Description
Technical field
The present invention relates to the fields gigabit passive optical network (GPON), and in particular to terminal device number in a kind of GPON system
According to the implementation method of QINQ.
Background technique
Currently, broadband access technology is broadly divided into copper wire access technology (such as various DSL technologies) and soft exchange technology, and
Passive optical network (PON, Passive Optical Network) technology is a kind of soft exchange technology of point-to-multipoint transmission, main
It to include Ethernet passive optical network (EPON, Ethernet Passive Optical Network) and G bit passive light net
Network (GPON, Gigabit Passive Optical Network) etc., PON system is usually by OLT (Optical Line
Terminal, optical line terminal), ODN (Optical Distribution Network, optical distribution network) and ONU/ONT
(Optical Network Unit, optical network unit/Optical network terminal, optical network device) composition, such as
Shown in Fig. 1.
As network environment becomes increasingly complex, the ONU hung under OLT is also more and more, and the function of ONU is also more multiple
It is miscellaneous, therefore, carry out the VLAN interpretative function that service fulfillment needs OLT to support the Complex Flexible based on ONU.Current GPON system
The VLAN interpretative function and QINQ function that OLT is supported, are based only upon VLAN ID, do not support VLAN interpretative function based on ONU and
QINQ function.
Under certain project scenarios, for data service, the upper all user vlans of ONU are all identical, by OLT it
Afterwards, it needs according to different ONU plus different CVLAN (user vlan), for example, ONU 1 is needed the CVLAN 41 of ONU1
It is converted into 300, ONU 2 and needs for the CVLAN 41 of ONU2 to be converted into 301, ONU 3 needing to change into the CVLAN 41 of ONU3
303……；And SVLAN (service provider VLAN) is related to PON mouthfuls, different PON mouths has different SVLAN；As it can be seen that currently, not
The terminal of supported bilayer VLAN cannot carry out VLAN translation based on ONU, realize QINQ function, have been unable to meet engine request.
Summary of the invention
The technical problem to be solved by the present invention is to the terminal device of supported bilayer VLAN can not in current GPON system
The problem of flexibly realizing QINQ.
In order to solve the above-mentioned technical problem, it is set the technical scheme adopted by the invention is that providing terminal in a kind of GPON system
The implementation method of standby data QINQ, comprising the following steps:
