Problems solved by technology

[0010] The main purpose of the present invention is to solve the problem that the flexible QinQ based on the OLT interface in the existing PON system cannot be specifically positioned to the relevant ONU, so that the range of CVLANs that can be used by different ONUs under the OLT interface is also limited; and the flexible QinQ based on the ONU interface in the PON system The scale of the number of ONUs under the OLT interface is easily limited by the resources of the entire system. A flexible QinQ implementation method in the passive optical network system is proposed. Under the OLT interface, the ONU can be located and the ONU’s capacity is expanded. Quantity scale

Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] A method for implementing flexible QinQ in a PON system, the specific process of the method is as follows figure 2 as shown,

[0029] S11, divide the ONU under the OLT interface in the PON system into a plurality of ONU groups;

[0030] S12, adding the first SVLAN identifier of the same group identifier in the message sent to the OLT by each ONU group, and the first SVLAN identifier of each ONU group is different from each other;

[0031] S13. The OLT modifies the group identifier first SVLAN identifier in the user message to a corresponding service identifier second SVLAN identifier.

[0032] Among them, the ONUs under the OLT interface in the ...

Abstract

The present invention discloses a method and an apparatus for implementing the flexible QinQ in a passive optical network (PON) system. The method comprises: dividing optical network units (ONUs) connected to interfaces of an optical line terminal (OLT) in a PON system into multiple ONU groups (S11); adding the first stack virtual local area network (SVLAN) identifier as the same group identifier in messages sent to the OLT by each ONU group, wherein the first SVLAN identifier of each ONU group is different (S12); changing the first SVLAN identifier as the group identifier in user messages to a corresponding second SVLAN identifier as the service identifier by the OLT (S13), thereby implementing the flexible QinQ technology based on the ONU groups, increasing the amount and scale of the ONU, and improving the service capacity of the system.

Description

technical field [0001] The invention relates to a method and a device for realizing QinQ services in a broadband access network system, in particular to a method for realizing flexible QinQ services in a PON (Passive Optical Network, Passive Optical Network) system and related devices. Background technique [0002] The flexible QinQ function is the function of adding different outer layer SVLAN (StackVLAN, stack virtual local area network) tags before the user's original packet VLAN (virtual local area network) TAG (label) based on different service data flows, see the attached figure 1 ,include: [0003] (1) According to different CVLAN (CustomerVLAN, user virtual local area network) ranges in the user data flow, put on different outer layer SVLAN labels; [0004] (2) According to different Ethernet protocol types in the user data stream, such as PPPOE / IPOE / ARP, put different outer layer SVLAN labels; [0005] (3) According to the priority of the user data flow, label dif...
