Description

带宽的分配、带宽的检查方法及装置 技术领域
本发明实施例涉及通信领域，具体而言，涉及一种带宽的分配、带宽的检查方法及装置。
背景技术
无源光网络(PON，Passive Optical Network)架构是一种点到多点的网络架构，由光线路终端(OLT，Optical Line Terminal)、光分配网络(ODN，Optical Distribute Network)和光网络单元(ONU，Optical Network Unit)组成，光线路终端通过ODN与多个光网络单元连接。
无源光网络是一种点到多点的网络拓扑，ONU的上行发送需要OLT通过带宽分配进行协调，以免不同ONU发送的信号发生冲突，无源光网络系统一般通过动态带宽分配(DBA，Dynamic Bandwidth Assignment)计算各ONU的上行带宽。传统的DBA算法一般依赖ONU的状态报告或者OLT的流量检测，仅考虑ONU所需上行带宽的大小，以及上行带宽的利用率，很少考虑上行带宽分配的延时、抖动等因素，最多是兼顾上行带宽分配的延时、抖动。
随着移动业务的发展，无源光网络系统逐渐成为移动业务的承载技术之一，而移动业务对承载网络的传输延迟提出了很严格的要求，例如，目前业界针对无源光网络系统承载5G前传业务提出的传输延迟要求控制在100微秒以内。仅考虑带宽大小的动态带宽分配方法会带来较大的上行数据传输延迟，现有的无源光网络系统较难满足移动业务所需的传输延迟要求。
发明内容
本发明实施例提供了一种带宽的分配、带宽的检查方法及装置，以至 少解决相关技术中无源光网络系统较难满足移动业务所需的传输延迟要求的问题。

根据本发明的一个实施例，提供了一种带宽的检查方法，包括：对业务远端设备与业务局端设备之间的交互信息进行检查，以获取所述交互信息中与带宽相关的协议包中的业务控制信令；将所述业务控制信令转换为第一带宽信息，并根据所述第一带宽信息为光网络单元ONU进行带宽分配，其中，所述带宽信息包括：分配至所述ONU的带宽对应的带宽大小，分配至所述ONU的带宽对应的延迟大小以及开始时间。
根据本发明的一个实施例，提供了一种带宽的分配装置，包括：第一获取模块，设置为获取为光网络单元ONU分配带宽的第一相关信息，其中，所述第一相关信息至少包括：与带宽相关的协议包中的业务控制信令；第一分配模块，设置为将所述第一相关信息转换为第一带宽信息，并根据所述第一带宽信息为所述ONU进行带宽分配，其中，所述第一带宽信息包括：分配至所述ONU的带宽对应的带宽大小，分配至所述ONU的带宽对应的延迟大小以及开始时间。
根据本发明的一个实施例，提供了一种带宽的检查装置，包括：检查模块，设置为对业务远端设备与业务局端设备之间的交互信息进行检查，以获取所述交互信息中与带宽相关的协议包中的业务控制信令；第三分配模块，设置为将所述业务控制信令转换为第一带宽信息，并根据所述第一带宽信息为光网络单元ONU进行带宽分配，其中，所述带宽信息包括：分配至所述ONU的带宽对应的带宽大小，分配至所述ONU的带宽对应 的延迟大小以及开始时间。
根据本发明的又一个实施例，还提供了一种存储介质，所述存储介质中存储有计算机程序，其中，所述计算机程序被设置为运行时执行上述任一项方法实施例中的步骤。
根据本发明的又一个实施例，还提供了一种电子装置，包括存储器和处理器，所述存储器中存储有计算机程序，所述处理器被设置为运行所述计算机程序以执行上述任一项方法实施例中的步骤。
通过本发明实施例，由于带宽申请和分配不再仅仅依赖传统的ONU的状态报告或者OLT的流量检测，也不仅仅考虑带宽大小。DBA除了考虑带宽大小外，还考虑带宽延时和开始时间，因此，能够解决相关技术中无源光网络系统较难满足移动业务所需的传输延迟要求的问题，从而达到了降低无源光网络系统的传输延迟的效果。

下文中将参考附图并结合实施例来详细说明本发明实施例。
需要说明的是，本发明的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。
在本实施例中提供了一种带宽的分配方法，图1是根据本发明实施例的一种带宽的分配方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，获取为光网络单元ONU分配带宽的第一相关信息，其中，所述第一相关信息至少包括：与带宽相关的协议包中的业务控制信令；
步骤S104，将所述第一相关信息转换为第一带宽信息，并根据所述第一带宽信息为所述ONU进行带宽分配，其中，所述第一带宽信息包括：分配至所述ONU的带宽对应的带宽大小，分配至所述ONU的带宽对应的延迟大小以及开始时间。
需要说明的是，在本实施例中描述的延迟大小主要有两种。一种是数据达到ONU的时间，以及之后发送至OLT的时间的二者时间差值。而另一种则是数据在ONU中的缓存时间，即数据从ONU发送到OLT的延迟，减去数据从ONU到OLT的传输时间。
需要说明的是，在本实施例的开始时间是指，在带宽分配过程持续的过程当中，带宽分配的起始时间点对应的时间。
具体而言，由于与带宽相关的协议包中的业务控制信令并不是亘古不变的，而是实时更新的动态信息。因此，只要接受到业务控制信令，就需要判断是否与原有接收的业务控制信令相同。如果不相同则根据业务控制信令中包含的信息进行更新带宽大小以及延迟大小。
可选地，获取为光网络单元ONU分配带宽的第一相关信息，至少包括以下其中之一：在所述ONU获取业务流中所述与带宽相关的协议包的过程中，接收所述ONU主动上报的所述业务控制信令；在所述ONU获取业务流中所述与带宽相关的协议包的过程中，向所述ONU发送用于请求所述ONU上报所述业务控制信令的第一请求信息，并接收所述ONU根据所述第一请求信息上报的业务控制信令。
例如，以ONU与OLT的交互为例。ONU实时接收业务流中的组播交互信息(IGMP join，leave等)。在该组播交互信息中携带与带宽相关的协议包中的业务控制信令。一方面，ONU可以自己主动上报该接收的组播交互信息。同时另一方面，考虑到ONU可能来不及上报组播交互信息或者ONU还需要执行其他功能导致无法主动上报组播交互信息，此时，OLT通过请求ONU上报所述业务控制信令的第一请求信息。而后ONU会将组播交互信息中的业务控制信令响应上报至OLT。
另一方面OLT自身也同样能够实时接收业务流中的组播交互信息，然后根据组播交互信息中携带的与带宽相关的协议包中的业务控制信令执行后续的操作。
需要指出的是，为了加快分配效率，OLT与ONU可以预先协商实时接收业务流中的组播交互信息的类型。例如，对于最高优先级的业务控制信令，可以由OLT本身来实时接收。而对于优先级次高的业务控制信令，可以通过OLT来实时接收并主动上报。最后对已优先级低的业务控制信令，OLT由于不需要即时处理，因此可以通过发送第一请求信息的方式，在需求处理后，向ONU发送，以获取ONU响应的业务控制信令。
可选地，所述方法还包括：获取为光网络单元ONU分配带宽的第二相关信息，其中，所述第二相关信息至少包括：ONU设备信息，所述ONU支持的业务类型；将所述第二相关信息转换为第二带宽信息，并根据所述第二带宽信息为所述ONU进行带宽分配，其中，所述第二带宽信息包括：分配至所述ONU的带宽对应的带宽大小，分配至所述ONU的带宽对应的延迟大小。
具体而言，ONU设备信息，所述ONU支持的业务类型都是ONU固有的信息。因此，确定的带宽大小和延迟大小都是静态信息。获取转换一次即可确定。
可选地，取为光网络单元ONU分配带宽的第二相关信息，至少包括以下其中之一：在所述ONU获取业务流中的业务信息的过程中，接收所 述ONU主动上报的所述ONU支持的业务类型对应的业务信息；或，在所述ONU获取业务流中的业务信息的过程中，向所述ONU发送第一请求信息，并接收所述ONU根据所述第一请求信息上报的业务信息，其中，所述第一请求信息用于请求所述ONU上报支持的业务类型对应的业务信息。
可选地，接收所述ONU自主上报的所述ONU设备信息；或，向所述ONU发送第二请求信息，并接收所述ONU根据所述第二请求消息上报的所述ONU设备信息，其中，所述第二请求信息用于请求所述ONU上报所述ONU设备信息的类型；其中，所述ONU设备信息的类型至少包括：所述ONU的设备类型，所述ONU的物理端口的类型。
例如，以ONU与OLT的交互为例。ONU可以获取自身的设备类型、物理端口的类型以及所支持的业务类型。一方面，ONU可以自己主动上报自身的设备类型、物理端口的类型以及所支持的业务类型。同时另一方面，考虑到ONU可能来不及上报或者ONU还需要执行其他功能导致无法主动上报，此时，OLT通过请求ONU上报自身的设备类型、物理端口的类型以及所支持的业务类型的第二请求信息。而后ONU会将自身的设备类型、物理端口的类型以及所支持的业务类型响应上报至OLT。
需要指出的是，为了加快分配效率，OLT与ONU可以预先协商具体上报的方式。例如，ONU主动上报自身的设备类型，OLT则可以请求ONU上报物理端口的类型以及所支持的业务类型。在此不做过多赘述。
可选地，所述方法还包括：在获取相关信息后，控制器将所述相关信息转换为带宽信息，并向DBA装置发送所述带宽信息进行带宽分配；或，在获取相关信息后，控制器将所述相关信息发送至OLT；所述OLT将所述相关信息转换为带宽信息，并向DBA装置发送所述带宽信息进行带宽分配。
可选地，所述方法还包括：在获取相关信息后，所述ONU将所述相关信息转换为带宽信息，并向DBA装置发送所述带宽信息进行带宽分配； 或，在获取相关信息后，所述ONU将所述相关信息发送至OLT；所述OLT将所述相关信息转换为带宽信息，并向DBA装置发送所述带宽信息进行带宽分配。
需要指出的是，DBA装置是用于执行动态带宽分配的装置。该DBA装置可以驻留在OLT当中，也可驻留在OLT之外的其中装置当中。具体的设置方式根据实际需要来确定。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明实施例的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。

步骤S202，对业务远端设备与业务局端设备之间的交互信息进行检查，以获取所述交互信息中与带宽相关的协议包中的业务控制信令；
步骤S204，将所述业务控制信令转换为第一带宽信息，并根据所述第一带宽信息为光网络单元ONU进行带宽分配，其中，所述带宽信息包括：分配至所述ONU的带宽对应的带宽大小，分配至所述ONU的带宽对应的延迟大小以及开始时间。
可选地，所述交互信息还包括：ONU设备信息，所述ONU支持的业务类型；所述方法还包括：将所述ONU设备信息或所述ONU支持的业务类型转换为第二带宽信息，并根据所述第二带宽信息为光网络单元ONU进行带宽分配，其中，所述带宽信息包括：分配至所述ONU的带宽对应 的带宽大小，分配至所述ONU的带宽对应的延迟大小。
需要说明的是，在本实施例中，业务远端设备与业务局端设备的组合包括但不限于，BBU(Baseband Unit，基带单元)与RRU(Remote Radio Unit，远端射频单元)。UE(User End，用户终端)与CU(Central Unit，中央单元)/DU(Distributed Unit，分布单元)，子设备与站点设备。
可选地，光线路终端OLT对所述业务远端设备与所述业务局端设备之间的交互信息进行检查；所述OLT将检查结果转换为带宽信息，并根据所述带宽信息为所述ONU进行带宽分配。
可选地，所述ONU对所述业务远端设备与所述业务局端设备之间的交互信息进行检查；所述ONU将检查结果发送至OLT；所述OLT将所述检查结果转换为带宽信息，并根据所述带宽信息为所述ONU进行带宽分配。
可选地，所述ONU对所述业务远端设备与所述业务局端设备之间的第一交互信息进行检查；所述ONU将第一检查结果发送至OLT；OLT对所述业务远端设备与所述业务局端设备之间的第二交互信息进行检查；所述OLT将从所述ONU接收到的所述第一检查结果以及本地检查的第二检查结果转换为带宽信息，并根据所述带宽信息为所述ONU进行带宽分配。
为了更好的理解上述实施例中记载的方案，在实施例2中还提供了如下4种场景进行理解：
场景1：
图3是根据本发明实施例的一种无源光网络系统架构的结构图，无源光网络系统在BBU和RRU之间，承载移动业务，如4G/5G前传业务，BBU和RRU之间的协议流通过无源光网络系统进行交互，无源光网络系统检查BBU和RRU之间的协议流，获取业务类型(如5G业务)、业务量/带宽相关的协议包等内容，分析这些数据后产生DBA相关需求。查模块可以驻留在OLT中，可以驻留在ONU中，也可以同时驻留在OLT和ONU中，如图3所示的检查模块。
场景2：
图4是根据本发明实施例的一种无源光网络系统UE分配带宽的流程图，检查DBA驻留在OLT中的工作过程，以给手机UE分配带宽的过程
步骤1：UE在时隙N中发送数据，并为空口请求将来的某一时隙N+A(对LTE来说是N+8)；
步骤2：CU/DU进行带宽调度计算后，通知各UE为其分配的有关将来时隙N+A的空口资源。
步骤3：OLT检查CU/DU发给各UE的时隙N+A的调度分配，将时隙N+A匹配到RRU、ONU、T-CONT(Transmission Container，传输容器)甚至GEM–Port(GPON Encapsulation Method–Port，GPON分装方法端口)；
步骤4：OLT根据检查到的给各ONU的调度分配，推算每个RRU相应的前传业务量，OLT将每个RRU的带宽进一步匹配到T-CONT并分配给ONU。
步骤5：各UE在时隙N+A中发送上行业务，这些业务在RRU中处理并在PON上作为前传数据包传输，同时各UE发送申请将来时隙N+2*A。
场景3：
图5是根据本发明实施例另一种无源光网络系统UE分配带宽的流程图，检查DBA驻留在ONU中的工作过程，以给手机UE分配带宽的过程
步骤1：UE在时隙N中发送数据，并为空口请求将来的某一时隙N+A(对LTE来说是N+8)；
步骤2：ONU检查时隙N+A的请求，并将该请求转换为DBA请求并发送至OLT。
步骤3：CU/DU进行带宽调度计算后，通知各UE为其分配的有关将 来时隙N+A的空口资源。
步骤4：OLT推算每个RRU相应的前传业务量，OLT将每个RRU的带宽进一步匹配到T-CONT并分配给ONU。
步骤5：各UE在时隙N+A中发送上行业务，这些业务在RRU中处理并在PON上作为前传数据包传输，同时各UE发送申请将来时隙N+2*A。
场景4：
图6是根据本发明实施例一种无源光网络系统的分配带宽的流程图，如图6所示，当站点设备控制子设备的上行业务时，站点设备知晓上行传输的达到时间以及业务大小。如果OLT与站点设备共享调度信息的话，OLT能够在不用等待ONU发送状态报告的情况下执行DBA，这意味着能够减少延迟并几乎达到点到点的业务传输。
