Description

无源光网络系统中建立管理维护通道的方法、 装置及系统 本申请要求了 2008年 5月 28日提交的、 申请号为 200810113234. 1、 发明名称为 "无源光网络 系统中建立管理维护通道的方法、 装置及系统" 的中国申请的优先权, 其全部内容通过引用结合在 本申请中。 技术领域
本发明涉及一种通信技术, 尤其涉及一种无源光网络系统中实现自动建立网管与用户侧设备之 间的管理维护通道的方法、 装置及系统。
发明背景
无源光网络(P0N, Passive Optical Network)是一种采用点到多点(P2MP, Point to Multi-Point ) 结构的单纤双向光接入网络, 其典型拓扑结构为树型, 如图 1所示, 其中无源光分路器可以是一级 分光或者多级分光。
随着 P0N技术的发展, 光纤到户 /光纤到大楼 (FTTH/FTTB, Fiber To The Home/Fiber To The Building) 的应用模式日趋成熟。 比如, 在图 2所示的以太无源光网络 (EP0N, Ethernet Passive Optical Network) 中, 对于 FTTH应用模式, 终端通常采用光网络终端 (0NT, Optical Network Terminal ) , 对于 FTTB应用模式, 终端通常采用光网络单元 (0NU, Optical Network Unit ), 多住 户单元(MDU, Multi-Dwelling Unit )是 0NU的一种, 多用于多用户住宅区域。对于 FTTB应用模式, 电信运营商会大量部署 MDU这种类型的小规格设备,并且对小规格设备的调测提出了免软调的需求, 上述免软调可以极大地降低运营商的安装和维护费用。 上述的场景不限于 EP0N, 还可以为吉比特无 源光网络 (GP0N, Gigabit Passive Optical Network) 0
因此, 针对上述的场景, 要求小规格设备在硬件安装完毕后, 能够自动打通同上级光线路终端 (0LT, Optical Line Termination) 设备之间的维护通道, 用户能够直接在远端网管设备上对该小 规格设备进行管理。
现有的一种技术方案是运营商在安装完 MDU设备之后, 客服人员进行 MDU设备安装时, 提前准 备好配置每个 MDU设备的配置脚本, 在 MDU设备完成硬件联调之后, 通过串口或者 Telnet (请提供 中文)登陆到 MDU设备上,执行配置脚本,完成 MDU设备的初始管理虚拟局域网(VLM, Virtual Local Area Network),管理 IP、静态路由、简单网络管理协议(SNMP, Simple Network Management Protocol ) 管理参数的配置。
现在为缩短用户配置的难度, 常使用外部工具 (如个人数字助理、 笔记本电脑等) 进行自动化 配置, 即将开发的自动配置数据的工具安装到个人数字助理或笔记本电脑上, 再连接到 MDU设备后, 自动完成 MDU设备的各种数据的配置, 达到简化人工配置工作的目的, 使配置效率有了一定的提高, 但仍需工作人员要在设备安装后到 MDU设备所在现场进行配置。
从上述现有技术中对 MDU等小规格设备的配置处理过程中, 发明人发现上述现有技术至少存在 以下问题: 随着光网络应用的普及, 部署的 MDU设备等这种小规格设备数量特别大, 并且设备的安装场所 一般离运营商的中心机房比较远。 开局过程一般是硬件人员或者安装人员将设备在小区、 楼道等地 方安装好, 然后由软调人员再到现场区配置设备的网管通道, 以便开局的后续步骤和日常维护中能 远程管理这些设备。 另一方面, 现场配置的数据也要根据不同局点的要求配置不同的地址, 需要提 前制作设备配置脚本, 准备工作繁杂, 容易出错, 对于数量特别大的 MDU设备等小规格设备来讲, 该方式的人力成本较高。
发明内容

由上述本发明实施方式提供的技术方案可以看出, 本发明实施方式通过使光线路终端与用户侧 设备之间通过不同的二层协议 (如 0AM、 0MCI、 BPDU等二层协议) 完成用户侧设备的管理维护通道 的自动配置打通。 由于采用不同二层协议打通管理维护通道可以很好应用于不同的设备的接口, 更 具灵活性、 且应用更方便。 解决了现有的某些二层协议没有支持扩展协议, 不能打通维护通道的缺 点, 该方法还具有: ①降低设备安装软调成本, 自动打通用户侧设备的维护通道, 降低了新设备安 装的复杂度, 提高的客户满意度; ②无需现场配置数据, 减少了配置数据出错的几率, 同时提高设 备安装的速度; ③更换设备简单, 无需现场重新配置数据, 降低维护成本。 附图简要说明

实施本发明的方式
本发明实施方式提供一种无源光网络系统中自动建立管理维护通道的方法、 装置及系统, 其实 质是局端的 0LT设备接收网管设备下发的配置信息,打通与所连接的网管设备之间的管理维护通道。 0LT设备通过与安装后的用户侧的小规格的用户侧设备采用二层协议 (根据应用不同的网络使用不 同的二层协议) 进行交互, 并将在局端的网管设备上配置的用于用户侧设备使用的管理配置信息下 发给用户侧设备,用户侧设备则根据收到的所述管理配置信息,打通用户侧设备的管理维护通道(用 户侧设备与 0LT设备之间的维护通道), 并使 S丽 P管理协议生效, 通过打通的局端侧的管理维护通 道(0LT设备与网管设备之间的维护通道)和打通的用户侧的管理维护通道(0LT设备与用户侧设备 之间的维护通道) 形成局端的网管设备直接对用户侧设备的网管维护通道。
上述小规格用户侧设备一般是指光纤到大楼 FTTB形式中使用的光网络单元 0NU设备, 如: 可以 是单住户单元 SFU型 0NU设备、 家庭网关单元 HGU型 0NU设备、 单商户单元 SBU型 0NU设备、 多商 户单元 MTU型 ONU设备等中的至少一种。
为便于对本发明实施例的理解, 下面将结合附图以几个具体实施例为例做进一步的解释说明, 且各个实施例并不构成对本发明实施例的限定。 实施例一
该实施例提供的自动建立管理维护通道的方法的处理流程见图 3所示, 包括如下处理步骤: 步骤 31、 在局端的网管设备上增加用户侧设备, 即局端的网管设备为 0LT、 用户侧设备指定配 置 息。
步骤 32、 0LT接收上述网管设备下发的配置信息, 并根据该配置信息中的第一配置信息创建与 网管设备之间的管理维护通道。
步骤 33、 在用户侧设备安装并上电启动后, 0LT将所述配置信息中的第二配置信息发送给用户 侧设备, 用于用户侧设备根据该第二配置信息建立用户侧的管理维护通道。
步骤 34、 网管设备与 0LT、 0LT与用户侧设备之间的管理维护通道连接通信, 形成网管设备与 用户侧设备之间网管维护通道。
以 MDU设备作为用户侧设备的例子来说明, 上述处理流程在实际中完成了 MDU设备的即插即用
(Plug&Play), 使局端 0LT与 MDU设备之间自动完成以下配置工作:
配置底层通道 (主要是管理 VLAN)、 启动 3层接口;
配置 MDU设备本机的管理 IP (管理 VLAN的 3层接口 IP);
配置静态路由, 用于与 server的流量转发, 主要是缺省网关;
配置简单网络管理协议 SNMP参数, 如 snmp团体名、 snmp trap服务器 IP地址等; 通过上述配置后, 即可完成局端网管与 MDU设备之间的网管维护通道的打通, 局端网管可以通 过打通的网管维护通道对 MDU设备进行后续的配置和管理。
该实施例实现了在用户侧设备安装并上电启动后, 局端的 0LT设备与用户侧设备之间进行交互 自动完成, 省去了以往需工作人员到现场对用户侧设备的配置、 调试过程, 大大节省了人力。
实施例二
该实施例提供了在图 4所示的用户侧设备 MDU与局端 0LT的组网中, 实现自动建立网管与用户 侧设备之间的管理维护通道的方法, 从而自动打通用户侧设备的管理维护通道, 通过局端的网管设 备对用户侧设备进行配置、 调测, 实现其免软调, 该方法的处理流程如图 5所示, 具体包括: 步骤 51, 在局端的网管设备上增加用户侧设备, 即局端的网管设备为 0LT设备和用户侧设备指 定配置信息, 并预留维护通道资源; 其中, 配置信息中包括用于 0LT设备的第一配置信息和用于用 户侧设备 (MDU设备) 的第二配置信息;
步骤 52, 局端的 0LT设备接收网管设备下发的配置信息, 0LT设备根据配置信息中的第一配置 信息创建 0LT设备与网管设备之间的业务连接通道作为局端侧的管理维护通道;
步骤 53, 0LT设备与用户侧设备之间通过对应的二层协议进行交互, 完成对该用户侧设备的测 距、 注册和认证后, 将所述配置信息中用于用户侧设备的第二配置信息下发至用户侧设备, 用户侧 设备根据所述的第二配置信息建立用户侧的管理维护通道;
本领域技术人员应该能理解, 0LT设备与用户侧设备之间也可以通过其他传输协议将第二配置 信息下发至用户侧设备。
步骤 54, 打通的局端侧的管理维护通道与用户侧的管理维护通道形成局端的网管设备管理用户 侧设备的网管维护通道。
当网管维护通道打通后, 局端通过该网管维护通道, 可以完成对用户侧设备的后续配置处理, 如语音 VOIP三层接口及各种配置服务器的配置等。
下面对上述方法中所涉及的各步骤进行具体说明:
其中,步骤 51中,增加用户侧设备是在局端的网管设备为 0LT设备和用户侧设备指定配置信息, 并预留维护通道资源, 主要是指在局端网管设备的处理系统中增加一个 0NU设备, 局端网管设备的 处理系统中生成对应该用户侧设备的管理对象, 并对这个对象生成相应的数据, 如 0NU 编号、 0NU 的密码认证方式、 描述信息等; 配置用户侧设备使用的第二配置信息具体包括: 用户侧设备使用的 IP地址, 虚拟局域网 VLAN及默认网关, VLAN及默认网关可以与局端的 VLAN及默认网关重用, 即与 光线路终端的 VLM及使用的网关重用。
对 IP地址的分配: 局端的网管设备可以根据用户侧设备的标识信息 (如: 无源光网络 P0N MAC 地址和 /或该用户侧设备的序列号 SN等信息),从 IP地址池中为不同的用户侧设备分配的不同 IP地 址, 或者也可以由用户为每个用户侧设备单独指定不同的 IP地址。
步骤 52中, 局端 0LT设备与用户侧设备之间使用不同类型的网络连接时, 则使用不同的二层协 议, 如局端 0LT设备与用户侧设备之间为无源光网络 P0N, 若 PON使用以太无源光网络 ΕΡΟΝ, 则对 应的二层协议采用操作、 管理和维护 0AM协议; 如局端 0LT设备与用户侧设备之间为吉比特无源光 网络 GP0N, 则对应的二层协议采用 0NU管理控制接口 0MCI协议, 可以理解, 根据使用不同的无源 光网络, 则应选择与该网络对应的二层协议, 不因某一具体的二层协议造成任何限制。
该实施例提供的一个具体的应用场景为: 0LT设备在局端, MDU设备在用户侧,一般在居民区的 楼道内, 局端的 0LT设备的 P0N通过分光器到用户侧的 MDU, 完成 0LT同 MDU之间的物理通道的连 接。 该实施例提供的在上述具体的应用场景下, 用户侧设备的管理维护通道的打通过程的处理流程 如图 6所示, 具体包括如下步骤:
下面描述在这种场景下初始物理通道的打通过程。
步骤 61、 在 0LT侧, 用户在对应的 P0N侧增加 MDU设备;
步骤 62、 在 0LT侧, 用户通过与该 0LT设备连接的网管设备配置与该 0LT设备连接的 MDU设备 的管理用 IP地址、 管理用 VLAN和默认网关, 其中, MDU设备的管理用 VLAN、 默认网关可以同 0LT 的管理 VLAN、 默认网关重用;
步骤 63、 MDU设备上电启动后, 与 0LT通过 P0N协议交互 (EP0N是通过 MPCP协议, GP0N是通 过 PL0AM协议), 完成 MDU设备的测距、 注册、 认证;
步骤 64、 0LT收到注册报文后, 由该 0LT设备连接的网管设备自动分配管理 IP地址给 MDU设备 (由于 0LT和 MDU设备之间是 P2MP共享链路, 因此可以采用 MDU设备的标识 (如 MDU PON MAC, SN 等) 信息来为不同的 MDU设备分配不同的 IP地址);
0LT自动在连接网管设备的 EP0N口上创建与所连接的网管设备之间的业务连接通道作为局端侧 的网管维护通道 (局端侧的网管维护通道可以在 0LT设备接收到网管设备下发的配置信息后, 根据 配置信息中针对 0LT设备的第一配置信息建立), 将 0LT侧的管理维护通道打通, 0LT与网管设备之 间的网管维护通道的打通不受 0LT与 MDU之间网管维护通道是否打通或什么时机打通的影响, 实际 中根据具体配置的不同, 也可以选择在其它时机打通 0LT与网管设备之间的网管维护通道;
步骤 65、 0LT通过 P0N管理协议 (EP0N是通过 0AM协议, GP0N是通过 0MCI协议, 若为其他无 源光网络, 还可以采用对应的二层协议), 将 MDU设备的管理 IP地址、 管理 VLAN、 默认网关信息下 发给 MDU设备;
步骤 66、 MDU设备解析 P0N管理协议报文中管理 IP/VLAN/默认网关信息后, 根据管理 IP/默认 网关信息创建三层接口, 并将三层接口绑定到管理 VLAN上, 打通 MDU设备的维护通道, 同时将 SNMP 相关参数配置生效, 与局端打通的管理维护通道形成打通的局端至 MDU设备的网管维护通道, 即局 端 0LT设备自动打通接入用户侧 MDU设备的下行口和该 0LT设备连接网管设备的上行口之间的维护 通道;
步骤 67、 通过已打通网管维护通道, 局端的网管设备可以直接配置 MDU设备的后续配置信息, 如语音 VOIP三层接口、 各种配置服务器 (如 NTP/SYSLOG server地址等等)。
实施例中以 MDU设备作为用户侧设备为例进行说明, 但不以 MDU设备对用户侧设备构成任何限 制,在实际中应用在用户侧的其它类型的用户侧设备均可以采用上述方法进行网管维护通道的打通。 所述的用户侧设备可以为: 单住户单元 SFU型 0NU、 家庭网关单元 HGU型 0NU、 单商户单元 SBU型 0 、 多商户单元 MTU型 0NU等设备中的至少一种。
实施例三
实际中还存在用户侧设备为多个, 且多个用户侧设备采用多级级联状态使用的应用场景, 该实 施例提供的多级级联的用户侧设备与局端 0LT的组网示意图如图 7所示, 本实施例对这种多级联的 用户侧设备的管理维护通道打通过程进行说明, 具体打通步骤见图 8:
步骤 81, 局端的网管设备指定配置信息 (包括用于光线路终端的 0LT设备的第一配置信息和用 于用户侧设备的第二配置信息, 并预留维护通道资源;
步骤 82, 局端的 0LT设备与所述用户侧设备之间通过对应的二层协议进行交互, 具体是由用户 侧的最后一级设备经过中间级设备向第一级设备 (直接与局端 0LT设备连接的用户侧设备) 发送桥 协议数据单元 BPDU报文; 第一级设备将收到的带有各级设备的物理位置信息的 BPDU报文封装在与 局端交互对应使用的二层协议报文中发送至局端 0LT设备, 完成对用户侧设备的测距、注册和认证; 局端 0LT设备接收网管设备下发的配置信息, 根据配置信息中的第一配置信息, 0LT设备与网 管设备之间创建业务连接通道作为局端侧的管理维护通道;
步骤 83, 所述局端的 0LT设备将所述配置信息中用于用户侧设备的第二配置信息发送至用户侧 设备, 用户侧设备根据局端下发的所述第二配置信息打通用户侧的管理维护通道; 具体是由用户侧 的第一级设备将收到的局端 0LT设备下发的封装所述管理配置信息的二层协议报文转换为 BPDU报 文, 所述转换得到的 BPDU报文经各中间级设备发送至最后一级设备, 逐级打通用户侧设备的管理维 护通道, 所述的逐级打通是第一级打通之后, 才可以打通第二级, 以次类推, 直至打通最后一级的 用户侧设备;
步骤 84, 打通的所述局端侧管理维护通道与所述用户侧的管理维护通道形成局端的网管设备直 接管理用户侧设备的网管维护通道。
下面以实际中对多级级联的 MDU设备的管理维护通道的自动打通过程, 对本实施例的方法作进 一步说明:
本实施例主要是考虑多级级联场景下, 第一级 MDU设备之下级联的 MDU设备维护通道自动打通 的方法, 关键是进行 BPDU报文和 0AM报文之间的转换, 而 0LT与网管设备之间网管维护通道的打通 与实施例一相同:
① MDU2设备在初始上电完毕后, 会向上级的 MDU设备的两个 GE口发送 BPDU报文;
②设备在收到 MDU2设备的 BPDU报文后, 捕获到该设备的 CPU上, 在 BPDU报文中附加级联的物 理位置信息 (即该 MDU1设备的物理位置信息), 然后将 BPDU报文向上行口发送;
③ MDU1设备在收到 MDU2设备的 BPDU报文后, 将该 BPDU报文捕获到 MDU1设备的 CPU上, 并在 该 BPDU报文中附加自身的物理位置信息, 然后将 BPDU报文向上行口发送;
④ MDU0设备在收到 MDU1设备的 BPDU报文后, 将该 BPDU报文捕获到 MDU0设备的 CPU上, 并在 该 BPDU报文中附加自身的物理位置信息, 将 BPDU的净荷 T0P0描述信息提取出来, 封装在与局端 0LT通信的 P0N管理协议报文中 (若与局端间为 EP0N网络, 则采用 0AM协议, 若与局端间为 GP0N 网络, 则采用 0MCI协议), 经 P0N上行口发送到 0LT侧;
⑤ 0LT收到注册报文后, 由与该 0LT设备连接的网管设备中自动从管理 MDU设备使用的管理 IP 地址池(专用于为管理的 MDU设备分配 IP地址的 IP地址池) 中, 为各 MDU设备自动分配管理 IP地 址, 并通过所连接的 0LT设备将该 IP地址、 管理用 VLAN、 0NU的默认网关信息打包到 P0N管理协议 报文中, 发给 MDU0设备;
©MDU0设备将 P0N管理协议报文转换为 BPDU报文, 将 BPDU报文发送 MDU1设备, MDU1设备将 BPDU报文转发到 MDU2设备; 其中 P0N管理协议报文转换为 BPDU报文的转换处理主要是先去掉报文 中的二层协议报文头 (即 P0N管理协议报文头, 若为 EP0N管理协议报文或 GP0N管理协议报文, 则 为 0AM或 0MCI报文头), 然后在静荷报文前面加上 BPDU的报文头, 并且填充必要的 BPDU头信息, 转换后, BPDU报文中包含对各级 MDU设备的配置管理信息;
©MDU2设备解析到 BPDU报文中的管理配置信息中的管理 IP/VLAN/默认网管信息后, 根据管理 IP/默认网管信息创建三层接口, 并将三层接口绑定到管理 VLAN上, 在 MDU0设备、 MDU1设备维护 通道打通的基础上, 打通 MDU2设备的维护通道, 同时将 S丽 P相关参数配置生效, 使局端侧打通的 维护通道与用户侧设备打通的维护通道形成局端网管设备管理用户侧设备的网管维护通道;
⑧通过所述的网管维护通道, 网管可以配置 MDU2设备的后续配置信息, 如语音 VOIP三层接口、 各种配置服务器 (如 NTP/SYSLOG server地址等)。
在本发明实施例的打通方法中, 对于非 XP0N的管理方式, 可以通过其他的二层协议报文或者三 层协议报文承载 MDU的初始维护通道配置信息, 来完成 MDU初始维护通道的打通。

所述建立的网管设备 121与光线路终端 122之间的局端侧的管理维护通道与所述建立的光线路 终端 122与用户侧设备 123之间的用户侧的管理维护通道连接通信形成网管设备 121直接管理所述 用户侧设备 123的网管维护通道。
