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...
