具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例提供的无线局域网系统的系统架构图，如图1所示，本实施例提供的无线局域网(Wireless Local Area Networks，简称WLAN)系统包括无线接入点(Access Point，简称AP)和工作站(Station，简称STA)，STA通过无线AP接入以太网。该基于WIFI的无线局域网系统基于IEEE 802.11系列标准实现，是利用高频无线射频(如2.4GHz，5GHz，60GHz等频段的无线电磁波)作为传输介质的无线局域网。
其中，无线AP是用于无线网络的无线交换机，也是无线网络的核心。无线AP是移动计算机用户进入有线网络的接入点，主要用于宽带家庭、大楼内部以及园区内部，典型距离覆盖几十米至上百米。在无线路由器、部分数字用户线用户终端设备(Digital Subscriber Line，Customer Premise Device，简称DSL CPE)，终端设备(Cable Modem，简称CM)，光网络单元(Optical Network Unit，简称ONU)中都可以集成无线接入点AP。
STA在WLAN中一般为客户端，可以是装有无线网卡的计算机，也可以是有WiFi模块的智能手机、智能电视、PAD、影视盒子等。STA可以是移动的，也可以是固定的。
在无线AP与STA进行通信时，无线AP可从以太网获取下行报文，然后将该下行报文发送给STA，STA也可以将上行报文发送给无线AP，然后STA将该上行报文发送到以太网。本实施例所涉及的报文主要针对无线AP从以太网接收的下行报文。
图1仅示出了无线局域网系统的一种系统架构，对于其它的系统架构，只要涉及无线AP与STA连接的，都属于本发明的保护范畴。对于其它的系统架构，本实施例此处不再赘述。
基于无线局域网系统中存在无法定位WiFi网络的故障点的问题，本发明实施例提供一种获取报文处理延迟的方法，通过该方法可以获取无线AP在 处理数据报文时的处理延迟，根据该处理延迟，可以判断WiFi网络的故障是否由上述系统架构中的AP产生。下面采用详细的实施例进行说明。
图2为本发明实施例提供的获取报文处理延迟的方法流程图。图3为本发明提供的数据报文的处理场景示意图。如图3所示，本实施例的执行主体为无线AP中的处理器，如图2所示，该方法包括：
步骤201、接收报文通知消息，并获取接收所述报文通知消息的时间，作为第一接收时间，所述报文通知消息用于指示启动数据报文的处理。
结合图3，广域网的数据报文从无线AP的广域网(WideAreaNetwork，简称WAN)接口进入无线AP中，该广域网的数据报文例如可以为以太网的数据报文。该WAN接口用于将无线AP接入广域网，WAN接口可以使用以太网接入、数字用户线路(Digital Subscriber Line，简称DSL)接入、同轴接入(例如，有线电缆数据服务接口规范(Data Over Cable Service Interface Specifications，简称DOCSIS)，多媒体同轴电缆联盟MoCA)，光纤接入，电力线通信接入等。
WAN接口在接收到数据报文之后，将该数据报文传输到以太网交换机(LAN switch，简称LSW)中，即LSW通过WAN接口从广域网接收数据报文。LSW在接收到数据报文之后，对数据报文进行交换处理。在交换处理完成后，LSW将该数据报文存储到LSW对应的存储空间中，然后LSW向处理器发送报文通知消息。
处理器接收LSW发送的报文通知消息，并获取接收报文通知消息的时间，作为第一时间。该报文通知消息用于指示启动数据报文的处理，代表处理器需要对数据报文启动处理流程。
步骤202、根据所述报文通知消息的指示，获取数据报文，并对所述数据报文进行处理，得到处理后的数据报文，其中，所述处理包括如下中的至少一种：对所述数据报文进行存储、对所述数据报文进行转换、对所述数据报文进行调度、对所述数据报文的空口发送机会进行竞争。
处理器在接收到报文通知消息之后，根据该报文通知消息的指示，从LSW的存储空间中获取该数据报文，然后对该数据报文进行处理，得到处理后的数据报文。对该数据报文进行处理，主要包括如下的至少一种处理。下面分别进行详细说明。
对数据报文进行存储。处理器从LSW的存储空间中获取该数据报文，并将该数据报文存储到无线AP的存储器中。
对数据报文进行转换。处理器将存储器中存储的数据报文进行转换，例如将以太网的数据报文转换成WIFI报文，即802.11协议所规定的报文，或者还可以对该数据报文进行聚合、分片等转换处理。
对数据报文进行调度。由于存储器中可能会有多个数据报文需要发送，因此处理器需要对存储器中存储的数据报文进行调度，以决定各数据报文的发送顺序。
对数据报文的空口发送机会进行竞争。处理器按照WiFi的竞争机制，例如载波检测多路访问/冲突避免协议(CSMA/CA)的竞争机制，来对空口发送机会进行竞争。即竞争数据报文发送时所需要的信道。
本领域技术人员可以理解，上述的对数据报文的处理，可以上述的处理过程均执行，也可以执行其中的几个处理流程。对于具体的执行过程，本实施例此处不做特别限制。在上述的处理均执行时，可以按照存储、转换、调度、竞争的过程来执行。
步骤203、向STA发送所述数据报文，并获取接收所述STA返回的确认报文的时间，作为第二接收时间。
处理器在对数据报文处理完成后，通过WIFI芯片向STA发送该数据报文。其中，WIFI芯片上可以承载WIFI接口，可通过WIFI接口向STA发送数据报文。
STA在接收到该数据报文之后，会针对该数据报文向无线AP回复确认报文，以指示该数据报文接收成功。然而，当由于一些传输错误，有可能确认报文丢失，或者确认报文指示STA收到的数据报文出错，那么无线AP确认数据报文发送失败，无线AP启动数据报文的重传机制，此时会对该数据报文重新执行调度、竞争等处理流程，然后进行重传，若数据报文重传失败，则确认报文发送失败，将该数据报文丢弃，并记录丢弃的数据报文，从而获取对丢包率。
进一步地，在计算丢包率时，根据丢失的报文，统计报文丢失统计量。例如报文总数量，总流量，丢包数量，丢包率等，丢包率可以为各个时间区间内的丢包率。
本领域技术人员可以理解，本实施例获取的确认报文可以为首次发送数据报文对应的确认报文，也可以为重传过程对应的确认报文。
在无线AP的WIFI芯片接收到该确认报文之后，记录接收该确认报文的时间，并将该接收确认报文的时间发送给处理器，处理器在获取到该接收确认报文的时间后，将该时间作为第二时间。
步骤204、根据所述第一接收时间和所述第二接收时间，计算出所述数据报文的处理延迟。
处理器在得到第一接收时间T1和第二接收时间T2之后，就可以计算得到数据报文的处理延迟。由于第一接收时间为接收报文通知消息的时间，即准备开始处理数据报文的时间。因此，通过第一接收时间和第二时间计算得到的处理延迟，主要包括了处理器在处理过程的处理延迟以及往返延迟，该处理延迟即处理器在进行存储、转换、调度、竞争等过程的延迟。
在计算处理延迟时，可以通过T2-T1的方式来获取处理延迟，也可以通过T2-T1的各种变形方式来获取处理延迟，例如aT2-bT1的形式，或者
Figure PCTCN2016098446-appb-000001
的形式，其中a、b为延迟系数。
本领域技术人员可以理解，本实施例在此仅以一个数据报文为例，来说明数据报文的延迟。在具体实现过程中，无线AP向STA会发送多个数据报文，此时，无线AP可以针对预设数量的数据报文的处理延迟进行统计。从而可以获取平均延迟，最大延迟，最小延迟，延迟在各个时间区间内的统计参数等。
本实施例提供的获取报文处理延迟的方法，通过接收报文通知消息，并获取接收报文通知消息的时间，作为第一接收时间，该第一接收时间即为处理数据报文的起始时间，在获取到第一接收时间后，根据报文通知消息的指示，获取数据报文，并对数据报文进行处理，得到处理后的数据报文，然后向STA发送数据报文，并获取接收STA返回的确认报文的时间，作为第二接收时间，该第二接收时间即为确认数据报文发送成功的时间，根据第一接收时间和第二接收时间，可以计算出数据报文的处理延迟，根据该处理延迟可以监控无线AP的服务质量，在网络性能不达标时，若该处理延迟的值超过预设值，则说明无线AP出现故障，从而可以定位故障发生的设备为无线AP。
下面采用详细的实施例，来说明上述实施例中处理器对数据报文进行转换处理以及获取第二接收时间的具体实现过程。
在具体实现过程中，从无线AP的WAN接口进入的数据报文，与从WIFI芯片发送的数据报文，具有多种对应关系，可以为一一对应的关系，也可以将WAN接口接收的数据报文分片成多个报文从WIFI芯片发送，也可以将WAN接口接收的多个数据报文聚合成一个报文从WIFI芯片发送。
在一个具体的例子中，例如，在该无线局域网基于802.11协议实现时，该数据报文在通过WIFI芯片发送给STA时，需要转换为802.11协议规定的报文。此时，二者对应的关系可以为一一对应的关系，也可以将WAN接口接收的报文分片成多个802.11协议规定的报文，也可以将WAN接口接收的多个报文聚合成一个802.11协议规定的报文。
二者的对应关系不同，则对应的获取报文的发送信息的过程不同，下面分别进行详细说明。
一种可行的实现方式，从WAN接口接收的数据报文与从WIFI芯片发送的数据报文，二者的对应关系为一对一的关系。此种实现方式的具体实现过程，可参见图2所示实施例，本实施例此处不再赘述。
另一种可行的实现方式，图4为本发明实施例提供的数据报文传输的流程示意图一。如图4所示，该方法包括：
步骤401、对数据报文进行分片处理，得到多个第一数据报文；
步骤402、向STA依次发送多个第一数据报文；
步骤403、获取接收STA返回的各第一确认报文的时间；
步骤404、判断STA是否针对每个第一数据报文返回第一确认报文；若是，则执行步骤405，若否，则执行步骤406；
步骤405、将接收最后一个第一确认报文的时间，作为第二接收时间；
步骤406、确定数据报文发送失败。
在本实施例中，处理器在从LSW的存储空间中获取该数据报文之后，如果该数据报文的大小大于WIFI接口对应的最大传输单元(Maximum Transmission Unit，MTU)，则处理器会将该数据报文进行分片处理，得到多个第一数据报文。然后处理器通过WIFI接口向STA依次发送多个第一数据报文，并接收STA针对各第一数据报文返回的第一确认报文。
具体地，图5为本发明实施例提供的数据报文传输过程示意图一，请结合图5所示，处理器在将该数据报文进行分片处理之后，得到三个第一数据报文。处理器通过WIFI接口向STA依次发送第一数据报文。
例如，无线AP向STA发送第一数据报文10，当STA接收成功之后，STA向无线AP返回第一确认报文ACK；无线AP向STA发送第一数据报文20，当STA接收成功之后，STA向无线AP返回第一确认报文ACK；无线AP向STA发送第一数据报文30，当STA接收成功之后，STA向无线AP返回第一确认报文ACK。至此，无线AP将该数据报文全部成功发送给STA。
本领域技术人员可以理解，在此过程中，针对任一第一数据报文，若该第一数据报文首次发送失败，则会开启重传机制，将该第一数据报文重传给STA，在重传成功时，将获取到重传过程对应的第一数据报文的第一确认报文；当重传失败后，则该第一数据报文发送失败。
在该数据报文的传输过程结束后(数据报文的传输过程包括重传过程)，获取接收STA返回的各第一确认报文的时间，并判断STA是否针对所有的第一数据报文返回第一确认报文，若是，则将接收最后一个第一确认报文的时间，作为第二接收时间。本领域技术人员可以理解，该最后一个确认报文可以为重传过程的确认报文。
在图5所示实施例中，第一数据报文30对应的第一确认报文ACK为最后一个第一确认报文，则将接收第一数据报文30对应的第一确认报文的时间作为第二接收时间。若STA没有针对所有的第一数据报文返回第一确认报文，则认为该数据报文发送失败。
本实施例对数据报文进行分片，得到多个第一数据报文，然后将该第一数据报文依次发送给STA，然后根据各第一确认报文的接收时间来确定第二接收时间，实现了针对分片报文也可以得到第二接收时间，从而在无线AP在执行报文分片处理的操作时，也可以监控无线AP的服务质量。
又一种可行的实现方式，图6为本发明实施例提供的数据报文传输的流程示意图二。如图6所示，该方法包括：
步骤601、将数据报文与其它数据报文进行聚合处理，得到第二数据报文；
步骤602、向STA发送第二数据报文；
步骤603、获取接收STA返回的第二确认报文的时间；
步骤604、判断第二确认报文中是否包括用于指示该数据报文接收成功的接收信息，若是，执行步骤605，若否，执行步骤606；
步骤605、将接收第二确认报文的时间，作为第二接收时间；
步骤606、确定该数据报文发送失败。
在本实施例中，处理器在从LSW的存储空间中获取该数据报文之后，如果该数据报文的大小小于WIFI接口对应的最大传输单元(Maximum Transmission Unit，MTU)，则处理器会将该数据报文与其它数据报文进行聚合处理，得到第二数据报文。然后处理器通过WIFI接口向STA发送第二数据报文。
具体地，图7为本发明实施例提供的数据报文传输过程示意图二，请结合图7所示，处理器对数据报文10、数据报文20以及数据报文30进行了聚合处理，即对三个数据报文的数据部分进行了聚合处理，然后加上报文头(未示出)形成了第二数据报文。在本实施例中为了便于说明，在图7中示意性的示出了数据报文10、数据报文20以及数据报文30聚合成了第二数据报文。
在聚合得到第二数据报文之后，无线AP向STA发送该第二数据报文，STA在接收到该第二数据报文之后，会向无线AP返回块确认报文BA。在该块确认报文中，包括用于指示该数据报文是否接收成功的接收信息。例如，若数据报文10和数据报文30接收成功，则在该块确认报文中，包括用于指示该数据报文10和数据报文30被接收成功的接收信息。可选地，还可以包括数据报文20被接受失败的接收信息。
对于数据报文20，则对该数据报文20进行重传处理，在重传处理过程中，同样会对数据报文20进行聚合处理。本领域技术人员可以理解，重传对应重传失败和重传成功两种情况。若重传成功，则重传过程对应的块确认报文中包括用于指示数据报文20被接收成功的接收信息。
因此，处理器在通过WFII接口接收到第二确认报文之后，判断第二确认报文中是否包括用于指示该数据报文接收成功的接收信息，对于数据报文10和数据报文30，则判断结果为是，此时将接收第二确认报文(块确认报文BA)的时间作为为数据报文10和数据报文30的第二接收时间。对于数据报文20，若该数据报文20重传失败，则该第二确认报文中包括用于指示数据报文20 被接收失败的接收信息，由此确定数据报文20发送失败。
本实施例对数据报文进行聚合处理，得到第二数据报文，然后将该第二数据报文发送给STA，然后根据第二确认报文的接收时间来得到第二接收时间，实现了针对聚合报文也可以得到第二接收时间，从而在无线AP在执行报文聚合处理的操作时，也可以监控无线AP的服务质量。
本领域技术人员可以理解，在上述图4至图7所示的实施例中，各确认报文的接收时间与图2实施例类似，即由WIFI芯片来记录各确认报文的接收时间，然后由WIFI芯片将各接收时间发送给处理器，由处理器根据各接收时间，来确定第二接收时间。

可选地，该WIFI接口85具体可包括基带电路851、射频电路852以及天线853，实现数据报文的发送。存储器84可能包含高速RAM存储器，也可能还包括非易失性存储NVM，例如至少一个磁盘存储器，存储器84中可以存储各种程序，用于完成各种处理功能以及实现本实施例的方法步骤。存储器84中也可以存储处理器84从以太网交换机82中获取的数据报文。
