Description

Technical Field

[0001] The present invention relates to the field of network communication, and in particular to a network status detection method, device, equipment and medium. Background Art

[0002] With the rapid development of information technology, the network has become the core infrastructure of modern large and medium-sized enterprises, supporting the daily operation and data processing of enterprises. The state in which the network can operate normally and recover quickly after being impacted by the outside world is called a healthy state; the state in which the network is paralyzed and cannot operate normally is called a sub-healthy state.

[0003] The networks of many large and medium-sized enterprises are in a sub-healthy state. Networks in this state can operate normally, but their ability to resist risks is extremely low. When they are subject to sudden network risks, they are easily paralyzed and difficult to recover for a long time, which will cause the distributed system to enter a state of low performance.

[0004] In related technologies, a client / server architecture is usually used to detect whether the network is in a sub-healthy state, that is, the client sends a detection message to the server, and the server immediately returns the message after receiving the message. After the client collects the returned message, it can calculate the delay and packet loss on the entire link from the client to the server based on the time tag and the number of sent and received messages, thereby making a preliminary assessment of the network status. This method can reflect the current state of the network to a certain extent, but it cannot determine the fault condition of the network. Summary of the invention

[0053] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the present invention.

[0054] It should be noted that in the optional embodiments of the present invention, the object information and other related data involved, when the embodiments of the present invention are applied to specific products or technologies, need to obtain the permission or consent of the object, and the collection, use and processing of the relevant data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0057] For ease of understanding, an embodiment of the present invention provides a scenario diagram of a method for detecting sub-health in a network, such as Figure 1 As shown in the figure, it includes: node 1 (client device), switch and node 2 (server device). On the basis of the original network sub-health detection, target protocol messages are added, such as BFD detection messages. That is, in the time series, after the original network sub-health detects that there is a network sub-health problem, the sending of BFD detection messages is triggered to narrow the scope of the problem.

[0058] Taking the BFD protocol as an example, the embodiment of the present invention proposes a method for detecting and processing network sub-health based on the extended BFD protocol. First, according to the original network sub-health detection logic, the C / S architecture is used to detect delay and packet loss. When it is found that the delay and / or packet loss exceeds the threshold, the BFD protocol (SMP protocol) is immediately re-judged, that is, a two-way forwarding detection protocol message is created and sent to the outside to detect whether there is a problem from the node to the switch. If there is also packet loss in the two-way forwarding detection protocol message, the node system status is immediately re-judged, that is, whether there is a problem with the node resources (CPU, memory, network). According to the above logic, it can be determined whether the fault is in the Client node or in the link from the Client to the switch. Through the above logic, the specific problem point can be quickly located, the accuracy of network sub-health detection is improved, the probability of misjudging the packet loss exceeding the threshold is reduced, and the operation and maintenance efficiency can also be improved.

[0059] Specifically, an embodiment of the present invention provides a network status detection method, such as Figure 2As shown, the method provided in the embodiment of the present invention can be executed by an electronic device, and the electronic device is a server. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited to this. The terminal device and the electronic device can be directly or indirectly connected through wired or wireless communication, and the embodiment of the present invention is not limited here. The method includes:

[0060] S101, obtaining network performance of a target network link, where the target network link includes: an electronic device, a switch, and a target device;

[0061] The target network link is used to realize data transmission between the electronic device and the target device. When the electronic device is a client device, the target device is a server; when the electronic device is a server, the target device is a client device. The switch is used to forward data packets and connect different electronic devices and target devices through multiple ports. Network performance includes but is not limited to bandwidth, delay, packet loss rate, and jitter, which can reflect the performance of the target network link, such as transmission capacity, response speed, and stability.

[0062] S102, determining whether the target network link is in a sub-healthy state according to the network performance of the target network link;

[0063] In the embodiment of the present invention, the network performance is monitored to see whether it exceeds a threshold value. If it exceeds the threshold value, it indicates that the network is in a sub-healthy state.

[0064] S103, if the target network link is in a sub-healthy state, a target protocol message is sent to the switch, and the target protocol message is used to make the switch return a target protocol feedback message;

[0065] The target protocol message is a bidirectional forwarding detection protocol message or an icmp protocol message.

[0066] Bfd (Bidirectional Forwarding Detection) provides a general, standardized, media-independent and protocol-independent fast fault detection mechanism for fast detection and monitoring of the forwarding connectivity of links or IP routes in the network. The icmp protocol message (Internet Control Message Protocol) is part of the Internet protocol suite and is used to transmit control messages between IP hosts and routers.

[0067] When a sub-healthy network state is detected, the electronic device will automatically send the target protocol message and receive the feedback message from the switch. The communication process of the entire target link is divided into at least two small segments, and then the fault is determined for a certain small segment. By gradually narrowing the fault area, accurate fault location can be performed.

[0068] In some embodiments, the electronic device sends a target protocol message with a first timestamp and requires the switch to reply with a response with a second timestamp of received data and a third timestamp of returned data, so as to determine the delay and packet loss through these timestamps.

[0069] S104: Determine the status of each device of the target network link according to the packet loss information of the target protocol feedback message and the node resource information of the electronic device.

[0070] Packet loss information indicates whether information is lost or not successfully received during transmission based on the target protocol feedback message. The status of each device in the target network link refers to the current working status of each node (i.e., electronic device, switch, and target device) in the target network link, including whether it is operating normally (healthy status), whether there is a fault, etc.

[0071] It is understandable that in the process of network communication, in order to ensure reliable data transmission and stable operation of the network, it is necessary to constantly monitor the status of the network link. If the electronic device can receive information fed back by the switch, the status of the switch can be determined as a healthy state. At this time, it is necessary to pay attention to the node resource information of the electronic device to determine whether the electronic device is in a healthy state; since the target network link is currently in a sub-healthy state, if the electronic device is also in a healthy state, the target device is in a sub-healthy state. Through simple judgment, the location of the fault can be preliminarily located, so that the technicians can carry out targeted maintenance.

[0072] It can be seen that in the embodiment of the present invention, the network performance of the target network link is obtained, and based on the network performance data, it can be accurately determined whether the target network link has entered a sub-healthy state of the network; when the sub-healthy state is detected, a small-scale detection is performed, specifically the detection of the electronic device to the switch link, wherein the electronic device will quickly send the target protocol message to the switch, and use the target protocol feedback message returned by the switch and the node resource information of the electronic device to comprehensively evaluate the specific status of each device on the target network link, which not only realizes real-time monitoring of the network status, but also can quickly determine the fault condition.

[0073] A possible implementation of the embodiment of the present invention, S104, determining the state of each device of the target network link according to the packet loss information of the target protocol feedback message and the node resource information of the electronic device, includes:

[0074] S1041. If the packet loss information indicates that there is no packet loss, determine that the state of the target device is a sub-healthy state.

[0075] Among them, if there is no packet loss, it means that the link between the electronic device and the switch is normal, and both are in a healthy state. However, since the target network link is in a sub-healthy state, the state of the target device is predicted to be a sub-healthy state.

[0076] S1042: If the packet loss information indicates that there is packet loss and the packet loss rate is not 1, determining that the state of the switch is a healthy state, and determining whether the state of the electronic device is a healthy state based on the node resource information of the electronic device;

[0077] In an embodiment of the present invention, if there is packet loss, if all packets are lost, that is, the packet loss rate is 1, at this time, it cannot be determined whether it is an electronic device failure or a switch failure. It can be judged in combination with the network performance of the target network link. If at least one feedback message can be obtained during the preliminary judgment, it means that the switch can work. At this time, the state of the switch is determined to be normal, and the state of the electronic device is sub-healthy; if no feedback message is received during the preliminary judgment, a prompt message is generated to facilitate manual confirmation by the technician.

[0078] If there is packet loss and the packet loss rate is not 1, it means that the switch can operate normally and the switch status is determined to be healthy. At this time, since the target network link is in a sub-healthy state, it may be that the electronic device is in a sub-healthy state and / or the target device is in a sub-healthy state. Obtain the node resource information of the electronic device, such as CPU, memory, and network, so as to determine the status of the electronic device based on the node resources.

[0079] Specifically, the status of the electronic device may be determined in combination with multiple dimensions of the node resource information.

[0080] In some embodiments, thresholds corresponding to multiple dimensions are pre-set, such as CPU usage not exceeding a first threshold, such as 80%, memory usage not exceeding a second threshold, such as 70%, remaining storage space not less than a third threshold such as 10%, network excellence not less than a fourth threshold, etc.; threshold matching is performed on the collected node resource information, and if all dimensions meet the corresponding thresholds, the device is determined to be in a healthy state; otherwise, it is determined to be in a sub-healthy state.

[0081] S1043: If the state of the electronic device is a healthy state, determine that the state of the target device is a sub-healthy state.

[0082] If the status of the electronic device is healthy, the status of the switch is healthy, and the target network link is in a sub-healthy state, then the status of the target device is in a sub-healthy state.

[0083] S1044, if the state of the electronic device is a sub-healthy state, optimizing the resource information of the electronic device so that the state of the electronic device is a healthy state;

[0084] If the state of the electronic device is sub-healthy, the state of the target device is unclear. In one achievable manner, the resource information of the electronic device can be optimized first so that its resource information conforms to the resource information range in a healthy state, and the state of the electronic device is healthy.

[0085] Furthermore, a target protocol message may be sent to the switch; if the second packet loss information of the target protocol feedback message indicates that there is no packet loss, it is determined that the current state of the electronic device is a healthy state.

[0086] S1045. Obtain new network performance of the target network link; determine whether the target network link is in a sub-healthy state based on the new network performance of the target network link; if the target network link is in a sub-healthy state, determine that the target device is in a sub-healthy state; if the target network link is not in a sub-healthy state, determine that the target device is in a healthy state.

[0087] A possible implementation of the embodiment of the present invention includes sending a target protocol message to a switch, including:

[0088] Divide the current period into multiple sub-periods;

[0089] Sending a target protocol message to the switch at a first frequency in a first sub-period;

[0090] If the sub-packet loss information of the first sub-period indicates that there is no packet loss, the target protocol message is sent to the switch at the second frequency in the next sub-period; the second frequency is greater than the first frequency; otherwise, the target protocol message is sent to the switch at the first frequency in the next sub-period; until the sending of the target protocol message in the current period is completed.

[0091] Among them, the current time period is the current time period that needs to detect the target network link. The current time period is subdivided into multiple smaller sub-periods, such as the current time period is 8:01-8:03, divided into 8:01-8:02, 8:02-8:03. The first frequency and the second frequency respectively represent two different sending rates used when sending the target protocol message. The first frequency is the regular sending frequency, and the second frequency is higher, indicating that the network condition is good and there is no packet loss in the previous sub-period. Increase the amount of message sending to improve communication efficiency.

[0092] The current time period is divided into multiple sub-periods, and the time length of each sub-period can be the same or different, which is not limited in the embodiment of the present invention. In the first sub-period, the target protocol message is sent to the switch at a first frequency; if there is no packet loss in the first sub-period, it means that the current network condition is good, so in the next sub-period, the sending frequency is increased, and the target protocol message is sent to the switch at a second frequency. If packet loss occurs in the first sub-period, it means that the current network condition may be poor, and the original sending frequency is maintained in the next sub-period, and the target protocol message is sent to the switch until all the target protocol messages in the current period are sent. The increased frequency can be increased in sequence according to the fixed frequency difference until the frequency reaches the preset frequency threshold.

[0093] It can be seen that in the embodiment of the present invention, the current time period is divided into multiple sub-time periods, and the sending frequency of the target protocol message is dynamically adjusted according to the network conditions in the sub-time period; the sending process of the target protocol message is optimized by dynamically adjusting the sending frequency; when the network condition is good, the sending speed of the message can be accelerated by increasing the sending frequency, thereby improving the communication efficiency; and when the network condition is poor, the stability of the communication is ensured by reducing the sending frequency.

[0094] In a possible implementation manner of an embodiment of the present invention, network performance includes packet loss rate and delay; according to the network performance of the target network link, determining whether the target network link is in a network sub-healthy state includes: determining whether the packet loss rate exceeds a preset packet loss rate threshold; determining whether the delay exceeds a preset delay threshold; if the preset conditions are met, determining that the target network link is in a network sub-healthy state; otherwise, determining that the target network link is in a sub-healthy state; wherein the preset conditions include: the packet loss rate exceeds the preset packet loss rate threshold, or the delay exceeds the preset delay threshold.

[0095] In the embodiment of the present invention, two key network performance indicators, packet loss rate and latency, are comprehensively considered, and corresponding thresholds are set to determine whether the network is in a sub-healthy state, which simplifies the judgment logic and improves the detection speed and accuracy.

[0096] A possible implementation of the embodiment of the present invention, before determining whether the target network link is in a network sub-health state according to the network performance of the target network link, further includes:

[0097] Obtain historical threshold information for the previous period, the historical threshold information including: a preset packet loss rate historical threshold and a preset delay historical threshold;

[0098] Determine a first threshold adjustment value according to a difference between current network traffic and network traffic in a previous period;

[0099] Determine a second threshold adjustment value according to the time period to which the current moment belongs and the time period to which the previous time period belongs;

[0100] The threshold information is determined according to the first threshold adjustment value, the second threshold adjustment value and the historical threshold information, where the threshold information includes: a preset packet loss rate threshold and a preset delay threshold.

[0101] In an embodiment of the present invention, historical threshold information and network traffic of the previous time period are obtained; based on the difference in network traffic between the previous and next time periods, the change in network usage pattern is determined. If the current network traffic is higher than that of the previous time period, the threshold may need to be increased to avoid false alarms; if the current network traffic is lower than that of the previous time period, the threshold may need to be lowered to increase the sensitivity of detection. Based on the first corresponding relationship, a first threshold adjustment value corresponding to the difference is determined, wherein the first corresponding relationship is a corresponding relationship between multiple differences and multiple adjustment values.

[0102] Time factors may also affect performance. Multiple time periods are set. Network loads in different time periods are different. By considering the time period, the threshold can be adjusted more accurately to adapt to network conditions in different time periods. According to the time period and the second correspondence, the second threshold adjustment value corresponding to the time period is determined, where the second correspondence is a correspondence between multiple time periods and multiple adjustment values.

[0103] A new preset packet loss rate threshold and a preset delay threshold are determined according to the previously calculated first threshold adjustment value, the second threshold adjustment value and the acquired historical threshold information.

[0104] Specifically, in an achievable manner, the new packet loss rate threshold T1 can be calculated by the following formula:

[0105] Tl = Hl + α × Δf + β × Δt;

[0106] The new delay threshold Td can be calculated in a similar way:

[0107] Td = Hd + γ × Δf + δ × Δt;

[0108] Wherein, Hl: historical packet loss rate threshold; Hdy: historical delay threshold; Δf: first threshold adjustment value; Δt: second threshold adjustment value; Tl: new packet loss rate threshold; Td: new delay threshold; α, β, γ and δ are weight values, and the specific size can be customized by the user, α+β=1, γ+δ=1.

[0109] It should be noted that both Tl and Td are set to finite values, and when reaching their respective corresponding limits, they no longer change.

[0110] It can be seen that in the embodiment of the present invention, the preset packet loss rate and delay thresholds are dynamically adjusted according to factors such as historical data, current network traffic changes and time periods, and an adaptive adjustment mechanism is used to make the thresholds more in line with the actual situation of the current network environment, thereby avoiding false alarms or missed alarms caused by fixed thresholds.

[0111] Based on any of the above embodiments, see Figure 3 , Figure 3 A flowchart of a specific method provided by an embodiment of the present invention includes:

[0112] (1) The client triggers the sending of network sub-health detection messages to the server

[0113] (2) After the server detects the network sub-health message, it immediately returns the message to the client

[0114] (3) The client calculates whether there is a network sub-health problem of delay and packet loss based on the message reception situation. If a network sub-health problem is found, jump to (4); otherwise, jump to (10)

[0115] (4) The client sends a BDF detection message to the switch

[0116] (5) After receiving the message, the switch immediately returns the BDF detection message to the client.

[0117] (6) The client calculates whether there is a packet loss problem based on the message reception. If there is BDF packet loss, jump to (7); otherwise jump to (8)

[0118] (7) If there is a problem with the link from the client to the switch, jump to (9)

[0119] (8) The prompt may be a problem with the client itself or the server link. Jump to (9)

[0120] (9) Shut down the problematic network port and jump to (10)

[0121] (10) End.

[0122] In an embodiment of the present invention, the C / S architecture is first used to detect delay and packet loss according to the original network sub-health detection logic. When it is found that the delay and / or packet loss exceeds the threshold, the BFD protocol (SMP protocol) is immediately re-judged, that is, a two-way forwarding detection protocol message is created and sent to the outside to detect whether there is a problem from the node to the switch. If there is also packet loss in the two-way forwarding detection protocol message, the node system status is immediately re-judged, that is, whether there is a problem with the node resources (CPU, memory, network). According to the above logic, it can be determined whether the fault is in the Client node or in the link from the Client to the switch. Through the above logic, the specific problem point can be quickly located, the accuracy of network sub-health detection is improved, the probability of misjudging the packet loss exceeding the threshold is reduced, and the operation and maintenance efficiency can also be improved.

[0126] The re-judgment module 230 is used to send a target protocol message to the switch if the target network link is in a sub-healthy state, and the target protocol message is used to make the switch return a target protocol feedback message;

[0127] The second determination module 240 is used to determine the status of each device of the target network link according to the packet loss information of the target protocol feedback message and the node resource information of the electronic device.

[0128] In an embodiment of the present invention, the acquisition module 210 acquires the network performance of the target network link, and the first determination module 220 can accurately determine whether the target network link has entered a sub-healthy state based on the network performance data; when the sub-healthy state is detected, the re-judgment module 230 will quickly send the target protocol message to the switch, and the second determination module 240 uses the target protocol feedback message returned by the switch and the node resource information of the electronic device to comprehensively evaluate the specific status of each device on the target network link, which not only realizes real-time monitoring of the network status, but also can quickly determine the fault condition.

[0129] In one achievable manner, the target protocol message is a bidirectional forwarding detection protocol message or an icmp protocol message.

[0138] Divide the current period into multiple sub-periods;

[0139] Sending a target protocol message to the switch at a first frequency in a first sub-period;

[0140] If the sub-packet loss information of the first sub-period indicates that there is no packet loss, the target protocol message is sent to the switch at the second frequency in the next sub-period; the second frequency is greater than the first frequency; otherwise, the target protocol message is sent to the switch at the first frequency in the next sub-period; until the sending of the target protocol message in the current period is completed.

[0141] In one achievable approach, network performance includes packet loss rate and latency;

[0142] When determining whether the target network link is in a sub-healthy state according to the network performance of the target network link, the first determining module 220 is used to:

[0143] Determine whether the packet loss rate exceeds a preset packet loss rate threshold; determine whether the delay exceeds a preset delay threshold;

[0144] If the preset conditions are met, it is determined that the target network link is in a sub-healthy state; otherwise, it is determined that the target network link is in a sub-healthy state;

[0145] The preset conditions include: a packet loss rate exceeding a preset packet loss rate threshold, or a delay exceeding a preset delay threshold.

[0146] In an implementable manner, the first determining module 220 is further configured to:

[0147] Obtain historical threshold information for the previous period, the historical threshold information including: a preset packet loss rate historical threshold and a preset delay historical threshold;

[0148] Determine a first threshold adjustment value according to a difference between current network traffic and network traffic in a previous period;

[0149] Determine a second threshold adjustment value according to the time period to which the current moment belongs and the time period to which the previous time period belongs;

[0150] The threshold information is determined according to the first threshold adjustment value, the second threshold adjustment value and the historical threshold information, where the threshold information includes: a preset packet loss rate threshold and a preset delay threshold.
