Description

配置以太无源光网络系统的光网络单元的方法及相关设备 技术领域
本发明涉及光网络单元的配置技术, 尤其涉及一种配置以太无源光网 络系统的光网络单元的方法及相关设备。 背景技术
在通信网络中, 无论是核心网、 传输网还是接入网, 其发展的首要动 力是业务, 是终端用户的需求。 从业务发展现状来看, 高带宽业务逐步涌 现, 网络带宽提速已经成为迫切需求, 而无源光网络(Powerless Optical Network, PON ) 以其容量大、 传输距离长、 较低成本、 全业务支持等优势 成为宽带接入的热点。 PON在提供业务组合的同时, 实现了高可靠性和高 性能, 已经成为了下一代光接入网的主要发展方向。 以太无源光网络
( Ethernet Powerless Optical Network, EPON )由于基于以太网的成熟技术, 得到了广泛的应用。
如图 1 所示, EPON 中最主要的三部分包括位于局端的光线路终端
( Optical Line Terminal, OLT ), 位于终端的光网络单元( Optical Network Unit, ONU ), 以及光配线网 (Optical Distribution Network, ODN )。 PON
"无源 " 是指 ODN全部由光分路器( Splitter )等无源器件组成, 不包含有 任何有源电子器件或电源。 通常 OLT上与 ODN相联的端口为 OLT的下联 口,也称为 OLT的 PON口; ONU上与 ODN相联的端口为 ONU的上联口, 也称为 ONU的 PON口。
在 EPON中 , OLT和 ONU之间的配置管理信息是通过一种被称为 OAM
( Operation、 Application and Management )的数据帧进行传递的。 一般的配 置方法是 OLT发出单播形式的 OAM配置帧 , ONU接收到发给自身的 OAM 后, 根据 OAM中包含的配置信息对自身进行配置。 该 OAM帧的前导码构 成方式如图 2所示, 包括模式( mode ) 字段 lbit和逻辑链路标识( Logical Layer Identification, LLID )字段 15bit。 当配置前导码中的模式字段为 0时, 配置数据以单播形式发送, LLID字段写明单播对象; 当模式字段为 1时, 配置数据以广播形式发送, 并且其 LLID字段为全 "1" 时的广播消息, 被 所有 ONU接收。 只有所有 ONU的配置情况完全相同时才会出现 OAM中 的模式和 LLID字段均全为 1的情况。现有的 EPON系统的配置一般是通过 单播形式,下发给某一个 ONU。如果要对 OLT的同一个 P0N口的多个 0NU 配置相同的配置数据(不是所有的 0NU ), 则需要多次以单播形式将相同 的配置数据, 分别下发给不同的 0NU。 当需要配置的 ONU数量较大时, 这种配置方法的效率很低, 而且 PON系统的下行带宽利用率也较低。 发明内容
本发明提供一种配置 EP0N系统的 0NU的方法及相关设备,用以解决 现有技术中 EP0N通过 0AM大批量配置 0NU时效率不高的问题。
本发明提供了一种配置 EP0N系统的 0NU的方法, 包括: 0NU接收 0LT广播的配置数据帧,所述配置数据帧包含根据 0NU需要使用的配置数 据产生的配置模板和模板标识;所述 0NU判断出所述配置数据帧携带的模 板标识与自身存储的模板标识相同时, 提取所述配置数据帧携带的配置模 板; 以及所述 0NU应用提取的所述配置模板对自身进行配置。
本发明还提供了一种光网络单元, 包括: 数据帧接收单元, 用于接收 0LT广播的配置数据帧,所述配置数据帧包含根据 0NU需要使用的配置数 据产生的配置模板和模板标识; 判断单元, 用于判断所述数据帧接收单元 接收的所述配置数据帧携带的模板标识与所述 0NU存储的模板标识是否 相同; 模板提取单元, 用于在所述判断单元的判断结果为是时, 提取所述 OAM帧携带的配置模板; 配置单元, 用于应用所述模板提取单元提取的配 置模板对自身进行配置。
本发明还提供了一种光线路终端, 包括: 配置模板生成单元, 用于根 据 ONU 需要使用的配置数据产生配置模板及模板标识; 对应关系存储单 元, 用于存储光网络单元与配置模板的模板标识的对应关系; 模板标识下 发单元, 用于向光网络单元下发对应的模板标识; 数据帧生成单元, 生成 包含配置模板及相应的模板标识的数据帧,并通过广播方式下发到各 ONU。
本发明提供一种配置 EPON 系统的 ONU的方法及相关设备。 通过对 OLT的同一个 PON口下的多个 ONU的常用配置数据生成配置数据模板, 为生成的每个配置模板分配一个唯一的模板标识 (预留的 LLID号)。 将配 置模板连同模板标识以广播的形式下发到 OLT的同一个 PON 口下所有的 ONU, 使得该 PON系统中, 需要进行同样配置的多个 ONU的配置数据一 次完成下发, 实现了简洁、 高效的配置, 提高了 PON系统中中通过 OAM 配置 ONU的效率。 附图说明

本发明实施例 1提供一种配置 EPON系统的 ONU的方法,其流程图如 图 3所示, 包括步骤:
S101、 ONU接收 OLT广播的 OAM帧;
所述 OAM帧包含根据 ONU需要使用的配置数据产生的配置模板和模 板标识。
5102、 ONU判断出所述配置数据帧中携带的模板标识与自身存储的模 板标识相同时, 提取所述配置数据帧携带的配置模板;
5103、 ONU用所述配置模板对自身进行配置。
为了实现 OAM配置数据的一次下发并批量配置到多个 ONU的目的, 需要两个步骤: 配置模板分类和下发, 以及配置模板接收和 ONU的配置。 下面将通过实施例进行详细的说明。
本发明实施例 2提供了一种配置模板分类和下发的方法流程, 如图 4 所示, 包括步骤:
5201、 在 OLT上, 将 ONU常用的配置数据作为模板, 保存下来, 得 到多个配置模板; 并对不同的配置模板进行编号处理, 编号可以为 MB1、 MB2 MBn等, 但不局限于此种编号方式。
5202、 OLT 内部为每个配置数据模板分别分配不同的模板标识, 模板 标识是系统预留的多个互不相同的逻辑链路标识 LLID。
以上两步骤完成了配置模板的产生过程, 之后需要将各个配置模板的 模板标识下发给相关的 ONU, 以便在之后的步骤中各个 ONU能够依据模 板标识获取广播的配置数据帧中与自身相应的配置模板。
5203、 在 OLT上将配置模板的模板标识和需要依照该模板进行配置的 ONU进行绑定, 形成一个绑定关系表, 表的内容为: MBn, ONU标识, 模 板标识; S204、 OLT将 ONU标识,模板标识的绑定关系下发到每一个 ONU上, 使 ONU确定自身需要选择接受的 OAM配置模板的模板标识。 ONU可以 将这个绑定关系存储在自身的调和( RS , Reconciliation Sublayer )子层, 存 储的信息形式可以为: MBn, 模板标识。
OLT可以以单播的形式下发绑定关系到 ONU上。这种情况下可以每次 仅下发绑定关系表中的一个绑定关系, ONU接收到绑定关系后, 提取自身 相关的模板标识直接将其存储在自身的 RS子层; 也可以向多个 ONU分别 下发整个绑定关系表, 然后 ONU确定自身相关的绑定关系并提取出来, 存 储在自身的 RS子层。
OLT也可以通过广播的形式直接将 S203中形成的绑定关系表一次性下 发到每个 ONU, 各个 ONU接收到绑定关系表以后, 提取其中自身相关的 绑定关系并将这个绑定关系存储在自身的 RS 子层, 存储的信息形式为: MBn, 模板标识;
以上四个步骤完成了配置模板的分类和下发,使得各个 ONU都确定了 自身可以接收的配置模板的模板标识。
本发明实施例 3提供了一种配置模板接收和光网络单元的配置的方法 流程, 如图 5所示, 包括步骤:
5301、 在 OLT上, 将配置模板绑定到具体的 ONU的时候(批量下发 配置数据时), 将前导码中的模式字段设置为 1 , 并逻辑链路标识字段设置 为当前待下发的配置模板的模板标识。 釆用广播的方式, 将包含此前导码 的配置模板下发到同一个 PON口下所有的 ONU;
5302、 ONU接收到前导码带有广播模式标识的配置数据帧时, 根据存 储的模板标识对下发的配置数据帧的前导码中的 LLID字段进行匹配;如果 匹配成功, 转到 S303; 如果匹配不成功, 将该广播的配置数据帧丟弃;
5303、 对接收到的配置数据帧进行去除前导码的操作, 利用剩下的配 置模板的内容, 对 ONU自身进行相应的配置处理。
在配置 ONU之前, 还包括对去除了前导码的配置模板进行校验处理, 典型的可以釆用 CRC校验方式。
对于一个 ONU 实际上是兼容了原有的单播和广播的配置下发方式进 行自身配置, 并且能够接收以类似于组播的形式批量下发的 OAM 配置数 据。
本发明实施例 4给出了对于一个具体的 ONU接收 OAM帧的处理流程, 如图 6所示, 包括步骤:
S401、 ONU对接收到的数据帧中的配置数据帧的前导码中的模式字段 进行判断, 判断出模式字段为 0, 则为单播, 转到 S402; 否则转到 S403 ;
5402、 判断前导码中的 LLID是否是本 ONU的 LLID , 如果判断结果 为否, 转到 S406; 如果前导码中的 LLID是本 ONU的 LLID, 则转到 S405 步骤;
5403、 判断前导码中的 LLID是否是广播地址(即字段是否全为 1 ), 如果判断结果为否, 则转到 S404步骤; 如果判断结果为是, 则转到 S405;
5404、判断前导码中的 LLID是否是自身可以接收的配置模板标识,如 果判断结果为是, 则转到步骤 S405; 否则, 丟弃该数据帧, 转到 S406;
5405、 对接受到的数据帧去除接收到的帧的前导码, 完成 CRC校验, 进入后续正常的配置处理流程;
S406、 丟弃该数据帧。
通过这种处理方法, 可以有效利用 EPON系统的点到多点的广播的特 征, 批量下发 OAM配置数据, 提高了下行带宽的利用率以及配置 ONU的 效率。
本发明实施例 5对应的提供了一种光网络单元, 结构如图 7所示, 包 括: 数据帧接收单元 71 , 用于接收 OLT广播的配置数据帧, 所述配置数据 帧包含根据 ONU需要使用的配置数据产生的配置模板和模板标识;
判断单元 72,用于判断所述数据帧接收单元 71接收的所述配置数据帧 携带的模板标识与所述 ONU存储的模板标识是否相同;
模板提取单元 73 , 用于在所述判断单元 72的判断结果为是时,提取所 述配置数据帧携带的配置模板;
配置单元 74,用于应用所述模板提取单元 73提取的配置模板对自身进 行配置。
较佳的, 结构如图 7a所示, 还可以包括:
模板标识接收单元 7011 , 用于接收 OLT发送的模板标识, 所述模板标 识是 OLT根据所述 ONU使用的配置数据生成的配置模板的标识, 所述模 板标识由 OLT发送到所述 ONU;
模板标识存储单元 7012, 用于将所述模板标识接收单元 701接收的模 板标识存储。
较佳的, 结构如图 7b所示, 也可以包括:
