一种数据交织方法及数据交织装置
本申请要求于2021年09月03日提交中国专利局、申请号为202111034610.X、发明名称为“一种数据交织方法及数据交织装置”的中国专利申请的优先权和于2022年03月23日提交中国专利局、申请号为202210290884.3、发明名称为“一种数据交织方法及数据交织装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,尤其涉及一种数据交织方法及数据交织装置。
背景技术
在5G、云计算、大数据和人工智能等持续推动下,光通信系统及光传输网(optical transport network,OTN)正朝着大容量和超高速方向发展。采用前向纠错编码(forward error correction,FEC)对传输的数据进行纠错,能够解决传输误码,从接收数据中恢复出发送端发送的原始数据。
当前提出有一种级联FEC的传输方案,发端设备和发端处理模块通过连接单元接口(attachment unit interface,AUI)连接。发端设备对待传输数据进行第一FEC编码,并将第一FEC编码后的数据发送至发端处理模块。发端处理模块对第一FEC编码后的数据再进行第二FEC编码,并将第二FEC编码后的数据通过信道传输至数据接收端。具体地,发端处理模块会收到多路数据流,要分别先对多路数据流先进行卷积交织,再对卷积交织后的每一路数据流进行第二FEC编码。应理解,为了提升性能应当使得参与第二FEC编码的一路数据流来自于第一FEC编码后的多个码字,不过这需要采用时延较长的卷积交织来实现,在要求低时延的场景下应用效果不理想。
发明内容
本申请实施例提供了一种数据交织方法及数据交织装置。可以在采用较低时延的场景下获得较好的级联FEC方案性能。
第一方面,本申请提供了一种数据交织方法,该方法包括如下步骤。根据n条延迟线分别对n路数据流进行延迟,n为能被p整除的正整数,p为大于1的整数。每条延迟线的延迟取值为延迟取值集合中的任一种延迟取值,延迟取值集合包括p个延迟取值,延迟取值集合中最小的延迟取值为0,且延迟取值集合的p个延迟取值按从小到大的顺序每相邻两个延迟取值的差值为V个符号,V为大于或等于34的整数,延迟取值集合中每个延迟取值对应的延迟线的数量为n/p。之后,从延迟后的n路数据流各获取L×m个符号以得到L个第一符号集合,每个第一符号集合包括n×m个符号,L为大于或等于1的整数,m为大于或等于1的整数。进而,对L个第一符号集合分别进行交织得到L个第二符号集合,每个第二符号集合中的符号数量与每个第一符号集合中的符号数量相同。
在该实施方式中,n路数据流都为经过外码编码后的码字,在对n路数据流分别进行延 迟之后,还将对延迟后的n路数据流进行数据交织。采用本申请提供的延迟处理方案,通过较短的时延就能实现延迟后的n路数据流在同一时刻输出的n个符号来自多个不同的外码码字,在保证较好性能的基础上也有助于降低数据交织的时延。也就是说,本申请中延迟处理与数据交织相结合的方案所采用的整体时延较低,更适用于要求低时延的应用场景。
在一些可能的实施方式中,p=4,n能被16整除,n条延迟线包括至少一组延迟线,每一组延迟线包括16条相邻的延迟线,n条延迟线的第k组延迟线中第a 0条延迟线、第a 1条延迟线、第a 2条延迟线、第a 3条延迟线、第a 4条延迟线、第a 5条延迟线、第a 6条延迟线、第a 7条延迟线、第a 8条延迟线、第a 9条延迟线、第a 10条延迟线、第a 11条延迟线、第a 12条延迟线、第a 13条延迟线、第a 14条延迟线和第a 15条延迟线的延迟取值满足第一条件,其中,0≤k<n/16,a 0、a 1、a 2、a 3、a 4、a 5、a 6、a 7、a 8、a 9、a 10、a 11、a 12、a 13、a 14、a 15为小于16的非负整数且互不相等,第一条件为:

在该实施方式中,对于客户侧为每个通道100Gb/s的8×100G接口且采用“100G RS-FEC”模式。若满足上述第一条件且V≥68时,32条数据流中的数据流0-15(或数据流16-31)经过延迟处理后每一次分别输出的16个符号中第a 0个符号和第a 1个符号来自2个不同的RS码字符号,第a 2个符号和第a 3个符号来自2个不同的RS码字符号,…,第a 14个符号和第a 15个符号来自2个不同的RS码字符号,通过这种延迟设计方式便于后面采用实现简单且时延较低的交织处理方案以实现较好的级联FEC方案性能,减少整体传输方案时延。

具体实施方式
本申请实施例提供了一种数据交织方法及数据交织装置。需要说明的是,本申请说明书和权利要求书及上述附图中的术语“第一”、“第二”等用于区别类似的对象,而非限定特定的顺序或先后次序。应该理解,上述术语在适当情况下可以互换,以便在本申请描述的实施例能够以除了在本申请描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含。例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
图1为本申请实施例应用的一种通信系统示意图。如图1所示,该通信系统包括发端设备01、发端处理模块02、信道传输媒介03、收端处理模块04和收端设备05。以该通信系统是数据中心网络为例,发端设备01和收端设备05可以为交换机或路由器等设备,且发端设备01也称为位于发端的客户侧芯片(host chip),收端设备05也称为位于收端的客户侧芯片,信道传输媒介03可以为光纤。其中,发端设备01与发端处理模块02之间可以通过连接单元接口(attachment unit interface,AUI)连接,收端设备05与收端处理模块04之间可以通过AUI连接。发端处理模块02和收端处理模块04可以为光模块(optical module)、电模块或其他在数据发送过程中对数据进行处理的模块。例如,该处理模块可以为800LR模块(800LR module,一种相干光模块)。并且,该通信系统中的发端设备01、发端处理模块02、信道传输媒介03、收端处理模块04和收端设备05均可以支持双向传输,也可以支持单向传输,具体此处不做限定。
图2为图1所示通信系统中一种数据传输的过程示意图。如图2所示,在从发端设备01向收端设备05传输数据的过程中,发端设备01用于对该数据进行外码编码,然后向发端处理模块02传输经过外码编码的数据。发端处理模块02用于对经过外码编码的数据进行内码编码,得到经过外码编码和内码编码的数据,并将经过外码编码和内码编码的数据传输至信道传输媒介03。信道传输媒介03用于将经过外码编码和内码编码的数据传输至收端处理模 块04。收端处理模块04用于对经过外码编码和内码编码的数据进行内码译码,并向收端设备05传输经过内码译码的数据。收端设备05用于对经过内码译码的数据进行外码译码。
应理解,内码中的“内”和外码中的“外”只是基于对数据进行操作的执行主体相对于信道传输媒介03的距离的远近来区分的。对内码进行操作的执行主体较靠近信道传输媒介,对外码进行操作的执行主体较远离信道传输媒介。在本申请实施例中,由于数据从发端设备01发出后经过发端处理模块02传输至信道传输媒介03,然后从信道传输媒介03经过收端处理模块04传输至收端设备05。经发端设备01编码的数据相对于经发端处理模块02编码的数据离信道传输媒介03较远,经收端设备05译码的数据相对于经收端处理模块04译码的数据离信道传输媒介03较远。因此经发端设备01编码的数据称为经过外码编码的数据,经发端处理模块02编码的数据称为经过内码编码的数据,经收端设备05译码的数据称为经过外码译码的数据,经收端处理模块04译码的数据称为经过内码译码的数据。在一种可能的实施方式中,上述的内码编码和外码编码都是采用FEC编码的方式,从而形成一种级联FEC的传输方案。例如,发端设备01可以采用RS码进行外码编码,发端处理模块02可以采用汉明(Hamming)码进行内码编码。
需要说明的是,以上内容是对本申请实施例提供的数据交织方法的应用场景的示例性说明,并不构成对于数据交织方法的应用场景的限定,本领域普通技术人员可知,随着业务需求的改变,其应用场景可以根据应用需求进行调整,本申请实施例对其不做一一列举。
对于上述采用级联FEC的传输方案,本申请设计一种包含“延迟”和“交织”的数据交织方案,以实现整体级联FEC方案性能较好且时延较低。使得该级联FEC传输方案能够应用于较多的传输场景,尤其适用于对需要较低传输时延的传输场景,如低时延数据中心互联场景。其中,数据交织是通过上述的发端处理模块02来实现的。
图3(a)为本申请实施例中发端处理模块的数据处理示意图。如图3(a)所示,发端处理模块的物理媒体附加子层(Physical Medium Attachment,PMA)子层对来自多个同步的客户通道(client lane)的数据进行解复用(de-muxing)处理后,可以得到n条经过外码编码的物理编码子层(Physical Coding Sublayer,PCS)或FEC通道数据流,并进行标识锁定(alignment lock)和通道纠偏处理(lane de-skew)得到对齐的n条通道数据流。然后根据对齐标识对n条通道的数据进行通道重排序(lane reorder)处理,使得n条通道的数据能够按照指定的顺序排列。经通道重排序的n条通道数据流送入所设计的延迟和交织处理器进行交织打乱数据顺序处理后送入内码编码器进行内码编码。经过内码编码的数据流进行数据处理后送入信道传输媒介进行传输。该数据处理可包括调制映射(mapping),信道交织(channel interleaving),偏振划分(polarization distribution)或DSP成帧处理(framing)等。其中,这里n为大于1的正整数。
图3(b)为本申请实施例中发端处理模块的另一种数据处理示意图。如图3(b)所示,来自PMA子层的n条PCS或FEC通道数据流,经过标识锁定和通道纠偏处理得到对齐的n条通道数据流。n条通道数据流直接送入所设计的延迟和交织处理器进行交织打乱数据顺序处理后送入内码编码器进行内码编码。
在一些实际场景中,通道纠偏处理模块利用先进先出(First input first output,FIFO)进行缓存数据。考虑所设计的延迟处理中的延迟线采用存储单元实现,为了降低硬件实现复 杂度和功耗,可将通道纠偏处理和延迟处理合并一起实现,采用一套FIFO同时实现纠偏处理和延迟处理。
图3(c)为本申请实施例中发端处理模块的又一种数据处理示意图。如图3(c)所示,来自PMA子层的n条PCS或FEC通道数据流,先进行标识锁定,并根据通道对齐标识进行通道纠偏处理和所设计的延迟处理,然后根据通道对齐标识进行通道重排序,再进行所设计的交织处理,经过交织打乱顺序的数据送入内码编码器进行内码编码。
图3(d)为本申请实施例中发端处理模块的再一种数据处理示意图。如图3(d)所示,来自PMA子层的n条PCS或FEC通道数据流,先进行标识锁定,并根据通道对齐标识进行通道纠偏处理和所设计的延迟处理,再进行所设计的交织处理,经过交织打乱顺序的数据送入内码编码器进行内码编码。
图4(a)为本申请实施例中针对收端处理模块的数据处理示意图。如图4(a)所示,收端处理模块接收来自信道传输媒介的数据流。当发端处理模块数据流是经过调制映射(mapping),信道交织(channel interleaving),偏振划分(polarization distribution)或DSP成帧处理(framing)等数据处理时,收端处理模块先进行相应的数据逆处理后再送入内码译码器进行译码。内码译码后数据流送入解交织和逆延迟处理器处理后得到n条通道数据流,再送入PMA子层。PMA子层将数据流进行复用处理后送入收端设备进行外码译码。这里收端处理模块中解交织和逆延迟处理是发端处理模块中延迟和交织处理的逆操作。其中解交织是发端处理模块中交织的逆操作,逆延迟是发端处理模块中交织的逆操作。
图4(b)为本申请实施例中针对收端处理模块的另一种数据处理示意图。如图4(b)所示,收端处理模块接收来自信道传输媒介的数据流。内码译码后的数据流进行解交织处理后得到n条通道数据流,并送入PMA子层。这里收端处理模块中解交织处理是发端处理模块中交织处理的逆操作。应理解,图4(b)所示的数据处理流程中,内码译码后的数据流进行解交织处理后的n条通道数据流并没有进行逆延迟处理,而是直接送入PMA子层。也就是,送入PMA子层的n条通道数据流并不是对齐的,通道数据流之间存在延迟。PMA子层将n条通道数据流进行复用处理后送入收端设备。和图4(a)所示的数据处理相比,图4(b)所示的数据处理具有较低的功耗和较低的硬件实现复杂度。
下面对发端处理模块中的延迟和交织处理进行详细描述。收端处理模块的解交织和逆延迟处理是发端处理模块中延迟和交织处理的逆操作,本领域普通技术人员可知,此处不再赘述。
下面首先提供几种本申请实施例可应用的几种具体场景。
图5为发端设备采用1×800G接口的32条PCS通道数据流的示意图。如图5所示,发端设备将待传输的1路800GE业务数据流进行KP4RS(544,514)码外码编码得到32条PCS通道(PCS lane)数据流。PCS通道数据流0-15中每条数据流间隔68个符号总共16*68=1088个符号,其包含了2个RS码码字。每条PCS通道数据流中相邻2个符号来自不同RS码码字,且相邻两条PCS通道数据流的同个位置的2个符号来自不同RS码码字。类似的,PCS通道数据流16-31中每条数据流间隔68个符号总共16*68=1088个符号,其包含了2个RS码码字。每条PCS通道数据流中相邻2个符号来自不同RS码码字,且相邻两条PCS通道数据流的同个 位置的2个符号来自不同RS码码字。32条PCS通道数据流经PMA处理后通过连接单元接口800GAUI-8送入发端处理模块。
基于上述图3(a)-图3(d)所示的发端处理模块的数据处理示意图,发端处理模块利用PCS通道已知的对齐标识(Alignment marker)进行通道数据流的标识锁定(alignment lock)。这里32个通道的已知对齐标识各不相同(见《Ethernet Technology Consortium 800G Specification》)。发端处理模块接着对32个通道数据流进行通道纠偏处理(lane de-skew)得到对齐的32条通道数据流。然后根据对齐标识对n=32条通道的数据进行通道重排序(lane reorder)处理,使得n=32条通道的数据能够按照指定的顺序排列。一种顺序是跟图5一样通道数据流从上往下按从0到31排序。
图6为发端设备采用2×400G接口的32条PCS通道数据流的示意图。如图6所示,发端设备将待传输的2路400GE业务数据流进行KP4RS(544,514)码外码编码得到2路总共32条PCS通道数据流,其中每路包括16条PCS通道数据流。PCS通道数据流0-15或PCS通道数据流16-31中每条数据流间隔68个符号总共16*68=1088个符号,其包含了2个RS码码字。每条PCS通道数据流中相邻2个符号来自不同RS码码字,且相邻两条PCS通道数据流的同个位置的2个符号来自不同RS码码字。32条PCS通道数据流经PMA处理后通过连接单元接口2×400GAUI-4送入发端处理模块。
基于上述图3(a)-图3(d)所示的发端处理模块的数据处理示意图,发端处理模块利用PCS通道0-15或PCS通道16-31已知的对齐标识(Alignment marker)进行16个通道数据流的标识锁定(alignment lock)。这里PCS通道0-15可认为是第0路400G中的PCS通道0-15,PCS通道16-31可认为是第1路400G中的PCS通道0-15。第0路400G中的16个通道已知的对齐标识和第1路中的16个通道已知的对齐标识相同。发端处理模块接着对32个通道数据流进行通道纠偏处理(lane de-skew)得到对齐的32条通道数据流。然后根据PCS通道0-15或PCS通道16-31的对齐标识对16条通道的数据进行通道重排序(lane reorder)处理,使得16条通道的数据能够按照指定的顺序排列。最后使得32条通道的数据能够按照指定的顺序排列。一种顺序是跟图6一样通道数据流从上往下按从0到31排序。
应理解,上述发端处理模块对32个通道数据流进行通道纠偏处理得到对齐的32条通道数据流,一种具体实现方式是根据PCS通道0-15或PCS通道16-31已知的对齐标识对16条通道的数据进行现有标准定义的通道纠偏处理(见IEEE 802.3Clause 120),使得第0路或第1路400G中的PCS通道数据流不存在偏差,也即不存在时延。同时利用对齐标识使得两路PCS通道数据流是符号对齐的。此时第0路中的PCS通道数据流和第1路中的PCS通道数据流可以是不存在偏差,也可以是存在偏差。考虑RS符号包含10个比特,对齐后的PCS通道数据流中,第0路中的PCS通道数据流和第1路中的PCS通道数据流存在偏差的比特数目是10的倍数。
图7为发端设备采用4×200G接口的32条PCS通道数据流的示意图。如图7所示,发端设备将待传输的4路200GE业务数据流进行KP4RS(544,514)码外码编码得到4路总共32条PCS通道数据流,其中每路包括8条PCS通道数据流。PCS通道数据流0-7、PCS通道数据流8-15、PCS通道数据流16-23或PCS通道数据流24-31中每条数据流间隔136个符号总共8*136=1088个符号,其包含了2个RS码码字。每条PCS通道数据流中相邻2个符号来自不 同RS码码字,且相邻两条PCS通道数据流的同个位置的2个符号来自不同RS码码字。32条PCS通道数据流经PMA处理后通过连接单元接口4×200GAUI-2送入发端处理模块。
基于上述图3(a)-图3(d)所示的发端处理模块的数据处理示意图,发端处理模块利用PCS通道0-7、PCS通道8-15、PCS通道16-23或PCS通道24-31已知的对齐标识(Alignment marker)进行8个通道数据流的标识锁定(alignment lock)。这里PCS通道0-7、PCS通道8-15、PCS通道16-23或PCS通道24-31可分别认为是第0路、第1路、第2路或第3路200G中的PCS通道0-7。发端处理模块接着对32个通道数据流进行通道纠偏处理(lane de-skew)得到对齐的32条通道数据流。然后根据PCS通道0-7、PCS通道8-15、PCS通道16-23或PCS通道24-31的对齐标识对8条通道的数据进行通道重排序(lane reorder)处理,使得8条通道的数据能够按照指定的顺序排列。最后使得32条通道的数据能够按照指定的顺序排列。一种顺序是跟图7一样通道数据流从上往下按从0到31排序。
应理解,上述发端处理模块对32个通道数据流进行通道纠偏处理得到对齐的32条通道数据流,一种具体实现方式是根据PCS通道0-7、PCS通道8-15、PCS通道16-23或PCS通道24-31已知的对齐标识对8条通道的数据进行现有标准定义的通道纠偏处理(见IEEE802.3Clause 120),使得第0路、第1路、第2路或第3路200G中的PCS通道数据流不存在偏差,也即不存在时延。同时利用对齐标识使得四路PCS通道数据流是符号对齐的。此时第0路、第1路、第2路和第3路之间的PCS通道数据流可以是不存在偏差,也可以是存在偏差。考虑RS符号包含10个比特,对齐后的PCS通道数据流中,第0路、第1路、第2路和第3路之间的PCS通道数据流存在偏差的比特数目是10的倍数。
图8为发端设备采用8×100G接口的32条PCS通道数据流的一种示意图。如图8所示,发端设备将待传输8路100GE业务数据流进行KP4RS(544,514)码外码编码得到8路总共32条FEC通道(FEC lane)数据流,其中每路包括4条FEC通道数据流。当采用2个KP4RS(544,514)码字交织的“100G RS-FEC-Int”模式时,FEC通道数据流0-3、FEC通道数据流4-7、FEC通道数据流8-11、FEC通道数据流12-15、FEC通道数据流16-19、FEC通道数据流20-23、FEC通道数据流24-27或FEC通道数据流28-31中每条数据流间隔272个符号总共4*272=1088个符号,其包含了2个RS码码字。每条FEC通道数据流中相邻2个符号来自不同RS码码字,且相邻两条FEC通道数据流的同个位置的2个符号来自不同RS码码字。32条FEC通道数据流经PMA处理后通过连接单元接口8×100GAUI-1送入发端处理模块。
图9为发端设备采用8×100G接口的32条PCS通道数据流的另一种示意图。如图9所示,区别于上述图8的场景,本场景中发端设备采用“100G RS-FEC”模式,FEC通道数据流0-3、FEC通道数据流4-7、FEC通道数据流8-11、FEC通道数据流12-15、FEC通道数据流16-19、FEC通道数据流20-23、FEC通道数据流24-27或FEC通道数据流28-31中每条数据流间隔136个符号总共4*136=544个符号,其包含了1个RS码码字。32条FEC通道数据流经PMA处理后通过连接单元接口8×100GAUI-1送入发端处理模块。
基于上述图3(a)-图3(d)所示的发端处理模块的数据处理示意图,发端处理模块利用FEC通道0-3、FEC通道4-7、FEC通道8-11、FEC通道12-15、FEC通道16-19、FEC通道20-23、FEC通道24-27或FEC通道28-31已知的对齐标识(Alignment marker)进行4个通道数据流的标识锁定(alignment lock)。这里FEC通道0-3、FEC通道4-7、FEC通道8-11、 FEC通道12-15、FEC通道16-19、FEC通道20-23、FEC通道24-27或FEC通道28-31可分别认为是第0路、第1路、第2路、第3路、第4路、第5路、第6路或第7路100G中的FEC通道0-3。发端处理模块接着对32个通道数据流进行通道纠偏处理(lane de-skew)得到对齐的32条通道数据流。然后根据FEC通道0-3、FEC通道4-7、FEC通道8-11、FEC通道12-15、FEC通道16-19、FEC通道20-23、FEC通道24-27或FEC通道28-31的对齐标识对4条通道的数据进行通道重排序(lane reorder)处理,使得4条通道的数据能够按照指定的顺序排列。最后使得32条通道的数据能够按照指定的顺序排列。一种顺序是跟图8和图9一样通道数据流从上往下按从0到31排序。
应理解,上述发端处理模块对32个通道数据流进行通道纠偏处理得到对齐的32条通道数据流,一种具体实现方式是根据FEC通道0-3、FEC通道4-7、FEC通道8-11、FEC通道12-15、FEC通道16-19、FEC通道20-23、FEC通道24-27或FEC通道28-31已知的对齐标识对4条通道的数据进行现有标准定义的通道纠偏处理(见IEEE 802.3Clause 91或Clause 161),使得第0路、第1路、第2路、第3路、第4路、第5路、第6路或第7路100G中的PCS通道数据流不存在偏差,也即不存在时延。同时利用对齐标识使得八路FEC通道数据流是符号对齐的。此时第0路、第1路、第2路、第3路、第4路、第5路、第6路和第7路之间的FEC通道数据流可以是不存在偏差,也可以是存在偏差。考虑RS符号包含10个比特,对齐后的FEC通道数据流中,第0路、第1路、第2路、第3路、第4路、第5路、第6路和第7路之间的FEC通道数据流存在偏差的比特数目是10的倍数。
在一些具体场景,采用800G或1.6T接口,发端设备将待传输的业务数据流进行KP4RS(544,514)码外码编码得到n条PCS通道数据流。每A个外码码字分布在n条通道数据流中。具体地,n条PCS通道数据流中每条数据流间隔B个符号总共n×B个符号,其包含了A个RS码码字,其中n×B=A×544。每条PCS通道数据流中连续A个符号来自A个不同RS码码字,且连续A条PCS通道数据流的同个位置的A个符号来自A个不同RS码码字,其中整数A可为2、4等。n条PCS通道数据流经PMA处理后通过连接单元接口送入发端处理模块。一些可能的参数组合如下:“n=8,A=2,B=136”、“n=16,A=2,B=68”、“n=8,A=4,B=272”、“n=16,A=4,B=136”。基于上述图3(b)所示的发端处理模块的数据处理示意图,发端处理模块利用n条PCS通道已知的对齐标识进行n个通道数据流的标识锁定。发端处理模块接着对n个通道数据流进行通道纠偏处理得到对齐的n条通道数据流。
图10为本申请实施例提供的数据交织方法的一种流程示意图。
1001、根据n条延迟线分别对n路数据流进行延迟。
图11为本申请实施例中采用延迟器对n条数据流进行延迟的一种结构示意图。如图11所示,该延迟器包括n条延迟线,与n路数据流一一对应。每一路数据流经过对应延迟线的延迟后再送入交织器进行数据交织。需要说明的是,本申请中延迟的取值是以符号为单位来统计的,其中,符号可以包括一个或多个比特。延迟线的延迟取值所包括的符号数量越多,就说明这条延迟线对数据流的延迟(也称为时延)越长。图12为本申请实施例中延迟线的一种结构示意图。如图12所示,延迟线可以包括Q个存储单元(storage element)D,每个存储单元D可存储d个符号,Q和d均为整数。应理解,当延迟线没有包含存储单元时,延迟线的延迟为0个符号,即为无延迟透传。
需要说明的是,本实施例中n为能被p整除的正整数,p为大于1的整数。每条延迟线的延迟取值为延迟取值集合中的任一种延迟取值,延迟取值集合包括p个延迟取值。所述延迟取值集合中最小的延迟取值为0,且所述延迟取值集合的p个延迟取值按从小到大的顺序每相邻两个延迟取值的差值为V个符号,其中,V=Q×d。延迟取值集合中每个延迟取值对应的延迟线的数量为n/p,V为大于或等于34的整数。在一些优选的实现方式中,V也可以为大于或等于68的整数。例如,n=32,p=4,延迟取值集合包括0,V,2V和3V共4种延迟取值,每条延迟线的延迟取值只能是这4种延迟取值中的任一种,并且0,V,2V和3V这4种延迟取值对应的延迟线数量均为8条。
在一些可能的实施方式中,在根据n条延迟线分别对n路数据流进行延迟之前,还将对n路数据流进行通道重排序,以使得n路数据流按照预设顺序排列。在另一些可能的实施方式中,在根据n条延迟线分别对n路数据流进行延迟之后,还将对n路数据流进行通道重排序,以使得n路数据流按照预设顺序排列。以32条数据流为例,32条数据流可以是按照0到31排序从上到下排列,当然可以简单扩展到其他顺序排列,其具体实现方式本领域普通技术人员可知,此处不再赘述。应理解,基于n条数据流排序的不同,也会相应设计不同的延迟线分布规则,在保证性能的基础上还可以尽量降低延迟,后面会对本申请提供的延迟线分布规则进行详细介绍。
在一些可能的实施方式中,在根据n条延迟线分别对n路数据流进行延迟之前,还将对n路数据流进行通道纠偏处理,以获得n条对齐的通道数据流。对于n条数据流为多路业务数据流时,n条对齐的通道数据流满足如下约束:每路业务数据流中的多条通道数据流不存在偏差,各路业务数据流之间的通道数据流是符号对齐的。在一些具体实现方式,通道纠偏处理模块利用先进先出(First input first output,FIFO)进行缓存数据。考虑所设计的延迟处理中的延迟线采用存储单元实现,为了降低硬件实现复杂度和功耗,可将通道纠偏处理和延迟处理合并一起实现,采用一套FIFO同时实现纠偏处理和延迟处理。
还需要说明的是,输入延迟器的n条数据流都为经过FEC编码的数据流,也就是上文中介绍的经过外码编码的数据流。具体地,该外码编码可以采用RS码,经过外码编码后的n条数据流可以包括多个RS码字。在实际应用中也可以采用其他的编码方式进行外码编码,为了便于描述,下文统一用RS码字来表示外码编码后生成的码字。
1002、从延迟后的n路数据流各获取L×m个符号以得到L个第一符号集合。
交织器可以从延迟后的n路数据流各获取L×m个符号以得到L个第一符号集合,其中,L为大于或等于1的整数,m为大于或等于1的整数。也就是说,每个第一符号集合包括n×m个符号。交织器可以每次获取n×m个符号以得到第一符号集合,并重复执行L次从而得到L个第一符号集合。或者,交织器也可以一次读取L×n×m个符号以得到L个第一符号集合。应理解,交织器中可以设有L块缓存,分别用于存储L个第一符号集合。具体地,每个第一符号集合可以包括多个第一符号子集。例如,每个第一符号集合包括n个第一符号子集,每个第一符号子集包括依次排列的m个符号。又例如,每个第一符号集合包括m个第一符号子集,每个第一符号子集包括依次排列的n个符号。为了便于描述,下文统一按照每个第一符号集合包括n个第一符号子集为例进行介绍,本领域的技术人员可以直接推导出第一符号集 合包括m个第一符号子集的另一种描述方式,后面不再结合另一种描述方式进行逐一介绍。可选地,第一符号集合中第h个第一符号子集的m个符号来自延迟后的第h路数据流,其中,0≤h≤n-1。
需要说明的是,上述第一符号子集只是为了便于描述而引入的概念,在实际应用中,第一符号集合为一个整体并不存在划分,每个第一符号子集可以视作从第一符号集合中选取的一个或多个符号。
在一种可能的实施方式中,该第一符号集合是以一条数据流的形式呈现,即第一符号集合中的符号排列形成一条数据流。在另一种可能的实施方式中,该第一符号集合是以符号矩阵的形式呈现。具体地,第一符号集合表示为第一符号矩阵,第一符号矩阵包括n行m列个符号。该第一符号矩阵中每一行的m个符号可以理解为是一个第一符号子集。也就是说,第一符号矩阵本质上也是多个符号的集合,引入第一符号矩阵只是换了一个维度进行介绍,第一符号集合中某个第一符号子集中的某个符号也可以简单地转换为第一符号矩阵中某一行某一列的符号。为了便于介绍,下文中只会以第一符号集合或第一符号矩阵中的一种形式来进行描述,本领域的技术人员可以根据上文介绍的第一符号集合与第一符号矩阵的对应关系直接推导出另一种形式的描述。
1003、对L个第一符号集合分别进行交织得到L个第二符号集合。
交织器对L个第一符号集合分别进行交织得到L个第二符号集合。每个第二符号集合可以包括多个第二符号子集。例如,每个第二符号集合包括r个第二符号子集,每个第二符号子集包括c个符号。又例如,每个第二符号集合包括c个第二符号子集,每个第二符号子集包括r个符号。其中,r为大于1的整数,c为大于1的整数,n×m=r×c,即第一符号集合中的符号数量与第二符号集合中的符号数量相同。为了便于描述,下文统一按照每个第二符号集合包括r个第二符号子集为例进行介绍,本领域的技术人员可以直接推导出第二符号集合包括c个第二符号子集的另一种描述方式,后面不再结合另一种描述方式进行逐一介绍。具体地,每个第二符号子集中的c个符号对应第一符号集合中分布在c个第一符号子集的c个符号,以使得每个第二符号子集中的c个符号尽可能来自更多个不同的RS码字,以实现更好的数据交织效果。后面会对本申请提供的数据交织规则进行详细介绍。
需要说明的是,上述第二符号子集只是为了便于描述而引入的概念,在实际应用中,第二符号集合为一个整体并不存在划分,每个第二符号子集可以视作从第二符号集合中选取的一个或多个符号。
在一种可能的实施方式中,该第二符号集合是以一条数据流的形式呈现,即第二符号集合中的符号排列形成一条数据流。在另一种可能的实施方式中,该第二符号集合是以符号矩阵的形式呈现。具体地,第二符号集合表示为第二符号矩阵,第二符号矩阵包括r行c列个符号。该第二符号矩阵中的每一行的c个符号可以理解为是一个第二符号子集。第二符号矩阵中每一行的c个符号对应第一符号矩阵中分布在c行的c个符号。也就是说,第二符号矩阵本质上也是多个符号的集合,引入第二符号矩阵只是换了一个维度进行介绍,第二符号集合中某个第二符号子集中的某个符号也可以简单地转换为第二符号矩阵中某一行某一列的符号。为了便于介绍,下文中只会以第二符号集合或第二符号矩阵中的一种形式来进行描述,本领域的技术人员可以根据上文介绍的第二符号集合与第二符号矩阵的对应关系直接推导出 另一种形式的描述。
需要说明的是,交织器对L个第一符号集合分别进行交织得到L个第二符号集合之后,交织器将向编码装置输出L个第二符号集合。进而,编码装置分别对每个第二符号集合中r个第二符号子集进行FEC编码得到L×r个码字,也就是上文介绍的进行内码编码。在一种可能的实施方式中,编码装置采用汉明码分别对L个第二符号集合中r个第二符号子集进行FEC编码得到L×r个汉明码子。
本申请实施例中,n路数据流都为经过外码编码后的码字,在对n路数据流分别进行延迟之后,还将对延迟后的n路数据流进行数据交织。采用本申请提供的延迟处理方案,通过较短的时延就能实现延迟后的n路数据流在同一时刻输出的n个符号来自多个不同的外码码字,在保证较好性能的基础上也有助于降低数据交织的时延。也就是说,本申请中延迟处理与数据交织相结合的方案所采用的整体时延较低,更适用于要求低时延的应用场景。
下面对本申请提供的对n路数据流进行延迟的具体实现方式进行介绍。
需要说明的是,下面将以n能被16整除且p=4为例进行介绍,n条延迟线将包括至少一组,每一组包括16条相邻的延迟线。也就是说,本申请是以一组16条延迟线为颗粒度来介绍延迟线的分布规则。应理解,数据流与延迟线是一一对应的,n条延迟线的顺序与对应的n条数据流的顺序是保持一致。如果通道重排序后的数据流是按照0,1,2,3…的顺序排列,那么延迟线也是按照0,1,2,3…的顺序排列。如果数据流按照其他顺序排列,延迟线也会按照相应的顺序排列。而且,第k(0≤k<n/16)组延迟包含延迟线16*k,延迟线16*k+1,…,延迟线16*k+15。其中对于相邻4条延迟线满足的约束存在多种情况,比如延迟线16*k和延迟线16*k+1满足所设计约束且延迟线16*k+2和延迟线16*k+3满足另一所设计约束,或者延迟线16*k和延迟线16*k+3满足所设计约束且延迟线16*k+1和延迟线16*k+2满足另一所设计约束。考虑到在介绍延迟线规则时的选取延迟线的顺序不唯一,为了便于介绍本申请所提供的延迟线分布规则,这里将每一组16条延迟线的编号分别记为a 0、a 1、a 2、a 3、a 4、a 5、a 6、a 7、a 8、a 9、a 10、a 11、a 12、a 13、a 14、a 15,其中,a 0、a 1、a 2、a 3、a 4、a 5、a 6、a 7、a 8、a 9、a 10、a 11、a 12、a 13、a 14、a 15互不相等且均为小于16的非负整数。也就是说,a 0-a 15的编号取值可以是与0-15按顺序一一对应,即{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}。除此之外,a 0-a 15的编号取值可以不按照0-15的顺序,例如{0,3,1,2,4,7,5,6,8,11,9,10,12,15,13,14}等。
应理解,若n大于或等于32,n条延迟线包括多组,例如,第0组延迟线,第一组延迟线等。其中,第0组延迟线的编号a 0-a 15是从0-15中取值,第1组延迟线的编号a 0-a 15是从16-31中取值,以16个编号为一组以此类推。为了便于介绍,无论是第几组延迟线,下文中都以该组延迟线的编号a 0-a 15是从0-15中取值来说明,该组延迟线实际的编号就是在a 0-a 15的基础上每个编号都加16*k即可,0≤k<n/16。也就是说,第k组延迟线的编号取值为a 0+16*k,a 1+16*k,…,a 15+16*k。另外,不同组的16条延迟线的编号排序可以相同,也可以不同。以n=32为例,32条延迟线包括第0组的16条延迟线的编号取值a 0-a 15为{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15},即0-15按顺序排列。而第1组的16条延迟线的编号排序可以是按照与第0组延迟线一致的0-15顺序排列,也可以采用 其他顺序的编号取值,具体此处不做限定。
在一种可能的实施方式中,第k组(0≤k<n/16)延迟线中第a 0条延迟线、第a 1条延迟线、第a 2条延迟线、第a 3条延迟线、第a 4条延迟线、第a 5条延迟线、第a 6条延迟线、第a 7条延迟线、第a 8条延迟线、第a 9条延迟线、第a 10条延迟线、第a 11条延迟线、第a 12条延迟线、第a 13条延迟线、第a 14条延迟线和第a 15条延迟线的延迟取值满足第一条件,具体地,该第一条件为:

第a 14条延迟线的延迟取值和第a 15条延迟线的延迟取值相差2V个符号。
需要说明的是,对于客户侧为每个通道100Gb/s的8×100G接口且采用“100G RS-FEC”模式。若满足上述第一条件且V≥68时,32条数据流中的数据流0-15(或数据流16-31)经过延迟处理后每一次分别输出的16个符号中第a 0个符号和第a 1个符号来自2个不同的RS码字符号,第a 2个符号和第a 3个符号来自2个不同的RS码字符号,…,第a 14个符号和第a 15个符号来自2个不同的RS码字符号,通过这种延迟设计方式便于后面采用实现简单且时延较低的交织处理方案以实现较好的级联FEC方案性能,减少整体传输方案时延。
在上述基础上,每一组16条延迟线中,延迟取值为0个符号、V个符号、2V个符号和3V个符号的延迟线数量均为4。

第a 0条延迟线的延迟取值、第a 4条延迟线的延迟取值、第a 8条延迟线的延迟取值和第a 12条延迟线的延迟取值互不相等,第a 1条延迟线的延迟取值、第a 5条延迟线的延迟取值、第a 9条延迟线的延迟取值和第a 13条延迟线的延迟取值互不相等,第a 2条延迟线的延迟取值、第a 6条延迟线的延迟取值、第a 10条延迟线的延迟取值和第a 14条延迟线的延迟取值互不相等,第a 3条延迟线的延迟取值、第a 7条延迟线的延迟取值、第a 11条延迟线的延迟取值和第a 15条延迟线的延迟取值互不相等。
需要说明的是,对于客户侧为每个通道100Gb/s的1×800G接口或2×400G接口。若满足上述第二条件且V≥68时,32条数据流中的数据流0-15(或数据流16-31)经过延迟处理后每一次分别输出的16个符号中第a 0个符号、第a 4个符号、第a 8个符号、第a 12个符号来自4个不同的RS码字符号,第a 1个符号、第a 5个符号、第a 9个符号、第a 13个符号来自4个不同的RS码字符号,第a 2个符号、第a 6个符号、第a 10个符号、第a 14个符号来自4个不同的RS码字符号,第a 3个符号、第a 7个符号、第a 11个符号、第a 15个符号来自4个不同的RS码字符 号,通过这种延迟设计方式便于后面采用实现简单且时延较低的交织处理方案以实现较好的级联FEC方案性能,减少整体传输方案时延。
在上述基础上,第k组(0≤k<n/16)延迟线中第a 0条延迟线、第a 2条延迟线、第a 4条延迟线、第a 6条延迟线、第a 8条延迟线、第a 10条延迟线、第a 12条延迟线和第a 14条延迟线的延迟取值满足第三条件,具体地,该第三条件为:

需要说明的是,对于客户侧为每个通道100Gb/s的4×200G接口。若满足上述第一和第三条件且V≥68时,32条数据流中的数据流0-15(或数据流16-31)经过延迟处理后每一次分别输出的16个符号中第a 0个符号、第a 1个符号、第a 4个符号、第a 5个符号来自4个不同的RS码字符号,且第a 2个符号、第a 3个符号、第a 6个符号、第a 7个符号来自4个不同的RS码字符号。第a 8个符号、第a 9个符号、第a 12个符号、第a 13个符号来自4个不同的RS码字符号,且第a 10个符号、第a 11个符号、第a 14个符号、第a 15个符号来自4个不同的RS码字符号,通过这种延迟设计方式便于后面采用实现简单且时延较低的交织处理方案以实现较好的级联FEC方案性能,减少整体传输方案时延。

下面提供几个具体地实施例对上述图10所描述的数据交织方法的完整流程进行介绍。
实施例1:n=32,32条延迟线包括2组,每组包括16条延迟线。每组16条延迟线a 0、a 1、a 2、a 3、a 4、a 5、a 6、a 7、a 8、a 9、a 10、a 11、a 12、a 13、a 14和a 15的编号取值为{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}。32个第一符号子集b 0、b 1、b 2、b 3、b 4、b 5、b 6、b 7、b 8、b 9、b 10、b 11、b 12、b 13、b 14、b 15、b 16、b 17、b 18、b 19、b 20、b 21、b 22、b 23、b 24、b 25、b 26、b 27、b 28、b 29、b 30和b 31的编号取值为{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31}。
图13为本申请实施例中32条延迟线的一种分布示意图。如图13所示,32条数据流分别对应32条延迟线,延迟线可以包括0、Q、2Q或3Q个存储单元D,每个存储单元D存储可存储d个符号。即延迟线的延迟取值可以为0、V个符号、2V个符号或3V个符号,其中V=Q*d。每组16条延迟线中第a 0条延迟线、第a 1条延迟线、第a 2条延迟线、第a 3条延迟线、第a 4条延迟线、第a 5条延迟线、第a 6条延迟线、第a 7条延迟线、第a 8条延迟线、第a 9条延迟线、第a 10条延迟线、第a 11条延迟线、第a 12条延迟线、第a 13条延迟线、第a 14条延迟线和第a 15条延迟线的的延迟取值为{0,2V,0,2V,2V,0,2V,0,V,3V,V,3V,3V,V,3V,V}。相应的,延迟线0-31的延迟符号个数分别为{0,2V,0,2V,2V,0,2V,0,V,3V,V,3V,3V,V,3V,V,0,2V,0,2V,2V,0,2V,0,V,3V,V,3V,3V,V,3V,V}。具体地,延迟器从每一条延迟线最右边的存储单元输出d个符号以得到32*d个符号。相应的,每一条延迟线中存储单元存储的符号均向右移位d个符号。进而,32条数据流中将各自获取d个符号分别写入32条延迟线中最左边的存储单元。应理解,当延迟线包含0个存储单元(如图13中延迟线0、2、5、7、16、18、21、23),该延迟线输出的d个符号为当前操作从对应的PCS或FEC通道数据流中获取的d个符号。应理解,每条延迟线一次延迟操作输出d个符号,当d≤L*m时,可重复执行

其中
Figure PCTCN2022110483-appb-000086
为正整数。
交织器从延迟后的32条数据流各获取L*m个符号,得到L个第一符号集合。每个第一符号集合包含32个第一符号子集,每个第一符号子集包含m个符号。每个第一符号集合的第h个(0≤h<32)第一符号子集中m个符号来自从延迟后的数据流h。交织器对L个第一符号集合分别进行交织得到L个第二符号集合,其中,第二符号集合包含r×c个符号。每个第二符号集合包含r个第二符号子集,每个第二符号子集包含c个符号,其中,32×m=r×c。
需要说明的是,第一符号集合也可以是一个包含32行m列符号的符号矩阵,称为第一符号矩阵。第二符号集合也可一个包含r行c列符号的符号矩阵,称为第二符号矩阵。此时,从延迟后的数据流h获取的L*m个符号分别送入L个第一符号矩阵中第h行的m列。每个第一符号矩阵第h行共m个符号各来自延迟后的数据流h。交织器对L个第一符号矩阵的32×m个符号分别进行交织得到L个第二符号矩阵,其中,第二符号矩阵包含r行c列个符号。

本实施例中,当L=1且d=1时,32条延迟线中最长延迟为3V=3Q×d=3*68*1=204个符号,即2040比特。当L=5且d=5时,32条延迟线中最长延迟为3V=3Q×d=3*14*5=210个符号,即2100比特。所需的延迟较短。当内码编码采用Hamming(170,160)时,每个Hamming信息位160个比特总共16个符号。对于客户侧接口为每个通道100Gb/s的1×800G,2×400G,4×200G或8×100G,每个Hamming信息位的16个符号来自于16个不同外码码字,使得整体级联FEC方案性能较好。应理解,在某些要求超低时延的场景中,可以采用更低的V取值,此时每个Hamming信息位的16个符号来自于少于16个不同外码码字符号,性能稍有劣化,但其对应的整体传输时延较低。
实施例2:n=32,32条延迟线包括2组,每组包括16条延迟线。每组16条延迟线a 0、a 1、a 2、a 3、a 4、a 5、a 6、a 7、a 8、a 9、a 10、a 11、a 12、a 13、a 14和a 15的编号取值为{0,3,1,2,4,7,5,6,8,11,9,10,12,15,13,14}。32个第一符号子集b 0、b 1、b 2、b 3、b 4、b 5、 b 6、b 7、b 8、b 9、b 10、b 11、b 12、b 13、b 14、b 15、b 16、b 17、b 18、b 19、b 20、b 21、b 22、b 23、b 24、b 25、b 26、b 27、b 28、b 29、b 30和b 31的编号取值为{0,3,1,2,4,7,5,6,8,11,9,10,12,15,13,14,16,19,17,18,20,23,21,22,24,27,25,26,28,31,29,30}。

需要说明的是,第一符号集合也可以是一个包含32行m列符号的符号矩阵,称为第一符号矩阵。第二符号集合也可一个包含r行c列符号的符号矩阵,称为第二符号矩阵。此时,从延迟后的数据流h获取的L*m个符号分别送入L个第一符号矩阵中第h行的m列。每个第一符号矩阵第h行共m个符号各来自延迟后的数据流h。交织器对L个第一符号矩阵的32×m个符号分别进行交织得到L个第二符号矩阵,其中,第二符号矩阵包含r行c列个符号。

列的符号,0≤i<8,0≤j<12,0≤x<96。交织器输出2个第二符号矩阵后,编码装置将分别对2个第二符号矩阵中每行的12个符号进行内码编码得到16个码字。当内码编码采用Hamming(128,120)时,交织器输出的192个符号总共1920个比特进行内码编码后可得到16个内码码字,总共16×128=2048个比特。
本实施例中,32条延迟线中最长延迟为3V=3Q×d=216个符号,即2160比特,所需的延迟较短。当内码编码采用Hamming(128,120)时,每个Hamming信息位120个比特总共12个符号。对于客户侧接口为每个通道100Gb/s的1×800G,2×400G,4×200G或8×100G,每个Hamming信息位的12个符号来自于不少于10个不同外码码字,使得整体级联FEC方案性能较好。

实施例4:区别于实施例3,本实施例4采用不同的交织规则。第一符号矩阵包括32行3列个符号,第二符号矩阵包括8行12列个符号,且L=2、Q=12、d=6。即交织器从延迟后的32条数据流中各获取6个符号,延迟线中每个存储单元D存储d=6个符号,每个符号包括10个比特。V=Q*d=72,每条延迟线的延迟取值为0个符号、72个符号、144个符号或216个符号。具体地,32条延迟线的延迟取值可以如实施例3中表15所示。第二符号矩阵中第i行第j列(0≤i<8,0≤j<12)的符号来自第一符号矩阵中第b x%32=x%32行第

交织器输出2个第二符号矩阵后,内码编码装置将分别对2个第二符号矩阵中每行的12个符号进行内码编码得到16个码字。当内码编码采用Hamming(128,120)时,交织器输出的192个符号总共1920个比特进行内码编码后可得到16个内码码字,总共16×128=2048个比特。
本实施例中,32条延迟线中最长延迟为3V=3Q×d=216个符号,即2160比特,所需的延迟较短。当内码编码采用Hamming(128,120)时,每个Hamming信息位120个比特总共12个符号。对于客户侧接口为每个通道100Gb/s的1×800G,2×400G,4×200G或8×100G,每个Hamming信息位的12个符号来自于12个不同外码码字,使得整体级联FEC方案性能较好。
实施例5:n=32,32条延迟线包括2组,每组包括16条延迟线。
如上图13所示,32条数据流分别对应32条延迟线,延迟线可以包括0、Q、2Q或3Q个存储单元D,每个存储单元D存储可存储d个符号。即延迟线的延迟取值可以为0、V个符号、2V个符号或3V个符号,V为大于或等于68的整数。具体地,延迟器从每一条延迟线最右边的存储单元输出d个符号以得到32*d个符号。相应的,每一条延迟线中存储单元存储的符号均向右移位d个符号。进而,32条数据流中将各自提取d个符号分别写入32条延迟线中最左边的存储单元。应理解,当延迟线包含0个存储单元,该延迟线输出的d个符号为当前操作从对应的PCS或FEC通道数据流中获取的d个符号。应理解,每条延迟线一次延迟操作输出d个符号,当d≤L*m时,可重复执行

交织器从延迟后的32条数据流各获取L*m个符号,得到L个第一符号集合。每个第一符号集合包含32个第一符号子集,每个第一符号子集包含m个符号。每个第一符号集合的第h个(0≤h<32)第一符号子集中m个符号来自从延迟后的数据流h。交织器对L个第一符号集合分别进行交织得到L个第二符号集合,其中,第二符号集合包含r×c符号。每个第二符号集合包含r个第二符号子集,每个第二符号子集包含c个符号,其中,32×m=r×c。
需要说明的是,第一符号集合也可以是一个包含32行m列符号的符号矩阵,称为第一符号矩阵。第二符号集合也可一个包含r行c列符号的符号矩阵,称为第二符号矩阵。此时,从延迟后的数据流h获取的L×m个符号分别送入L个第一符号矩阵中第h行的m列。每个第一符号矩阵第h行共m个符号各来自延迟后的数据流h。交织器对L个第一符号矩阵的32×m个符号分别进行交织得到L个第二符号矩阵,其中,第二符号矩阵包含r行c列个符号。
如图14所示,在一种可能的实施方式中,交织器包括L个交织子单元,L个交织子单元分别对L个第一符号矩阵进行交织获得L个第二符号矩阵。具体地,数据划分单元

从延迟后的数据流h(0≤h<32)获取到L×m个符号,L×m个符号包括L组,每组m个符号。L组符号分别送入L个第一符号矩阵中第h行。在另一种可能的实施方式中,交织器无需划分多个交织子单元,交织器对第一符号矩阵进行交织得到第二符号矩阵,并重复L次该操作以得到L个第二符号矩阵。
作为一个示例,第一符号矩阵包括32行16列个符号,第二符号矩阵包括32行16列个 符号,且L=1、Q=9、d=8。即交织器从延迟后的32条数据流中各获取16个符号,延迟线中每个存储单元D存储d=8个符号,每个符号包括10个比特。V=Q×d=72,每条延迟线的延迟取值为0个符号、72个符号、144个符号或204个符号。具体地,32条延迟线的延迟取值可以如下表18所示。

本实施例中,32条延迟线中最长延迟为3Q×d=240个符号,即2400比特,所需的延迟较短。当结合表16的延迟取值和表17的交织规则内码编码采用Hamming(170,160)时,每个Hamming信息位160个比特总共16个符号。对于客户侧接口为每个通道100Gb/s的1×800G,2×400G,4×200G或8×100G,每个Hamming信息位的16个符号来自于16个不同外码码字, 使得整体级联FEC方案性能较好。而当结合表18的延迟取值和表19的交织规则内码编码采用Hamming(128,120)时,每个Hamming信息位120个比特总共12个符号。对于客户侧接口为每个通道100Gb/s的1×800G,2×400G,4×200G或8×100G,每个Hamming信息位的12个符号来自于12个不同外码码字,使得整体级联FEC方案性能较好。
需要说明的是,上述实施例给出了内码信息符号长度c=8、12和16个符号的情况,也可拓展到内码信息符号长度为9、10、11、13、14、15的其他情况。32条数据流经过延迟处理后每一次分别输出的32个符号中第0组16个符号来自16个不同的RS码字符号。第0组16个符号包括:第b 0个符号、第b 1个符号、第b 4个符号、第b 5个符号、第b 8个符号、第b 9个符号、第b 12个符号、第b 13个符号、第b 16个符号、第b 17个符号、第b 20个符号、第b 21个符号、第b 24个符号、第b 25个符号、第b 28个符号、第b 29个符号。32条数据流经过延迟处理后每一次分别输出的32个符号中第1组16个符号来自16个不同的RS码字符号。第1组16个符号包括:第b 2个符号、第b 3个符号、第b 6个符号、第b 7个符号、第b 10个符号、第b 11个符号、第b 14个符号、第b 15个符号、第b 18个符号、第b 19个符号、第b 22个符号、第b 23个符号、第b 26个符号、第b 27个符号、第b 30个符号、第b 31个符号。
或者,第0组16个符号包括:第b 0个符号、第b 1个符号、第b 4个符号、第b 5个符号、第b 8个符号、第b 9个符号、第b 12个符号、第b 13个符号、第b 18个符号、第b 19个符号、第b 22个符号、第b 23个符号、第b 26个符号、第b 27个符号、第b 30个符号、第b 31个符号。第1组16个符号包括:第b 2个符号、第b 3个符号、第b 6个符号、第b 7个符号、第b 10个符号、第b 11个符号、第b 14个符号、第b 15个符号、第b 16个符号、第b 17个符号、第b 20个符号、第b 21个符号、第b 24个符号、第b 25个符号、第b 28个符号、第b 29个符号。
结合上述特征,可通过设计交织器使得交织器每行输出的c个符号来自c个不同的RS码字符号。下面以b i=i为例给出一种交织方式。第一符号矩阵包含32行m列,第二符号矩阵包含r行c列,且32*m=r*c。第一符号矩阵中第0组的16行符号依次包括第0、1、4、5、8、9、12、13、16、17、20、21、24、25、28、29行中符号。第一符号矩阵中第1组的16行符号依次包括第2、3、6、7、10、11、14、15、18、19、22、23、26、27、30、31行中符号。
具体地,所述第0组16行符号中每列的第0行到第15行为按所述顺序排列的16个符号,所述第0组16行符号的相邻两列中前一列的第15行到后一列的第0行为按所述顺序排列的2个符号,所述第二符号矩阵的第0组r/2行符号中第0行的c个符号来自所述第0组16行符号中从第0行第0列开始按所述顺序排列的第0组c个符号,依次类推,直到所述第二符号矩阵的第0组r/2行符号中第r/2-1行的c个符号来自所述第0组16行符号中从第0行第0列开始按所述顺序排列的最后一组c个符号。也就是说,第0组16行符号是按先从上往下后从左往右的方式依次获取c个符号作为第二符号矩阵中的一行,总共得到第二符号矩阵中r/2行。
同理,所述第二组16行符号按顺序排列,所述第1组16行符号中每列的第0行到第15行为按所述顺序排列的16个符号,所述第1组16行符号的相邻两列中前一列的第15行到后一列的第0行为按所述顺序排列的2个符号,所述第二符号矩阵的第1组r/2行符号中第0行的c个符号来自所述第1组16行符号中从第0行第0列开始按所述顺序排列的第0组c个符号,依次类推,直到所述第二符号矩阵的第1组r/2行符号中第r/2-1行的c个符号来自 所述第1组16行符号中从第0行第0列开始按所述顺序排列的最后一组c个符号。也就是说,第1组16行符号是按先从上往下后从左往右的方式依次获取c个符号,作为第二符号矩阵中的一行,总共得到第二符号矩阵中的r/2行。
更具体地,下面给出几种典型的参数组合:{m=9,r=32,c=9}、{m=5,r=16,c=10}、{m=11,r=32,c=11}、{m=13,r=32,c=13}、{m=7,r=16,c=14}、{m=15,r=32,c=15}。
需要说明的是,除了上述介绍的数据交织方法外,本申请还提供了另一种基于数据流分组的数据交织方法,下面进行介绍。
图18为本申请实施例中一种对数据流进行分组的示意图。如图18所示,将n条数据流包含g组,每一组包括p条数据流。其中,g为大于或等于1的整数,p为大于或等于1的整数,n=g×p。具体地,数据流0、数据流1、…、数据流p-1属于同一组。数据流p、数据流p+1、…、数据流2p-1属于同一组。以此类推,数据流(g-1)p、数据流(g-1)p+1、…、数据流n-1属于同一组。相应的,延迟器中的n条延迟线也对应的包括g组,每一组包括p条延迟线。g组延迟线与g组数据流一一对应,每组延迟线中的p条延迟线分别包括0个存储单元、Q个存储单元、2Q个存储单元、…、(p-1)Q个存储单元,每个存储单元用于存储d个符号。其中,Q为大于或等于1的整数,d为大于或等于1的整数。也就是说,每组延迟线中的p条延迟线分别对应p个延迟取值,分别为0个符号、V个符号、2V个符号、…、(p-1)V个符号,其中,V=Q×d。
图19为本申请实施例中一组延迟线的其中一种结构示意图。如图19所示,第0条延迟线具有(p-1)Q个存储单元,之后按照组内排序,每一条延迟线依次减少Q个存储单元,即第p-1条延迟线具有0个存储单元。图20为本申请实施例中一组延迟线的另一种结构示意图。如图20所示,第0条延迟线具有0个存储单元,之后按照组内排序,每一条延迟线依次增加Q个存储单元,即第p-1条延迟线具有(p-1)Q个存储单元。应理解,上述图19和图20只是提供了组内延迟线分配的两个示例,在实际应用中,只要满足每组延迟线中的p条延迟线分别对应p个延迟取值即可,也可以不采用上述依次递减或依次递增的延迟线分配方式,此处不再一一列举。
基于上述对延迟线的分组,相应的也需要对第一符号矩阵和第二符号矩阵进行分组。图21(a)为本申请实施例中对第一符号矩阵和第二符号矩阵进行分组的示意图。如图21(a)所示,第一符号矩阵中每一列的n个符号包括g个组,每一组包括p个符号。第二符号矩阵中每一行的c个符号包括s个组,每一组包括p个符号。其中,g为大于1的整数,s为大于1的整数,p为大于或等于1的整数。具体地,第二符号矩阵的其中一组p个符号来自第一符号矩阵的其中一组p个符号,并且,第二符号矩阵的每行中任意两组共2p个符号来自第一符号矩阵中的不同行。例如,如果第二符号矩阵中第0行第0组的p个符号来自第一符号矩阵中第0列第0组的p个符号,则第二符号矩阵中第0行其他组的符号不能来自第一符号矩阵中所有列中第0组的符号。
图21(b)为本申请实施例中另一种对第一符号矩阵和第二符号矩阵进行分组的示意图。如图21(b)所示,第一符号矩阵包含g个第一符号子矩阵,每个第一符号子矩阵包含p行m列,其中,g、p、m为大于或等于1的整数,且n=p×g。第二符号矩阵包含g个第二符号子 矩阵,每个第二符号子矩阵包含r0行c列,其中,r0、c为大于或等于1的整数,且r=r0×g,p×m=r0×c。第一符号子矩阵i(0≤i<g)进行交织得到第二符号子矩阵i。每个所述第二符号矩阵中每行c个符号来自c个不同的码字。
考虑一些具体场景,发端设备将待传输的业务数据流进行KP4RS(544,514)码外码编码得到n条PCS通道数据流,每A个外码码字分布在n条通道数据流中。具体地,n条PCS通道数据流中每条数据流间隔B个符号总共n×B个符号,其包含了A个RS码码字,其中n×B=A×544。每条PCS通道数据流中连续A个符号来自A个不同RS码码字,且连续A条PCS通道数据流的同个位置的A个符号来自A个不同RS码码字,其中整数A可为2、4等。n条PCS通道数据流经PMA处理后通过连接单元接口送入发端处理模块。在发端处理模块中,经过通道纠偏处理后得到n条对齐通道数据流。采用图18所示的延迟器,其包含g组延迟线,每组延迟线中的p条延迟线分别对应p个延迟取值,分别为0个符号、V个符号、2V个符号、…、(p-1)V个符号,其中,V=Q×d。当V≥b时,每组p条延迟线输出符号中的A×p个符号来自A×p个不同的RS外码码字,其中每条延迟线提供连续A个符号。
交织器从延迟后的n条数据流各获取L*m个符号,得到L个第一符号集合。每个第一符号集合包含n个第一符号子集,每个第一符号子集包含m个符号。每个第一符号集合的第h个(0≤h<n)第一符号子集中m个符号来自从延迟后的数据流h。交织器对L个第一符号集合分别进行交织得到L个第二符号集合,其中,第二符号集合包含r×c个符号。每个第二符号集合包含r个第二符号子集,每个第二符号子集包含c个符号,其中,n×m=r×c。需要说明的是,第一符号集合也可以是一个包含n行m列符号的符号矩阵,称为第一符号矩阵。第二符号集合也可一个包含r行c列符号的符号矩阵,称为第二符号矩阵。此时,从延迟后的数据流h获取的L*m个符号分别送入L个第一符号矩阵中第h行的m列。每个第一符号矩阵第h行共m个符号各来自延迟后的数据流h。交织器对L个第一符号矩阵的n×m个符号分别进行交织得到L个第二符号矩阵,其中,第二符号矩阵包含r行c列个符号。
从延迟后的n路数据流各获取L×m个符号以得到L个第一符号矩阵。采用如图21(b)所示交织器对L个第一符号矩阵分别进行交织得到L个第二符号矩阵。第一符号矩阵包含g个第一符号子矩阵,第二符号矩阵包含g个第二符号子矩阵。每个第一符号子矩阵分别进行交织得到第二符号子矩阵。具体地,第二符号子矩阵中每行c个符号来自于第一符号子矩阵中的c个符号,且所述的第一符号子矩阵中的c个符号分布在第一子矩阵中不多于A列中。
在一种可能的实施方式中,所述第t个第一符号子矩阵中的符号按顺序排列,所述第t个第一符号子矩阵中每列的第0行到第p-1行为按所述顺序排列的p个符号,所述第t个第一符号子矩阵的相邻两列中前一列的第p-1行到后一列的第1行为按所述顺序排列的2个符号,所述第t个第二符号子矩阵中第0行的c个符号来自所述第t个第一符号子矩阵中从第0行第0列开始按所述顺序排列的第0组c个符号,依次类推,直到所述第t个第二符号子矩阵中第r0-1行的c个符号来自所述第t个第一符号子矩阵中从第0行第0列开始按所述顺序排列的最后一组c个符号。也就是说,从第一符号子矩阵中按照先从上往下后从左往右的方式依次每行获取
Figure PCTCN2022110483-appb-000131
个符号,总共获取c个符号组成第二符号子矩阵中的一行c个符号,其中
Figure PCTCN2022110483-appb-000132
此时,第二符号子矩阵中每行c个符号来自c个不同的外码RS码字。采用上述方案,整体级联FEC方案性能较好。
需要说明的是,交织器输入的L个第一符号矩阵可以分别存储在交织器中的L个缓存中,交织器完成交织后将输出L个第二符号矩阵至编码器。编码器将对L个第二符号矩阵中每一行的符号分别进行内码编码。具体地,L个第二符号矩阵包括L×r行符号,编码器可以通过L×r个独立的编码单元分别对L×r行符号进行内码编码。
下面通过一些具体的应用场景对这种基于数据流分组的数据交织方法进行进一步介绍。需要说明的是,本申请不限定一个符号所包括的比特数,以下的示例均按照一个符号包括10个比特来介绍。
应用场景1:图22为本申请实施例中数据交织的一种应用场景示意图。如图22所示,n=32,m=3,r=8,c=12,p=4,g=8,s=3。即第一符号矩阵包括32行3列个符号,每一列中4个符号为一组。第二符号矩阵包括8行12列个符号,每一行中4个符号为一组。延迟器中包括32条延迟线,每4条延迟线为一组,每一组的4条延迟线分别包括0个存储单元、Q个存储单元、2Q个存储单元和3Q个存储单元。其中,Q=136,d=1,L=1。应理解,图22中每一组4条延迟线的结构分布只是一个示例,可以按照上述图19和图20介绍的方式进行变形,此处不再赘述。
具体地,交织器从每一条延迟线最右边的存储单元获取出d=1个符号以得到32个符号。相应的,每一条延迟线中存储单元存储的符号均向右移位d=1个符号。进而,32条数据流中将各自提取d=1个符号分别写入32条延迟线中最左边的存储单元。延迟器每次输出的32号符号存储至交织器缓存中的一列。通过重复3次上述操作,交织器缓存中总共写入32×3=96个符号,即第一符号矩阵。交织器对第一符号矩阵进行交织后得到8×12个符号,即第二符号矩阵。
需要说明的是,第二符号矩阵的每行12个符号中每组4个符号均来自于第一符号矩阵的某一列中某一组的4个符号,而且第二符号矩阵中每行3组符号中任意两组符号来自于第一符号矩阵中不同行的两组符号。在一种可能的实施方式中,第二符号矩阵的其中一行12个符号分别对应第一符号矩阵的第0列中第a组的4个符号、所述第一符号矩阵的第1列中第b组的4个符号和所述第一符号矩阵的第2列中第e组的4个符号,a、b和e互不相等。其中,0≤a<4且4≤e<8,或者,0≤e<4且4≤a<8。

进而,交织器将第二符号矩阵输出至编码器,由编码器对第二符号矩阵中每行12符号共120比特进行内码编码以得到8个码字。在一种可能的实施方式中,采用Hamming(128,120)进行内码编码,内码编码后将得到8×128=1024个比特。在另一种可能的实施方式中,采用BCH(136,120)进行内码编码,内码编码后将得到8×136=1088个比特。
在该应用场景1中,卷积交织器中32条延迟线,最长延迟为3V=3Q×d=408个符号,延迟较短。采用Hamming(128,120)进行内码编码时,每个Hamming信息位总共12个符号。对于客户侧接口为每个通道100Gb/s的1×800G,2×400G,4×200G或8×100G,每个Hamming信息位的12个符号来自于12个不同外码码字符号,使得整体级联FEC方案性能较好。

需要说明的是,延迟器每次输出96个符号写入到交织器缓存中。其中,延迟器输出的来自数据流h(0≤h<32)的3个符号写入交织器缓存中第h行。一种写入方式如下:对延迟器输出的3个符号,来自数据流h的第0个、第1个和第2个符号分别写入交织器缓存中第h行的第0列、第1列和第2列。另一种写入方式如下:对延迟器输出的3个符号,来自数据流h的第0个、第1个和第2个符号分别写入交织器缓存中第h行的第2列、第1列和第0列。
