Description

Technical Field

[0001] The present invention relates to the field of computer and Internet technologies, and in particular to a data processing method, device and storage medium. Background Art

[0002] In the related art, multiple servers communicate data through switches. When any server takes a faulty / sub-healthy network port offline, the server can no longer sense whether the status of the offline network port has been restored, and can no longer take recovery measures, resulting in a reduction in the number of network ports and low data communication efficiency. In addition, when the server detects a physical link failure / sub-health of the aggregation port, but does not detect a specific destination port link failure, even if the service is switched to a normal network port at the sending end, due to the load algorithm of the switch chip, the data will still pass through the faulty link at the destination end, resulting in low security and efficiency of data communication.

[0076] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention are further elaborated in detail below in conjunction with the drawings and embodiments. The described embodiments should not be regarded as limiting the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0077] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0078] If similar descriptions of "first / second" appear in the invention document, the following description is added. In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the invention described herein can be implemented in an order other than that illustrated or described herein.

[0079] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0080] Exemplary, combined Figure 1 In the related art, server A and server B communicate data through a switch. Server A includes: network port A1 and network port A2. Server B includes: network port B1 and network port B2. Among them, link 1 is formed between server A and server B through network port A1 and network port B1. After the link between the switch and network port B1 fails, when server A sends a service message to server B, server A switches the link to link 2 corresponding to network port A2. Due to the switch algorithm, the switch will still send the service message to server B through network port B1, which will cause the service message to be unable to be sent to server B, resulting in low data communication efficiency and security.

[0081] The present invention provides a data processing method. Figure 2 , is an optional flow chart of a data processing method provided by an embodiment of the present invention, which is combined with Figure 2 The steps shown are explained.

[0082] S101. In a current detection cycle, a certain number of current detection messages are sent to each node to be tested based on the constructed virtual address information; the certain number represents a number greater than the number of network ports of the corresponding node to be tested.

[0083] In the embodiment of the present invention, the detection node sends a certain number of current detection messages to each node to be detected based on the constructed virtual address information during the current detection cycle. The certain number represents a number greater than the number of network ports of the corresponding node to be detected.

[0084] In an embodiment of the present invention, a network system includes multiple servers, devices to be accessed, etc. Among them, multiple servers communicate data through switches. The detection node can be each server, device to be accessed, etc. The node to be tested can be other servers except the server corresponding to the detection node. In other words, each server in the network system sends a certain number of current detection messages to each other server in each detection cycle. Multiple network ports of each server form an aggregate network port.

[0085] In an embodiment of the present invention, the detection node determines the number of network ports of each node to be tested in a local information table. The server forms a current detection message for each node to be tested based on the constructed virtual address information. The number of detection messages for each node to be tested is greater than the corresponding number of network ports so that the detection message can fully cover the network ports of the node to be tested.

[0086] In an embodiment of the present invention, the detection node may send a corresponding current detection message to each node to be detected every 10 seconds. In other embodiments, the detection node may also send a current detection message to each node to be detected every 1 minute. In an embodiment of the present invention, there is no limit on the duration of the detection cycle.

[0087] In the embodiment of the present invention, when there are 10 servers in the network system, each server sends a certain number of detection messages to the other 9 servers in each detection cycle.

[0088] S102: Receive a current response message fed back by each node to be tested in response to the current detection message.

[0089] In the embodiment of the present invention, the detection node receives the current response message fed back by each node to be detected in response to the current detection message.

[0090] In the embodiment of the present invention, after the node under test receives the corresponding current detection message, the node under test forms the same number of current response messages and feeds them back to the detection node. Since there is a link failure between the node under test and the detection node, the number of current detection messages received by the node under test and the number of current detection messages sent by the detection node may be inconsistent.

[0091] S103: Determine a communication link detection result between each node to be tested based on the current response message and the current detection message.

[0092] In the embodiment of the present invention, the detection node determines the communication link detection result between the detection node and each node to be detected based on the current response message and the current detection message.

[0093] In the embodiment of the present invention, the detection node can calculate the packet loss rate through the current response message and the current detection message. If the packet loss rate is greater than the packet loss rate threshold, the communication link detection result that the link between the corresponding node to be tested and the detection node is abnormal is determined. If the packet loss rate is not greater than the packet loss rate threshold, the communication link detection result that the link between the corresponding node to be tested and the detection node is normal is determined.

[0094] In the embodiment of the present invention, the detection node can also obtain the delay information corresponding to the current response message, and if the delay information is greater than the delay threshold, the communication link detection result that the link between the corresponding node to be tested and the detection node is abnormal is determined. If the delay information is not greater than the delay threshold, the communication link detection result that the link between the corresponding node to be tested and the detection node is normal is determined.

[0095] Among them, the communication link includes physical link and data link. The physical link refers to a physical line from one node to an adjacent node without any other switching nodes in between. When performing data communication, the path between two servers is often composed of many links in series. The data link means that in addition to the physical line, there must also be a communication protocol to control the transmission of this data. The hardware and software that implement these protocols are added to the link, which is a data link. The data link is also called a logical link.

[0096] S104. When the communication link detection result indicates that the target node link is abnormal, the service message is modified based on the preset address resolution protocol table by loading a preset program to obtain a target message to be sent to the target node; wherein the address resolution protocol table contains the sending rule information between each node to be tested, and the address resolution protocol table is determined by the detection message in the detection cycle before the current detection cycle.

[0097] In the embodiment of the present invention, when the communication link detection result indicates that the target node link is abnormal, the detection node modifies the service message based on the preset address resolution protocol table by loading a preset program to obtain the target message to send to the target node. The address resolution protocol table contains the sending rule information between each node to be detected, and the address resolution protocol table is determined by the detection message in the detection cycle before the current detection cycle.

[0098] In an embodiment of the present invention, when the communication link detection result indicates that the target node link is abnormal, the detection node loads a preset program. The detection node determines the switch forwarding rule based on the address resolution protocol table, and determines the replacement address information corresponding to the target node in the address resolution protocol table. The detection node responds to the preset program and modifies the address information in the service message sent to the target node to the replacement address information according to the switch forwarding rule to obtain the target message.

[0099]

[0100] Table 1: Address resolution protocol table

[0101] Exemplarily, in combination with Table 1, since the second source physical address information corresponding to host-B is inconsistent, and the source physical address information of host-C is inconsistent, the detection node can determine that the switch forwarding rule is the source destination address forwarding algorithm. At this time, when the target node is host-B, the detection node can determine a replacement address information in its corresponding source physical address information or second source physical address information. The detection node uses the replacement address information to replace the source address information or the destination address information in the service message, and forms a target message to send to host-B.

[0102] In an embodiment of the present invention, the detection node sends a certain number of first detection messages to each node to be detected based on the constructed first virtual address information within the first detection cycle. The first detection cycle is located before the current detection cycle. The detection node receives the first response message fed back by each node to be detected in response to the first detection message. The detection node constructs an address resolution protocol table based on the first detection message and the first response message.

[0103] In the embodiment of the present invention, the first detection cycle is located before the current detection cycle, and the communication link of each node to be tested is normal. The detection node sends a first detection message to each node to be tested in the first detection cycle. Since the communication link is normal, each node to be tested will also feedback the same number of first response messages to the detection node. And the first detection message and the first response message are one-to-one corresponding.

[0104] In an embodiment of the present invention, the detection node constructs each row of the address resolution protocol table based on the source physical address information and the local aggregate network port identifier contained in each first detection message of each node to be tested, the second source physical address information contained in the corresponding first response message, the corresponding node to be tested identifier, the corresponding node to be tested network port identifier, and the aggregate network port information of the corresponding node to be tested, thereby obtaining the address resolution protocol table.

[0105] Exemplary, combined Figure 3 , HOST A includes network ports NIC0 and NIC1. NIC0 and NIC1 form aggregate network port band0. HOST B includes network ports NIC2 and NIC3. NIC2 and NIC3 form aggregate network port band1. The construction process of the address resolution protocol table may include:

[0106] HOST A host agent randomly selects a mac address, starting from the last byte + 1, and takes 8 consecutive media access control addresses (media access control address, mac), which may include: address (macA0 ~ macA7). HOSTA host obtains the mac of HOST B host aggregation network port bond1 through the information table, and constructs 8 current detection messages in the form of macA0 ~ macA7 → HOST B host bond1 mac, and sends them to HOST B host bond1. Among them, the current detection message includes: HOST A host identifier and aggregation network port band0 identifier and mac.

[0107] The HOST B agent will also obtain 8 consecutive mac addresses (macB0~macB7) through the same random algorithm. When HOST B receives the current detection message from HOST A, it will send a reply to A in the format of macB0~macB7→HOSTA host's aggregated network port bond0 mac. Among them, any network port of HOSTB receives the current detection message and forms a corresponding current response message to send a reply. Among them, the current response message includes: HOST B host identifier and corresponding network port identifier. The 8 current detection messages of HOST A cover all member ports of bond1 of HOST B. HOST A analyzes the 8 packets covering all member ports of bond1 of HOST B, and can obtain the source mac and destination mac of the message sent to NIC2 and NIC3 of HOST B. Then the sending link detection of HOSTA host→HOSTB host is completed, and the address resolution protocol table is obtained. Otherwise, continue to the next step and perform detection by modifying the destination mac.

[0108] HOST A reconstructs the current detection message, and uses the mac of bond0 of host A as the source mac, and macA0~macA7 as the destination mac to construct 8 current detection messages and send them to bond1 of host HOST B. When host HOST B receives the current detection message from host HOST A, it sends back packets to host HOSTA in the format of macB0~macB7→bond0mac of host HOSTA. Host HOSTA analyzes the 8 packets covering all member ports of bond1 of host HOSTB, and can obtain which two source mac and destination mac should be used for the message sent to NIC2 and NIC3 of host HOSTB. Then the sending link detection of host HOSTA→host HOSTB is completed, and the address resolution protocol table is obtained.

[0109] In the embodiment of the present invention, when the communication link detection result indicates that the link is normal, the detection node uninstalls the preset program and sends the service message as the target message to the target node.

[0110] In an embodiment of the present invention, when the communication link detection result indicates that the target node link is abnormal, the detection node sends a loading notification message to the target node, so that the target node can load a second preset program based on the loading notification message; wherein the target node constructs a target response message based on the second preset program for feedback.

[0111] In the embodiment of the present invention, after sending the target message to the target node, the detection node receives a target response message fed back by the target node in response to the target message.

[0112] In the embodiment of the present invention, the detection node sends a certain number of current detection messages to each node to be tested based on the constructed virtual address information within the current detection cycle; receives the current response message fed back by each node to be tested in response to the current detection message; determines the communication link detection result between each node to be tested based on the current response message and the current detection message; when the communication link detection result indicates that the target node link is abnormal, the service message is modified based on the preset address resolution protocol table by loading a preset program to obtain the target message to be sent to the target node; wherein the address resolution protocol table contains the sending rule information between each node to be tested, and the address resolution protocol table is determined by the detection message within the detection cycle before the current detection cycle. Since the present scheme can detect the communication link detection result between each node to be tested in real time within each detection cycle, when the communication link of a node to be tested is abnormal, the preset program can be loaded to modify the service message of the node to be tested based on the address resolution protocol table, so that the service message can be sent to the corresponding node, and the efficiency and security of data communication can be improved when the link fails.

[0113] In some embodiments, Figure 2 The illustrated S101 to S102 may also be implemented through S105 to S108, which will be described in conjunction with each step.

[0114] S105: Determine the number N of network ports of each node to be tested in the local information table.

[0115] In the embodiment of the present invention, the detection node determines the number N of network ports of each node to be tested in the local information table. The information table stores the network port information and aggregated network port information of each node to be tested. N is an integer greater than or equal to 1.

[0116] S106. Construct N to the power of M virtual address information according to predetermined program instructions; M is an integer greater than 1.

[0117] In the embodiment of the present invention, the detection node constructs N to the Mth power virtual address information according to a predetermined program instruction. M is an integer greater than 1.

[0118] In the embodiment of the present invention, the detection node randomly constructs a plurality of virtual address information according to a predetermined program instruction.

[0119] For example, if the number of network ports of a node to be tested is 2, the detection node can construct 2×2×2=8 virtual address information corresponding to the node to be tested. In other embodiments, the detection node can also construct 10 virtual address information. The number of multiple virtual address information is greater than the number of network ports of the corresponding node to be tested.

[0120] S107 . Based on the N to the Mth power virtual address information, N to the Mth power current detection messages corresponding to each node to be tested are formed, and sent to each node to be tested.

[0121] In the embodiment of the present invention, the detection node forms N to the power of M current detection messages corresponding to each node to be detected based on N to the power of M virtual address information, and sends the messages to each node to be detected.

[0122] In an embodiment of the present invention, the detection node uses N to the power of M virtual address information as source physical address information, and uses the address information of the aggregated network port of each node to be tested as destination physical address information, and combines the local identifier, the local aggregated network port identifier, and the local aggregated network port physical address information to form N to the power of M current detection messages.

[0123] In an embodiment of the present invention, the detection node uses N to the power of M virtual address information as the destination physical address information, and the local aggregate network port physical address information as the source physical address information, and combines the local identifier and the local aggregate network port identifier to form N to the power of M current detection messages.

[0124] S108 : Receive K current response messages fed back by each node to be tested in response to N to the power of M current detection messages.

[0125] In the embodiment of the present invention, the detection node receives each detected node responding to N to the power of M current detection messages, and feeds back K current response messages, where K is an integer.

[0126] In the embodiment of the present invention, since the communication conditions between each node to be tested and the detection node are different, when the communication link between a node to be tested and the detection node is abnormal, the number of current detection messages received by the node to be tested is not equal to N to the power of M. The number of K current response messages is determined by the number of normal network ports of the node to be tested.

[0127] In an embodiment of the present invention, the detection node sends a current detection message sufficient to cover all network ports to each node to be tested. When there is any network port failure, the detection node can detect the link failure of the node to be tested, and then modify the business message, thereby realizing the sending of business messages when the link fails and improving data communication efficiency.

[0128] In some embodiments, Figure 2 The illustrated S103 to S104 may also be implemented through S109 to S112, which will be described in conjunction with each step.

[0129] S109, calculating the packet loss rate through the K current response messages fed back by the target node and N to the Mth power current detection messages, comparing the packet loss rate with the packet loss rate threshold, and determining the communication link detection result of each node to be tested.

[0130] In the embodiment of the present invention, the detection node calculates the packet loss rate through K current response messages fed back by the target node and N to the power of M current detection messages, compares the packet loss rate with the packet loss rate threshold, and determines the communication link detection result of each node to be tested.

[0131] In an embodiment of the present invention, the detection node calculates the ratio of K to the Mth power of N to obtain the packet loss rate. If the packet loss rate is greater than the first packet loss rate threshold, the communication link detection result corresponding to the sub-health of the node link to be tested is determined. If the packet loss rate is greater than the second packet loss rate threshold, the communication link detection result corresponding to the node link failure to be tested is determined. If the packet loss rate is less than the first packet loss rate threshold, the communication link detection result corresponding to the node link to be tested is determined to be normal. Among them, the first packet loss rate threshold is less than the second packet loss rate threshold.

[0132] In the embodiment of the present invention, the detection node obtains the delay information of the K response messages, compares the delay information with the delay threshold, and determines the communication link detection result of each node to be tested.

[0133] In an embodiment of the present invention, if the delay information is greater than the first delay threshold, the communication link detection result corresponding to the node to be tested is determined to be sub-healthy. If the delay information is greater than the second delay threshold, the communication link detection result corresponding to the node to be tested link failure is determined. If the delay information is less than the first delay threshold, the communication link detection result corresponding to the node to be tested link is determined to be normal. Wherein, the first delay threshold is less than the second delay threshold.

[0134] Among them, link sub-health (fail slow) refers to a state in which the hardware can operate normally but the performance is seriously degraded. Hardware components such as hard disk modules, network cards, central processing units (CPUs), and memory may enter a sub-healthy state. When these hardware enter a sub-healthy state, if the system does not take effective monitoring and fault tolerance measures, it will lead to increased system response delays, packet loss, and even host service interruption due to failure to respond to the host.

[0135] S110. When the communication link detection result indicates that the target node link is abnormal, load a preset program.

[0136] In the embodiment of the present invention, when the communication link detection result indicates that the target node link is abnormal, the detection node loads a preset program.

[0137] Among them, the preset programs may include: Berkeley Packet Filter (BPF). When BPF was first invented, it was a network filtering tool. Now its name has been upgraded to eBPF: extended Berkeley Packet Filter has evolved into a general execution engine. It is no longer just a network analysis tool. Various types of tools and platforms such as performance analysis, system tracing, and network optimization can be developed based on eBPF.

[0138] Among them, eBPF can be implemented by the traffic classifier (TC) and the eXpress Data Path (XDP). TC is an eBPF hook in the Linux network processing flow, which can mount the eBPF program. It provides a variety of functions, such as modifying packets, rerouting, and discarding packets. XDP is an eBPF hook in the Linux network processing flow, which can mount the eBPF program. It can process network data packets when they reach the network card driver layer.

[0139] S111. Determine a switch forwarding rule based on the address resolution protocol table to determine replacement address information in the address resolution protocol table.

[0140] In the embodiment of the present invention, the detection node determines the switch forwarding rule based on the address resolution protocol table to determine the replacement address information in the address resolution protocol table.

[0141] In the embodiment of the present invention, the detection node determines the switch forwarding rule based on the source physical address information and the second source physical address information of each node to be detected in the address resolution protocol table. The detection node determines the replacement address information corresponding to the switch forwarding rule in the address resolution protocol table.

[0142] In an embodiment of the present invention, if the source physical address information of each node to be tested in the address resolution protocol table is inconsistent, the switch forwarding rule obtained by the detection node is the source address forwarding algorithm. If the second source physical address information of each node to be tested in the address resolution protocol table is inconsistent, the switch forwarding rule obtained by the detection node is the destination address forwarding algorithm. If there is inconsistency between the source physical address information and the second source physical address information of each node to be tested in the address resolution protocol table, the switch forwarding rule obtained by the detection node is the source destination address forwarding algorithm.

[0143] In the embodiment of the present invention, the detection node determines the corresponding target source physical address information and target second source physical address information in the address resolution protocol table through the identifier of the target node included in the service message. The detection node determines the replacement address information in the target source physical address information and the target second source physical address information based on the switch forwarding rule; wherein the replacement address information is the address information corresponding to the network port with the smallest load of the target node.

[0144] Among them, if the switch forwarding rule is a source address forwarding algorithm, the detection node determines the replacement address information in the target source physical address information. If the switch forwarding rule is a destination address forwarding algorithm, the detection node determines the replacement address information in the target second source physical address information. If the switch forwarding rule is a source destination address forwarding algorithm, the detection node can determine the replacement address information in the target source physical address information and the target second source physical address information.

[0145] S112, responding to a preset program, using the replacement address information to replace the source address information or the destination address information in the service message according to the switch forwarding rule, and obtaining a target message to send to a target node.

[0146] In the embodiment of the present invention, the detection node responds to a preset program, uses the replacement address information to replace the source address information or the destination address information in the service message according to the switch forwarding rule, and obtains the target message to send to the target node.

[0147] Among them, if the switch forwarding rule is the source address forwarding algorithm, the detection node uses the replacement address information to replace the source address information in the service message. If the switch forwarding rule is the destination address forwarding algorithm, the detection node uses the replacement address information to replace the destination address information in the service message. If the switch forwarding rule is the source-destination address forwarding algorithm, the detection node uses the replacement address information to replace the source address information or the destination address information in the service message.

[0148] In an embodiment of the present invention, when a detection node detects a link failure of a target node, it determines a switch forwarding rule through an address resolution protocol table, and determines an available replacement address information corresponding to the target node in the address resolution protocol table, and uses the replacement address information to modify the source address or destination address in the service message, thereby achieving the effect of sending the target message to the target node.

[0149] See also Figure 4 , which is an optional effect diagram of the data processing method provided in an embodiment of the present invention.

[0150] In an embodiment of the present invention, all servers in the network system ping each other, and each server sends a detection message to other servers. Each server sends a first detection message regularly (such as every second or every minute) through the constructed virtual address information, and determines the address resolution protocol table based on the first response message fed back. When server A detects the packet loss rate or delay between the network port of server B through the current detection message and the current response message, if the packet loss rate or delay is continuously greater than the threshold th1 within a given time period T, the link will be considered sub-healthy, and if it is continuously greater than the threshold th2, the link will be considered to be faulty. When server A detects a link failure / sub-health between network port A1 and network port B1, the control center of the detection node determines a learned virtual mac address in the address resolution protocol table for topology routing (the message with the mac address as the source mac or destination mac will be forwarded by the switch to the healthy network port of server B, such as network port B2). Among them, the address resolution protocol table includes: correspondence 1: source port A1, source mac1, destination port B1; correspondence 2: source port A2, source mac2, destination port B2. Server A now notifies server B to load the eBPF program (TC and XDP). Server A selects a virtual mac address that can be hashed to a healthy destination port (such as port B2). Server A modifies the source mac or destination mac in the service message through the eBPF program and redirects it to a normal port, such as port A2. After server B receives the target message, (such as port B2) it uses eBPF to detect the source mac address or destination mac address in the target message. If the source mac address or destination mac address is a special mac address used for link switching, the source mac address of the target message is modified and restored to the real source mac or destination mac address. When server A detects that the link failure / sub-health has been restored, it uninstalls the eBPF program to restore the communication link.
