Description
Technical field
The present invention relates to the drawing algorithm field, particularly relate to a kind of multiple drafting mode of virtual machine topological diagram.
Background technology
The upsurge of cloud computing have swepts the globe, needs that should the development of each major company, and the development trend of cloud computing can not fail in a short time.The structure that in browser, represents the virtual machine network topology, applet, flex, vml, sva and javascript etc. can realize.
Technically, it is not crucial adopting which kind of technology, and key is the algorithm of drawing topological graph; Generally be the coordinate of calculating the node that will draw on method for drafting, the position of node on drawing board of having good positioning judges whether the position has had node, without then drawing, has then to move on every side and draws without the place of node.
But this kind drafting mode is generally comparatively single, has not considered multiple situation.The present invention makes up first model again according to the modeling rendering topological diagram, and is simple and clear, and this kind drafting mode does not have substantially.
Summary of the invention
Technical matters to be solved by this invention is the implementation method that a kind of virtual machine topological diagram of design is drawn, draw to solve the topology that realizes under the prior art for the resources of virtual machine relation, the design's method can be drawn out the topological relation of the various resources of virtual machine in browser, can mutual modification check relation in real time, have preferably simple and clear application.
For achieving the above object, the invention provides the implementation method that a kind of virtual machine topological diagram is drawn, comprise that the topological diagram of one-to-many is drawn, the topological diagram of multi-to-multi is drawn.The topology of multi-to-multi is drawn can be divided into again the drafting of simple many-to-many relationship topology and the drafting of complicated many-to-many relationship topology.
Described one-to-many topological diagram is drawn, be used for: it is the situation of one-to-many that resources of virtual machine closes, be the relation of one-to-many such as the relation of main frame and virtual machine, under this relation, the mode that adopts is the size that calculates the browser drawing board, and according to the size of browser, the used pattern of situation of determining this one-to-many is class circle model, calculate delegation and can place what classes circle model, surpassing namely increases delegation; The radius size that compute classes is round, but make on the node mean allocation and circle that will be positioned on the circle, and it is each class circle model of separating distance that 100 pixels are set.
Described multi-to-multi topological diagram is drawn, and is used for: it is the situation of multi-to-multi that resources of virtual machine closes, such as network and virtual machine, or main frame and network.In the relation such as main frame and network multi-to-multi in this, because the number of main frame and network is less, adopt the class circular pattern, also can solve, but compare the rectangle like mode, seem complicated.The model of employing rectangle like can be more clear, the rectangle like pattern is, for example in main frame and cyberrelationship, calculate first the size of browser drawing board, read host information, the main frame of related network is arranged by ascending order, calculate position, the left and right sides, about main frame is positioned over, network is placed in the middle of the rectangle like model, then connects their relation.For the relation of the multi-to-multi of complexity, still adopt class circle model, Set Font size 12, determine first the size of circle, to contact maximum mode 12 as initial initial point, coordinate (0,0) is organized in together related, be drawn as monoblock, the computed altitude width does not have the related above step that repeats, and will all be divided into polylith and calculate height overall beam overall and minute other home position, calculate node separately, then draw.
The present invention also provides a kind of method of drawing the various resources relationships of virtual machine, and operation topological diagram that can be mutual, comprising:
On binding alternative events and the topological diagram, the user can understand according to topological diagram the details of virtual machine.If the user has enough authorities, the relation of change part topological diagram that just can be manual, the relation of change can operate on virtual machine really;
The user provides the relationship type of required resources of virtual machine, and server is selected rendering algorithm according to relationship type, and selecting automatically can the more convenient mode of concisely drawing out topological diagram.One-to-many adopts class circle model, and simple multi-to-multi adopts the rectangle like model, and complicated many-to-many relationship adopts class circle model; The binding Event and Method is that topological diagram can a dynamic interaction virtual machine information.
Can be found out by such scheme, in browser, draw out among the present invention can be mutual topological diagram, can be cross-platform, move at many total browsers, can solve the browser-safe problem; In the time of drawing topological graph, define first the model of the topological diagram that will draw, then calculate coordinate according to model, can make things convenient for simple and clear drafting, can solve the complicated loaded down with trivial details operation of drawing topological graph.In some alternative events of topological diagram binding, can solve dynamic operation and check the resources of virtual machine details.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do simple the introduction to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 draws schematic flow sheet in the embodiment of the invention one;
Fig. 2 is that many-to-many relationship is drawn schematic diagram in the embodiment of the invention one.
Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
