Please refer to FIG. 1 , which is a schematic diagram of a system for dynamically providing and serializing a visual software network service according to a first embodiment of the present invention. The aforementioned system includes a client and a server. before The client system provides an external client for visualized drag and drop operation of the visual software network service dynamic supply and connection, and generates a visual drag operation instruction. The server end includes a service setting module, a service pool module, a software defined network module, a topological location calculation module, a service mapping module, and a message notification module. The service setting module is connected to the client to obtain a visual drag operation instruction. The service pool module provides one or multiple supply resources. The software-defined network module provides a software-defined network service. The topology location calculation module provides a node computing service for the resource; the service mapping module, the connection service setting module, the service pool module, the software definition network module, and the topology location calculation module; wherein the service mapping module is based The visual drag operation command searches for a physical or virtual network device from the service pool module, and configures a software-defined network module for dynamic serial installation, and configures a topology location calculation module to perform node position calculation. The message notification module is connected to the service setting module, and the service mapping module completes the installation and informs the client of the corresponding loading result.

The second embodiment of the present invention further provides a dynamic software network service dynamic supply and connection method. The foregoing method comprises the steps of: providing an external client to perform visualized drag operation of the visual software network service dynamic supply and concatenation, and generating a visual drag operation instruction. According to the visual drag operation command, the physical server module is used to find the physical or virtual network device, and the software is used to perform dynamic serial provisioning through the software definition network, and calculate the topological position of the supply node.

The dynamic software network service dynamic serial system and method of the present invention is based on displaying the association between network services by using a network topology manner, and automatically mapping the connection between the underlying virtual or physical network devices through a drag-and-drop network service manner. The system for dynamically connecting the visualized software network services is shown in FIG. 1. The server terminal 2 and the client terminal 3 are connected to the user 1 and the physical network device 4. line. The server terminal 2 includes a software module of the service setting module 21, the service mapping module 22, the service pool module 23, the software definition network module 24, the topology location calculation module 25, and the message notification module 26. The client 3 includes a software module such as a topology data module 31, a topology display module 32, a topology operation module 33, and a display policy module 34. The topology data module 31 includes an operation interface unit 311 and a data unit 312. The topology display module 32 includes a main body display unit 321, a layer display unit 322, a display setting unit 323, and an attribute synthesizing unit 324. The aforementioned topology operation module 33 includes a supply operation unit 331 and a serial operation unit 332.

The aforementioned client 2 can receive the message notified by the Web Socket and can judge the message to perform topology change. The topology data module 31 can support a plurality of topological operation display modules 32 and a plurality of topological operation modules 33 (FIG. 8). The foregoing topology data module 31 exists on the client 2, and its role can be written as an operation module by JavaScript, and provides operations such as adding and deleting repairs, searching for points or child nodes through keys, attribute synthesis or subject information query, etc. Display APIs such as policy module 34, access session/local storage operations, etc., and provide them to different display tools, such as D3.js or React.js (Figure 8). The data unit 312 stores only the original point (Vertex) and the original line (Edge), and can access the node (Node), the line (Link), the original point and the original line through the interface operation unit, and the content objects thereof are identical, and can be added or deleted. Repair the above API actions; The topology display module 32 obtains the two-column content of the point and the line, and performs data sorting through the display setting unit 323 and the attribute synthesizing unit 324. The display setting unit 323 provides the content of each attribute category, and the attribute synthesizing unit 324 displays the content according to the display. The strategy performs attribute synthesis.

The foregoing display policy module 34 is a topology content expression strategy, which can be customized by the user, such that the original point is an auxiliary point (does not affect the overall topology operation) or the original point or line is not suitable for display, but is used as data for data calculation. Points or lines, you can not put points and line arrays or The partial attribute content setting of this original point needs to override the setting provided by the display setting unit 323.

The main body display unit 312 obtains the object category and the layer display unit 322 to obtain an attribute category, and performs topology display. The user operation mode described above operates the loading operation unit 331 and the serial operation unit 332 by dragging. When the loading is performed by the loading operation unit 331, it is determined whether the service does not need the source node, otherwise the user needs to move the indicator to select the source node. In addition, if the supply is not related to the operating cost, the direct supply (delivery to the server end 2) is performed immediately after the drag and drop, and there is no dialogue behavior. In addition, if the installation relates to the operating cost, a virtual node (Virtual Node) and a virtual link (Virtual Link) are added to the topology data module 31, and the topology is redisplayed. The aforementioned virtual node (Virtual Node) and virtual link (Virtual Link) are immediately installed after the user decides to drag and drop (passed to the server terminal 2), and if the user gives up the drag and drop, the virtual node is deleted. The virtual link is connected to the topology data module 31 and the topology is redisplayed. The user needs to select the source node and the destination node in series, and drag and drop to connect to the server end 2, and there is no dialogue behavior.

The service setting module 21 can determine the setting requirement that the user drags the supply and the drag in series. The service mapping module 22 can obtain the available services for the service pool module 23 to supply. If the service does not include the source node, the selection process is based on the vertical deployment direction of the device. If the service includes the source node, the service is based on the overall topology tree. The most recent condition of the location of the virtual or physical device 4. The service mapping module 22 receives the virtual or physical device 4 where the source device and the destination node are located, and the dynamic connection is performed through the software-defined network module 24. After the drag-and-drop provisioning and dragging serial setting is completed, the service mapping module 22 performs overall topological position calculation through the topological position calculation module 25, and the calculation manner is relative to the topological position, the service level, the number of topology trees, and the number of services. Location calculation. Additional topological position After the calculation module 25 is completed, the notification module will use the Web Socket technology to notify the client 3 through the message notification module.

The user 1 browses the entire network topology structure through the topology display module 32 of the client 3, and uses the topology operation module 33 to issue an operation command to the server terminal 2. If the command is for the service, the operation mode is the drag mode. After receiving the supply instruction of the client 3, the server 2 transmits the message to the service setting module 21, and finds an available and profitable entity from the service pool module 23 through the service mapping module 22 according to the object of supply. The object service of the virtual network device is used for registration; if the command is connected in series, the operation mode is the same as the drag mode.

After receiving the service serial command of the client 3, the server 2 transmits the service to the service setting module 21, and finds and provides the two services from the service pool module 23 according to the object to be installed and through the service mapping module 22. A physical or virtual network device, and a network module 24 is defined by software to perform dynamic concatenation.

After being installed or connected in series, the topological position calculation module 25 performs a relative position calculation of the new node or line, and reflects back to the service mapping module, and finally returns the message to the client 3 by the message notification module 26 and reacts to Topology. When the topology data module 31 of the client 3 is initialized, the complete service topology data is obtained from the server. When the message notification module 26 notifies the new transaction, it updates to the topology data module 31, and the topology display module 32 Will reflect the latest topology information.

The detailed process of the dynamic serialization method of the visualized software network service of the present invention is shown in FIG. 2 to FIG. 7 , wherein FIG. 2 is a topology display module re-displaying step, and FIG. 3 is a server terminal 2 and a client terminal 3 Data visualization and transaction update process, FIG. 4 is a client 3 visual supply operation method, FIG. 5 is a client 3 visual serial operation step, FIG. 6 is a servo end 2 supply mapping step, and FIG. 7 is a servo terminal 2 The serial mapping process of the server, the above coverage includes Topology for the provisioning and concatenation of network services, the methods that occur on the client and the server.

First, in step 501, if the topology display module 32 detects that the node or the link data is changed, the topology is re-rendered, wherein the point is a visual network service and is mapped to the server 2 The service provided by the road virtual device is a series of visual network connection of two network services, and the serial connection mode is dynamically connected through the software defined network module 24 of the server 2 .

In step 502, the setting information of each attribute is obtained according to the attribute category of the point and the line to the display setting unit 323. In step 503, the attribute setting acquired from the display setting unit 323 and the attribute content carried by the point and the line itself are transmitted through the attribute synthesizing unit 324. The synthesis process is determined according to the display policy module 34. The step 504 is transmitted to the main body display unit 321 and the layer display unit 322 according to the item type and attribute content of the point and the line, and the complete topology is displayed after integration.

Step 601 is to determine whether the message delivery is transmitted by the Web Socket of the message notification module 26. If yes, the client only obtains part of the topology information for operation in step 602. If otherwise, the client obtains the complete information by step 603. The operation is performed, wherein when the user performs the operation by dragging the supply or the serial connection, the response result of the server 2 is transmitted through the Web Socket of the message notification module 26, and vice versa, the topology information is directly taken to the server 2. . Steps 602 and 603 will notify the topology data module 31 to perform the original point (Vertex) and the original data (Edge) data transposition through the operation interface unit 311, and operate the interface unit 311 to associate the source node and the destination node in the original line to The original point keeps the object index consistent and stores it in the data unit 312, where the original point is a network service and is mapped to the service provided by one of the network virtual devices, and the original line is the dynamic serial connection of the SDN networks of the two network services. The original point includes the above-mentioned point (Node), the difference is that the point is a visual material and is provided to the topology display module 32, and the relationship between the original line and the line is also the same. After the completion, the topology data module 31 of the step 605 is further transmitted through the operation interface unit 311. An array of Nodes and Links is additionally created or updated according to the display policy module 34 and stored in the data unit 312 with the content object metrics consistent with the original points and lines. Step 606: The topology data module 31 obtains the information of the point and the line through the operation interface unit, and then displays the information to the point and line attributes through the object state. Finally, the Render step is performed according to the method in step 5. The step 5 is as shown in FIG. After the topology display module detects that the point and the line data have changed, the Render topology is automatically performed, and the complete topology is synthesized and displayed according to the relationship between the object body and the attribute.

Step 701 is for the user to perform the drag supply through the feeding operation unit 331 of the topology operation module 33. Step 702 is to determine whether the dragged object needs to select the source node or not to select (only one optional or no optional case) If yes, proceed to step 703, the topology data module 31 adds a virtual node (Virtual Node) and a virtual link (Virtual Link) between the points through the operation interface unit 311, and the source node of the virtual line is associated with the selected one. The source node (if there is no source node, there is no virtual line), and is sent to step 5 for topology re-rendering, where the virtual point is the network service simulated by the client 3 itself, and the service cannot be mapped to the service provided by a certain device. The virtual line is a serial connection of the network simulated by the client 3 itself, and cannot be mapped to a network dynamic series. If the step 702 is no, the user needs to move the indicator to select the source node. Step 705: determining whether the user determines that the drag and drop is for loading. If the step is 707, the topology data module 31 deletes the virtual point and the line to the data unit through the operation interface unit 311, and finally performs the topology re-render by step 5. If yes, step 706 determines whether it is related to the operating cost, and then determines whether the supply is determined by step 708. If it is irrelevant to the operating cost, the dialog box is not required. If the installation is completed, step 707 is performed by the topology data module 31. The virtual point and line to data unit are modified through the operation interface unit 331.

In step 709, the setting of the server 2 is notified, and the process of step 901 is performed. After the server 2 receives the supply request from the client 3, the service setting module of step 902 will The service demand object is determined and the service mapping module 22 performs service registration. In step 903, the service mapping module 22 obtains the most profitable service and registers according to the source node to the service pool module of the supply requirement (this step is required). Based on the provisioning policy, the service mapping module 22 adds the registered service to the complete topology, and performs complete topology relative location generation through the topology location calculation module 25. Finally, the message is used to notify the module 25 via the step 905. Socket performs topology information change on client 3 (as shown in step 6 and Figure 3).

Step 801: The user selects the serial source node and the destination node through the serial operation unit 332 of the topology operation module 33, and after determining the connection, the step 802 notifies the service setting module 21 of the server to perform serial connection, and the step 803 is a topology data module. 31 will add a virtual line from the array of data taken out of the data unit 312 through the operation interface module 311, and then perform topology re-render by step 5.

Step 802 is to notify the serial connection of the server 2, and the process of step 1001 is performed. The server 2 receives the serial demand from the client 3, and the service setting module 21 determines the source node and the destination node of the serial demand, and The service mapping module 22 obtains the physical or virtual device that is actually supported by the two services. In step 1003, the service mapping module 22 transmits the physical or virtual network device provided in step 1002 to the SDN module for dynamic serial connection and serial connection. After the completion, step 1004, the service mapping module 22 performs complete topology relative position generation through the topology location calculation module 25. Finally, the step 1005 uses the Web Socket of the message notification module 26 to perform topology information change on the client 3 (such as steps). 6 and Figure 3).

Referring to FIG. 2 to FIG. 7 , the client 3 obtains the complete topology information from the server 2 and loads the data into the data unit 312 through the operation interface unit 311 of the topology data module 31 . It is one-to-many with the topology operation module 33 and the topology display module 32. The relationship, as shown in Figure 8, and the data array carried back by the client 3 is as shown in Equation 1.

Vertex set=[vertex ₁ , vertex ₂ ,...,vertex _n ] edge set=[edge ₁ ,edge ₂ ,...,edge _m ] edge={source vertex id,destination vertex id}

The operation interface unit 311 associates the source and destination information of the original content to the original point (Vertex) as follows: edge={vertex ₅ , vertex ₃ }

Vertex set=[vertex ₁ , vertex ₂ ,...,vertex _n

After the association is established, the operation interface unit 311 additionally establishes a Node and a line array according to the display policy module 34, and the content object objects are consistent with the original points and lines, as shown in Equation 2.

Vertex set=[vertex ₁ , vertex ₂ ,...,vertex _n ] edge set=[ edge ₁ , edge ₂ ,..., edge _m ] node set=[node ₁ ,node ₂ ,...,node _k ] link set=[ link ₁ , link ₂ ,..., link _z ] node Vertex set ink Edge set lk=1,2,...,n z =1,2,..., m formula 2

The display policy module 34 is a topology content expression strategy, such that the original point is an auxiliary point (does not affect the overall topology use operation) or the original point or line is not suitable for display, but is used as a data point or line for data calculation, or not Put in the point and line array. The topology display module 32 loads the point and line array through the operation interface unit 311, and determines the state of the object to add information to the point and line genus. Sex. If the object is a genuine creature (not supplied by a later user), the native attribute can be added. When the topology display module 32 detects that the point and the line data have changed, the object is re-rendered, and the main body display unit 321 forms an object base type according to the object state, and the layer display unit 322 stacks the object complete type according to the attribute ( Figure 9).

The user 1 is dragged and supplied through the loading operation unit 331 of the topology operation module 33. The service area and the reaction area are as shown in FIG. 10, and when the user selects a service from the service area and drags it to the reaction area, the topology judges. Do you need to choose a source node? Otherwise, as shown in FIG. 11, if it is, it is as shown in FIG. If the source node is determined or the source node is not needed, and dragged to the current reaction zone, the topology data module 31 adds a virtual node (Virtual Node) and a virtual link between the array of points and lines, and performs a topology re-rendering. After the user determines that the drag and drop, if it is not related to operating costs, such as increasing the private domain (Private Subnet), it will be sent directly to the server 2 for installation, no customer dialog box, if it is related to operating costs such as virtual machine (Virtual Machine ) The dialog box needs to be determined to be installed. If the user gives up the installation, the virtual point and line are deleted, and the virtual point and line are modified after the installation is completed.

The user performs the drag connection through the serial operation unit 332 of the topology operation module 33, as shown in FIG. 13, obtains the source node and the destination node, and notifies the service setting module 21 of the server terminal 2 to perform serial connection, and the topology data module 31 The virtual line is added to the line array of the existing data unit 312 through the operation interface module 311.

The server 2 receives the supply request from the client 3, and the service setting module 21 determines the supply request object and performs service registration through the service mapping module 22, and the service mapping module 22 and the service pool module 23 The relationship is shown in Figure 14 and Equation 3, and all the services available on the virtual and physical network device 4 are placed in the service pool.

Service set=[service ₁ ,service ₂ ,...,service _i ] device set=[device ₁ ,device ₂ ,...,device _j ] device service set=[service ₁ ,service ₂ ,...,service _h ] device service set Service set formula 3

The service mapping module 22 obtains the service from the service pool module 23 according to the context of the object to be loaded. If there is no source node, the service is selected according to the vertical deployment mode of the device. As shown in FIG. 15, the unused service is obtained. registered. If the installation object includes the source node, as shown in FIG. 16, the overall topology tree is selected to have the latest condition of the location of the device where the service is located. After the installation is completed, the topology calculation module 25 is used to generate the complete topology relative position, as shown in the figure. 17, each node has an (x, y) coordinate parameter, which determines the location of y according to the service level of the network, and the network service level is set by the system, such as the Internet service. Level 0, private domain is level 1, virtual machine is level 2, through the top to bottom from small to large, and the distance between the levels is determined according to a constant, that is, the position of y can be generated; each topology is regarded as A tree whose tree-to-tree spacing (Tree Interval) is used to determine the position of x is a constant. Each topology takes a service as a central point. The central point is used to determine the relative location of services across the entire topology. If the service is different from the service, the service is spread out from the nearest service. The diffusion method uses the Service Number to judge the angle of the line opening. If the service level is the same between the service and the service, it is not necessary to calculate the opening angle of the line, and the horizontal or vertical connection is directly connected. Different trees are considered to be the same tree in series. Finally, the client will be notified and topologically changed through the Web Socket technology of the message notification module 26.

The server 2 receives the serial demand from the client 3, and the service setting module 21 judges The source node and the destination node of the serial connection requirement are obtained through the service mapping module 22 to obtain the physical or virtual network device supported by the bottom layer, and then dynamically connected through the software definition network module 24 as shown in FIG. 18, after the serial connection is completed, the utilization is performed.
