Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
First introducing the network topology model of SDN, all-network resource is to divide with tree structure
Cloth.The superiors are a SC-controller node, i.e. top layer SC, can be distributed again under it
Multiple SC-controller.Multiple DC-controller is had under one SC--controller,
DC-controller is presented herein below network element, and SC-controller is not direct managed network element.This
Bright is exactly to be displayed by GIS map by the network topology model of SDN.
As it is shown in figure 1, SDNization GIS network topology model implementation method of the present invention, specifically
Comprise the steps:
S1. the client HttpClient by RESTful framework, sends a request to backstage, with
The request method of get or Post, to the data of background request topology resource.
S2., after backstage receives request, error code and the data of client request are returned, it is preferred that
Error code is resetful error code.
S3. whether the client error code that misdeems is more than 1000, if so, enters S5；If it is not, enter
Enter S4.
S4. prove to return error code unsuccessful, by the concrete type of error of interface prompt, terminate.
S5. think that backstage returns the data of topology resource correct, by request to data be converted to
The tree-like model object of self-defining topology (i.e. GISNcdBean object), as in figure 2 it is shown,
The attribute of this topological tree-like model object User Defined Resource, including node type (network element node and
Domain logic node), node ID, nodename (Name), network element node IP, node coordinate,
The radius of besieged circle (circular cover), father node object, word node set, port collection
Whether conjunction, annexation object set, object launch, object hierarchy.
S6. all of cache model data are removed, it is ensured that draw from the beginning of 0；Wherein, caching
Model data does not include the topological prototype data that restful please obtain, just for circular cover pair
As the caching with other data models is removed.
S7. draw topological tree-like model object node, and the circle caching current GIS map is covered
Cover material and the corresponding tree-like model object of topology, all nodes in GIS map, all use
The mode of Marker chained list stores.Concrete, described node includes network element node and domain logic
Node, all thinks into the circular covering in a GIS map by network element node with domain logic node
Thing object, the tree-like model object of the self-defining topology of recursive traversal, use top-down drafting
Mode draws each node.If running into domain logic node, first judge its deployed condition, logical
Cross whether condition adjudgement draws child node；If state is for launching, then draw child node；If state
For drawing in, the most do not draw child node, and change domain logic icon.If running into network element node,
Its network element attribute is arranged in the attribute of topological tree-like model object, GIS map often loads
One node, adds to nodal analysis method, circular cover object in a set synchronistic model.
As it is shown on figure 3, for gathering synchronistic model schematic diagram, use even numbers group to synchronize all of
Node, is the tree shape model that node is corresponding above, is node circle in GIS map below
Covering object, wherein, all of network element (Node) node and domain logic node (SC, DC)
It is regarded as a Marker (the covering object in GIS map).
S8. line is drawn, and needs to prepare the two ends node coordinate of line, by two end nodes
Coordinate could draw line.First the tree-like model object of the self-defining topology of recursive traversal, it is judged that
Node type, if domain logic node, then judge whether it launches, if launching, do not paint
Line processed；If not deployed, obtain all node set needed with its line
linkGISNcdBeanIds.Equally, to all node set got, need to judge its class
To not deployed domain logic node or network element node, type, only just supports that line is drawn, condition is all
If Man Zuing, by not deployed domain logic node or network element node in set, respectively with judgement
Domain logic draws line.Owing to, during traversal, all there is drafting in the two ends for line
Possibility, therefore can be by the way of setting up duplicate removal object model, it is to avoid repeat to draw identical
The line at two ends, the line of drafting represents the optical fiber connected.
Circular cover on S9.GIS map, expansion covering and resource including domain logic are looked into
Look for the covering behind location, by can be calculated the center of circle of circular cover, in conjunction with pre-setting
Radius, the information of needs can be clearly shown.For domain logic longitude in GIS map
And latitude, component topological model object when, calculate.Assuming that a circle
If covering region includes dry contact N1, N2 ... Nn, obtain the maximum in these nodes
Latitude Max_Latitude, maximum longitude Max_Longtitude, minimum latitude Min_Latitude
And minimum longitude Min_Longtitude, the abscissa in the center of circle is
(Max_Latitude+Min_Latitude)/2, (Max_Longtitude+Min_Longtitude)/
2。
Through above-mentioned steps, the network topology model of SDN can be shown in GIS map.
During use, if user clicks some circular cover (SC, DC) in GIS map,
Set synchronistic model is gone to get the topological tree shape model pair of correspondence by taking this Marker
As, now user needs operation to be to launch or draw in.
As shown in Figure 4, for expansion and the gathering flow chart of topological tree-like model object, specifically walk
Suddenly include:
A1. user clicks on the node in GIS map.
A2. judge the type of clicked on node, if network element node, enter A3；If logic
Domain node, enters A6.
A3. the association attributes of network element node, the network element node that caching is chosen are shown.
A4. judge whether the object tree of topological tree-like model object launches, if so, enter A5；
If it is not, terminate.
A5. inversely on object tree, it is highlighted the network element node chosen, terminates.
A6. the data syn-chronization of topological tree-like model object, the domain logic node that caching is chosen are processed.
A7. interface is repainted according to topological tree-like model object, including node and line.
A8. judge whether the object tree of the most topological tree-like model object launches, if so, enter
A10；If it is not, enter A9.
A9. have only on object tree, select this domain logic node, backstage real-time synchronization, terminate.
A10. synchronize and refresh this object tree.
A11. judge whether the domain logic state of this domain logic node in GIS map is launched, if so,
Enter A12；If it is not, enter A14.
A12. judge whether to comprise under this domain logic other domain logics, if so, enter A14；If
No, enter A13.
A13. on object tree, select all network elements under this domain logic, terminate.
A14. inversely on object tree, choose this domain logic node, terminate.
