Abstract
A method for realizing VLAN includes submitting description information of VLAN to be set up to VLAN management module by VLAN service module, saving received description information of VLAN by VLAN management module, calling bottom-layer driving to set up said VLAN by VLAN service module.
Description
Technical field
The present invention relates to networking technology area, particularly a kind of particular virtual local area network (Virtual LocalArea Network, implementation method VLAN) and system.
Background technology
VLAN is meant on the basis of switched LAN, adopts the crossed over different segment of network management software structure, the logical network end to end of heterogeneous networks.VLAN can be divided into by type VLAN based on port, based on media interviews control (Medium Access Control, MAC) VLAN of address, based on the VLAN of agreement, based on the VLAN of subnet and based on the VLAN of comprehensive strategic.VLAN has following advantage:
A VLAN is exactly a logical broadcast domain, by the establishment to VLAN, can effectively limit broadcasting, the generation of may command broadcast storm;
By VLAN division principles such as route access list and MAC Address distribution, can control access privilege and logical segment size, the different user group is divided in different VLAN, thereby improves the overall performance and the fail safe of switching network;
For switching Ethernet, if being carried out the network segment again, the certain user distributes, need the network manager that the physical structure of network system is adjusted again, even need append the network equipment, increase the workload of network management; And for the network that adopts vlan technology, a VLAN can be divided into a logical segment according to Ministry Function, group of objects or the network user who uses diverse geographic location, under the situation of not changing the network physical connection, can at random work station be moved between working group or subnet, therefore can alleviate the burden of network management and maintenance work greatly.
In some applied environment; as use fast loop to protect agreement (Rapid Ring ProtectionProtocol; RRPP), Huawei's igmpinternet (Huawei Group Management Protocol; HGMP); or other employings need utilize specific VLAN to propagate the control message when piling up the agreement of (STACK) technology.Described VLAN and general VLAN are different, only are used for propagating the control message, and other message does not allow to enter this VLAN, therefore this VLAN is called the control VLAN (Control Virtual Local Area Network, CVLAN).
The realization principle of CVLAN as shown in Figure 1.Vlan management module 101 provides the outside common interface of creating VLAN to use for protocol module 102.Protocol module 102 sends the instruction of creating CVLAN by this interface to vlan management module 101, and after vlan management module 101 was received instruction, calling driver module 103 was created CVLAN.On the other hand, user 104 also can create and manage various types of VLAN by vlan management module 101 calling driver modules 103, and for the vlan management module, CVLAN and general VLAN are as broad as long.Therefore, CVLAN also is visible for user 104, but in order to satisfy the requirement of monopolizing of 102 couples of CVLAN of protocol module, CVLAN is made all restrictions, and these restrictions include but not limited to:
1), do not allow user 104 deletion CVLAN;
2), not allowing user 104 configuration CVLAN is miscellaneous service VLAN;
3), the fair operation of CVLAN being carried out interpolation, deletion port.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is further elaborated below in conjunction with accompanying drawing.
Core content of the present invention is: the dedicated vlan that defines a kind of brand-new type is specialized in some specific modules use, describe for convenient, keep VLAN (Reserved Virtual Local Area Network with this VLAN that calls the present invention program's definition in the following text, RVLAN), use the module of this VLAN to be called VLAN use module.The present invention program's crucial part is to peel off the relation of RVLAN and vlan management intermodule, also peels off the relation that RVLAN and non-VLAN use the user of module simultaneously.RVLAN not only easily and effectively the VLAN that satisfied uses the monopolize requirement of module to VLAN, also greatly reduces the management difficulty of user to RVLAN simultaneously.
It can be the protocol module that needs VLAN transmitting control message that VLAN uses module, as RRPP module or HGMP module; Also can be other functional modules that need monopolize VLAN, for example use and pile up the module that technology manages the network equipment.
Figure 2 shows that RVLAN realizes principle schematic.Wherein, user 204 is identical with mode described in the background technology by the method for vlan management module 201 calling driver modules 203 other VLANs of establishment except that RVLAN.And the process of establishment RVLAN as shown in Figure 3, comprises the steps:
Step 301:VLAN uses module 202 at first to submit the descriptor of the VLAN that will be created to vlan management module 201;
Step 302:VLAN administration module 201 judges from VLAN to use the pairing VLAN of descriptor of the VLAN of module 202 whether to be created, if then execution in step 305; Otherwise execution in step 303;
The described descriptor of step 303:VLAN administration module 201 storage is labeled as RVLAN with the VLAN of described descriptor correspondence;
Step 304:VLAN uses module 202 notice driver modules 203 to create VLAN, and it is RVLAN that this VLAN is set, and sets up the mapping relations of port and RVLAN, and process ends.
Step 305: use module 202 to return failed message to VLAN, and process ends.
After utilizing above-mentioned steps establishment RVLAN to finish, VLAN uses module 202 to monopolize this RVLAN, and utilizes RVLAN transmission control message; Because user 204 is not the user that VLAN uses module 202, described RVLAN is invisible, not configurable for user 204; Vlan management module 201 is removed the descriptor of record RVLAN, and RVLAN is not done other management.And the effect of the descriptor of the RVLAN of vlan management module 201 record is: prevent that user 204 from creating identical with it VLAN, RVLAN is made amendment or deletes.Its detailed process is:
The descriptor of described VLAN can be the sign of VLAN.
It is example that following specific embodiment will be monopolized VLAN with the RRPP module, further specifies RVLAN and how to create and use.
RRPP needs CVLAN to be used for transmission control message, and other message does not allow to enter CVLAN.RRPP can use the present invention program's RVLAN technology to realize its CVLAN, and its detailed process comprises the steps: as shown in Figure 4
The CVLAN sign that the user of step 401:RRPP module specifies RRPP by order line, the sign of CVLAN that might as well the user is specified is called ID1; Described order behavior RRPP define and VLAN itself it doesn't matter.
Step 402:RRPP module sends the message that comprises described CVLAN sign ID1, the sign ID1 of the CVLAN that the vlan management module stores is received by the external common interface of vlan management module to the vlan management module.
The driver module of step 403:RRPP module invokes bottom is created the pairing RVLAN of VLAN ID1, and described RVLAN is carried out Port Management.
Step 404:RRPP module uses described RVLAN as CVLAN, is used to transmit its control message.
Step 405: if the user of RRPP module will delete this RVLAN, then described user sends the RVLAN that cancellation is designated ID1 by order line.
Step 406:RRPP module sends requirement deletion sign ID1 by the external common interface of vlan management module to the vlan management module, and the vlan management module is then deleted the ID1 that is stored.
The pairing RVLAN of driver module deletion sign ID1 of step 407:RRPP module invokes bottom.
The RRPP module also can be created new RVLAN according to actual needs once more, and it doesn't matter for new RVLAN and original RVLAN; Constructive process is also just the same with the constructive process of the above-mentioned RVLAN that is designated ID1.
The described RVLAN of the present invention program is a kind of dedicated vlan, is characterized in:
1) use the user of module invisible to non-VLAN;
2) must VLAN use the user of module do not need yet to RVLAN create, delete, add/delete operation such as port;
3) specialize in VLAN and use module to use, promptly specialize in VLAN and use the user of module to use, and Common VLAN is the user who has administration authority in the direct network-oriented;
4) RVLAN is not used in the transmission of user data, only is used for transmission control message.
In addition, VLAN uses module that a plurality of RVLAN can be arranged, and described a plurality of RVLAN are independent of each other; Each VLAN uses the RVLAN between the module also to be independent of each other.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
