Background
In the field of communications technology, VLAN is an important technology, and VLAN (virtual local area network) is a logical segmentation of network users connected to a second layer switch port, and is not limited by physical locations of the network users but performs network segmentation according to user requirements. A VLAN may be implemented at a switch or across switches. VLANs may be grouped according to the location, role, department of the network user or according to the application and protocol used by the network user. The switch-based virtual local area network can solve the problems of conflict domain, broadcast domain and bandwidth for the local area network.
VLANs are commonly available in the form of untagged VLANs, single-layer VLAN tags, QINQ (dual-layer VLAN tags), and the like. VLANs may be added or deleted or modified as the data stream passes through a data office. The modification can be flexible, such as only transmitting, not making any modification, or adding a layer of VLAN to the data without VLAN tag, or even modifying the TPID of VLAN tag of the data flow, etc.
However, at present, each equipment manufacturer has no unified standard for VLAN service forms, and even the difference is very large in the field of different types of equipment. There are only a few common and unprofitable specifications, such as ACCESS/TRUNK mode, which is common for switches. But often differ from manufacturer to manufacturer. Making the device software somewhat confusing in its definition when handling VLAN related traffic.

In a preferred embodiment of the present invention, the direction of the configuration data is configuration in or configuration out.
As a preferred embodiment of the present invention, the action processing of step (4) includes deleting, adding, modifying, copying, passing through, discarding or modifying the priority.
As a preferred embodiment of the present invention, the filtering condition in step (3) includes the number of data layers of a data VLAN, a VLAN value of each layer, a TPID value, a PRIO value, or a CFI value.
In the specific implementation mode of the invention, a software framework for uniformly analyzing VLAN services is disclosed, so that the software is uniformly analyzed when processing the VLAN services, the development time is reduced by uniformly storing the software, and the software of the same manufacturer can be uniformly developed and processed on different types of data equipment even through the invention.
The basic flow of the invention is as follows:
1. judging the direction of the data;
2. and filtering data to obtain the number of layers of the VLAN to be filtered and the VLAN ID value of the number of the layers of the VLAN to be processed.
3. Processing the data of each filtering item in the step 2, and processing the VLAN data according to the number of layers, the filtering condition and the adding and deleting condition of the VLAN;
4. and transmitting the analysis result to other modules, and uniformly performing subsequent processing, such as hardware configuration, configuration storage and the like, according to the analysis result.
The present invention includes analyzing and unifying VLAN configuration of one device, and the configuration may be issued from the device in common way. The present invention analyzes configurations into a unified multi-element set: direction, filtering and action, and sending the configuration to other modules of the software for processing with unified logic
The direction of the tuples in the analysis result refers to the matching-out or matching-in of the data, and the filtering of the tuples in the analysis result refers to the requirement of subsequent action processing on the data meeting the conditions. The filtering conditions include the number of data VLAN layers, VLAN values of each layer, TPID value, PRIO value and CFI value. Wherein, the TPID value indicates a signed protocol identification value, the CFI value indicates a canonical format indicator value, and the PRIO value indicates a priority value. The condition for filtering may be a single condition or a combination of a plurality of conditions, or a combination of a plurality of unspecified conditions + specified conditions. The processing after filtering refers to processing on each layer of VLAN such as deletion, addition, modification, duplication of values between layers, transparent transmission, or discarding. After the multi-tuple is analyzed into direction, filtered and processed, the result is sent to other modules of the software for validation, storage and the like.
The specific operation steps of the invention according to the basic flow are as follows:
the invention needs configuration, the configuration is different according to different sources of equipment, if the equipment is a switch, the equipment can be WEB or a command line; if the PON is adopted, the network management is possible.
And then, analyzing the direction of the configuration data according to the configuration, wherein the direction is matched IN or matched OUT, the data enters the equipment and the data exits from the equipment, and the direction is called IN or OUT for short.
The software will then configure the VLAN layer numbers associated with the analysis configuration, e.g., layer 0, layer 1, layer 2 … …, etc.
The number of layers is briefly summarized as follows:
if the data is layer 0, only one processing method is available, and the layer 0VLAN is called UNTAG.
If the data is layer 1, the software analyzes the configuration for certain VLANs, such as VLAN100, called SINGLE TAG 100, and VLANs other than the designated 100VLAN, called DEFAULT _ VLAN, for another type of processing.
If the data is 2-layer, the outer layer or the inner layer or both layers are designated and processed.
And finally, processing when the analysis data is IN or OUT.
The action process is briefly summarized as follows:
the data of UNTAG is transmitted through, or a layer 1 VLAN is added or a layer 2 VLAN is added, and the ID/priority/TPID of the VLAN can be respectively assigned or simultaneously assigned.
Layer 1 VLAN data, an example of which is designated VLAN 100. After the above-described layer number processing, the action processing may include transparent transmission, deletion of the VLAN100, addition of a layer of VLAN, even addition of two layers of VLANs, or modification of the VLAN100 to 200, or modification of only the VLAN priority. Other single-layer VLAN data are modified.
After the above layer number processing, the processing of the data of the layer 2 VLAN may be deleting a layer of VLAN, deleting a layer 2 of VLAN, adding a layer 2 of VLAN, modifying a VLAN, and the like.
After the above analysis, the final processing result is sent to other modules in a multi-element array, for example, to the HAL module, the configuration hardware is finally validated, and the configuration can be uniformly stored when the final processing result is sent to the configuration management module.
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

the direction is as follows: IN;
and (3) filtering: SINGLE _ TAG _100_ PRIO _ 1;
the actions are as follows: VLAN conversion 200_ priority conversion 3;
the direction is as follows: IN;
