本发明涉及无源光网络（PON, Passive Optical Network )技术， 特别 是指一种无源光网络业务的配置方法及装置。 背景技术
PON技术目前已经是光接入网领域的首选技术， 其在接入速率、 带宽 效率和分光比、 全业务承载能力以及安全性方面都具有明显优势。 PON技 术还分为以太网无源光网络 ( EPON , Ethernet Passive Optical Network )和 千兆无源光网络 ( GPON, Gigabit-Capable Passive Optical Network ), EPON 技术由电气和电子工程师协会 ( IEEE, Institute of Electrical and Electronics Engineers ) 802.3研究项目中一第一英里以太网（ EFM, Ethernet for the First Mile )工作组进行标准化； GPON技术是由国际电信联盟远程通信标准化组 ( ITU-T , International Telecommunication Union Telecommunication Standardization Sector )提出并标准化， 最终形成了 G.984.X系列标准。
无论是 EPON技术还是 GPON技术，宽带接入业务的种类都基本相同， 因此， PON业务配置的步骤大体相同。 PON系统目前可提供的业务种类包 括 Internet业务、 VoIP ( Voice over Internet Protocol )业务、 电路仿真业务 ( CES , Circuit Emulation Service )、数字用户线路（ xDSL, x Digital Subscriber Line ) 业务、 视频业务等， PON 业务配置的过程主要是依据各自标准逐一 西己 。
从 PON 层面上来看， 一条端到端业务的配置起始点是光网络单元 ( ONU, Optical Network Unit )物理终端点用户端口 （ ONU PPTP(Physical Path Point) UNI(User Network Interface) ), 终止点是光线路终端 （OLT, Optical Line Terminal ) 的上联虚端口 （ Virtual Port ), PON业务配置的过程 就是在两点间配置一系列业务属性数据。 业务属性数据主要包括业务划分、 业务服务质量（QoS, Quality of Service ), 具体业务的详细配置参数等方面 内容。 所述业务划分如虚拟局域网 （VLAN, Virtual Local Area Network ), 优先级、 以太网类型等； 所述 QoS如流量限速、 优先级队列映射等； 所述 具体业务的详细配置参数如 VoIP语音相关详细参数等。
目前， 存在的问题是： 由于 EPON技术和 GPON技术实际是不同的， PON业务配置的过程也是不同的， 即便是同一种 PON技术， 不同设备厂商 提供的 PON业务配置的方式和过程也是千差万别的。 另外， 一个更严重的 问题是各设备厂商所提供的 PON业务配置过程过于复杂， OLT与 ONU的 PON业务配置是分离的。 发明内容
有鉴于此， 本发明的主要目的在于提供一种无源光网络业务的配置方 法及装置， 简化与统一 PON业务配置。
为解决上述技术问题， 本发明的技术方案是这样实现的：
一种无源光网络业务的配置方法， 包括： 进行无源光网络（PON ) 业 务配置时， 根据业务流的业务信息使用设置的全局配置模板作用于业务配 置点。
所述全局配置模板至少包括： 光网络单元物理终端点用户端口 （ONU PPTP UNI ) 系列业务模板和服务质量（QoS ) 系列模板； 所述业务配置点 包括 ONU PPTP UNI、光网络单元（ ONU )的逻辑端口和光线路终端（ OLT ) 的上联虚端口； 该方法具体包括：根据业务流的类型使用对应的 ONU PPTP UNI业务模板作用于 ONU PPTP UNI; 根据业务流的业务信息使用对应的 QoS模板作用于 ONU的逻辑端口和 OLT的上联虚端口。
该方法进一步包括： 根据业务流的业务信息及承载业务的 PON系统的 网络环境确定业务划分与转发后， 直接在 OLT端和 ONU端分别配置业务 划分与转发的相关业务属性数据； 或者， 所述全局配置模板进一步包括： 业务划分与转发系列模板； 该方法进一步包括： 根据业务流的业务信息及 承载业务的 PON系统的网络环境， 使用对应的业务划分与转发模板作用于 业务流关联的 OLT端和 ONU端。
该方法进一步包括： 为业务流设置名称来标识所述业务流。
所述进行 PON业务配置之前， 进一步包括： 根据将存在的各种业务流 设置全局配置模板， 并对设置好的全局配置模板进行存储。

所述配置单元进一步包括： 划分与转发配置单元；
所述划分与转发配置单元用于根据业务流的业务信息及承载业务的 PON系统的网络环境确定业务划分与转发后， 直接在 OLT端和 ONU端分 别配置业务划分与转发的相关业务属性数据； 或者，
所述全局配置模板进一步包括业务划分与转发系列模板， 所述划分与 转发配置单元用于根据业务流的业务信息及承载业务的 PON系统的网络环 境， 使用对应的业务划分与转发模板作用于业务流关联的 OLT端和 ONU 端。

所述装置进一步包括模板设置单元， 用于根据将存在的各种业务流设 置全局配置模板， 并将设置好的全局配置模板存储于模板存储单元。
本发明提供了一种基于业务流思想进行 PON业务配置的方案， 简单易 行。 与现有的 PON业务配置相比较， 本发明提出了端到端完整业务流的概 念,基于业务流进行 PON业务配置的过程主要依赖于设置的全局配置模板； 通过全局配置模板明确了业务流所具有的关键特性以及属性， 统一了不同 PON技术的 PON业务配置， 同时也最大程度地简化了 PON业务配置的操 作。 本发明方案是一个非常好的业务配置模型， 充分遵照了运营商运营理 念， 屏蔽了与标准相关的底层实现， 简化操作的同时又不失业务属性数据 的全面性和灵活性。
"ONU上的 QoS" 与 "OLT上的 QoS" 充分体现了业务流的全面性、 及不同场景的适用性。 另外， "ONU上的业务划分与转发" 与 "OLT上的 业务划分与转发" 充分体现了业务流的灵活性。 附图说明

本发明中， 进行 PON业务配置时， 根据业务流的业务信息使用设置的 全局配置模板作用于业务配置点。
所述业务配置点包括 ONU PPTP UNI、 ONU的逻辑端口和 OLT的上联 虚端口。 ONU PPTP UNI与 ONU的逻辑端口连接， ONU的逻辑端口与 OLT 的上联虚端口连接， 这样就构成了一条经过 ONU端和 OLT端的完整的业 务流。 ONU PPTP UNI与 ONU的逻辑端口是 n:n的关系， ONU的逻辑端口 与 OLT的上联虚端口是 1 :1或者 n:l的关系。 所述 ONU的逻辑端口可以为 GPON的 GPON封装模式端口 （GEM PORT )或 EPON的逻辑链路标识 ( LLID , Logical Link Identifier )端口。
所述全局配置模板至少包括 ONU PPTP UNI系列业务模板和 QoS系列 模板， 进行 PON业务配置时， 具体地， 根据业务流的类型使用对应的 ONU PPTP UNI业务模板作用于 ONU PPTP UNI; 根据业务流的业务信息使用对 应的 QoS模板作用于 ONU的逻辑端口和 OLT的上联虚端口， 这样便完成 了基本的 PON业务配置。 所述 ONU PPTP UNI业务模板或 QoS模板可以 预先设置； 也可以在进行 PON业务配置时， 根据当前需要进行的 PON业 务配置进行设置， 相应地添加至 ONU PPTP UNI业务系列模板或 QoS系列 模板中， 以便以后出现相同或相近情况的 PON业务配置时， 能够再次使用 相应模板， 使得相同的配置信息能够重复使用， 避免了重复配置。
所述全局配置模板可以进一步包括业务划分与转发系列模板， 根据业 务流的业务信息及承载业务的 PON系统的网络环境， 使用对应的业务划分 与转发模板作用于业务流关联的 OLT端和 ONU端。 业务划分与转发模板 可以预先设置； 也可以在进行 PON业务配置时，根据当前需要进行的 PON 业务配置进行设置， 相应地添加至业务划分与转发系列模板中， 以便以后 出现相同或相近情况的 PON业务配置时， 能够再次使用相应模板， 使得相 同的配置信息能够重复使用， 避免了重复配置。
所述全局配置模板不包括业务划分与转发系列模板时， 根据业务流的 业务信息及承载业务的 PON系统的网络环境确定业务划分与转发后， 直接 在 OLT端和 ONU端分别配置业务划分与转发的相关业务属性数据。
PON业务配置的顺序是非常灵活的， 可以从 ONU开始， 然后到 OLT; 也可以从 OLT开始， 然后到 ONU。
图 1为本发明中实现 PON业务配置的模型结构示意图， 如图 1所示， 全局配置模板至少包括： ONU PPTP UNI系列业务模板和 QoS系列模板。
ONU PPTP UNI系列业务模板是根据 ONU PPTP UNI的类型设置的不 同的业务模板， ONU PPTP UNI的类型包括以太网用户端口（ Ethernet UNI )、 模拟电话业务用户端口（POTS UNI ),数字用户线路用户端口（xDSL UNI )、 电路仿真业务用户端口 （CES UNI )、 视频业务用户端口 （ Video UNI )等。 由于不同类型的 ONU PPTP UNI的 PON业务配置存在很大区另' j ,有些类型 的 ONU PPTP UNI的 PON业务配置相当复杂， 因此， 为简化和减少重复配 置， 可以针对不同类型的 ONU PPTP UNI的业务属性数据归纳和总结出专 用的 ONU PPTP UNI业务模板，组成 ONU PPTP UNI系列业务模板。例如， ONU PPTP UNI系列业务模板包括如下 ONU PPTP UNI业务模板： CES业 务模板、 基于会话启动协议（SIP, Session Initiation Protocol )的 VoIP业务 模板、基于 H.248协议的 VoIP业务模板、 xDSL业务模板等。 ONU PPTP UNI 的类型应与该 ONU PPTP UNI 7 载的业务流的类型相对应，例如， xDSL业 务流需要 xDSL UNI来承， CES业务流需要 CES UNI来承载， 这样， 进行 PON业务配置时， 通过业务流的类型便可确定 ONU PPTP UNI的类型 , 从 而使用相应的 ONU PPTP UNI业务模板。 ONU PPTP UNI业务模板作用于 相应 ONU PPTP UNL
QoS系列模板是描述业务流传输过程中用来保证 QoS的数据模板， 针 对相同的 QoS参数归纳和总结出具有一定通用性的 QoS模板。 QoS系列模 板包括一系列以 QoS参数为内容的 QoS模板， 如带宽分配模板、 业务流限 速模板、 队列优先级映射模板等。 QoS模板分别作用于 OLT的上联虚端口 和 ONU的逻辑端口。 进行 PON业务配置时， 根据业务流的业务信息便可 确定所需的 QoS参数， 从而使用相应的 QoS模板。
全局配置模板可以进一步包括业务划分与转发系列模板， 业务划分与 转发系列模板用来描述业务的划分及转发机制， 具体是依据以太网 ( Ethernet ) 中的 IEEE 802.1Q标签帧格式来划分业务， 并依据承载业务的 PON系统的网络环境确定业务的转发机制。 例如， 可以按照 VLAN、 优先 级、 VLAN+优先级、以太网类型、 VLAN+以太网类型、标签协议标识（ TPID , Tag Protocol Identifier )等方式来划分业务。 又如， 业务划分与转发系列模 板中有关转发的内容可以为用户 VLAN ( CVLAN , Customer VLAN )、 堆叠 VLAN ( SVLAN, Stack VLAN )、 VLAN转换、 优先级处理方式等属性。 业 务划分与转发模板分别作用于业务流关联的 OLT端和 ONU端。
全局配置模板设置好以后， 便可以在进行 PON业务配置时， 在全局配 置模板中选择适用的模板进行 PON业务配置， 这样能够大大简化 PON业 务配置， 并且简单易行。
图 2为本发明中实现 PON业务配置的流程示意图， 如图 2所示， 实现 PON业务配置的处理过程包括以下步骤：
步骤 201 : 模板设置单元根据可能存在的各种业务流设置全局配置模 板， 并将设置好的全局配置模板存储于模板存储单元。
所述全局配置模板至少包括 ONU PPTP UNI系列业务模板和 QoS系列 模板， 模板设置单元可以根据各种业务流的业务信息进行设置， 也可以根 据配置管理员输入的信息进行设置； 所述全局配置模板还可以进一步包括 业务划分与转发系列模板， 可以根据各种业务流的业务信息及承载业务的 PON系统的网络环境进行设置， 也可以才艮据配置管理员输入的信息进行设 置。
步骤 202: 需要创建端到端的业务流时， 即需要进行 PON业务配置时， 配置单元确定业务流的业务信息， 该业务信息中包括业务流的类型， 如上 网业务、 VoIP语音业务、 xDSL业务、 IPTV视频业务等。 业务流的业务信 息是指与业务流相关的业务属性数据， 如类型、 QoS要求、 业务划分等。
配置单元还可以进一步为业务流设置名称来标识该业务流， 以使该业 务流能够区分于其他业务流。
步骤 203~步骤 205: 配置单元中的 UNI配置单元根据业务流的类型选 择业务流所要关联的 ONU PPTP UNI, 根据该 ONU PPTP UNI确定需要关 联的 ONU PPTP UNI业务模板， 使用该 ONU PPTP UNI业务模板作用于该 ONU PPTP UNI。
不同类型的业务流对应不同类型的 ONU PPTP UNI, 例如， 上网业务 使用 Ethernet UNI、 VoIP语音业务使用 POTS UNI等，并且一个业务流只关 联一个 ONU PPTP UNI, 因此， UNI配置单元根据业务流的类型便能够选 择出业务流所要关联的 ONU PPTP UNI。
对于不同类型的 ONU PPTP UNI, 进行 PON业务配置时， 需要为其配 置具体的业务属性数据。 例如， 对于 VoIP语音业务， 需要为 POTS UNI配 置语音业务属性数据， 包括 H.248或者 MGCP、 SIP等语音协议参数。 为简 化配置的复杂性， 减少重复的配置工作量， 本发明方案中， UNI 配置单元 使用相应的 ONU PPTP UNI业务模板作用于 ONU PPTP UNI。具体地， UNI 配置单元可以通过 ONU PPTP UNI业务模板的标识或关键信息选择出相应 的 ONU PPTP UNI业务模板。
步骤 206:配置单元中的 QoS配置单元确定承载业务流的 ONU的逻辑 端口及 OLT的上联虚端口。 配置管理员可以根据需要选择已经存在的 ONU 的逻辑端口或创建新 的 ONU的逻辑端口， 并根据业务流需要关联的 ONU端和 OLT端， 选择已 经存在的 OLT的上联虚端口或创建新的 OLT的上联虚端口。 如果 ONU的 逻辑端口与 OLT的上联虚端口是 1:1的关系， 则选择或创建 OLT的上联虚 端口的步骤可省略。
由于 ONU的逻辑端口和 OLT的上联虚端口的确定并没有一定的前后 执行顺序， 因此， 配置管理员也可以根据需要选择已经存在的 OLT的上联 虚端口或创建新的 OLT的上联虚端口， 并根据业务流需要关联的 ONU端 和 OLT端，选择已经存在的 ONU的逻辑端口或创建新的 ONU的逻辑端口。 如果 OLT的上联虚端口与 ONU的逻辑端口是 1:1的关系， 则选择或创建 ONU的逻辑端口的步骤可省略。
步骤 207~步骤 208:为保证业务流的功能全面性，需要对 OLT端和 ONU 端分别配置 QoS参数， QoS配置单元根据业务流的业务信息确定需要关联 的 QoS模板，使用该 QoS模板分别作用于 ONU的逻辑端口及 OLT的上联 虚端口。
QoS配置单元可以通过 QoS模板的标识或关键信息选择出相应的 QoS 模板。
如果步骤 206中是选择已经存在的 ONU的逻辑端口和 /或 OLT的上联 虚端口， 当已经作用于所选择的 ONU的逻辑端口和 /或 OLT的上联虚端口 的 QoS模板与所需的 QoS模板相符， 则可以不进行相关操作。
步骤 209~步骤 210: 为保证业务流的灵活性， 需要对 OLT端和 ONU 端分别配置业务划分与转发的相关业务属性数据， 划分与转发配置单元根 据业务流的业务信息及承载业务的 PON系统的网络环境确定业务划分与转 发， 并对 OLT端和 ONU端分别进行配置。
如果全局配置模板不包括业务划分与转发系列模板， 则划分与转发配 置单元根据业务流的业务信息及承载业务的 PON系统的网络环境确定业务 划分与转发后， 直接在 OLT端和 ONU端分别配置业务划分与转发的相关 业务属性数据。
如果全局配置模板包括业务划分与转发系列模板， 则划分与转发配置 单元根据业务流的业务信息及承载业务的 PON系统的网络环境确定业务划 分与转发后， 使用相应的业务划分与转发模板分别作用于 OLT端和 ONU 端。 划分与转发配置单元可以通过业务划分与转发模板的标识或关键信息 选择出相应的业务划分与转发模板。 如果全局配置模板中没有适用的业务 划分与转发系列模板， 则直接在 OLT端和 ONU端分别配置业务划分与转 发的相关业务属性数据； 进一步地， 根据当前需要进行的 PON业务配置进 行设置， 相应地添加至业务划分与转发系列模板中。
业务划分与转发的相关业务属性数据或业务划分与转发模板中包含的 信息如 VLAN、 VLAN转换、 SVLAN、 优先级处理方式、 优先级、 以太网 类型、 TPID等。
根据以上描述可见， 虽然具体釆用的 PON技术可能有所不同， 但无论 基于何种 PON技术， 基于业务流的业务属性数据都是具有一定的共性的， 使具有共性、 通用性的业务属性数据形成模板， 便能够为 PON业务配置带 来大大的简化， 不再会因 EPON技术和 GPON技术的不同， 而存在 PON业 务配置的较大差异。
以上 PON业务配置的过程中， 如果不存在适用的相关模板， 可以先根 据业务流的业务信息设置相应模板， 然后再使用相应模板进行配置。 设置 好的模板添加至相应的系列模板中， 在后续情况相同的配置中可以再次使 用， 避免了重复配置。
以上 PON业务配置的过程中， 各部分的配置并没有明显的先后执行顺 序， 可以同时进行， 也可以任意地先后执行。 图 3为本发明中实现 PON业务配置的装置结构示意图， 如图 3所示， 该装置包括： 模板存储单元和配置单元， 其中， 模板存储单元用于存储设 置的全局配置模板； 配置单元用于进行 PON业务配置时， 根据业务流的业 务信息使用设置的全局配置模板作用于业务配置点。
模板存储单元中存储的全局配置模板至少包括 ONU PPTP UNI系列业 务模板和 QoS系列模板； 所述业务配置点包括 ONU PPTP UNI、 ONU的逻 辑端口和光线路终端 OLT的上联虚端口； 相应地， 配置单元包括： UNI配 置单元和 QoS配置单元， UNI配置单元用于根据业务流的类型使用对应的 ONU PPTP UNI业务模板作用于 ONU PPTP UNI; QoS配置单元用于根据 业务流的业务信息使用对应的 QoS模板作用于 ONU的逻辑端口和 OLT的 上联虚端口。
所述配置单元进一步包括： 划分与转发配置单元。 模板存储单元中存 储的全局配置模板进一步包括业务划分与转发系列模板时， 划分与转发配 置单元相应地用于才艮据业务流的业务信息及^ ^载业务的 PON系统的网络环 境， 使用对应的业务划分与转发模板作用于业务流关联的 OLT端和 ONU 端； 才艮据业务流的业务信息及 ^^载业务的 PON系统的网络环境确定业务划 分与转发后， 如果全局配置模板中没有适用的业务划分与转发系列模板， 则直接在 OLT端和 ONU端分别配置业务划分与转发的相关业务属性数据， 进一步地， 根据当前需要进行的 PON业务配置进行设置， 相应地添加至业 务划分与转发系列模板中。 模板存储单元中存储的全局配置模板不包括业 务划分与转发系列模板时， 划分与转发配置单元相应地用于根据业务流的 业务信息及承载业务的 PON系统的网络环境确定业务划分与转发后， 直接 在 OLT端和 ONU端分别配置业务划分与转发的相关业务属性数据。
所述装置还包括模板设置单元， 用于根据可能存在的各种业务流设置 全局配置模板， 并将设置好的全局配置模板存储于模板存储单元。 所述配置单元进一步用于需要创建端到端的业务流时， 为业务流设置 名称来标 i只该业务;克。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围， 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进 等， 均应包含在本发明的保护范围之内。
