In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.

Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.

Definition of terms:

encapsulating Remote Switch Port mirror (Encapsulated Remote Switch Port Analyzer, ERSPAN for short): the method is a network message mirroring mode on the Switch, and is an extension on the basis of a Switch Port Analyzer (span for short), and can match message characteristics to mirror a specific message and send the specific message to a remote server through encapsulation.

Access Control List (ACL): the method is used for matching out a specific message based on message characteristics, and the message characteristics may include: source IP address, destination IP address, source port, destination port, etc.

User Defined Field (UDF for short): ACLs on the switch can only be analyzed and identified based on fixed characteristics, and the UDF can match any characteristics of the message header according to user requirements, including header characteristics of loads and the like.

RoCE (RDMA over converted Ethernet) protocol: is a network protocol that allows Remote Direct Memory Access (RDMA) over ethernet.

The RoCEv2 protocol: the method is an RDMA Protocol based on Ethernet, and is used for data transmission for a User Datagram Protocol (UDP), and specifically uses a UDP port 4791 for transmission.

Negative Acknowledgement (NAK) message: the standard message predefined in the RoCEv2 protocol corresponds to an acknowledgement Character message (ACK), where the ACK message represents feedback after receiving a corresponding message, and the NAK message represents feedback to the transmitting end after not receiving a data packet with a corresponding preset sequence number, and it is desirable that the transmitting end can retransmit all messages after the data packet with the sequence number.

Specifically, as shown in fig. 1, the network includes a network node 1 and a network node 2, the network node 1 may sequentially transmit a data packet 1, a data packet 2, a data packet 3, a data packet 4, and a data packet 5 to the network node 2, and after the network node 2 receives the data packet 1, may send an ACK packet for identifying that the data packet 1 is received to the network node 1.

When the network node 2 does not receive the data packet 2 but directly receives the data packet 3, it indicates that a packet loss situation occurs in the network, at this time, the network node 2 sends a NAK message for identifying the existence of the packet loss situation to the network node 1, and in general, the NAK message includes quintuple information (source IP address, source port, destination IP address, destination port, and transport layer protocol) to inform the network node 1 that the network node 2 does not receive the data packet 2 in network transmission.

After the network node 1 receives the NAK packet for identifying that the network node 2 does not receive the data packet 2, the network node 1 performs a retransmission operation on the data packet 2 and all data packets located behind the data packet 2, that is, the network node 1 performs a retransmission operation on the data packet 2, the data packet 3, the data packet 4, and the data packet 5.

In order to facilitate understanding of the technical solutions of the present application, the following description relates to related technologies:

in a communication network based on a Transmission Control Protocol (TCP), packet loss often occurs due to insufficient cache of a switch. However, since the TCP network configures a relatively perfect retransmission mechanism for the packet loss situation, the TCP network is not affected by the packet loss situation.

For the RoCEv2 network, the application layer of RoCEv2 is an Infiniband (IB) protocol, and since the IB protocol is implemented by credit-based flow control, the network implemented by the IB protocol is a lossless network. At this time, for the lossless network, too many packet loss situations are not considered, so that too many packet loss situations are not considered by the IB protocol, and the retransmission mechanism of the IB is a retransmission mechanism with very low efficiency, and then when packet loss retransmission is performed in the network, the performance of data transmission is greatly affected.

In order to ensure the quality and efficiency of data transmission in a network, the present embodiment provides a node positioning method, apparatus, and device. Specifically, the method comprises the steps of determining a network node to be analyzed in a network, which has data retransmission operation, according to a network retransmission message obtained by the network retransmission message; and then, a target network node with network packet loss is determined in the network nodes to be analyzed, so that the network nodes with network packet loss can be accurately and quickly positioned, and then the operation state of the nodes can be adjusted and maintained based on the positioned network nodes, thereby further reducing the influence of the network packet loss on the data transmission performance and ensuring the quality and efficiency of network operation.

In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.

Fig. 2 is a schematic flowchart of a node positioning method according to an embodiment of the present invention; fig. 3 is a schematic view of a scenario of a node positioning method according to an embodiment of the present invention; referring to fig. 2 to fig. 3, the embodiment provides a node positioning method, where an execution subject of the method is a node positioning apparatus, and when the method is applied specifically, the node positioning apparatus may be implemented as a server, and the server may be implemented as software, or a combination of software and hardware. Specifically, the method may include:

step S201: and acquiring a network retransmission message.

Step S202: and determining the network node to be analyzed with data retransmission operation in the network according to the network retransmission message.

Step S203: and determining a target network node with network packet loss in the network nodes to be analyzed.

The following is a detailed description of the above steps:

step S201: and acquiring a network retransmission message.

The network retransmission packet is a packet for identifying that a network retransmission operation exists in a network, and it can be understood that, when the node location method is applied to different networks generated by different network protocols, the network retransmission packet may be a packet of different standards corresponding to the network protocols, for example: when the node location method is applied to a communication network generated by the RoCEv2 protocol, the network retransmission message may refer to a standard message "first NAK message" defined in the RoCEv2 protocol. When the node location method is applied to a TCP network, the network retransmission packet may refer to a standard packet "second NAK packet" defined in the TCP network.

In addition, the specific implementation manner for obtaining the network retransmission packet is not limited in this embodiment, and those skilled in the art may set the implementation manner according to specific application requirements and design requirements. In the first implementation manner, the network retransmission message may be stored in a preset area, and the network retransmission message may be acquired by accessing the preset area, so that the positioning device may stably and effectively acquire the network retransmission message.

In a second implementation manner, referring to fig. 4, the obtaining of the network retransmission packet in this embodiment may include:

step S2011: network message information of network nodes in a network is obtained, and the network message information is used for identifying the running state of the network nodes.

Step S2012: and in the network message information, acquiring a network retransmission message through a preset extraction instruction, wherein the preset extraction instruction is generated based on a user-defined field.

The network may include a plurality of network nodes, each network node may correspond to respective network packet information, and the network packet information is used to identify an operating state of the network node. The network retransmission packet is at least a part of the network packet information, so that in order to obtain the network retransmission packet, the network packet information of the network node in the network may be obtained first, specifically, the specific obtaining manner of the network packet information is not limited in this embodiment, and a person skilled in the art may set the network retransmission packet according to specific application requirements and design requirements, for example: the network nodes included in the network can be identified first, and then the network message information corresponding to the network nodes is obtained based on the preset instruction. Of course, those skilled in the art may also use other manners to obtain the network packet information of the network node in the network, as long as the accuracy and reliability of obtaining the network packet information can be ensured, which is not described herein again.

After the network packet information is obtained, the network packet information may be analyzed to obtain a network retransmission packet. Specifically, because a part of the network message information is included when the network retransmits the message, in order to accurately identify the network retransmission message, the network retransmission message can be extracted from the network message information through a preset extraction instruction, wherein the preset extraction instruction is generated based on a user-defined field and is used for extracting the network retransmission message from the network message information.

For example, when the network retransmission packet is a standard NAK packet defined in the RoCEv2 protocol, since the NAK packet is a byte content after UDP information, at this time, the network retransmission packet cannot be matched in the network packet information through ACL information, so that a preset extraction instruction for extracting the NAK packet can be generated based on the user-defined field, and the preset extraction instruction can extract the network retransmission packet located at each position (for example, 32 bits or 16 bits) in the network packet information, thereby effectively ensuring the accuracy and reliability of obtaining the network retransmission packet.

In the third implementation manner, the network retransmission packet may be stored in the network device, and the network device is in communication connection with the node positioning device, at this time, the network device may send the network retransmission packet to the positioning device based on the packet acquisition request sent by the positioning device. Or after the network device obtains the network retransmission packet, the network retransmission packet may be actively mirrored to the positioning device, and at this time, the positioning device may receive the network retransmission packet sent by the network device through mirroring operation.

For example, when the network device is a switch, the switch may obtain and store a network retransmission packet. At this time, obtaining the network retransmission packet may include: the positioning device can receive the network retransmission message sent by the switch through the mirroring operation, so that the positioning device can stably and effectively acquire the network retransmission message.

For the switch, acquiring the network retransmission packet may include: network message information of network nodes in a network is obtained, and the network message information is used for identifying the running state of the network nodes. In the network message information, a network retransmission message is obtained through a preset extraction instruction, and the preset extraction instruction is generated based on a user-defined field. The implementation manner and the implementation effect of each step in this embodiment are similar to those of steps S2011 to S2012 in the above embodiment, and reference may be specifically made to the above statements, which are not repeated herein.

In brief summary, the implementation scheme of the second implementation mode is as follows: and the positioning device acquires the network message information of the network nodes in the network, and then extracts the network retransmission message from the network message information. The third implementation scheme is as follows: the switch acquires network message information of network nodes in a network, extracts network retransmission messages from the network message information, and mirrors the acquired network retransmission messages to the positioning device, so that the positioning device can acquire the network retransmission messages.

As can be seen from comparison, for the node location device, the data processing amount of the third implementation manner is much smaller than that of the second implementation manner, and therefore, in a specific application, it is preferable to obtain the network retransmission packet through the third implementation manner.

After the network retransmission packet is obtained, the network retransmission packet may be analyzed to determine a network node to be analyzed where a data retransmission operation occurs in the network, and it may be understood that the network node to be analyzed may include a sending node and a receiving node corresponding to the data retransmission operation.

In addition, the embodiment does not limit the specific implementation manner of determining the network node to be analyzed where the data retransmission operation occurs in the network according to the network retransmission packet, and a person skilled in the art may set the network node to be analyzed according to specific application requirements and design requirements, for example: the machine learning model used for determining the network node to be analyzed is trained in advance, and after the machine learning model is obtained, the machine learning model can be used for analyzing and processing network retransmission messages so as to determine the network node to be analyzed with data retransmission operation in the network. Or, the preset requirements met by the network node to be analyzed are obtained, and then the network node meeting the preset requirements in the network can be determined as the network node to be analyzed based on the network retransmission message.

Of course, those skilled in the art may also use other manners to determine the network node to be analyzed where the data retransmission operation occurs in the network according to the network retransmission packet, as long as the accuracy and reliability of determining the network node to be analyzed can be ensured, which is not described herein again.

The network nodes to be analyzed may include a network node with network packet loss and a network node without network packet loss, so after the network nodes to be analyzed are obtained, the target network node with network packet loss may be determined in the network nodes to be analyzed. Specifically, the embodiment does not limit the specific implementation manner of determining the target network node where the network packet loss occurs, and a person skilled in the art may set the network node according to specific application requirements and design requirements, for example: after the network node to be analyzed is obtained, retransmission characteristic information corresponding to the network node to be analyzed may be determined based on a network retransmission packet, where the retransmission characteristic information may include a characteristic value for identifying a retransmission operation degree; after the retransmission characteristic information is obtained, the target network node with the network packet loss can be determined based on the retransmission characteristic information, so that the network node with the network packet loss can be accurately and quickly positioned.

For example, referring to fig. 3, the network includes a network node 1, a network node 2, a network node 3, a network node 4, a network node 5, a network node 6, and a network node 7, where the network node 1 is communicatively connected to the network node 2 and the network node 7, and the network node 1 is configured to send a data packet to the network node 2 and the network node 7. Network node 2 is communicatively coupled to network node 3 and network node 4, and network node 2 is configured to send data packets to network node 3 and network node 4. The network node 4 is in turn communicatively connected to a network node 5 and a network node 6, and the network node 4 is configured to send data packets to the network node 5 and the network node 6.

Specifically, for the network node 1, it cannot receive a data packet sent by another network node, and when the network node 1 sends a data packet to the network node 2 and the network node 7, and when the network node 2 and the network node 7 cannot normally receive the data packet, the network node 1 needs to perform a retransmission operation on the network node 2 and the network node 7, for example: the network node 1 retransmits the data packet to the network node 2 to generate retransmission data 1; the network node 1 retransmits the data packet to the network node 7, resulting in retransmitted data 3.

For the network node 4, after the network node 4 receives the data packet sent by the network node 2, the data packet may be sent to the network node 5, and when the network node 5 does not receive the data packet, the network node 4 needs to perform a retransmission operation on the network node 5 to generate the retransmission data 2.

After acquiring the retransmission data 1, the retransmission data 2, and the retransmission data 3, a network retransmission packet may be generated based on the retransmission data 1, the retransmission data 2, and the retransmission data 3. After obtaining the network retransmission packet, the network node to be analyzed may be determined based on the network retransmission packet, for example: the network nodes to be analyzed may include network node 1, network node 2, network node 4, network node 5, and network node 7. After the network node to be analyzed is obtained, retransmission feature information corresponding to the network node to be analyzed may be determined, for example: the retransmission feature information corresponding to the network node 1 is 2, and the retransmission feature information corresponding to the network node 2, the network node 7, the network node 4, and the network node 5 is 1.

After the network node to be analyzed and the retransmission characteristic information are obtained, a target network node with network packet loss can be determined in the network node to be analyzed based on the retransmission characteristic information, for example, the network node 1 is determined as the target network node, so that the network node with network packet loss can be accurately and quickly located.

According to the node positioning method provided by the embodiment, the network retransmission message is acquired, and the network node to be analyzed, in which the data retransmission operation occurs, in the network is determined according to the network retransmission message, so that the target network node in which the network packet loss occurs is determined in the network node to be analyzed, and thus, the network node in which the network packet loss occurs can be effectively and quickly positioned, so that the operation state of the node is adjusted and maintained based on the positioned network node, the influence of the network packet loss on the data transmission performance is further reduced, the network operation quality and efficiency are ensured, and the practicability of the method is improved.

Fig. 5 is a schematic flowchart of a process of determining a network node to be analyzed, where a retransmission operation occurs in a network, according to a network retransmission packet according to an embodiment of the present invention; on the basis of the foregoing embodiment, with reference to fig. 5, in this embodiment, a specific implementation manner of determining, according to a network retransmission packet, a network node to be analyzed where a retransmission operation occurs in a network is not limited, and a person skilled in the art may set the network node to be analyzed according to a specific application requirement and a design requirement, which is preferable, and determining, according to the network retransmission packet, the network node to be analyzed where the retransmission operation occurs in the network in this embodiment may include:

step S501: and determining retransmission characteristic information corresponding to the network nodes in the network based on the network retransmission message.

Step S502: and determining the network nodes to be analyzed with data retransmission operation in the network according to the retransmission characteristic information.

In order to determine a network node to be analyzed in a network based on a network retransmission packet, after the network retransmission packet is obtained, the network retransmission packet may be analyzed to determine retransmission feature information corresponding to the network node in the network, where the retransmission feature information may include: the IP address of the source corresponding to the sending node, the IP address of the target corresponding to the receiving node, and the characteristic value used for identifying the retransmission operation degree, where optionally, the characteristic value used for identifying the retransmission operation degree may include the number of retransmission operations occurring in a preset time period by the network node.

After the retransmission feature information is obtained, analysis processing may be performed on the retransmission feature information to determine a network node to be analyzed where data retransmission operation occurs in the network, specifically, as shown in fig. 6, in this embodiment, determining, according to the retransmission feature information, a network node to be analyzed where data retransmission operation occurs in the network may include:

step S601: and analyzing and comparing the characteristic value with a preset characteristic threshold value, wherein the preset characteristic threshold value is used for identifying the minimum limit value of the data retransmission operation of the network node.

Step S602: and when the characteristic value is greater than or equal to the preset characteristic threshold value, determining the network node to be analyzed based on the sending node and the receiving node corresponding to the characteristic value.

When the retransmission characteristic information includes a characteristic value for identifying the retransmission operation degree, the characteristic value may be analyzed and compared with a preset characteristic threshold, and the preset characteristic threshold is used to identify a minimum limit value of a data retransmission operation occurring in the network node, so that when the characteristic value is greater than or equal to the preset characteristic threshold, the network node to be analyzed may be determined based on the sending node and the receiving node corresponding to the characteristic value, specifically, the sending node and the receiving node corresponding to the characteristic value may be directly determined as the network node to be analyzed, thereby effectively ensuring the accuracy and reliability of determining the network node to be analyzed.

In the embodiment, retransmission characteristic information corresponding to the network node in the network is determined based on the network retransmission message, and then the network node to be analyzed with data retransmission operation in the network is determined according to the retransmission characteristic information, so that the accuracy and reliability of determining the network node to be analyzed are effectively ensured, and the stability and reliability of the method are further improved.

Fig. 7 is a schematic flowchart of a process of determining a target network node with network packet loss in a network node to be analyzed according to an embodiment of the present invention; on the basis of the foregoing embodiment, with reference to fig. 7, in this embodiment, a specific implementation process of determining a target network node with a network packet loss is not limited, and a person skilled in the art may set the process according to specific application requirements and design requirements, and preferably, in the network node to be analyzed in this embodiment, determining the target network node with the network packet loss may include:

step S701: the method comprises the steps of obtaining a first network node and a second network node which are used for carrying out data transmission operation and are included in network nodes to be analyzed.

Step S702: and when the plurality of first network nodes and the same second network node are the network nodes to be analyzed, determining a target network node with network packet loss based on the second network node.

After the network node to be analyzed is obtained, analyzing the network node to be analyzed to obtain a first network node and a second network node which are included in the network node to be analyzed and used for performing data transmission operation, wherein the first network node may include a sending node used for sending data, and the second network node may include a receiving node used for receiving data; alternatively, the second network node may comprise a sending node for sending data and the first network node may comprise a receiving node for receiving data.

After the first network node and the second network node included in the network node to be analyzed are obtained, the first network node and the second network node may be analyzed to determine a target network node where a network packet loss occurs. For example, when a plurality of first network nodes and the same second network node are both network nodes to be analyzed, a target network node where network packet loss occurs may be determined based on the second network node.

Optionally, referring to fig. 8, in this embodiment, determining, by the second network node, a target network node where the network packet loss occurs may include:

step S801: and acquiring a node retransmission message corresponding to the second network node.

Step S802: and detecting whether the self data transmission state of the second network node is normal or not based on the node retransmission message.

Step S803: and when the self data transmission state of the second network node is a normal state, determining the uplink port of the second network node as the target network node for determining the occurrence of network packet loss. Alternatively, the first and second electrodes may be,

step S804: and when the data transmission state of the second network node is an abnormal state, determining a target network node with network packet loss based on the second network node.

When the plurality of first network nodes and the same second network node are both the network nodes to be analyzed, it is indicated that data transmission operation between the second network node and other first network nodes is abnormal, and/or data transmission operation of the second network node itself is abnormal.

At this time, in order to accurately identify the target network node where the network packet loss occurs, the node retransmission packet corresponding to the second network node may be acquired. Specifically, the network retransmission packet includes node retransmission packets corresponding to each network node, and after the second network node is determined, the node retransmission packet corresponding to the second network node may be determined in the network retransmission packet based on a node identifier corresponding to the second network node, where the node retransmission packet is used to identify a retransmission feature of the node retransmission operation performed by the second network node.

The node retransmission message may include: the first identification information of the data transmission state between the current node and other nodes and the second identification information of the data transmission state of the current node can further detect whether the data transmission state of the second network node is normal or not based on the second identification information.

When detecting whether the self data transmission state of the second network node is normal based on the second identification information, in an implementable manner, standard identification information for identifying that the self data transmission state of the second network node is a normal state may be obtained, and the second identification information and the standard identification information are analyzed and compared to achieve determination of a target network node with network packet loss based on the second network node.

When the second identification information is matched with the standard identification information, it is indicated that the self data transmission state of the second network node is a normal state, and the data transmission operation between the second network node and other first network nodes is abnormal, so that the uplink port of the second network node can be determined as a target network node for determining that network packet loss occurs, and the uplink port of the second network node is used for performing data transmission operation with other first network nodes.

When the second identification information is not matched with the standard identification information, it indicates that the data transmission state of the second network node is an abnormal state, and the target network node with network packet loss can be further determined based on the second network node.

Optionally, as shown in fig. 9, the determining, based on the second network node, the target network node where the network packet loss occurs may include:

step S901: traversing the sub-network nodes comprised by the second network node.

Step S902: and determining a target network node with network packet loss based on the traversed sub-network nodes and the second network node.

The second network node may comprise one or more sub-network nodes, and in particular implementations, the second network node may comprise a switch and the sub-network node comprises a server communicatively coupled to the switch. When the own data transmission state of the second network node is determined to be the abnormal state, the fact that the own data transmission state of the second network node is the abnormal state may be caused based on the operation abnormality of the sub-network node. Therefore, in order to accurately identify the target network node, the sub-network node included in the second network node may be obtained first, and specifically, the sub-network node included in the second network node may be determined based on the network architecture corresponding to the second network node. After acquiring the sub-network node included in the second network node, a target network node where a network packet loss occurs may be determined based on the traversed sub-network node and the second network node.

Optionally, as shown in fig. 10, in this embodiment, determining, based on the traversed sub-network node and the second network node, a target network node where a network packet loss occurs may include:

step S1001: acquiring a child node retransmission message corresponding to the traversed child network node;

step S1002: detecting whether the data transmission state of the sub-network node is normal or not based on the retransmission message of the sub-node;

step S1003: when the data transmission state of the sub-network node is a normal state, determining the second network node as a target network node with network packet loss; alternatively, the first and second electrodes may be,

step S1004: and when the data transmission state of the sub-network node is in an abnormal state, determining the sub-network node as a target network node with network packet loss.

In order to accurately identify the target network node with network packet loss, after traversing the sub-network nodes included in the second network node, the sub-node retransmission packet corresponding to the traversed sub-network node may be acquired. Specifically, the node retransmission message corresponding to the second network node includes child node retransmission messages corresponding to the respective child network nodes, and after all the child network nodes included in the second network node are determined, the child node retransmission message corresponding to the traversed child network node may be determined in the node retransmission message based on the child node identifier corresponding to the child network node, where the child node retransmission message is used to identify the retransmission feature of the child network node for performing the node retransmission operation.

After the child node retransmission message is acquired, since the child node retransmission message is used for identifying the current data transmission state of the child network node, whether the data transmission state of the child network node is normal can be detected based on the child node retransmission message.

When the sub-network node detects whether the data transmission state of the sub-network node is normal based on the sub-node retransmission message, an achievable mode is that standard characteristic information for identifying that the data transmission state of the second network node is normal can be obtained, and the retransmission characteristic information in the sub-node retransmission message is analyzed and compared with the standard characteristic information, so that whether the data transmission state of the sub-network node is normal based on the sub-node retransmission message is detected.

When the retransmission characteristic information in the retransmission message of the child node matches the standard characteristic information, it indicates that the data transmission state of the child network node is a normal state, and further, when the data transmission states of all the child network nodes traversed in the second network node are normal states, the second network node may be determined as a target network node with network packet loss.

When the retransmission characteristic information in the retransmission message of the sub-node is not matched with the standard identification information, the data transmission state of the sub-network node is an abnormal state, and the sub-network node can be determined as the target network node with the network packet loss, so that the accuracy and reliability of determining the target network node with the network packet loss are effectively realized.

In this embodiment, by obtaining the network nodes to be analyzed including the first network node and the second network node for performing the data transmission operation, and then determining the target network node with the network packet loss based on the second network node when the plurality of first network nodes and the same second network node are both the network nodes to be analyzed, the determination of the target network node is effectively achieved by comprehensively considering various operating conditions related to the second network node, so that the accuracy and reliability of determining the target network node with the network packet loss are effectively ensured.

Fig. 11 is a schematic flowchart of a process of determining a target network node where a network packet loss occurs in a network node to be analyzed according to an embodiment of the present invention; on the basis of any one of the foregoing embodiments, with reference to fig. 11 continuously, the present embodiment provides a target network node for determining that a network packet loss occurs, specifically, in a network node to be analyzed in the present embodiment, the determining of the target network node for determining that the network packet loss occurs may include:

step S1101: and acquiring the quantity information of the network nodes to be analyzed.

Step S1102: and when the quantity information is greater than or equal to the preset quantity threshold value, identifying a first transmission state between any network node to be analyzed and other network nodes to be analyzed and a second transmission state corresponding to the network node to be analyzed.

Step S1103: and determining the target network node with network packet loss according to the first transmission state and the second transmission state.

After the network nodes to be analyzed are obtained, the number information of the network nodes to be analyzed can be counted and obtained, then the number information can be analyzed and compared with a preset number threshold, and when the number information is larger than or equal to the preset number threshold, the number of the network nodes with data retransmission operation in the network is large. At this time, the abnormal situation occurring in the network may be caused by: a parent network node corresponding to the network node to be analyzed, or caused by a global fault of the network.

In order to accurately identify the specific situation of the network with the abnormality, a first transmission state between any network node to be analyzed and other network nodes to be analyzed and a second transmission state corresponding to the network node to be analyzed can be identified, and then the first transmission state and the second transmission state can be analyzed, so that the target network node with the network packet loss can be determined according to the first transmission state and the second transmission state.

Optionally, determining, according to the first transmission state and the second transmission state, the target network node where the network packet loss occurs may include:

step S11031: when the first transmission state between the network node to be analyzed and other network nodes to be analyzed is an abnormal state and the second transmission state corresponding to the network node to be analyzed is a normal state, acquiring a father network node corresponding to the network node to be analyzed, and determining the father network node as a target network node with network packet loss. Alternatively, the first and second electrodes may be,

step S11032: and when the first transmission state between the network node to be analyzed and other network nodes to be analyzed is an abnormal state, and the second transmission state corresponding to the network node to be analyzed is an abnormal state, determining the network global fault.

After a first transmission state between any network node to be analyzed and other network nodes to be analyzed and a second transmission state corresponding to the network node to be analyzed are obtained, the first transmission state and the second transmission state may be analyzed to determine a target network node with network packet loss.

Specifically, when the first transmission state is an abnormal state and the second transmission state is a normal state, that is, the data transmission state among the plurality of network nodes to be analyzed in the network is a normal state at this time, the parent network node corresponding to the network node to be analyzed is the abnormal state in the network at this time, and then the parent network node corresponding to the network node to be analyzed is acquired. It can be understood that the number of the parent network nodes may be one or more, and after the parent network nodes are acquired, the parent network nodes may be determined as target network nodes where network packet loss occurs.

When the first transmission state is an abnormal state and the second transmission state is an abnormal state, that is, the data transmission state between the plurality of network nodes to be analyzed in the network is an abnormal state at this time, and the data transmission state corresponding to the network node to be analyzed is also an abnormal state, it may be determined that the network at this time is a network global fault.

Optionally, after determining the network global fault, the method in this embodiment may further include: and generating alarm information for identifying the network global fault, timely prompting the network global fault to a user through the alarm information, and debugging or maintaining the network based on the alarm information.

In the embodiment, by acquiring the quantity information of the network nodes to be analyzed, and when the quantity information is greater than or equal to a preset quantity threshold, a first transmission state between any one network node to be analyzed and other network nodes to be analyzed and a second transmission state corresponding to the network node to be analyzed are identified; and then, the target network node with the network packet loss is determined according to the first transmission state and the second transmission state, so that the target network node with the network packet loss is determined by comprehensively considering each operation condition in the network, and the accuracy and reliability of determining the target network node are further improved.

In a specific application, the present application embodiment provides a node locating method, where the method may identify a network device in which a packet loss operation occurs in a network, where the network may include one or more switches, and at this time, the method may identify a switch in which a network packet loss occurs in the network. Or, the network may include one or more aggregation switches, where the aggregation switch is configured to manage one or more switches, and at this time, the method may identify an aggregation switch in which a network packet loss occurs in the network. Or, the network may include one or more servers, and the switch is configured to manage the one or more servers to implement data processing operations, where the method may identify a server in the network where a network packet loss occurs.

In the following, a switch is taken as an example for explanation, and the method may include:

step 1: and acquiring a network retransmission message NAK message in the network.

The NAK message includes active IP information (source switch), a destination IP address (destination switch), and a characteristic value for identifying the retransmission operation degree.

Step 2: and constructing a mapping relation for identifying the running state of the switch in the network based on the source IP information, the destination IP address and the characteristic value in the NAK message.

Specifically, the constructed mapping relationship may include a NAK matrix map, as shown in fig. 12-13, constructed based on the source IP information, the destination IP address, and the characteristic value included in the NAK packet, where each mesh in the NAK matrix map is used to identify the characteristic value between the source IP information and the destination IP information.

Optionally, after obtaining the feature values between the source IP information and the destination IP information, the feature level to which the feature values belong may be determined, and then the grid in the NAK matrix map may be filled with corresponding colors based on the feature level.

For example, three feature levels are preconfigured: the method comprises a characteristic level a, a characteristic level b and a characteristic level c, wherein the characteristic level a is used for identifying that a characteristic value between source IP information and destination IP information is in a normal state, the characteristic level b is used for identifying that the characteristic value between the source IP information and the destination IP information is in a first abnormal state, the characteristic level c is used for identifying that the characteristic value between the source IP information and the destination IP information is in a second abnormal state, and the abnormal degree of the second abnormal state is higher than that of the first abnormal state.

After the feature values between the source IP information and the destination IP information are obtained, the feature level corresponding to the feature values may be determined, and when the feature level corresponding to the feature values is the feature level a, the grid corresponding to the feature values may be filled with a first color (for example, green); when the feature level corresponding to the feature value is the feature level b, the grid corresponding to the feature value may be filled with a second color (e.g., orange); when the feature level corresponding to the feature value is the feature level c, the grid corresponding to the feature value may be filled with a third color (e.g., red).

As shown in fig. 13, the partial grids corresponding to the source IP information 6 (the destination IP information is 1-4, 7-9, 11-15) are filled with the third color, and the partial grids corresponding to the destination IP information 10 (the source IP information is 1-5, 7-8, 11-15) are filled with the third color, so that the data transmission state between each source IP information and the destination IP information can be intuitively and accurately obtained through the NAK matrix diagram.

And step 3: and determining the network nodes to be analyzed with data retransmission operation in the network based on the mapping relation for identifying the running state of the switch in the network.

Specifically, the network node whose characteristic value between the source IP information and the destination IP information is greater than or equal to the preset threshold value may be determined as the network node to be analyzed.

And 4, step 4: and determining a target network node with network packet loss in the network nodes to be analyzed.

Specifically, determining the target network node where the network packet loss occurs may include the following steps:

step 41: looking up a NAK matrix diagram, and when NAK messages exist between a plurality of switches and the same switch, indicating that the corresponding switch has an abnormal condition, wherein the abnormal condition of the switch may include: the switch itself operates abnormally, and/or a server located under the switch operates abnormally.

The switches may correspond to a plurality of source IP messages or a plurality of destination IP messages, and correspondingly, the same switch may correspond to one destination IP message or one source IP message.

Step 42: in order to accurately identify the type of the abnormal condition of the switch, whether the data transmission state of the switch comprises a NAK message or not can be detected, if the data transmission state of the switch does not comprise the NAK message, the switch operates normally, and then the uplink port of the switch can be determined as a target network node for determining the occurrence of network packet loss.

Step 43: if the data transmission state of the switch itself includes the NAK message, it indicates that the switch itself is operating abnormally, and at this time, the abnormal state of the switch may be caused by an abnormality of a server under the switch.

Step 44: in order to accurately identify whether the abnormal state of the switch is caused by the abnormality of a certain server located under the switch, all servers included in the switch can be traversed, and then whether the data transmission states of all the servers are normal is identified, and if the data transmission states of all the servers are determined to be normal, the abnormal state of the switch can be determined to be caused by the switch. When the data transmission state of one or more servers in all the servers is determined to be an abnormal state, the one or more servers can be determined to be the target network node.

Step 45: after the NAK matrix map is obtained, the number information of the switches in which the data retransmission operation occurs in the NAK matrix map may be counted, and when the number information is greater than or equal to a preset number threshold (e.g., 1, 2, or 3, etc.), the network exception at this time may be caused by a failure of an aggregation switch (for managing one or more switches) corresponding to the switch, or based on a network global failure.

Step 46: in order to accurately identify the specific type of the network anomaly, the data transmission state of the switch itself and the data transmission state between the switch and other switches can be acquired.

Step 47: when the data operation state of the switch is a normal state and the data transmission state between the switch and another switch is an abnormal state, it may be determined that the network abnormality is caused by a failure of the aggregation switch (used for managing one or more switches) corresponding to the switch, and then the aggregation switch may be determined as a target network node where a network packet loss occurs.

And 48: when the data operation state of the switch is an abnormal state and the data transmission state between the switch and other switches is an abnormal state, it may be determined that the network abnormality is caused based on the network global fault, and then the network global fault is determined.

And 5: after determining the target network node, the target network node may be controlled to be turned off so that data in the network may be transmitted through other network nodes in the network.

The node positioning method provided by the application embodiment determines a network node to be analyzed, in which data retransmission operation occurs, in a network according to a network retransmission message obtained by obtaining the network retransmission message; and then, in the network nodes to be analyzed, the target network nodes with network packet loss are determined, so that the network nodes with the packet loss in the network can be accurately and quickly positioned, and then the operation state of the nodes can be adjusted and maintained based on the positioned target network nodes, thereby being beneficial to reducing the influence of the network packet loss on the performance of data transmission and ensuring the quality and the efficiency of network operation.

Specifically, the method may include:

step S1601: a network transmission request for a network node is obtained.

Wherein the network node may comprise at least one of: a sending node for implementing data sending operation; a receiving node for implementing a data receiving operation.

Step S1602: and determining the target network node with network packet loss according to the network transmission request.

After the network transmission request is obtained, all network nodes included in the network may be analyzed based on the network transmission request to determine a target network node where a network packet loss situation occurs.

Or, if a network link for implementing the data transmission operation does not include the target network node, the network link may be controlled to perform a normal data transmission operation. Or, a network link for implementing data transmission operation includes a target network node, in order to ensure quality and efficiency of data transmission, a standby network node corresponding to the target network node may be acquired, the data transmission operation is implemented through the standby network node, and prompt information for identifying that the network link includes the target network node may be sent to a user, so that the user may adjust and maintain the network link in time.
