背景技术
PON(无源光纤网络，Passive Optical Network)是一种典型的无源光纤网络，PON系统通常由局侧的光线路终端(Optical Line Terminal，OLT)、用户侧的光网络单元(Optical Network Unit，ONU)和光分配网络(Optical Distribution Network，ODN)组成。
传统的PON系统中，ONU在将接收的业务发送给OLT时，如果高优先级的业务到达ONU时，ONU正在发送一个低优先级的业务，则需要等待该低优先级的业务发送完毕再发送高优先级的业务。如图1所示，业务1的优先级高于业务2的优先级，业务1到达ONU时，业务2正在发送。此时业务1需要等待业务2发送完毕之后再发送，如图2所示，这种传输方式造成高优先级业务的传输具有一定的时延，时延大小如图1所示，业务2当前未完成发送的数据量越大，业务1的传输时延越大，尤其对于时间敏感的业务来说，直接影响该业务的时效性。

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。此外，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
图3为本申请实施例提供的一种业务传输方法的流程图，本实施例应用于PON系统的业务传输，降低时间敏感业务的传输时延。该方法可以由业务传输装置来执行，该装置可以采用软件和/或硬件的方式实现，并一般集成在发送端中，发送端可以是ONU也可以是OLT，当发送端为ONU时，接收端为OLT，当发送端为OLT时，接收端为ONU，其中ONU到OLT的传输方向称为上行方向，OLT到ONU的传输方向称为下行方向，上行方向和下行方向的业务传输过程类似，实施例以上行方向为例，并应用在同一ONU中。参考图3，该方法如下步骤：
S110、一个传输实体抢占另一个传输实体的传输机会，进行业务传输。
本实施例的业务传输过程可以通过主动方式实现，也可以通过被动方式实现，其中，主动方式是传输实体主动抢占传输机会，进行业务传输，被动方式是传输实体在受控的情况下抢占传输机会，进行业务传输，例如某传输实体在控制器的控制下抢占另一个传输实体的传输机会。实施例以被动方式为例。传输实体是用于将发送端接收的业务传输至接收端的装置。传输机会是传输实体进行业务传输的机会，传输实体在拥有传输机会的情况下 进行业务传输，本实施例中传输实体的传输机会可以通过抢占得到，尤其是在传输TSN(时间敏感网络，Time Sensitive Network)业务时，通过抢占传输机会，可以降低TSN业务的传输时延。
在一些实施例中，可以根据传输实体的标识信息确定该传输实体是否可以被抢占，例如当某传输实体被标识为允许被抢占时，表示该传输实体的所有传输机会均可以被抢占。也可以根据传输机会的标识信息确定该传输机会是否可以被抢占，例如当某传输机会被标识为允许被抢占时，表示该传输机会可以被抢占。一般情况下，还可以根据传输实体的优先级设置传输实体的标识信息，例如高优先级的传输实体可以抢占低优先级的传输实体。
不同优先级的传输实体可以对应不同优先级的业务，业务的优先级可以由用户侧确定，然后通过发送端的对应端口发送给发送端，发送端根据不同的端口获取对应业务的优先级。也可以由发送端确定，例如用户侧将业务以数据包的形式通过同一端口发送给发送端，发送端通过解析数据包确定各业务的优先级。发送端接收业务后可以按照业务的优先级将业务分配给对应的传输实体，由传输实体发送至接收端。具体的分配规则实施例不进行限定，例如可以是高优先级的业务分配给高优先级的传输实体，低优先级的业务分配给低优先级的传输实体。示例性的，在一种情况中，传输实体A被标识为允许抢占，传输实体B被标识为允许被抢占，当传输实体A有高优先级的TSN业务到来时，可以控制传输实体A抢占传输实体B的传输机会，使传输实体A抢先传输高优先级的TSN业务，降低高优先级业务的传输时延。
本申请实施例提供一种业务传输方法，包括：一个传输实体抢占另一个传输实体的传输机会，进行业务传输。相比一些情形，本方案的传输实体通过抢占传输机会实现业务传输，有效降低了业务的传输时延。
图4为本申请实施例提供的另一种业务传输方法的流程图。
S210、配置所述传输机会或传输实体的属性信息。
其中，所述传输机会的属性信息包括所述传输机会的抢占属性，所述传输实体的属性信息包括所述传输实体的优先级属性和/或抢占属性。传输机会的抢占属性由OLT配置，用于标识该传输机会是否允许被抢占。在一种情况中，传输机会可以是带宽，则OLT可以在带宽分配的BWmap中对允许被抢占的带宽进行标识。实施例对带宽的类型不进行限定，例如可以是固定带宽(fix)、保证带宽(Assured)、非保证带宽(non-Assured)和尽力而为带宽(Best-Effort)中的一种或多种。
图5为本申请实施例提供的一种BWmap的结构图。
参考图5，BWmap包括N个分配结构(Allocation structure)，Allocation structure 用于将OLT分配的带宽分配给ONU，每个分配结构包括带宽分配标识(Allocation Identifier，Alloc-ID)域、带宽分配的选项(Flags)域、开始时间(StartTime)域和授予尺寸(Grant Size)域、强制苏醒指示(FWI)域、突发开销参数(Bprofile)域和混合纠错(HEC)域。其中，Flags即带宽分配的选项，占两位比持，一位比特用于指示ONU是否发送上行动态带宽报告(DBRu)，另一位比特用于指示ONU是否发送上行物理层操作、管理和维护(Physical Layer Operations、Administration and Maintenance upstream，简称PLOAMu)消息。StartTime表示ONU发送的XG-PON的传输汇聚突发(XGTC burst)的第一个字节在125us的上行帧中的位置。当ONU接收到一个分配结构时，如果ONU根据带宽分配标识判断此分配结构是分配给自己的，ONU将在该分配结构中的开始时间指示的时刻开始发送带宽分配标识对应的传输容器中的数据，发送的数据长度为ONU根据该分配结构中的授予尺寸解析出的ONU可以发送的数据长度。
在一些实施例中，可以缩减StartTime域和Grant Size域，扩展Flags域，在Flags域中表示该带宽是否允许被抢占，例如将StartTime域和Grant Size域分别由原来的16比特缩减为14比特，在Flags域增加4个比特，在一种标识方式中，当该带宽允许被抢占时，可以将这4个比特取值为1，当该带宽不允许被抢占时，可以将这4个比特取值为0。在另一种标识方式中，可以将这4个比特取值为0，1，2，…，7之一，不同的取值代表其不同的优先级，例如0表示优先级最低，7表示优先级最高，优先级低的可以被优先级高的抢占。当然还可以采用其他的标识方式，实施例不进行限定。
传输实体的优先级属性和抢占属性可以在ONU中配置，其中，优先级属性用于标识传输实体的优先级，在一些实施例中，可以在传输实体的OMCI(发送端管理控制接口，ONU Management and Control Interface，OMCI)的属性中增加一个属性，标识该传输实体的优先级，高优先级的传输实体可以抢占低优先级传输实体的传输机会。传输实体的抢占属性用于标识该传输实体是否允许抢占，在一些实施例中，可以对Alloc-ID进行标识，Alloc-ID用于唯一标识传输实体，也可以在OMCI的属性中增加一个属性，标识该传输实体是否允许抢占，当某传输实体被标识为允许被抢占时，表示该传输实体的所有传输机会均可以被抢占，例如当传输机会为带宽时，表示分配给该传输实体的所有带宽均可以被抢占。
S220、一个传输实体抢占另一个传输实体的传输机会，进行业务传输。
在一些实施例中，传输实体包括传输通道(GEM Port)和传输容器，传输通道用于将发送端接收的业务发送给传输容器，由传输容器发送给接收端。一个发送端可以包含一个或多个传输实体，一个传输实体包含一个传输容器，一个传输容器上可以集成一个或多个传输通道，实施例以一个发送端包含多个传输实体，一个传输容器上集成多个传输通道为 例。不同的传输通道可以具备不同的优先级，不同的传输容器可以具备不同的优先级。传输容器包括上行传输容器和下行传输容器，上行传输容器用于上行方向的业务传输，下行传输容器用于下行方向的业务传输，为便于描述，实施例将上行传输容器称为T-CONT(传输容器，Transmission CONT)，下行传输容器称为切片，并将抢占传输机会的传输实体称为抢占传输实体，被抢占传输机会的传输实体称为被抢占传输实体。
在一种情况中，如果被抢占传输实体当前未传输业务，抢占传输实体抢占所述被抢占传输实体的传输机会，进行业务传输。这种情况可以适用于不同T-CONT之间的抢占。示例性的，当传输实体为T-CONT时，传输机会以带宽为例，抢占T-CONT有业务到来时，如果被抢占T-CONT当前未传输业务，则抢占T-CONT可以直接抢占被抢占T-CONT的带宽，完成自身业务的传输。
在另一种情况中，如果被抢占传输实体当前在传输业务，抢占传输实体在所述被抢占传输实体完成业务传输后，抢占所述被抢占传输实体的传输机会，进行业务传输。示例性的，当传输实体为T-CONT时，如果被抢占T-CONT的传输通道A当前在传输业务，则被抢占T-CONT的传输通道A完成业务传输后，抢占T-CONT抢占被抢占T-CONT的剩余带宽，被抢占T-CONT暂停传输。其中，传输通道A完成业务传输是指传输通道A完成数据包的传输，即当传输通道A在传输某数据包时，抢占T-CONT需要在传输通道A完成当前数据包的传输后再抢占被抢占T-CONT的剩余带宽。
在另一种情况中，如果被抢占传输实体当前在传输业务，抢占传输实体抢占所述被抢占传输实体的传输机会，所述被抢占传输实体暂停当前业务的传输。示例性的，当传输实体为T-CONT时，如果被抢占T-CONT的传输通道A当前在传输业务，则被抢占T-CONT的传输通道A暂停当前业务的传输，抢占T-CONT抢占被抢占T-CONT的剩余带宽，这种情况下的抢占既发生在传输通道之间，又发生在T-CONT之间，可以进一步降低业务的传输时延。当传输实体为传输通道时，如果被抢占传输通道当前在传输业务，则抢占传输通道优先传输业务，被抢占传输通道暂停当前业务的传输，这种情况下的抢占可以发生在同一T-CONT的不同传输通道之间。
S230、抢占结束后，被抢占传输实体继续进行业务传输。
示例性的，当传输实体为传输通道时，如果低优先级传输通道因高优先级传输通道的抢占而被暂停当前业务的传输，则抢占结束后，低优先级传输通道继续传输未完成的业务。当传输实体为T-CONT时，如果被抢占T-CONT当前未传输业务，则抢占结束后，被抢占T-CONT在获取发送机会后行业务传输。
在上述实施例的基础上，还可以更改传输实体的数据获取方式，以允许一个传输实体 抢占另一个传输实体的传输机会。相应的，在一个传输实体抢占另一个传输实体的传输机会，进行业务传输之前，还包括：
传输实体每隔设定时间获取待传输数据分段；
当所述传输实体被抢占时，所述传输实体结束获取待传输数据分段，并发送已经获取的待传输数据分段。
传统的业务传输是以完整数据包的形式传输，即当高优先级的传输实体有业务到达时，如果低优先级的传输实体正在传输一个业务，则高优先级的传输实体需要待低优先级的传输实体在数据包传输结束后才可以传输，导致高优先级的业务具有一定的传输时延。本实施例通过更改传输实体的数据获取方式支持各传输实体之间的抢占。在一些实施例中，可以使传输实体每隔设定时间获取待传输数据分段，当高优先级的传输实体有数据到达时，可以随时抢占低优先级传输实体的传输机会抢先发送，降低传输时延。其中，时间间隔可以保持不变，例如每隔固定时间间隔获取一次待传输数据分段，也可以随机变化或按照一定规律变化，实施例对时间间隔不进行具体限定。待传输数据分段的大小也是类似。在一种情况中，传输容器可以理解为一组传输通道，传输容器的数据获取方式更改之后，传输容器下的传输通道的数据获取方式也相应更改，而且更改方式相同。
图6为本申请实施例提供的另一种业务传输方法的流程图。
S310、一个传输实体抢占另一个传输实体的传输机会，进行业务传输。
S320、向接收端发送抢占指示信息，以使所述接收端根据所述抢占指示信息补偿被抢占传输实体或缓存被抢占的业务。
抢占提示信息用于指示接收端补偿被抢占传输实体或缓存被抢占的业务。在一些实施例中，抢占提示信息可以添加在XGTC burst的XGTC header中，参考图7，图7为本申请实施例提供的一种XGTC header的结构图，XGTC header包括ONU-ID域(10bits)、Ind域(9bits)、HEC域(13bits)以及PLOAMu域(0 or 48bits)，ONU-ID用于唯一标识ONU。在一些实施例中，可以通过Ind域标识是否发生了抢占，在一种方式中，可以通过标识bit7来表示是否发生抢占，例如当bit7为1时表示发生了T-CONT带宽抢占，当bit7为0时表示未发生T-CONT带宽抢占。当接收端检测到bit7为1时，可以根据被抢占T-CONT的标识对被抢占T-CONT进行带宽补偿，保证该T-CONT的传输性能。
在一些实施例中，抢占提示信息还可以添加在XGEM header中，参考图8，图8为本申请实施例提供的一种XGEM header的结构图，XGEM header包括PLI域(14bits)、Keyindex(2bits)、XGEM port-ID域(16bits)、Options域(18bits)、LF域(1bit)以及HEC域(13bits)，XGEM port-ID用于唯一标识T-CONT的传输通道，在一种方式中，可以利用 Options域的最后一个比特标识该传输通道是否发生抢占，例如为1表示发生了抢占，为0表示未发生抢占。当接收端检测到Options域的最后一个比特为1时，缓存该传输通道对应的业务，以备后续数据包剩余部分到达后进行重组得到完整的数据包。
在上述实施例的基础上，该方法在配置所述传输机会或传输实体的属性信息之后，还包括：
允许被抢占的传输实体接收光线路终端分配的传输机会。
传输机会以带宽为例，在确定允许抢占传输实体和允许被抢占传输实体之后，OLT可以给允许被抢占传输实体继续分配剩余的带宽，避免该传输实体因带宽被抢占而影响后续传输性能。
在上述实施例的基础上，所述配置所述传输实体的属性信息，包括：
配置专门用于被抢占的传输实体。
传输机会以带宽为例，在一种方式中，可以将某个允许被抢占的T-CONT配置为专用T-CONT，专用T-CONT不与具体业务挂钩，即专用T-CONT的带宽仅供其他T-CONT的抢占。
在上述实施例的基础上，该方法还包括：
当多个传输实体抢占同一个传输机会且出现冲突时，所述传输机会对应的被抢占传输实体接收光线路终端分配的传输机会，或者抢占传输实体接收光线路终端分配的传输机会。
本实施例提供的业务传输方法除了可以应用于同一发送端，还可以应用于不同发送端，各传输实体之间的抢占不仅可以主动执行也可以被动执行。当应用在不同发送端且主动执行时，如果多个传输实体抢占同一个传输机会且出现冲突，为了消除抢占冲突，在一种方式中，可以给传输机会对应的被抢占传输实体继续分配传输机会，在另一种方式中，还可以给抢占传输实体单独分配传输机会。
以发送端为ONU，业务传输方法应用在不同ONU之间为例，当多个ONU抢占同一传输机会且发生冲突时，OLT可以继续为被抢占传输实体分配传输机会，或者为抢占传输实体单独分配传输机会。

第一控制模块41，用于控制一个传输实体抢占另一个传输实体的传输机会，进行业务传输。
