Fig. 2 is a schematic diagram of a network topology drawing process in the prior art. As shown in fig. 2, the engineering personnel performs network construction according to the construction design to complete network construction. And the user records the information such as the machine room position, the equipment information, the network parameters and the like according to the construction condition, and performs information input in the network management system. The network management system generates a basic network topology. When the user feeds back the broadband fault, engineering personnel need to manually check from the user side (corresponding to the user equipment) to the network element side (corresponding to the network element) and manually locate the fault.

In the traditional technology, the network topology drawing and maintenance mode is performed manually, and as the network construction becomes more and more complex, the maintenance difficulty of the network topology graph is also increased. Meanwhile, in the traditional technology, the service and the grid are mutually isolated, and when a user declares a fault, multi-dimensional hierarchical inquiry is needed, so that the fault acceptance efficiency is low.

The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 3 is a schematic architecture diagram of a network topology drawing system according to an embodiment of the present application. As shown in fig. 3, the network topology drawing system may include: the device comprises a capability interface, a computing unit, a first signal receiving and transmitting module, a first signal analysis module, a drawing tool, a second signal receiving and transmitting module and a second signal analysis module.

As shown in fig. 3, the capability interface, the computing unit, the first signal transceiver module, the first signal analysis module and the drawing tool are deployed in the network management system.

The capability interface can be used for acquiring service information of the user. Wherein the traffic information may represent information related to the user network service. The embodiment of the application does not limit the service information.

In one possible implementation, as shown in FIG. 3, the capability interface may be coupled to a product system and/or customer relationship management system (Customer Relationship Management system, CRM), and the capability interface may be used to obtain business information from the product system and/or customer relationship management system. In one example, the product system may be a cloud product management system. The capability interface may obtain customer cloud service information from the product system and customer base business information from the customer relationship management system. The acquired customer cloud service information and customer base service information are the service information of the user.

And the calculation unit can be used for generating a network check instruction and a network parameter check packet according to the service information. Wherein, the network check instruction can be used for indicating to perform data check; the network parameter verification package may verify that the network parameters meet the business criteria handled by the user. The manner in which the computing unit generates the network check instruction and the network parameter check packet according to the service information may refer to related technologies, and will not be described herein.

The first signal transceiver module can be used for sending a network check instruction and a network parameter check packet to a network element at a user gateway side. The network verification instruction may be sent in an optical signal manner or may be sent in an electrical signal manner, which is not limited in this embodiment of the present application.

In the embodiment of the application, the network elements at the user gateway side include, but are not limited to, backbone network elements, network element equipment and user gateways. In the embodiment of the application, the number and types of the network elements included in the network element at the user gateway side are not limited. After the network element at the user gateway side receives the network check instruction and the network parameter check packet, the network parameter check packet can be checked based on the network check instruction to obtain a check result corresponding to the network element.

As shown in fig. 3, the second signal transceiver module and the second signal analysis module are disposed in a network element on the user gateway side. Specifically, the second signal transceiver module and the second signal analysis module are disposed in pairs in the network element at the user gateway side. That is, as shown in fig. 3, a pair of second signal transceiver modules and second signal analysis modules are disposed in each backbone network element, a pair of second signal transceiver modules and second signal analysis modules are disposed in each network element device, and a pair of second signal transceiver modules and second signal analysis modules are disposed in each subscriber gateway.

For any network element, the second signal transceiver module may be configured to receive a network check instruction and a network parameter check packet. The second signal analysis module can be used for collecting the equipment information of the network element based on the network verification instruction and generating a verification result corresponding to the network element based on the equipment information and the network parameter verification packet. The second signal transceiver module may be further configured to return a verification result and a sequence number corresponding to the network element to the network management system.

The device information of the network element may include a device number, port information, a machine room address, and the like. The second signal analysis module can compare the network parameters with the network parameter verification packages based on the network verification instructions, and verify whether the network parameters meet the service standards handled by users, and network verification such as network delay and equipment information can be packaged to form verification results corresponding to network elements.

In the embodiment of the present application, the network elements on the user gateway side may be classified into two types, one is a peripheral network element, and the other is a non-peripheral network element. If there is no next hop network element in a network element, the network element is a peripheral network element, for example, the user gateway shown in fig. 3 is a peripheral network element. If a next hop element exists in a network element, the network element is a non-peripheral network element (i.e., the network element is not a peripheral network element), such as the backbone network element and the network element equipment shown in fig. 3 are non-peripheral network elements.

In one possible implementation manner, the second signal transceiver module may be configured to forward the network check instruction and the network parameter check packet to a next-hop network element connected to the network element, and receive a check result and a sequence number corresponding to the next-hop network element returned by the next-hop network element, where the network element is not a peripheral network element.

And under the condition that one network element is not a peripheral network element, indicating that the network element has a next-hop network element, and forwarding a network check instruction and a network parameter check packet to the next-hop network element by a second signal receiving and transmitting module deployed on the network element. After the next hop network element receives the network check instruction and the network parameter check packet, the second signal analysis module deployed on the next hop network element can generate a corresponding check result based on the just-dropped check instruction and the network parameter check packet, and return the corresponding check result and the sequence number.

In case that one network element is not a peripheral network element, it receives the check result and the sequence number returned by the next hop network element. At this time, the network element can bind the verification result and the serial number corresponding to the network element and the verification result and the serial number returned by the next-hop network element and then return to the network management system together.

And under the condition that one network element is a terminal network element, the condition that the network element does not have a next-hop network element is indicated, and a second signal receiving and transmitting module deployed on the network element does not need to forward a network check instruction and a network parameter check packet, and the network element also does not receive a check result and a sequence number returned by the next-hop network element. Therefore, the network element can return the verification result and the serial number corresponding to the network element to the network management system.

It can be understood that, in the embodiment of the present application, the path of the check result and the sequence number returned to the network management system is opposite to the forwarding path of the network check instruction and the network parameter check packet.

In the embodiment of the application, the sequence number corresponding to the next-hop network element indicates the forwarding times of the network check instruction and the network check packet when the next-hop network element receives the network check instruction and the network parameter check packet. Correspondingly, the sequence numbers corresponding to the network elements represent the forwarding times of the network check instructions and the network check packets when the network elements receive the network check instructions and the network parameter check packets. The sequence number corresponding to the last hop network element indicates the forwarding times of the network check instruction and the network check packet when the last hop network element receives the network check instruction and the network parameter check packet. That is, the sequence number is incremented by one for each forwarding of the network check instruction and the network check packet.

For example, suppose that the network management system connects network element 1 and network element 2 in sequence, wherein network element 1 and network element 2 are not peripheral network elements and network element 2 is a peripheral network element. Firstly, the network management system sends a network check instruction and a network parameter check packet to the network element 1, and the forwarding times of the network check instruction and the network parameter check packet are 1 at this time, so that the serial number of the network element 1 is 1. The network element 1 generates a verification result corresponding to the network element 1 based on the network verification instruction and the network parameter verification packet on one hand, and forwards the network verification instruction and the network parameter verification packet to the network element 2 on the other hand. At this time, the number of times of forwarding the network check instruction and the network parameter check packet is 2, so the sequence number of the network element 2 is 2. The network element 2 generates a verification result corresponding to the network element 21 based on the network verification instruction and the network parameter verification packet. And then, the network element 2 returns a verification result corresponding to the network element 2 and the sequence number 2 to the network element 1. The network element 1 returns a verification result and a serial number 1 corresponding to the network element 1 and a verification result and a serial number 2 corresponding to the network element 2 to the network management system.

So far, the network element at the user gateway side returns the network element verification result to the network management system. The network element verification result comprises a network verification instruction, a verification result and a sequence number corresponding to each network element through which the network parameter verification packet passes at the user gateway side. And then, the network element verification result is further processed by the network management system.

The first signal transceiver module may be further configured to receive a network element verification result returned by the network element at the user gateway side.

The first signal analysis module can be used for determining the physical relationship and the physical distance of each network element according to the verification result and the serial number corresponding to each network element. For example, the network elements of adjacent sequence numbers represent their physical direct connections, and the addresses of the network elements in the check result can determine the physical distance.

And the drawing tool can be used for generating a network topological graph of the user according to the physical relationship and the physical distance of each network element. The drawing tool can apply a computing unit and network data to combine with a digital twin algorithm to draw the network topology secondarily to form a single-user network physical topological graph. Here, the application calculation unit means that the calculation unit is used to perform drawing calculation, and analyzes the physical topological relation, sequence, coordinates, and the like between the network elements.

In one possible implementation, the network topology drawing system may further include a user network topology database (not shown). The drawing tool is further used for generating a network element relation list according to the physical relation and the physical distance of each network element; and storing the network topology graph and the network element relation list into a user network topology database.

In one possible implementation, as shown in fig. 3, the network topology drawing system may further include a data cache repository. The data exchange storage warehouse can be used for temporarily storing business information of users, data (such as physical relations, physical distances and the like) required by network topology drawing of the users, and finally synchronizing the completed drawing into a network topology database of the users.

According to the network topology drawing system provided by the embodiment of the application, business information related to the user network service is obtained through the capability interface of the network management system and is cached to the data cache warehouse. The service information generates a network check instruction and a network parameter check packet through a computing unit, and the network check instruction and the network parameter check packet are pushed to a network element at a user gateway side through a first signal receiving and transmitting module.

And then, after receiving the network check instruction and the network parameter check packet pushed by the network management system, the second signal receiving and transmitting module on the network element of each user gateway side judges whether the network element is a terminal network element. If not, continuing to forward the network check instruction and the network parameter check packet to the next hop network element; meanwhile, the second signal receiving and transmitting module transmits the network check instruction and the network parameter check packet to the second signal analysis module. The second signal analysis module collects the equipment information of the local network element based on the network verification instruction, and forms a verification result corresponding to the local network element based on the equipment information of the local network element and the network parameter verification packet. If yes, the second signal analysis module of the local network element packs the corresponding check result and sequence number of the local network element to return to the network management system in the original path, and the second signal analysis module of the passing network element packs the corresponding check result and sequence number of the local network element and the check result and sequence number returned by the last hop network element in a binding way, and continues to return in the original path.

Finally, a first signal analysis module of the network management system recovers the verification result and the serial number, analyzes the verification result and the serial number to obtain a sorting result, and pushes the sorting result to a drawing tool. The drawing tool application calculation unit draws the network topological graph, simultaneously generates a network element relation list, and stores the network topological graph and the network element relation list into the data cache warehouse. The data cache warehouse synchronizes the network topology graph and the network element relation list to a user network topology database of the network management system.

In the embodiment of the application, the network topology graph is not dependent on manual configuration after construction of engineering personnel, and can be directly drawn from the equipment end. The network topology diagram can not only depict the main circuit topology, but also feed back the full-link topology in real time through the channel of the data packet. The network topology drawing method provided by the embodiment of the application can be implemented by applying the existing algorithm, components and middleware to the network management system and each network element to deploy each module. In addition, the physical topological relation between network elements is formed by taking comprehensive resources and service data as main materials, the front-end information view of a user-product-package is formed by taking CRM data as main materials, and an end-to-end data map model of an optical access IP resource network is formed by mapping resources and services, so that a user end is reached from the network element end. Meanwhile, quick traversal and positioning are realized, fault influence range calculation and cluster statistics extending to a user side are completed, manual intervention control is not needed, and operation and maintenance cost is reduced.

In one embodiment, fig. 4 is a schematic flow chart of a network topology drawing method provided in the embodiment of the present application. Taking the application of the method to the network management system in fig. 3 as an example, as shown in fig. 4, the method may include the following steps:

Wherein the traffic information may represent information related to the user network service. The embodiment of the application does not limit the service information.

In one example, customer cloud service information may be obtained from a product system and customer base business information may be obtained from a customer relationship management system. The acquired customer cloud service information and customer base service information are the service information of the user.
