For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic view of an application environment of a network state detection method according to an embodiment of the disclosure. The execution basis in this embodiment is an SDWAN networking, as shown in fig. 1. In this embodiment, the architecture design of the SDWAN networking is implemented using the BGP/FOU protocol. The SDWAN networking comprises at least a control center and a plurality of gateways, and the SDWAN networking exists in the form of a control center node and gateway nodes. The control center node issues configuration to the network node and configures communication connection of each gateway node in the whole network. Under the configuration of the control center node, tunnels are established between each gateway node of the same SDWAN networking and other gateway nodes for communication, and data transmission is realized among the gateways according to transmission requirements. According to the illustration of fig. 1, a corresponding tunnel is established between two gateway nodes identified with double-headed solid arrows, and data can be directly transferred between the two gateways. If the gateway 1 and the gateways 2, 3, 4 are respectively identified by double-headed solid arrows, it means that the gateway 1 can directly transmit data with the gateways 2, 3, 4.
In this embodiment, the gateway corresponding to each gateway node is disposed in the same machine room, and each gateway is responsible for forwarding all data output or input by the respective machine room. Each gateway may be located in a geographical area, such as a city, and is responsible for data interaction and data processing in the corresponding geographical area. In this embodiment, the SDWAN networking may be used to build business data centers, the internet, or cloud services for an enterprise network or enterprise, such as configuring and processing live data generated by a live application throughout a place. And the gateway corresponding to each gateway node can be directly connected with the clients in the corresponding geographic areas and establish communication connection with the clients in other geographic areas. The same gateway forms a local area network with clients in the corresponding geographic area to which it is connected, while the gateway forms a wide area network with other gateways and corresponding clients of the SDWAN networking.
Referring to fig. 2, fig. 2 is a flow chart of a network state detection method according to an embodiment of the disclosure. According to fig. 2, the network state detection method provided in the embodiment of the present application includes the following steps:
s210, two target gateway nodes are selected from the SDWAN networking.
In the SDWAN networking shown in fig. 1, the control center node may select any two gateway nodes corresponding to the two gateways as the target gateway node. Wherein, the tunnel is established or not directly established between the two target gateway nodes.
The two target gateway nodes can acquire two gateway nodes or two gateway nodes in a set of gateway nodes of a certain block according to the checking requirement of the network state; or the requirement of comprehensive inspection can be met, and all network nodes at a certain moment in the SDWAN networking are arranged and combined to obtain all the gateway nodes combined pairwise.
S220, obtaining the IP routing path at the appointed moment according to the network routing data corresponding to the target gateway node.
The SDWAN networking provided in this embodiment may change due to the increase or decrease of gateway nodes, the change of network states between a certain gateway node or paths of two gateway nodes in the networking, the change of configuration of a control center node, and the like. Therefore, even two identical target gateway nodes, the IP routing paths corresponding to different times are not necessarily identical.
When the selected target gateway node in step S210 establishes a tunnel with other gateway nodes to perform communication, corresponding network routing data is formed, where the network routing data includes IP address information of itself and other gateway nodes that establish tunnels. And obtaining a data transmission path between gateway nodes according to the network routing data. Combining paths between at least two gateway nodes can result in an IP routing path between the two gateway nodes at the specified time. The IP routing path may be an IP routing path formed by directly connecting the two target gateway nodes provided above, or may be an IP routing path formed by indirectly connecting communication connections of a plurality of other gateway nodes.
S230, acquiring network health data of the IP routing path, and associating the network health data on the IP routing path to show the network state between the target gateway nodes.
The control center is connected with at least two gateway nodes through the IP routing path obtained in step S220. The network routing data of each gateway node comprises network quality information of a tunnel comprising the gateway node, and the IP routing paths obtained by the two target gateway nodes comprise corresponding network health data. The network health data includes network delays and packet loss rates for tunnels established between all gateway nodes in the IP routing path. The network delay and packet loss rate determinants include factors such as the network quality of the gateway node involved, and the network status of the tunnel in the IP routing path.
Therefore, in the IP routing path, the gateway nodes contain corresponding network health data. In this step, the network health data is associated with the corresponding IP routing path. The association method may be to mark the corresponding network health data on the corresponding IP routing path, or display the IP routing path in other manners such as symbols or wires capable of reflecting the network health data, so as to obtain the network health data between the target gateway nodes, and obtain the network status between the target gateway nodes.
According to the network state detection method provided by the embodiment of the application, network health data are associated to the IP routing paths obtained by calculation of the two target gateway nodes in the SDWAN networking, so that the network states of the two target gateway nodes can be clearly displayed, and the network connection conditions of the two gateway nodes in communication connection of the SDWAN networking can be conveniently monitored and checked; meanwhile, the communication fault of the SDWAN networking can be rapidly positioned so as to remove the fault in time and repair the network in time.
As shown in fig. 1, the architecture of the SDWAN networking provided above may further include a log collector and a database connected to the log collector.
The log collector is in communication connection with each gateway node of the SDWAN networking and is used for acquiring network health data and network routing data collected and reported by each network.
Before the step S210, the network state detection method provided in this embodiment further includes: acquiring network health data and network routing data through a log collector; and the network health data and the network routing data are collected by all the gateways and are reported to the log collector at regular time for cleaning and storing in a database.
The gateway corresponding to each network node generates corresponding network routing data while in communication connection. And the network health data corresponding to the IP routing path can be obtained from the network nodes in the network health data.
In order to meet the real-time network state checking requirement, the control center acquires network routing data acquired and regularly reported by each network and network health data of an IP routing path where the network routing data are located through a log acquisition device. The log collector is used for cleaning the data and storing the data in a database.
In this embodiment, the network routing data exists in the form of routing messages, and the network health data exists in the form of health messages. After the log collector acquires the routing message and the health message, the routing message and the health message are analyzed to obtain network health data of the corresponding IP routing path at the appointed moment and network routing data of the corresponding gateway node, and the network health data and the network routing data of the corresponding gateway node are stored in a database for a long time at the appointed moment. So that the change of the network state can be detected according to the historical data of the SDWAN networking later, and the network fault can be conveniently checked.
For the above step S220, it can further include: and obtaining IP routing paths of the two target gateway nodes by using an IP routing algorithm according to the network routing data reported by the two target gateway nodes.
In this embodiment, data transmission can be performed directly between two selected target gateway nodes, and data transmission can be performed through associated nodes other than the two target gateway nodes. For example, the gateway node shown in fig. 1 is taken as a gateway 1 and a gateway 4 in the illustration as two selected target network nodes, and data can be directly transmitted between the gateway 1 and the gateway 4, or can be sequentially transmitted from a path of the gateway 1-gateway 2-gateway 3-gateway 4. That is, between two target gateway nodes, multiple IP routing paths can be formed. But the gateway and network states at a given moment change such that different IP routing paths have different transmission costs. The transmission cost does not necessarily depend on the number of gateway nodes comprised by the IP routing path. That is, the transmission cost of the IP routing path that does not contain the smallest number of target gateway nodes is the smallest.
In this embodiment, the next gateway node for data transmission is obtained by using the IP routing algorithm according to the network routing data reported by each target gateway node and establishing a tunnel with other gateway nodes and the IP routing path with the lowest communication cost. According to the IP routing algorithm, the IP routing path with the lowest communication cost of the current gateway node can be found in sequence, the next gateway node for data transmission is obtained continuously until the found next gateway node is another target network node, and therefore the IP routing paths of the two target gateway nodes are obtained at the appointed moment.
In the process of transmitting data by the two target gateway nodes in this embodiment, there is a sequence of data acquisition, so for step S210, it may further include: and designating an initial gateway node and a destination network node for data transmission in the SDWAN networking at the network node.
Referring to fig. 3, fig. 3 is a display interface of a gateway node provided in an embodiment of the disclosure. Square point 1 and square point 2 shown in fig. 3 are the originating gateway node and the destination gateway node, respectively, in this embodiment. The IP address of the originating gateway node is 10.13.13.13, and the IP address of the destination gateway node is 10.10.10.10. Before transmitting the data, forming the data into a data packet, and forming the corresponding IP address information of the initial gateway node and the destination gateway node into data packet information, such as: src 10.13.13.13, target 10.10.10.10. And transmitting the data packet carrying the data packet information so that the data packet can be transmitted to a corresponding destination gateway node according to the data packet information.
And obtaining the next gateway node of the current gateway node of the data packet by using an IP routing algorithm. As shown in fig. 3, if the current gateway node is a square node 1, a routing table of the gateway node of the square node 1 is obtained, and the two obtained data records are respectively: mask 10.10.10.Xxx, dest 10.123.123.32 and mask 10.10.11.255, dest 10.123.123.31. According to the IP address information of the destination network node, the matching degree of the two data records is higher, wherein the mask is 10.10.10.255, the dest is 10.123.123.32, the gateway node which is the next gateway node of the square node 1 is the gateway node of the IP address information dest is 10.123.123.32 according to the data records, and the data packet is forwarded to the gateway node with the IP address information of 10.123.123.32. In fig. 3, the gateway node whose IP address information is 10.123.123.32 is set as the round node 1. Meanwhile, the information forwarded by the current route is stored in the routing table of the gateway node of the square node 1.
During the transmission of the data packet, no matter which gateway node is forwarded to, the data packet information is unchanged, namely, src is 10.13.13.13, target is 10.10.10.10, so as to be forwarded to the destination gateway node.
After the first forwarding of the data packet is completed, the round node 1 is the current gateway node, and two data records obtained from the routing table are respectively: mask 10.10.10.Xxx, dest 10.123.123.60 and mask 10.10.11.Xxx, dest 10.123.123.61. Similarly, according to the IP address information 10.10.10.10 of the destination gateway node of the packet, the IP address information of the next gateway node of the round node 1 is 10.123.123.60, and in fig. 3, the gateway node is set as the round node 2. Meanwhile, the information of the second route forwarding is stored in the routing table of the gateway node of the round node 1.
After the second forwarding of the data packet is completed, the round node 2 is the current gateway node, and two data records obtained from the routing table are respectively: mask 10.10.10.255, dest 10.10.10.10 and mask 10.10.11.255, dest 10.10.10.11. According to the same way, the IP address information of the next gateway node of the round node 2 is 10.10.10.10, namely the next gateway node of the round node 2 is obtained as the target gateway node, and the data packet is transmitted to the target gateway node from the network node of the round node 2 while the information of the route forwarding is stored in the routing table of the gateway node of the round node 2. In fig. 3, the destination gateway node is set as square node 2.
And obtaining the IP routing path of the data packet from the initial gateway node to the target gateway node according to the transmission track comprising the gateway node.
On the basis of the embodiment of obtaining the IP routing path, the step of obtaining the network health data of the IP routing path in the step S230 may specifically include: and acquiring network health data of the IP routing paths of every two adjacent gateway nodes in the IP routing paths.
Referring to fig. 4, fig. 4 is a specific flowchart illustrating step S230 in the embodiment disclosed in the present application.
On this basis, step S230 may further include:
s231, taking network delay time and/or packet loss rate as preset marking conditions of the network state;
s232, obtaining network delay time and/or packet loss rate of the two adjacent gateway nodes according to the network health data of each two adjacent gateway nodes;
s233, according to the preset marking conditions, marking and displaying the network state between every two adjacent gateway nodes.
In steps 231-233, the control center presets a marking condition for the network state with one or more parameters of the network health data, so as to mark the network state at a specified time according to the detected result.
The data packet is transmitted between two target gateway nodes, and is transmitted between every two adjacent gateway nodes in the determined IP routing path according to the sequence, so that the network health data of the IP routing path between every two adjacent gateway nodes can be respectively obtained when the transmission condition of the whole IP routing path between the two target gateway nodes is obtained. In this embodiment, the network delay time and/or the packet loss rate of the IP routing path between every two adjacent gateway nodes may be obtained.
And corresponding to the packet loss rates of different degrees, marking by connecting lines with different colors or different thicknesses. Each connecting line is connected according to two adjacent gateway nodes of the determined IP routing path, and the two adjacent gateway nodes are connected by corresponding color connecting lines according to the packet loss rate of the corresponding two adjacent gateway nodes for transmitting the data packets.
As shown in fig. 3, the packet loss rates for different levels of packet loss rate are marked with links of different thicknesses. If the packet loss rate between the square node 1 and the round node 1 is 3%, the preset range of [0,5% ] of the packet loss rate is satisfied, and the identification is performed by the finest connecting line. The packet loss rate between the round node 2 and the square node 1 is 35%, the preset range of the packet loss rate [30%,100% ] is satisfied, and the route diagram of the IP routing path is obtained by marking with the coarsest connecting line.
And obtaining the loss condition of the corresponding IP routing path through the marks of the two adjacent gateway nodes on the IP routing path. According to the above embodiment, if the IP routing path is composed of a plurality of gateway nodes, it is possible to detect a loss situation between different gateway nodes. If the different transmission nodes positioned in the same gateway on the IP route path are obtained according to the IP address information, the transmission nodes are connected with each other. The corresponding transmission nodes can be connected through the connection lines in the preset form, and the network states of different parts of the wide area network and the local area network in the IP routing path can be easily confirmed.
In this embodiment, corresponding transmission times are preset for two adjacent transmission nodes (including a network node) in the IP routing path, and corresponding network delay times are obtained according to the IP address information of the corresponding transmission nodes. The network delay time of the IP routing path formed by two adjacent transmission nodes comprises the network delay time of the IP routing path positioned before the network delay time.
On the basis of the path diagram of the IP routing path, the network delay condition between the transmission nodes of the IP routing path can be shown, so as to facilitate the network state of the data transmission process.
The network state detection method provided by the application can also be used for positioning the fault condition of the network.
By detecting, when a fault occurs in two specific gateway nodes, and possibly or has influence on transmission, the two gateway nodes are taken as target gateway nodes, and the network state between the target gateway nodes is detected so as to locate the fault of the IP routing path.
As shown in fig. 1, the connection to the SDWAN networking in the figure further includes a log analyzer. The log analyzer establishes signal connection with the database, obtains information of different transmission nodes in the SDWAN networking acquired by the log acquirer through the database, and analyzes corresponding network states. In this embodiment, the fault information collected from the SDWAN networking may be used as a trigger condition, and the log analyzer is triggered and invoked to perform fault and monitoring, specifically, two gateway nodes with faults are determined through network health data and network routing data of all gateway nodes stored in a database, and the two gateway nodes are used as two target gateway nodes at corresponding moments, and the fault network state of the target gateway node is displayed in an alarm identification manner.
Then, according to the network state detection method provided above, network state detection is performed on the two target gateway nodes to obtain a path diagram showing the network state of the IP routing path, so that the fault part and the fault cause in the IP routing path between the two target gateway nodes can be easily located. In this embodiment, for two target gateway nodes with faults, a path diagram alarm identification mode of an IP routing path may be displayed; or if the detected network health data of the two adjacent gateway nodes exceeds the preset range, displaying the corresponding IP routing path on the path diagram of the IP routing path in an alarm identification mode.
And collecting the network health data and the network routing data generated by all gateway nodes through a log collector, and storing the network health data and the network routing data into a database. Moreover, the network health data and the network routing data carry time stamps corresponding to the generation time of each data.
When a network state detection request of a gateway node at a specific moment is received, a timestamp of corresponding network health data and network routing data is obtained from a database, the corresponding network health data and the network routing data are obtained, and the network health data and the network routing data are associated to an IP routing path between corresponding network nodes. The IP routing path may be a tunnel between two adjacent gateway nodes of the IP routing path mentioned in the above embodiments. If the IP routing path comprises more than two gateway nodes, decomposing the IP routing path into a plurality of tunnels between two adjacent gateway nodes, obtaining corresponding network health data and network routing data for each tunnel, and associating the network health data and the network routing data on the corresponding tunnels so as to show the network state of the corresponding gateway nodes in the SDWAN networking at the corresponding moment.
According to the detection steps, the method can be used for replaying and rewinding network states of each gateway node at different moments so as to further perform fault location on the SDWAN networking, and the aim of monitoring is achieved according to network state changes at different moments.
