[0043] The following explanations of the terms used in the embodiments of this disclosure are provided to facilitate the reader's understanding.

[0044] 1. Virtual Extended Local Area Network

[0045] Virtual Extensible Local Area Network (VXLAN) is a network virtualization technology defined by the Internet Engineering Task Force (IETF). It aims to address the scalability and isolation issues encountered by traditional VLANs in large-scale cloud computing and virtualization environments. VXLAN creates virtual networks over existing IP networks, encapsulating traffic and extending it to a Layer 3 gateway to achieve cross-regional Layer 2 interconnection. As an advanced network virtualization technology, VXLAN has been widely adopted in large data centers, cloud computing environments, and virtualized data centers due to its high scalability, flexibility, and multi-tenancy support. With continuous technological development, VXLAN is expected to become one of the mainstream network virtualization technologies.

[0046] 2. Network Topology

[0047] Network topology refers to the physical layout of various devices interconnected by transmission media, that is, the way and form of interconnection between nodes, which determines the data transmission route and efficiency in the network.

[0048] Currently, in network labs where network topology is built based on user requests, changes in user network topology requirements necessitate backing up network device configurations, dismantling existing fiber optic cables and network cables, and rewiring according to the new topology. However, due to the complexity of network topology cabling, redeploying physical cabling can easily lead to fiber optic loss, thus increasing the cost of network topology construction in network labs.

[0049] To address the aforementioned technical problems, this disclosure provides a network topology construction method, apparatus, and storage medium. This addresses the issues of complex network topology lines, fiber optic loss due to physical line redeployment, and high costs associated with network topology construction in network laboratories. The method includes: first, receiving a network topology construction request from a first terminal; determining the network devices used to construct the network topology based on the network topology structure in the request; then, identifying multiple VXLAN switches physically connected to the network devices and instructing them to construct VXLAN tunnels; and finally, connecting the network devices through these VXLAN tunnels to construct the network topology. This allows for network topology construction without dismantling physical lines when user network topology requirements change. Instead, existing VXLAN tunnels are disconnected, and new VXLAN tunnels are constructed based on the user's new requirements. This avoids fiber optic loss and reduces construction costs, thus solving the problems of complex network topology lines, fiber optic loss due to physical line redeployment, and high costs associated with network topology construction in network laboratories.

[0050] In one possible implementation, the above-described network topology construction method can be applied to the network topology construction system 100. The following, in conjunction with... Figure 1 This application provides a detailed description of a network topology construction system 100 according to an embodiment. For example... Figure 1 As shown, Figure 1 A network topology building system 100 is provided for embodiments of this disclosure. The system includes: a terminal 101 and a network topology building device 102.

[0051] The terminal 101 is used to send a network topology building request to the network topology building device 102. The network topology building request includes: a network topology structure; the network topology structure is used to determine the network devices used to build the network topology.

[0052] The network topology building device 102 is used to receive a network topology building request from the terminal 101, determine multiple network virtualization VXLAN switches based on the network topology structure; the multiple VXLAN switches are connected to different network devices based on physical lines; send first indication information to the multiple VXLAN switches; the first indication information is used to build a VXLAN tunnel between the multiple VXLAN switches; the VXLAN tunnel is used to connect network devices through the multiple VXLAN switches to build the network topology.

[0053] In one possible implementation, the hardware structure of the network topology building device includes: Figure 2 The components included in the network topology building device 200 shown below are described in detail below. Figure 2The hardware structure of a network topology building device is illustrated using the network topology building device 200 shown as an example. Figure 2 As shown, the network topology building 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, memory 203, and communication interface 204 can be connected via the communication line 202.

[0054] 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 embodiments of the present disclosure, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs).

[0055] Communication line 202 may include a path for transmitting information between the aforementioned components.

[0056] The communication interface 204 is used to communicate with other devices or communication networks. It can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0057] The memory 203 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium capable of including or storing desired program code having the form of instructions or data structures and accessible by a computer, but not limited thereto.

[0058] In one possible design, the memory 203 can exist independently of the processor 201, meaning the memory 203 can be an external memory of the processor 201. In this case, the memory 203 can be connected to the processor 201 via a communication line 202 to store execution instructions or application code, and its execution is controlled by the processor 201 to implement the network topology construction method provided in the following embodiments of this disclosure. In another possible design, the memory 203 can also be integrated with the processor 201, meaning the memory 203 can be an internal memory of the processor 201. For example, the memory 203 can be a cache, which can be used to temporarily store some data and instruction information.

[0059] As one possible implementation, processor 201 may include one or more CPUs, for example Figure 2 CPU0 and CPU1 in the example. Alternatively, the network topology building device 200 may include multiple processors, such as CPU0 and CPU1. Figure 2 The processors 201 and 207 are included. Alternatively, the network topology building apparatus 200 may also include an output device 205 and an input device 206.

[0060] The following provides a detailed description of a network topology construction method provided by embodiments of this disclosure.

[0061] like Figure 3 As shown, Figure 3 This disclosure provides a network topology construction method, which can be applied to, for example... Figure 2 The network topology building device shown includes the following steps S301-S303, which will be described in detail below.

[0062] S301, The network topology building device receives a network topology building request from the first terminal.

[0063] The network topology setup request includes: network topology structure; the network topology structure is used to represent multiple network devices in the network topology and the connection relationships between multiple network devices;

[0064] In one possible implementation, the network topology building device determines the network devices used when building the network topology based on the network topology structure.

[0065] S302, The network topology building device determines multiple VXLAN switches based on the network topology structure.

[0066] Multiple VXLAN switches are connected to multiple network devices via physical lines; multiple VXLAN switches are used to realize the connection relationship between multiple network devices.

[0067] In one possible implementation, the VXLAN switch is connected to different network devices via routing lines. The network setup device determines the multiple network devices that need to be used based on the network topology and determines the multiple VXLAN switches that are connected to the multiple network devices.

[0068] S303, The network topology building device sends the first instruction information to multiple VXLAN switches.

[0069] The first instruction information is used to build a VXLAN tunnel between multiple VXLAN switches; the VXLAN tunnel is used to connect network devices through multiple VXLAN switches to build a network topology.

[0070] In one possible implementation, the network topology building device sends a first instruction message to multiple VXLAN switches, instructing the multiple VXLAN switches to enable the Layer 2 Virtual Private Network (L2VPN) function, and build VXLAN tunnels between the multiple VXLAN switches, thereby realizing the connection between network devices and building the network topology.

[0071] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The network topology building device first receives a network topology building request from a first terminal; based on the network topology structure in the network topology building request, it determines the network devices used to build the network topology, then determines multiple VXLAN switches connected to the network devices via physical lines, and instructs the multiple VXLAN switches to build VXLAN tunnels. The network devices are connected based on the VXLAN tunnels to build the network topology. In this way, when the user's network topology requirements change, it is not necessary to remove the physical lines. Only the original VXLAN tunnels need to be disconnected, and a new VXLAN tunnel can be built based on the user's network topology requirements to realize the network topology building. This avoids fiber optic loss and reduces the cost of network topology building, thereby solving the technical problems that the network topology lines are relatively complex, redeploying physical lines can easily cause fiber optic loss, and the cost of building network topology in network laboratories is high.

[0072] In one possible implementation, combining Figure 3 ,like Figure 4 As shown, the process of determining multiple VXLAN switches based on the network topology structure in S302 above can be specifically implemented through the following S401-S402, which will be explained in detail below.

[0073] S401, The network topology building device determines the network devices used to build the network topology based on the network topology structure, and / or the ports of the network devices.

[0074] In one possible implementation, the network device requested in the network topology setup request of the first terminal can be one or more network devices, or it can be a port of one or more network devices.

[0075] For example, the network devices in the network topology are numbered C01, C02, C03, and C04. Among them, network devices C01, C02, and C03 are used exclusively, and network device C04 uses only the port of the XX network device. Then the network topology building device determines that the network devices used to build the network topology are the ports of network devices C01, C02, C03, and the XX network device of network device C04.

[0076] S402, The network topology building device identifies at least one VXLAN switch that has a connection relationship with the network device, and / or at least one VXLAN switch that has a connection relationship with the port of the network device.

[0077] In one possible implementation, the network topology building apparatus determines at least one VXLAN switch connected to the network devices via routing lines.

[0078] For example, if the network topology building device determines that the network devices used to build the network topology are network devices C01, C02, C03, and the port of the XX network device of network device C04, then the network topology building device determines the VXLAN switch connected to network device C01 via a routing line, the VXLAN switch connected to network device C01 via a routing line, the VXLAN switch connected to network device C02 via a routing line, the VXLAN switch connected to network device C03 via a routing line, and the VXLAN switch connected to the port of the XX network device of network device C04 via a routing line.

[0079] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the network topology structure in the network topology request of the network topology building device determines the network device used to build the network topology, and / or the port of the network device, and determines at least one VXLAN switch that has a connection relationship with the network device, and / or at least one VXLAN switch that has a connection relationship with the port of the network device, so that the network topology building device can build the network topology through the VXLAN switch.

[0080] In one possible implementation, combining Figure 4 ,like Figure 5As shown, before the network topology building device receives the network topology building request from the first terminal in S301, it needs to determine whether the network device is currently available. This process can be implemented in detail in the following S501-S503.

[0081] S501, The network topology building device receives a first network device call request from the first terminal.

[0082] The first network device call request is used to request the use of a network device.

[0083] In one possible implementation, before sending a network topology building request to the network topology building device, the first terminal sends a first network device call request to the network topology building device to determine whether the network device is currently available.

[0084] S502, The network topology building device determines whether the network devices are currently available based on the network device database.

[0085] In one possible implementation, the network topology building device determines the network device used by the first terminal based on the first network device call request, and determines whether the network device requested by the first terminal is currently available according to the network device database.

[0086] For example, the network topology building device determines, based on the first network device call request, that the network devices used by the first terminal are network devices C01, C02, C03, and C04, and determines whether network devices C01, C02, C03, and C04 are currently available according to the usage status of network devices C01, C02, C03, and C04 in the network device database.

[0087] S503. When the network topology building device determines that the network equipment is currently available, it sends a first response message to the first terminal.

[0088] The first response information is used to grant the first terminal permission to use the network device.

[0089] For example, the network topology building device determines, based on the first network device call request, that the network devices used by the first terminal are network devices C01, C02, C03, and C04, and determines the usage status of network devices C01, C02, C03, and C04 according to the network device database. If all of them are in an idle state, the device determines that the network devices are currently available, sends a first response message to the first terminal, and grants the first terminal permission to use the network devices.

[0090] The technical solution provided by the above embodiments can bring at least the following beneficial effects: Before receiving a network topology building request from a first terminal, the network topology building device receives a first network device call request from the first terminal. If it is determined that the network device requested by the first terminal is available, the device grants the first terminal the permission to use the network device, so that the first terminal sends a network topology building request to the network topology building device based on the permission to use the network device.

[0091] One possible implementation is, such as Figure 6 As shown, the network topology building device also needs to build a network device database. This process can be implemented through the following steps S601-S602, which will be explained in detail below.

[0092] S601, The network topology building device obtains information on currently available network devices.

[0093] The network device information includes: the network device, the network device's usage status, the network device's port, and the usage status of the network device's port.

[0094] In one possible implementation, the network devices are located in the network laboratory, and the network topology building device obtains information on the network devices currently available in the network laboratory from the network laboratory management system.

[0095] S602, The network topology building device constructs a network device database based on network device information.

[0096] In one possible implementation, the network topology building device acquires information about network devices in the network laboratory, their usage status, ports, and port usage status, and then constructs a network device database based on these information.

[0097] In one possible implementation, after building a network device database, the network topology building device displays the currently available network devices and their ports through a visual interface.

[0098] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the network topology building device obtains information on currently available network devices and builds a network device database based on the network device information, so that the network topology building device can determine whether the network devices are currently available based on the network device database.

[0099] One possible implementation is, such as Figure 7As shown, after the network topology building device sends the first instruction information to multiple VXLAN switches in S303 above, the network topology building device can instruct the second terminal to use the network device. This process can be specifically implemented through the following S701-S703, which will be described in detail below.

[0100] S701, The network topology building device receives a second network device call request from the second terminal.

[0101] The second network device call request includes: the second time period during which the second terminal uses the network device.

[0102] In one possible implementation, after the first terminal uses the network device to build a network topology, when the second terminal needs to use the network device, it sends a second network device call request to the network topology building device. The second network device call request includes a second time period during which the second terminal uses the network device.

[0103] For example, after the first terminal uses the network device to build a network topology, when the second terminal needs to use the network device, it sends a second network device call request to the network topology building device. The second network device call request includes a second time period for the second terminal to use the network device, which is from August 14th to September 15th.

[0104] S702, The network topology building device determines whether the network equipment is idle in the second time period.

[0105] In one possible implementation, the first network device call request includes a first time period during which the first terminal uses the network device, and the network topology building device determines whether the network device is idle in a second time period based on the first time period during which the first terminal uses the network device.

[0106] S703, The network topology building device generates a second response message when it is determined that the network device is idle in the second time period.

[0107] The second response information is used to instruct the second terminal to use the network device.

[0108] In one possible implementation, if the network topology building device determines that the network device is idle during the second time period when the first terminal does not use the network device during the second time period, it generates a second response message to instruct the second terminal to use the network device during the second time period.

[0109] The technical solution provided by the above embodiments can bring at least the following beneficial effects: After receiving a second network device call request from a second terminal, the network topology building device determines whether the network device is idle during the second time period when the second terminal uses the network device. If it is determined that the network device is idle, a second response information is generated to instruct the second terminal to use the network device during the second time period, thereby improving the utilization rate of the network device.

[0110] In one possible implementation, the first network device call request includes: a first time period during which the first terminal uses the network device, combined with... Figure 7 ,like Figure 8 As shown, the process by which the network topology building device determines whether a network device is idle in the second time period, as described above in S702, can be specifically implemented through the following S801-S803, which will be explained in detail below.

[0111] S801, The network topology building device determines whether there is an overlap between the second time period and the first time period.

[0112] In one possible implementation, the network topology building device determines a first time period for the first terminal to use the network device based on a first network device call request from a first terminal, determines a second time period for the second terminal to use the network device based on a second network device call request from a second terminal, and determines whether there is an overlap between the second time period and the first time period.

[0113] S802. If the network topology building device determines that the network equipment is idle in the second time period if there is no overlap between the second time period and the first time period, the network topology building device determines that the network equipment is idle in the second time period.

[0114] For example, the network topology building device determines, based on a first network device call request from a first terminal, that the first time period for the first terminal to use the network device is from August 1st to August 10th and from September 16th to December 30th; the network topology building device determines, based on a second network device call request from a second terminal, that the second time period for the second terminal to use the network device is from August 14th to September 15th. In this case, the network topology building device determines that the second time period does not overlap with the first time period, and the network device is idle during the second time period.

[0115] S803. When the network topology building device determines that there is an overlap between the second time period and the first time period, it determines that the network equipment is not idle in the second time period.

[0116] For example, if the network topology building device determines, based on a first network device call request from a first terminal, that the first time period for the first terminal to use the network device is from August 1st to December 30th; and if the network topology building device determines, based on a second network device call request from a second terminal, that the second time period for the second terminal to use the network device is from August 14th to September 15th, then the network topology building device determines that the second time period overlaps with the first time period, and the network device is not idle during the second time period.

[0117] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the network topology building device determines the first time period for the first terminal to use the network device based on the first network device call request from the first terminal, and determines the second time period for the second terminal to use the network device based on the second network device call request from the second terminal. It determines whether the network device is idle in the second time period based on whether there is an overlap between the second time period and the first time period. This allows the network topology building device to generate a second response information to instruct the second terminal to use the network device in the second time period when it is determined that the network device is idle in the second time period, thereby improving the utilization rate of the network device.

[0118] One possible implementation is, such as Figure 9 As shown, before the network topology building device generates the second response information in the case that the network device is in an idle state in the second time period, in the above-mentioned S703, the network topology building device also needs to release the network device. This process can be implemented in detail in the following S901-S902.

[0119] S901, The network topology building device stores a snapshot of the network topology when it is determined that the network equipment is in an idle state.

[0120] The snapshot is used to restore the network topology after the second terminal finishes using the network device.

[0121] In one possible implementation, the network topology building device saves a snapshot of the network topology built by the first terminal based on snapshot storage technology. After the second terminal finishes using the network device, the network topology built by the first terminal is restored based on the snapshot of the network topology built by the first terminal.

[0122] S902, The network topology building device sends a second instruction message to multiple VXLAN switches.

[0123] The second instruction information is used to instruct multiple VXLAN switches to disconnect the VXLAN tunnel and release the network devices.

[0124] In one possible implementation, the network topology building device saves a snapshot of the network topology structure built by the first terminal, and sends a second instruction message to multiple VXLAN switches, instructing the multiple VXLAN switches to disconnect the VXLAN tunnel and release the network devices so that the second terminal can use the network devices.

[0125] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the network topology building device saves a snapshot of the network topology structure built by the first terminal, sends a second instruction message to multiple VXLAN switches, instructing the multiple VXLAN switches to disconnect the VXLAN tunnel and release the network devices so that the second terminal can use the network devices, and can quickly restore the network topology built by the first terminal based on the snapshot of the network topology structure built by the first terminal after the second terminal finishes using the network devices.

[0126] One possible implementation is, such as Figure 10 As shown, Figure 10 This is a schematic diagram of the modules included in a network topology building device provided in an embodiment of the present disclosure. The network topology building device includes: a resource input module 1001, a resource application module 1002, a topology establishment module 1003, and a topology switching module 1004.

[0127] The resource entry module 1001 is used to obtain information on currently available network devices and construct a network device database based on the network device information; the resource application module 1002 is used to process network device call requests from terminals and allocate network devices based on the network device call requests; the topology establishment module 1003 is used to receive network topology building requests from terminals and build a network topology based on the network topology building requests; and the topology switching module 1004 is used to reallocate network devices and rebuild the network topology when a new network device call request is received.

[0128] One possible implementation is, such as Figure 11 As shown, Figure 11 This is another network topology construction method provided in the embodiments of the present disclosure. The process specifically includes the following S1101-S1105. The specific implementation of this process has been described in detail and will not be repeated here.

[0130] S1102. Receive a network device call request from the terminal and determine the port or network device used by the terminal.

[0131] S1103. Determine whether it is necessary to disconnect the old network topology and release the allocated network devices when building the network topology. If not, proceed to S1104; if yes, proceed to S1105.

[0132] S1104. Receive a network topology setup request from the terminal and set up a network topology based on the VXLAN switch.

[0133] S1105: Back up a snapshot of the old network topology, release network devices, receive network topology setup requests from terminals, and build a network topology based on the VXLAN switch.
