Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for detecting a network connectivity status according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
The network topology structure may be a network node connection structure established for a terminal to access a network, and may generally be composed of multiple layers of network nodes, where each layer of network nodes may be respectively configured to provide different services or functions, for example, a network topology structure in which the terminal accesses an external network, i.e., a wide area network, may have 4 layers, a first layer is a domain name resolution layer configured to provide DNS domain name resolution services, a second layer is a load layer configured to provide services such as load balancing, signature verification, acceleration, and the like, a third layer is a front-end processor layer configured to limit current and speed, provide functions such as a blacklist, a Distributed Denial of Service (DDOS for short), or a crawler, and a fourth layer is an application layer configured to provide a real application Service. It should be noted that the network topology is not limited to the 4-layer network topology, and may be a multilayer network topology arbitrarily set up according to actual needs.
The application layer may be a layer of the network topology that provides real application access services, typically the highest layer of the network topology.
The service interface information may be various interface information provided for the user to access the network in the application layer, such as a website access interface, access entries on a webpage, a video playing entry, and the like.
In this embodiment, the collecting of the service interface information of the application layer of the network topology may be scanning available interface information provided for a user to access a network in the application layer.
The first service layer and the second service layer may be two other layers in the network topology structure, except for the application layer, where there is a node connection relationship, and may be located before the application layer, that is, when a terminal accesses a network, the terminal needs to go through the first service layer and the second service layer before entering the application layer, and the first service layer and the second service layer are adjacent in the network topology structure.
The first service layer and the second service layer may each include one or more nodes, each node may be a network-side device or a network cluster, and when at least one of the first service layer and the second service layer includes a plurality of nodes, the first service layer and the second service layer may have a plurality of node connection relationships, for example, the first service layer includes 1 node, the second service layer includes 3 nodes, and the 1 node of the first service layer and the 3 nodes of the second service layer may respectively have a connection relationship; or, the first service layer includes 2 nodes, the second service layer includes 3 nodes, and each node of the first service layer may have a connection relationship with one or more nodes of the second service layer, respectively.
The collecting of the node connection information between the first service layer and the second service layer of the network topology may be to collect and integrate connection relationships between nodes between the first service layer and the second service layer in the network topology, so as to obtain which node in the first service layer has a connection relationship with the node in the second service layer.
For example, as shown in fig. 2, the connection relationship between 1 node of the domain name resolution layer and 4 nodes of the load layer may be collected, and the connection relationship between 4 nodes of the load layer and 3 nodes of the front-end processor layer may also be collected.
Optionally, as shown in fig. 2, the network topology includes a domain name resolution layer, a load layer, and a front-end processor layer;
the step 102 comprises:
and acquiring domain name address information from the node of the domain name resolution layer to each node of the load layer, and acquiring server address information from each node of the load layer to each node of the front-end processor layer.
In this embodiment, as shown in fig. 2, the network topology may include 4 layers, namely, a domain name resolution layer, a load layer, a front-end processor layer, and an application layer, when a user accesses a network through a terminal, the user needs to sequentially perform domain name resolution through the domain name resolution layer, then enter the load layer, share a current network access task among a plurality of operation units for execution, and then enter the front-end processor layer to ensure the security of the current network access task, and finally enter the application layer to provide a real application service for the user terminal.
As shown in fig. 2, each of the load layer, the front-end processor layer, and the application layer may include a plurality of nodes, each node of each layer may be connected to a different node of an adjacent layer to form a different access link, as shown in fig. 2, the node 1 of the domain name resolution layer may be connected to the nodes 2 and 3 of the load layer, the nodes 2 and 3 of the load layer may be connected to the node 4 of the front-end processor layer, and the node 4 of the front-end processor layer may be connected to the node 5 of the application layer, so that the nodes 1, 2, 4, and 5 and the nodes 1, 3, 4, and 5 form an access link, respectively.
When the node 2 of the load layer fails, but the alarm is not triggered because the proportion of the number of times of the failure is smaller or the failure does not reach a specific threshold value, if a traffic inlet depending on an application just needs to pass through the node 2, a network access request sent by the terminal cannot reach the front-end processor layer and the application layer, so that the network access failure of the user terminal cannot be caused because the network access request is not sensed by the application server.
In order to avoid the above situation, in this embodiment, node connection information between the domain name resolution layer and the load layer and node connection information between the load layer and the front-end processor layer may be collected, specifically, domain name address information from a node of the domain name resolution layer to each node of the load layer may be collected, for example, domain name address information (such as virtual IP address information) of a node of the load layer connected to a node 1 of the domain name resolution layer is collected, and it may be determined which nodes of the load layer and the node 1 of the domain name resolution layer have a connection relationship through the domain name address information, where each node of the load layer is allocated with a unique virtual IP address; and collecting server address information from each node of the load layer to each node of the front-end processor layer, for example, collecting server address information (such as Real Server (RS) address information) of a node of the front-end processor layer connected to the node 2 of the load layer, and determining which nodes of the load layer and the front-end processor layer have a connection relationship through the server address information, wherein each node of the front-end processor layer is allocated with a unique RS address.
Therefore, based on the collected domain name address information from the node of the domain name resolution layer to each node of the load layer and the collected server address information from each node of the load layer to each node of the front-end processor layer, the node communication state between the domain name resolution layer and the load layer and the node communication state between the load layer and the front-end processor layer are detected, so that when any node of the load layer and the front-end processor layer fails, the method in the embodiment can ensure that the node failure is detected in time, and is convenient for taking corresponding repair measures in time to avoid the condition of access failure when a user terminal accesses a network.
It should be noted that, in practical application, it may be configured to collect not only the node connection relationships between the domain name resolution layer and the load layer, and between the load layer and the front-end processor layer, but also the node connection relationships between any adjacent layers in the network topology structure by convention according to practical needs.
And 103, detecting the node connection state between the first service layer and the second service layer according to the service interface information and the node connection information.
Then, a node connectivity state between the first service layer and the second service layer may be detected according to the service interface information and the node connection information, specifically, a corresponding access link may be determined based on a certain service interface in the service interface information, and then a connectivity state between nodes included in the link is detected, specifically, each node may be sequentially accessed to see whether each node can normally operate.
For example, as shown in fig. 2, if it is determined that an access link of a certain service interface is, in turn, a node 1 of a domain name resolution layer, a node 2 of a load layer, a node 4 of a front-end processor layer, and a node 5 of an application layer, the node 1, the node 2, the node 4, and the node 5 may be sequentially accessed, if each node is normally accessed, it may be determined that a connection state of each node in the access link is good, and if a certain node has a fault and cannot be accessed, it may be determined that a connection state with the node is abnormal.
Optionally, the step 103 includes:
determining a first node of the first service layer and a second node in the second service layer based on the service interface information and the node connection information, wherein the second node has a connection relation with the first node;
and accessing the second node from the first node, and determining that a communication fault exists between the first node and the second node under the condition of failed access.
In this embodiment, two nodes having a connection relationship in the first service layer and the second service layer, that is, a first node of the first service layer and a second node of the second service layer, may be determined based on the service interface information and the node connection information, and the first node and the second node may be nodes in an access link corresponding to a certain service interface in the service interface information.
And then, the second node can be accessed from the first node to determine whether the access is successful or not, if the access is successful, the connection condition between the first node and the second node is determined to be good, the first node and the second node can work normally, and if the access is failed, the connection fault between the first node and the second node is determined to exist, and the abnormal fault exists in the second node.
For example, as shown in fig. 2, when accessing the node 2 of the load layer from the node 1 of the domain name resolution layer, if the access fails, it may be determined that the connection status between the node 1 and the node 2 is abnormal, the node 2 has a failure, and the node access address of the load layer needs to be replaced.
Therefore, the service layer with the communication fault and the corresponding nodes can be quickly and accurately determined by accessing each layer of nodes in the network topology structure in advance, the nodes with the fault can be maintained in time, specifically, the fault nodes can be manually repaired or replaced by maintainers, and the system can autonomously complete the fault repairing according to a preset fault repairing scheme.
Optionally, the accessing the second node from the first node, and in case of a failure in access, after determining that there is a connectivity fault between the first node and the second node, the method further includes:
and adjusting a third node which has a connection relation with the first node in the second service layer into an access entry node of the first node.
In this embodiment, after it is determined that a connectivity fault exists between the first node and the second node, a corresponding measure may be taken in time to repair the connectivity fault, specifically, an access entry node serving as a first node in the first service layer in the second service layer may be replaced, so as to ensure that a corresponding service interface can be normally accessed by enabling the first node to connect to another node in the second service layer, and more specifically, a third node in the second service layer, which has a connection relationship with the first node, may be determined from the node connection information, and adjusted to be the access entry node of the first node, so as to ensure that a user can normally access the corresponding service interface.
For example, as shown in fig. 2, when it is determined that the node 2 of the load layer has a fault, the node 3 of the load layer may be adjusted to serve as an access entry node of the node 1 of the domain name resolution layer, so as to ensure that the terminal can perform normal network access by sequentially accessing the node 1, the node 3, and the nodes 4 to 5.
Optionally, after step 103, the method further includes at least one of:
under the condition that the first service layer is a domain name resolution layer and the second service layer is a load layer, if the node communication fault between the first service layer and the second service layer is detected, modifying a node access address of the load layer;
and if the node communication fault between the first service layer and the second service layer is detected to occur under the condition that the first service layer is a load layer and the second service layer is a front-end processor layer, adjusting the server address of the front-end processor layer.
In this embodiment, when the first service layer is a domain name resolution layer and the second service layer is a load layer, if it is determined that a node connectivity fault exists between the domain name resolution layer and the load layer by detecting a node connectivity state between the domain name resolution layer and the load layer, a node access address of the load layer may be modified, so as to implement that another node in the load layer is used as an access entry node of a node in the domain name resolution layer, which has a connection relationship with the fault node in the load layer.
For example, as shown in fig. 2, in the case that there is a failure in the node 2 of the load layer, the access address of the node in the load layer, which has a connection relationship with the node 1 of the domain name resolution layer, may be modified, such as modifying the virtual IP address of the access node 2 to the backup virtual IP address of the node 2 or to the virtual IP address of the node 3.
When the first service layer is a load layer and the second service layer is a front-end processor layer, if it is determined that a node connectivity fault exists between the load layer and the front-end processor layer by detecting a node connectivity state between the load layer and the front-end processor layer, a server address, such as an RS address, of the front-end processor layer may be modified to process a network access task of a corresponding service interface through other server devices in the front-end processor layer, that is, to dynamically adjust an RS forwarding list of the front-end processor layer.
It should be noted that, while modifying the node access address of the load layer or adjusting the server address of the front-end processor layer, an alarm prompt signal may also be output to the management device of the corresponding layer, so as to notify the technical maintenance staff of the layer of the node failure message of the layer.
Optionally, the step 101 includes:
calling a service interface acquisition module to acquire service interface information of an application layer of a network topology structure;
sending the service interface information to an entrance detection module;
the step 102 comprises:
calling an entrance detection module to acquire node connection information between a first service layer and a second service layer of the network topology structure;
the step 103 comprises:
and the entrance detection module detects the node communication state between the first service layer and the second service layer according to the service interface information and the node connection information.
In practical application, in order to facilitate the node connectivity state detection function of the present solution to be realized by means of program calling, the present solution may be realized by developing an entry detection module for acquiring entry information of a node and detecting a node connectivity state and a service interface acquisition module for acquiring service interface information.
Specifically, as shown in fig. 2, the portal detection module may operate at a portal layer of the network topology, for example, the first service layer and the second service layer of the network topology, and the service interface acquisition module may operate at an application layer of the network topology, so that the service interface acquisition module may be called to acquire service interface information of the application layer and send the acquired service interface information to the portal detection module; the node connection information between the first service layer and the second service layer can be collected by calling an entrance detection module; the entrance detection module can detect the node connection state between the first service layer and the second service layer according to the received service interface information and the collected node connection information; as shown in fig. 2, the first service layer and the second service layer may be the domain name resolution layer and the load layer, respectively.
Thus, in the embodiment, the back-end service does not depend on the troubleshooting and positioning of an upper-layer team through the dynamic monitoring of the network topology structure from bottom to top, so that the problem can be found more quickly and the server can be switched to a normal server, the access success rate of each application service can be improved, and the business service quality of an enterprise can be ensured.
In this embodiment of the present invention, the mobile terminal may be any device having a storage medium, for example: terminal devices such as a Computer (Computer), a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (Personal Digital Assistant, abbreviated as PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device).
In the network connectivity state detection method in this embodiment, the service interface information of the application layer of the network topology structure is collected, and the node connection information between the first service layer and the second service layer of the network topology structure is collected, so that the node connectivity state between the first service layer and the second service layer can be detected according to the service interface information and the node connection information. Therefore, the communication faults among the nodes of each layer of the network topology structure can be detected in time, and the connection condition of the corresponding link can be adjusted quickly so as to avoid the failure of the terminal in accessing the network.
