本发明通过定义一种简单有效的管理实体( Managed Entity, ME ) 的功 能扩展来实现光网络单元组播预览功能,故能够规范 GPON系统的互通测试, 提高互通测试的效率,从而对于 GPON系统中的 OLT及 ONU产品的技术发 展具有极大的推动作用。
附图概述 图 1为本发明的实现组播预览功能的方法实施例的流程图; 图 2 为本发明实现组播预览功能的光网络单元装置实施例的结构框图。
本发明的较佳实施方式 以下结合附图和优选实施例对本发明的技术方案进行详细地阐述。 以下 例举的实施例仅仅用于说明和解释本发明, 而不构成对本发明技术方案的限 制。 本发明的实现组播预览功能的方法的前提条件,是要对 G984.4标准中对 于 9.3.27 组播操作实体( Multicast operations profile ) 所描述的管理实体 ( ME )进行扩展定义, 该 ME现有的定义如表 1所示。 表 1
Figure imgf000008_0001
从表 1可看出, Dynamic access control list table中规定端口可供观看的组 播频道列表(也可称为项) , 以及组播数据流的 VLAN ID、 GEM port-ID和 输入组带宽( Imputed group bandwidth )等相关信息, 也即此项列表是用于实 现 ONU中组播协议模块白名单访问控制模式的, 即允许观看的组播频道列 表。 白名单访问功能与组播预览功能的前提是一致的,都是允许观看的频道, 其区别仅在于观看时限上。 白名单访问列表中的组播频道是无观看时限限制 的, 其是否可继续观看仅仅取决于组播地址是否会被老化掉。 而组播预览功 能对可观看的时限是有要求的, 一般是 20至 30s左右。 本发明针对上述这种差异性, 结合表 1中现有的 ME定义, 对其中的保 留 (Reserved )字段进行扩展。 该 Reserved字段大小为 2个字节 (16 bits ) 。 本发明使用其中最低位(bit ) , 该最低位的默认值 0 ( 0000 )和标准规定的 一致, 用于标记此项组播频道条目为白名单组播频道条目 (也称项) ; 该最 低位定义为值 1 ( 0001 ) 用于标记此项组播频道条目为预览组播频道条目 (项) 。 要实现本发明需提供 OLT和 ONU对上述 ME扩展定义的支持。 对于 OLT,需要按扩展定义的 ME对 ONU进行配置;对于 ONU,则需要按照 OLT 的配置实现组播预览功能。
图 1 提供了本发明的实现组播预览功能的方法实施例, 涉及一个 OLT 和该 OLT下挂的一个或多个 ONU, 其流程包括: 步骤 1 : OLT完成 ONU注册及其它端口初始化配置; 步骤 2: OLT向相应的 ONU下发创建组播操作实体命令;
OLT 在下发的命令中指明需要 ONU创建的组播操作实体(Multicast operations profile ) 及要西己置々组播频道歹)表 ( Dynamic access control list table ) 。 其中, 对于允许观看的组播白名单的组播频道, 组播频道列表中的 Reserved字段置为白名单组播频道条目的标识值(譬如值为 0 ) ; 对于属于 组播预览的组播频道, 该 Reserved字段置为预览组播频道条目的标识值(譬 如最低 bit置为 1 ) 。 步骤 3: ONU设置 ME, 并存储配置数据;
ONU依据 OMCI协议解析 OLT下发的命令后, 设置对应的 ME, 在验 证命令合法后, 将命令中的配置数据存储到 OMCI全局数据库中。 步骤 4: ONU完成组播白名单条目和组播预览条目的频道配置; 根据存储的配置数据, 同时配置白名单组播频道条目 (项)和预览组播 频道条目 (项) , 根据白名单组播频道条目和预览组播频道条目, 生成相应 的组播地址转发条目 (项) , 并以不同的标记索引加以区分。 步骤 5: ONU向 OLT返回创建组播操作实体响应; 在步骤 2〜5中完成 ONU、 OLT的交互和对接, 便可实现 ONU的组播预 览功能。 步骤 6: OLT将组播数据流下发给相应的 ONU; 步骤 7: ONU按相应的组播地址转发项转发组播数据流; 步骤 8: ONU针对组播白名单频道和组播预览频道对下游设备发送的报 文进行相应的处理。
ONU在处理下游设备 (譬如家庭网关或者机顶盒)发送的 Internet组管 理协议 ( Internet Group Management Protocol, IGMP )力口入 (join )才艮文时: 针对组播白名单频道: 学习组播地址, 在组播地址转发表中配置相应的 组播地址条目 (项) , 按照组播地址老化时间实现老化功能。 对于老化时间 到达前, 根据新收到的组播 join报文自动刷新老化时间。 针对组播预览频道: 学习组播地址, 同时设定一个时长等于预定预览时 间的定时器, 并在组播地址转发表中配置相应的组播地址条目 (项) 。 当定 时器时间到时, 删除相应的预览组播频道条目, 并同时从组播地址转发表中 删除对应的组播地址条目,从而保证在组播预览时间到时, ONU自动断开组 播数据流, 实现对组播数据流的预览功能。 需要注意的是, 预定预览时间需要短于 RFC 2236协议规定的组播地址 默认老化时间, 且观看预览条目时收到新的组播 join报文后其预览剩余时间 不受新的组播 join报文的影响, 即不会像正常组播白名单组播地址转发条目 那样在收到新的组播 join报文会重新刷新。 由此可避免预览用户通过反复点 击终端上的预览功能而多次得到预览内容观看。
本发明针对上述方法实施例, 相应地提出实现光网络单元组播预览功能 的系统, 包括一个 OLT和该 OLT下挂的一个或多个 ONU , 其中: OLT, 其设置为: 在完成 ONU注册及其它端口初始化配置后, 命令相 应的 ONU创建组播操作实体;在收到 ONU返回的创建组播操作实体响应后, 向该 ONU下发组播数据流。 OLT在下发的命令中指明需要 ONU创建的组播操作实体及要配置的组 播频道列表。 其中, 对于允许观看的白名单组播频道, 组播频道列表中相应 的组播频道条目的 Reserved字段配置为 0; 对于属于组播预览的组播频道, 相应的组播频道条目的 Reserved字段的最低位(bit ) 置为 1。 ONU, 其设置为: 在收到 OLT下发的命令后, 设置对应的 ME, 并将配 置数据存储到本地数据库中; 在完成白名单组播频道项和预览组播频道项配 置后,根据白名单组播频道项和预览组播频道项生成相应的组播地址转发项, 向 OLT返回创建组播操作实体响应。
ONU收到 OLT下发的组播数据流后, 按相应的组播地址转发项转发组 播数据流; 针对组播白名单频道和组播预览频道对下游设备发送的报文进行 相应处理。 区别处理的内容前已述及, 此不再赘述。
如图 2所示, 是本发明提供的实现组播预览功能的光网络单元装置实施 例, 包括依次连接的命令解析处理模块、 组播协议模块以及组播地址转发模 块, 其中: 命令解析处理模块, 其设置为: 依据 OMCI协议解析 OLT下发的创建 组播操作实体命令, 设置对应的 ME, 将合法命令中的配置数据存储到数据 库(图中未示) 中, 同时指示组播协议模块配置组播频道项; 组播协议模块, 其设置为: 根据命令解析处理模块的指示和数据库中保 存的配置数据, 配置白名单组播频道项和预览组播频道项, 并输出给组播地 址转发模块; 在完成预览组播频道项和白名单组播频道项的配置后, 向光线 路终端返回创建组播操作实体响应; 组播地址转发模块, 其设置为: 根据组播协议模块输出的白名单组播频 道项和预览组播频道项生成相应的组播地址转发项;在收到 OLT下发的组播 数据流后, 按相应的组播地址转发项转发组播数据流。
ONU在处理下游设备发送的 IGMP join报文时,针对组播白名单频道和 组播预览频道对"^艮文进行区别处理。 区别处理的内容前已述及,此不再赘述。 本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成, 所述程序可以存储于计算机可读存储介质中, 如只读 存储器、 磁盘或光盘等。 可选地, 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地, 上述实施例中的各模块可以釆用硬件 的形式实现, 也可以釆用软件功能模块的形式实现。 本发明不限制于任何特 定形式的硬件和软件的结合。
工业实用性 本发明通过定义一种简单有效的 ME的功能扩展来实现光网络单元组播 预览功能, 故能够规范 GPON系统的互通测试, 提高互通测试的效率, 从而 对于 GPON系统中的 OLT及 ONU产品的技术发展具有极大的推动作用。
