光传送网络( Optical Transport Network , 以下简称: ΟΤΝ )作为下一代 传送网的核心技术, 具备丰富的运行、 管理、 维护 ( Operation Administrator Maintenance, 以下简称: OAM )能力, 能够实现大容量业务的灵活调度和管 理, 日益成为骨干传送网的主流技术。
以太网需要使用光传送网承载以太网信号来进行信号传输 , 实现大容量、 长距离传送信息的要求。 基于技术成熟度和成本的现状, OTN线路的承载能 力有限。 当单个 OTN线路的带宽不足以承载以太网数据流量时, 可以采用虚 级联的方式, 将多个 OTN线路组合起来提供更大的带宽, 以完成数据的传送。 比如在 lOGbps带宽级别的 OTN中,使用 OPU2( Optical Channel Payload Unit-2, 以下简称: 光通道净荷单元 2 )级别的容器, 最多装下 lOGbps的数据信息。 如 果需要传送 40Gbps的数据, 则可以采用虚级联技术将 4个 OPU2级别容器组合 起来形成 OPU2-4V ( 4 virtually concatenated OPU2s , 以下简称: 4个光通道净 荷单元 2虚级联) 容器, 承载 40Gbps的带宽。 将以太网数据封装到 4个 OPU2 容器, 并在每个 OPU2容器中增加相应的虚级联标志信息, 然后分装成 4路独 立的 OTU2 ( Optical Channel Transport Unit-2, 以下简称: 光通道传送单元 2 ) 帧, 通过 4个独立的 OTN线路进行传送。 在接收端, 将收到的 4路独立的帧进 行解帧操作后, 得到 4个 OPU2容器, 通过识别虚级联标志信息将这 4个 OPU2 容器组装形成 OPU2-4V容器, 进行解封装后得到正确的数据。
OTN采用虚级联技术承载以太网信号的方案, 通常会有以下需求:
1.当 OTN发生部分线路故障时, 要求以太网也能相应的进行流量的调整。 比如某条 OTN线路发生了故障, 相应的通道就不能正确的传输数据, 此时需 要以太网设备减少数据流量以保证数据的正常传输。 因为以太网数据是多通 道并行传输的, 各通道间数据是相互关联的, 当部分通道出现故障后, 其他 通道就不能组合出正确的数据, 导致以太网数据传输失效。 因此需要以太网 降低流量, 使信号在可用的通道上进行传输。
2.当以太网设备的数据流量进行调整时, 要求 OTN也能相应的进行线路 的调整, 节约 OTN线路资源。
现有技术的方案如图 1所示, 图 1是现有技术提供的支持 OTN线路容量调 整的框架示意图, 以太网数据经过接收单元处理后, 传递到封装单元, 由封 装单元根据速率等级将以太网信号封装到虚级联容器中,如以 OPU2的速率级 别将信号封装到虚级联容器中。 然后将封装的数据进行成帧操作, 生成可以 在 OTN线路上传递的 OTU格式信号, 由 OTN线路发送单元对 OTU信号进行光 信号的转换后在光纤上进行传输。 在现有技术中, 通过链路容量调整(Link Capacity Adjust Scheme, 以下简称: LCAS )模块与封装单元、 解封装单元、 虚级联成帧 /解帧单元和以太网线路收发单元进行交互, 可以实现 OTN的动态 线路调整和部分线路的失效保护。
在对现有技术进行研究后, 发明人发现, 现有技术中, 动态线路调整及 部分线路的故障保护功能都只在 OTN生效, 无法和以太网设备进行交互, 当 部分 OTN线路发生故障导致相应通道不可用时,不能及时通告以太网设备减 小数据流量, 致使多通道的数据不能组合出正确的数据, 导致以太网数据传 输失效。 而当以太网设备进行流量调整时, OTN也不能进行相应的调整, 比 如当以太网数据流量降低时, OTN依然提供较大的带宽, 造成资源浪费。 发明内容 施例提供了一种传送网络数据传输调整的方法和装置。 所述技术方案如下: 一种传送网络数据传输调整的方法, 所述方法包括:
接收光传送网络 OTN发送的调整指定 OTN线路的信息;

具体的, 当 OTN需要关闭部分指定的 OTN线路时, 向 LCAS模块 301发送 关闭该指定 OTN线路的信息, LCAS模块 301接收到该关闭指定 OTN线路信息 后, 获取需要调整关闭的 OTN线路, 并关闭该需要调整关闭的 OTN线路, 即 通过与 OTN进行协商, 删除该 OTN线路上的虚级联容器; 相应的, 当 OTN需 要开启部分指定的 OTN线路时, 向 LCAS模块 301发送开启该指定 OTN线路的 信息, LCAS模块 301接收到该开启指定 OTN线路信息后, 获取需要调整开启 的 OTN线路, 并开启该 OTN线路, 即通过与 OTN进行协商, 添加该 OTN线路 上的虚级联容器。
进一步的, 通道处理模块 302包括: 通道控制单元 302a、 第一通道处理单 元 302b、 第二通道处理单元 302c。 在本发明实施例中, 按照以太网信号的接 收和发送, 将通道处理单元分为接收方向的第一通道处理单元 302b, 以及发 送方向的第二通道处理单元 302c , 两个通道处理单元由通道控制单元 302a进 行控制。
通道控制单元 302a, 用于当该变化的数据流量为减少的数据流量时, 根 据该减少的数据流量指定需要关闭的以太网通道, 并向第一通道处理单元 302b和第二通道处理单元 302c发送关闭该需要关闭的以太网通道的控制信 息; 当该变化的数据流量为增加的数据流量时, 根据该增加的数据流量指定 需要开启的以太网通道, 并向第一通道处理单元 302b和第二通道处理单元 302c发送开启该需要开启的以太网通道的控制信息;

例如, 正常情况下 10个 lOGbps以太网信号由 10条 OTN线路承载, 即 封装单元将输入的 10个 lOGbps以太网信号封装到 10个虚级联容器中,封装 的是通道 1〜通道 10中的数据。 当有 4个虚级联容器发生故障时, OTN线路 总体的承载量降低为 60Gbps, 需要以太网设备也相应的减少数据流量。 当以 太网设备的数据流量相应降低, 并将数据在通道 1〜通道 6上传输时, LCAS 模块 301会向封装单元发送虚级联容器大小为 60Gbps的信息, 以及对通道 1〜通道 6上的数据进行封装的控制信息, 封装单元收到控制信息后, 将通道 1〜通道 6上的数据封装到 6个虚级联容器中。 对数据进行解封装处理的原理 与此相同, 不再赘述。

实施例 5
本发明实施例提供了一种传送网络数据传输调整的方法, 该方法用于当 OTN对 OTN线路进行了调整时, 请求以太网设备对以太网通道也进行相应 的调整, 参见图 5, 图 5是本发明实施例 5提供的传送网络数据传输调整 的方法的流程图, 具体步骤为:
501 : 接收光传送网络 OTN发送的调整指定 OTN线路的信息。
502: 对该调整指定 OTN线路的信息对应的 OTN线路进行调整。
具体可以为, 当接收到 OTN发送的关闭指定的 OTN线路的信息时, 则关 闭该指定的 OTN线路, 即删除该 OTN线路上的虚级联容器; 相应的, 当接收 到 OTN发送的开启指定的 OTN线路的信息时, 则开启该指定的 OTN线路, 即 在该 OTN线路上的添加虚级联容器。
503: 计算进行调整后的所述 OTN线路的变化的数据流量。
具体可以为, 当 OTN发送的信息为关闭指定 OTN线路的信息时, 则根据 该关闭指定 OTN线路的信息, 计算关闭该指定 OTN线路所减少的数据流量; 相应的, 当 OTN发送的信息为开启指定 OTN线路的信息时, 则根据该开启指 定 OTN线路的信息, 计算开启该指定 ΟΤΝ线路所增加的数据流量。

进一步的, 当指定需要关闭的以太网通道时, 应确保关闭该以太网通道 减少的数据流量大于 ΟΤΝ中减少的数据流量, 比如, ΟΤΝ中减少的数据流量 为 40Gbps, 当单以太网通道的数据流量是 lOGbps时, 减少 4条以太网通道即 可, 而当单以太网通道数据的数据流量是 25Gbps时, 需要减少两条以太网通 道以保证数据的正常传输。 相应的, 当指定需要开启的以太网通道时, 也应 确保开启该以太网通道所增加的数据流量小于 OTN增加的数据流量。 其中, 指定需要调整的以太网通道时, 可以随机的指定, 也可以预先对以太网通道 设置优先级, 根据优先级指定需要调整的以太网通道。
对该需要调整的以太网通道进行相应的调整。 具体的, 当指定的需要调 整的以太网通道为需要关闭的以太网通道时, 则停止对该需要调整的以太网 通道上的数据进行发送, 并在该需要调整的以太网通道上插入标识信息, 指 示以太网设备不在该需要调整的以太网通道上传输数据; 相应的, 当指定的 需要调整的以太网通道为需要开启的以太网通道时, 则开始对该需要调整的 以太网通道上的数据进行发送, 并在该需要调整的以太网通道上插入标识信 息, 指示以太网设备在该需要调整的以太网通道上传输数据。
由于以太网数据的流量是双向的, 当有 OTN线路需要关闭或开启时, 需 要以太网设备双向关闭或开启指定的以太网通道, 即同时关闭或开启该以太 网通道上数据的输入和输出。
在 OTN线路调整和以太网通道调整结束后,以太网设备在调整后的以太 网通道上传输数据; OTN根据调整后的以太网通道和 OTN线路总容量, 对 传输的数据进行封装和解封装等处理。

相应的, 当接收到的调整指定以太网通道的信息为开启指定以太网通道 的信息时, 根据该信息, 获取需要调整开启的以太网通道, 开始对该需要调 整开启的以太网通道中的数据进行发送。 同时在该以太网通道上插入标识信 息, 指示以太网设备在该以太网通道上传输数据。
603: 计算进行调整后的所述以太网通道的变化的数据流量。
具体的, 当以太网设备发送的信息为关闭指定以太网通道的信息时, 根 据该关闭指定以太网通道的信息,计算关闭该以太网通道所减少的数据流量; 相应的, 当以太网设备发送的信息为开启指定以太网通道的信息时, 根据该 开启指定以太网通道的信息, 计算开启该以太网通道所增加的数据流量。
604: 根据该变化的数据流量指定需要调整的 OTN线路, 并对该需要调整 的 OTN线路进行相应的调整。
具体的, 当该变化的数据流量的信息为减小的数据流量的信息时, 则根 据减小的数据流量, 与 OTN进行协商, 指定需要关闭的 OTN线路, 并关闭该 OTN线路, 即删除该 OTN线路上的虚级联容器。 相应的, 当该变化的数据流 量的信息为增加的数据流量的信息时, 则根据增加的数据流量, 与 OTN进行 协商, 指定需要开启的 OTN线路, 并开启该 OTN线路, 即在该 OTN线路上的 增加虚级联容器。
进一步的, 当指定需要关闭的 OTN线路时, 应确保关闭该 OTN线路所减 少的数据流量小于以太网设备减少的数据流量, 以保证以太网信号有足够的 OTN线路进行承载; 当指定需要开启的 OTN线路时, 应确保开启该 OTN线路 所增加的数据流量大于以太网设备增加的数据流量。
其中, OTN关闭或开启 OTN线路是双向的, 即同时关闭或开启该 OTN线 路的输入和输出。
