具体实施方式
为了使本申请的目的、技术方法及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
目前FTTx市场部署了大量具有千兆位功能的无源光纤网络(Gigabit-Capable Passive Optical Network，GPON)系统，随着标准升级和用户需求增加，GPON系统开始逐步向XG(S)-PON升级演进。GPON和XG(S)-PON采用波分方式共存，即GPON和XG(S)-PON的下行波长不一样，上行波长也不一样。在升级演进过程中，GPON和XG(S)-PON可能会在同一个ODN中同时共存，即同一个ODN中既有GPON系统也有XG(S)-PON系统，为了降低XG(S)-PON系统对GPON系统的影响，ITU-T标准G.987.2and G.9807.1定义了XG(S)-PON ONU光发射模块SMSR为30dB，以限制其引起的模分配噪声(Mode Partition Noise，MPN)。
但是在实际测试中，还是存在XG(S)-PON ONU影响GPON OLT接收灵敏度从而导致误码的情况，特别是当GPON ONU到GPON OLT的传输损耗较大，而XG(S)-PON ONU到XG(S)-PON OLT的传输损耗较小时。标准组织提出要对XG(S)-PON ONU的OOB PSD进行限定，经过调研，这需要增加XG(S)-PON ONU的成本，由于ONU侧数量大，总体成本较高。
除了XG(S)-PON ONU对GPON OLT有影响，GPON ONU对XG(S)-PON OLT也可能有影响，由于GPON ONU已经大量部署，如果要降低GPON ONU的OOB PSD，总体成本更高。
提高OLT侧接收灵敏度有助于解决该问题，但是提高接收灵敏度难度较大，特别是考虑class D等接收灵敏度本来就很高的情况。
除了XG(S)-PON和GPON之间的影响，TWDM-PON的各个通道之间也存在类似的影响。ITU-T G.989.2标准定了ONU侧的OOB PSD，但目前TWDM-PON暂未大规模部署，如果后续市场有可能大规模部署TWDM-PON，ONU侧实现OOB PSD同样总体成本较高。
不同通道之间的OOB干扰影响，是无源光网络通过不同波长共存于一个ODN的通性问题，如何提供低成本且高效地降低不同通道之间的OOB干扰是亟待解决的问题。
为了解决上述问题，本申请提供了一种带宽分配方法及其装置、计算机存储介质、计算机程序产品。其中一个实施例的带宽分配方法包括：对不同传输通道中的指定分配对象进行带宽分配，使得不同的指定分配对象所获得的带宽符合预设带宽分配条件；其中，预设带宽分配条件包括：不同的指定分配对象所获得的带宽属于彼此不重叠、部分重叠或完全重叠中的任意一种情况。在该实施例中，通过对不同传输通道中的指定分配对象进行带宽分配，使得不同的指定分配对象所获得的带宽符合预设带宽分配条件，其中，预设带宽分配条件可以根据实际网络条件设置为带宽属于彼此不重叠、部分重叠或完全重叠中的任意一种情况，因此，本申请实施例能够对指定分配对象的带宽进行主动分配，从而能够提升带宽分配管理的效率，并且在指定分配对象的带宽分配为彼此存在重叠的情况下，能够测试指定分配对象之间是否存在传输冲突，在指定分配对象的带宽分配为彼此存在不重叠的情况下，能够对指定分配对象之间进行隔离以降低或者消除彼此的影响，从而可以弥补相关方法中的技术空白。
下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的带宽分配方法的流程图。
在图1的示例中，该带宽分配方法包括但不限于步骤S110至S120。
步骤S110：确定不同传输通道中的指定分配对象。
本步骤中，通过预先确定好不同传输通道中的指定分配对象，以便于在后续步骤中对不同传输通道中的指定分配对象进行带宽分配。
需要说明的是，本实施例中的指定分配对象可以但不限于为ONU，该ONU也可以用ONU-ID、PLID、SN、MAC等ONU标识进行表示，或者，也可以是ONU中的逻辑链路，例如逻辑链路标记(Logical Link Identifier，LLID)等，或者带宽分配实体，例如T-CONT、GLID等。
需要说明的是，当步骤S110应用在无源光网络中，不同传输通道的类型可以为多种，应用场景也可以为多种，此处不作限定。例如，随着网络标准升级和用户需求增加，目前的GPON逐步向XG(S)-PON系统演进。在升级演进过程中，GPON和XG(S)-PON可能会在同一个ODN中同时共存，即同一个ODN中既有GPON也有XG(S)-PON，可能存在XG(S)-PON的ONU影响GPON的OLT的接收灵敏度从而导致出现误码的情况，也可能存在GPON的ONU对XG(S)-PON的OLT的接收灵敏度造成影响从而导致出现误码的情况，也就是说，在这种应用场景下的不同传输通道之间存在带外干扰问题，不同传输通道包括XG(S)-PON的传输通道和GPON的传输通道，对应的应用场景为G-PON向XG(S)-PON升级演进过程的共存系统/装置；或者，包括G-PON的传输通道和50G-PON的传输通道，对应的应用场景为G-PON向50G-PON升级演进过程的共存系统/装置；或者，包括XG(S)-PON和50G-PON的传输通道，对应的应用场景为XG(S)-PON向50G-PON升级 演进过程的共存系统/装置中。又如，包括时分复用无源光网络(Time and Wavelength Division Multiplexed PON，TWDM-PON)的不同传输通道等。
需要说明的是，不同的传输通道之间支持时间同步，通过不同的传输通道的支持时间同步的特性，以便于根据其检测不同的传输通道的指定分配对象之间的重叠关系，此处不作详述，在下面各实施例中再仔细说明。
步骤S120：对不同传输通道中的指定分配对象进行带宽分配，使得不同的指定分配对象所获得的带宽符合预设带宽分配条件。
需要说明的是，预设带宽分配条件包括：不同的指定分配对象所获得的带宽属于彼此不重叠、部分重叠或完全重叠中的任意一种情况，其中，“不重叠”指的是不同的指定分配对象的任何一处带宽都不相同，“部分重叠”指的是不同的指定分配对象存在相同的带宽部分但并不完全相同，“完全重叠”指的是不同的指定分配对象的带宽完全相同。
本步骤中，由于在步骤S110中已经确定不同传输通道中的指定分配对象，因此在步骤S120中可以对不同传输通道中的指定分配对象进行带宽分配，使得不同的指定分配对象所获得的带宽符合预设带宽分配条件，其中，预设带宽分配条件可以根据实际网络条件设置为带宽属于彼此不重叠、部分重叠或完全重叠中的任意一种情况，因此，本申请实施例能够对指定分配对象的带宽进行主动分配，从而能够提升带宽分配管理的效率，并且在指定分配对象的带宽分配为彼此存在重叠的情况下，能够测试指定分配对象之间是否存在传输冲突，在指定分配对象的带宽分配为彼此存在不重叠的情况下，能够对指定分配对象之间进行隔离以降低或者消除彼此的影响，从而可以弥补相关方法中的技术空白。
需要说明的是，预设带宽分配条件的设置，可以有不同的实施方式，此处不作具体限定。例如，预先设置好预设带宽分配条件，当确定不同传输通道中的指定分配对象就可以根据预设带宽分配条件对不同传输通道中的指定分配对象进行带宽分配；又如，实时监测不同传输通道中的各个待分配对象的应用情况，此时再对应设置好相应的预设带宽分配条件。
需要说明的是，不同的指定分配对象所获得的带宽属于彼此不重叠、部分重叠或完全重叠中的任意一种情况，并不作为对于预设带宽分配条件的限制，本领域技术人员可以理解地是，在实际应用场景下，可以根据网络情况等因素确定为不同的指定分配对象所分配的带宽到底为哪一种情况，也不排除可能需要分配的带宽为上述三种情况之外的带宽，此处并未限制。为了更好地说明步骤S110至S120的工作原理及流程，以下将逐步给出具体实施例以对步骤S110至S120进行说明。
本申请的一个实施例，对步骤S120进行进一步的说明，步骤S120可以包括但不限于步骤S121。
步骤S121：由OLT根据接收到的测距结果、接收到的光功率或确定的信号冲突情况中的至少一种对不同传输通道中的指定分配对象进行带宽分配。
本步骤中，由于OLT具有接收测距结果、接收光功率以及确定信号冲突情况的功能。因此OLT可以根据接收到的测距结果、接收到的光功率或确定的信号冲突情况中的至少一种对不同传输通道中的指定分配对象进行带宽分配以提升带宽分配管理的效率，也就是说，在具体应用场景中，OLT进行带宽分配的具体实施方式可以为多种，以下将逐步给出具体实施例进行说明。
需要说明的是，测距结果可以但不限于为ONU相对于OLT测距结果，测距方式可以由本领域技术人员根据目前已熟知的技术进行测量，在此不再赘述。
需要说明的是，光功率可以但不限于为ONU的光功率，测量ONU的光功率可以由本领域技术人员根据目前已熟知的技术进行测量，在此不再赘述。
需要说明的是，信号冲突情况可以用于衡量不同的指定分配对象的带宽重叠情况，所以OLT通过所确定的信号冲突情况能够评估不同的指定分配对象的带宽情况，以便于基于该带宽情况对不同传输通道中的指定分配对象进行带宽分配。
本申请的一个实施例，在步骤S121的基础上进行进一步的说明，本申请方法还包括但不限于步骤S130。
步骤S130：响应于对带宽分配结果的获取，OLT向网络管理系统发送带宽分配结果，使得网络管理系统根据带宽分配结果判断带宽分配结果是否符合预设带宽分配要求，或者，使得网络管理系统显示带宽分配结果。
本步骤中，在OLT获取带宽分配结果的情况下，通过OLT向网络管理系统发送带宽分配结果，使得网络管理系统根据带宽分配结果判断带宽分配结果是否符合预设带宽分配要求，以验证带宽分配结果的准确性，防止出现带宽分配不匹配的问题，或者，网络管理系统显示带宽分配结果以向操作人员提示当前场景下的带宽分配已经完成，也就是说，通过OLT向网络管理系统发送带宽分配结果，可以对带宽分配结果进行进一步地确认或者将带宽分配结果进行进一步地可视化呈现以符合带宽分配需求。
需要说明的是，网络管理系统可以为多种，在此不作限制。例如，网络管理系统可以但不限于本领域技术人员所熟知的各种类型的网络管理系统等；又如，也可以为在具体应用场景下相应适配的网络管理系统等。
本申请的一个实施例，对步骤S120进行进一步的说明，步骤S120可以包括但不限于步骤S122。
步骤S122：由网络管理系统对不同传输通道中的指定分配对象进行带宽分配。
本步骤中，由于网络管理系统高度集成化且性能稳定，所以以网络管理系统作为一个协调实体，对不同传输通道中的指定分配对象进行带宽分配，以便于得到对不同传输通道中的指定分配对象而适配的带宽分配结果。
在一可行的实施方式中，网络管理系统相对于OLT单独设置，例如将网络管理系统和OLT设置在两个单独的机房或装置内，网络管理系统作为协调带宽分配的实体，能够生成对不同传输通道中的指定分配对象进行带宽分配的分配指令，例如，该分配指令可以为：对其中一个ONU(记为ONU1)分配相应的带宽，对另一个ONU(ONU2)不分配带宽，进而网络管理系统将该分配指令发送给OLT，然后OLT再根据该分配指令为ONU1和ONU2进行相应的带宽分配。
在另一可行的实施方式中，网络管理系统与OLT相配合设置，例如将网络管理系统和OLT设置在一个整体化的机房或装置内，网络管理系统和OLT结合作为协调带宽分配的实体，网络管理系统能够生成对不同传输通道中的指定分配对象进行带宽分配的分配指令，例如，该分配指令可以为：对其中一个ONU(记为ONU1)分配相应的带宽，对另一个ONU(ONU2)不分配带宽，进而网络管理系统将该分配指令发送给OLT，然后OLT再根据该分配指令为ONU1和ONU2进行相应的带宽分配。
在另一可行的实施方式中，各个传输通道上设置有相应的带宽分配节点，例如ONU1上设置有带宽分配节点1，ONU2上设置有带宽分配节点2；网络管理系统、OLT以及各个传输通道上的带宽分配节点相配合设置，例如将网络管理系统、OLT以及各个传输通道上的带宽分配节点设置在一个整体化的机房或装置内，网络管理系统、OLT以及各个传输通道上的带宽分配节点结合作为协调带宽分配的实体，网络管理系统能够生成对不同传输通道中的指定分配对象进行带宽分配的分配指令，例如，该分配指令可以为：对其中一个ONU(记为ONU1)分配相应的带宽，对另一个ONU(ONU2)不分配带宽，进而网络管理系统将该分配指令发送给OLT，然后OLT再将该分配指令分别发送给各个传输通道上的带宽分配节点，以使得各个传输通道上的带宽分配节点分别进行带宽分配，例如，带宽分配节点1为ONU1分配相应的带宽，带宽分配节点2为ONU2不分配带宽。

本步骤中，对不同传输通道中的指定分配对象进行带宽分配，使得不同的指定分配对象所获得的带宽符合预设带宽分配条件，由于预设带宽分配条件可以根据适配于预设周期而进行配置，所以，在对不同传输通道中的指定分配对象进行带宽分配时，能够使得不同的指定分配对象所获得的带宽在预设周期内符合预设带宽分配条件，达到提升带宽分配管理的效率的目的，并且在指定分配对象的带宽分配为彼此存在重叠的情况下，能够测试指定分配对象之间是否存在传输冲突，在指定分配对象的带宽分配为彼此存在不重叠的情况下，能够对指定分配对象之间进行隔离以降低或者消除彼此的影响，从而可以弥补相关方法中的技术空白。
需要说明的是，预设周期的设置，可以有不同的实施方式，此处不作具体限定。例如，预先确定好一个周期作为预设周期，考虑该预设周期而进行带宽分配；又如，预先统计不同传输通道中的指定分配对象的相关历史周期(例如1天、1个月、1个季度等)的数据，从而根据相关历史周期的数据确定得到预设周期，再考虑该预设周期而进行带宽分配。
在一可行的实施方式中，在不同的指定分配对象所获得的带宽属于彼此不重叠的情况下，预设带宽分配条件还包括：
不同的指定分配对象所获得的带宽在时序上相互错开。
需要说明的是，由于不同的指定分配对象所获得的带宽属于彼此不重叠，也就是说，不同传输通道中的指定分配对象互相不会产生影响，因此可以将该不同传输通道中的指定分配对象的带宽设置为在时序上相互错开，从而能够提升带宽分配管理的效率。

需要说明的是，由于不同的指定分配对象所获得的带宽属于部分重叠且重叠的部分小于第一阈值的情况，也就是说，不同传输通道中的指定分配对象互相会产生影响，但重叠部分不算多，也就是说重叠部分属于相对小的范围，因此在由于带宽存在部分重叠而导致的小范围、影响相对较小的传输冲突的情况下，无需借助于外部或者其余依仗，OLT自身可以支持对该传输冲突进行纠错处理，从而能够提升带宽分配管理的效率。
需要说明的是，第一阈值可以为本领域技术人员根据实际场景而相应设置的，此处不作限制。例如，预先确定好一个参数作为第一阈值，考虑该第一阈值而进行预设带宽分配条件的设置；又如，预先统计不同传输通道中的指定分配对象的历史带宽的数据，从而根据相关历史带宽的数据设置相关的第一阈值。

步骤S160：对不同的指定分配对象进行冲突检测以判断不同的指定分配对象之间是否存在传输冲突。
本步骤中，由于不同的指定分配对象所获得的带宽属于部分重叠且重叠的部分大于第二阈值的情况， 也就是说，不同传输通道中的指定分配对象互相会产生影响，且重叠部分相对较多，也就是说重叠部分属于相对大的范围，因此由于带宽存在部分重叠而导致传输冲突的情形将会更加复杂，所以，通过对不同的指定分配对象进行冲突检测，可以判断不同的指定分配对象之间是否存在传输冲突，以便于在后续步骤中根据是否存在传输冲突而选择性地对存在传输冲突的不同的指定分配对象进行进一步地带宽分配。
在一可行的实施方式中，第二阈值不小于上述实施例所示的第一阈值，根据第一阈值和第二阈值可以组合判断不同的指定分配对象的带宽的重叠程度，以便于更准确地评估不同的指定分配对象之间的互相影响程度。

步骤S170：对不同的指定分配对象进行冲突检测以判断不同的指定分配对象之间是否存在传输冲突。
本步骤中，由于不同的指定分配对象所获得的带宽属于完全重叠的情况，也就是说，不同传输通道中的指定分配对象必然会产生影响，因此由于带宽存在完全重叠而导致传输冲突的情形将会更加复杂，所以，通过对不同的指定分配对象进行冲突检测，可以判断不同的指定分配对象之间是否存在传输冲突，以便于在后续步骤中根据是否存在传输冲突而选择性地对存在传输冲突的不同的指定分配对象进行进一步地带宽分配。

判断不同通道上的ONU之间存在潜在冲突，通过系统之外手段获取。例如，在安装、运维过程中，获知哪些ONU的分支较短，哪些ONU的分支较长，如果不同通道上的ONU分支差别较大，可以将这些ONU列为存在潜在影响的ONU。再如，在故障诊断过程中，发现或者怀疑哪些不同通道上的ONU之间彼此有影响，将这些ONU列为存在潜在影响的ONU。

在另一可行的实施方式中，带宽分配结果由网络管理系统对不同传输通道中的指定分配对象进行带宽分配而得到，也就是说，由于网络管理系统高度集成化且性能稳定，所以以网络管理系统作为一个协调实体，对不同传输通道中的指定分配对象进行带宽分配，以便于得到对不同传输通道中的指定分配对象而适配的带宽分配结果。

步骤S220：根据带宽分配结果在不同的指定分配对象中确定多个目标对象。
本步骤中，由于步骤S210中已经获取得到指定分配对象所获得的带宽分配结果，所以在步骤S220中可以根据带宽分配结果在不同的指定分配对象中确定多个目标对象，以便于在后续步骤中对多个目标对象进行故障诊断处理。

本步骤中，当不同的指定分配对象存在带宽之间出现重叠的情况，则说明相关的指定分配对象的带宽出现重合，可能产生较大的相互影响，所以，在这种情景下，根据带宽分配结果在不同的指定分配对象中，能够准确地确定这部分的带宽之间存在重叠的多个指定分配对象为多个目标对象，以便于在后续步骤中对所确定的多个目标对象进行故障诊断处理。
步骤S230：对多个目标对象进行故障诊断处理。
本步骤中，由于步骤S220中已经确定了多个目标对象，因此步骤S230中可以通过对多个目标对象进行故障诊断处理，使得多个目标对象能够获得的符合预设带宽分配条件的带宽，也就是说，通过对多个目标对象进行故障诊断处理，使得对不同传输通道中的多个目标对象能够进行进一步地带宽分配，解决多个目标对象出现的带宽分配问题，提升带宽分配管理的效率，并且在指定多个目标对象的带宽分配为彼此存在重叠的情况下，能够测试指定分配对象之间是否存在传输冲突，在指定多个目标对象的带宽分配为彼此存在不重叠的情况下，能够对多个目标对象之间进行隔离以降低或者消除彼此的影响，从而可以弥补相关方法中的技术空白。

步骤S234：当多个目标对象中存在导致出现误码的指定分配对象，并且光线路终端支持对误码的纠错处理，确定多个目标对象之间不存在传输冲突。
本步骤中，当多个目标对象中存在导致出现误码的指定分配对象，则说明多个目标对象之间的带宽存在相互影响的情况，也就是说，基于带宽影响可能造成误码问题，并且光线路终端支持对误码的纠错处理，也就是说，多个目标对象之间的带宽相互影响的程度不大，基于光线路终端即可支持对误码的纠错处理，所以可以确定多个目标对象之间不存在传输冲突，也就无需对多个目标对象进行传输冲突的处理。
下面给出具体示例二以进行说明本申请实施例提供的带宽分配方法的处理流程。
示例二：
协调带宽分配方面，用于分析不同传输通道上的带宽分配，检查不同传输通道上的ONU带宽分配之间的重叠情况，并结合OLT侧的冲突影响分析，诊断不同传输通道上的ONU之间是否存在冲突影响。
具体地，可以检查不同传输通道的哪些ONU带宽分配存在重叠，但是彼此未出现影响或者严重影响，未出现影响是指彼此互相没有影响，OLT侧未出现接收误码，未出现严重影响是指彼此有影响，例如OLT侧出现接收误码，但是OLT侧能够把误码纠正过来。
可以分析这些带宽分配结果，检查不同通道上哪些ONU的带宽分配之间存在重叠，彼此存在影响，可以用于定位问题，定位到问题后可以采取规避措施，例如可以更换ONU，或者更改ODN分支以消除问题。
协调带宽分配要求不同传输通道上的带宽分配结果以可以识别出时序关系，以判断不同传输通道上的ONU带宽分配之间是否存在重叠关系，可以通过时间同步来实现。协调带宽分配中不同通道的带宽分配可以是独立的，彼此不存在交互(除了时序关系识别所需功能外)，也可以是集成在一起的。
为了更加清楚的说明本申请实施例提供的带宽分配方法的处理流程，下面结合具体应用场景给出不同的具体示例以进行说明。
示例三：
通过网络管理系统等外部系统在协调带宽分配中设置不同传输通道中彼此没有重叠的带宽，使得不同传输通道中存在潜在冲突的ONU带宽分配在时序上错开，从而避免彼此存在影响。
判断不同通道上的ONU之间存在潜在冲突，通过系统之外手段获取。例如，在安装、运维过程中，获知哪些ONU的分支较短，哪些ONU的分支较长，如果不同通道上的ONU分支差别较大，可以将这些ONU列为存在潜在影响的ONU。再如，在故障诊断过程中，发现或者怀疑哪些不同通道上的ONU之间彼此有影响，将这些ONU列为存在潜在影响的ONU。
示例四：
利用测距结果比较判断，不同传输通道中测距结果相差较大的ONU，例如测距结果反应的逻辑距离差别大于15公里，在协调带宽分配中把它们的带宽错开，彼此不重叠。当然，测距结果的差值门限可以根据具体情况进行设置，如果要求严格一些，可以将该值设置小一些，如果希望放松一些，可以将该值设置大一些。
ONU一般都会进行测距，OLT对各传输通道ONU的测距结果进行比较，如果不同传输通道中ONU的测距结果或者对应逻辑距离相差较大，则通过协调带宽分配，错开这些ONU的带宽分配。
示例五：
利用OLT侧接收光功率，不同传输通道中OLT接收光功率相差较大的ONU，例如接收光功率相差15dB 以上，在协调带宽分配中把它们的带宽错开，彼此不重叠。当然接收光功率的差值门限可以根据具体情况进行设置，如果要求严格一些，可以将该值设置小一些，如果希望放松一些，可以将该值改制设置大一些。
OLT测试不同传输通道中ONU的接收光功率并进行比较，接收光功率相差较大不同传输通道中的ONU，在协调带宽分配中把它们的带宽分配错开。
示例六：
通过示例三、示例四、示例五判断不同通道中的ONU彼此可能存在影响，有可能不是非常准确，因此可能需要在协调带宽分配中设置很多可能存在影响但实际没有影响的ONU带宽分配。
本示例中，可以将不同传输通道中可能存在影响的ONU，让它们在互相重叠的带宽内发送测试信号，OLT通过检测判断它们之间是否存在影响，如果OLT侧未发现明显的误码增量，则认为它们之间存在影响，否则认为它们之间不存在影响。当然，为了提高准确性，可以通过多次重复测试后再判断是否存在影响。
通过动态测试，OLT获取不同传输通道中存在影响的ONU，将它们的带宽分配错开。如果需要，可以对这些ONU继续进行动态测试。
示例七：
