Embodiment Construction

[0035] The core idea of ​​the present invention is: first, add the user port and the uplink port to the service VLAN of VLAN uplink N: 1 aggregation at the same time, and establish the entry VLAN mapping relationship table, the uplink port mapping relationship table and the egress VLAN mapping relationship table in advance ; Then perform uplink N:1 aggregation processing and downlink 1:N conversion processing according to the ingress VLAN mapping relationship table, the uplink port mapping relationship table and the egress VLAN mapping relationship table.

[0036] Such as figure 1 As shown, the present invention realizes VLAN uplink N:1 aggregation and downlink 1:N conversion device, comprising:

[0037] (1) configuration unit, for adding user port and uplink port simultaneously in the service VLAN of VLAN uplink N: 1 aggregation; Establish entrance VLAN mapping relation table, uplink port mapping relation table and export VLAN mapping relation table;

[0038] (2) Up...

Abstract

The invention discloses a method and a device for realizing VLAN (Virtual Local Area Network) convergence and conversion in an EPON (Ethernet Passive Optical Network). The method comprises the steps of: adding each user port and upper interface in a VLAN service for VLAN uplink N:1 converging simultaneously; establishing an entry VLAN mapping relation table and an exit VLAN mapping relation table, related to each user port, and an upper interface mapping relation table related to the upper interface; and carrying out uplink N:1 convergence processing and downlink 1:N conversion processing according to the mapping relation tables. The invention realizes the support for VLAN uplink N:1 convergence and downlink 1:N conversion function for an ONU (Optical Network Unit), and the VLAN conversion among different user ports are mutually independent and free from interference; the user VLAN of different user ports can be converted into the same VLAN service; and one user port can have multiplegroups of VLAN conversion. The invention supports 1:1 VLAN conversion and N:1 VLAN conversion simultaneously, reduces cost of development, and increases performance price ratio.

Description

[technical field] [0001] The present invention relates to the field of EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network), in particular to the technical field of VLAN (Virtual Local Area Network, Virtual Local Area Network) conversion processing in Gigabit EPON. [Background technique] [0002] In the early access network based on EPON technology, the service requirements were simple, and it was not necessary to implement VLAN upstream N:1 convergence and VLAN downstream 1:N conversion functions on the ONU (Optical Network Unit). The continuous development and wide application of technology requires complex and intelligent ONU functions. The newly developed ONU needs to support VLAN upstream N:1 aggregation and VLAN downstream 1:N conversion, where N can be called user VLAN, and 1 can be called It is business VLAN. [0003] For VLAN uplink N:1 aggregation, it refers to converting different user VLANs received by a single or multiple user ports into th...
