Abstract
The embodiment of the invention provides a control method of a QinQ access user. The method comprises the following steps: mapping a QinQ interface accessing the QinQ user to a global virtual local area network (VLAN); establishing a global VLAN interface (VLAN If) on the global VLAN; and configuring an IP address on the VLAN If. The embodiment of the invention also provides a control device and a communication system of the QinQ access user. The control method, the control device and the communication system can help various sub-interfaces or physical ports share the same IP address network segment, share the same gateway, and save IP address resources.
Description
Technical field
The present invention relates to the communications field, relate in particular to control method, device and communication system that a kind of QinQ inserts the user.
Background technology
QinQ (802.1Q in 802.1Q, VLAN dual-stack technology) is an expansion VLAN (Virtual LocalArea Network, VLAN) technology in space, by on the basis of 802.1Q label packet, increasing label (Tag) head (one deck public network Tag of one deck 802.1Q again, one deck private network Tag) reaches the function of expanding the VLAN space, can make private network VLAN message transmission public network.
Like this, ISP (Internet Service Provider, the service provider) the different VLAN that only are required to be from same user network of network provide a VLAN ID, have saved the VLAN ID of ISP, with the problem of the ISP network VLAN ID resource anxiety that solves growing tension.Simultaneously also provide a kind of comparatively simple two-layer VPN (Virtual Private Network, VPN (virtual private network)) solution for small-sized metropolitan area network or local area network (LAN).
The QinQ technology has obtained using widely in each operator because it is convenient easy-to-use now.Along with the development of present QinQ business, the application that equipment inserts QinQ user by two-layer Tag more and more widely.For the user that makes access can accesses network, need on equipment, enable the three-layer network pass of a large amount of sub-interfaces as the user, IP address of configuration on each sub-interface, and must dispose different IP addresses between a plurality of sub-interfaces, otherwise IP address conflict can be caused in the identical IP address of configuration on equipment.
As shown in Figure 1, router Router is by QinQ sub-interface access network, and sub-interface 1 SubIf-1 is by the user of the two-layer Tag access 10.1.1.0/25 network segment, and sub-interface 2 SubIf-2 insert the user of 10.1.1.128/25 by two-layer Tag.For each network segment address, a gateway address, broadcast address, network segment address must be arranged.This network segment of 10.1.1.0/25 of sub-interface 1 configuration among Fig. 1, wherein 10.1.1.1 is that gateway address, 10.1.1.127 are broadcast addresses, and 10.1.1.0 is a network segment address, and these several addresses all can't be allocated to the user and use; This network segment of 10.1.1.128/25 of sub-interface 2 configurations, wherein 10.1.1.129 is a gateway address, and 20.1.1.128 is a network segment address, and 10.1.1.255 is a broadcast address, and these several addresses also can't be distributed to the user and use.In this big network segment of 10.1.1.0/24, have like this with regard to 6 IP addresses and can't distribute to user's use.The sub-interface of enabling is many more, just has many more IP addresses can't distribute to the user and uses, and causes the waste of IP address resource.
In like manner, when inserting the user, also there is the problem that causes the IP address resource to be wasted because of enabling physical port and configuration of IP address for the physical port of Router.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of QinQ to insert user's control method, device and communication system, so that insert at QinQ interface under user's the situation, saves the IP address resource.
For solving the problems of the technologies described above, the embodiment of the invention provides a kind of QinQ to insert user's control method, comprising:
The QinQ interface that inserts QinQ user is mapped to overall virtual LAN VLAN;
On described overall VLAN, create overall VLAN interface VLAN If;
Configuration of IP address on described VLAN If.
The embodiment of the invention also provides a kind of QinQ to insert user's control device, comprising:
Map unit, the QinQ interface that is used for inserting QinQ user is mapped to overall VLAN;
First creating unit is used for creating overall VLAN interface VLAN If on overall VLAN;
First dispensing unit is used for configuration of IP address on VLAN If.
The embodiment of the invention also provides a kind of communication system, and described system comprises router, and described router inserts QinQ user by QinQ interface, and described router further comprises:
Map unit, the QinQ interface that is used for inserting QinQ user is mapped to overall VLAN;
First creating unit is used for creating overall VLAN interface VLAN If on overall VLAN;

Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
The embodiment of the invention one:
As shown in Figure 2, present embodiment is when inserting the user by QinQ interface (for example If-1 and If-2), direct configuration of IP address on sub-interface or physical port not, but QinQ interface is mapped to overall VLAN, configuration of IP address on the interface VLAN of overall VLAN If, a plurality of little network segments can be merged into the big network segment like this, save the IP address resource.
Please refer to shown in Figure 3ly, the embodiment of the invention one QinQ inserts user's control method, comprising:
In the embodiment of the invention, QinQ interface is mapped to overall VLAN is meant the VLAN Tag that two layers of Tag of QinQ interface is all replaced with public network.
In the practical application, the technical scheme of embodiment one can have two kinds of embodiments, describes respectively with embodiment two and embodiment three below.
The embodiment of the invention two:
As shown in Figure 4, in the present embodiment, when inserting the user by QinQ interface, need to create sub-interface SubIf (for convenience of description, present embodiment is an example to create 2 sub-interface SubIf-1, SubIf-2), but direct configuration of IP address on sub-interface not, but sub-interface is mapped to overall VLAN, configuration of IP address on the interface of overall VLAN can be merged into the big network segment with a plurality of little network segments like this, saves the IP address resource.
Please refer to shown in Figure 5ly, present embodiment two QinQ insert user's control method, comprising:
The sub-interface SubIf quantity of creating on router Router is decided according to the practical application scene.After SubIf-1, SubIf-2 create, will insert QinQ user by two-layer Tag.
At this moment, sub-interface SubIf-1, SubIf-2 all are mapped to overall VLAN, and the ID of overall VLAN can be 100, and promptly VLAN 100.
In the present embodiment, can be on overall VLAN 100, to create three layer interface VLAN If.
In the present embodiment, can be on VLAN If configuration of IP address: 10.1.1.0/24.
The embodiment of the invention three:
As shown in Figure 6, in the present embodiment, when inserting the user by QinQ interface, with two layers of Tag information of physical port (for convenience of description, present embodiment is an example with 2 physical port Port-1, Port-2) be mapped to overall VLAN, configuration of IP address on the interface of overall VLAN can be merged into the big network segment with a plurality of little network segments like this, saves the IP address resource.The difference of present embodiment and embodiment two is that present embodiment need not to create sub-interface, but directly utilizes physical port, can save interface resource.
Please refer to shown in Figure 7ly, present embodiment three QinQ insert user's control method, comprising:
At this moment, physical port Port-1, Port-2 all are mapped to overall VLAN, and the ID of overall VLAN can be 100, and promptly VLAN 100.
In the present embodiment, can be on overall VLAN 100, to create three layer interface VLAN If.
In the present embodiment, can be on VLAN If configuration of IP address: 10.1.1.0/24.
