For example, the processor 101 may be a general-purpose central processing unit (centralprocess ing uni t, CPU), or may be another general-purpose processor.

The bus may be classified as an address bus, a data bus, a control bus, etc. For ease of illustration, only one thick line is shown in fig. 1, but not only one bus or one type of bus.

It should be noted that the structure shown in fig. 1 does not constitute a limitation of the computing device, and the computing device may include more or less components than those shown in fig. 1, or may combine some components, or may be arranged in different components.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 2, a method for creating a network resource model, where the network resource model is used to store connection relationships between different network transmission devices in a network, an execution body of the method may be an electronic device, and the method may include the following steps S201 to S203.

S201: the method comprises the steps of obtaining geographic position information of equipment to be accessed, and creating a new node representing the equipment to be accessed in a network resource model, wherein the network resource model comprises a plurality of nodes and edges connected with different nodes, one node represents one network transmission equipment, and one edge represents a transmission link connected with two network transmission equipment.

It should be understood that, at this time, the new node has null values except for the geographical location information, and the device to be accessed corresponding to the new node is actually a network transmission device not accessed to the network. That is, the new node is an isolated node in the network resource model that has no connection relationship with other nodes. And other nodes in the network resource model represent network transmission equipment which is accessed to the network, and different nodes in the nodes are connected through at least one edge so as to represent the connection relation between the different network transmission equipment.

In one possible embodiment, the node locations in the network resource model have a mapping relationship with the actual geographical locations of the network transmission devices.

For example, the network resource model is constructed in a map-like form. In the network resource model, according to the geographic position information of the equipment to be accessed, a new node is created at a coordinate position corresponding to the geographic position information of the equipment to be accessed and becomes the node therein.

As can be seen from the above embodiments, the network resource model related to the present application is constructed based on the connection relationship between the network transmission device and the transmission link in the actual network. Further, network transmission devices and transmission links may also be constructed based on the geographic location information. In this way, the network resource model constructed by the method has the logical relation information (or connection relation information) of the network transmission equipment and the transmission link, and simultaneously has the corresponding position relation information, so that the network topology structure formed by the network transmission equipment and the transmission link can be intuitively reflected.

S202: the method comprises the steps of determining a node serving as a network access point of equipment to be accessed in a network resource model, inquiring target network transmission equipment between the equipment to be accessed and the network access equipment in an information database according to geographic position information of the equipment to be accessed and geographic position information of the network access equipment, wherein the network access equipment is network transmission equipment represented by the network access point, and the information database comprises connection relations and geographic position relations among all network transmission equipment in a network.

In one possible implementation, the node that is the network access point for the device to be accessed may be determined based on geographic factors. For example, according to the geographical position information of the device to be accessed, searching the node closest to the new node in the network resource model, and taking the node as a network access point, wherein the network transmission device corresponding to the network access point is the network access device.

Of course, the node that is the network access point of the device to be accessed may also be determined according to other factors. For example, the node with the least number of network transmission devices is used as the network access point of the device to be accessed, and the number of network transmission devices to be accessed is used as a determining factor. The determination of the network access point by geographic factors in this embodiment is merely an example and is not intended to limit the present application.

It should be appreciated that a device to be accessed may need to go through multiple network transmission devices, as well as transmission links, to be able to connect with the network access device. In addition, the device to be accessed is generally the end of the network, and other accessible network transmission devices in the network are already connected to the network, so that in order to enable the device to be accessed to connect to the network, a target network transmission device located between the device to be accessed and the network access device, that is, a network transmission device which can be directly connected to the device to be accessed and is connected to the network access device, is searched in the information database, and the network transmission device is the target network transmission device.

S203: and creating at least one target node in the network resource model according to the at least one target network transmission device, and establishing edges connecting the target node with the new node and the network access point, wherein one target node represents one target network transmission device.

For example, there are a target network transmission device 01 and a target network transmission device 02.

According to the target network transmission device 01, a target node 01 is built in the network resource model, and edges between the new node and the target node 01, and edges between the target node 01 and the network access point are built.

According to the target network transmission device 02, a target node 02 is built in the network resource model, and edges between the new node and the target node 02, and edges between the target node 01 and the network access point are built.

Specifically, as shown in fig. 3, a new node 301 is built in a network resource model and a network access point 302 is determined.

As shown in fig. 4, according to the target network transmission apparatus 01, a target node 401 is established in the network resource model, and edges between the new node 301 and the target node 401, and edges between the target node 401 and the network access point 302 are established.

According to the target network transmission device 02, a target node 402 is built in the network resource model, and edges between the new node 301 and the target node 402, and edges between the target node 402 and the network access point 302 are built.

According to the embodiment, when a new service needs to be opened, a new node representing the equipment to be accessed is created in the network resource model according to the geographic position information of the equipment to be accessed. Thus, in the network resource model at this time, the new node corresponding to the device to be accessed is an isolated node with less information. In order to further expand the network resource model, a target network transmission device between the device to be accessed and the network access device of the device to be accessed is found in the information database, namely, the network transmission device for enabling the device to be accessed to be connected to the network access device is obtained, a target node corresponding to the target network transmission device and an edge for connecting the target node, a new node and the network access point are built in the network resource model, so that the purpose of expanding the network resource model is achieved, and the new node is not an isolated node any more. Therefore, the network resource model creation method provided by the application can gradually expand the network resource model along with the establishment of the new node, so that more information is provided for the establishment of the subsequent new node.

In one possible implementation manner, according to the geographic position information of the device to be accessed and the geographic position information of the network access device, inquiring the target network transmission device between the device to be accessed and the network access device in the information database, including: if the first network transmission equipment is found, the first network transmission equipment is determined to be target network transmission equipment, and the first network transmission equipment is network transmission equipment which is connected with equipment to be accessed through a first transmission link and is connected with network access equipment through a second transmission link.

For example, when there is a transmission link near the geographic location where the device to be accessed is located, such as a reserved transmission link, or an optical fiber transmission link for connecting to a network television, and the transmission link is connected to a first network transmission device, the first network transmission device is connected to the network access device through a second transmission link, then the transmission link is the first transmission link. Thus, the device to be accessed can be connected to the first network transmission device through the first transmission link, and then connected to the network access device through the first network transmission device and the second transmission link.

As can be seen from the above embodiments, the present application may complete access of a device to be accessed according to an existing transmission link, so as to establish a corresponding target node.

In one possible implementation manner, according to the geographic position information of the device to be accessed and the geographic position information of the network access device, the information database is searched for a target network transmission device located between the device to be accessed and the network access device, and the method further includes: if the first network transmission equipment is not found, whether the second network transmission equipment exists is found, wherein the second network transmission equipment is network transmission equipment which comprises equipment to be accessed in a coverage area and is connected with the network access equipment through a third transmission link. And if the second network transmission equipment is found, determining the second network transmission equipment as target network transmission equipment.

It should be understood that the coverage area of a network transmission device refers to a range of sizes preset around the geographical location of the network transmission device, where the device to be accessed in the coverage area has appropriate conditions for accessing the network transmission device.

For example, when there is no existing transmission link near the geographic location where the device to be accessed is located, it may be sequentially queried whether the coverage area of the network transmission device near the device to be accessed contains the device to be accessed according to the sequence from the near to the far away from the device to be accessed. When the network transmission equipment with the coverage area containing the equipment to be accessed is found and is connected with the network access equipment through a third transmission link, the network transmission equipment is the second network transmission equipment, and the second network transmission equipment is determined to be the target network transmission equipment.

The above embodiment determines the second network transmission device as the target network transmission device, but at this time, there is no real connection relationship between the second network transmission device and the device to be accessed, i.e. there is no transmission link between the two. At this time, in the network resource model, the target node corresponding to the second network transmission device and the new node corresponding to the device to be accessed belong to virtual connection, and are used for guiding the device to be accessed to establish real connection with the second network transmission device, namely, a transmission link is established.

As can be seen from the above embodiments, when there is no existing transmission link near the geographic location where the device to be accessed is located, the present application further provides searching for a second network transmission device whose coverage area includes the device to be accessed, so that the device to be accessed uses the second network transmission device as a target network transmission device to connect with the network access device, and finally completes the access of the device to be accessed. By the method, the connection scheme can be provided to guide the construction of the transmission link under the condition that the existing transmission link does not exist near the geographic position of the equipment to be accessed.

In one possible implementation manner, according to the geographic position information of the device to be accessed and the geographic position information of the network access device, the information database is searched for a target network transmission device located between the device to be accessed and the network access device, and the method further includes: if the first network transmission equipment is not found, searching whether third network transmission equipment exists, wherein the third network transmission equipment is network transmission equipment which is connected with fourth network transmission equipment through a fourth transmission link to access a network, and the fourth network transmission equipment is network transmission equipment which comprises equipment to be accessed in a coverage area and is of the same type as the equipment to be accessed. And if the third network transmission equipment is found, determining the third network transmission equipment as target network transmission equipment.

In one possible embodiment, the device to be accessed is within the coverage range of the same device type, and the device to be accessed can also be connected with the network access device through the target network transmission device connected with the network transmission device of the same device type to access the network.

In general, there are various network transmission devices, and the device to be accessed may be a terminal network device, such as a terminal router. The network access device should be a large network transport device such as a convergence layer switch or gigabit-class routing.

The equipment to be accessed is in the coverage range of the fourth network transmission equipment, and the distance between the equipment to be accessed and the fourth network transmission equipment is characterized as being relatively short. The adjacent network transmission device accesses the network via a transmission path to which the third network transmission device is connected, and the device to be accessed can then access the network via a similar transmission path.

In addition, since the device to be accessed is closer to the fourth network transmission device, the device to be accessed may access the network through the same network access device as the fourth network transmission device or a different network access device closer to the fourth network transmission device.

Because the adjacent network access devices are also connected with each other, the network access device of the device to be accessed can be any one of a plurality of adjacent and connected network access devices, and the network access point of the new node is any one of the nodes corresponding to the connected network access devices. The network access device to which the fourth network transmission device is connected may then also be the network access device of the device to be accessed.

Further, the device to be accessed may be connected to the network access device by connecting to the third network transmission device through the same path as the fourth network transmission device, thereby accessing the network.

As can be seen from the above embodiments, the present application may enable a device to be accessed to use a network transmission device in an access path of the device as a target transmission device by searching for an access path of the same type of network transmission device. By the method, the target network transmission equipment and the access path can be quickly found under the condition that the similar access equipment is denser, and the construction of an actual transmission link is guided. In addition, the access path of the network transmission equipment which is accessed to the network is a path which is built and configured relatively completely, and the path which is configured completely is multiplexed in the mode, so that the access efficiency of the equipment to be accessed is improved.

In a possible implementation manner, the network resource model further comprises node attribute information of each node, wherein the node attribute information of one node comprises a first connection list of the node and geographic position information of network transmission equipment represented by the node, and the first connection list indicates the network transmission equipment with a connection relation with the node; creating at least one target node in the network resource model according to at least one target network transmission device, comprising: for any target network transmission equipment, obtaining a first connection list of the target network transmission equipment according to the network transmission equipment with a connection relation with the target network transmission equipment; and adding the first connection list and the geographic position information of the target network transmission equipment serving as node attribute information of a target node representing the target network transmission equipment into the network resource model.

In one possible implementation manner, the creating at least one target node in the network resource model according to the at least one target network transmission device further includes: the target node is added to the first connection list of the new node and the target node is added to the first connection list of the network access point.

For example, there are two first network transmission apparatuses, network transmission apparatus a and network transmission apparatus B, as target network transmission apparatuses, of the apparatuses to be accessed. According to the target network transmission device, a target node A characterizing the network transmission device A is created in the network resource model, and a target node B characterizing the network transmission device B is created.

At this time, the node attribute information of the target node a includes the geographical location information of the network transmission device a and the first connection list, and the information indicated by the first connection list of the target node a is: the device to be accessed and the network access device, or the new node and the network access point.

The node attribute information of the target node B comprises geographical position information of the network transmission equipment B and a first connection list, and the information indicated by the first connection list of the target node B is equipment to be accessed and network access equipment or new nodes and network access points.

The information indicated by the first connection list of the new node is the network transmission device a and the network transmission device B, or the target node a and the target node B.

The first connection list of the network access point indicates the information network transmission device a and the network transmission device B, or the target node a and the target node B.

In a possible embodiment, the attribute information of the node in the network resource model further includes a node name, a device type, and a health degree, where the health degree of the node is determined according to the number of devices accessed by the network transmission device corresponding to the node.

In a possible implementation manner, the network resource model further comprises side attribute information of each side, the side attribute information of one side includes a second connection list of the side and the length and/or the health degree of the transmission link represented by the side, the second connection list indicates network transmission devices having connection relation with the side, and the health degree is determined according to the use time length of the transmission link. Establishing an edge connecting the target node with the new node and the network access point, comprising: and for any target transmission link connecting the device to be accessed and the target network transmission device or connecting the target network transmission device and the network access device, obtaining a second connection list of the target transmission link according to the network transmission device connected with the target transmission link. And adding the second connection list of the target transmission link, the length and/or the health degree of the target transmission link as side attribute information representing the target transmission link into the network resource model.

In a possible embodiment, the nodes in the network resource model all have unique identification IDs, and the IDs of the network transmission devices in the connection relationship are stored in the first connection list and the second connection list.

In one possible embodiment, the edges in the network resource model also have unique identifying IDs.

According to the embodiment, the target node is created, and meanwhile, the target node and the connected edges thereof are added, and the information of the new node of the target node is perfected. The new node is added into the network resource model through less information, but the information of the new node and the whole network resource model can be perfected gradually along with the creation of the target node. In addition, information can be provided for searching the target network transmission equipment for the new node which is established subsequently.

In one possible implementation manner, if the connection relationship between the target transmission device and the external network transmission device is queried in the information database, an external node corresponding to the fourth network transmission device is established, and an external edge between the external node and the target node is established. Obtaining a first connection list of the fourth network transmission equipment according to the network transmission equipment with a connection relation with the fourth network transmission equipment; and adding the first connection list and the geographic position information of the fourth network transmission equipment into the network resource model as node attribute information of a target node representing the fourth network transmission equipment. And obtaining a second connection list of the external transmission link according to the network transmission equipment connected with the external transmission link. And adding the second connection list of the external transmission link, the length and/or the health degree of the target transmission link as side attribute information representing the external transmission link into a network resource model.

Through the above embodiment, on the basis of establishing the target node, the network transmission device connected with the target transmission device is searched again and added as a node into the network resource model. In this way, with the establishment of new nodes, the number of nodes in the network resource model can be rapidly increased, and the network resource model can be systematically improved in a short time.

In one possible implementation, the network resource model further includes an information non-updated time period; the network resource model creation method further comprises the following steps: according to the information database, updating attribute information of network transmission equipment corresponding to the node with the information non-updated time length longer than the preset time length into a network resource model, and modifying the information non-updated time length of the node into a time length value representing current updating. And updating the attribute information of the transmission link corresponding to the side with the information non-updated time length longer than the preset time length into a network resource model, and modifying the information non-updated time length of the side into a time length value representing the current update.

The method and the device detect the update condition of the edge and node attribute information in the network resource model by increasing the parameter of the non-updated time length because the connection state of the connection link and the data transmission device can be changed. When the attribute information of the edge or the node in the network resource model is not updated for a long time, the attribute information is updated, so that the data in the network resource model is matched with the information in the information database.

In one possible implementation manner, the network resource model creation method further includes: at least two edges through which the new node is connected with the network access point are set as a connection path. And calculating the weight of the connecting path according to the shortest path algorithm, wherein the weight of the edge in the connecting path is obtained by taking the health degree and/or the length as the weight factor weighting. And comparing the weights of the connection paths to obtain an optimal path, and taking the optimal path as an access path of the new node.

For example, when a new node can connect to a network access point through multiple target nodes, the edge between the new node and each target access point, and the edge between each target access point and the network act as one connection path. And taking the health degree and the length of all the edges in the connecting path as weight factors, processing the weight factors, for example, weighting all the edges in the connecting path by using an objective weighting method, calculating an optimal path by using a shortest path algorithm, and taking the optimal path as an access path of a new node.

Specifically, when there are two target nodes, the two target access points are respectively denoted as a target access point M and a target access point N. The path of the new node to the network access point includes: new node-target access point M-network access point, and new node-target access point N-network access point.

And normalizing the health degree and the length of the weight factors of the four sides of the new node-target access point M, the target access point M-network access point, the new node-target access point N and the target access point N-network access point.

The health degree can be processed by the calculation of equation 1 as a forward index among the weight factors. The length is used as a negative index in the weight factor and is processed by the calculation of the formula 2.

In formula 1, x represents a value of the health degree of any one of the four sides, min (x) represents a value of the minimum health degree of the four sides, max (x) represents a value of the maximum health degree of the four sides, and x' represents a value of the processed health degree.

In equation 2, x represents a value of a length of any one of the four sides, min (x) represents a value of a minimum length of the four sides, max (x) represents a value of a maximum length of the four sides, and x' represents a value of a processed length.

Further, according to the processed health degree value and the length value, the standard deviation S1 of the health degree of the four sides and the standard deviation S2 of the length of the four sides are calculated. The standard deviation represents index variability of the corresponding weight factors, and the index variability represents the fluctuation condition of the difference of the internal values of the indexes.

And then, calculating the correlation coefficient between the health degree and the length of each side according to the processed health degree value and the length value, wherein the correlation coefficients of the four sides are respectively r1, r2, r3 and r4. The sum R of 1-R1, 1-R2, 1-R3 and 1-R4 is again calculated. R is used as index conflict, and represents the correlation among indexes of different weight factors.

Then, the information amount of the health degree is c1=s1×r, and the information amount of the length is c2=s2×r.

Therefore, the health degree is given a weight w1=c1/(c1+c2) as a weight factor, and the length is given a weight w2=c2/(c1+c2) as a weight factor.

Finally, the weight W of each side=the health of the side×w1+the length of the side×w2.

After the weight of each edge is known, according to Dijkstra algorithm, a new node is used as a starting point, and a network access point is used as an end point to start to find a path. And obtaining the connection path new node-target access point M-network access point and the weight thereof, and the connection path new node-target access point N-network access point and the weight thereof.

Among the two connection paths, the connection path with the smallest weight is the optimal path and can be used as the access path of the new node.

Of course, other methods may be used to weight edges or calculate shortest paths, such as weighting edges using coefficient of variation, and calculating shortest paths using the Floyd algorithm (insertion point method). In this embodiment, all edges in the connection path are weighted by using an objective weighting method, and the shortest path is calculated by using Dijkstra algorithm as an example, which does not limit the present application.

In one possible embodiment, the attributes of the edges in the network resource model further include the number of available connections, the number of lost connections, and the maximum number of connections. The maximum number of connections characterizes the maximum total number of nodes that the edge can carry as an access path. The lost connection number characterizes the number of nodes that the edge lost to be carried as an access path. The number of nodes remaining that can be used as bearers for the access path is characterized by the number of available connections.

According to the embodiment of the application, when a new service needs to be opened, a new node representing the equipment to be accessed is created in a network resource model according to the geographic position information of the equipment to be accessed. Thus, in the network resource model at this time, the new node corresponding to the device to be accessed is an isolated node with less information. In order to further expand the network resource model, a target network transmission device between the device to be accessed and the network access device of the device to be accessed is found in the information database, namely, the network transmission device for enabling the device to be accessed to be connected to the network access device is obtained, a target node corresponding to the target network transmission device and an edge for connecting the target node, a new node and the network access point are built in the network resource model, so that the purpose of expanding the network resource model is achieved, and the new node is not an isolated node any more. Therefore, the network resource model creation method provided by the application can gradually expand the network resource model along with the establishment of the new node, so that more information is provided for the establishment of the subsequent new node.

In addition, the network transmission equipment connected with the target network transmission equipment can be further expanded, and the network resource model is further expanded on the basis of the target node. In this way, the network resource model can be refined more quickly.

In addition, when a plurality of target nodes exist, the method can also calculate the weight of the access path passing through different target nodes by weighting edges among the new node, the target nodes and the network access point and then by a shortest path algorithm, so that an optimal path is selected as the access path from paths provided by the plurality of target nodes.
