Accompanying drawing explanation
For the above and other purpose of the present invention, feature, advantage can be become apparent with embodiment, appended
Being described as follows of accompanying drawing:
Fig. 1 is the structural representation of the system of the virtual net user access of the present invention；
Fig. 2 is the schematic flow sheet of the method for the virtual net user access of the present invention；
Fig. 3 is that the present invention one preferably utilizes local dns to carry out the signaling process of multichannel recurrence DNS query
Schematic diagram, wherein local dns is to be deployed in the incoming end of virtual net and be connected with incoming end server.
Detailed description of the invention
It is hereafter to coordinate appended accompanying drawing to elaborate for embodiment, but the embodiment provided be not used to limit
The scope that the present invention processed is contained.
The present invention is mainly by disposing at least one local dns in virtual net, integrates on virtual net
During multiple ISP resource, can by local dns to multiple higher level DNS (include operator DNS and
Root DNS) carry out multichannel recurrence DNS query, i.e. resolve the DNS request of user, and by analysis result
Be combined with a predetermined policy, obtain an objective result being suitable for, for the flow dispatching patcher stream to user
Amount carries out the scheduling shunted.
As it is shown in figure 1, the system that the virtual net user of the present invention accesses is to be applied to a virtual net (such as
SDN etc.) in, described virtual net includes and is positioned at the backbone network server of backbone network end, is positioned at and connects
Entering the incoming end server of end and be positioned at the port of export server of the port of export, user is to be serviced by incoming end
Device accesses described virtual net.In other embodiments, incoming end can also include client device, Yong Huke
To be to access described incoming end server by described client device, and then access in described virtual net.
The present invention specifically, at least one end in incoming end, backbone network end and the port of export of described virtual net
A upper deployment at least local dns, utilizes described local dns can carry out multichannel recurrence DNS query.
In the embodiment shown in fig. 1, it is on incoming end, backbone network end and the port of export, be respectively provided with a this locality
DNS, described local dns respectively with client device, incoming end server, backbone network server and go out
Mouth end server correspondence connects, and so, utilizes described local dns, coordinates flow scheduling system to do
To client shunting, incoming end shunting, backbone network shunting and port of export shunting.However, it will be understood that
The deployed position of above-mentioned local dns is not intended as limitation of the present invention.
In conjunction with Fig. 1, and refer to Fig. 2, the method that the virtual net user of the present invention accesses includes:
(1) DNS proxy is utilized to dispose at least one local dns in a virtual net；
(2) when described local dns receives the DNS request that user sends, described DNS is forwarded
Request is to multiple higher level DNS, and the DNS and root DNS of the most multiple operators, to carry out domain name mapping；
(3) the plurality of higher level DNS returns analysis result extremely described local dns, and by described parsing
Result stores as data；
(4) one policy calculation devices select an objective result according to a predetermined policy from described analysis result,
And described objective result is sent to described local dns；
(5) described local dns returns described objective result to described user.
In the present invention, during described analysis result can be stored in described policy calculation device.Described analysis result example
As included Target IP information or cname (canonical name) information etc., all can be used for network traffics tune
The foundation of degree and/or the relevant information of the verification as dns resolution result.
In the present invention, it is also possible to use a flow dispatching patcher according to described objective result to described user's
Flow carries out the scheduling shunted.Wherein, described flow scheduling system also can be according at least one detectable resource
Information strategy self-defined with combines scheduling and the management carrying out flow, and wherein, described detectable resource is believed
Breath includes the information such as performance, cost performance, bandwidth, protocol type, IP address, domain name and server load.
Below in conjunction with Fig. 3, as a example by disposing local dns on incoming end server, describe this in detail
The method that bright virtual net user accesses:
1. user's local dns request domain name mapping, such as www.a.com on incoming end server；
2. the local dns on incoming end server forwards user to ask ISP1 DNS, ISP2 simultaneously
DNS and root DNS；
3. ISP1 DNS, ISP2 DNS and root DNS return analysis result to access from each different paths
Local dns on end server；
4. the analysis result returned is stored in policy calculation device；
5. policy calculation device is according to the suitable target ip address of policy selection, or cname returns to access
Local dns on end server；
6. the local dns on incoming end server returns result (i.e. IP address or cname) to user.
Thus, the different target IP ground that customer flow can resolve on different DNS according to same domain name
Location or cname, do the scheduling shunted.Scheduling can also be according to performance, cost performance, bandwidth, protocol class
All resources that can detect such as type, IP address, domain name, server load combine with self-defined strategy
Carry out flow scheduling and management.
In the embodiment shown in fig. 3, described local dns and described policy calculation device are as two solely
Vertical parts are separately described.But it is understood that, the two can also combine, such as by institute
Stating policy calculation device to be incorporated in described local dns, this is equally not as limitation of the present invention.
To sum up, in the system that the virtual net user of the present invention accesses, described local dns may be used for: connects
Receive the DNS request that a user sends, and forward described DNS request extremely multiple higher level DNS, to enter
Row domain name mapping；Receiving the analysis result that the plurality of higher level DNS returns, wherein said analysis result is made
It is stored in a policy calculation device for data；Receive described policy calculation device according to a predetermined policy from described parsing
The objective result selected in result, and return described objective result to described user.
By the method and system of the present invention, when virtual net is integrated multiple ISP resource, can be transparent
For the Target IP of user's reasonable positioning, and carry out automatic shunt and optimize network.The present invention is a transparent side
Case, supports all of normal access, it is not necessary to particularly FTP client FTP, should in existing all the Internets
With can directly use.
Although the present invention is disclosed above with embodiment, so it is not limited to the present invention, any familiar
This those skilled in the art, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations, therefore
Protection scope of the present invention is when being defined in the range of standard depending on appending claims.
