具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
随着WiFi技术的普及，每年都有海量WiFi产品发货，WiFi协议是基于竞争的协议，同一区域内OBSS网络增多，干扰冲突的概率逐渐变大，WiFi用户的体验变差。由于AP可以同时调度多个终端，多个终端需要竞争信道，WiFi6引入OFDMA技术，可以减少信道冲突，提升用户体验。但是，复杂、时变的干扰以及多个用户同时竞争信道给WiFi性能测试带来了挑战。当前的WiFi性能测试系统存在干扰单一，支持的用户数少等问题。
图1为一种WiFi通信的性能测试系统的示意图。该测试系统包括多用户模块、MPE模块、干扰生成器模块、以及主测箱体。主测箱体中包括转台，转台上用于放置待测AP或待测终端。MPE模块内置衰减器，MPE模块用于模拟多用户模块至主测箱体之间的路径通道。该测试系统可以实现单用户的信号峰值、速度和距离(rate vs range，RVR)、抗干扰、方向性测试，也可以实现16个用户以下的吞吐和时延测试。
该WiFi通信的性能测试系统的干扰生成器模块可以简称为干扰模块，该干扰模块采用干扰录制的原理把其他环境的干扰报文抓包后导入到Igen模块进行回放，但是回放的干扰报文是不会进行冲突退让的，不符合WiFi协议要求。
图2为WiFi通信的性能测试系统中的多用户模块的示意图。该多用户模块为图1中的多用户模块，该多用户模块由16个Intelax200芯片组成，16个Intelax200芯片通过快捷外围部件互连标准(peripheral component interconnect express，PCIE)插槽放在同一个PCB板上，16个Intelax200芯片通过功分器合路后与MPE模块连接。由于该多用户模块最多支持16个用户，该多用户模块支持的用户数较少。
多用户模块、待测终端和个人计算机(personal computer，PC)/服务器上都部署了数据测量模块，数据测量模块采用开源工具iper2和iperf3，在WiFi性能测试时iperf2和iperf3的测试结果容易出现0Mbps的情况，尤其是多用户场景，经常会出现几个用户的吞吐为0Mbps。因为空口传输是不可靠传输，用于建立传输控制协议(transmission control protocol，TCP)连接的同步(synchronize，SYC)报文可能会在空口上丢失，导致TCP建链失败；尤其是在多用户场景中不同用户竞争空口资源，加剧了SYC报文传输失败的可能。
该WiFi通信的性能测试系统存在如下缺点：(1)多用户模块的用户集成度低，价格昂贵；(2)测试系统存在缺陷，多用户测试时会出现部分用户的吞吐为0Mbps；(3)干扰模块只产生1路干扰，且干扰模块发出的WiFi干扰不会进行冲突退让，和真实的WiFi干扰不符。
为此，本申请实施例提出了一种测试装置，应用于无线保真通信的性能测试，能够提升用户数量，降低WiFi通信的性能测试装置的成本。
图3为本申请实施例提供的测试装置的示意图。该测试装置包括：多用户模块310，所述多用户模块310包括处理模块311、PCIE桥312、和多个终端接口313。PCIE桥312用于处理模块311与多个终端接口313之间的通信，PICE桥312与处理模块311是连接的，PICE桥312包括多个支路节点314，多个支路节点314与多个终端接口313是一一对应连接的。可以理解为，PICE桥312的一端与处理模块311是连接的，PICE桥312的另一端与多个终端接口313是连接的。其中，处理模块311可以为中央处理器(central processing unit，CPU)，终端接口可以为M.2接口，也可以是PCIE X1接口。
可选的，多个终端接口与多个辅助终端是一一对应连接的，多用户模块还包括多个辅助终端。多个支路节点中的第一支路节点用于控制该第一支路节点对应的第一支路的通断，第一支路包括第一支路节点、第一支路节点连接的第一终端接口、以及第一终端接口连接的第一辅助终端，其中，多个终端接口包括第一终端接口，多个辅助终端包括第一辅助终端。
可选的，多个辅助终端与第一合路器是连接的，第一合路器用于将M路信号合为N路信号，M大于N，M、N为正整数。可选的，第一合路器与多个第一衰减器是连接的，多个第一衰减器中每个第一衰减器的衰减系数是可调的；通过调整第一衰减器的衰减系数，可以调整辅助终端所产生的信号的信号强度。其中，第一衰减器的数量小于或等于N。例如，M＝12、N＝4，第一合路器可以将12路信号合为4路信号，经过第一合路器合路后的4路信号中每2路信号可以连接一个第一衰减器，或者，经过第一合路器合路后的4路信号中每1路信号可以连接一个第一衰减器。
示例性地，多用户模块包括多个PC，每个PC包括处理模块、PCIE桥、和多个终端接口，每个终端接口连接一个辅助终端。图4为本申请实施例的多用户模块中一个PC的示意图。处理模块以CPU为例，CPU与PICE桥是连接的，PICE桥包括的多个支路节点与多个终端接口一一对应是连接的，多个终端接口与多个辅助终端是一一对应连接的。多个辅助终端与第一合路器是连接的，第一合路器与多个第一衰减器是连接的。多个辅助终端通过第一合路器、衰减系数可调的多个第一衰减器、以及天线可以将产生的信号引入主测箱体，主测箱体用于放置待测终端或待测AP。
本申请实施例提供的技术方案中，多用户模块包括处理模块、PCIE桥、和多个终端接口，PCIE桥用于处理模块与多个终端接口之间的通信，PICE桥的一端与处理模块是连接的，PICE桥的另一端与多个终端接口是连接的，每个终端接口可以连接一个辅助终端/用户。因此，该多用户模块可以包括多个辅助终端，且该多用户模块的集成度高、价格便宜。
在一种实现方式中，该测试装置还包括时钟同步模块，该时钟同步模块是通过有线网络与多用户模块连接的，该时钟同步模块是安装在服务器/主机电脑上的，该时钟同步模块可以通过软件的方式实现。该时钟同步模块用于通过有线网络将多个辅助终端的时钟与安装了该时钟同步模块的服务器/主机电脑的时钟进行同步。本申请实施例中的有线网络用于传输管理报文。
可选的，该时钟同步模块是通过有线网络与主测箱体中的待测终端连接的。该时钟同步模块还用于通过有线网络将待测终端的时钟与安装了该时钟同步模块的服务器/主机电脑的时钟进行同步。
图5为本申请实施例的测试装置中的时钟同步模块与待测终端通过有线网络连接的示意图。以时钟同步模块安装在服务器上为例，待测终端可以通过type C转以太网卡与该安装了时钟同步模块的服务器之间搭建一条有线网络，时钟同步模块通过有线网络可以将待测终端的时钟与该服务器的时钟进行同步，从而可以测量待测终端与服务器之间的单向时延和往返时延。其中，服务器与AP之间也是通过有线网络连接的，AP与待测终端之间是通过WiFi通信的。
因此，本申请实施例提供的测试装置不仅可以测量辅助终端/待测终端WiFi通信的往返时延，还可以测量辅助终端/待测终端WiFi通信的单向时延。
在一种实现方式中，该测试装置还包括流量测试模块，该流量测试模块是安装在服务器/主机电脑上的，该流量测试模块是通过有线网络与多用户模块连接的，该流量测试模块用于测量来自多用户模块中多个辅助终端的业务数据的流量。

示例性地，该流量测试模块包括有线接口和无线接口，有线接口用于通过有线网络传输管理报文，无线接口用于通过无线保真网络传输数据报文。
图6为流量测试模块与多用户模块中多个辅助终端通过有线网络连接的示意图。示例性地，多用户模块包括6个PC，每个PC包括处理模块、PCIE桥、和12个终端接口，每个终端接口连接一个辅助终端，该多用户模块共包括72个辅助终端。该流量测试模块的有线接口是用于通过有线网络与多用户模块中的辅助终端传输管理报文的，该流量测试模块的无线接口是用于通过无线保真网络与辅助终端传输数据报文的。应理解，本申请实施例中的多用户模块包括的PC的数量也可以为6个以上，对此不做具体限定。
本申请实施例中辅助终端/待测终端可以通过有线网络与包括流量测试模块的服务器连接，辅助终端/待测终端与服务器/流量测试模块之间通过有线网络传输用于建立TCP连接的管理报文，辅助终端/待测终端与服务器/流量测试模块之间通过无线保真网络传输数据报文，能够实现管理报文通道与数据报文通道的分离，可以避免多用户场景下辅助终端/待测终端与服务器/流量测试模块之间的TCP建链失败，从而可以避免多用户测试时部分用户的业务数据的流量为0Mbps，从而提高了多用户测试场景的健壮性。
在本申请实施例中通过有线网络与多用户模块或待测终端连接的流量测试模块可以称为第一流量测试模块。示例性地，时钟同步模块与第一流量测试模块可以是部署在同一服务器/主机电脑中，也可以部署在不同的服务器/主机电脑中。
可选的，待测终端包括第二流量测试模块，第二流量测试模块用于测量来自服务器/主机电脑的业务数据的流量。可选的，辅助终端包括第三流量测试模块，第三流量测试模块用于测量来自服务器/主机电脑的业务数据的流量。
在一种实现方式中，该测试装置还包括干扰模块，该干扰模块包括多个干扰AP，多个干扰AP用于与多用户模块中的多个辅助终端进行无线保真通信。
可选的，多个干扰AP的带宽、速率、竞争空口的参数、竞争空口的频度、信道、或信号强度中的至少一种参数是可配的/可调整的，可以模拟家庭、办公区、机场、火车站等场景的复杂干扰，多个干扰AP发出的WiFi干扰是冲突退让的，与真实的WiFi干扰相符。干扰AP的竞争空口的频度，可以理解为，干扰AP能够支持的最大的业务数据的流量。竞争空口的参数包括仲裁帧间隙数(arbitration interframe spacing numbe，AIFSN)、最小竞争窗口(minimum contention window)、最大竞争窗口(maximum contention window)、和传输机会(transmit opportunity)等参数。
