Configuration information after device is created node elements by corresponding interface is synchronized to two-layer virtual private network and L 3 virtual is special
With in the network equipment of the corresponding controller of network and each network of controller connection, which can be net
Network edge router, customer terminal equipment (referred to as cpe device), core router etc.;After synchronizing information, between each network
The network equipment is provided with direct communication connection relationship, and then obtains above-mentioned two two-layer virtual private network and three layers of void
The combinational network of quasi- dedicated network.
The process of above-mentioned node elements creation is referred to as node elements instantiation process, it is understood that for according to each
The process of the configuration information distribution Internet resources of a node elements.
In continuing to refer to figure 1, after combinational network is established, the network equipment (such as edge road of two two-layer virtual private networks
By device) it is communicated to connect respectively with the network equipment of three-layer virtual special network (such as edge router), to realize two two layers
The fusion of Virtual Private Network and a three-layer virtual special network, i.e., above-mentioned two-layer virtual private network and L 3 virtual are dedicated
The combinational network of network.
In general, two-layer virtual private network and three-layer virtual special network need to create in same VLAN (Virtual
Local Area Network, virtual LAN) under be just able to achieve network interworking.Therefore, the wound of existing Virtual Private Network
It during building, is influenced by the routing mode difference of two-layer virtual private network and three-layer virtual special network, accesses three layers of void
The two-layer virtual private network equipment of quasi- dedicated network needs to obtain virtual LAN belonging to three-layer virtual special network in advance
VLAN ID, and the VLAN ID need three-layer virtual special network create after the completion of could obtain;Therefore, above-mentioned in order to realize
The combinational network of two-layer virtual private network and three-layer virtual special network, needs first to create three-layer virtual special network, then from

Creation process is difficult to automate realization.
Based on the above issues, disclosure embodiment provides the creation method, device and server of Virtual Private Network.
Disclosure embodiment provides a kind of creation method of Virtual Private Network first;This method is applied to operation NFV
The equipment of composer.The NFV composer is referred to as NFVO (Network Function Virtualization
Orchestrator, network function virtualize composer);User in the process can using NFV composer planned network topology template
With use TOSCA software, naturally it is also possible to using other software carry out layout, the present embodiment to NVF layout implement body how into
Row network topology template layout is simultaneously not limited.A kind of process of the creation method of Virtual Private Network shown in Figure 2
Figure;This method comprises the following steps:
Step S202 is searched in network topology template to be created when receiving the network creation instruction of user's triggering
With the presence or absence of the corresponding node elements of two-layer virtual private network and the corresponding node elements of three-layer virtual special network, and this two
There is dependence between the corresponding node elements of layer virtual private network and the corresponding node elements of the three-layer virtual special network;
Wherein, the node elements of network topology template generally include nodename and configuration information.If current business needs
The combinational network for realizing two-layer virtual private network and three-layer virtual special network can occur two in network topology template simultaneously
The corresponding node elements of layer virtual private network and the corresponding node elements of three-layer virtual special network, and at least a pair of two layers of void
There is dependence between the quasi- corresponding node elements of dedicated network and the corresponding node elements of three-layer virtual special network.
Specifically, it between the node elements with dependence, may need to obtain during a certain node elements creation
The node elements being relied on created after configuration parameter;Then in the configuration information of the node elements, part configuration information is needed
It to be searched from the configuration information for the node elements being relied on by preset order;If from the configuration information of node elements
The order has been found, and has found the nodename for the node elements being relied on from the order, then has illustrated the node name
Claim node elements belonging to corresponding node elements and the order that there is dependence.For example, two layers of void with dependence
Between the quasi- corresponding node elements of dedicated network and the corresponding node elements of three-layer virtual special network, two-layer virtual private network
Corresponding node elements need the configuration after the completion of the corresponding node elements creation of three-layer virtual special network during creation
Information has then generally comprised preset order, and has included in the order in the corresponding node elements of two-layer virtual private network
The nodename of the corresponding node elements of above-mentioned three-layer virtual special network.
Thus, it specifically can node elements type by searching for each node elements in the network topology template and each section
Dependence between point element determines the two-layer virtual private network section whether existed simultaneously in the template with dependence
Point element and three-layer virtual special network node elements.
When network topology template is created, user can click creation service on the page of NFV composer
Button, the simultaneous selection network topology template can trigger the template corresponding network creation instruction.
Step S204, if there is the two-layer virtual private network with dependence in network topology template to be created
Corresponding node elements and the corresponding node elements of three-layer virtual special network, the above-mentioned two-layer virtual for obtaining user setting are dedicated
Information of virtual local area network needed for the corresponding node elements of network and the corresponding node elements of above-mentioned three-layer virtual special network;
Step S206 determines the corresponding node elements of two-layer virtual private network and three according to above-mentioned information of virtual local area network
The VLAN ID of the corresponding node elements of layer virtual private network;
If user knows there is the two-layer virtual private network pair with dependence in the network topology template in advance
The corresponding node elements of node elements and three-layer virtual special network answered can be set simultaneously when triggering network creation instruction
Set required information of virtual local area network;It can also inquire to exist in network topology template in NFV composer and there is dependence
The corresponding node elements of two-layer virtual private network and the corresponding node elements of three-layer virtual special network after, prompt user it is defeated
Enter the information of virtual local area network.
The information of virtual local area network can only include VLAN resource pool ID or VLAN ID, can also simultaneously include that VLAN is provided
Source pond ID and VLAN ID.
Specifically, in the first embodiment: if the information of virtual local area network only includes VLAN resource pool ID, NFV
Composer can find corresponding VLAN resource pool according to VLAN resource pool ID, generally comprise in VLAN resource pool multiple
VLAN ID;It and then is the corresponding node member of the above-mentioned two-layer virtual private network with dependence in the VLAN resource pool
Element node elements corresponding with three-layer virtual special network distribute an available VLAN ID.
In the second embodiment: if the information of virtual local area network includes simultaneously VLAN resource pool ID and VLAN ID,
It is generally necessary to which whether first confirm the VLAN ID available (or occupied), if it is available, the VLAN can be used directly
ID creates the corresponding node elements of two-layer virtual private network and the corresponding node elements of three-layer virtual special network;If can not
With can then distribute an available VLAN ID from the corresponding VLAN resource pool of VLAN resource pool ID.
In addition, in the third embodiment, if above-mentioned information of virtual local area network only includes VLAN ID, and the VLAN
ID it is confirmed it is available after, that is, the corresponding node elements of VLAN ID creation two-layer virtual private network and L 3 virtual can be used
The corresponding node elements of dedicated network.
Step S208, according to the determining VLAN ID creation corresponding node elements of two-layer virtual private network and three layers of void
The quasi- corresponding node elements of dedicated network, obtain include two-layer virtual private network and three-layer virtual special network it is virtual specially
Use network.
In existing way, if it is corresponding to there is the two-layer virtual private network with dependence in network topology template
It is corresponding usually first to create three-layer virtual special network therein for node elements and the corresponding node elements of three-layer virtual special network
Node elements, the configuration information after the creation of the three-layer virtual special network node elements is synchronous, can be obtained corresponding three
Layer virtual private network service;The three-layer virtual special network service that reselection has created, and obtain corresponding VLAN ID, root
According to the corresponding node elements of VLAN ID creation two-layer virtual private network, by the node elements of the two-layer virtual private network
Creation after configuration information it is synchronous, corresponding two-layer virtual private network service can be obtained, and then obtain two layers of final void
Quasi- dedicated network and three-layer virtual special network combinational network.
Creation of the existing way not only bad for two-layer virtual private network and the combinational network of three-layer virtual special network
Process can automate progress, if the user of the northbound interface of NFV composer is unaware of above-mentioned process, be difficult to successfully create
The combinational network of two-layer virtual private network and three-layer virtual special network, it is also difficult to realize with the two-layer virtual private network and
The relevant networking requirements of the combinational network of three-layer virtual special network affect the convenience and user experience of networking layout.
And in present embodiment, due to before creating combinational network, it has been determined that two layers when creating the combinational network
The VLAN ID that Virtual Private Network and three-layer virtual special network are used in conjunction with, therefore the nothing during creation of combinational network
It needs centainly first to create three-layer virtual special network, without the VLAN after the creation of user's manual queries three-layer virtual special network
ID, then create two-layer virtual private network.At this point it is possible to suitable according to the default of each node elements in above-mentioned network topology template
Sequence creates the combinational network, and creation process can also automate realization.
For example, the two-layer virtual private network in combinational network can be created first, then create three-layer virtual special network;?
The three-layer virtual special network in combinational network can be first created, then creates two-layer virtual private network;Or creation group simultaneously
Close the two-layer virtual private network and three-layer virtual special network in network.
The creation method for the Virtual Private Network that disclosure embodiment provides, if in network topology template to be created
In the presence of the corresponding node elements of two-layer virtual private network and the corresponding node of three-layer virtual special network with dependence
Element then obtains the information of virtual local area network of user setting;It is determined on VLAN ID and creation further according to the information of virtual local area network
State the corresponding node elements of two-layer virtual private network and the corresponding node elements of three-layer virtual special network;Which is creating
The corresponding node elements of two-layer virtual private network and the corresponding node elements of three-layer virtual special network with dependence
Before, required information of virtual local area network is set, is no longer needed to by staff's manual queries during creation, so that two layers
The combinational network of Virtual Private Network and three-layer virtual special network creation process can automate progress, and then be advantageously implemented
Network topology is freely defined according to business scenario.
Further, the creation process of the combinational network of two-layer virtual private network and three-layer virtual special network can be certainly
Dynamicization carries out the cost for reducing manual operation maintenance, while user is without being concerned about that two-layer virtual private network and L 3 virtual are special
With the creation of network sequence, also can easily the combinational network of layout two-layer virtual private network and three-layer virtual special network or
Other relevant network construction forms.
Disclosure embodiment also provides the creation method of another Virtual Private Network;This method is based on above-mentioned embodiment party

If information of virtual local area network includes VLAN resource pool ID and VLAN ID simultaneously, illustrate that user is the combinational network
Specify specific VLAN ID;If creating multiple network topology templates in network within a very short time, each VLAN ID's is accounted for
Have little time to update with situation, user may and be unaware of pre-set VLAN ID and occupy;In order to avoid a VLAN
Multiple Virtual Private Networks are created under ID, NFV composer can be looked by relevant interface to controller before using the VLAN ID
The true occupancy of the VLAN ID is ask, to avoid the situation for causing network creation confusion.
If the VLAN ID is occupied, the user VLAN ID can be prompted occupied, user is asked to re-enter void
Quasi- LAN Information;In another way, since information of virtual local area network includes VLAN resource pool ID, can also by with
Family selection is to re-enter information of virtual local area network, or distribute one from the corresponding VLAN resource pool of above-mentioned VLAN resource pool ID
A unappropriated VLAN ID;It is directly corresponding from above-mentioned VLAN resource pool ID or after the above-mentioned VLAN ID of inquiry is occupied
