具体实施方式
下面结合附图及实施例对本申请再作进一步详细的描述。
相关技术中，传统OTN网络(即OTN系统)为承载10Mbps至10Gbps的小颗粒(即小带宽)引入了光业务单元(OSU，Optical Service Unit)机制，该机制也可以称为Sub-1G、或者fgOTN(fine grain OTN)机制。此时，OTN系统的映射机制如图1所示，业务(即业务数据)传输至支持OSU机制的OTN设备后，OTN设备先将业务映射到OSU帧(或Sub-1G帧、或小颗粒ODU(fine grain ODU，fgODU)帧、或小颗粒灵活ODU(fine grain ODU flexible，fgODUflex)帧)中，将OSU帧(或fgODUflex帧、或fgODU帧)封装到光载荷单元(OPU，Optical Payload Unit)帧，将OPU帧封装到光通道数据单元(ODU，Optical channel Data Unit)帧，再将ODU帧封装到光转换单元(OTU，Optical Transform Unit)帧。其中，OTN设备将OSU帧(或fgODUflex帧、或fgODU帧)封装到OPU帧时，可以先将OSU帧(或fgODUflex帧、或fgODU帧)映射到光业务时隙单元或光业务支路单元(OSTU，Optical Service Tributary Unit)帧(或细颗粒光数据支路单元(fine grain Optical Data Tributary Unit，fgODTU)帧)中，再将OSTU帧(或fgODTU帧)复用到OPU帧。
然而，如果OSU帧(即Sub-1G帧)采用图2所示的4*3824的传统OTN帧结构，可能会存在以下问题：
问题1，仅第1列至第16列为OSU帧的开销，开销出现的频率(也可以理解为开销重复的频率)无法满足OTN系统中保护倒换时间的性能；换句话说，OSU帧中开销出现的频率不够，导致保护倒换时间的性能不足；
问题2，OSU帧的开销仅包含一个FAS，FAS的数量无法满足OSU帧的定位需求；换句话说，FAS数量不够，导致OSU帧定位慢；
问题3，OSU帧的开销仅包含一个MFAS，MFAS的数量无法满足OSU帧的复帧定位需求；
问题4，OSU帧的开销仅有1个比特用于延时测量(DM，Delay Measurement)功能，当测量时延时，源端(即发送端)将这个DM比特从0翻转为1后发送给宿端(即接收端)，宿端再将这个DM信息(即DM比特)返回给源端，源端接收到DM信息后，计算从发送这个DM信息到接收这个DM信息之间的帧周期的数量乘以帧频率，得到往返延时结果(即时延测量结果)；由于每个帧的传输时间是动态变化的，所以这种时延测量方式的精度受限。
从上面的描述可以看出，相关技术中的OTN帧结构可能无法满足小带宽业务的数据处理需求；换句话说，由于OSU机制(即Sub-1G)的性能需求，OSU帧(即Sub-1G帧)需要新的帧结构和/或帧开销。
基于此，针对上述问题1，在本申请的各种实施例中，在OTN系统中定义了承载业务数据的新的OSU帧(即Sub-1G帧)，对于小带宽业务(比如数据传输速率在10Mbps至10Gbps范围内的业务)，通过增加帧开销或缩短帧长的方式，提高OSU帧的帧结构中开销出现的频率，由于帧结构中开销出现的频率与OTN系统进行保护倒换的时间关联，从而能够缩短OTN系统进行保护倒换的时间，从而能够提高业务数据的处理效率，即提高业务数据的传输效率。
针对上述问题2，在本申请的各种实施例中，OSU帧(即Sub-1G帧)的帧结构中的每行均包含至少一个FAS，从而实现了在OSU帧结构中增加FAS的数量，从而能够提高OSU帧的定位速度。
针对上述问题3，在本申请的各种实施例中，OSU帧(即Sub-1G帧)的帧结构中的每行均包含至少一个MFAS，从而实现了在OSU帧结构中增加MFAS的数量，从而能够提高OSU帧的复帧定位速度。
针对上述问题4，在本申请的各种实施例中，在OTN系统中针对单向延时测量(1DM，one-way Delay Measurement)定义了新的包含时间戳的DM信息，如此，后续能够基于时间戳实现单向时延测量，从而能够提高单向时延测量的精度。
针对上述问题4，在本申请的各种实施例中，在OTN系统中针对双向延时测量(2DM，two-way Delay Measurement)定义了新的包含时间戳的DM信息，如此，后续能够基于时间戳实现双向时延测量，从而能够提高双向时延测量的精度。
需要说明的是，在本申请的各种实施例中，各种业务(第一业务、第二业务、第三业务、第四业务、第五业务)可以是相同的业务，也可以是不同的业务。这些业务可以包括小带宽业务，比如数据传输速率在10Mbps至10Gbps范围内的业务。并且，这些业务的类型可以包括固定速率(CBR，Constant Bit Rate)业务，比如同步传送模式(STM)-N业务等，所述STM-N业务可以包含STM-1、STM-4、STM-16、STM-64等；或者，这些业务的类型可以包括变速率(VBR，Variable Bit Rate)业务，比如分组业务等。另外，对这些业务的相关处理，可以理解为对业务数据的相关处理。
在本申请的各种实施例中，承载业务数据的各种帧(第一帧、第二帧、第三帧、第四帧、第五帧、第六帧)可以是相同的帧，也可以是不同的帧。这些帧可以理解为用于承载业务数据的容器，这些帧也可以称为容器、OSU帧、OSU容器、Sub-1G帧、Sub-1G容器等，本申请实施例对这些帧的名称不作限定，只要实现其功能即可。
在本申请的各种实施例中，发送端设备与接收端设备进行各种帧(第一帧、第二帧、第三帧、第四帧、第五帧、第六帧)的传输时，可以先将这些帧通过预设的中间步骤封装到OSTU帧中，然后将OSTU帧封装到OPU帧和/或ODU帧，再进行OPU帧和/或ODU帧的传输。其中，OPU帧可以包括OPUflex帧、OPU0帧、OPU1帧、OPU2帧、OPU3帧、OPU4帧等。
在本申请的各种实施例中，发送端设备可以包括光通信设备，具体可以包括OTN设备等；相应地，接收端设备也可以包括光通信设备，具体可以包括OTN设备等；所述发送端设备和接收端设备的具体类型可以根据需求来设置，本申请实施例对此不作限定。另外，发送端设备也可以称为源端设备、源节点(英文可以表达为Source Node)等；接收端设备也可以称为宿端设备、宿节点(英文可以表达为Sink Node)等；本申请实施例对发送端设备和接收端设备的名称也不作限定，只要实现其功能即可。
