Embodiment Construction

[0044] The core of the method of the present invention is: according to the access user type, the Ethernet type of the inner layer VLAN of the double-layer VLAN Ethernet message is encapsulated into different values, and is transmitted to the access node through the uplink port of the access node, The access node directly determines the access user type according to the Ethernet type of the inner VLAN of the received message, and the access node forwards the message according to the access user type.

[0045] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0046] The present invention first needs to set different values ​​of the Ethernet type of the inner layer VLAN of the message according to different types of access users, that is, the Ethernet type of the inner layer VLAN of the message bears the identification information of the type of access user.

[0047] The Ethernet type of ...

Abstract

The invention relates to a method for realizing two-layer VLAN Ethernet report transfer in the access network and relative access node. Wherein, it is characterized in that: according to the user type, packing the Ethernet type pf inner VLAN of two-layer VLAN Ethernet report into different values, to be transmitted to the access node by the ascending port of access node; the access node according to said Ethernet type fixes the type of access user and transfers report. The invention can avoid access node to search for the user type according to the S-VLAN, to fix the user type quickly and accurately. Therefore, it can simplify the report transfer and improve the transfer efficiency of node report.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and an access node for an access network to realize double-layer VLAN Ethernet message forwarding. Background technique [0002] In WT101 of the DSL Forum (Digital Subscriber Line Forum), in order to improve the scalability of the network scale, the double-layer VLAN (virtual local area network) defined by IEEE 802.1ad, that is, the VLAN Stack (stack), is used as a gateway for accessing enterprise and residential users. The inner VLAN is called user VLAN or C-VLAN, and the outer VLAN is called service VLAN or S-VLAN. [0003] IEEE 802.1ad stipulates that the inner VLAN uses the same EtherType (Ethernet type) value 0x8100 as IEEE 802.1Q as the symbol of C-VLAN, and the outer VLAN adopts an EtherType value different from the inner VLAN to distinguish it from C-VLAN. . The specific value of the outer VLAN has not been determined yet. [0004] According to t...
