step 201, identifying a user access OLT;
step 202, allocating an inner layer VLAN for a user;
step 203, judging whether flag distributed by all inner layer VLANs is 1, if yes, executing step 204, and if not, executing step 205;
step 204, selecting an inner layer VLAN with the least repeated distribution times;
step 205, sequentially selecting an inner layer VLAN from the unallocated inner layer VLAN set;

Specifically, the identification of the user access to the OLT information and the VLAN assignment based on the detailed record information recorded by the OLT are started, and the information identification is not limited to the identification in the order information.
The method comprises the steps of starting to allocate inner layer VLANs for users, firstly determining whether the inner layer VLANs in a specified range are completely allocated, and if so, selecting the inner layer VLAN with the least repeated allocation times according to fields of 'repeatedly allocated inner layer VLANs and repeated allocation times' in inner layer VLAN table information; if not, one inner layer VLAN is selected in sequence according to the field of the inner layer VLAN set which is not repeatedly allocated in the inner layer VLAN table information, and the sequence can be but is not limited to the sequence number of the array of the stored VLAN information from small to large.
And updating the inner VLAN table after the inner VLAN is selected, such as repeatedly allocated inner VLAN, repeated allocation times, an inner VLAN set without repeated allocation and other change information.
And identifying the networking type of the user, selecting a nonrepetitive outer VLAN in the switching domain of the networking 1 if the networking type is the networking 1 type, ensuring that the outer VLAN in the switching domain is not repeated, and selecting the nonrepetitive outer VLAN in the collision domain of the networking 2 if the networking type is the networking 2 type, and ensuring that the outer VLAN in the collision domain is not repeated. Here, the type of the networking 1 refers to dual-uplink aggregation switch networking, and the type of the networking 2 refers to single-uplink flat networking.
Before distribution, firstly, judging whether flag marks distributed by all outer layer VLANs in different switching domains or conflict domains are 1 or not. If flag is not 1, it indicates that the outer layer VLAN is not repeatedly allocated, and according to the selected inner layer VLAN, the repeated condition of the inner layer VLAN and the selected outer layer VLAN corresponding to the repeated inner layer VLAN, one outer layer VLAN is selected to ensure that the combination of the inner layer VLAN and the outer layer VLAN in the exchange domain or the collision domain is unique, which is specifically as follows:
if the inner layer VLAN is distributed in the field of the unallocated inner layer VLAN set in the inner layer VLAN table, the outer layer VLAN can freely select the distributed outer layer VLAN or the unallocated outer layer VLAN in the exchange domain or the conflict domain according to the requirement;
if the inner layer VLAN is distributed in the field of the distributed inner layer VLAN set in the inner layer VLAN table, the repeated distribution times need to be confirmed in the field of the repeated distributed inner layer VLAN and the repeated distribution times, the corresponding outer layer VLAN is found out in the field of the repeated distributed inner layer VLAN and the outer layer VLAN set according to the times, and finally, a former found outer layer VLAN is selected to be used repeatedly in an exchange domain or a collision domain, namely, the uniqueness of the inner layer VLAN and the outer layer VLAN is ensured.
If the flag is 1, the outer layer VLAN is repeatedly allocated, and the actual situation is unlikely to occur, so the system sets to indicate that the outer layer VLAN is unavailable for resource allocation.
And after the outer layer VLAN is distributed, updating an outer layer VLAN table, wherein the outer layer VLAN table comprises information of the distributed outer layer VLAN set, the unallocated outer layer VLAN set and the like.
The method for allocating the inner and outer layer VLANs of the home broadband service provided by the embodiment of the invention realizes the automatic allocation of the inner and outer layer VLANs meeting QinQ standards aiming at the home broadband service, and in a GPON network and a metropolitan area network, under the scene of adopting the QinQ technology to expand VLAN resources to identify different customers, through the automatic identification of network topology, the automatic allocation and conflict resolution rules of the inner and outer layer VLANs are designed, the automatic allocation and issuing configuration of the VLANs are realized, the management configuration efficiency of the VLAN resources is improved, errors possibly generated when the inner and outer layer VLANs are manually allocated are avoided, the IT automatic supporting capability is enhanced, the accuracy is improved, and the cost is saved.
On the basis of the above embodiment, after the outer VLAN assignment is performed according to the user access networking type and the outer VLAN table, the method further includes:
and judging whether the user inner layer VLAN and the user outer layer VLAN have conflict in the corresponding exchange domain or conflict domain, and if yes, prompting exception.
If the user inner layer VLAN and the user outer layer VLAN do not have conflict in the corresponding exchange domain or conflict domain, the method further comprises the following steps:
synchronizing user VLAN distribution management information, wherein the user VLAN distribution management information comprises the user access information table, the inner layer VLAN table, the outer layer VLAN table, the user inner layer VLAN and the user outer layer VLAN.
In the embodiment of the invention, after the inner and outer layer VLANs are distributed, the confirmed inner and outer layer VLANs check again in the whole exchange domain or the conflict domain to confirm whether the conflict exists.
The purpose of this step is mainly to check whether the currently allocated inner and outer layer VLANs uniquely identify the user in the switching domain or the collision domain, so the premise is that the database needs to keep inner and outer layer VLAN identification records for all users in the collision domain or the switching domain, if there is a collision, an exception is prompted, and a system collision check module needs to be manually used to confirm the collision.
If no conflict exists, the user information identified in the embodiment of the invention, the distributed inner and outer layer VLAN information and the comprehensive resource management system information are synchronized, wherein the information synchronization when the user logs off is also included, and the comprehensive resource management system, the inner and outer layer VLAN tables and the user subscription information are bidirectionally and automatically synchronized.
After the information synchronization is realized, the network management server is connected through the information synchronization module, and the automatic configuration issuing is realized, which comprises the following steps:
the service port is issued to the OLT equipment to realize the automatic configuration of the service port;
if the situation is networking 1, sending VLAN configuration to a main device in the OLT dual-uplink convergence exchange;
