[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Combine the following Figure 1-Figure 3 The present invention describes a method, device and electronic device for determining network topology.

[0022] Figure 1 is a flow chart of the network topology determination method provided by the present invention, such as Figure 1 As shown, the network topology determination method includes steps S100 to S500, and each step is specifically described as follows.

[0023] S100: When network element devices are located in the same domain in the network, first connection information between the network element devices is obtained from a network management system corresponding to the same domain.

[0024] The operator's network has multiple domains, such as wireless domain, microwave domain, IP domain, transmission domain, core network domain, etc. One network management system manages one domain. Optionally, one domain is managed by multiple network management systems. Network element devices are devices connected to the network management system, such as wireless devices, microwave devices, data communication devices, transmission devices, core network devices, etc.

[0025] The execution subject of the embodiment of the present invention is a resource management system, which is used to manage the connection information between network element devices in different network management systems and between network element devices and external devices.

[0026] The first connection information between network element devices is obtained from the network management system corresponding to the same domain. Specifically, a configuration table of the network management system is obtained; the configuration table pre-stores the port information of the network element devices of the network management system and the connection relationship between the ports of the network element devices; based on the configuration table, the port information of the network element devices and the connection relationship between the ports of the network element devices are obtained to obtain the first connection information.

[0027] The network management system includes a configuration table, in which port information of network element devices of the network management system and connection relationships of ports of the network element devices are pre-stored. For example, if the network management system manages multiple microwave devices, the configuration table stores port information of each microwave device and connection relationships between microwave devices. Directly acquiring the configuration table of the network management system can obtain the first connection information of network element devices in the same domain corresponding to the network management system.

[0028] Acquiring the first connection information through the configuration table improves the accuracy and efficiency of acquiring the first connection information.

[0029] S200: When the network element devices are located in different domains and a network protocol exists between the network element devices, second connection information between the network element devices is obtained based on the network protocol.

[0030] When the network element devices are located in different domains and a network protocol exists between the network element devices, the second connection information between the network element devices is obtained based on the network protocol. Specifically, the media access control MAC addresses of the two communicating network element devices are respectively obtained based on the network protocol to obtain the second connection information.

[0031] When network element devices are located in different domains and there is a network protocol between the network element devices, the Media Access Control (MAC) addresses of the two communicating network element devices are directly obtained according to the network protocol. The network protocol is the Link Layer Discovery Protocol (LLDP). For example, the Network Element Configuration - IP Network Management (NCE-IP) system can obtain the second connection information between the microwave equipment connected to the data communication equipment and the leased third-party equipment through LLDP. Through LLDP, the second connection information between two network element devices in different domains can be obtained, or the second connection information between the network element device in the network management system and the external equipment (for example, leased third-party equipment) can be obtained.

[0032] The resource management system (for example, NCE-IP system) can learn the MAC addresses of two network element devices connected in different domains through LLDP, and then obtain the cross-domain link between the two network element devices connected in different domains. For example, the MAC address corresponding to the wireless device port connected to the microwave device can be obtained through the LLDP protocol, thereby obtaining the cross-domain link between the wireless device and the microwave device.

[0033] The second connection information is obtained through the network protocol, so that the communication relationship between network element devices in different domains can be obtained efficiently and accurately, which is conducive to the comprehensive construction of the network topology map.

[0034] S300: When the network element devices are located in different domains and no network protocol exists between the network element devices, third connection information between the network element devices is acquired based on the first configuration information.

[0035] When network element devices are located in different domains and there is no network protocol between the network element devices, the two network element devices that communicate with each other are managed by different network management systems respectively, and the third connection information between the two network element devices cannot be automatically obtained according to the unified network management system. Since the two network element devices that communicate with each other are at different protocol stack layers, no network protocol can collect the third connection information across different protocol stack layers. For example, the network element devices in the Optical Transport Network (OTN) belong to the L1 physical layer, the network element devices in the IP Metropolitan Area Network (IP-Metro) belong to the L2 link layer, and the network element devices in the IP core network belong to the L3 IP layer. Currently, there is no network protocol that can collect data across the L1 physical layer and the L2 link layer or across the L1 physical layer and the L3 IP layer. To obtain the third connection information between network element devices that are located in different domains and do not have a network protocol, it is necessary to set the corresponding first configuration information in advance on the network management systems corresponding to the two communicating network element devices, so that the resource management system can automatically collect the third connection information according to the first configuration information.

[0036] The first configuration information is used to describe the port information and connection relationship of two network element devices located in different domains and without a network protocol.

[0037] S400: When the external device needs to communicate with the network element device in the network management system, fourth connection information between the preset network element device and the external device is obtained based on the second configuration information.

[0038] The external device is a device that is not managed by the network management system, such as a leased third-party device. At this time, it is impossible to obtain the information of the external device from the network management system, and it is even more impossible to obtain the fourth connection information between the external device and the network element device in the network management system. At this time, the second configuration information can be set on the network management system corresponding to the network element device that the external device needs to communicate with according to the customer's requirements. The second configuration information is used to describe the port information and connection relationship between the external device and the network element device.

[0039] S500: Construct a network topology map based on the first connection information, the second connection information, the third connection information and the fourth connection information.

[0040] The network element devices and / or external devices for which a network topology diagram needs to be constructed are converted into topology points, and the connections between the topology points are constructed according to the first connection information, the second connection information, the third connection information and the fourth connection information, so as to finally obtain a network topology diagram.

[0041] The network topology diagram of the present invention includes topological connections between devices in the same domain, different domains, and the outside world. For example, topological connections between wireless devices, topological connections between wireless devices and microwave devices, topological connections between wireless devices and data communication devices, topological connections between microwave devices and data communication devices, topological connections between data communication devices and transmission devices, etc.

[0042] The network topology determination method provided by the present invention automatically obtains the first connection information through the network management system, thereby realizing the automatic acquisition of the first connection information. The second connection information is obtained according to the network protocol, thereby improving the efficiency of obtaining the second connection information. According to the first configuration information, the third connection information of the network element device in different domains and without the network protocol is obtained, which is conducive to enriching the domains involved in the network topology map. According to the second configuration information, the fourth connection information between the external device and the network element device is obtained, which is conducive to improving the comprehensiveness of the network topology map. The present invention constructs a network topology map according to the first connection information, the second connection information, the third connection information and the fourth connection information, thereby realizing the construction of the network topology structure between the same domain, different domains and the external devices, making the network topology map more comprehensive.

[0043] Based on the above embodiment, when the network element devices are located in different domains and there is no network protocol between the network element devices, the third connection information between the network element devices is obtained based on the first configuration information, including steps S310 to S320, and each step is specifically as follows.

[0044] S310: Store the port information of the second device that needs to communicate in the port of the first device, or store the port information of the first device in the port of the second device to determine the first configuration information. The first device and the second device are two network element devices that need to communicate and are located in different domains and do not have a network protocol. The port is used to connect the network element device and the corresponding network management system; network element devices in different domains are connected to different network management systems.

[0045] S320: Acquire first configuration information from a port of the first device or a port of the second device based on a setting program to acquire third connection information.

[0046] The network element device is connected to the network management system through a port. When two network element devices in different domains and without a network protocol need to communicate, the two network element devices are the first device and the second device respectively. The network management system stores the port information of the second device in the port of the first device, or the network management system stores the port information of the first device in the port of the second device, thereby obtaining the first configuration information. For example, the first device is a wavelength division multiplexing (WDM) device, and the second device is an IP device. The port information of the connected IP device is added to the description field of the port of the WDM device, thereby obtaining the first configuration information. The first configuration information includes an IP device name, an IP device number (for example, a rack number of the IP device, a slot number of the IP device, etc.), and a port number of the IP device. For example, the first configuration information is set in the port of the WDM device. WDM port identifier (to IP device): to IP device IP device name / IP device rack number / IP device slot number / IP device sub-slot number / IP device port number / connection information. Among them, "to IP device" is a setting field. “IP device name / IP device rack number / IP device slot number / IP device sub-slot number / IP device port number / connection information” is the first configuration information.

[0047] Alternatively, add the port information of the connected WDM device to the description field of the port of the IP device to obtain the first configuration information. At this time, the first configuration information includes the WDM device name, the WDM device number (for example, the rack number of the WDM device, the slot number of the WDM device, etc.) and the port number of the WDM device. Add a setting field before the first configuration information. The resource management system accesses the setting field of the port of the first device in the network management system corresponding to the first device according to the setting program to obtain the first configuration information (the port information of the second device). The resource management system obtains the port information of the first device from the network management system corresponding to the first device.

[0048] Alternatively, the resource management system accesses the setting field of the port of the second device in the network management system corresponding to the second device according to the setting program to obtain the first configuration information (port information of the first device). The resource management system obtains the port information of the second device from the network management system corresponding to the second device.

[0049] The resource management system obtains third connection information between the first device and the second device, which are located in different domains and have no network protocol, according to the port information of the first device and the port information of the second device.

[0050] The present invention stores the port information of the second device in the port of the first device or stores the port information of the first device in the port of the second device, thereby realizing the construction of a configuration relationship between two network element devices in different domains and without a network protocol, and further realizing automatic acquisition of the third connection information from the network management system, thereby improving the efficiency of acquiring the third connection information.

[0051] Based on the above embodiment, when an external device needs to communicate with a network element device in a network management system, fourth connection information between the network element device and the external device is obtained based on the second configuration information, including steps S410 to S420, and each step is specifically as follows.

[0052] S410: Store the port information of the external device on the port of the network element device to determine the second configuration information.

[0053] S420: Acquire second configuration information from a port of the network element device based on a setting program to obtain fourth connection information.

[0054] The second configuration information is obtained from the port of the network element device based on the setting program. Specifically, according to the result of the setting program accessing the setting field in the port of the network element device, the name of the external device, the number of the external device and the port number of the external device are obtained to obtain the second configuration information.

[0055] When an external device communicates with a network element device in a network management system, since the external device does not match the network management system, the second configuration information cannot be set in the port of the external device through the network management system. At this time, the port information (second configuration information) of the external device can be set and stored on the port of the network element device connected to the external device through the network management system. The second configuration information includes the name of the external device, the number of the external device, and the port number of the external device. A setting field is set in front of the second configuration information. The resource management system accesses the setting field in the port of the network element device according to the setting program to obtain the second configuration information (port information of the external device). The resource management system obtains the port information of the network element device from the network management system, and obtains the fourth connection information according to the port information of the external device and the port information of the network element device.

[0056] The present invention stores the port information of the external device in the port of the network element device, thereby building a configuration relationship between the external device and the network element device, and then automatically obtaining the fourth connection information from the network management system, thereby improving the efficiency of obtaining the fourth connection information.

[0058] The second connection information acquisition module 202 is configured to acquire second connection information between network element devices based on the network protocol when the network element devices are located in different domains and a network protocol exists between the network element devices.

[0059] The third connection information acquisition module 203 is used to acquire third connection information between network element devices based on the first configuration information when the network element devices are located in different domains and no network protocol exists between the network element devices.

[0060] The fourth connection information acquisition module 204 is used to acquire fourth connection information between the network element device and the external device based on the second configuration information when the external device needs to communicate with the network element device in the network management system.

[0061] The topology construction module 205 is used to construct a network topology map based on the first connection information, the second connection information, the third connection information and the fourth connection information.

[0062] The network topology determination device provided by the embodiment of the present invention automatically obtains the first connection information through the network management system, thereby realizing the automatic acquisition of the first connection information. The second connection information is obtained according to the network protocol, thereby improving the efficiency of obtaining the second connection information. According to the first configuration information, the third connection information of the network element device in different domains and without the network protocol is obtained, which is conducive to enriching the domains involved in the network topology map.
