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 invention relates to the technical field of passive optical network systems, and provides a method and a system for processing passive optical network (PON) optical line terminal (OLT) equipment QINQ messages. The method includes receiving a data stream through a PON interface, performing two-layer data analysis and three-layer data analysis to the data stream to acquire a two-layer data table and a three-layer data table and generate a QING table, inputting values corresponding to to-be-matched fields in the QING table to a register, locating to search a processing function, performing rule matching, executing outer QINQ label SVID identification to the data stream and sending the data stream to a corresponding port when rule matching successes, thereby achieving configuration of QINQVLAN on the OLT equipment. Since the data stream received by the OLT from the ONU is subjected to the outer QINQ label SVID identification, QINQ message processing speed is increased, network configuration of EPON+EOC systems is optimized, and network speed for users is increased.

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. It adopts 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 more...
