Description
Technical field
The present invention relates to VLAN construction technique field, and in particular to one kind uses SDN in traditional routing equipment
The network architecture go to build VLL manage concentratedly and smart allocation VLL VLL control device.
Background technology
Network Development makes rapid progress, the customer volume of network also in the growth of explosion type, by interchanger for main body constitute two
Layer network gradually seems can not meet the demand of user.For example, when a large enterprises all set up company respectively in Shanghai and Guangzhou,
And it is required that it is in same Intranet between company.If with traditional method using two layers of method of interchanger by Intranet
Erect and, this is clearly unpractical.Therefore, virtual local area network technology（VPN）Arise at the historic moment.
The major function of virtual local area network technology is to set up VLL by three-layer network, then in specific flow
Communication is encrypted to data message above or many layer data bags are Resealed and identifies whether to be desirable by special equipment
The message for the treatment of.Realizing the mode of VLAN has many kinds, is mainly based upon agreement to classify, traditional implementation method one
As be to be realized by agreements such as GRE, IPsec, although this several technology can realize the function of VPN, its all be carry
On traditional physical equipment, and because the reason for being distributed network on legacy network, such VPN management gets up just to become
It is complex.Although operation maintenance personnel also uses the methods such as webmastering software and goes to manage the various work(in each conventional physical equipment
Can, but each enterprise may use different types of equipment in actual environment, various physical equipments are managed simultaneously and is wanted
Each producer's open interface seems unactual to management software again.
In a word, it is not enough below existing virtual local area network technology generally existing at present：1st, temporarily only support on legacy network
Equipment, manage more difficult in distributed network；2nd, configure complex, O＆M cost is higher；3rd, relatively it is adapted to individual
One entirety is used, what is used during for entirety to entirety is inefficient；4th, when flow has flowed out the edge road of enterprise
By device, flow will be no longer controlled, and the quality for flowing cannot be guaranteed.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of configuration is simple, O＆M cost is low, entirety makes to overall
With efficiency high, flow rates controlled in traditional routing equipment using SDN framework remove to build VLL can concentrate tube
The VLL control device of reason and smart allocation VLL.
To achieve the above object, the present invention is adopted the following technical scheme that：
Realize the VLL control device under SDN frameworks on traditional routing, including the first VLL equipment, second it is virtual specially
Line equipment and controller, the first VLL equipment, the second VLL equipment are connected to public network and enterprise margin
Between router, VLL is set up between the first VLL equipment, the second VLL equipment, controller is connected to virtually
On special line, vxlan functions are opened on VLL, 8bit is taken in the extended field of the vxlan header on vxlan messages
As VLL identification number, wherein 2bit is used for telling that controller enterprise will use this VLL that remaining byte is used
Make extension next time；First VLL equipment, the second VLL equipment are built-in with the virtual switch for supporting Openflow agreements
Machine, data message flows into the first VLL equipment or the second VLL equipment and is sent to the virtual port of virtual switch
In, the flow table on packet and matching virtual interchanger is untied using the protocol stack of kernel, flow table is performed by virtual switch
Action, sends out data message designated port and is traditionally forwarded to the second VLL equipment or the first VLL sets
It is standby.
Further, the first VLL equipment, the second VLL equipment can provide record and be currently in use void
Intend the IP quantity of special line passage, each can first send a data message and tell controller using the IP of the VLL passage
It is using this passage, controller to receive data message and generate a json file, records VLL passage
Usage quantity, when threshold values is used more than, controller can issue flow table go to change ensuing IP go to use other one it is virtual
Special line passage.
The present invention has the advantages that：
The VLL control device under SDN frameworks is realized on traditional routing of the present invention, it can be used in traditional routing equipment
SDN framework goes to build VLL and can manage concentratedly and smart allocation VLL, with configuration is simple, O＆M cost
The characteristics of low, entirety high to overall service efficiency, flow rates controlled.
Brief description of the drawings
Fig. 1 is the rough schematic that the VLL control device under SDN frameworks is realized on traditional routing of the present invention.
In figure：1st, the first VLL equipment；2nd, the second VLL equipment；3rd, controller.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the invention will be further described, in order to be more clearly understood that this
The claimed technological thought of invention.
Realize the VLL control device under SDN frameworks on traditional routing of the present invention as shown in Figure 1, including first virtual
Special line equipment 1, the second VLL equipment 2 and controller 3, the first VLL equipment 1, the second VLL equipment 2 are distinguished
It is connected between public network and enterprise edge router, is built between the first VLL equipment 1, the second VLL equipment 2
Vertical VLL, controller 3 is connected on VLL, vxlan functions is opened on VLL, on vxlan messages
8bit is taken in the extended field of vxlan header as VLL identification number, wherein 2bit is used for telling the enterprise of controller 3
This VLL is used, remaining byte is used as to extend next time；First VLL equipment 1, the second VLL equipment 2
The virtual switch for supporting Openflow agreements is built-in with, it is virtual special that data message flows into the first VLL equipment 1 or second
Line equipment 2 is simultaneously sent in the virtual port of virtual switch, unties packet using the protocol stack of kernel and matching virtual is exchanged
Flow table on machine, the action of flow table is performed by virtual switch, data message is sent out into designated port and is traditionally forwarded
To the second VLL equipment 2 or the first VLL equipment 1.
Specifically, the first VLL equipment 1, the second VLL equipment 2 can provide record being currently in use virtually specially
The IP quantity of line passage, each using the IP of the VLL passage can first send a data message tell controller 3 it
Use this passage, controller 3 to receive data message and generate a json file, record making for VLL passage
With quantity, when threshold values is used more than, controller 3 can issue flow table go to change ensuing IP go to use other one it is virtual specially
Line passage.
For a person skilled in the art, technical scheme that can be as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the protection model that should all belong to the claims in the present invention
Within enclosing.
