Embodiment Construction

[0064] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0065] The basic principle of the present invention is to increase the new configuration attribute Native VLAN in the VLAN tag operation configuration data (VLAN TaggingOperation Configuration Data) ME, when the Ethernet port receives the upstream Ethernet message from the equipment connected with it, if there is no A message with a VLAN tag (label) will be marked with a VLAN tag specified in the Native VLAN attribute and then forwarded. If a message with a VLAN tag has already been marked, only the message will be forwarded without changing the original VLAN tag of the message; When an Ethernet packet is sent to the connected device, if the VALNtag of the downlink Ethernet packet is the VLAN tag specified in the Native VLAN attribute, the VLAN tag will be removed before being sent to the connected device. If the VLAN tag of the Ethernet packet i...

Abstract

The disclosed process method for Ethernet message on ONT comprises: a. ONT receives Ethernet message from user interface, if there is no VLAN tag in the message, adds VLAN tag in UNI Native VLAN attribute to send to GPON protocol process module, or sends directly; and b. ONT receives the down message with VLAN tag from the process module, if the VLAN tag same as the appointed one in the Native VLAN attribute of user interface, eliminates the VLAN tag in message to send the message to the related device, or else sends message to the connected device directly.

Description

technical field [0001] The present invention relates to the technical field of PON (passive optical network), and in particular, relates to the technology of an optical network unit (ONT) for processing Ethernet messages. 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. The access network implemented by the optical access technology is called an optical access network (OAN). [0003] Among optical access technologies, PON (passive optical network) technology is a point-to-multipoint optical access technology. The PON system is shown in Figure 1, where: [0004] OLT (Optical Line Terminal): Provides a network-side interface (SNI) for OAN and connects to one or more ODNs; [0005] ODN (Optical Distribute Network): Passive optical splitting device, ODN transmits the downstream data of ...
