Description

流量控制方法及系统，分组交换设备及用户设备 技术领域
本公开涉及通信领域，具体而言，涉及一种流量控制方法及系统，分组交换设备及用户设备。
背景技术
在相关技术中，分组传送网(Packet Optical Transport Network，简称PTN)的业务，依据其转发特性描述，分为两类：单播业务和组播业务。其中，单播业务通过入接口进入装置，且仅从一个出接口转发离开装置；组播业务，通过入接口进入装置，从至少一个或多个出接口转发离开装置，装置内部复制多份报文，使每个出接口都有一份报文。
电信运营商在网络部署和规划时，单播业务用于重要性更高的应用场景，比如基站回传业务(Backhaul)。组播业务一般用于部署推送业务，比如广播视频业务，由于组播业务存在流量复制，其总体流量会膨胀。共用链路或共用虚拟管道的场景下，单播业务、组播业务要实施流量控制，以避免相互影响，以满足客户的服务质量要求。
相关技术中，在分布式系统报文转发装置，流量控制有两种常用的实现方式：
在介绍相关技术中的技术方案之前，先解释几个技术名词，包处理器(Packet Processor，简称为PP)，交换接入(Switch Access，简称为SA)，交换结构(Switch Fabric，简称为SF)，流量管理(Traffic Management，简称为TM)。
第一种，报文在进入网络接口前实现流量管理，图1是根据相关技术中的PTN设备的网络侧单元流量管理示意图，如图1所示，报文经过PP，封装完整的报文，进入流量管理，报文按业务优先级进入不同的队列，通过配置队列的整形参数，实现流量管理。在相关技术中，单播报文和组播 报文进入不同的业务队列。
采用上述第一种流量控制方法存在下述问题：来自不同来源端口的业务报文，从同一个网络接口出去，报文入相同的队列，排队调度时无法区分不同来源端口的报文，使拥塞避免时无法保证报文按预设权重丢弃，而且，当流量超过出向PTN设备的网络侧单元接口的带宽时，流量控制的反压信号无法正确传递到业务的入口使业务报文缓存以减少送到出接口的报文。这不符合运营商要求的端到端实施流量控制的需求。
在分布式系统报文转发装置，流量控制的第二种方式，单播报文通过交换网时，采用上行授权请求，下行授权应答的方式实现流量管理，图2是根据相关技术中PTN设备的交换侧单元流量管理示意图，如图2所示，实现流量控制的PTN设备的交换接入单元给需要发送报文的单播业务队列按整形信息发布授权信息，单播业务队列根据授权的大小发送对应流量的报文。通过这种协作方式，实现单播业务队列的流量管理。组播业务报文采用自授权的方式通过交换网发送到出向PTN设备的交换接入单元。
采用上述第二种流量控制方式，可以在拥塞发生时，准确将流量控制的反压信号传递给上行队列，使其缓存报文，降低报文发送的速率，缓解拥塞。但是，也存在下述问题：组播业务报文采用自授权的方式，无法精确实施流量控制。
在相关技术中，P2MP是IETF提供的一种实现点-多点的单向业务模型的方法。其特征为：有且仅有一个源(首端)，一个或多个宿(尾端)；业务是单向，从源到宿方向。
相关技术中在实现点对多点主站(Point 2multiple point，简称为P2MP)方法时，采用不同的方法，包括P2MP LSP(Label Switched Path)、P2MP PW(Pseue-wire)。例如，专利公开号CN103716169A的申请文件“点到多点的组播实现方法、网络节点和系统”，描述了通过P2MP LSP实现点到多点的组播业务实现方法；专利公开号CN103430499A的申请文件“在网络虚拟化系统中组播数据通道建立的方法及设备”，描述通过P2MP PW 实现组播数据业务建立和发布。
相关技术中，电信运营商开始使用P2MP来部署广播视频业务，提出了P2MP流量控制的需求，即通过PTN网络时，需要实现P2MP业务的承诺带宽(CIR，Committed Information Rate)和峰值带宽(PIR，Peak Information Rate)，不会受到其他业务的挤占。包括两层场景：
(1)不同站点业务间的挤占
图3是根据相关技术中P2MP应用场景描述图，如图3所示，eNB(Evolved Node B,Lte演进型基站)通过PTN网络接收核心网的P2MP业务，图3中的eNB A接收P2MP业务，eNB A和eNB B共享使用部分链路(节点Core–节点W，节点W-节点M)，eNB A的P2MP业务的带宽要解决拥塞时被eNB B的流量挤占的问题。多媒体广播多播业务网关(Multimedia Broadcast Multicast Sevice_Gateway，简称为MBMS_GW)。
(2)相同站点使用相同管道的不同业务间的挤占
eNB自身的业务间抢占，附图中的eNB C自身的业务有P2MP业务，也有其他类型的单播业务(比如管理信息的流量)，这些业务在拥塞时也会存在流量挤占的问题。
针对相关技术中，业务流量难以控制的问题，目前还没有有效的解决方案。

实施例1

峰值带宽(Peak Information Rate，简称为PIR)，运营商网络为一项业务提供的最大的峰值带宽，单位为比特每秒。在网络拥塞时，超过承诺带宽的流量(即PIR–CIR的带宽)将被首先丢弃，因此，运营商网络不保证超过承诺带宽的流量能被成功的传送。

在本实施例中提供了一种运行于上述分组交换设备的一种流量控制方法，图4是根据本公开实施例的一种流量控制方法的流程图，如图4所示，该流程包括如下步骤：
步骤S402，接收配置信息，其中，该配置信息中携带有组播业务和/或单播业务的承诺带宽；
步骤S404，依据该承诺带宽设置该组播业务和/或该单播业务在分组交换设备的网络侧单元的出口带宽。
通过上述步骤，接收携带有组播业务和/或单播业务的承诺带宽的配置信息，依据该承诺带宽设置该组播业务和/或该单播业务在分组交换设备的网络侧单元的出口带宽，解决了相关技术中业务流量难以控制的问题，达到顺利进行单播业务或者组播业务的用户设置要求。
可选地，设置该组播业务和/或该单播业务在分组交换设备的网络侧单元的出口带宽大于等于该承诺带宽。
可选地，依据该承诺带宽设置该组播业务和/或该单播业务在分组交换设备的网络侧单元的出口带宽的情形可能为以下一种：
在该配置信息中携带有该单播业务的第一承诺带宽，未携带该组播业务的第二承诺带宽的情况下，设置该单播业务的第一出口带宽大于等于该第一承诺带宽，以及将预设出口总带宽与该第一出口带宽之差作为该组播业务的第二出口带宽；
在该配置信息中携带有该组播业务的第二承诺带宽，未携带该单播业务的第一承诺带宽的情况下，设置该组播业务的第二出口带宽大于等于该第二承诺带宽，以及将预设出口总带宽与该第二出口带宽之差作为该单播业务的第一出口带宽；
在该配置信息中携带有该单播业务的第一承诺带宽和该组播业务的第二承诺带宽的情况下，设置该单播业务的第一出口带宽大于等于该第一承诺带宽，该组播业务的第二出口带宽大于等于该第二承诺带宽；
在该配置信息中未携带该单播业务的第一承诺带宽和该组播业务的第二承诺带宽的情况下，设置该单播业务的第一出口带宽为该预设出口总带宽的一半，该组播业务的第二出口带宽为该预设出口总带宽的一半。
可选地，在该配置信息中携带有该单播业务的第一承诺带宽和该组播业务的第二承诺带宽的情况下，可以通过以下公式进行计算得到该单播业务和该组播业务应该分配的带宽。
该第一出口带宽满足以下公式：
Figure PCTCN2017098633-appb-000007
其中，A1表示该第一出口带宽，B1表示该第一承诺带宽，B2表示该第二承诺带宽，C表示该预设出口总带宽；
该第二出口带宽满足以下公式：
Figure PCTCN2017098633-appb-000008
其中，A2表示该第二出口带宽，B1表示该第一承诺带宽，B2表示该第二承诺带宽，C表示该预设出口总带宽。
上述两个公式表示的含义是，在分配单播业务和组播业务时，依据二者的承诺带宽的比例将预设出口总带宽比例划分，以实现最优的分配结果。
可选地，通过分组交换设备的网络侧单元依据该承诺带宽设置该组播业务和/或该单播业务在分组交换设备的网络侧单元的出口带宽。
可选地，依据该承诺带宽设置该组播业务和/或该单播业务在分组交换设备的网络侧单元的出口带宽之前，通过分组交换设备的交换侧单元依据该单播业务的承诺带宽设置该单播业务在分组交换设备的交换侧单元的出口带宽。
上述两个可选实施例中，分组交换设备的交换侧单元保证单播业务的承诺带宽，并计算出单播业务和组播业务的承诺带宽之比，之后，分组交换设备的网络侧单元依据求得的比例进行业务带宽的总管理。
可选地，该配置信息还包括以下至少之一：
业务参数，峰值带宽，承诺突发长度，峰值突发长度。
可选地，通过分组交换设备的交换接入单元依据该业务参数中复制该组播报文，其中，该业务参数中携带有以下信息之一：该组播业务的身份认证ID号，需要复制该组播业务的组播报文的出向逻辑接口，该出向逻辑接口对应的复制份数，其中，该出向逻辑接口位于分组交换设备的网络侧单元。
可选地，该组播业务的带宽参数适用于分组交换设备的网络侧单元的多个出向逻辑接口，并且，该多个出向逻辑接口配置相同的带宽参数，其 中，多个出向逻辑接口是与组播业务相关的接口，该带宽参数包括：该承诺带宽，该峰值带宽，该承诺突发长度，该峰值突发长度。
为了有效的解决上述问题，本公开提出的方法和装置，使用分组交换设备的交换接入单元实现组播报文的逻辑复制，以控制报文复制后的总体流量超过后续处理单元的处理能力；使用两级流量管理(TM，Traffic Management)实现组播业务流量控制，分组交换设备的交换侧单元流量管理实现单播业务的流量控制，以实现单播业务拥塞时公平丢弃，分组交换设备的网络侧单元流量管理实现单播业务、组播业务的总体流量控制。
下面结合本公开优选实施例进行详细说明。
本公开所述的方法包括以下步骤，需要说明的是，以下步骤是分组交换设备的各个部分执行的，但是总的归属于分组交换设备这一侧。
第一步，配置组播业务、单播业务，包括业务参数和带宽参数(承诺带宽、峰值带宽、承诺突发长度、峰值突发长度)。进一步阐述，组播业务的带宽参数针对业务的多个出向逻辑接口生效，而且是相同的。
第二步，组播业务转发和逻辑复制。
组播业务报文通过交换网的空间多播后，报文转发到出向分组交换设备的交换接入单元。分组交换设备的交换接入单元依据配置的组播业务信息，实现组播报文复制。
进一步阐述，配置组播业务时，计算出组播业务的复制信息列表，包括组播ID号(唯一标示)，报文复制到目的端口列表，每个目的端口复制的份数。分组交换设备的交换接入单元依据该信息列表，实施报文复制，且将复制后的组播报文通过调度单元调度到后续处理单元。
第三步，单播业务转发和流量控制。
通过上行授权请求，下行授权应答的实现方式，单播报文在分组交换设备的交换侧单元TM实现流量控制，实现了客户配置的承诺带宽、和峰值带宽。
同一个出端口存在单播报文、和组播报文，依据调度单元的加权轮转调度算法，设置权重以使单播报文的承诺带宽可以全部调度到后续处理单元。进一步阐述，加权调度权重的计算方法为，单播报文调度权重是该出端口单播报文的承诺带宽总和与出端口端口速率的比值。由于组播报文无法在分组交换设备的交换侧单元TM实现流量控制，通过单播报文、组播报文的调度权重，可以保证单播报文、组播报文流量总体过大，导致出端口拥塞的场景下，承诺带宽的报文可以得到调度通过。
进一步阐述，表1是根据本公开实施例中的业务调度权重表，单播、组播业务的调度权重可以计算为表1中所示。
表1
Figure PCTCN2017098633-appb-000009
第四步，组播业务的流量控制。
单播报文、组播报文通过报文处理器后，转发到分组交换设备的网络侧单元TM(即第二级TM)，通过分组交换设备的网络侧单元TM的调度单元、整形单元实现组播业务的流量控制，因为配置业务时出端口端口速率固定(即业务报文从出端口离开装置时，速率固定)。
进一步阐述，调度单元的调度权重控制单播报文、组播报文调度比例，单播报文调度权重，该出端口单播报文的承诺带宽总和与出端口端口速率 的比值；组播报文调度权重，组播业务的承诺带宽总和与出端口速率的比值。通过这种配置方式，整形单元的出向带宽是固定出端口速率，出端口拥塞时，单播报文、组播报文的承诺带宽总和得到保证，此时单播报文调度权重x出端口速率＝单播报文承诺带宽总和,组播报文调度权重x出端口速率＝组播报文承诺带宽总和。
进一步阐述，单播业务报文流量满足承诺带宽要求，即使组播报文经过复制，使组播流量膨胀，单播业务的承诺带宽也得到保证通过，和组播报文共享出端口带宽。同理，组播业务报文流量也满足承诺带宽要求。
图5是根据本公开优选实施例中的两级TM实现流量管理描述图。
图6是根据本公开优选实施例中的两级TM流量管理时报文的流程框图。
以下结合可选三个具体实施例进行详细说明：
具体实施例一 单播业务配置带宽参数，组播业务无带宽参数
图7是根据本公开具体实施例一的流量控制示意图。
某运营商使用网管端到端配置P2MP业务，包括配置带宽参数，且使用P2MP业务部署广播视频业务。网管数据设置到装置。
某分组交换设备核心设备中，参见图7，装置上有单播业务、和P2MP业务，业务参数见下表2，表2是根据具体实施例一的业务信息表格，其中业务的入端口、出端口速率都是1000Mbps。
表2
Figure PCTCN2017098633-appb-000010
Figure PCTCN2017098633-appb-000011
说明：
a、gei_x/y,表示一个物理端口，其中x表示业务单板槽位，y表示业务单板的端口号。
b、gei_x/y.z,表示物理端口上的一个虚拟端口，即业务槽位x，端口y上的子端口z。
c、P2MP业务有两个虚拟出端口，属于同一个物理出端口。
第一步，按上述表项配置单播业务、和P2MP业务，其中组播业务不配置带宽参数，表示组播业务在带宽足够的情况下流量通过，且不保证其带宽。
第二步，P2MP业务转发和逻辑复制。
P2MP业务是组播业务，本例组播报文通过交换网的空间多播后，一份报文发送到出向单板的分组交换设备的交换接入单元。P2MP业务的两个虚拟出接口属于相同的出接口，分组交换设备的交换接入单元对组播报文实施复制，复制一份，以使每个虚拟出接口一份报文。
进一步阐述，配置业务时生成组播ID号，分组交换设备的交换接入单元依据报文头部携带的转发信息识别需要复制的组播ID，实施组播报文复制，且将复制后的报文通过调度单元调度到后续处理单元。
第三步，单播业务转发和流量控制。
单播业务通过交换网转发报文时，向下行交换接入(本例中是5#槽位的交换接入)申请授权信息，下行交换接入依据分组交换设备的交换侧单元TM的整形配置信息应答授权申请，单播业务发送授权对应的流量的报文。
在本例中，有两条单播业务，流量总和超过了出端口速率 (600Mbps+600Mbps＝1200Mbps，大于出端口速率为1000Mbps)，出端口发生单播报文拥塞，通过分组交换设备的交换侧单元TM实施单播总体流量控制。分组交换设备的交换侧单元TM整形时先保证业务的承诺带宽，有多余带宽时按比例分配给业务，但是业务的总体带宽不会超过峰值带宽。所以，单播业务一的通过流量为400Mbps，单播业务二的通过流量为600Mbps，即通过分组交换设备的交换侧单元TM的流量控制，单播总体流量为1000Mbps。
组播业务通过交换网时，采用自授权的方式，即组播业务无法在分组交换设备的交换侧单元TM实现流量控制。在本例中，P2MP业务流量400Mbps，逻辑出接口有两个，通过分组交换设备的交换接入单元的报文复制，实际送到下一级处理的流量为400Mbps x 2＝800Mbps。理论上出端口总体流量为1000Mbps(单播总体流量)+800Mbps(组播总体流量，每个P2MP出接口有一份组播带宽)＝1800Mbps，超过了出端口速率。调度单元通过单播、组播业务的调度权重来实施业务的调度，以保证单播业务的承诺带宽总和可以保证通过。单播业务的调度权重为单播总体的承诺带宽总和与出端口速率的比值。在本实施例中，单播总体的承诺带宽总和等于业务一的承诺带宽(300M)+业务二的承诺带宽(600M)，则单播报文调度权重为900M/1000M＝0.9。
进一步阐述，组播业务的调度权重为(出端口速率(1000Mbps)–单播总体的承诺带宽总和(900M))与出端口速率的比值，则组播报文的调度权重为100M/1000M＝0.1。即单播业务和组播业务的调度权重为0.9:0.1＝9:1。通过调度单元的加权轮转调度算法调度，即使组播流量非常大，单播报文的承诺带宽总和可以保证通过。本例中，调度到下一级处理单元的流量为1000Mbps单播业务(其中承诺带宽900M流量)，800Mbps的组播业务。
第四步，组播业务的流量控制。
单播报文、组播报文通过报文处理器处理后，送到分组交换设备的网 络侧单元TM，通过分组交换设备的网络侧单元的调度单元、和整形单元实现总体流量控制。
调度单元的权重计算，单播报文调度权重＝单播总体的承诺带宽总和/出端口速率，即900Mbps/1000Mbps＝0.9,组播报文的调度权重＝(出端口速率-单播总体承诺带宽总和)/出端口速率，即(1000Mbps-900Mbps)/1000Mbps＝0.1。则单播业务与组播业务的调度权重为9:1。
本例中，出端口速率是1000Mbps，整形单元也按此速率整形，依据调度权重，可理论计算出单播业务的出向流量为1000Mbps x 0.9/(0.9+0.1)＝900Mbps，组播业务出向流量为1000Mbps x 0.1/(0.9+0.1)＝100Mbps。超过上述带宽的报文将被丢弃。
本实例，单播业务一的出向流量为300Mbps，单播业务二的出向流量为600Mbps，P2MP业务的每个逻辑出接口的出向流量为50Mbps。很明显，业务的承诺带宽都得到保证通过。
采用分组交换设备的交换接入单元实施组播报文逻辑复制，以限制复制后报文的总体流量，避免超过后续报文处理器的处理能力。通过两级流量管理(分组交换设备的交换侧单元TM、和分组交换设备的网络侧单元TM)控制单播、组播业务的流量，其中，分组交换设备的交换侧单元TM控制单播业务的总体流量，通过调度单元的调度，单播业务的承诺带宽可以保证通过，分组交换设备的网络侧单元TM控制单播、组播业务的总体输出流量。
具体实施例二 单播业务无带宽参数，组播业务无带宽参数
图8是根据本公开具体实施例二的流量控制示意图。
某分组交换设备核心设备中，参见实施例图8，装置上有单播业务、和P2MP业务，业务参数见下表3，表3是根据本公开具体实施二的业务信息表格，其中业务的入端口、出端口速率都是1000Mbps。
表3
Figure PCTCN2017098633-appb-000012
第一步，按上述表项配置单播业务、和P2MP业务，其中组播业务不配置带宽参数，表示组播业务在带宽足够的情况下流量通过，且不保证其带宽。单播业务也不配置带宽参数，表示单播业务在带宽足够的情况下流量通过，也不保证其带宽。
第二步，P2MP业务转发和逻辑复制。
第三步，单播业务转发和流量控制。
单播业务通过交换网转发报文时，向下行交换接入(本例中是5#槽位的交换接入)申请授权信息，下行交换接入依据分组交换设备的交换侧单元TM的整形配置信息应答授权申请，单播业务发送授权对应的流量的报文。
在本例中，有两条单播业务，流量总和超过了出端口速率(600Mbps+600Mbps＝1200Mbps，大于出端口速率为1000Mbps)，出端口发生单播报文拥塞，通过分组交换设备的交换侧单元TM实施单播总体流量控制。单播业务未配置带宽参数，仅控制单播总体流量不超过出端口速率即可，所以单播业务一的通过流量为500Mbps，单播业务二的通过流量为500Mbps，即通过分组交换设备的交换侧单元TM的流量控制，单播总体流量为1000Mbps。
组播业务通过交换网时，采用自授权的方式，即组播业务无法在分组交换设备的交换侧单元TM实现流量控制。在本例中，P2MP业务流量 400Mbps，逻辑出接口有两个，通过分组交换设备的交换接入单元的报文复制，实际送到下一级处理的流量为400Mbps x 2＝800Mbps。理论上出端口总体流量为1000Mbps(单播总体流量)+800Mbps(组播总体流量，每个P2MP出接口有一份组播带宽)＝1800Mbps，超过了出端口速率。单播业务、和组播业务都未配置承诺带宽，故单播业务的调度权重为0.5，组播业务的调度权重也为0.5，单播业务和组播业务的调度权重为0.5:0.5＝1:1。通过调度单元的加权轮转调度算法调度，单播、组播业务按权重调度进入下一级处理单元。本例中，调度到下一级处理单元的流量为1000Mbps单播业务，800Mbps的组播业务。
第四步，组播业务的流量控制。
单播报文、组播报文通过报文处理器处理后，送到分组交换设备的网络侧单元TM，通过分组交换设备的网络侧单元的调度单元、和整形单元实现总体流量控制。
调度单元的权重计算，单播业务和组播业务都未配置承诺带宽，则单播业务与组播业务的调度权重为1:1。
本例中，出端口速率是1000Mbps，整形单元也按此速率整形，依据调度权重，可理论计算出单播业务的出向流量为1000Mbps x 0.5/(0.5+0.5)＝500Mbps，组播业务出向流量为1000Mbps x 0.5/(0.5+0.5)＝500Mbps。超过上述带宽的报文将被丢弃。
本实例，单播业务一的出向流量为250Mbps，单播业务二的出向流量为250Mbps，P2MP业务的每个逻辑出接口的出向流量为250Mbps。
具体实施例三 单播业务配置带宽参数，组播业务配置带宽参数

第一步，按上述表项配置单播业务、和P2MP业务，组播业务和单播业务都配置带宽参数，拥塞时必须保证业务的承诺带宽。
第二步，P2MP业务转发和逻辑复制。
第三步，单播业务转发和流量控制。
单播业务通过交换网转发报文时，向下行交换接入(本例中是5#槽位的交换接入)申请授权信息，下行交换接入依据分组交换设备的交换侧单元TM的整形配置信息应答授权申请，单播业务发送授权对应的流量的报文。
在本例中，有两条单播业务，流量总和超过了出端口速率(600Mbps+600Mbps＝1200Mbps，大于出端口速率为1000Mbps)，出端口发生单播报文拥塞，通过分组交换设备的交换侧单元TM实施单播总体流量控制。
调度时先保证业务的承诺带宽，剩余带宽(端口速率-承诺带宽总和)由业务按权重分配(默认情况是1:1分配)。这样，通过分组交换设备的交换侧单元TM的流量控制，单播总体流量为1000Mbps。
组播业务通过交换网时，采用自授权的方式，即组播业务无法在分组交换设备的交换侧单元TM实现流量控制。在本例中，P2MP业务流量400Mbps，逻辑出接口有两个，通过分组交换设备的交换接入单元的报文复制，实际送到下一级处理的流量为400Mbps x 2＝800Mbps。理论上出端口总体流量为1000Mbps(单播总体流量)+800Mbps(组播总体流量，每个P2MP出接口有一份组播带宽)＝1800Mbps，超过了出端口速率。单播业务调度权重为单播业务承诺带宽总和/端口速率＝(300Mbps+400Mbps)/1000Mbps＝0.7。组播业务的调度权重为组播业务承诺带宽总和/端口速率＝100Mbps x 2/1000Mbps＝0.2。单播业务和组播业务的调度权重为0.7:0.2＝7:2。通过调度单元的加权轮转调度算法调度，单播、组播业务按权重调度进入下一级处理单元。本例中，调度到下一级处理单元的流量为1000Mbps单播业务，800Mbps的组播业务。
第四步，组播业务的流量控制。
单播报文、组播报文通过报文处理器处理后，送到分组交换设备的网络侧单元TM，通过分组交换设备的网络侧单元的调度单元、和整形单元实现总体流量控制。
调度单元的权重，见第三步，单播业务与组播业务的调度权重为7:2。
本例中，出端口速率是1000Mbps，整形单元也按此速率整形，依据调度权重，可理论计算出单播业务的出向流量为1000Mbps x 7/(7+2)＝778Mbps，组播业务出向流量为1000Mbps x 2/(7+2)＝222Mbps。超过上述带宽的报文将被丢弃。
本实例，单播业务一的出向流量为339Mbps，单播业务二的出向流量为439Mbps，P2MP业务的每个逻辑出接口的出向流量为111Mbps。很明显，业务的承诺带宽都得到保证通过。
具体实施例四，单播业务配置未带宽参数，组播业务配置带宽参数
图10是根据本公开具体实施例四的流量控制示意图。
某分组交换设备核心分组交换设备中，参见实施例图10，装置上有单播业务、和P2MP业务，业务参数见下表5，表5是根据具体实施例四的业务信息表，其中业务的入端口、出端口速率都是1000Mbps。

第一步，按上述表项配置单播业务、和P2MP业务，单播业务未配置带宽参数，组播业务配置有带宽参数，端口拥塞时必须保证业务的承诺带宽。
第二步，P2MP业务转发和逻辑复制。
第三步，单播业务转发和流量控制。

在本例中，有两条单播业务，流量总和超过了出端口速率(600Mbps+600Mbps＝1200Mbps，大于出端口速率为1000Mbps)，出端口发生单播报文拥塞，通过分组交换设备的交换侧单元TM实施单播总体流量控制。这样，通过分组交换设备的交换侧单元TM的流量控制，单播总体流量为1000Mbps。
组播业务通过交换网时，采用自授权的方式，即组播业务无法在分组交换设备的交换侧单元TM实现流量控制。在本例中，P2MP业务流量400Mbps，逻辑出接口有两个，通过分组交换设备的交换接入单元的报文复制，实际送到下一级处理的流量为400Mbps x 2＝800Mbps。理论上出端口总体流量为1000Mbps(单播总体流量)+800Mbps(组播总体流量，每个P2MP出接口有一份组播带宽)＝1800Mbps，超过了出端口速率。组播业务的调度权重为组播业务承诺带宽总和/端口速率＝100Mbps x 2/1000Mbps＝0.2，单播业务未配置带宽参数，则单播业务的调度权重为(端口速率–组播业务承诺带宽总和)/端口速率＝(1000Mbps–2x100Mbps)/1000Mbps＝0.8。单播业务和组播业务的调度权重为0.8:0.2＝8:2。通过调度单元的加权轮转调度算法调度，单播、组播业务按权重调度进入下一级处理单元。本例中，调度到下一级处理单元的流量为1000Mbps单播业务，800Mbps的组播业务。
第四步，组播业务的流量控制。

调度单元的权重，见第三步，单播业务与组播业务的调度权重为8:2。
本例中，出端口速率是1000Mbps，整形单元也按此速率整形，依据调度权重，可理论计算出单播业务的出向流量为1000Mbps x 8/(8+2)＝800Mbps，组播业务出向流量为1000Mbps x 2/(8+2)＝200Mbps。超过上述带宽的报文将被丢弃。
本实例，单播业务一的出向流量为400Mbps，单播业务二的出向流量为400Mbps，P2MP业务的每个逻辑出接口的出向流量为100Mbps。很明显，业务的承诺带宽都得到保证通过。
通过执行本申请文件中记载的方法，分组交换设备的交换接入单元实现组播报文复制，以控制报文复制后的总体流量超过后续处理单元的处理 能力,分组交换设备的交换侧单元TM实现单播报文流量控制，通过设置分组交换设备的交换侧单元TM中调度单元单播报文、组播报文的权重，保证单播业务的承诺带宽，通过分组交换设备的网络侧单元TM的调度单元的调度、和整形单元的流量控制，组播业务的总体流量也得到控制，很好的解决了单播业务、组播业务共存时的竞争带宽的问题,使单播业务、组播业务的承诺带宽都可以得到保证。
