具体实施方式
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)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。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。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。
下面将结合附图，对本申请中的技术方案进行描述。
本申请的数据转发方法可以应用于光纤通信系统。图1为一种光纤通信系统的示意图。参阅图1，光纤通信系统可以包括用户终端10、光网络终端(optical network terminal，ONT)20、光线路终端(optical line terminal，OLT)30和宽带网络网关(broadband network gateway，BNG)40和业务服务器50等。需要说明的是，图1只是一个例子，有些网络中OLT30和服务器50之间是可以不设置BNG 40。
OLT 30又可以称为局端设备，其可以统一管理多个ONT 20。OLT 30可以充当ONT 20与上层网络(即汇聚层)之间的媒介，将从上层网络接收到的数据作为下行数据转发到ONT 20，以及将从ONT 20接收到的上行数据转发到上层网络。OLT 30通过光分配网络(图中未示出)以点到多点的形式连接到多个ONT 20。
ONT 20可以分布式地设置在用户侧位置(比如用户驻地)。ONT 20可以为用于与OLT 30和用户进行通信的网络设备，其可以为用户提供宽带语音、数据或视频等业务。具体而言，ONT 20可以充当OLT 30与用户终端10之间的媒介。在上行方向上，用户终端10 向ONT 20发送信息，例如业务信息或用户信息。ONT 20将上述信息发送给OLT 30，OLT 30将上述信息按照业务类型进行分类，然后通过BNG 40分别送入各种业务服务器50。业务服务器50可以提供一种或多种业务，例如视频业务、音频业务、实时通信业务、批量传输业务等。在下行方向上，OLT 30将各种业务数据汇聚后，对业务数据进行调度后发送至ONT 20，ONT 20将发送给用户终端10。需要说明，光网络终端ONT在部分场景下也被称为光网络单元(optical network unit，ONU)，因此在本申请文件提供的方案中，光网络单元和光网络终端这两个概念可以互换。
除了对业务数据进行汇聚和转发之外，OLT还可以实现基于设备的网元管理和基于业务的安全管理和配置管理。不仅可以监测、管理设备及端口，还可以进行业务开通和用户状态监测，而且还能够针对不同用户的服务质量(quality of service，QoS)或服务等级协议(service level agreement，SLA)参数要求进行带宽分配，以及对ONT进行管理和测距等；其中实际网络参数不会高于用户开通的SLA参数。为了区分概念，这里将用户开通业务时，业务提供商或宽带提供商对其承诺的SLA参数称为承诺SLA参数，网络中实际使用的SLA参数称为实际SLA参数，实际SLA参数一般不会超过承诺SLA参数，下文中除非有限定说明，SLA参数或SLA参数一般是指实际SLA参数。在业务提供过程中实际SLA参数可能一直不变，也可能变化，如果变化，其业务开始时的实际SLA参数也称为初始SLA参数。除了OLT 30进行带宽控制之外，BNG 40也可以用于带宽控制。用户终端10也可以称为终端设备、终端、用户设备、电子设备等。用户终端10具体可以是数字电视、个人电脑、手机、平板电脑、虚拟现实(virtual reality，VR)设备等。
用户终端10通过上下行数据通道与业务服务器50进行通信，由于用户终端10需传输的用户的不同业务数据对数据通道的性能有不同的要求，如果不进行区分，在同一个通道上传输，可能满足不了部分业务的传输质量需求或者造成资源浪费。比如，某一用户的数据中，第一种业务数据要求时延小于20毫秒，而第二种业务数据要求时延小于80毫秒，但这两种数据均通过相同的数据通道传输，如果该数据通道只能满足小于80毫秒指标，那么第一种业务就达不到需求；反之，如果该数据通道只能满足小于20毫秒指标，那第二种业务数据在该数据通道传输就比较浪费，该数据通道没有被充分利用。以视频业务为例，视频业务包括VR业务、高清视频直播业务和交互式网络电视(IPTV)业务等子类业务。与IPTV业务相比，VR业务要求更低时延。按照上述方法将VR业务流量和IPTV业务流量一起进行调度，如果基于就低原则，此时只满足了IPTV的服务质量要求，难以满足VR业务的服务质量要求(例如时延要求)。同理，将高清视频直播业务流量和IPTV业务流量一起进行调度，也难以满足高清视频直播业务的时延要求。如果基于就高原则，按照最高时延需求进行调度，网络资源就不能得到充分利用。
因此，业务切片技术被提出来。切片也称为网络切片，每个网络切片上具有相同或相似的业务类型或业务指标需求。比如可以为虚拟现实业务创建网络切片，也可以为高清视频直播业务创建网络切片，然后根据创建的网络切片分配对应的传输资源和配置参数。这样用户流量按照不同的业务以更小的粒度进行了区分，分别匹配各自的传输资源和配置参数进行传输以达到各自的业务指标需求，但如何为分片的业务配置精准的配置参数一直是难点。
本发明实施例提供一种业务切片处理方法，可以用于OLT设备，能够为分片的业务
获取到精准配置参数，然后发送给ONT进行配置以提供更好的业务服务。如图2所示，
该数据传输方法可以包括：
步骤201：OLT对接收到的数据报文进行业务识别，确定所述数据报文对应第一业务；其中所述数据报文基于初始的第一SLA参数进行传输；
作为一种可选实施例，可以通过数据报文中的业务标识来识别所述数据报文所属于的业务类型(以下简称目标业务)；也可以通过可以根据数据报文中包含的五元组信息中的一项或多项判断下行报文是否属于哪种目标业务。五元组信息包括：源网际互连协议(Internet Protocol，IP)地址、源端口、目的IP地址、目的端口和传输层协议。例如，在OLT上存储有具体业务(比如视频业务)的服务器IP地址列表，当下行数据报文的源IP地址为目标业务的服务器IP地址时，确定下行数据报文属于目标业务报文。在另一个例子中，在OLT上存储有与目标业务对应的协议标识。当下行数据报文携带有该协议标识时，确定下行数据报文属于目标业务报文。类似的，上行数据方向上的数据报文也可以用同样的方法识别。
步骤202：收集对所述第一业务的至少一个质量评估参数；
其中所述质量评估参数是反映业务在终端侧呈现构成过程中服务质量的参数，可以是业务传输路径上的关键执行指标(Key Performance Indicator，KPI)数据，包括反映网络设备服务能力的设备KPI、反映网络路径质量的网络KPI和反映在终端侧的业务运营质量的用户KPI。作为一种可选实施例，可以收集下列中的至少一项：收集用户在某一段时间内对该业务的服务体验的反馈信息；汇总终端主动上报的业务质量数据，比如卡顿次数；也可以汇总网络质量数据，比如丢包率、信噪比等。
步骤203：根据所述收集到的质量评估参数，对所述初始的第一SLA参数进行修正；将所述修正后的第一SLA参数和所述第一业务进行关联；
具体地，OLT根据收集到的至少一个质量评估参数来反向调整业务的SLA参数。比如对于一个视频业务，收集到的质量评估参数显示时延大、丢包严重；说明当前的SLA参数并不能很好地保证视频业务的开展，所以需要修正当前SLA参数，可以增大SLA参数中的带宽大小和/或增大重传比例；对于一个游戏业务，收集到的质量评估参数显示时延为10ms，但游戏业务流畅运行只需50m以内即可，这时可以修正当前SLA参数，可以将SLA参数中的带宽进行降低。可以通过修正后再收集质量评估参数，并根据质量评估系数再次修正；通过多次迭代以达到最适合目标业务的SLA参数。到该步骤结束，所述OLT完成了用户业务的质量评估，确定了需要修正的第一SLA参数值。
进一步地，该方法还包括：步骤204：所述OLT将所述修正后的第一SLA参数发送给ONT，使所述ONT基于所述修正后的第一SLA参数发送和/或接收所述第一业务的数据。
其中，ONT就可以修正后的第一SLA参数为基准，以SLA参数变化的方向调整相应的参数。其中可选的，所述OLT根据所述修正后的第一SLA参数调整本地的参数。进一步地，所述OLT还可以将与修正后的第一SLA参数关联的具体QoS参数模板发送给ONT。
本方法实施例通过对流量数据中的各种数据报文所归属的业务进行识别后，对业务分片的SLA参数根据收集到的质量评估参数进行修正，OLT和/或ONT进行对应网络参数 的重配置，从而达到修正后的SLA参数更贴合实际的业务切片传输需求，优化终端配置和合理分配网络资源，这样既能避免资源浪费又能保证业务正常开展。进一步地，业务提供商或者宽带运营商可以根据一个用户多周期的实际SLA参数数据，确定该用户的宽带需求区间，对该用户的消费套餐进行合理建议；或者根据多用户的实际SLA参数数据，确定现有网络中的设备容量是否足够，来对未来的网络进行合理规划，以及对设置更合理的承诺SLA参数数据。
以上是OLT对单一业务从最优网络资源利用率的角度对其SLA参数进行修改的，但OLT上一般都会有多种业务数据。由于OLT设备有最大能力限制，如果所有业务都保证最好的传输指标，可能超过了OLT能力的天花板；或者虽然在OLT理论能力内，但由于网络质量差，实际提供的能力不够。这时就不能只单独考虑某一业务，而需要将多种业务整体考虑。
所以，所述业务切片处理方法还可以进一步包括，步骤205：所述OLT确定其他数据报文属于第二业务，并且根据收集的对所述第二业务的至少一个质量评估参数，对发送第二业务的初始第二SLA参数也进行修正得到修正后的第二SLA参数；
步骤206：根据所述网络容量或业务优先级中的至少一个，调整所述修正后的第一SLA参数和修正后的第二SLA参数中至少一个，保证总的能力需求不超过所述OLT的设备能力。
需要说明的是，上文虽然只提到了第一业务和第二业务，但并不限定OLT上只有两种业务流收发的情况。OLT上有不只有两种业务流时，步骤205种的第二业务就是一个合集概念，包含第一业务外的所有业务，第二SLA参数包含第一业务外的所有业务各自对应的SLA参数。其中所述总的能力需求就是OLT提供的所有业务的理论能力需求。
比如，OLT当前提供的业务有3种：视频会议业务、网络高清电视业务和游戏业务；如果三种业务同时保证为最优配置就超过了OLT能提供的总带宽，那么就可以根据这3种业务的优先级或者业务对带宽大小的敏感度等各种指标，将优先级相对低或者对带宽敏感度差的业务的SLA参数不设置为最优配置，保留为次优配置，比如将网络高清电视业务的SLA参数调低一点。
步骤207：将所述调整后的第一SLA参数和第二SLA参数中至少一个发送给ONT，使所述ONT基于调整后的第一SLA参数和第二SLA参数中至少一个发送和/或接收业务数据。
这样，各业务就可以在OLT的能力范围内，全局管理所有业务的，为所有业务尽可能配置相对合理的参数，以满足所有业务的质量需求。避免在超出OLT能力范围的时候，只关注部分业务，而忽视对其他业务的实际SLA进行优化。
下面以游戏业务切片作为例子描述下行方向的处理方法。当然上行方向也同样适用。用户终端访问游戏服务器后，游戏服务器向用户终端发送游戏业务的数据报文。设定该数据报文头中带有游戏业务的标识。而后处理环节如图3所示，包括：
步骤301：OLT接收到来自上层网络的数据报文，解析该数据报文头中已带有的业务标识，确定所述数据报文对应的业务是游戏业务。
步骤302：OLT采集该业务传输路径上的关键执行指标KPI数据并保存。比如，与游戏业 务体现密切关联的KPI数据至少包括时延大小，与视频业务体现密切关联的KPI数据至少包括卡顿和花屏情况。比如，所述网络KPI数据如下表格1所示，可包括超文本传输协议(Hypertext Transfer Protocol,HTTP)的获取(GET)消息响应成功率、传输控制协议(Transmission Control Protocol,TCP)的建链成功率和建链响应时长、UDP的上下行速率等。更多内容如下表。
其中，OLT采集KPI数据的时长可以根据本地存储或云存储空间大小进行设置，比如本地存储或云存储空间最多可存储30分钟的网络KPI数据。由于本实例是针对游戏业务切片，OLT可以至少采集20分钟内的用户KPI的时延数据，当然也可以进一步采集设备KPI和网络KPI数据。
表格1
Figure PCTCN2022144265-appb-000001
步骤303：分析采集到的KPI数据，OLT检测到某游戏切片用户的数据流时延连续5min 超过100ms，但承诺SLA参数要求的时延范围为0-50ms，此时启动该游戏业务切片的实际SLA参数调整流程。
步骤304：OLT进一步根据收集到的网络KPI分析时延大的原因，判断时延大是因为“WIFI干扰增加导致”，确定调整WIFI信道的QoS模板调整建议以降低数据流时延的具体参数，比如信道宽度、发射功率等，作为新的配置模板发送给ONT进行重配置，其中所述新的配置模板包括WIFI信道调整指示信息。作为一种实施方式，OLT可以通过离线训练的AI算法模型来计算出参数值的大小。
步骤305：ONT收到新的配置模板后，根据WIFI信道调整指示信息，自动扫描邻居接入点(access point，AP)所处信道，发现自身处于2.4G频段#6信道，与周边多个邻居共信道，导致严重的同频干扰，故避开周边领域信道，将本ONT的信道调整为#13信道继续进行游戏业务报文的发送和接收。
步骤306：OLT和ONT重复执行上述的步骤301-305步骤，直到OLT检测到该游戏切片用户的数据流时延基本不超过100ms，则将此时的实际SLA参数保存下来作为该游戏切片用户的SLA参数，用于后续为该游戏切片用户提供游戏业务时使用。
通过使用该实施方案，本方案通过对该游戏切片用户的实际使用效果对实际SLA参数进行监控并优化，从而优化了业务体验；避免了业务提供商只根据承诺SLA参数设定固定网络参数对用户提供服务，不考虑实际的网络环境导致用户实际体验不好而质疑运营商的承诺SLA参数。
进一步地，如果OLT在优化该游戏切片用户的实际SLA参数，还发现有另外一个高清视频切片用户的实际SLA参数也需要优化，但如果同时优化两则的实际SLA参数，可能导致总的服务能力超出了OLT能提供的理论能力最大值。就可以根据这2种业务的优先级或者业务对带宽大小的敏感度等各种指标，将网络高清视频业务切片的实际SLA参数设置低一点。然后将新的实际SLA参数发送给高清视频切片用户的ONT进行配置更新。
