Problems solved by technology

[0020] 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;
[0021] 2. Since only one VLAN Tag TCI value is defined, if two layers of VLAN Tag operations are required, the existing methods are helpless

Embodiment Construction

[0052] 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.

[0053] 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 a method for processing a message of an optical network terminal. When an uplink message is processed, the method comprises the following steps: B1, ONT receives the uplink message from a user network interface configured with operation configuration data attribute of a virtual local area network VLAN; and B2, a user network interface functional module of the ONT executes operation of the virtual local area network tag VLAN Tag on the uplink message according to the VLAN operation configuration data attribute; the operation of the VLAN Tag is divided into three types, the first one is operation to VLAN identification VID and operation to VLAN priority; the second one is operation to an inner layer; the third one is operation to an external layer; and the ONY executes operation of any type or an arbitrary combination of operations of the three types. The method simplifies the operation of the VLAN Tag, can flexibly expand operation mode of the VLAN Tag, and can conveniently realize diversified VLAN Tag operation mode.

Description

technical field [0001] The present invention relates to PON (Passive Optical Network, passive optical network) field, relate in particular to a kind of optical network terminal (Optical Network Termination, ONT) in the PON system and its message processing method and ONT control VLAN Tag method and in ONT The method of performing VLAN Tag operation in Background technique [0002] Current broadband access technologies are mainly divided into copper wire access technologies (such as 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 an optical access technology for point-to-multipoint transmission. see figure 1 , which is a schematic diagram of the PON system. The PON system consists of OLT (Optical Line Terminal, Optical Line Terminal), ODN (Optical Distribute...
