Example Embodiment

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0019] In this embodiment, an intermediate device is added to simultaneously implement the VLAN data packet translation function and the VLAN tag data filtering function. Such as figure 1 As shown, in this embodiment, the intermediate device (gpon0.ani) is set between the GPON interface device (gpon0) and the gateway device (veip0), and the VLAN packet translation function (ExtVlan) is implemented between the veip0 device and the gpon0.ani device. ), the VLAN tag data filtering function (VlanFlt) is implemented between the gpon0.ani device and the gpon0 device.

[0020] The above are only the...

Abstract

The invention provides a realization method of a virtual local area network (vlan) function of GPON upstream interfaces. The method comprises the following steps: additionally installing intermediate equipment between GPON interface equipment and gateway equipment; respectively realizing a VLAN data packet translation function and a VLAN mark data filtering function on two sides of the intermediate equipment. In the invention, the VLAN data packet translation function and the VLAN mark data filtering function can be simultaneously realized so as to realize integrity of the VLAN function.

Description

technical field [0001] The present invention relates to the technical field of PON (passive optical network, passive optical network), in particular to a method for realizing the vlan function of the uplink interface of GPON (gigabit passive optical network). Background technique [0002] The 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 optical access technologies is called OAN. (optical access network, optical access network). [0003] In optical access technology, PON technology is a point-to-point transmission optical access technology, PON system includes: [0004] OLT (Optical Line Terminal, Optical Line Terminal): Provides a network-side interface for OAN and connects to one or more ODNs; [0005] ODN (Optical Distribute Network, optical distribution network): Passive ...
