下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互任意组合。 本发明实施例的虚接口建立在桥接口基础上， 主要用于用户侧多业务接 入场景配置，根据不同的业务承载方法进行定义，每个虚接口承载一个业务。 虚接口和桥接口之间存在多对一的关系。 根据 PON***中宽带接入网实际组网需求，一个物理接口（以太网无源 光网络（ Ethernet PON , ΕΡΟΝ ) /千兆无源光网络（ Gigabit PON , GPON )的 ONU ) 下的虚接口数最大定义为 8个（可视实际需要进行扩展） 。 Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other. The virtual interface of the embodiment of the present invention is based on the bridge interface, and is mainly used for the configuration of the multi-service access scenario on the user side, and is defined according to different service bearer methods, and each virtual interface carries one service. There is a many-to-one relationship between the virtual interface and the bridge interface. According to the actual networking requirements of the broadband access network in the PON system, the number of virtual interfaces under one physical interface (Ethernet Passive Optical Network (Ethernet PON, ΕΡΟΝ) / Gigabit PON (GPON) ONU) The maximum is defined as 8 (expanded as needed).

Indicates that the dual group includes a virtual interface identifier and a bridge interface identifier. The virtual interface identifier (ID) includes: the chassis number (Shelf), the slot number (Cardid), the OLT number, the ONU number, and the virtual interface number. The virtual interface identifier can use the following representation: Shelf Cardid OLT number ONU number virtual interface number

(4bit) (5bit) (3bit) (8bit) (8bit) The above representation can also be used to indicate the bridge interface identifier:
Figure imgf000008_0001
此时可通过 lbit的标志位来区别该标识是虚接口标识还是桥接口标识。 桥接口号通过 EPON的逻辑链路标识 （Logic Link Identification, LLID )或 GPON 的 GPON 封装方法端口 （ GPON Encapsulation Method PORT , GEMPORT )来表示。 上述表示方法还可以用来表示 EPON或 GPON***中的 OLT标识：  At this time, the lbit flag can be used to distinguish whether the identifier is a virtual interface identifier or a bridge interface identifier. The bridge interface number is represented by EPON's Logical Link Identification (LLID) or GPON's GPON Encapsulation Method PORT (GEMPORT). The above representation can also be used to represent the OLT identity in an EPON or GPON system:
Shelf(4bit) Cardid(8bit) OLT编号（8bit) 或者用来表示 EPON或 GPON***中的 ONU标识: Shelf (4bit) Cardid (8bit) OLT number (8bit) or used to indicate the ONU identifier in an EPON or GPON system:

Figure imgf000008_0002
可选地， 在上述标识中还可增加 4bit的类型字段， 该标识共 32位 c Alternatively, the marker may also be an increase in the 4bit type field, which identifies a total of 32 bits c
在本实施例中， 虚接口信息包括虚接口标识和基本业务配置信息， 其中 基本业务配置信息包括： 用户虚拟局域网 （Virtual Local Area Network, VLAN )信息、 以及用户 VLAN信息被转换后的 VLAN信息。此外， 可选地， 还可包括以下内容中的一种或几种： 桥接口号（包括 LLID或 GEMPORT ) 、 用户优先级、 用户 文协议类型、 以及外层 VLAN。 未加标签标识和用户虚 拟标识（vid )二选一。 可釆用以下方式表达： service-port portid [Hid llidid gemport portid}] user-vlan {untagged (常 量 ) I user-vid (更量 ) } [user-dotlq priority] [user-etype PPPOE\ IPOE] vlan vid [svlan svid] 其中： 粗体字表示关键字或常量， 非粗体表示内容或变量， 口表示可选， {}表示二选一， T 表示 "或者" 。 表达式中的 service-port为虚接口标识， Hid为還辑链路标识， gemport 为通用封装模式， user-vlan表示用户 VLAN信息即用户报文中携带的 VLAN, uesr-dotl q表示用户优先级， user-etype表示用户报文协议类型 （可以是以太 网上的点对点协议 ( Point-to-Point Protocol over Ethernet, PPPOE )或者是以 太网上的网际协议 ( IP over Ethernet, IPOE ) ) , vlan表示 user-vlan被转换 后的 VLAN (如果未经转换则 vlan=user vlan ) , svlan表示可选择增加的外 层 VLAN, 透传时不携带。 通过上述表达式， 可以看出虚接口与桥接口之间有一定的关联关系。 即 在设置虚接口与业务的对应关系时， 已指明了虚接口所关联的桥接口。 由于 虚接口和桥接口之间存在多对一的关系， 因此由一个虚接口可以查询到其关 联的唯一的桥接口。 当有多个业务需要通过桥接口来实现时， 可以设置与一 个桥接口关联的多个虚接口， 即由一个桥接口可以查询到其所关联的多个虚 接口。 因此在***实现的时候需要维护一个桥接口到虚接口之间 1 :N的映射 关系。 In this embodiment, the virtual interface information includes a virtual interface identifier and basic service configuration information, where the basic service configuration information includes: a virtual local area network (VLAN) information, and VLAN information after the user VLAN information is converted. In addition, optionally, one or more of the following may be included: a bridge interface number (including LLID or GEMPORT), a user priority, a user text protocol type, and an outer VLAN. The untagged identifier and the user virtual identifier (vid) are selected one by one. It can be expressed in the following way: service-port portid [Hid llidid gemport portid}] user-vlan {untagged (constant) I user-vid (more) } [user-dotlq priority] [user-etype PPPOE\ IPOE] vlan Vid [svlan svid] where: bold type indicates a keyword or constant, non-bold indicates content or variable, port indicates optional, {} indicates two choices, and T indicates "or". The service-port in the expression is the virtual interface identifier, Hid is the link identifier, gemport In the general encapsulation mode, user-vlan indicates that the user VLAN information is the VLAN carried in the user packet, uesr-dotl q indicates the user priority, and user-etype indicates the user packet protocol type (can be a point-to-point protocol on the Ethernet (Point- To-Point Protocol over Ethernet (PPPOE) or Internet over Ethernet (IPOE), vlan indicates the VLAN after the user-vlan is converted (vlan=user vlan if not converted), svlan indicates Select the added outer VLAN and do not carry it when transparent. Through the above expression, it can be seen that there is a certain relationship between the virtual interface and the bridge interface. That is, when the mapping between the virtual interface and the service is set, the bridge interface associated with the virtual interface is specified. Because of the many-to-one relationship between the virtual interface and the bridge interface, a virtual interface can query its associated unique bridge interface. When multiple services need to be implemented through the bridge interface, multiple virtual interfaces associated with one bridge interface can be set, that is, one bridge interface can query multiple virtual interfaces associated with it. Therefore, when the system is implemented, it is necessary to maintain a 1:N mapping relationship between a bridge interface and a virtual interface.

工业实用性 本发明利用基于虚接口的配置方法，简化并统一了 PON***中宽带业务 的配置。 同时， 虚接口在上层业务和底层硬件实现之间起到了中间适配层的 作用， 在一定程度上实现上层业务软件***和物理层实现的隔离， 消除了软 件***模块间的耦合关系， 有利于软件***的模块化和平台化。 Industrial Applicability The present invention simplifies and unifies the configuration of broadband services in a PON system by using a virtual interface-based configuration method. At the same time, the virtual interface plays an intermediate adaptation layer between the upper layer service and the underlying hardware implementation, and achieves the isolation of the upper layer business software system and the physical layer implementation to a certain extent, thereby eliminating the coupling relationship between the software system modules, which is beneficial to Modularity and platformization of software systems.
