Description

一种数据发送方法、接收方法、发送装置和接收装置 技术领域
本申请涉及通信领域，尤其涉及一种数据发送方法、接收方法、发送装置和接收装置。
背景技术
用于在过去十年中，网络业务流量一直保持高速增长，促使通讯设备的业务带宽快速增长，通讯设备的接口速度从10M带宽提高到100M，再提高1G、10G，每隔几年业务速度就翻几倍，以适应网路上业务流量的需求。目前通讯设备为了满足业务的传递需求，国际标准组织定义了IEEE802.3以太网协议。IEEE802.3以太网协议提出将多个100G的物理通道捆绑起来，形成一个大业务速度的传递通道，如图1所示，该图所示为IEEE802.3以太网协议的通用结构示意图，通过FlexE协议将N个25G的物理通道捆绑起来，形成一个N*25G传递通道，等效于N*25G个物理通道的业务传递速度，既满足了N*25G业务的传递需求，也解决了业务传递的经济价值问题。以太网组指的是将一个Ethernet PHY拆分成N个物理通道的一个组。其中，以太网组中两端的成员之间的物理通道构成一条通信链路，其中由于IEEE802.3以太网协议是将多个物理通道捆绑成一个业务传递的逻辑通道，当一个物理通道发生故障时，则整个逻辑通道都发生故障，如一个物理通道中断，则整个逻辑通道都中断了。因此，目前的灵活以太网当在收发任一方向上的物理通道中断时，对端成员则无法通过多个物理通道捆绑的逻辑通道接收到数据，工作可靠性低。
发明内容
本申请实施例提供一种数据发送方法、接收方法、发送装置和接收装置，用以提高以太网传输数据的可靠性。
第一方面，本申请实施例提供一种数据发送方法，包括：发送设备在多个物理通道中确定出多个未发生故障的物理通道；发送设备将待发送的数据拆分和编码，得到多个编码后的数据段；发送设备将多个编码后的数据段通过多个未发生故障的物理通道进行传输。
采用上述方法，由于将待发送的数据拆分为多个数据段，并对拆分的数据段分别进行编码，每一个编码后的数据段作为单独的数据进行传输，此时当用于传输数据段的一个或多个物理通道发生故障时，可以将利用未发生故障的物理通道进行传输，从而保证接收设备可以接收完整性的待发送数据，提高了灵活以太网组传输数据的可靠性。
在一种可能的设计中，发送设备将待发送的数据拆分和编码，包括：发送设备将待发送的数据拆分为多个长度相同的数据段，并分别对每一个数据段进行编码。
采用上述方法，在确定物理通道发生故障，采用未发生故障中的物理通道传输数据段时，由于每个数据段的长度相同，在采用未发生故障的物理通道进行数据传输时，该数据段的编码方式未发生变化，从而提高了数据传输的便利。

采用上述方法，由于发送设备通过多个未发生故障的物理通道将待发送数据发送给接收设备，接收设备可以从多个未发生故障的物理通道中接收到多个数据段，即可得到完整的数据，并对接收的多个数据段进行解码后进行重组即可得到接收数据，保证了接收设备接收数据的完整性，提高了以太网传输数据的可靠性。
在一种可能的设计中，接收设备从多个未发生故障的物理通道接收多个数据段，包括：接收设备从多个未发生故障的物理通道接收多个长度相同的数据段。
采用上述方法，在确定物理通道发生故障时，接收设备从未发生故障的物理通道中接收数据段时，由于每个数据段的长度相同，在对该数据段进行解码时，数据段的解码方式未发生变化，从而提高了数据处理的效率。

采用上述方法，由于单个物理通道的传输速率有限，当数据段需要的传输速率的需求较高时，可以通过将多个物理通道进行捆绑的形式，来提高数据段的传输速率，以满足传输速率要求。
在一种可能的设计中，根据第二数据段需要的传输速率，通过至少一个未发生故障的物理通道接收第二数据段，包括：确定每一个物理通道的传输速率；根据第二数据段需要的传输速率与每一物理通道的传输速率的比值，确定用于传输第二数据段的至少一个物理通道，通过至少一个物理通道接收第二数据段。

附图说明

图2为本申请实施例提供的一种数据发送方法和接收方法的流程示意图；
图3为本申请实施例提供的一种待发送数据的传输示意图一；
图4为本申请实施例提供的一种待发送数据的传输示意图二；

图7为本申请实施例提供的一种数据接收装置的结构示意图。
具体实施方式
图1为本申请实施例适用的一种可能的以太网系统的架构示意图。具体的，如图1所示的灵活以太网系统架构包括传输设备1(图1中以PHY1表示)、传输设备2(图1中以PHY2表示)以及传输设备1和传输设备2之间用于传输数据的N条物理传输通道，其中 传输设备1和传输设备2均支持IEEE802.3以太网协议。
若使用IEEE802.3以太网协议实现将N个物理通道捆绑成一个大逻辑通道，在通过IEEE802.3以太网协议发送数据时，传输设备1将待发送数据进行编码并拆分成N个数据段，并将拆分的N个数据段中的第一个数据段发送到第一个物理通道上，将第二个数据段发送到第二个物理通道上，以此类推，将第N个数据段发送到第N个物理通道上。接收数据时，传输设备2从第一个物理通道中接收第一个数据段，从第二个物理通道中接收第二个数据段，以此类推，从第N个物理通道中接收第N个数据段，并将接收的N个数据段进行重组后解码。
在通过IEEE802.3以太网协议实现将N个物理通道捆绑成一个大逻辑通道时，待发送数据的传输速率为每一个物理通道上传输的数据段的传输速率之和，因此提高了待发送数据的传输速率，但是在此种方式下进行数据传输时，一旦用于传输数据的N个物理通道中的任意一个或多个物理通道发生故障时，传输设备2就将无法接收到完整的数据段，而传输设备2接收不到完整的数据，则无法对重组后的数据进行解码处理，从而造成数据传输失败。
基于此，本申请实施例提供了一种数据发送方法、接收方法、发送装置和接收装置，用以解决上述在IEEE802.3以太网协议下若传输路径上的一个或者多个物理通道故障所导致的数据传输失败，无法进行正常业务传输的问题。
下面结合附图对本申请提供的数据发送方案进行具体说明。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。需要说明的是，在本申请的描述中“至少一个”是指一个或多个，其中，多个是指两个或两个以上。鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
参见图2，为本申请提供的一种数据发送方法和接收方法的流程示意图。其中，该数据发送方法由传输设备1中设置的支持IEEE802.3以太网协议的发送设备实现，该数据接收方法由传输设备2中设置的支持IEEE802.3以太网协议的接收设备实现，具体地，该数据发送方法和接收方法主要包括以下步骤：
S201、发送设备将测试数据通过多个物理通道发送给接收设备。
具体实施时，在将测试数据通过多个物理通道发送给接收设备时，可以将测试数据直接通过多个物理通道分别发送给接收设备。
可选地，为了减小数据传输量，也可以将测试数据拆分为与多个物理通道数量相同的多个测试字段，并将多个测试字段与多个物理通道一一对应，将多个测试字段中的每一个测试字段通过对应的物理通道发送给接收设备。
S202、接收设备确定每一个物理通道接收测试数据的情况。
具体地，接收设备从对应的物理通道中接收测试数据，并根据每一个通道中接收测试数据的情况，确定每一个物理通道的状态信息(故障状态和未故障状态)。
S203、接收设备根据每一个物理通道接收测试数据的情况向发送设备发送测试数据的反馈。
S204：发送设备根据接收设备对测试数据的反馈，在多个物理通道中确定出多个未发送故障的物理通道。
S205：发送设备将待发送数据拆分和编码，得到多个编码后的数据段。发送设备拆分的数据段的数量可以小于或者等于多个未发生故障的物理通道的数量。
可选地，发送设备将待发送数据拆分为多个长度相同的数据段，并对每一个数据段进行编码，得到多个编码后的数据段。
在将待发送数据进行拆分之前，先对待发送数据进行64/66转换，将64比特的数据块扩展为66比特的信息块。IEEE802.3以太网协议处于64比特到66块转换层，对66比特的数据块进行排序和拆分。以25G的业务为例，将待发送数据拆分为多个66比特的数据块，每4个66比特数据块划分为一个数据块组(数据段)，每一个数据块组为257比特的数据块。
在将待发送数据拆分为多个数据段之后，分别对多个数据段进行前向纠错(Forward Error Correction，简称FEC)编码之前，对每一个数据块组进行加扰处理，并以Y数据块组为间隔插入一个对齐开销块(AM alignmark)，插入对齐开销块后，并对该数据段进行FEC编码，再插入对齐开销块，以此类推，这样会周期性地插入对齐开销块，相邻两个对齐开销块的间隔是Y*257比特的数据块。其中，Y为大于1的正整数。
S206、发送设备将多个编码后的数据段通过多个未发生故障的物理通道发送给接收设备。
当使用IEEE802.3以太网协议将多个未发生故障的物理通道捆绑成一个大逻辑通道时，发送设备将待发送数据拆分和编码，得到多个编码后的数据段，并将多个未发生故障的物理通道捆绑成一个大逻辑通道。发送设备发送待发送数据时，可以将编码后的第一个数据块组(第一个数据段)发送到第一个物理通道上，第二个数据块组(第二个数据段)发送到第二个物理通道上，以此类推，将所有的数据块组平均、轮询地发送给多个物理通道上，也可以将最后一个数据块组发送到第一个物理通道中，将第倒数第二个数据块组发送到第二个物理通道中，以此类推，将所有的数据块组平均、轮询地发送给多个物理通道上。多个物理通道上的数据块组在发送时是完全对齐的，通过这种方式可以将多个物理通道捆绑起来，组成一个大的逻辑通道。
需要说明的是，本申请实施例中的数据发送方法与现有技术中通过IEEE802.3以太网的数据传输方法的区别在于：本申请实施例中的待发送数据在确定物理通道发生故障时，可以将待发送数据通过未发生故障的物理通道进行传输，从而保证接收设备可以接收到完整的数据，从而实现在提高数据传输速率的同时，解决了由于某一个物理通道发生故障所造成的数据传输失败的问题，且由于拆分的每一个数据段的长度相同，即每一个数据段的编码方式相同，当某一个物理通道发生故障，采用其它的物理通道进行传输时，对数据段可以直接进行编码，数据处理简便快捷。
可选地，在通过多个未发生故障的物理通道传输多个编码后的数据段时，若数据段需要的传输速率较高，而单个物理通道的传输速率有限，发送设备在将多个编码后的数据段通过多个未发生故障的物理通道进行传输时，发送设备可以首先确定编码后的数据段中的第一数据段需要的传输速率，并根据第一数据段需要的传输速率，通过至少一个未发生故障的物理通道发送第一数据段。其中，第一数据段可以为多个编码后的数据段中的任意一个数据段。
具体地，在根据第一数据段需要的传输速率，通过至少一个未发生故障的物理通道发送第一数据段时，首先确定每一个物理通道的传输速率，然后根据第一数据段需要的传输速率与每一个物理通道的传输速率的比值，确定用于传输第一数据段的至少一个物理通道，通过至少一个物理通道发送第一数据段。
例如，以每一个物理通道的传输速率为25Gbps为例，若第一数据段需要的传输速率为50Gbps，则需要两个物理通道传输第一数据段，即可满足第一数据段需要的传输速率。
具体的，在通过多个物理通道传输第一数据段时，将第一数据段拆分为多个子数据段，并将多个子数据段通过多个物理通道传输。
S207：接收设备从多个未发生故障的物理通道接收多个数据段。其中，数据段的数量可以小于或者等于多个未发生故障的物理通道的数量。
可选地，接收设备从多个未发生故障的物理通道中接收多个长度相同的数据段。
具体地，当使用IEEE802.3以太网协议将多个未发生故障的物理通道捆绑成一个大逻辑通道时，接收设备将多个未发生故障的物理通道捆绑成一个逻辑通道，并从多个未发生故障的物理通道中多个数据段。接收设备接收多个数据段时，可以从第一个物理通道上接收第一个数据块组(第一个数据段)，从第二个物理通道上接收第二个数据块组(第二个数据段)，以此类推，从多个未发生故障的物理通道中接收多个数据段，通过这种方式可以将多个未发生故障的物理通道捆绑起来，组成一个大的逻辑通道。
可选地，在通过多个未发生故障的物理通道接收多个数据段时，若数据段需要的传输速率较高时，而单个物理通道的传输速率有限，接收设备在通过多个未发生故障的物理通道接收多个数据段时，接收设备确定多个数据段中的第二数据段需要的传输速率，并根据第二数据段需要的传输速率，通过至少一个未发生故障的物理通道接收第二数据段。其中，第二数据段可以为多个数据段中的任意一个数据段。
具体地，在根据第二数据段需要的传输速率，通过至少一个未发生故障的物理通道接收第二数据段时，首先确定每一个物理通道的传输速率，然后根据第二数据段需要的传输速率与每一个物理通道的传输速率的比值，确定用于传输第二数据段的至少一个物理通道，通过至少一个物理通道接收第二数据段。
其中，在通过多个物理通道接收第二数据段时，从多个物理通道中接收多个数据段，并将获取的多个数据段进行重组，得到第二数据段。
S208：接收设备将多个数据段进行解码，得到多个解码后的数据段，并分别对多个解码后的数据段进行重组，得到接收的数据。
在对多个数据段进行解码之前，将接收的多个数据段进行对齐开销块对齐，并基于对齐的开销块的位置为基准，对齐多个数据块段，并基于对齐的数据段进行FEC解码处理。
其中，在将多个解码后的数据段进行重组时，将多个解码后的数据段进行解扰处理，将多个解扰处理后的数据段转换为257比特的数据块，并将多个257比特的数据块转换为66比特的数据块，并将多个转换为66比特的数据段进行重组。
需要说明的是，本申请实施例中的数据接收方法与现有技术中通过IEEE802.3以太网的数据传输方法的区别在于：本申请实施例中的待发送数据在确定物理通道发生故障时，可以将待发送传输通过未发生故障的物理通道进行传输，接收设备也可以从未发生故障的物理通道上接收发送设备发送的待发送数据，得到完整的接收数据，从而解决了由于某一个物理通道发生故障所造成的数据传输失败的问题，且由于每一个数据段的长度相同，即 每一个数据段的编码和解码方式相同，当某一个物理通道发生故障，采用其它的物理通道进行传输时，接收设备可以对数据段直接进行解码，数据处理简便快捷。
下面结合实施例对本申请的提供的数据发送方法和接收方法进行详细说明。

接收设备通过16个未发生故障的物理通道接收待发送数据。具体地，先从第一物理通道接收第一个数据块组，从第二个物理通道中接收第二个数据块组，以此类推，从第十六个物理通道中接收第十六个数据块组，分别对接收的数据块组进行对齐开销块锁定，并以锁定的对齐开销块的位置为基准，对齐十六个数据块组，将对齐后的数据块组分别进行FEC解码处理，对FEC解码后的16个数据块组进行解扰处理，将解扰后的16个数据块组分别转换为257比特的数据块，并将16个257比特的数据块分别转换为66比特的数据块，并将转换为66比特的16个数据块进行重组，得到接收数据。

具体实施时，接收设备从第一个物理通道和第二个物理通道接收第一个数据块组时，从第一个物理通道中接收第一数据块组的第一个子数据段，从第二个物理通道中接收第一数据块组的第二个子数据段，将第一子数据段和第二子数据段重组得到第二数据块组。
实施例三
参见图5所示，为本申请实施例提供的一种待发送数据的传输过程示意图。具体地。待发送数据的传输速率为400Gbps，未发生故障的物理通道的数量为16个，每一个物理通道的传输速率为25Gbps。若将待发送数据拆分为4个数据段，则每一个数据段需要的传输速率需求为100Gbps，可以通过四个未发生故障的物理通道传输一个数据段。
发送设备首先将待发送数据由64比特转换为66比特，并将转换为66比特的待发送数据拆分为4*4个66比特的数据块，每4个数据块组成一个数据块组(每一个数据块组为257比特的数据块)，对每一个数据块组进行加扰处理，并插入对齐开销块，分别对拆分的4个数据块组进行FEC编码处理，将第一个数据块组发送到第一个物理通道、第二个物理通道、第三个物理通道和第四个物理通道上，将第二数据块组发送到第五个物理通道、第六个物理通道、第七个物理通道和第八个物理通道上，将第三数据块组发送到第九个物理通道、第十个物理通道、第十一个物理通道和第十二个物理通道上，将第四个数据块组发送到第十三个物理通道、第十四个物理通道、第十五个物理通道和第十六个物理通道上。
