一种调节光信道中流量分布的方法和电子设备 技术领域
本申请实施例涉及光纤通信领域,尤其涉及一种调节光信道中流量分布的方法和电子设备。
背景技术
参考图1,以发送侧为例,从信源输出的业务数据经过前向纠错(forward error correction,FEC)编码后,会先映射为符号数据,下游的数字信号处理(digital signal processing,DSP)模块将这些符号数据作为一个整体进行处理,最终经过数模转换器(digital to analog converter,DAC)和光器件调制到合适的光载波上。因此,DSP部分的补偿是基于整体光信道进行补偿的。
然而,上述方案中的DSP补偿是基于一些已知的劣化(如色散、器件老化)进行补偿的,但实际上光器件引入的劣化往往大于预期,且伴随着一些难以分析的非线性效应,这使得补偿的效果不甚理想。通常,DSP的补偿可以削弱各种劣化带来的影响,却不能完全消除。因此,补偿后的光信道仍然呈现出不平坦的特性,数据在这样的光信道中进行传输不能达到最佳的匹配效果,降低了系统的整体性能。

具体实施方式

以下,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
本申请的技术方案可以应用于光纤通信中,光纤通信是一种使用光纤作为传输介质的先进通信系统。由于光纤具有信号衰减小、可利用的带宽大的特点,使得光纤通信成为长距离大容量传输应用的首选方式。但是我们用于传输数据的光信道不是完全平坦的。受到光器件的影响,在光信道的不同区域会存在不同程度的衰减,如何更加有效地利用光信道的这种特征来传输数据,成为亟待解决的问题。当前主流的光数字信号处理(optical digital signal processing,ODSP)芯片是将符号数据作为一个整体,经过处理后调制到光载波上。考虑到光器件的非线性会导致光信道的不平坦,目前常见的做法是在收发端进行补偿,使光信道的特征更接近于理想的信道。
如图1所示,为本申请实施例提供的一种系统框图。
参考图1,以发送侧为例,从信源输出的业务数据经过FEC编码后,会先映射为符号数据,下游的DSP模块将这些符号数据作为一个整体进行处理,最终经过DAC和光器件调制到合适的光载波上。因此,DSP部分的补偿是基于整体光信道进行补偿的。
然而,上述方案中的DSP补偿是基于一些已知的劣化(如色散、器件老化)进行补偿的,但实际上光器件引入的劣化往往大于预期,且伴随着一些难以分析的非线性效应,这使得补偿的效果不甚理想。通常,DSP的补偿可以削弱各种劣化带来的影响,却不能完全消除。因此,补偿后的光信道仍然呈现出不平坦的特性,数据在这样的光信道中进行传输不能达到最佳的匹配效果,降低了系统的整体性能。
因此,本申请提供一种调节光信道中流量分布的方法,可以调节数据流量在光信道中的分布,以达到充分匹配光信道的效果,从而提升系统的整体性能。
如图2所示,为本申请实施例提供的另一种系统框图。
参考图2,光信道中流量分布的调节主要通过成帧器模块、冗余填充模块和DSP处理模块完成。在实现上,可以将业务数据拆分为多个部分,经过不同的子DSP模块(如图中的TX_DSP0模块、TX_DSP1模块、TX_DSP2模块、……、TX_DSP(N-1)模块)处理后,调制到不同的频点(这些中心频点及其承载的信息可以称之为“tone”)上。相应地,对接收侧,将来自于数模转换器(analog to digital converter,ADC)的采样数据通过拆分模块拆分到各个子DSP模块上(如图中的RX_DSP0模块、RX_DSP1模块、RX_DSP2模块、……、RX_DSP(N-1)模块),并通过接收侧FEC处理得到业务数据。由于光信道并不平坦,不同频点上信息衰减存在差异。我们对不同tone承载的有效信息进行调节, 以此来获得整体上的最佳性能。
如图3所示,为本申请实施例提供的一种调节光信道中流量分布的方法300的示意图,该方法300可以包括步骤S310~S380。
S310,成帧器模块将第一帧业务数据所包括的N个业务数据分别配置在所述光信道的N个频点中,N为大于或等于2的整数;
本申请实施例中,成帧器模块可以先对第一帧业务数据进行拆分,将其拆分为N个业务数据,该N个业务数据中的每一个业务数据的数据大小可以相同,也可以不同,不予限制。
示例性地,假设第一帧业务数据的数据大小为500比特,且将该第一帧业务数据拆分为5个业务数据,则这5个业务数据的数据大小可以均为100比特,也可以分别依次为120比特、80比特、100比特、110比特、90比特。
本申请实施例中的N个频点及其承载的信息即为上文中提及的“tone”,在成帧器模块将第一帧业务数据拆分为N个业务数据后,可以将拆分后的N个业务数据配置在N个频点中。
如图4所示,为本申请实施例提供的一种光信道的信息分布的示意图。
参考图4中的(a),发送侧的信息作为一个整体,被均匀地分配到光信道上。参考图4中的(b),在不同频点上承载的有效信息量互不相同。
本申请实施例中的频点可以理解为某一频率范围的中心频点,如图4中的(b)所示出的,频点0为第一个频率范围(即图中第一个矩形在横坐标上的范围)的中心频点,频点1为第二个频率范围(即图中第二个矩形在横坐标上的范围)的中心频点等。
S320,第一数字信号处理DSP模块将M种数据流调制到所述光信道上,其中,所述M种数据流中每一种数据流包括所述N个业务数据和第一信息,所述第一信息包括所述成帧器模块对所述N个业务数据的数据流量分布进行调整的配置信息,M为大于或等于2的整数。
本申请实施例中,在成帧器模块将N个业务数据分别配置在所述光信道的N个频点中后,该成帧器模块可以将该N个业务数据的数据大小进行调整的数据流量分布的配置信息嵌入到数据流中,该配置信息可以包括M种。
本申请实施例中的M可以为大于或等于2的整数,如2、3、50、100等。
以下将以M=3为例说明本申请实施例中成帧器模块对N个业务数据的数据流量分布进行调整的配置信息。
第一种:
如图5所示,为本申请实施例提供的一种数据流量分布调整前后的信息分布示意图。其中,图5中的(a)为数据流量分布调整前的信息分布示意图,图5中的(b)为数据流量分布调整后的信息分布示意图。
结合图5中的(a)和(b),可以看出,成帧器模块减少频点0上的信息量,增加频点1上的信息量,且频点0上减少的信息量与频点1增加的信息量相等(如减少和增加10比特的信息量);同时,成帧器模块减少频点7上的信息量,增加频点6上的信息量,且频点7上减少的信息量与频点6增加的信息量相等(如减少和增加10比特的信息量)。
则该种方式下的配置信息可以为:减少频点0上的信息量,增加频点1上的信息量, 且频点0上减少的信息量与频点1增加的信息量相等(如减少和增加10比特的信息量);同时,减少频点7上的信息量,增加频点6上的信息量,且频点7上减少的信息量与频点6增加的信息量相等(如减少和增加10比特的信息量)。
第二种:
如图6所示,为本申请实施例提供的另一种数据流量分布调整前后的信息分布示意图。其中,图6中的(a)为数据流量分布调整前的信息分布示意图,图6中的(b)为数据流量分布调整后的信息分布示意图。
结合图6中的(a)和(b),可以看出,成帧器模块减少频点0上的信息量,增加频点2上的信息量,且频点0上减少的信息量与频点2增加的信息量相等(如频点0上减少50比特的信息量,频点2上增加10比特的信息量)。
则该种方式下的配置信息可以为:减少频点0上的信息量,增加频点2上的信息量,且频点0上减少的信息量与频点2增加的信息量相等(如减少和增加10比特的信息量)。
第三种:
如图7所示,为本申请实施例提供的又一种数据流量分布调整前后的信息分布示意图。其中,图7中的(a)为数据流量分布调整前的信息分布示意图,图7中的(b)为数据流量分布调整后的信息分布示意图。
结合图7中的(a)和(b),可以看出,成帧器模块减少频点1上的信息量,增加频点2上的信息量,且频点1上减少的信息量与频点2增加的信息量相等(如频点1上减少10比特的信息量,频点2上增加10比特的信息量);同时,成帧器模块减少频点6上的信息量,增加频点5上的信息量,且频点6上减少的信息量与频点7增加的信息量相等(如频点6上减少10比特的信息量,频点7上增加10比特的信息量)。
则该种方式下的配置信息可以为:减少频点1上的信息量,增加频点2上的信息量,且频点1上减少的信息量与频点2增加的信息量相等(如减少和增加10比特的信息量);同时,减少频点6上的信息量,增加频点5上的信息量,且频点6上减少的信息量与频点7增加的信息量相等(如减少和增加10比特的信息量)。
应理解,在实际过程中,成帧器模块对N个业务数据的数据流量分布进行调整的配置信息可能包括成百上千种,上述示例所示出的3种调整的配置信息仅为举例说明,不应对本申请造成特别限定。
还应理解,在M=3的情况下,上述实示例中所示出的3种调整的配置信息仅为示例性说明,还可能包括其它可能的调整的配置信息,如减少频点2的信息量,增加频点3的信息量等等,不应对本申请造成特别限定。
其中,本申请实施例中的第一信息可以基于如图8所示的帧格式嵌入数据流中,参考图8,可以看出,数据流量分布的配置信息可以认为是填充数据的一部分。
此外,本申请实施例中的第一DSP模块可以包括N个子DSP模块,该N个子DSP模块可以分别对N个业务数据进行处理。
需要说明的是,本申请实施例中的第一DSP模块将M种数据流调制到所述光信道上,可以理解为:第一DSP模块可以将第1种数据流调制到光信道上,该第1种数据流中包括成帧器模块对N个业务数据的数据流量分布进行调整的配置信息,示例性地,如上述第一种对N个业务数据的数据流量分布进行调整的配置信息;第一DSP模块可以将第2种 数据流调制到光信道上,该第2种数据流中包括成帧器模块对N个业务数据的数据流量分布进行调整的配置信息,示例性地,如上述第二种对N个业务数据的数据流量分布进行调整的配置信息;……;第一DSP模块可以将第M种数据流调制到光信道上。
还需要说明的是,本申请实施例中,在同一时刻,光信道上可以存在一种数据流的分布,因此,第一DSP模块将M种数据流调制到光信道的过程中,可以通过不同时刻将这M种数据流调制到光信道上。示例性地,第一DSP模块可以在第一时长范围(如0~5s)将第1种数据流调制到光信道上,在第二时长范围(如5~10s)将第2种数据流调制到光信道上,……,依次类推。
相应地,S330,第二DSP模块从所述光信道上获得M种数据流。
S340,解帧器模块从所述每一种数据流中提取所述第一信息,并根据所述第一信息对所述N个业务数据的数据流量分布进行调整。
本申请实施例中,第二DSP模块在从光信道上获得M种数据流后,可以从该M种数据流每一种数据流中提取第一信息,并根据第一信息对N个业务数据的数据流量分布进行调整,具体调整方式请参见下文。
本申请实施例中的调整可以理解为:解帧器模块在提取到第一信息后,可以根据该第一信息所包括的配置信息接收N个业务数据。
此外,还需要说明的是,在一些实施例中,第一DSP模块在将M种数据流(每一种数据流包括N个业务数据和第一信息)调制到光信道上后,成帧器模块也可以根据该第一信息所包括的配置信息调整N个业务数据。
S350,所述第二DSP模块根据调整后的N个业务数据确定M个SNR,所述M个SNR包括所述M种数据流中每一种数据流下所述光信道的SNR。
本申请实施例中的第二DSP模块在从光信道上获得M种数据流后,可以确定该M种数据流中每一种数据流下光信道的SNR。
本申请实施例中,M种数据流中每一种数据流下光信道的SNR可以理解为:每一种数据流下光信道整体的SNR,或者,也可以理解为每一种数据流下光信道所包括的N个tone的SNR。
可选地,在一些实施例中,所述第二DSP模块根据调整后的N个业务数据确定M个信噪比SNR,包括:
所述第二DSP模块根据调整后的N个业务数据的数据特性确定所述M个SNR。
本申请实施例中,第二DSP模块可以从每一种数据流中的N个业务数据的数据特性确定M个SNR,如可以通过测量业务数据的数据特性确定,不予限制。
S360,第二通信模块发送所述M个SNR至第一电子设备。
S370,第一通信模块接收M个SNR。
S380,所述成帧器模块根据所述M个SNR确定目标配置信息,并将第二帧业务数据按照所述目标配置信息配置在所述N个频点中,所述目标配置信息为所述M个SNR中SNR大于或等于第一阈值所对应的配置信息。
本申请实施例中,成帧器模块在接收到M个SNR后,可以将M个SNR中SNR大于第一阈值所对应的配置信息确定为目标配置信息,并按照该目标配置信息将第二帧业务数据配置在所述N个频点中。
仍然以M=3为例进行说明。
假设成帧器模块接收到的是表征光信道整体的SNR,如这3个SNR分别为70dB、110dB、90dB,若本申请实施例中的第一阈值为100,则目标配置信息可以为110dB所对应的配置信息;若本申请实施例中的第一阈值为90,则目标配置信息可以为110dB和90dB所对应的配置信息。
可选地,在一些实施例中,所述目标配置信息为所述M个SNR中SNR最大的所对应的配置信息。
如上述示例中所示出的,若本申请实施例中的第一阈值为90,则目标配置信息可以为110dB和90dB所对应的配置信息。在这种情况下,可以基于110dB所对应的配置信息对第二帧业务数据进行配置。
假设成帧器模块接收到的是表征光信道所包括的N个tone的SNR,此时该3个SRN可以认为是3组SNR,这3组SNR中每一组SNR均包括N个SNR。若N=8,示例性地,第1组SNR包括的8个SNR依次分别为:60dB、100dB、110dB、100dB、100dB、80dB、70dB、40dB;第2组SNR包括的8个SNR依次分别为:70dB、100dB、100dB、120dB、100dB、100dB、90dB、60dB;第3组SNR包括的8个SNR依次分别为:40dB、80dB、90dB、80dB、100dB、90dB、110dB、50dB。若本申请实施例中的第一阈值为90,可以看出,第2组中有6个频点的SNR大于或等于90,则目标配置信息可以为第2组所对应的配置信息。
本申请实施例提供的方案,第一DSP模块将M种数据流调制到光信道上,第二DSP模块从光信道上获得M种数据流后,确定M种数据流中每一种数据流下光信道的SNR,并将该M个SNR发送至第一电子设备,成帧器模块根据该M个SNR确定目标配置信息,并将第二帧业务数据按照目标配置信息配置在N个频点中。由于成帧器模块可以根据目标配置信息对第二帧业务数据进行配置,从而可以调节数据流量在光信道中的分布,以达到充分匹配光信道的效果,从而提升系统的整体性能。
上述步骤S380中指出,所述成帧器模块根据所述M个SNR确定目标配置信息,并将第二帧业务数据按照所述目标配置信息配置在所述N个频点中,具体地配置方式请参考下文。
可选地,在一些实施例中,所述将第二帧业务数据按照所述目标配置信息配置在所述N个频点中,包括:
所述成帧器模块将所述第二帧业务数据按照所述目标配置信息中频点所对应的数据流量分布配置在所述N个频点中。
本申请实施例中的第二帧业务数据可以是与第一帧业务数据在时域上相邻的数据。
成帧器模块在确定目标配置信息后,对于即将传输的第二帧业务数据,可以将其拆分为N个业务数据,其中,这N个业务数据中每一业务数据的数据大小可以基于目标配置信息进行拆分。
如上所述,假设成帧器模块接收到的表征光信道整体的3个SNR分别为70dB、110dB、90dB,则目标配置信息可以为110dB所对应的配置信息,或者,假设成帧器模块接收到的是表征光信道所包括的8个tone的SNR,则目标配置信息可以为第2组所对应的配置信息。即上述图6中的(b)所示出的信息分布,因此,对于即将传输的第二帧业务数据, 成帧器模块可以基于该信息分布对第二帧业务数据进行拆分,并将其配置在8个频点上。
从图6中的(b)可以看出,这8个频点上配置的数据的大小可以为:频点2=频点3=频点4>频点5>频点1=频点6=频点7>频点0。假设第二帧业务数据包括的数据大小为700比特,此时,可以按照上述大小关系对这1000比特的业务数据进行拆分,并将其配置在8个频点上。示例性地,可以在频点2、频点3以及频点4上配置100比特的数据,在频点5上配置90比特的数据,在频点1、频点6以及频点7上配置80比特的数据,在频点0上配置70比特的数据。
本申请实施例提供的方案,成帧器模块可以根据目标配置信息频点所对应的数据流量分布对第二帧业务数据进行配置,从而可以调节数据流量在光信道中的分布,以达到充分匹配光信道的效果,从而提升系统的整体性能。
可选地,在一些实施例中,在所述第一DSP模块将M种数据流调制到所述光信道上前,所述方法300还包括:
所述第一DSP模块根据所述第一信息对所述N个业务数据进行M种调整;
冗余填充模块对经过M种调整后的N个频点中的每一个频点填充冗余开销,以使得所述每一个频点输出的流量相等;
所述第一DSP模块将M种数据流调制到所述光信道上,包括:
所述第一DSP模块将填充所述冗余开销后的M种数据流调制到所述光信道上。
相应地,对于第二电子设备侧:
所述方法300还包括:
冗余剥离模块从所述每一种数据流所包括的N个频点中剥离出所述调整后的N个业务数据。
本申请实施例中,在成帧器模块将第一帧业务数据所包括的N个业务数据分别配置在光信道的N个频点中,并根据第一信息对N个业务数据进行M种调整后,可以先利用冗余填充模块填充N个频点中的每一个频点,以使得填充后的每一个频点输出的流量相等。由于成帧器模块对N个业务数据的数据大小进行不同方式的调整后,冗余填充模块对于不同方式的调整填充的冗余开销也不同。
上述图5-图7示出了成帧器模块对N个业务数据的数据流量分布进行3种方式的调整,其中,对于上述图5所示出的调整方式,即成帧器模块减少频点0上的信息量,增加频点1上的信息量,且频点0上减少的信息量与频点1增加的信息量相等;减少频点7上的信息量,增加频点6上的信息量,且频点7上减少的信息量与频点6增加的信息量相等。此时,为了保证每一个频点上输出的流量相等,可以利用冗余填充模块进行填充。
如图9所示,为本申请实施例提供的针对图5所示的数据流量分布调整前后填充冗余开销的信息分布示意图。其中,图9中的(a)为数据流量分布调整前填充冗余开销的信息分布示意图,图9中的(b)为数据流量分布调整后填充冗余开销的信息分布示意图。
结合图9中的(a)和(b),可以看出,数据流量分布调整前频点0和频点1上的有效信息的信息量相等(假设均为100比特),因此,冗余填充模块可以填充同等大小的冗余开销,如可以均填充28比特的冗余开销;而在数据流量分布调整后频点0上的有效信息小于频点1上的有效信息(假设此时频点0上的有效信息为90比特,频点1上的有效信息为110比特),因此,冗余填充模块可以填充不同大小的冗余开销,具体地,频点0 上填充的冗余开销小于频点1上填充的冗余开销,如频点0上填充38比特的冗余开销,频点1上填充18比特的冗余开销。类似地,对于频点6和频点7也可以进行相应地冗余开销的填充。
对于上述图6所示出的调整方式,即成帧器模块减少频点0上的信息量,增加频点2上的信息量,且频点0上减少的信息量与频点2增加的信息量相等。此时,为了保证每一个频点上输出的流量相等,可以利用冗余填充模块进行填充。
如图10所示,为本申请实施例提供的针对图6所示的数据流量分布调整前后填充冗余开销的信息分布示意图。其中,图10中的(a)为数据流量分布调整前填充冗余开销的信息分布示意图,图10中的(b)为数据流量分布调整后填充冗余开销的信息分布示意图。
结合图10中的(a)和(b),可以看出,数据流量分布调整前频点0上的有效信息的信息量小于频点2上的有效信息的信息量(假设此时频点0上的有效信息为100比特,频点2上的有效信息为110比特),因此,冗余填充模块可以填充不同大小的冗余开销,具体地,频点0上填充的冗余开销大于频点2上填充的冗余开销,如频点0上填充28比特的冗余开销,频点2上填充18比特的冗余开销;而在数据流量分布调整后频点0上的有效信息减少,频点2上的有效信息增加(假设此时频点0上的有效信息为90比特,频点2上的有效信息为120比特),因此,相比于数据流量分布调整前,冗余填充模块在频点0上填充的冗余开销增加,在频点2上填充的冗余开销减少,如频点0上填充38比特的冗余开销,频点2上填充8比特的冗余开销。
对于上述图7所示出的调整方式,即成帧器模块减少频点1上的信息量,增加频点2上的信息量,且频点1上减少的信息量与频点2增加的信息量相等;同时,成帧器模块减少频点6上的信息量,增加频点5上的信息量,且频点6上减少的信息量与频点7增加的信息量相等。此时,为了保证每一个频点上输出的流量相等,可以利用冗余填充模块进行填充。
如图11所示,为本申请实施例提供的针对图7所示的数据流量分布调整前后填充冗余开销的信息分布示意图。其中,图11中的(a)为数据流量分布调整前填充冗余开销的信息分布示意图,图11中的(b)为数据流量分布调整后填充冗余开销的信息分布示意图。
结合图11中的(a)和(b),可以看出,数据流量分布调整前频点1上的有效信息的信息量小于频点2上的有效信息的信息量(假设此时频点1上的有效信息为100比特,频点2上的有效信息为110比特),因此,冗余填充模块可以填充不同大小的冗余开销,具体地,频点1上填充的冗余开销大于频点2上填充的冗余开销,如频点0上填充28比特的冗余开销,频点2上填充18比特的冗余开销;而在数据流量分布调整后频点1上的有效信息减少,频点2上的有效信息增加(假设此时频点1上的有效信息为90比特,频点2上的有效信息为120比特),因此,相比于数据流量分布调整前,冗余填充模块在频点1上填充的冗余开销增加,在频点2上填充的冗余开销减少,如频点1上填充38比特的冗余开销,频点2上填充8比特的冗余开销。类似地,对于频点5和频点6也可以进行相应地冗余开销的填充。
需要说明的是,上述各实施例中,冗余填充模块所填充的冗余开销使得每一个频点输出的流量相等均为128比特,在一些实施例中,冗余填充模块所填充的冗余开销可以使得每一个频点输出的流量相等均为256比特等,不予限制。
本申请实施例提供的方案,在成帧器模块对N个业务数据的数据大小进行调整后,可以先利用冗余填充模块填充N个频点中的每一个频点,以保证填充后的每一个频点输出的流量相等,可以使得后续在对数据进行处理的过程中对流量分布变化的不感知,保证流量调整前后的连续性,从而实现对用户无感知的灵活无损切换。
可选地,在一些实施例中,所述N个业务数据中的第i个业务数据包括F i比特的数据量,且

所述第一DSP模块将M种数据流调制到所述光信道上,包括:
所述第一DSP模块将转换后的M种数据流调制到所述光信道上。
本申请实施例中,在第一DSP模块将M种数据流调制到所述光信道上前,可以先对成帧器模块输出的N个业务数据的数据大小进行格式转换,此处的格式转换可以理解为对N个频点中的第i个频点所包括的时钟周期(也可以称为“拍”)进行转换。
如上所述,成帧器模块可以将第一帧业务数据所包括的N个业务数据分别配置在所述光信道的N个频点中,每一个频点上的数据量可能不同,即不同频点所包括的时钟上的有效数据量不同。所以成帧器模块需要对每个频点上分配的数据量进行调整。不失一般性,我们以一个FEC帧为单位来描述数据量分配的过程(即格式转换)。
如图12所示,为本申请实施例提供的一种数据格式转换的示意图。其中,图12中的(a)为数据格式转换前的示意图,图12中的(b)、图12中的(c)、图12中的(d)分别为数据格式转换后的示意图。
参考图12中的(a),可以看到,在一个FEC帧中,原始的业务数据有8个时钟周期,每个时钟周期包括Q比特有效数据,总共的数据量就有8*Q比特,在某一种数据流量分配方式中,每个频点上需要分配的有效数据量分别为T i比特(i=1、2、3…N),此时就需要通过成帧器模块来将8*Q比特数据按照需要分配到每个频点上,假设分配后的数据有6个时钟周期,那么分配时保证8*Q=6*(T 1+T 2+……+T N)。上述的8、6、Q、T i均是基于系统的设计参数,这里不再展开描述。
此外,为了匹配后续模块,冗余填充模块可以填充K i比特的无效数据。
示例性地,在数据格式转换前,这8个时钟周期中每一个时钟周期包括90比特的有效数据;对于图12中的(b),在数据格式转换后,频点0包括6个时钟周期,每一个时钟周期包括120比特的有效数据,同时为了匹配后续模块,可以插入一定数量的无效数据,如可以插入8比特的无效数据。
对于图12中的(c),在数据格式转换后,频点1包括6个时钟周期,每一个时钟周期包括122比特的有效数据,同时为了匹配后续模块,可以插入一定数量的无效数据,如可以插入6比特的无效数据。
以此类推……
对于图12中的(d),在数据格式转换后,频点7包括6个时钟周期,每一个时钟周期包括116比特的有效数据,同时为了匹配后续模块,可以插入一定数量的无效数据,如可以插入12比特的无效数据。
参考上述图12,可以看出,成帧器模块将原始业务数据分配为6个时钟周期,且每 一个频点所包括的时钟周期的有效数据的数据量可能不同,可以对频点所包括的时钟周期进行无效数据的插入,如图12中的(b)中在频点0所包括的6个时钟周期插入8比特的无效数据,或者,图12中的(c)中在频点1所包括的6个时钟周期插入6比特的无效数据,或者,图12中的(d)中在频点7所包括的6个时钟周期插入12比特的无效数据。
本申请实施例提供的方案,在成帧器模块对N个业务数据的数据流量分布进行调整前,成帧器模块可以先将R*Q比特的数据量转换为
Figure PCTCN2021143788-appb-000008
比特的数据量,同时,冗余填充模块可以对每一个时钟周期上的数据进行无效填充,使得填充后的每一个时钟周期上的数据量相等,以匹配后续模块所需要的数据格式。
可选地,在一些实施例中,所述成帧器模块将所述R*Q比特的数据量转换为
Figure PCTCN2021143788-appb-000009
比特的数据量,包括:
所述成帧器模块根据数模转换器的采样率将所述R*Q比特的数据量转换为
Figure PCTCN2021143788-appb-000010
比特的数据量。
本申请实施例中,成帧器模块在进行数据格式转换时,可以根据数模转换器的采样率进行转换。如后续数模转换器的采样率为64GHz,在系统设计中,折算至每路冗余填充模块输出的数据流量为64*F Gbps(F是系统设计中的一个固有值),假设系统的时钟频率为500MHz,此时每路冗余填充模块的输出数据量即为64*F/0.5=128*F比特。为不失一般性,假设F=1,此时每路冗余填充模块的输出数据量为128比特,此时就需要利用成帧器模块和冗余填充模块来将原始的业务数据转换为每个时钟周期输出128比特的数据量(有效数据+冗余填充数据)。
如上述图12中的(b)、图12中的(c)以及图12中的(d)所示出的,每一个时钟周期均包括128比特的数据,区别在于有效数据的数据量和无效数据的数据量的不同。
上述步骤S340中指出,解帧器模块从所述每一种数据流中提取所述第一信息,并根据所述第一信息对所述N个业务数据的数据流量分布进行调整。具体调整方式请参考下文。
本申请实施例中,若第二DSP模块从光信道上获得3种数据流,且每一种数据流上包括成帧器模块对N个业务数据的数据流量分布进行调整的配置信息。解帧器模块可以分别从这3种数据流上提取对N个业务数据的数据流量分布进行调整的配置信息,并根据所提取的配置信息进行相应的调整。
示例性地,如上述图5-图7示出了成帧器模块对N个业务数据的数据流量分布进行3种方式的调整,则第二DSP模块从光信道上获得3种数据流,成帧器模块可以从分别这3种数据流上提取对N个业务数据的数据流量分布进行调整的配置信息。
如上述图5所示出的调整方式,即成帧器模块减少频点0上的信息量,增加频点1上的信息量,且频点0上减少的信息量与频点1增加的信息量相等;减少频点7上的信息量,增加频点6上的信息量,且频点7上减少的信息量与频点6增加的信息量相等。则第二DSP模块在获得相应的数据流后,解帧器模块可以从该数据流中提取该调整方式所对应的配置信息,并根据该配置信息对N个业务数据进行相应的调整。
假设图5中的(a)中,频点0~频点7上的有效信息的大小分别依次为100比特、100比特、110比特、120比特、120比特、110比特、100比特、100比特,则接收侧的解帧器模块在提取到该调整方式下的配置信息(该配置信息可以为减少频点0上的信息量,增 加频点1上的信息量,且频点0上减少的信息量与频点1增加的信息量相等(如减少和增加10比特的信息量);同时,成帧器模块减少频点7上的信息量,增加频点6上的信息量,且频点7上减少的信息量与频点6增加的信息量相等(如减少和增加10比特的信息量))后,可以在所对应的频点上进行相应的调整,即将频点0~频点7上的数据大小分别依次调整为90比特、110比特、110比特、120比特、120比特、110比特、110比特、90比特。
如上述图6所示出的调整方式,即成帧器模块减少频点0上的信息量,增加频点2上的信息量,且频点0上减少的信息量与频点2增加的信息量相等。则第二DSP模块在获得相应的数据流后,解帧器模块可以从该数据流中提取该调整方式所对应的配置信息,并根据该配置信息对N个业务数据进行相应的调整。
类似地,假设图6中的(a)中,频点0~频点7上的有效信息的大小分别依次为100比特、100比特、110比特、120比特、120比特、110比特、100比特、100比特,则接收侧的解帧器模块在提取到该调整方式下的配置信息(该配置信息可以为减少频点0上的信息量,增加频点2上的信息量,且频点0上减少的信息量与频点2增加的信息量相等(如减少和增加10比特的信息量))后,可以在所对应的频点上进行相应的调整,即将频点0~频点7上的数据大小分别依次调整为90比特、100比特、120比特、120比特、120比特、110比特、100比特、100比特。
如上述图7所示出的调整方式,即成帧器模块减少频点1上的信息量,增加频点2上的信息量,且频点1上减少的信息量与频点2增加的信息量相等;同时,成帧器模块减少频点6上的信息量,增加频点5上的信息量,且频点6上减少的信息量与频点7增加的信息量相等。则第二DSP模块在获得相应的数据流后,解帧器模块可以从该数据流中提取该调整方式所对应的配置信息,并根据该配置信息对N个业务数据进行相应的调整。
类似地,假设图7中的(a)中,频点0~频点7上的有效信息的大小分别依次为100比特、100比特、110比特、120比特、120比特、110比特、100比特、100比特,则接收侧的解帧器模块在提取到该调整方式下的配置信息(该配置信息可以为减少频点1上的信息量,增加频点2上的信息量,且频点1上减少的信息量与频点2增加的信息量相等(如减少和增加10比特的信息量);同时,成帧器模块减少频点6上的信息量,增加频点5上的信息量,且频点6上减少的信息量与频点7增加的信息量相等(如减少和增加10比特的信息量))后,可以在所对应的频点上进行相应的调整,即将频点0~频点7上的数据大小分别依次调整为100比特、90比特、120比特、120比特、120比特、120比特、90比特、100比特。
本申请实施例提供的方案,在第二DSP模块从光信道上获得M种数据流,解帧器模块从每一种数据流中提取第一信息(该第一信息包括成帧器模块对所述N个业务数据的数据流量分布进行调整的配置信息),并根据该第一信息进行相应的调整,同时基于调整后的数据流量分布确定M个SNR,以便于成帧器模块根据该M个SNR确定用于配置第二帧业务数据的目标配置信息,以充分匹配光信道,从而提升系统的整体性能。
上述步骤S340中指出,解帧器模块从每一种数据流中提取第一信息,在一些实施例中,可以在确定提取的第一信息无误的情况下,对N个业务数据的数据流量分布进行调整。
可选地,在一些实施例中,所述解帧器模块从所述每一种数据流中提取所述第一信息, 包括:
所述解帧器模块多次从所述每一种数据流中提取所述第一信息;
所述方法还包括:
当所述解帧器模块多次从所述每一种数据流提取的所述第一信息相同时,确认所述第一信息正确;
所述根据所述第一信息对所述N个业务数据的数据流量分布进行调整,包括:
在确认所述第一信息正确的情况下,所述解帧器模块根据所述第一信息对所述N个业务数据的数据流量分布进行调整。
本申请实施例中,解帧器模块多次从每一种数据流中提取所述第一信息,并在确认第一信息正确的情况下,根据第一信息进行相应的配置。
以上述图5中的(b)为例,解帧器模块可以多次从相应的数据流中提取第一信息,假设解帧器模块提取了10次,且这10次提取的第一信息均相同,则接收侧可以根据第一信息对N个业务数据的数据流量分布进行调整。
类似地,对于上述图6中的(b)、图7中的(b)所示的调整方式,解帧器模块均可以多次从相应的数据流中提取第一信息,并在确认第一信息正确的情况下,根据第一信息对N个业务数据的数据流量分布进行调整。
本申请实施例提供的方案,解帧器模块可以多次从每一种数据流中提取所述第一信息,并在确认第一信息正确的情况下,根据第一信息对N个业务数据的数据流量分布进行调整,可以进一步提升系统的性能。
