[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The terms "first" and "second" in the specification and claims of this application are used to distinguish different objects, rather than to describe a specific order of objects. For example, a first edge service node and a second edge service node are used to distinguish different edge service nodes, rather than to describe a characteristic order of edge service nodes.

[0035] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0036] In addition, in the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present concepts in a specific way.

[0037] From the Ethernet bus topology in the 1970s to the star topology in the 1990s, and then to the mesh topology that is widely used today, network topology has undergone many important changes, and network topology has gradually changed from simple to complex. In the 21st century, Software Defined Network (SDN) as a new network architecture has achieved higher flexibility and programmability by separating the network control plane from the forwarding plane.

[0038] As network topology becomes increasingly complex, network topology disaster recovery, emergency response, migration, upgrade, verification and other scenarios also face huge challenges. In the current network environment, users are increasingly relying on the network for daily communication, leisure, remote office and other daily activities, and the network has gradually become an indispensable part of people's daily life. At the same time, with the rise of (IoT), hundreds of millions of device connections and an increasing number of mobile, desktop, car and other networked devices have been brought about, requiring new topological structures to effectively manage a large number of concurrent connections. This also faces huge challenges in the migration, upgrade and verification of network topology. Moreover, under the premise that the majority of users are currently very dependent on it, when upgrading and verifying the network topology, it cannot be operated directly in the existing network environment, and the current environment needs to be cloned for testing and verification and network upgrade. At the same time, in response to disaster recovery, emergency handling, and before the formal network upgrade, it is also necessary to back up the current network topology information to achieve the purpose of rapid recovery. Therefore, the stability of the network environment and the emergency recovery measures in the face of network failures are the key tasks of current network security.

[0039] In the related art, technicians input commands to set the configuration commands of the recovery equipment, thereby restoring the configuration of the network equipment and ensuring the stability of the network. However, with the complexity of network topology and the diversification of network equipment, manual recovery of the configuration of network equipment has the problems of complicated operation and high error rate. Therefore, how to improve the efficiency of network equipment configuration recovery is a technical problem that still needs to be solved.

[0040] Based on the above technical solution, in the embodiment of the present application, the network topology establishment device obtains the topology information of the network topology to be reconstructed. Since the topology information includes the connection relationship between the network nodes and the device information of the node devices corresponding to the network nodes, the network topology establishment device can construct the network structure of the target network topology with the same device type as the node devices corresponding to the same network node in the network topology to be reconstructed based on the connection relationship between the network nodes in the network topology to be reconstructed and the device type of the node devices in the network topology to be reconstructed. Considering that the topology information also includes the configuration file of the node device, the network topology establishment device can determine the configuration information of the node devices in the target network topology based on the configuration file of the node devices in the network topology to be reconstructed and the recovery configuration process information in the device information. Thus, the network topology establishment device can establish the target network topology according to the network structure of the target network topology and the configuration information of the node devices in the target network topology. Compared with the prior art, the present application does not need to manually configure the network device configuration, avoids the defects of high error rate and time-consuming and labor-intensive manual operation caused by manually configuring the network device configuration, and improves the configuration recovery efficiency of the network device.

[0041] For example, Figure 1 As shown, Figure 1 This is a schematic diagram of the architecture of a network topology establishment system provided in the present application. The network topology establishment system 10 includes: a data acquisition device 101 and a network topology establishment apparatus 102.

[0042] The data collection device 101 is to reconstruct topology information of the network topology.

[0043] The network topology establishment device 102 obtains the topology information of the network topology to be reconstructed through the data acquisition device 101; based on the connection relationship between the network nodes in the network topology to be reconstructed and the device type of the node devices in the network topology to be reconstructed, the network structure of the target network topology is constructed; the device type of the node devices corresponding to the same network nodes in the target network topology is the same as that in the network topology to be reconstructed. Based on the configuration files and the configuration recovery process information of the node devices in the network topology to be reconstructed, the configuration information of the node devices in the target network topology is determined. The target network topology is established according to the network structure of the target network topology and the configuration information of the node devices in the target network topology.

[0044] Optionally, the topology information includes the connection relationship between network nodes, the device information of the node device corresponding to the network node and the configuration file of the node device; the device information includes the device type and configuration recovery process information; the configuration recovery process information includes process information for restoring the target configuration of the node device.

[0045] Optionally, the physical device of the data collection device 101 is a terminal, and the physical device of the network topology establishment device 102 is a server.

[0046] Optionally, the above-mentioned terminal may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. The wireless terminal may communicate with one or more core networks via a radio access network (RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network, such as a mobile phone, a tablet computer, a laptop computer, a netbook, a personal digital assistant (PDA).

[0047] Optionally, the above-mentioned server can be a server in a server cluster (consisting of multiple servers), or a chip in the server, or a system on a chip in the server, or can be implemented by a virtual machine (VM) deployed on a physical machine, which is not limited in the embodiments of the present application.

[0048] The embodiment of the present application provides a network topology establishment device, which is used to execute the network topology establishment system provided by the embodiment of the present application. Figure 2 The structure diagram of a network topology establishment device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the network topology establishing device 200 includes at least one processor 201, a communication line 202, and at least one communication interface 204, and may also include a memory 203. The processor 201, the memory 203 and the communication interface 204 may be connected via the communication line 202.

[0049] The processor 201 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application, such as one or more digital signal processors (DSP), or one or more field programmable gate arrays (FPGA).

[0050] The communication link 202 may include a pathway for transmitting information between the above-mentioned components.

[0051] The communication interface 204 is used to communicate with other devices or communication networks, and can use any transceiver-like device, such as Ethernet, radio access network (RAN), WLAN, etc.

[0052] The memory 203 may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, an optical disc storage (including compressed optical discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to include or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to these.

[0053] In one possible design, the memory 203 can exist independently of the processor 201, that is, the memory 203 can be a memory outside the processor 201. In this case, the memory 203 can be connected to the processor 201 through the communication line 202, and is used to store execution instructions or application code, and the processor 201 controls the execution to implement the network topology establishment method provided in the following embodiment of the present application. In another possible design, the memory 203 can also be integrated with the processor 201, that is, the memory 203 can be the internal memory of the processor 201, for example, the memory 203 is a high-speed cache, which can be used to temporarily store some data and instruction information.

[0054] As an implementation method, the processor 201 may include one or more CPUs, such as Figure 2 As another possible implementation, the network topology establishment device 200 may include multiple processors, such as Figure 2 As another possible implementation, the network topology establishment apparatus 200 may further include an output device 205 and an input device 206.

[0055] Below, combined with the attached Figure 3 The network topology establishment method provided in the embodiment of the present application is described in detail. Figure 3 As shown, the network topology establishment method includes S301-S304.

[0056] S301. A network topology establishing device obtains topology information of a network topology to be rebuilt.

[0057] Among them, the topology information includes the connection relationship between network nodes, the device information of the node devices corresponding to the network nodes and the configuration files of the node devices; the device information includes the device type and the recovery configuration process information; the recovery configuration process information includes the process information of restoring the target configuration of the node device.

[0058] In a possible implementation, the network topology establishing device obtains topology information of the network topology to be rebuilt from the backup server.

[0059] Optionally, the topology information also includes at least one of the following: topology name, node name, device name, and management IP address of the device.

[0060] It needs to be explained that the topology name is used to identify the topology, the node name is used to identify the source of the data, and the device name is used to identify the device. Only when the device is configured with a management IP can its configuration file be automatically backed up over the network.

[0061] S302: The network topology establishing device constructs a network structure of a target network topology based on the connection relationship between network nodes in the network topology to be rebuilt and the device types of node devices in the network topology to be rebuilt.

[0062] The device types of the node devices corresponding to the same network nodes in the target network topology and the network topology to be rebuilt are the same.

[0063] Optionally, there is a one-to-one correspondence between network nodes and devices.

[0064] In one possible implementation, the network topology establishing device determines the device type of the node device in the network topology to be rebuilt, connects the node devices in the network topology to be rebuilt based on the connection relationship between the network nodes in the network topology to be rebuilt, and generates the network structure of the target network topology.

[0065] It can be understood that the network structure includes node devices and connection relationships between node devices.

[0066] S303: The network topology establishing device determines configuration information of the node devices in the target network topology based on the configuration files and the configuration recovery process information of the node devices in the network topology to be rebuilt.

[0067] In a possible implementation, the network topology establishing device runs the configuration files of the node devices in the network topology to be rebuilt by restoring the configuration process information to determine the configuration information of the node devices in the target network topology.

[0068] Optionally, the recovery configuration process information includes computer instructions.

[0069] S304: The network topology establishing device establishes the target network topology according to the network structure of the target network topology and the configuration information of the node devices in the target network topology.

[0070] In a possible implementation, the network topology establishing device configures the node devices in the network structure of the target network topology according to the configuration information of the node devices in the target network topology to establish the target network topology.

[0071] Optionally, the target network topology includes a physical topology or a virtual topology.

[0072] It should be explained that the physical topology physically connects devices with cables, representing the actual wiring and connection layout; the virtual topology is a geometric structure composed of elements such as faces, edges and vertices, which is used to describe the boundaries of the model in simulation analysis. It can ignore or simplify the details of the model as needed, making it easier to generate a mesh with better quality.

[0073] In a possible implementation, the network topology establishing device establishes a target network topology on an openstack cloud platform.

[0074] The above scheme brings at least the following beneficial effects: the network topology establishment device obtains the topology information of the network topology to be reconstructed. Since the topology information includes the connection relationship between the network nodes and the device information of the node devices corresponding to the network nodes, the network topology establishment device can construct the network structure of the target network topology with the same device type as the node devices corresponding to the same network node in the network topology to be reconstructed based on the connection relationship between the network nodes in the network topology to be reconstructed and the device type of the node devices in the network topology to be reconstructed. Considering that the topology information also includes the configuration file of the node device, the network topology establishment device can determine the configuration information of the node devices in the target network topology based on the configuration file of the node devices in the network topology to be reconstructed and the recovery configuration process information in the device information. Thus, the network topology establishment device can establish the target network topology according to the network structure of the target network topology and the configuration information of the node devices in the target network topology. Compared with the prior art, the present application does not need to manually configure the network device configuration, avoids the defects of high error rate and time-consuming and labor-intensive manual operation caused by manual configuration of the network device configuration, and improves the configuration recovery efficiency of the network device.

[0075] In one possible implementation, combining Figure 3 ,like Figure 4 As shown, before the network topology establishment device obtains the topology information of the network topology to be rebuilt in S301, the network topology establishment device backs up the configuration files of the node devices in the network topology to be rebuilt. The process of the network topology establishment device backing up the configuration files of the node devices in the network topology to be rebuilt can be specifically implemented through the following S401-S403.

[0076] S401. The network topology establishing device determines the operating status of the node devices in the network topology to be rebuilt based on the power status and the operating system operating status of the node devices in the network topology to be rebuilt.

[0077] In a possible implementation, the network topology establishment device determines the power state through the state of the power indicator light of the node device, and determines the operating system operating state by detecting the node device operating information. Then, the operating state of the node device in the network topology to be rebuilt is determined according to the power state and the operating system operating state of the node device in the network topology to be rebuilt.

[0078] Optionally, the node device operation information includes at least one of the following: CPU usage, memory occupancy, and disk input / output (I / O) information.

[0079] S402: The network topology establishing device determines whether access is allowed to a node device in the network topology to be rebuilt through a network detection tool.

[0080] Optionally, use the ping command to detect the network.

[0081] In a possible implementation, the network topology establishment device determines whether the management IP of the node device in the network topology to be rebuilt is reachable through a network detection tool. If the management IP of the node device in the network topology to be rebuilt is reachable, the network topology establishment device determines that the node device in the network topology to be rebuilt is allowed to be accessed; if the management IP of the node device in the network topology to be rebuilt is not reachable, the network topology establishment device determines that the node device in the network topology to be rebuilt is not allowed to be accessed.

[0082] It needs to be explained that the ping command is a commonly used network tool for testing the quality of a network connection with another computer. It works by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting to receive echo reply packets. The ping command can not only help you confirm whether the target host is reachable, but also provide network performance indicators such as Round-Trip Time (RTT).

[0083] S403: When the running state of the node device in the network topology to be rebuilt is the power-on state and the node device in the network topology to be rebuilt allows access, the network topology establishing device backs up the configuration files of the node device in the network topology to be rebuilt.

[0084] In a possible implementation, the network topology establishing device obtains topology information and configuration files of node devices in the network topology to be rebuilt, and backs up the topology information and configuration files of node devices to a backup database.

[0085] It should be explained that the network topology establishment device accesses each node device in the network topology to be rebuilt through the File Transfer Protocol (FTP) to download the configuration file of each node device.

[0086] Table 1. Network topology backup table

[0087]

[0088]

[0089] Exemplarily, as shown in Table 1, during the first backup in topology 1, the device of node 1 is manufactured by the first communications company, the device model is the first device model, the management IP is 192.168.1.10, and the configuration information is the configuration information of node 1; the device of node 2 is manufactured by the second communications company, the device model is the second device model, the management IP is 192.168.1.20, and the configuration information is the configuration information of node 2; the device of node 3 is manufactured by the third communications company, the device model is the third device model, the management IP is 192.168.1.30, and the configuration information is the configuration information of node 3; the device of node 4 is manufactured by the fourth communications company, the device model is the fourth device model, the management IP is 192.168.1.40, and the configuration information is the configuration information of node 4; the device of node 5 is manufactured by the fifth communications company, the device model is the fifth device model, the management IP is 192.168.1.50, and the configuration information is the configuration information of node 5.

[0090] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the network topology establishment device obtains the information of each node in the network topology and backs up each node in the network topology. In this way, when the user needs to establish the topology again, the main need is to quickly and accurately establish the network topology based on the backed-up information of each node, thereby improving the efficiency of establishing the network topology.

[0091] In one possible implementation, combining Figure 4 ,like Figure 5 As shown, in S402, the network topology establishing device determines whether access is allowed to a node device in the to-be-reconstructed network topology by using a network detection tool, which can be specifically implemented through the following S501-S502.

[0092] S501. In the case where a node device in the network topology to be rebuilt is configured with a management Internet Protocol IP, a network topology establishing apparatus runs a ping command based on the management IP of the node device in the network topology to be rebuilt.

[0093] In a possible implementation, the network topology establishment device obtains the management IP of the node device in the network topology to be rebuilt, and sends a data packet to the node device through the management IP of the node device and the ICMP protocol. In this way, after receiving the data packet, the node device sends an ICMP echo reply data packet to the ping command.

[0094] Optionally, the data packet is an ICMP echo request data packet.

[0095] S502: The network topology establishing device determines whether a node device in the network topology to be rebuilt is accessible based on the running result of the ping command.

[0096] In one possible implementation, when the network quality in the running result of the ping command is greater than or equal to the preset network quality, the network topology establishment device determines that the node device in the network topology to be rebuilt is accessible; when the network quality in the running result of the ping command is less than the preset network quality, the network topology establishment device determines that the node device in the network topology to be rebuilt is inaccessible.

[0097] It should be explained that after receiving the ICMP echo reply data packet, the ping command determines the data transmission information based on the ICMP echo request data packet and the ICMP echo reply data packet. The ping command determines the network quality based on the data transmission information.

[0098] Optionally, the data transmission information includes at least one of the following: data sending duration, data receiving duration, data loss information, data sending times, data packet size, and data packet format.

[0099] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the network topology establishment device runs a ping command based on the management IP of the node device in the network topology to be rebuilt. In this way, the network topology establishment device determines whether the node device in the network topology to be rebuilt is accessible based on the running result of the ping command, thereby ensuring the communication of the node device in the network topology to be rebuilt and improving the backup efficiency of the node data.

[0100] In one possible implementation, combining Figure 4 ,like Figure 6 As shown, after the network topology establishment device backs up the configuration files of the node devices in the network topology to be rebuilt in S403, the network topology establishment device updates the configuration recovery process table. The process of the network topology establishment device updating the configuration recovery process table can be specifically implemented through the following S601-S603.

[0101] S601: The network topology establishing device determines whether a node device in the network topology to be rebuilt is recorded in a configuration recovery process table.

[0102] The recovery process table includes at least one node device and recovery configuration process information corresponding to at least one node device.

[0103] In a possible implementation, the network topology establishment device queries from the configuration recovery process table whether there is a first node device with the same name as the node device in the network topology to be rebuilt based on the name of the node device in the network topology to be rebuilt. If there is, the network topology establishment device determines that the node device in the network topology to be rebuilt is recorded in the configuration recovery process table; if not, the network topology establishment device determines that the node device in the network topology to be rebuilt is not recorded in the configuration recovery process table.

[0104] S602: When the node device in the network topology to be rebuilt is not recorded in the configuration recovery process table, the network topology establishment device obtains initial recovery configuration process information of the node device in the network topology to be rebuilt.

[0105] In a possible implementation, the network topology establishing device obtains the initial recovery configuration process information of the node devices in the network topology to be rebuilt from the backup server.

[0106] S603: The network topology establishing device updates the configuration recovery process table based on the initial recovery configuration process information of the node devices in the network topology to be rebuilt.

[0107] In one possible implementation, the network topology establishing device verifies the accuracy of the initial recovery configuration of the node devices in the network topology to be rebuilt. If the initial recovery configuration of the node devices in the network topology to be rebuilt passes the accuracy verification, the initial recovery configuration process information of the node devices in the network topology to be rebuilt is stored in the configuration recovery process table.

[0108] Table 2. Configuration recovery process table

[0109]

[0110] For example, as shown in Table 2, in the configuration recovery process table, the recovery configuration step for the first device model of the first communication company is system-view configuration replace file config.cfg; the recovery configuration step for the second device model of the second communication company is system-view startup saved-configurationconfig.cfg; the recovery configuration step for the third device model of the third communication company is system-view loadconfiguration config.cfg; the recovery configuration step for the fourth device model of the fourth communication company is system-view load configuration config.cfg; and the recovery configuration step for the fifth device model of the fifth communication company is enable load configuration config.cfg.

[0111] The above scheme brings at least the following beneficial effects: in the embodiment of the present application, the network topology establishment device updates the configuration recovery process table in real time. In this way, when the user needs to build a network topology, the node device recovery configuration steps can be obtained from the configuration recovery process table based on the device manufacturer and device model of the node device, thereby improving the efficiency of establishing the network topology.

[0112] In one possible implementation, combining Figure 6 ,like Figure 7 As shown, in S603, the process in which the network topology establishing device updates the configuration recovery process table based on the initial recovery configuration process information of the node devices in the network topology to be rebuilt can be specifically implemented through the following S701-S703.

[0113] S701. A network topology establishing device obtains device usage information of node devices in a network topology to be rebuilt.

[0114] The device usage information includes instruction operation specifications of node devices in the network topology to be rebuilt.

[0115] In a possible implementation, the network topology establishing device obtains device usage information of the node devices in the network topology to be rebuilt from a network server of a manufacturer to which the node devices in the network topology to be rebuilt belong.

[0116] S702: The network topology establishing device verifies the reliability of the initial recovery configuration process information based on the usage information.

[0117] In a possible implementation, the network topology establishing device runs the initial recovery configuration process information in a preset server based on the device usage information, and verifies the reliability of the initial recovery configuration process information according to the running result.

[0118] S703: When the initial recovery configuration process information passes the reliability verification, the network topology establishing device determines the initial recovery configuration process information as the recovery configuration process information of the node device in the network topology to be rebuilt in the configuration recovery process table.

[0119] In a possible implementation, the network topology establishing device stores the initial recovery configuration process information and the node devices in a configuration recovery process table, and establishes a corresponding relationship between the initial recovery configuration process information and the node devices.

[0120] In another possible implementation, the network topology establishing device deletes the preset recovery configuration process information corresponding to the node device, stores the initial recovery configuration process information in the configuration recovery process table, and establishes a corresponding relationship between the initial recovery configuration process information and the node device.

[0121] For example, Figure 8As shown, during the process of backing up the network topology to be rebuilt, the network topology establishing device determines whether the network topology to be rebuilt is a physical topology. When the network topology to be rebuilt is not a physical topology, the network topology establishing device obtains and saves the basic information of the network topology from the virtualization platform; when the network topology to be rebuilt is a physical topology, the network topology establishing device records the basic information of each node in the network topology in Table 1. The network topology establishing device verifies the network topology, downloads and saves the configuration files of each order through the FTP tool, and checks whether the device model of the newly added node is recorded in the configuration recovery process table 2. When it is checked that the device model of the newly added node is recorded in Table 2, the backup process is terminated. When it is checked that the device model of the newly added node is not recorded in Table 2, the model configuration recovery process of the newly added node is collected and verified, and the newly added configuration recovery process is updated to Table 2.

[0122] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the network topology establishment device uses information to verify the reliability of the initial recovery configuration process information, so that the initial recovery configuration process information can be guaranteed to be used normally.
