Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
Fig. 1 shows a flowchart of a network base resource planning method provided by an embodiment of the present invention, which is performed by a network base resource planning device. The network base resource planning device may be a computer device, a terminal device, a system, a server, a device of a distributed architecture, etc. The network basic resource planning method of the embodiment of the invention is used for resource planning of the infrastructure of the transmission network, and the transmission network comprises a convergence machine room, a primary optical communication, a secondary optical communication, service points and transmission lines between the service points, such as pipelines, rods, optical cables and other infrastructures. Each converging machine room is connected with a plurality of primary optical intersections, each primary optical intersection is connected with a plurality of secondary optical intersections, and each secondary optical intersection is connected with a plurality of service points. The convergence machine room is a service convergence point, and the convergence machine room comprises an OLT (optical line terminal) and an optical line terminal. The first-level light exchange is also called as trunk light exchange (trunk optical cable cross connecting box), and the second-level light exchange is also called as wiring light exchange, cell light exchange and building light exchange. As shown in fig. 1, the method comprises the steps of:
Step 110: and respectively acquiring service distribution data and geographic environment data of the service points.
Wherein the service distribution data of the service points comprises information of a plurality of service points needing to cover the network. Before the service point information is acquired, a target planning area is determined, and service distribution data of service points which need to be covered are searched in the target planning area by means of regularization and the like through open API interfaces such as Gordon, drip, hundred degrees and the like and webpage public information. The information of the service point comprises information such as the position of the service point, the service demand, the service point type and the like, and if the service point is a residential district, the longitude and latitude of the district, the number of the living houses of the district, the price of the district, the type of the district and the like are obtained.
In the embodiment of the invention, the geographic environment data of the target planning area is also collected, and the road information and other basic geographic environment data information of the target planning area can be determined through open API interfaces such as Golde, drip, mobye, hundred degrees and the like and the geographic environment data prestored in the database. The road information includes longitude and latitude information, material information and the like of the road.
Step 120: and determining the position of the secondary optical communication according to the service distribution data.
In the embodiment of the invention, after service distribution data of service points are obtained, the service distribution data are subjected to standardized processing, and the service distribution data are processed into service standard data according to preset planning key indexes; the service standard data comprises a plurality of standard dimension information of the service point. The preset planning key indexes comprise indexes such as service point types, service point positions, service point weights and the like. The service point weight may be calculated according to the type of the service point, the number of users of the service point, the room price of the service point, and other information weights. If the weight of the enterprise office building is higher than the weight of the residential district, for the residential district, the type weight of the residential district, the weight of the number of the living units of the residential district and the average price weight of the residential district can be determined according to a preset weight setting rule to calculate the weight of the residential district. The preset planning key index and the preset weight setting rule can be set according to specific scenes, and can also be determined according to historical experience values, and the embodiment of the invention is not particularly limited. Accordingly, the service standard data includes a plurality of standard dimension information of the service point, and the plurality of standard dimension information includes type information, position information, weight information and the like of the service point.
Because one secondary light intersection is directly connected with a plurality of service points in a star-shaped manner, after a plurality of standard dimension information of the service points are determined, clustering can be carried out by adopting a clustering algorithm, and the positions of the secondary light intersections are obtained. Specifically, the density distribution of the service points can be determined by combining the information such as the type information, the position information, the weight information and the like of the service points in a spatial clustering DBSCAN mode, so that the position of the secondary optical cross construction is determined. And aggregating the service points with similar types, similar positions and similar weights to form a cluster, determining the center of the cluster, and determining the center of the cluster as the optimal position of the secondary light intersection.
In addition, the positions of the service points can be clustered through a k-mean clustering algorithm to obtain clusters with similar distances, the type and weight information of the service points are combined to determine a target weight value, and the positions of the secondary light exchanges are determined according to the clusters and the target weight value. For example, if the center of the cluster is the first longitude and latitude, the position of the secondary light intersection is the first longitude and latitude, which is the target weight value. Wherein the representation of the target weight value may be a multidimensional vector. Specifically, the multidimensional vector is determined according to the statistical data of the historical existing network, and the multidimensional vector comprises the dimensions of the number of optical cables, the broken line coefficient, the safety coefficient and the like of different scenes. In the historical network planning of the optical cable quantity, the optical cable quantity planned by the optical cable quantity is used for a certain service type; the broken line coefficient represents the wiring mode under the service type; the security coefficient characterizes the security requirement corresponding to the service type, for example, in the statistical history network planning, the requirements of the optical cable planning of the government building, school, enterprise or rural area and the like on the quantity, the broken line coefficient, the security coefficient and the like are different for different service requirements.
Step 130: and respectively determining the position of the primary optical cross, the position of the access machine room, the position of the convergence machine room and the position of the core machine room according to the service distribution data, the position of the secondary optical cross and the geographic environment data.
Wherein, for a network resource planning of a certain local area, it comprises: primary optical traffic, secondary optical traffic, service points, access machine room, convergence machine room, and core machine room. The convergence machine room plays a role in the network and is responsible for connecting the local service nodes to backbone nodes and converging and guiding the services to corresponding service nodes through physical and logical networks. The network of the local area is connected with the network of other areas through the backbone layer optical cable by the convergence machine room, and finally is connected with the core machine room. The core machine room generally refers to equipment for realizing the work of centralized processing, storage, transmission and extraction, exchange, management and the like of information in one physical space.
After the geographical environment data is acquired, the geographical environment data needs to be standardized, the geographical environment data includes road distribution data, and each piece of road information in the road distribution data is a string of longitude and latitude data. After the geographic environment data is standardized, a first undirected graph G1 (q, e) can be generated according to the position of the secondary light intersection, the position of the service point and the geographic environment data after the standardized processing, wherein q represents a node corresponding to the secondary light intersection, e represents a path possibly existing on the basis of the geographic environment, wherein the secondary light intersection is between a plurality of corresponding service points. In the embodiment of the invention, the geographic environment data also comprises other geographic data of the area to be planned, including river data, mountain data, railway data and the like, so that when the first undirected graph is generated according to the position of the secondary light intersection, the position of the service point and the geographic environment data after the standardized processing, factors of the river data, the mountain data and the railway data in the geographic environment data are also considered, and the path in the undirected graph bypasses the area with mountain, river or railway. Because the primary light intersection or the access machine room is distributed along the road, after the position of the secondary light intersection is determined, the position of the primary light intersection or the position of the access machine room can be determined by combining the position of the secondary light intersection and road distribution data. In one embodiment of the invention, the density distribution of the secondary light intersection can be determined according to the position of the secondary light intersection; determining from traffic distribution data, said density distribution and said road distribution data
The first-level light exchange position or the position accessed into the machine room. And determining the density distribution of the secondary light intersection according to the position of the secondary light intersection, specifically grouping the secondary light intersection by adopting a density distribution function, wherein the secondary light intersections belonging to the same group correspond to the same primary light intersection or are connected into a machine room. First order light intersection set v= { V1, V2, V3 … … }; wherein Vn represents primary optical cross or access to a machine room, and the secondary optical cross belongs to the set v1= { q1, q2, q3 … … }, wherein q n represents secondary optical cross. After the secondary light intersection set is determined, the optimal primary light intersection position or the position of accessing the machine room is determined by combining road distribution data. The secondary light intersection positions can be clustered based on a density distribution function by combining road distribution data to obtain a secondary light intersection set, such as a DENCLUE algorithm or a DBSCAN algorithm. In another embodiment of the invention, the position of the first-level light intersection or the position of the access machine room is determined by combining the k-means with road distribution data.
The convergence machine room is determined from a plurality of primary optical buses or access machine rooms according to service distribution data. For a transmission network, the convergence machine room is connected with a plurality of primary optical cross or access machine rooms through a ring structure or tree structure, as shown in fig. 2. After the primary light exchange or the access machine room is determined, determining the convergence machine room from the primary light exchange or the access machine room according to a preset machine room determination algorithm. The preset machine room determining algorithm can be one or more of a minimum jump method, a k-shell algorithm, an eccentricity algorithm, a betweenness center algorithm, a PageRank algorithm and the like. Specifically, the minimum jump method refers to determining which service points need to arrive at the convergence machine room fastest according to the multidimensional information of the service points, and determining the position of the convergence machine room according to the service point information of the convergence machine room which needs to arrive at the convergence machine room fastest. That is, the service point that needs to reach the convergence fabric room at the fastest speed may be determined by the type information, the weight information, and the like of the service point. The embodiment of the invention is not particularly limited to the service points which need to reach the convergence machine room at the highest speed, and the person skilled in the art can perform corresponding setting according to specific scenes. Specifically, the importance of the first-order optical cross or access machine room can be determined through a k-shell algorithm, an eccentricity ratio algorithm, a bettery center algorithm, a PageRank algorithm and other algorithms, the first-order optical cross or access machine room is ordered according to the importance of the first-order optical cross, and the most important first-order optical cross or access machine room obtained through ordering is determined as a convergence machine room.
The method for calculating the influence of the nodes in the network by the k-shell algorithm is provided. The nodes with all degrees of 1 are found out first and deleted. And then continuing searching for the node with the degree of 1 in the rest nodes, and deleting. Until there is no node with degree 1 in the network, the value of kshell of the node with degree 1 deleted before is assigned to 1, i.e., ks=1. The node with a degree of 2 is then looked up in the same way and ks=2 is assigned. This is followed by a degree of 3 and a degree of 4 … … and assigning ks=3 and ks=4 … …, respectively, until all nodes in the network have k-shell values. The higher the KS value, the greater the influence. The PageRank algorithm is a Google ordering algorithm, and assigns a weight to each target node, wherein the ordering with a large weight is forward, and the ordering with a small weight is backward. The more important it is to determine which primary light cross is referenced. Specifically, the number of references can be determined by the number of paths carried by the primary optical transport and the weight of the service point.
After the converged machine room is determined, the position of the core machine room can be determined according to the service distribution data, the positions of the converged machine rooms in all areas and the geographic environment data. The process of determining the position of the core machine room according to the service distribution data, the position of the convergence machine room in each area and the geographical environment data is consistent with the manner of determining the convergence machine room, and is not repeated here.
Step 140: and generating a target undirected graph according to the geographic environment data, the position of the secondary light intersection, the position of the primary light intersection, the position of the access machine room, the position of the convergence machine room and the position of the core machine room. .
Generating a target undirected graph G= (V, e) according to geographic environment data, the position of the secondary light intersection, the position of the primary light intersection, the position of the access machine room, the position of the convergence machine room and the position of the core machine room, wherein V represents nodes of the target undirected graph, and the nodes of the target undirected graph represent the position of the primary light intersection, the position of the access machine room, the position of the secondary light intersection, the position of the convergence machine room and the position of the core machine room; e represents the side of the target undirected graph, which is a possible path between each node of the primary optical cross, the access machine room, the secondary optical cross and the convergence machine room or a possible path between the convergence machine rooms and between the convergence machine room and the core machine room on the basis of the geographic environment. Fig. 3 shows a schematic diagram of a target undirected graph of a network-based resource planning method according to an embodiment of the present invention. The figure shows the structure of a target undirected graph of the ring cable, where the graph is the structure of the ring cable, and all possible paths are generated in the topology graph when determining the target line. The dashed frame part only shows the schematic diagrams of the converging machine rooms and the core machine rooms of other areas to be planned, and each converging machine room and the corresponding primary optical fiber, the secondary optical fiber of the access machine room, the service nodes and the like form an annular optical cable in the corresponding area.
Step 150: and determining a target line according to the target undirected graph.
In the embodiment of the invention, after the service point, the secondary optical cross, the primary optical cross, the access machine room, the convergence machine room, the core machine room and the corresponding relation are determined, the final target lines among the service point, the secondary optical cross, the primary optical cross, the access machine room, the convergence machine room, the core machine room and the corresponding relation are also required to be determined. In the embodiment of the invention, the connection relation of the primary optical fiber intersection and convergence machine room comprises an annular optical cable and a tree-shaped optical cable. As shown in fig. 2, a tree structure and a ring structure schematic diagram of a transmission network according to an embodiment of the present invention are shown. Wherein, the left graph in fig. 2 is a ring-shaped optical cable, and the right graph is a tree-shaped optical cable. The routing of the annular optical cable comprises IP RAN/OTN/SPN/PTN/SDH optical cable routing; the routing of the tree-like optical cable includes PON network optical cable routing. The route refers to a line between the nodes.
For the annular optical cable, in the embodiment of the invention, the optical cable route of the annular optical cable is determined according to the target undirected graph, and specifically, a Hamiltonian loop between the optical cross of which the converging machine room is a node and the lower hanging wireless machine room is searched; the light exchange of the lower hanging wireless machine room comprises a first-level light exchange of the lower hanging wireless machine room and a second-level light exchange of the lower hanging wireless machine room; the routing of the hamiltonian loop is determined as the cable routing of the ring cable. The cable route is determined to be an IP RAN/OTN/SPN/PTN/SDH cable route. A hamiltonian graph (hamiltonian graph, hamiltonian graph, or a movable graph) is an undirected graph, from a specified starting point to a specified ending point, passing all other nodes en route and only once. Referring to a graph containing Hamiltonian loops, the closed Hamiltonian path is referred to as a Hamiltonian loop (Hamiltonian cycle), and the path containing all vertices in the graph is referred to as a Hamiltonian path (Hamiltonian path). For the ring cable of fig. 3, the routing of the ring cable is determined by the specific algorithm described above, as indicated by the bolded lines in the figure.
And for the tree-shaped optical cable, determining the optical cable route of the annular optical cable according to the target undirected graph. In the embodiment of the invention, the aggregation machine room is taken as a root, and the minimum spanning tree is searched for to determine that the route of the minimum spanning tree is the optical cable route of the tree-shaped optical cable, and the route of the minimum spanning tree is the optical cable route of the PON network. The minimum spanning tree refers to a spanning tree of a connected graph with n nodes, which is a very small connected graph of the original graph and contains all n nodes in the original graph, and has the least edges for keeping the graph connected. The minimum spanning tree may be found using kruskal algorithm or prim algorithm.
Because the services carried by different optical cable routes are different, the annular optical cable and the tree-shaped optical cable can exist for one service point at the same time, and therefore, after the routes of the annular optical cable and the tree-shaped optical cable are determined, the routes can be overlapped to obtain a target line. Because the routes of the annular optical cable and the tree-shaped optical cable are all in a logical connection relationship, the optical cable can be a line in an actual scene, and therefore, the target line can be generated by combining geographic environment data superposition.
Step 160: and generating a target planning scheme according to the service point, the position of the secondary optical cross, the position of the primary optical cross, the position of the access machine room, the position of the convergence machine room, the position of the core machine room and the target line.
The positions of the service points, the second-level optical cross positions, the first-level optical cross positions, the positions of the access rooms, the positions of the convergence rooms, the positions of the core rooms and the target lines among the core rooms are determined through the steps 110-150. Thus, a target planning scheme may be generated based on the locations of the respective nodes and the target routes.
In the embodiment of the invention, when the target planning scheme is generated, the safety factors in the geographic environment data are also required to be considered, and the executable standardized target planning scheme is finally generated.
According to the embodiment of the invention, the basic resource planning is carried out based on service distribution and geographic environment, the secondary light exchange is determined based on service point data, the primary light exchange is further determined according to a density distribution function, the determined points are abstracted into the target undirected graph based on the geographic environment, and the target line is determined, so that the target planning scheme is finally obtained, the resource planning is standardized, the accuracy is high, and the planned network resources and the service can be optimally matched. Furthermore, by the mode, planning can be automatically operated, and efficiency is improved.
In addition, the collected service distribution data of the service points are converted into standard service data, so that the data standards are unified, and the indexes are easier to quantify.
