虚拟局域网模式的配置方法、系统技术领域 Virtual LAN mode configuration method, system

本发明涉及吉比特无源光网络领域，特别是指一种虚拟局域网模式的配置方法、系统。背景技术 The present invention relates to the field of gigabit passive optical networks, and in particular to a method and system for configuring a virtual local area network mode. Background technique

GPON ( Gigabit-Capable PON , 吉比特无源光网络）是一种点到多点的光接入技术， GPON接入的网络架构如图 1所示。其中， OLT ( Optical Line Terminal,光线路终端）为 GPON局端设备； ONT( Optical Network Terminal, 光网络终端）为用户端设备； OLT与 ONT之间通过由无源分光器件组成的 ODN ( Optical Distribution Network, 光分布网）相连接； OMCC ( ONT管理控制通道）提供了 OLT对 ONT的管理和控制通道， U I为用户网络接口， SNI为业务节点接口，其中，实线代表业务通道，虚线代表 OMCI管理和控制通道。 GPON (Gigabit-Capable PON, Gigabit Passive Optical Network) is a point-to-multipoint optical access technology. The network architecture of GPON access is shown in Figure 1. The OLT (Optical Line Terminal) is a GPON central office device; the ONT (Optical Network Terminal) is a user equipment; and the OLT and the ONT pass an ODN (optical distribution) composed of passive optical splitting devices. Network, optical distribution network) connection; OMCC (ONT management control channel) provides management and control channels for OLT to ONT, UI is user network interface, SNI is service node interface, where solid line represents service channel, dotted line represents OMCI Manage and control channels.

现有技术中， G.984.4具体定义了 OMCI的通用机制以及相关的 ME(管理实体）等， OLT通过 OMCI对相关 ME进行配置，从而实现 ONT的远程配置和管理。 In the prior art, G.984.4 specifically defines the general mechanism of OMCI and related MEs (management entities). The OLT configures related MEs through OMCI to implement remote configuration and management of ONTs.

GPON ONT需要对报文进行 tag处理和 tag过滤的操作， G.984.4标准规定了 ONT中 VLAN ( Virtual Local Area Network, 虚拟局域网 )处理的操作流程（如图 2所示）， ANI (接入网络接口 )侧和 U I (用户网络接口 ) 侧分别进行 VLAN处理和过滤；以业务流的上行方向为例 , 从 U I侧分别经过 VLAN处理、 VLAN过滤、通过桥以后、再进行 VLAN过滤、 VLAN 处理、最后到达 ANI侧。根据这个流程标准中也定义了三个管理实体来对 VLAN进行操作，分别是 VLAN tagging filter data (后面简称 VLAN filter )、 VLAN tagging operation configuration data (后面简称 VLAN operation ), Extended VLAN tagging operation configuration data (后面简称 ex- VLAN operation ),其中由 VLAN filter实体来进行 Tag— filtering,由 VLAN operation 或者 ex- VLAN operation实体来进行 Tag— operation。 GPON ONT needs to perform tag processing and tag filtering on packets. The G.984.4 standard specifies the operation flow of VLAN (Virtual Local Area Network) processing in ONT (as shown in Figure 2), ANI (access network) VLAN processing and filtering are performed on the interface side and the UI (user network interface) side. The uplink direction of the service flow is taken as an example. After the VLAN processing, VLAN filtering, bridge pass, VLAN filtering, VLAN processing, and VLAN processing, Finally arrive at the ANI side. According to this process standard, three management entities are also defined to operate on VLANs, which are VLAN tagging filter data (hereinafter referred to as VLAN filter). VLAN tagging operation configuration data (hereinafter referred to as VLAN operation), extended VLAN tagging operation configuration data (hereinafter referred to as ex-VLAN operation), wherein the VLAN filter entity performs Tag-filtering, and the VLAN operation or ex-VLAN operation entity performs Tag. — operation.

OLT通过 OMCI配置上述的 VLAN相关的管理实体来实现对 ONT的 VLAN 配置，但现有技术的配置方法是对上述实体进行组合配置才能得到完整的 VLAN配置模型，实施难度较大。发明内容 The OLT configures the VLAN-related management entity to implement the VLAN configuration of the ONT through the OMCI. However, the configuration method of the prior art is to combine the foregoing entities to obtain a complete VLAN configuration model, which is difficult to implement. Summary of the invention
