Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] figure 1 Shown is the implementation flowchart of the passive optical network OLT equipment QINQ message processing method provided by the embodiment of the present invention, and its specific steps are as follows:

[0050] In step S101, a data stream sent from an ONU is received through a PON interface.

[0051] In step S102, the received data flow is analyzed for layer 2 data, and a layer 2 data table corresponding to the data flow is obtained. The layer 2 data table includes fields and value options, wherein the field options include board ID, PON port, LLID, L2DA, L2SA, L2TYPE, CVID, a...

Abstract

The present invention relates to the technical field of passive optical network systems, and provides a method and system for processing QINQ messages of passive optical network OLT equipment. The method includes: receiving data streams through a PON interface, and analyzing the data streams on the second-layer data and third-layer data , obtain the second-tier data table and third-tier data table, and generate a QINQ table, transfer the value corresponding to the field to be matched in the QINQ table to the register, locate the search processing function, and perform rule matching. If the match is successful, the data stream Implement the identification of the outer QINQ label SVID, and send the data flow to the corresponding port, so as to realize the configuration of QINQVLAN on the OLT device, and carry out the identification of the outer QINQ label SVID on the data flow received by the OLT from the ONU, which improves the quality of the QINQ message. The processing speed optimizes the network configuration of the EPON+EOC system and improves the user's Internet access speed.

Description

technical field [0001] The invention belongs to the technical field of passive optical network systems, and in particular relates to a method and system for processing QINQ messages of passive optical network OLT equipment. Background technique [0002] Ethernet Passive Optical Network (EPON) technology is a point-to-multipoint passive optical network access technology based on Ethernet technology, which uses passive optical network (Passive Optical Network, PON ) technology, using the Ethernet protocol at the link layer, using the PON topology to achieve Ethernet access, which combines the low cost, high bandwidth, strong scalability, and flexible and fast services of PON technology and Ethernet technology Advantages, it has gradually become the most effective communication method for broadband access networks. [0003] With the acceleration of triple play process, EPON+EOC system is widely used, broadband Internet access, and TV-on-demand services are becoming more and mo...
