The basis of design.Excessively advanced prediction can increase system Construction input, waste network bandwidth；And overly conservative estimation meeting
Network capacity is caused to turn into the bottleneck of whole communication of power system.Therefore, construct rational bandwidth prediction method and just can guarantee that electricity
Power communication network planning, design and the smooth development built.Because power telecom network is special service in power generation, the net of operation
The index request such as network, its reliability, bandwidth can be some higher compared to public telecommunication network, and bandwidth prediction method also different from
Public network；Elastic coefficient method application is ripe, can the convenient primary demand for meeting communication.And the method for queueing theory can more embody business and move
The advantage of step response.
Current bandwidth prediction device is mostly the process that bandwidth estimation is provided from the convergence characteristic of node or section, but
It is that bandwidth prediction is the overall process based on network structure.
The content of the invention
It is an object of the present invention in view of the above-mentioned problems, a kind of power telecom network auto-bandwidth prediction meanss are proposed, with reality
Now improve the efficiency and accuracy of predicting bandwidth flow.
To achieve the above object, the technical solution adopted by the present invention is：A kind of power telecom network auto-bandwidth prediction meanss,
Mainly include：
Input pretreatment unit, data input cell, main control unit and display unit are sequentially connected with,
The input pretreatment unit, for gathering the different type node typical case of itself in power telecom network topological structure
Business and flow, and collection result is sent to data input cell processing；
The data input cell, for being the sparse matrix of adjacency matrix by power telecom network network representation, and calculate
Initial flow corresponding to node and path number, result of calculation is sent to main control unit processing；
The main control unit, for judge each node in power telecom network whether be now network endpoint node, such as
Fruit is endpoint node, will be converged on the path of the flow superior of the node and node, while by this node from the sparse of network
Deleted in matrix, update flow on node flow and path, if still having member in the sparse matrix of network after the completion of often wheel judges
Element, then returned data input block, if the sparse matrix of network is sky, into display unit；
The display unit, show broadband prediction result.
Further, the active cell is DSP Processor.
Further, the display unit is specially display screen.
Further, the node includes overall as the looped network of a node.
The power telecom network auto-bandwidth prediction meanss of various embodiments of the present invention, input pretreatment unit, data input list
Member, main control unit and display unit are sequentially connected with, and the mutually coordinated processing of unit, finally realize the remittance according to specific network
Poly- model, all nodes of network and the auto-bandwidth in path are predicted, substantially increase staff and carry out predicting bandwidth flow
Efficiency and accuracy, instruct staff to find out the bottleneck portion of current network capacity conscientiously, so as to guide the accurate of investment
Launch.
Other features and advantages of the present invention will be illustrated in the following description, also, partly becomes from specification
Obtain it is clear that or being understood by implementing the present invention.
Below by drawings and examples, technical scheme is described in further detail.
Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and a part for constitution instruction, the reality with the present invention
Apply example to be used to explain the present invention together, be not construed as limiting the invention.In the accompanying drawings：
Fig. 1 is the structure composition figure of power telecom network auto-bandwidth prediction meanss；
Fig. 2 is somewhere city power telecom network topological diagram；
Fig. 3 is power telecom network bulk flow prediction case figure.
Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Including input pretreatment unit, data input cell, main control unit and display unit.According to the convergence of specific network
Model, realize to all nodes of network and the prediction of the auto-bandwidth in path, it is pre- to substantially increase staff's progress bandwidth traffic
The efficiency and accuracy of survey, instruct staff to find out the bottleneck portion of current network capacity conscientiously, so as to guide the essence of investment
Standard is launched.
The present invention is a kind of power telecom network auto-bandwidth prediction meanss, including input pretreatment unit, data input list
Member, main control unit and display unit, data input cell are connected with input pretreatment unit, and it is defeated that main control unit connects data respectively
Enter unit connection and display unit.Input the different type node allusion quotation of itself in pretreatment unit collection power telecom network topological diagram
Type business and flow, the own service flow of the node on looped network is added, depending on a looped network generally node.Data input list
Member represents power telecom network network in the form of the sparse matrix of adjacency matrix, and calculates corresponding to egress and path number just
Beginning flow.Main control unit is DSP Processor.Display unit is the display screen being arranged in auto-bandwidth prediction meanss.
Wherein, main control unit includes：
It is the endpoint node of now network to judge each node in power telecom network successively, if being not pointed towards the section
The side of point, then this node is the endpoint node of network.If endpoint node, by the path of the flow superior of the node and section
Converged on point, while this node is deleted from the sparse matrix of network, update flow on node flow and path.If often take turns
Still there is element after the completion of judgement in the sparse matrix of network, then returned data input block, if the sparse matrix of network is sky,
Then enter display unit.
The present embodiment is by taking somewhere city power telecom network as an example, as shown in Figure 2.The different type node online to power communication
The business of itself carrying is analyzed, while carries out Prediction of Bandwidth Requirement, is then estimated according to this paper flow estimation method
Bandwidth traffic on network on all nodes and path, the present situation of districts and cities' power telecom network is finally contrasted, analyse whether to meet
Demand is, it is necessary to be further optimized lifting.
After obtaining the bandwidth traffic converged on all nodes, to the totality on all nodes in addition to power supply and user's change
Flow prediction situation is counted, and statistical result is as shown in Figure 3.The ratio between predicted flow rate and actual optical transmission device capacity are less than
20% website is 39, and these websites are mostly end website.The ratio between predicted flow rate and actual optical transmission device capacity are more than
80% and the website less than 100% be 4, these websites are all middle aggregation nodes, and are not the nodes on looped network, are existed
The necessity of certain optimization and upgrading.The website that predicted flow rate exceedes place capacity has 24, and these websites are mostly the station on looped network
Point.This illustrates the necessity of optimization and upgrading be present according to the typical bandwidth forecast model of company, these websites.
It can be seen that according to the coalescence model of specific network, the present invention is realized to all nodes of network and the auto-bandwidth in path
Prediction, efficiency and accuracy that staff carries out predicting bandwidth flow are substantially increased, instructs staff to find out mesh conscientiously
The bottleneck portion of preceding network capacity, so as to guide the accurate dispensing of investment.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
