Description

一种配置数据分发方法及装置 技术领域
本发明涉及通讯技术领域，特别是涉及一种配置数据分发方法及装置。
背景技术
在无源光网络的G-PON(Gigabit-capable Passive Optical Network，千兆无源光网络设备)/EPON(Ethernet Passive Optical Network，基于以太网的无源光网络设备)以及其他PON(Passive Optical Network，无源光网络)运行网络(简称xPON网络)中，常见组网系统如图1所示。该系统由OLT(optical line terminal，光线路终端)、ODN(Optical Distribution Network，光分配网络)和若干个ONU(Optical Network Unit，光网络单元)组成：OLT作为中心局端设备通过SNI(Service Node Interface，业务节点接口)实现业务向上层设备的转发，并通过ODN网络连接汇聚多个ONU设备，ONU设备通过UNI完成用户业务的最终接入，从而实现多种业务传输和配置管理等功能。xPON网络作为“点对多点”的拓扑结构：从OLT到ONU的传输方向为下行方向，下行方向采用广播方式发送数据，由ONU根据数据标识判断数据是否有效并决定接收或丢弃；从ONU到OLT的传输方向为上行方向，上行方向根据机制不同可以采用TDM(Time Division Multiplexing，时分复用方式)或WDM(Wavelength Division Multiplexing，波分复用方式)：在时分复用方式中，上行方向采用TDM，ONU必须根据OLT分配的上行带宽时隙来发送上行突发(Burst)信号；在波分复用方式中，ONU上行数据承载于特定的工作波长中。在xPON网络中，OLT的单个PON口通过唯一标识来区分并管理每个ONU：EPON网络中，MAC(Medium Access Control，媒质访问控制)地址是ONU的物理标识；在GPON网络中，SN(Serial Number，序列号)号是ONU的物理标识。通过物理标识完成ONU在PON系统上的注册，并通过MAC地址、序列号(SN)、逻辑ONU标识(LOID--Logical ONU Identifier)以及密码(PW)等完成逻辑开通认证；在其他的PToMP网络中也会使用类似的标识，设置为OLT区分和管理每个ONU。
OLT管理ONU可以通过其内置的OAM(Operation Administration and Maintenance，操作管理维护)通道来实现，不同xPON实现分别采用不同的OAM协议，如EPON系统采用的扩展OAM协议，以及GPON系统采用的OMCI(ONU Management and Control Interface，光网络单元管理控制接口)协议。通过上述协议将ONU业务配置下发到ONU本地生效，并保证ONU的业务转发，因此ONU除完成基本的物理线路功能外，还需要按要求实现二层或三层业务转化的功能以及与业务相关 的其他功能。
xPON系统设备中根据ONU的用户端口数量及其业务形态，可以分为多种FTTB(Fiber to The Building，光纤到楼)、FTTH(Fiber to the Home，光纤到户)等多种使用场景。其中FTTH场景是目前应用最为广泛的场景，一般通过SFU(单住户单元)下接家庭网关来接入家庭用户的多种业务，如，宽带上网、语音和IPTV(Interactive Personality TV，交互式网络电视)等，也可以直接接入PON上行的HGU(Home Gateway Unit，家庭网关)。但上述两种方式中家庭网关由于远端部署，且需要实现相关用户接入，业务标识与转换等功能，使其存在成本高、维护困难的缺点。针对此问题，可以将家庭网关的核心功能放在xPON OLT设备上来实现，这样用户家庭内的设备变成了只有线路功能的简单设备，以实现降低用户侧家庭网关设备的技术复杂度以及维护的工作量，这种技术被称为虚拟驻地网关，即VRG(virtual remote gateway，虚拟家庭网关)技术。该技术可以有效的降低网络的维护成本，使得同一台GPON OLT设备下就有可能同时存在传统的PON上行家庭网关和只有线路功能的两种不同的家庭接入设备，然而,目前现有技术无法对以上场景提出对两种家庭接入设备进行统一配置管理，可见，一种对不同网关进行统一配置管理方法方案有待被提出。

具体实施方式
为了解决现有技术中并不存在对两种家庭网关接入设备的统一配置管理方案的问题，本发明提供了一种配置数据分发方法及装置，以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
实施例1
本实施例提供了一种配置数据分发方法，该方法可由OLT来执行，该方法主要用于实现区分属于不同网关的配置数据的封装方式，并将其下发至所属网关的目的。图2是本发明实施例1的配置数据分发方法的流程图，如图2所示，该方法具体可以包括如下处理：
步骤101：根据ONU的标识以及预先设置的ONU的标识与ONU的配置数据的封装方式的对应关系确定配置数据的封装方式；
在该步骤101中，ONU的标识可以包括，ONU上线是上报的注册标识、其他可以标识该ONU的认证数据或ONU的类型。
步骤102：按照确定出的封装方式封装配置数据，根据ONU的封装方式或ONU的标识将封装后的配置数据分发至对应的网关。
在该步骤102之后，在判断配置数据对应虚拟家庭网关的情况下，判断配置数据是业务相关数据还是线路相关数据，如果是业务相关数据，则将业务相关数据分发到OLT侧的网关虚拟单元并生效，如果是线路相关数据，则通过扩展OAM/OMCI通道将线路相关数据发送至远端线路单元。
其中，在步骤101的基础上，为了在配置数据量较大时能够更加高效的确定出配置数据的封装方式，可选的，上述步骤101，可以按照如下具体方式来进行：
根据ONU的标识，确定封装配置数据所需使用的预先设置用户数据配置模板，用户数据配置模板中规定了数据的封装方式；此处，预先设置用户配置模板的具体步骤为：
在根据光网络单元ONU的标识确定配置数据的封装方式之前，根据ONU使用的网关的种类创建与网关的种类对应的用户数据配置模板，以及设置用户数据配置模板与ONU标识的对应关系。
基于预先设置的用户数据配置模板，按照确定出的封装方式封装配置数据，根据ONU的封装方式或ONU的标识将封装后的配置数据分发至对应的网关，具体可以包括：
在当前实体家庭网关或虚拟家庭网关对应的ONU在线时，根据配置数据的封装方式判断配置数据对应的是实体家庭网关或虚拟家庭网关；
在当前实体家庭网关或虚拟家庭网关对应的ONU新上线时，根据ONU上报的标识判断配置数据对应的是实体家庭网关或虚拟家庭网关；
在判断配置数据对应虚拟家庭网关的情况下，按照光线路终端OLT上的虚拟家庭网关模块和用户家庭中的线路单元的功能划分分发配置数据给虚拟家庭网关模块和用户家庭中的线路单元；
在判断配置数据对应实体家庭网关的情况下，将业务配置数据通过OAM/OMCI通道发送至实体家庭网关上。
本实施例提供的方法通过建立设备终端的标识与用户数据配置模板的对应关系，可以在xPON现网应用中实现对HGU/VRG的便捷管理以及业务的自动开通，同时可以忽略用户的具体配置而自动实现配置数据分发，业务恢复等功能。在减少用户侧终端设备业务实现复杂度、降低其运维成本的同时，既符合xPON网络运营者的运维需求，也满足了终端用户的需求。
实施例2
本实施例提供了一种在无源光网络系统下基于传统家庭网关和虚拟家庭网关智能接入两种设备混合组网情况下的一种集中统一配置和管理的实现方法。其中，将VRG的终端的标识(包括但不限于EPON的MAC还是GPON的SN，或者是PW(password，密码)/LOID(逻辑ID)以及其他可以唯一标识ONU等的认证相关参数)与不同的用户数据配置模板进行绑定，在HGU/VRG的终端初次上线并建立管理通道后，OLT根据终端类型标识自动调用不同的用户数据配置模板，从而实现在一个xPON网络中自动管理和开通不同HGU/VRG业务的方法。
本实施例以在xPON网络中按照本发明所提出的配置数据分发方法的一种实施范例，其中，根据实际业务需求在OLT上完成相应数据数据的配置，OLT与终端设备之间通过扩展OAM/OMCI通道完成数据配置与管理，图3是本发明实施例2的配置数据分发方法的流程图，如图3所示，该方法具体可以包括如下步骤：
S201：OLT针对使用传统的家庭网关，即实体家庭网关和虚拟驻地网关，虚拟家庭网关两种用户分别创建一个用户数据配置模板，用以区分两种不同的用户设备，其中，不同的用户数据配置模板封装的数据不同。
S202：当ONU上线时，会上报其注册标识以及类型，OLT根据ONU注册标识(或其他可以标识该ONU的认证数据)以及其类型建立与不同用户数据配置模板的对应关系。
S203：OLT根据具体ONU类型将业务配置数据引用不同的用户数据配置模板进行扩展OAM/OMCI组包。配置的具体业务数据可以忽略两种不同设备的差别，按照正常的传统家庭网关需要的业务数据来进行配置，包括但不限于对应的ONU ID号、LLID(Logical link identify，逻辑链路标识)或者Gem-Port、DBA(Dynamic Bandwidth Allocation，动态带宽分配)、VLAN(Virtual Local Area Network，虚拟局域网)等业务通道相关参数；还有对应终端设备的接口速率、工作模式等端口物理参数，以及其它相关参数。
S204：当实体家庭网关或者虚拟家庭网关对应的远端线路单元在线时，直接将相关配置数据分发，否则就保存在OLT上，待上述设备上线后下发。
配置数据的下发需根据用户数据配置模板判断发到实体家庭网关或者在xPON OLT设备上的虚拟家庭网关模块以及远端线路单元。对于虚拟家庭网关的配置数据，可以按照功能模块划分将业务开通需要的配置数据分别分发到OLT上虚拟驻地网关模块和在用户家庭中的线路单元，统一采用和分发到实体家庭网关单元一样的扩展OAM帧/OMCI帧。
S205：当ONU上线时，OLT根据ONU标识及类型判断新上线ONU是否属于虚拟家庭网关，并进行相应的处理。若判断新上线ONU非虚拟家庭网关，则引用对应用户数据配置模板将所有数据通过扩展OAM/OMCI通道分发到实体家庭网关上，并在实体家庭网管上生效。
S206：若判断新上线ONU属于虚拟家庭网关，则引用对应用户数据配置模板，并根据配置数据是否为线路数据判断业务数据的分发位置。
S207：若配置数据为业务相关数据(包括但不限于业务标记、业务转发、路由以及其他相关配置)，则将业务相关数据分发到OLT侧的网关虚拟单元并生效。
S208：若配置数据为线路相关数据，则通过扩展OAM/OMCI通道分发到远端线路单元，并在远端线路单元上生效，并最终完成虚拟驻地网关的业务分发。
如果对应虚拟家庭网关的线路单元关电，则通过xPON OLT内部消息通知对应的虚拟家庭网关模块停止工作；当xPON OLT检测到线路单元上电后，重新将该虚拟家庭网关的配置按照上述方法分发到虚拟家庭网关模块和远端的线路单元，确保终端用户的业务及时恢复；当xPON OLT检测到实体家庭网关上电，重新将该实体家庭网关的配置按照上述方法分发到实体家庭网关，确保业务及时恢复。
实施例3
如图1所示的系统的原理图参见图1所示，本实施例所提供的系统同样包括OLT100、ODN200、HGU300、VRGolt400、VRGonu500，其中，OLT100，设置为根据实际需要生成相关的业务配置数据以及终端设备(HGU/VRG)标识/类型与用户数据配置模板的映射表，用于启动ONU的上线发现过程，在获取终端设备，即ONU的标识/类型后，根据映射关系控制相应HGU/VRG分别完成正确的数据配置过程。业务配置数据只与具体业务有关，而与ONU类型无关；
对于HGU300，业务配置数据根据其对应用户数据配置模板全部下发并在HGU300侧生效；对于VRG类型的ONU，业务配置数据根据其对应配置模板分为两部分，对于与线路无关的业务数据，分发至OLT100侧的虚拟的VRGolt400模块，对于与线路有关的数据，则分发给远程ONU侧的VRGonu500，并通过OLT侧虚拟驻地网关模块VRGolt400与远端线路终端VGRonu500共同实现对虚拟驻地网关的管理和 配置；
ODN200，设置为在OLT100对应PON端口下连接数量不等的ONU(包括不限于HGU300与VRGonu500)，作为OLT100和ONU之间直接的物理连接通道，可能由多个无源光物理器件及其联接光缆等组合而成；
HGU300，设置为承担接入终端设备到xPON网络的角色，接受OLT200的管理，并根据OLT200下发的配置实现本地的业务标记、转发、路由以及其他功能。
VRGolt400，虚拟驻地网关的OLT软件模块，接受OLT200的管理，并根据OLT分发配置，实现虚拟驻地网关的业务标记、转发以及路由等非线路配置功能。
VRGonu500，虚拟驻地网关的远端线路终端，是虚拟驻地网关的实体终端部分，位于ONU侧。接受OLT200的管理，并根据OLT分发配置，实现与线路相关的配置与功能。

可选的，上述装置40还可以包括：第二分发模块，设置为在根据ONU的封装方式或ONU的标识将封装后的配置数据分发至对应的网关之后，在判断配置数据对应虚拟家庭网关的情况下，判断配置数据是业务相关数据还是线路相关数据，如果是业务相关数据，则将业务相关数据分发到OLT侧的网关虚拟单元并生效，如果是线路相关数据，则通过扩展OAM/OMCI通道将线路相关数据发送至远端线路单元。
