internet protocol types.

[0009] Based on the communication status detection results of each network connection channel between network nodes, determine whether the communication status of the network nodes is normal.

[0017] The technical solution of this invention determines at least two network connection channels between each pair of network nodes by mapping at least two Internet Protocol (IP) addresses to network interface cards (NICs) of each network node. Communication status detection is performed on each of these channels, with the detection messages transmitted in at least two different IIP types. Finally, based on the communication status detection results of each network connection channel, the communication status of the network nodes is determined to be normal.

[0028] Example 1

[0029] Figure 1 The flowchart of a communication status detection method provided in Embodiment 1 of the present invention is applicable to the situation of communication status detection of network nodes in a distributed database. The method can be executed by a communication status detection device, which can be implemented in hardware and / or software and can be configured in the distributed database.

[0030] like Figure 1 As shown, the method includes:

[0031] S110. Determine at least two network connection channels between network nodes by using the mapping relationship between at least two Internet Protocol addresses and network interface cards (NICs) of each network node.

[0032] In this context, a network node refers to a node in the distributed database, and an Internet Protocol address refers to an IP (Internet Protocol) address. In this embodiment, each network node is assigned at least two IP addresses, but there is no limit to the number of IP addresses assigned to each network node. A network interface card (NIC), also known as a network adapter, is a hardware device that connects a network node to the network, used for data encapsulation and decapsulation, link management, etc. A NIC can be bound to multiple IP addresses, but an IP address can only be bound to one NIC. Furthermore, for multiple IP addresses of a network node, the NICs bound to them can be the same or different.

[0033] In this embodiment, a mapping relationship between at least two Internet Protocol (IP) addresses and network interface cards (NICs) of each network node is pre-configured. Specifically, the mapping relationship can be represented in the form of key-value pairs. For example, the mapping relationship between the IP address and NIC of network node 1 can be configured as: {node1_ip1:eth1, node1_ip2:eth2}, and the mapping relationship between the IP address and NIC of network node 2 can be configured as: {node2_ip3:eth1, node2_ip4:eth2}.

[0034] Furthermore, the sources of the mapping relationship between Internet Protocol addresses and network interface cards (NICs) include: pre-storing the mapping relationship between at least two Internet Protocol addresses of a network node and a NIC; and / or, determining the NIC that matches the Internet Protocol address based on the Internet Protocol address of the network node through operating system network commands, and storing the mapping relationship between the Internet Protocol address and the NIC.

[0035] Specifically, when deploying a distributed database, the mapping relationship between network node IP addresses and network interface cards (NICs) is pre-stored. This mapping relationship can be represented as key-value pairs of IP addresses and NIC names.

[0036] If, during the deployment of a distributed database, only at least two IP addresses of the network nodes are determined, the network interface card information corresponding to each IP address can be obtained through operating system network commands such as ipconfig or ifconfig, and the mapping relationship between IP addresses and network interfaces can be stored in the form of key-value pairs.

[0037] Furthermore, S110 may include: establishing a network connection channel between the Internet Protocol address of the first network node and the Internet Protocol address of the second network node corresponding to the same Internet Protocol address, based on the mapping relationship between at least two Internet Protocol addresses of the first network node and the second network node and the network interface card.

[0038] At least two network connection channels between network nodes are established based on the same network interface card (NIC) between each pair of network nodes. By resolving the mapping relationship between the Internet Protocol (IP) address of each network node and the NIC, a network connection channel with the same NIC is established between each pair of network nodes.

[0039] Taking network node 1 and network node 2 as examples, the network connection channels between network node 1 and network node 2 are node1_ip1—node2_ip3 corresponding to network card eth1, and node1_ip2—node2_ip4 corresponding to network card eth2.

[0040] In this embodiment, by setting multiple mapping relationships between IP addresses and network cards for each network node, multi-NIC communication can be achieved between the network nodes. The advantage of multi-NIC communication is that after the communication of the network connection channel corresponding to one NIC fails, the communication connection can be switched to the network connection channel corresponding to another NIC, thereby improving the high availability function of the distributed database.

[0041] S120. Detect the communication status between network nodes through at least two network connection channels between network nodes.

[0042] The communication status detection is used to check whether network nodes can communicate normally. For example, this can be achieved through network packet sending tests, ping tests, etc. Specifically, communication status detection can be performed after the distributed database is deployed, establishing communication connections between network nodes, such as TCP (Transmission Control Protocol) connections; alternatively, it can be performed during the operation of the distributed database according to communication status detection instructions, or periodically according to a pre-set time period. This embodiment does not impose any limitations on this. Furthermore, communication status detection between network nodes can be performed through network interface cards pre-configured in the distributed database.

[0043] Furthermore, S120 may include:

[0044] Perform communication status detection on the network connection channel corresponding to the current network card between the first network node and the second network node;

[0045] If the communication status detection result of the network connection channel corresponding to the current network card is determined to be communication failure, then the communication status detection is performed on the network connection channel corresponding to the next network card until the communication status detection result is determined to be communication success, or the communication status detection of the network connection channels corresponding to all network cards is completed.

[0046] The first network node and the second network node refer to the two network nodes currently conducting the communication status test. The terms "first" and "second" are only used to distinguish different network nodes and are not used to indicate order, etc.

[0047] In this embodiment, communication status tests are performed on each pair of network nodes that have established communication connections in the distributed database. For the first and second network nodes currently undergoing communication status testing, since each network card has multiple network connection channels, the communication status of each network connection channel can be checked sequentially. If at least one network connection channel is found to be successfully communicating, then communication between the first and second network nodes is considered normal. If communication status checks are performed on all network connection channels corresponding to all network cards and all communication fails, then communication between the first and second network nodes is considered to have failed.

[0048] In this embodiment, a multi-NIC communication mechanism is set up, allowing network nodes to communicate through multiple network connection channels. If communication fails in one NIC's network connection channel, communication can be directly switched to another NIC's network connection channel. Communication failure between network nodes is only confirmed when all NICs' corresponding network connection channels have failed. This multi-NIC communication mechanism improves the availability of network nodes and the fault tolerance of inter-node communication, reducing frequent switching of network nodes due to network failures or other reasons.

[0049] Furthermore, when performing communication status detection between network nodes, the communication status detection message is converted into a communication status detection message of at least two Internet protocol types.

[0050] The Internet protocol type refers to the IP type, which can include IPv4 or IPv6, etc. A message forwarder can be set up locally in the distributed database. Network nodes send communication status detection messages or messages during normal communication to the message forwarder, which then performs the Internet protocol type conversion. For example, using IPv4 or IPv6 as the IP type, the message forwarder converts IPv4 communication status detection messages to IPv6, or vice versa. In other words, regardless of whether it's a communication status detection message or a message during normal communication, after passing through the message forwarder, it becomes a communication status detection message of various Internet protocol types, but the message content is the same regardless of the Internet protocol type.

[0051] In this embodiment, to further improve the high availability of the distributed database, a dual-stack communication mode can be constructed by converting communication status detection messages into at least two different Internet protocol types. The advantage of this setup is that regardless of the Internet protocol type supported by the message receiver, message parsing of the communication status detection messages can be achieved. Therefore, by combining multi-NIC communication with the dual-stack communication mode, the high availability of the database is further improved.

[0052] S130. Based on the communication status detection results of each network connection channel between network nodes, determine whether the communication status of the network nodes is normal.

[0053] In this embodiment, based on the detection results of the communication status of each pair of network nodes, it is determined whether the communication status of the network node is normal, that is, whether the network node is a faulty node.

[0054] Understandably, in the multi-NIC communication mechanism of this embodiment, as long as at least one network connection channel is functioning normally, the communication status between any two network nodes is considered normal. Communication between network nodes is only considered to have failed when all network connection channels fail. However, when communication between network nodes fails, the cause may be a failure of one or both network nodes. Therefore, it is necessary to screen for faulty network nodes based on the communication status detection results between network nodes.

[0055] Furthermore, S130 may include: if it is determined that the communication status detection results of each network connection channel between the target network node and at least two other network nodes are all communication failures, then the communication status of the target network node is determined to be abnormal, and the target network node is a faulty node.

[0056] For example, if all network connection channels between network node 1 and network node 2 fail to communicate, and if all network connection channels between network node 1 and network node 3 fail to communicate, then network node 1 is identified as a faulty node.

[0057] In this embodiment, the higher the probability that all network connection channels with other network nodes fail to communicate, the higher the frequency of the network node being a faulty node. Therefore, a network node that fails to communicate with multiple other network nodes can be identified as a faulty node.

[0058] Furthermore, this embodiment can also flexibly set the number threshold of other network nodes according to the actual application of the distributed database. When the number of other network nodes whose communication status detection results of each network connection channel with the target network node are all communication failures is greater than or equal to the preset number threshold, the target network node is identified as a faulty node.

[0059] In this embodiment, a multi-NIC communication mechanism is combined with a dual-stack communication mode. As long as the network connection channels corresponding to all NICs of the network nodes in the database are not completely faulty, service can be continuously provided without network node switching. Network node switching only occurs when all network connection channels corresponding to all NICs fail. This fully utilizes server network resources, achieving highly available communication and fault detection capabilities. Furthermore, it avoids frequent network node switching caused by network fluctuations and failures, ensuring the consistency and stability of the database's data processing services.

[0060] The technical solution of this invention determines at least two network connection channels between each pair of network nodes by mapping at least two Internet Protocol (IP) addresses to network interface cards (NICs) of each network node. Communication status detection is performed on each of these channels, with the detection messages transmitted in at least two different IIP types. Finally, based on the communication status detection results of each network connection channel, the communication status of the network nodes is determined to be normal. This technical solution reduces frequent database switching caused by network fluctuations, enabling continuous service provision without database switching even when the NICs of each network node are not completely faulty. It fully utilizes the network resources of the distributed database for high-availability communication status detection, enhancing high-availability communication capabilities.

[0061] Example 2

[0062] Figure 2 This is a flowchart of a communication status detection method provided in Embodiment 2 of the present invention. Based on the above embodiments, the present invention further specifies the communication status detection process, the process of dual-stack communication based on at least two Internet protocol types, and the process of judging the communication status of network nodes.

[0063] like Figure 2 As shown, the method includes:

[0064] S210. Based on the mapping relationship between at least two Internet Protocol addresses of the first network node and the second network node and the network interface card, establish a network connection channel between the Internet Protocol address of the first network node and the Internet Protocol address of the second network node corresponding to the same network interface card.

[0065] The process of establishing network connection channels between network nodes and their corresponding network cards based on the mapping relationship between network node IP addresses and network cards, thereby enabling multi-NIC communication, has been described in the above embodiments, and this embodiment does not impose any limitations on this.

[0066] Furthermore, Internet Protocol addresses include Internet Protocol addresses of at least two Internet Protocol types.

[0067] This embodiment, based on the above embodiments, allows the same network interface card (NIC) to be configured with both IPv4 and IPv6 addresses simultaneously. This further constructs a mesh communication structure on top of multi-NIC communication. Figure 3 This is a schematic diagram of a multi-NIC mesh communication structure provided in this embodiment, as shown below. Figure 3 As shown, in the above embodiment, the mapping relationship between the IP address and network card of network node 1 is {node1_ip1: eth1, node1_ip2: eth2}, and the mapping relationship between the IP address and network card of network node 2 is {node2_ip3: eth1, node2_ip4: eth2}. Furthermore, eth1 and eth2 of network node 1 correspond to IPv4 and IPv6 addresses respectively, and similarly, eth1 and eth2 of network node 2 also correspond to IPv4 and IPv6 addresses respectively. This configuration expands the network connection channels between network node 1 and network node 2 from the original node1_ip1—node2_ip3 and node1_ip2—node2_ip4 to four network connection channels: node1_ipv4 1—node2_ipv4 3, node1_ipv6 1—node2_ipv6 3, node1_ipv4 2—node2_ipv4 4, and node1_ipv6 2—node2_ipv6 4.

[0068] In this embodiment, by configuring Internet Protocol addresses of different Internet Protocol types on the same network card, the number of network connection channels between network nodes is further expanded, and the high availability of the distributed database is further improved.

[0069] S220. Detect the communication status of the network connection channel corresponding to the current network card between the first network node and the second network node.

[0070] S230. If the communication status detection result of the network connection channel corresponding to the current network card is determined to be communication failure, then the communication status detection is performed on the network connection channel corresponding to the next network card until the communication status detection result is determined to be communication success, or the communication status detection of the network connection channels corresponding to all network cards is completed.

[0071] If the communication status detection result of the network connection channel corresponding to the current network card is successful, it indicates that the communication status between the first network node and the second network node is normal. If the communication status detection result of the network connection channel corresponding to the current network card is unsuccessful, the communication status detection continues for the next network connection channel corresponding to the next network card. As long as the communication status detection result of at least one network connection channel corresponding to the network card is successful, the communication status between the first network node and the second network node can be considered normal. If the communication status detection result of all network connection channels is unsuccessful, then the communication between the first network node and the second network node has failed, and the first network node and / or the second network node is a faulty node.

[0072] Furthermore, when performing communication status detection between network nodes, the communication status detection message is converted into a communication status detection message of at least two Internet Protocol types, including: converting a communication status detection message of a first Internet Protocol type sent by a network node into a communication status detection message of a second Internet Protocol type through a message forwarder.

[0073] In this embodiment, a dual-stack communication mode is implemented based on a message forwarder. The specific details of the dual-stack communication mode have been described in the above embodiments, and this embodiment does not impose any limitations on it.

[0074] Furthermore, a network node that receives communication status detection messages of at least two Internet Protocol types sent by a message forwarder processes the communication status detection message of the Internet Protocol type that matches it.

[0075] In dual-stack communication mode, regardless of the Internet protocol type, communication status detection messages are forwarded to the message receiver's network node in at least two Internet protocol types after being sent to the message forwarder by the sending network node. Upon receiving at least two different types of communication status detection messages, the receiving network node can parse and process only those messages corresponding to its supported Internet protocol types. If the receiving network node supports multiple Internet protocol types, it can choose to process only one type of communication status detection message, avoiding redundant processing of other messages to prevent resource waste and maintain communication status detection efficiency.

[0076] Similarly, under normal communication conditions, network nodes can also communicate based on a dual-stack communication mode. The network node sending the message sends the communication message to the message forwarder, which performs format conversion and forwards the communication messages of various Internet protocol types to the network node receiving the message. The network node receiving the message then selects the communication message of the Internet protocol type it supports for processing from the communication messages of various Internet protocol types.

[0077] S240. If it is determined that the communication status detection results of each network connection channel between the target network node and at least two other network nodes are all communication failures, then the communication status of the target network node is determined to be abnormal, and the target network node is a faulty node.

[0078] In this embodiment, a network node that fails to communicate with multiple other network nodes through the network connection channels corresponding to each network card is identified as a faulty node.

[0079] After identifying the target network node as a faulty node, a network node switch can be performed, selecting another network node with normal communication status in the distributed database system to continue providing data services.

[0080] The technical solution of this embodiment, based on the mapping relationship between IP addresses and network interface cards (NICs) in network nodes, constructs NIC-based network connection channels between network nodes. Simultaneously, different Internet Protocol (IP) types of IP addresses can be configured for the same NIC, forming a mesh structure of network connection channels. When communicating based on the same network connection channel, a message forwarder is configured to convert Internet Protocol types and forward messages of multiple Internet Protocol types, realizing a multi-NIC mesh communication mechanism and dual-stack communication mode between network nodes, improving the fault tolerance and availability of communication between network nodes. For each pair of network nodes, the communication status of each network connection channel is detected. If at least one network connection channel is communicating normally, the communication between network nodes is considered normal. If all network connection channels fail to communicate, the communication between network nodes is considered to have failed, and the node that has failed to communicate with multiple other network nodes is identified as a faulty node, and network node switching is performed. While ensuring the continuity of distributed database data service provision, it reduces network node switching caused by network fluctuations and network failures, improving the high availability and system stability of the distributed database.

[0086] The network node communication status judgment module 330 is used to determine whether the communication status of the network node is normal based on the communication status detection results of each network connection channel between network nodes.

[0087] The technical solution of this invention determines at least two network connection channels between each pair of network nodes by mapping at least two Internet Protocol (IP) addresses to network interface cards (NICs) of each network node. Communication status detection is performed on each of these channels, with the detection messages transmitted in at least two different IIP types.
