Problems solved by technology

[0019] 1. Since the existing technology does not summarize the commonality of VLAN Tag operations, it only lists each specific operation, and many VLAN Tag processing scenarios are not considered, such as VLAN staking, NativeVLAN, QinQ, etc., so it is difficult to implement and expand;
[0020] 2. Since only one VLAN Tag's TCI value is defined, if two layers of VLAN Tag operations are required, the existing methods are powerless

Embodiment Construction

[0051] In the following, an ONU providing an Ethernet user port in a GPON system, that is, an ONT is taken as an example to illustrate the message processing method of the ONT of the present invention. For the ONT that provides Ethernet user ports in the GPON system, the user network interface function module is a MAC bridge module, the internal interface is an internal Ethernet port, and the PON protocol processing module is a GPON protocol processing module.

[0052] The present invention redefines the VLAN Tag operation configuration data management entity by summarizing the commonality of VLAN Tag operations. The current VLAN Tag operation on Ethernet packets involves at most two layers of VLAN Tags. After analysis and summary, it is found that all operations on VLAN Tags are some combination of inner layer and outer layer operations. The inner layer adds a layer of VLAN Tag to packets without VLAN Tag, and the outer layer adds another layer of VLAN Tag to packets with a ...

Abstract

The invention relates to report process method of optic network terminal, report processing includes following steps: B1. ONT receives up-bound message from user network interface which is distributed with VLAN operation distribution data property; B2. the user network interface function module of ONT operates the said VLAN Tag based on VLAN operation distribution data property, said operation of VLAN Tag are divided into three types, one is operation of VLAN marking VID and VLAN PRI, two is operation to inner layer, three is operation to outer layer, the ONT executes any type of said operation or combination of said three types. The method of the invention simplifies the operation of VLAN Tag, and the operation mode of VLAN Tag can be expanded flexibly, and it is convenient to realize various operation modes of VLAN Tag.

Description

technical field [0001] The present invention relates to the field of PON (Passive Optical Network, passive optical network), in particular to an optical network terminal (Optical Network Termination, ONT) in a PON system, a message processing method thereof, a method for an ONT to control a VLAN Tag, and an ONT The method of VLAN tag operation in . Background technique [0002] The current broadband access technologies are mainly divided into copper wire access technologies (for example, various DSL (Digital Subscriber Loop, digital subscriber loop) technologies) and optical access technologies. An access network implemented by an optical access technology is called an Optical Access Network (Optical Access Network, OAN). [0003] PON technology is a point-to-multipoint optical access technology. Please refer to FIG. 1 , which is a schematic diagram of a PON system. The PON system is composed of OLT (Optical Line Terminal, optical line terminal), ODN (Optical Distribute N...
