一种网络加速方法、电子设备、芯片系统及存储介质
本申请要求于2021年11月18日提交国家知识产权局、申请号为202111373990.X、申请名称为“一种网络加速方法、电子设备、芯片系统及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及网络通信领域，尤其涉及一种网络加速方法、电子设备、芯片系统及存储介质。
背景技术
随着电子设备的智能化程度越来越高，电子设备中安装运行的应用软件也越来越多。很多应用软件在运行过程中需要通过网络与相应的服务器通信，以实现该应用软件提供的各种功能。
在用户使用应用软件的过程中，若该应用软件与相应服务器通信时使用的网络的质量较差，则会出现卡顿现象，影响用户的使用体验。目前，可以基于当前使用的网络的信号强度对当前使用的网络的质量进行评估，在当前使用的网络的质量较差的情况下，使用网络质量更好的网络进行网络加速。然而，这种以当前使用的网络的信号强度进行评估以进行网络加速的方式应用在视频播放场景中时，经常出现卡顿现象。
发明内容
本申请提供一种网络加速方法、电子设备、芯片系统及存储介质，降低电子设备播放视频时的卡顿现象。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种网络加速方法，该方法包括：
电子设备运行第一应用，第一应用包括视频流，电子设备通过电子设备的第一网卡传输视频流，视频流的速率分布包括连续的第一时间段、第二时间段和第三时间段，以及连续的第四时间段、第五时间段和第六时间段，其中，第一时间段、第三时间段、第四时间段和第六时间段的速率不为0，第二时间段和第五时间段的速率为0；
确定视频流在第一时间段中的第一部分的平均速率大于第一值，电子设备在第三时间段通过第一网卡传输视频流；
确定视频流在第四时间段中的第二部分的平均速率小于或等于第一值，电子设备在第六时间段通过电子设备的第二网卡传输视频流，第二部分的时长和第一部分的时长相等。
在通过信号强度判断网络质量时，为避免频繁唤醒其他网络切换导致功耗过高的现象，通常需要将信号强度阈值设置的较低，很可能当前网络不能满足数据流传输时也未切换到其他网络导致常常出现卡顿现象。本申请可以通过数据流的速率确定数据流的传输质量，相比于通过网络的信号强度确定网络质量，为更精确的判别方式。并 且，在提升传输质量时，不再依赖于通道级切换，而是采用流级切换；另外，在短视频场景中，会存在较长时间视频流的速率为0的情况(例如，上一视频缓存结束之后至下一视频缓存开始之前的时间段)，导致判断错误。本申请通过视频流的速率为0之前的一段时间的平均速率值判断视频流的传输质量，从而确定是否通过切换视频流到其他网络上的方式提升该视频流的传输质量，降低了视频播放过程中的卡顿现象的发生。
作为本申请第一方面的一种实现方式，第一时间段中的第一部分的结束时间和第一时间段的结束时间相同，第四时间段中的第二部分的结束之间和第四时间段的结束时间相同。
本申请中，为了能够更精确的确定速率为0的情况为缓存结束导致还是网络质量较差导致，可以取第一时间段中与第二时间段最近的一部分时间段。即取第一时间段中临近结束的一部分时间。
作为本申请第一方面的一种实现方式，视频流的速率分布中还包括速率不为0的第七时间段，该方法还包括：
确定第七时间段的平均速率小于或等于第一值，电子设备在第八时间段通过第二网卡传输视频流，其中，第八时间段的开始时间为第七时间段的结束时间，第七时间段的时长等于第一部分的时长。
当然，若第七时间段的平均速率小于或等于第一值，电子设备在第八时间段通过第一网卡传输视频流。本申请不仅可以应用在速率出现0的场景中，在速率不为0的场景中，也可以基于一段时间的平均速率值判断视频流的传输质量，从而降低卡顿现象的发生。
作为本申请第一方面的一种实现方式，电子设备通过电子设备的第一网卡传输视频流的过程中，该方法包括：
电子设备以均值周期获取视频流在均值周期内的平均速率，第一部分和第二部分的时长均大于均值周期的时长。
为了更精细的确定电子设备的视频流的传输质量，可以以小于均值周期(例如，500ms)的采集周期(例如，10ms、50ms、100ms等)获取视频流的速率。然后计算均值周期内的平均速率。以第一时间段内1个或多个均值周期内的平均速率替代第一时间段内的第一部分的平均速率。
作为本申请第一方面的一种实现方式，第一周期为均值周期中的一个周期，在第一周期内的平均速率大于第二值的情况下，第一周期内的周期传输质量为第一标识；
在第一周期内的平均速率小于或等于第二值、且不等于0的情况下，第一周期内的周期传输质量为第二标识；
在第一周期内的平均速率等于0的情况下，第一周期内的周期传输质量由历史均值周期内的周期传输质量的标识确定，其中，历史均值周期为第一周期之前的L个均值周期，第一周期位于第二时间段时，第一周期的历史均值周期中最早的一个均值周期的开始时间晚于第一时间段的开始时间，第一周期位于第五时间段时，第一周期的历史均值周期中最早的一个均值周期的开始时间晚于第四时间段的开始时间，其中，L为大于或等于1的自然数；
若连续M个均值周期内存在至少N个均值周期的周期传输质量为第二标识，则视频流的速率满足第一条件，否则视频流的速率满足第二条件，N为小于或等于M的整数，第一条件包括：视频流在第四时间段中的第二部分的平均速率小于或等于第一值，第七时间段的平均速率小于或等于第一值，第二条件包括：视频流在第一时间段中的第一部分的平均速率大于第一值。
作为本申请第一方面的一种实现方式，若历史均值周期为第一周期之前的一个均值周期，则第一周期内的周期传输质量的标识和第一周期之前的一个均值周期内的周期传输质量的标识相同；
若历史均值周期为第一周期之前的奇数个均值周期，则第一周期内的周期传输质量的标识为第一周期之前的奇数个均值周期的周期传输质量的标识的众数。
作为本申请第一方面的一种实现方式，视频流为具有第一特征的数据报文组成的数据流，第一特征由以下参数确定：数据报文的传输协议、传输端口和头部特征；
电子设备通过电子设备的第一网卡传输视频流的过程中，该方法包括：
电子设备获取第一特征对应的第一条件。
作为本申请第一方面的一种实现方式，电子设备通过电子设备的第二网卡传输视频流包括：
电子设备查看电子设备是否存储有备用网络；
在电子设备存储有备用网络的情况下，电子设备通过备用网络传输视频流，其中，备用网络包括第二网卡对应的第二网络。
本申请中，为了及时将满足对应的流质量评估条件的数据流切换到其他网络上，可以预先得到备用网络并存储，以在数据流的流质量参数满足对应的条件时，及时将满足对应的评估条件的数据流切换到备用网络。
作为本申请第一方面的一种实现方式，该方法还包括：
在电子设备未存储有备用网络的情况下，电子设备获取电子设备的第三网卡对应的网络的网络质量参数，第三网卡为电子设备中除第一网卡以外的其他网卡，网络质量参数包括以下至少一项：带宽、时延和空口速率；
在第二网卡为第三网卡中网络质量最优的网卡的情况下，电子设备将第二网卡对应的第二网络作为备用网络存储，网络质量由网络质量参数确定。
本申请中，也可以在未存储备用网络的情况下，先得到备用网络，然后下次判定数据流的流质量参数满足对应的评估条件的情况下，将数据流切换到备用网络上传输。
作为本申请第一方面的一种实现方式，电子设备将第二网卡对应的第二网络作为备用网络存储之前，该方法还包括：
电子设备唤醒第二网卡对应的第二网络。
作为本申请第一方面的一种实现方式，电子设备将第二网卡对应的第二网络作为备用网络存储之前，该方法还包括：
电子设备获取第一网卡对应的第一网络的网络质量参数；
相应的，电子设备将第二网卡对应的第二网络作为备用网络存储包括：
在第二网卡对应的第二网络的网络质量优于第一网卡对应的第一网络的网络质量的情况下，电子设备将第二网卡对应的第二网络作为备用网络存储。
本申请中，还需要确定除主用网络以外的其他网络中质量最优的网络的网络质量是不是优于主用网络的网络质量。在优于主用网络的网络质量的情况下，才会作为备用网络，避免将数据流从网络质量不符合当前数据流的要求的主用网络切换到网络质量更差的网络上。

在得到电子设备的主用网络之后，电子设备以第二周期监测主用网络的网络质量参数。

如图1所示的电子设备中可以安装运行多个应用，例如：社交通信应用、游戏应用、音视频应用和新闻应用等。这些应用可以通过所在的电子设备与其他电子设备(例如，应用对应的服务器)建立网络连接。
作为示例，应用A可以通过所在的电子设备中的无线网卡(也可记为Wi-Fi网卡)与应用A对应的服务器建立网络连接；应用A还可以通过所在的电子设备中的数据业务网卡与应用A对应的服务器建立网络连接。其中，无线网卡为支持无线局域网(Wireless Local Area Network，WLAN)上网的装置；数据业务网卡为支持分组无线服务(General packet radio service，GPRS)、增强型数据速率GSM演进技术(Enhanced Data Rate for GSM Evolution，EDGE)、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、高速下行链路分组接入(High Speed Downlink Packet Access，HSDPA)、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)、长期演进(Long Term Evolution，LTE)、第五代移动通信技术(5th Generation Mobile Communication Technology，5G)等移动通信技术上网的装置。
为了便于描述，可以将一个电子设备通过无线网卡与其他电子设备之间建立的网络通道记为Wi-Fi网络；将一个电子设备通过数据业务网卡与其他电子设备之间建立的网络通道记为蜂窝网络。
在实际应用中，不同应用(或者不同类别的应用)对所使用的网络通道的质量的要求不同。
参见图2，用户使用手机中的应用A(游戏类应用)玩游戏，其中，手机中的应用A通过手机中的无线网卡与应用A的服务器A建立网络连接，应用A和服务器A之间产生的数据流A(例如，游戏对战时产生的数据流)通过手机上的无线网卡和无线路由器之间的Wi-Fi网络传输。用户使用手机中的应用B(聊天类应用)聊天，其中，手机中的应用B通过手机的无线网卡与应用B的服务器B建立网络连接，应用B和服务器B之间产生的数据流B(例如，聊天时产生的数据流)通过手机上的无线网卡和无线路由器之间的Wi-Fi网络传输。
本申请实施例中将两个电子设备之间传输的数据序列记为数据流。在实际应用中，基于该数据流的应用场景，该数据流可以为视频流、音频流、下载流、会话流等。
若用户在同一位置(无线网卡和无线路由器之间的距离相同)、同一时间范围内(例如，半个小时以内)使用手机中的应用A和手机中的应用B，理论上Wi-Fi网络质量差异不大。然而，由于数据流A相比于数据流B在单位时间内产生的数据量更大，所以数据流A相比于数据流B对Wi-Fi网络的质量要求更高。用户使用应用B时比较顺畅，然而，用户使用应用A时可能出现卡顿现象，导致用户的体验较差。
因此，不同应用(或不同类别的应用)对网络通道的质量的要求是不同的。本申 请实施例可以针对不同应用(或不同类别的应用)设置不同的网络质量评估算法。在评估某个应用当前使用的网络通道不足以承载该应用产生的数据流的情况下(例如，用户携带手机远离无线路由器的位置等)，设置传输质量提升策略以加速数据流传输。
参见图3，在通过网络质量评估算法评估应用A的数据流A的传输质量较差的情况下，可以将数据流A从当前的Wi-Fi网络切换到其他网络通道。如图3所示，手机可以将数据流A切换到手机的数据业务网卡和基站之间的蜂窝网络上，以通过该蜂窝网络与服务器A传输数据流A。
另外，即使用户使用同一应用处理不同业务时，对该应用使用的网络通道的质量的要求可能也不相同。
参见图4，用户使用应用A进行下载时，产生下载流A1，用户使用应用A进行会话时，产生会话流A2。下载流A1和会话流A2均可以通过无线网卡和2.4GHz的无线路由器之间的Wi-Fi网络传输。
若用户在同一位置(无线网卡和无线路由器之间的距离相同)、同一时间范围内(例如，半个小时以内)使用手机中的应用A分别进行下载和会话，理论上，网络通道质量差异不大。然而，由于数据流A1相比于数据流A2在单位时间内产生的数据量更大，所以数据流A1相比于数据流B对网络通道的质量要求更高。用户使用应用A进行会话时比较顺畅，然而，用户使用应用A进行下载时可能觉得下载速率太慢，导致用户的体验较差。
因此，同一应用的不同业务场景对网络通道的质量的要求是不同的。本申请实施例可以针对同一应用的不同业务场景设置不同的网络质量评估算法。在评估应用当前使用的网络通道不足以承载该应用产生的某个数据流的情况下，设置传输质量提升策略以加速数据流传输。
参见图5，在通过网络质量评估算法评估应用A的数据流A1的传输质量较差的情况下，可以将数据流A1分配到多个网络通道上并行传输。如图3所示，手机上设置有无线网卡1，支持2.4GHz的收发；还设有无线网卡2，支持5.0GHz的收发；还设有数据业务网卡。数据流A1可能包括多个子数据流，可以将多个子数据流分为3组数据流：数据流A1-1，数据流A1-2和数据流A1-3。将3个数据流分别分发到3个网络通道上传输。
需要说明，图5中的无线路由器可以为同时支持2.4GHz的收发和5.0GHz的收发的一个无线路由器，还可以是分别支持2.4GHz的收发和5.0GHz的收发的两个路由器。
通过图3和图5可以理解，还可以设置不同的传输质量提升策略(例如，图3中的切换，图5中的并发)以加速数据流的传输，从而提升用户的体验。
本申请实施例中某个网络通道的网络质量的好(优)坏(差)或某个数据流在某个网络通道上的传输质量的好(优)坏(差)均可以通过一些参数进行评估。在具体实现时，可以设置一些条件，例如，在满足条件1时，认为评估结果为好(优)，在不满条件1时，认为评估结果为坏(差)；或者在满足条件2时，认为评估结果为坏(差)，在不满条件2时，认为评估结果为好(优)。本申请实施例网络质量和传输质量的评判条件不做限定。
鉴于上述图2至图5的描述，本申请实施例提供一种网络加速方法。该网络加速 方法中，开发人员可以预先针对不同应用(或不同类别的应用)设置不同的网络质量评估算法和不同的传输质量提升策略。
当然，实际应用中，也可以针对不同应用(或不同类别的应用)设置不同的网络质量评估算法和相同的传输质量提升策略；或者针对不同应用(或不同类别的应用)设置相同的网络质量评估算法和不同的传输质量提升策略。还可以针对同一应用的不同业务场景设置不同的网络质量评估算法和不同的传输质量提升策略。
当然，实际应用中，也可以针对同一应用的不同业务场景设置不同的网络质量评估算法，和相同的网络质量提升策略；或者针对同一应用的不同业务场景设置相同的网络质量评估算法和不同的传输质量提升策略。
鉴于上述描述，可以得到如表1所示的网络加速方法，该网络加速方法中，可以考虑为不同的应用类别和/或不同的业务场景设置网络加速策略。在设置网络加速策略时，可以采用不同的网络质量评估算法和/或采用不同的传输质量提升策略。

以表1中的网络加速方法9为例，可以为不同类别的应用在不同业务场景(例如，通过应用的数据流的特征确定)下设置不同的网络质量评估算法，在网络质量评估算法评估的网络质量较差(或用于评估网络质量的一些参数满足某个条件)的情况下，采用不同的网络质量提升策略实现网络加速。其他网络加速方法不再一一举例。
参见图6，为本申请实施例提供的一种网络加速方法的流程示意图。该流程示意图与上述表1中的网络加速方法9对应。
步骤A1，电子设备检测到应用A在前台运行。
在本申请实施例中，应用A可以是电子设备中任意能够联网使用网络的应用程序。电子设备检测到应用A在前台运行可以是电子设备检测到应用A开启后在前台运行，也可以是监测到应用A从后台切换到前台运行。
步骤A2，电子设备确定应用A是否支持网络加速。
在本申请实施例中，电子设备中存储有应用配置库，该应用配置库可以由开发人员预先设置，也可以由用户在使用电子设备的过程中设置或添加。该应用配置库中存储有支持网络加速的应用的标识。
电子设备检测到应用A切换到前台后，可以获得应用A的应用标识，并在应用配置库中查询是否存在应用A的应用标识，若存在应用A的应用标识则表示应用A支 持网络加速。
当然，上述确定应用A是否支持网络加速的方式仅用于举例。实际应用中，该应用配置库还可以存储多个应用标识，每个应用标识采用不同的字符表示该应用标识表示的应用是否支持网络加速。作为示例，可以采用“1”表示支持网络加速，采用“0”表示不支持网络加速。其他确定应用是否支持网络加速的方式不再一一举例。
步骤A3，在应用A支持网络加速的情况下，电子设备查询应用A的数据流特征，以得到应用A的数据流特征对应的网络质量评估算法。
在本申请实施中，设置不同业务场景一方面便于理解设置不同网络质量评估算法的作用；另一方面还可以基于不同业务场景确定采用何种网络质量评估算法。然而，实际应用中，不同业务场景产生的数据流的特征可能不同。因此，并不是必须确定应用A当前的业务场景，可以根据应用A当前的数据流的特征确定当前应该采用的网络质量评估算法。应用A的数据流的各种信息可以存储在应用A的流特征库中。
在具体实现时，电子设备的系统中存在Netfilter组件，通过该组件可以获取到特定应用标识对应的应用的数据流。
作为一种示例，若承载应用A的数据流网络通道为网络通道1，则Netfilter组件可以获取应用A在网络通道1上的数据流的报文。若承载应用A的数据流网络通道为网络通道1和网络通道2，则Netfilter组件可以获取应用A在网络通道1和网络通道2上的数据流的报文。
当然，实际应用中，也可以通过其他方式获取数据流的报文。获取的数据流的报文的集合为流特征库。
在通过应用的数据流的特征确定网络质量评估算法时，可以将应用的数据流的协议、端口和报文特征作为特征确定网络质量评估算法。其中，协议为应用传输数据流时的协议类型，端口为传输数据流时使用的端口，报文特征为应用传输数据流时的数据包的头部特征。
作为示例，某社交通信类应用在进行音视频通话时，数据流对应的数据包的头部特征为97开头，即data[0]＝97，传输数据包时采用UDP协议，并且使用8080端口传输数据包。在得到的数据流中，若某个数据流满足上述特征，则可以得到与该特征匹配的网络质量评估算法为：若5个周期(例如，每个周期为500ms)内连续3个周期内数据的时延超过300ms，或丢包率超过20％，则评估结果：卡顿。
上述确定网络质量评估算法的示例仅用于举例，实际应用中，还可以通过协议、端口和报文特征以外的其他特征确定网络质量评估算法。
当然，某个应用在实现某个功能时，可能产生多个数据流，若针对多个数据流的特征分别确定了网络质量评估算法，则采用对应的网络质量评估算法评估对应的数据流的传输质量。
作为示例，某个应用在实现某个功能时，可能产生数据流1、数据流2和数据流3。
根据数据流1的特征确定网络质量评估算法1，并确定数据流1是否满足算法1设置的传输质量提升条件；
根据数据流2的特征确定网络质量评估算法2，并确定数据流2是否满足算法2设置的传输质量提升条件；
数据流3的特征并未满足任一可确定网络质量评估算法的条件，则无需评估数据流3的传输质量，也不需要提升数据流3的传输质量。
步骤A4，电子设备判断应用A的数据流的相关参数是否满足算法设置的传输质量提升条件。
需要说明，实际应用中，可以根据算法模型以及应用A的数据流的相关参数得到应用A的数据流的传输质量评估结果(例如，可以得到质量分数或质量等级)，根据传输质量评估结果确定是否需要提升该数据流的传输质量。当然，实际应用中，该算法可以预先设置确定需要提升该数据流的传输质量的条件，在满足该条件的情况下，获取传输质量提升策略，并执行传输质量提升策略。
如步骤A3中的网络质量评估算法的举例，需要得到应用A的各个数据流的时延、丢包率等。
如前，该应用A的流特征库中存储该应用A的数据流的各种信息，例如，应用使用当前网络时采用的协议的协议特征，应用使用当前网络时传输的数据包的头部特征等。当然，还可以包括应用使用当前网络时的流量特征。
其中，应用的流量特征可以包括：上行速率、下行速率、流间隔时间、包间隔时间、包大小和流量分布等信息。当然，还可以包括上述信息中的部分信息，或上述信息以外的其他信息。
通过流量特征可以得到时延情况、丢包情况、下行速率、上行速率等。因此，这些流量特征可以作为网络质量评估算法的评估参数。当然，实际应用中，不同的网络质量评估算法获得的用于评估网络质量的参数可能不同，例如，可以包含上述参数中的一个或多个，还可以包含上述参数以外的其他参数。因此，可以根据网络质量评估算法的评估参数确定应用的流量特征包含的参数类别。
步骤A5，在应用A的数据流的相关参数满足算法设置的条件情况下，根据应用A的数据流特征确定传输质量提升策略。
如前，可以预先为不同应用的不同业务场景(由数据流的特征确定)设置不同的传输质量提升策略，多个传输质量提升策略存储在提升策略库中。当然，实际应用中，也可以设置数据流的特征与传输质量提升策略的对应关系，在确定数据流的特征之后，就可以得到与该数据流的特征对应的传输质量提升策略。通过数据流的特征就可以从提升策略库中查询到与该特征匹配的传输质量提升策略。
步骤A6，执行传输质量提升策略。
本申请实施例中，一个应用在某个业务场景下可以产生多个数据流。在实际应用中，若多个数据流中部分数据流的特征满足预先设置的需要提升传输质量的条件，则可以将满足预先设置的需要提升传输质量的条件的数据流切换到其他网络通道；当然，也可以将满足预先设置的需要提升传输质量的条件的数据流以及与该满足预先设置的需要提升传输质量的条件的数据流相关的数据流切换到其他网络通道，可以预先设置数据流之间的相关性，例如，可以将下载类应用中具有相同源地址和目的地址的多个下载流设置为相关的数据流，也可以将聊天类应用中具有相同源地址和目的地址的视频流和音频流设置为相关的数据流；还可以将该应用的全部数据流切换到其他网络通道。
作为另一示例，实际应用中，若多个数据流中部分数据流的特征满足预先设置的需要提升传输质量的条件，也可以将满足预先设置的需要提升传输质量的条件的数据流分配到电子设备支持的多个网络通道；也可以将满足预先设置的需要提升传输质量的条件的数据流以及与该满足预先设置的需要提升传输质量的条件的数据流相关的数据流分配到多个网络通道上。当然，还可以将该应用的全部数据流分配到电子设备支持的多个网络通道上。
作为另一示例，实际应用中，若多个数据流中部分数据流的特征满足预先设置的并发条件，则可以首先将满足并发条件的数据流分配到多个网络通道上。在多个网络通道上的多个数据流中，存在某个数据流的特征满足预先设置的需要提升传输质量的条件的情况下，再将满足预先设置的需要提升传输质量的条件的数据流切换到质量更优的网络通道上。
作为另一示例，可以基于表2中的数据流的特征确定相应的网络质量评估算法和相应的传输质量提升策略。

其中，表2中的com.tencent.mm可以为微信包名，com.tencent.tmgp.sgame可以为王者荣耀包名。数据流的特征均可以为协议、端口和报文特征。表2中一个条目可以为一个应用的一个业务场景设置的数据流的特征条件、网络质量评估算法和网络质量提升策略。另外，表2仅列举了部分应用的部分业务场景对应的协议、端口和报文特征，且仅用于示例。
表2中的网络质量评估算法和传输质量提升策略仅用于举例，在实际应用中还可以采用其他不同的确定网络质量评估算法的方式和采用不同的传输质量提升策略。传 输质量提升策略中“切换”可以表示上述实施例中的任一形式的切换；“并发”可以表示上述实施例中的任一形式的并发。
作为另一示例，手机淘宝应用在浏览商品文字图像和观看商品视频业务场景时，可以仅将评估网络质量较差的流切换到其他网络，也可以在质量较差的流的个数(或比例)大于预设值(或预设比例)的情况下，将该应用下的所有流均切换到其他网络。
例如，该应用在某个业务场景下可能产生10个流，若仅有1个流或2个流的质量较差，则将质量较差的流切换到其他网络，若有3个或以上的流的质量较差，则将该应用下的全部流(10个流)全部切换到备用网络。
另外，在具体实现时，可以为不同的应用设置不同的应用标识，可以在数据流的特征满足特征条件时，得到网络质量评估算法设置的提升传输质量的条件，在数据流的相关参数满足提升传输质量的条件时，获得传输质量提升策略，并执行传输质量提升策略。
在实际应用中，表2中仅列出了部分应用的部分数据流的特征，以及对应的网络质量评估算法和传输质量提升策略。在实际应用中，还可以采用其他网络质量评估算法和传输质量提升策略。作为示例，还可以采用表3中示例的网络质量评估算法。

当然，实际应用中，表3中的网络质量传输算法仅用于示例，实际应用中，还可以采用表3所示的网络质量传输算法以外的其他算法，本申请实施例对此不做限定。

作为本申请另一实施例，上述实施例中一个组件可以拆分为两个或多个组件，位于同一层级的两个或多个组件可以合并为同一组件。
作为示例，策略层的流级策略管理组件和流级路径管理组件可以合并为同一组件； 应用级策略管理组件和通道级路径管理组件可以合并为同一组件。
为对上述架构图具有更清晰的理解，参见图8，为本申请实施例提供的基于图7所示的各个组件实现的一种网络加速方法的时序图。
步骤B1，用户启动应用A或将应用A从后台切换到前台。
步骤B2，环境探测组件检测到应用A开启或应用A从后台切换到前台，获取应用A的标识。
步骤B3，环境探测组件将应用A的标识发送给应用级策略管理组件。
该应用的标识用于唯一识别该应用，可以和应用的包名具有一一对应的关系，也可以采用应用的包名。
步骤B4，应用级策略管理组件基于接收到的应用A的标识，从应用配置库中查询接收到的标识对应的应用A是否支持网络加速。从应用配置库中查询到的结果为：支持网络加速。
步骤B5，在查询结果为支持网络加速的情况下，应用级策略管理组件向流级路径管理组件下发用于表示应用A开启网络加速的信息。
在具体实现中，该消息可以携带应用A的标识。
步骤B6，流级路径管理组件向流量上报组件下发表示应用A开启网络加速的消息。
在具体实现时，该消息也可以携带应用A的标识，且步骤B6中发送的消息和步骤B5中发送的消息可以相同，也可以不同。
步骤B7，流量上报组件接收到表示应用A开启网络加速的信息之后，注册报文监听钩子。
该报文监听钩子可以监听应用A的数据流的相关信息，该相关信息为应用A的流特征库中存储的信息。该数据流中携带了承载该数据流的网络的路径信息。
在步骤B4之后，可以探测应用A当前使用的网络的路径以及定期检测应用A当前使用的网络的网络质量。
如前，可以通过报文监听钩子监听到的数据流确定应用A当前使用的网络的路径。
作为另一示例，还可以按照系统设置的在存在多个可用网络的情况下选择主用网络的逻辑判断应用A当前使用的网络的路径。
在实际应用中，若电子设备中设有2.4GHz频段的无线网卡1、5.0GHz频段的无线网卡2、运营商A的数据业务网卡1和运营商B的数据业务网卡2。则可以默认无线网卡1或无线网卡2中的一个为主Wi-Fi，另一无线网卡为副Wi-Fi；默认运营商A的数据业务网卡1和运营商B的数据业务网卡2中的一个为主卡，另一个数据业务网卡为副卡。
作为示例，2.4GHz频段的网络通道为主Wi-Fi网络，5.0GHz频段的网络通道为辅Wi-Fi网络，数据业务网卡1对应的网络通道为主蜂窝网络，数据业务网卡2对应的网络通道为辅蜂窝网络。
在主Wi-Fi网络可用的情况下，系统默认电子设备或前台应用当前的主用网络为主Wi-Fi网络，在主Wi-Fi网络不可用的情况下，系统默认电子设备或前台应用当前的主用网络为主卡蜂窝网络。在主卡蜂窝网络不可用的情况下，系统默认电子设备或前台应用当前的主用网络为副Wi-Fi网络，在副Wi-Fi网咯不可用的情况下，系统默 认电子设备或前台应用当前的主用网络为副卡蜂窝网络。
在应用A开启后在前台运行时，应用A按照上述规则使用主用网络；即使应用A在前台时，系统将应用A中的部分数据流切换到其他网络上，在应用A切换到后台后，应用A中的数据流恢复使用系统默认的主用网络；在应用A从后台切换到前台后，应用A继续使用系统默认的主用网络。
因此，本申请实施例中可以按照上述规则依次请求该电子设备中的每个网络：主Wi-Fi、主卡网络、副Wi-Fi和副卡网络等。直到请求到一个可用且质量满足要求的网络。该可用且质量满足要求的网络可以理解为应用A当前使用的网络。具体可参照步骤C1至步骤C8。
步骤C1，流级路径管理组件接收到应用级策略管理组件发送的用于表示应用A开启网络加速的信息之后，向通道级路径管理组件发送请求主用网络的信息。
通道级路径管理组件接收到该请求信息后，按照主Wi-Fi、主卡网络、副Wi-Fi和副卡网络的顺序依次请求，直到找到一条可用且质量满足要求的网络，该网络为应用A的主用网络。
步骤C2，通道级路径管理组件向网络探测组件发送主Wi-Fi的状态的请求信息，该请求信息用于请求主Wi-Fi的状态。
步骤C3，网络探测组件确定主Wi-Fi可用。
步骤C4，网络探测组件向通道级路径管理组件返回主Wi-Fi的状态：可用。
步骤C5，在通道级路径管理组件接收到主Wi-Fi的状态可用的情况下，向通道及应用质量评估组件发送主Wi-Fi的质量的探测请求，该探测请求用于探测主Wi-Fi的质量。
本申请实施例中，任一网络的网络质量可以通过网络质量参数确定，网络质量参数包括以下至少一项：带宽、时延和空口速率。
步骤C6，通道及应用质量评估组件在评估主Wi-Fi的质量后，将主Wi-Fi的质量监测结果返回给通道级路径管理组件。
在具体实现中，在步骤C3之后，即网络探测组件确定主Wi-Fi可用之后，还可以执行步骤D1。
步骤D1，网络探测组件向通道及应用质量评估组件发送主Wi-Fi的质量的监测消息，该监测消息用于请求通道及应用质量评估组件监测主Wi-Fi的网络质量。
步骤D2，通道及应用质量评估组件接收到该消息后，开始监测主Wi-Fi的网络质量，并返回主Wi-Fi的质量给通道级路径管理组件。
在主Wi-Fi的网络质量好(例如，网络质量参数在预设范围)的情况下，可以确定主Wi-Fi为应用A的主用网络，可以定期监测主Wi-Fi的网络质量。
需要说明，步骤D2中监测的为网络通道的质量，采用的监测算法和上述实施例中根据数据流的特征确定的网络质量评估算法不同。为了便于描述们可以将该步骤采用的监测算法记为算法A。
作为算法A的一个示例，可以根据该通道的时延、丢包率、带宽和速率等参数作为参考评估网络通道的质量。
按照步骤D1和步骤D2这种方式，通道及应用质量评估组件可以接收到步骤C5 发送的探测请求之前就开始监测主Wi-Fi的网络质量，从而可以快速得到主Wi-Fi的质量，在得到主Wi-Fi的质量之后，能够及时返回给通道级路径管理组件主Wi-Fi的质量监测结果。
在实际应用中，通道及应用质量评估组件接收到步骤D1发送的监测请求后，首次获得监测结果可能在接收到步骤C5发送的探测请求之前，也可能在步骤C5发送的探测请求之后。
步骤C7，在通道级路径管理组件确定主Wi-Fi的网络质量满足要求的情况下，将主Wi-Fi作为主用网络的路径发送给流级路径管理组件。
步骤C8，流级路径管理组件存储主Wi-Fi的路径为主用网络的路径。
作为本申请另一示例，若步骤C3中，网络探测组件得到的主Wi-Fi的状态为不可用，网络探测组件不再执行步骤D1，相应的，通道及应用质量评估组件也不再执行步骤D2。通道级路径管组件接收到网络探测组件发送的主Wi-Fi不可用的消息后，也不再执行步骤C5，相应的，通道及应用质量评估组件也不再执行步骤C6。
通道级路径管组件接收到网络探测组件发送的主Wi-Fi不可用的消息后，继续按照步骤C2至步骤C6的方式(可以包括步骤D1和步骤D2，也可以不包括步骤D1和步骤D2)继续请求主卡网络(即当前请求的网络的下一个优先级网络)。若得到的结果为主卡网络可用且网络质量满足要求，则将主卡网络的路径作为主用网络的路径发送给流级路径管理组件，流级路径管理组件将主卡网络的路径作为主用网络的路径存储。同理，在主卡网络的网络质量满足要求的情况下，通道及应用质量评估组件也需要定期的评估主卡网络的质量。
在确定主用网络的过程中，需要循环执行步骤C2至步骤C6，直到得到所述电子设备的主用网络。该示例中，每一次循环执行步骤C2至步骤C6的过程中，探测的网络为一个电子设备的一个网卡对应的网络，在该过程中，每次请求的网络对应网卡可以记为第四网卡。
即电子设备按照电子设备的网卡的优先级顺序依次执行主用网络确定步骤，直到得到电子设备的主用网络；
其中，主用网络确定步骤包括：
电子设备获取第四网卡对应的网络的网络状态，第四网卡为所述电子设备的一个网卡；
在第四网卡的网络状态为可用的情况下，电子设备获取第四网卡的网络质量参数；在第四网卡的网络状态为不可用的情况下，结束本轮主用网络确定步骤，进入下一个优先级网卡的下一轮主用网络确定步骤；
在第四网卡的网络质量参数在预设范围内的情况下，将第四网卡作为电子设备的主用网络存储；在第四网卡的网络质量参数不在预设范围内的情况下，结束本轮所述主用网络确定步骤，进入下一个优先级网卡的下一轮主用网络确定步骤。
在实际应用中，可以由通道及应用质量评估组件确定网络的网络质量是否满足要求，在满足要求的情况下，定期评估该网络的网络质量；也可以由通道级路径管理组件接收到通道及应用质量评估组件发送的网络的质量监测结果后，确定网络的网络质量是否满足要求，在满足要求的情况下，向通道及应用质量评估组件发送请求消息， 以请求定期评估该网络的网络质量。通过上述方式通告级路径管理组件可以定期获取到当前承载应用A的数据流的网络的网络质量，并将获得的当前承载应用A的数据流的网络的网络质量发送到流级路径管理组件。
通过上述示例可以理解，按照系统设置的在存在多个可用网络的情况下选择主用网络的逻辑可以得到应用A当前使用的网络的路径。
在应用级策略管理组件执行步骤B4之后，即确定标识对应的应用A支持加速后，第一方面向通过流级路径管理组件向下层的流量上报组件传输应用A开启加速的消息，以使得流量上报组件注册报文监听钩子。第二方面还可以获得主用网络的网络路径以及主用网络的网络质量。第三方面通过流量感知组件向下层的流量上报组件传输启动数据流监控的消息，以使得流量上报组件通过注册的报文监听钩子监听应用A的数据流(具体可参照步骤B8)。
步骤B8，应用级策略管理组件向流量感知组件发送启动业务流监控的请求消息。
在具体实现时，应用级策略管理组件可以在执行完步骤B4之后同时执行步骤B5和步骤B8。应用级策略管理组件也可以在执行完步骤B4之后先执行步骤B5，在执行完步骤B5之后的预设时间(具体值可以根据实际情况设置)再执行步骤B8。
步骤B9，流量感知组件接收到步骤B8发送的请求消息后，向流量上报组件发送表示流量监控的消息。
步骤B10，流量上报组件接收到步骤B9发送的流量监控的消息后，将监听到的数据流上报给流量感知模块。
在步骤B7之后，流量上报组件中的报文监听钩子就开始监测数据流。接收到步骤B9发送的流量监控的消息后，将监听到的数据流上报给流量感知模块。并且，后续可以持续将监听的数据流上报给流量感知组件。
步骤B11，流量感知组件接收到流量上报组件上报的数据流，基于该数据流的特征确定网络质量评估算法。
需要说明，步骤B11中的网络质量评估算法和步骤D2中评估网络通道的算法不同。为了便于描述，步骤B11中的算法记为算法B。算法A为各个网络通道通用的算法，评估的是整个网络通道的网络质量。算法B为基于当前开启网络加速的应用的数据流的特征确定的算法，评估的是通过网络通道传输的满足预先设置的特征的数据流的传输质量。
步骤B12，流量感知组件基于网络质量评估算法开始评估应用A的各个数据流的传输质量得到评估结果。
需要说明，评估结果可以包括：优(例如，标识00)、可能卡顿(例如，标识10)和卡顿(例如，标识11)。
作为示例，上述表2中，为评估卡顿的条件，在实际应用中，还可以设置评估为可能卡顿的条件。
条件1：5个周期内连续3个时延超过300ms或丢包超过20％，则评估结果为卡顿。
条件2：5个周期内连续2个时延超过200ms或丢包率超过10％，则评估结果为可能卡顿。
若未出现上述两种情况，则评估结果为优。
基于上述理解，可以确定根据数据流的特征得到的网络质量评估算法不仅包含表2中限定的卡顿的判断条件，实际应用中，还可以包括可能卡顿的判断条件。
作为另一示例，可以预先设置条件1和条件2，该评估结果也可以包括：满足条件1，满足条件2，不满足条件1且不满足条件2。
在具体实现时，评估结果的具体形式不做限定。
步骤B13，流量感知组件向流级策略管理组件发送评估结果。
需要说明，该步骤发送的评估结果可以是表示卡顿、可能卡顿和优的标识，还可以携带数据流的特征(或特征标识)。
或者，该评估结果可以：满足条件1，满足条件2，不满足条件1且不满足条件2的标识，还可以携带数据流的特征(或特征标识)。
步骤B14，流级策略管理组件接收该评估结果后，在评估结果为可能卡顿(满足条件2)的情况下，确定请求备用网络。
作为另一示例，实际应用中，虽然满足条件1和条件2的情况下，传输质量提升策略均为：切换。但是，在满足条件2的情况下，向流级路径管理组件发送的是备用路径的请求信息，在满足条件1的情况下，向流级路径管理组件发送的是备用路径的切换信息。
采用上述设置可以在预判数据流的传输质量可能变差(例如满足条件2)的情况，提前确定好备用网络，并将备用网络唤醒，以便于在数据流的传输质量确实变差(例如满足条件1)的情况下，能够快速将传输质量差的数据流切换到备用网络上。这是由于数据流的传输质量通常是逐渐变差的，所以，在可能变差的情况下，先将选择好备用网络，并将备用网络唤醒，在数据流的传输质量确实变差的情况下，将传输质量较差的数据流切换到已经唤醒的备用网络上。这样，既能够快速响应数据流的切换，使得用户对数据流的切换无感知，还能够避免过早将备用网络唤醒导致的功耗高的问题。
步骤B15，流级策略管理组件在确定满足条件2的情况下，向流级路径管路组件发送备用路径的请求信息。
步骤B16，流级路径管理组件在确定当前不存在备用网络的情况下，向通道级路径管理组件发送备用路径的请求消息。
通道级路径管理组件接收到该备用路径的请求消息后，开始查找当前使用的主用网络以外的其他可用且质量最好的网络。具体可参照步骤B17至步骤B23的描述。
步骤B17，通道级路径管理组件向网络探测组件发送网络B的状态的查询请求。
在本申请实施例中，网络B可以是当前主用网络之外的其他任一网络。当前的主用网络可以记为网络A。网络B可以记为第三网卡对应的网络。
步骤B18，网络探测组件查询网络B的网络状态可用。
步骤B19，网络探测组件向通道级路径管理组件发送网络B的状态：可用。
步骤B20，通道级路径管理组件在接收到网络B的网络状态可用的情况下，向通道及应用质量评估组件发送网络B的质量的探测请求。
在实际应用中，为了快速得到网络B的网络质量，在步骤B18网络探测组件确定 网络B的网络可用的情况下，网络探测组件可以执行步骤B19和步骤E1。
步骤E1，网络探测组件向通道及应用质量评估组件发送监测网络B的质量的请求。
步骤E2，通道及应用质量评估组件接收到网络探测组件发送的监测网络B的质量的请求的情况下，开始采用A算法监测网络B的质量。
步骤B21，通道及应用质量评估组件在得到网络B的质量监测结果。
本申请实施例中，在评估网络通道的质量时采用网络质量参数，在评估数据流的传输质量时采用流质量参数。
步骤B22，通道级路径管理组件按照步骤B17至步骤B21的方式得到除主用网络以外的其他每个网络通道的状态和在状态可用的情况下得到可用的网络的网络质量。
步骤B23，通道级路径管理组件根据除主用网络以外的其他网络的状态和网络质量确定可用且网络质量最优的网络为主卡网络。当然，实际应用中，也可以设置一个范围，将第三网卡中网络质量参数在该范围内的网卡均作为备用网络。
需要说明，步骤E2检测网络B的质量时采用的算法和步骤D2采用的算法相同。
本申请实施例以确定质量最优(例如，信号强度最大，带宽更大等)的网络为备用网络，实际应用中。当然，实际应用中，还可以设置其他确定备用网络的条件。作为示例，还可以设置备用网络优先条件为：主用网络以外的可用、网络质量满足要求且不产生额外费用的网络作为备用网络，其中，不产生额外费用的网络可以为：Wi-Fi网络，流量套餐不限量的数据业务网络，或者流量套餐限量的数据业务网络但是当前使用流量小于当前月度计划流量(总流量/月度总天数×当前天数)。当然，备用网络可以是主用网络以外满足优先条件的网络中网络质量最好的一个。
在当前除主用网络以外的其他网络均不满足优先条件的情况下，再选择满足次优先条件的网络作为备用网络，其中，次优先条件为：主用网络以外的可用且网络质量满足要求的网络作为备用网络。当然，备用网络可以是主用网络以外满足次优先条件的网络中网络质量最好的一个。
在当前除主用网络以外的其他网络仍然不满足次优先条件的情况下，再选择主用网络以外可用的网络作为备用网络。当然，备用网络可以是主用网络以外可用的网络中网络质量最好的一个。
上述选择备用网络的方式仅用于举例，实际应用中，还可以为其他方式，在此不做限定。
步骤B24，在确定质量最优的网络为主卡网络之后，通道级路径管理组件向网络连接管理组件发送启用主卡网络的请求。
步骤B25，网络连接管理组件接收到主卡网络的启用请求后，将主卡网络从休眠状态切换为唤醒状态。
步骤B26，网络连接管理组件向通道级路径管理组件发送主卡网络已经被唤醒的消息。
步骤B27，通道级路径管理组件将当前确定的质量最优的主卡网络的路径和质量向流级路径管理组件发送。
如前，通道级路径管理组件可以定期得到电子设备的主用网络的网络质量。当然，通道级路径管理组件可以定期将得到电子设备的主用网络的网络质量发送至流级路径 管理组件。
因此，流级路径管理组件可以定期得到主用网络(主Wi-Fi)的网络质量。
步骤F1，流级路径管理组件已经存储了主用网络的网络路径，在接收到通道级路径管理组件发送的主卡网络的路径和网络质量之后，可以比较最新接收到的存储的主卡网络的网络路径对应的质量参数以及接收到的主卡网络的质量参数，确定出质量更好的网络路径。
在具体实现时，若质量更好的网络路径为预先存储的主用网络路径，则表示备用网络的质量更差，即使主用网络当前比较差，也没有切换的必要。则无需存储备用网络的网络路径。若质量更好的网络路径不为预先存储的主用网络路径，则表示备用网络的质量更好，则需要存储备用网络的网络路径，以备当前使用主用网络的数据流的传输质量更差的情况下，切换到备用网络上。
步骤F1的比较结果为主卡的质量更好的情况下，存储主卡的网络路径作为备用网络。
作为另一示例，在步骤B26之后，通道级路径管理组件可以请求定期监测主卡网络的网络质量，并定期发送给流级路径管理组件。
当然，实际应用中，可以定期监测主用网络以外的其他网络的网络质量，若网络质量最优的不再是当前存储的备用网络，则可以更换备用网络为当前的主用网络和当前的备用网络以外的其他质量更优的网络。若一个网络被作为备用网络唤醒，而后不再是备用网络也不是主用网络，则可以将该网络由唤醒状态再切换为休眠状态，以避免电子设备的功耗过大。
如前，流量上报组件在持续监控数据流，并持续上报监控到的数据流。
步骤B29，流量上报组件持续向流量感知组件上报监控到的数据流。
步骤B30，流量感知组件已经确定了各个数据流的网络质量评估算法(算法B)，并持续采用算法B得到评估结果。
步骤B31，流量感知组件持续将该评估结果发送给流级策略管理组件。
步骤B32，流级策略管理组件基于该评估结果，确定需要切换到备用网络。
作为示例，在满足上述示例中的条件1的情况下，确定切换到备用网络。
步骤B33，流级策略管理组件在确定切换到备用网络之后，向流级路径管理组件发送指令，用于表示切换到备用网络。
步骤B34，流级路径管理组件接收到切换备用网络的指令后，查看存储有备用网络的路径(主卡网络的路径)，则向流级策略管理组件发送切换到主卡网络的指令。
需要说明，流级策略管理组件存储有传输质量提升策略，因此，流级策略管理组件可以确定切换单条流，还是部分流还是全部流。在实际应用中，步骤B33中可以携带待切换的数据流的标识，同时，B34传输的指令中，也可以携带待切换的数据流的标识。两个步骤发送的指令中也可以不携带待切换的数据流的标识。
步骤B35，流级策略管理组件向策略执行组件发送指令，该指令携带数据流标识和主卡网络路径，其中，数据流标识为评估结果满足条件1的数据流标识，或者评估结果满足条件1的数据流以及相关的数据流标识，或者评估结果满足条件1的数据流所在的应用A的全部数据流标识。
步骤B36，策略执行组件执行将接收到的指令中携带的数据流标识表示的数据流切换到指令中携带的网络路径表示的主卡网络。
本申请实施例中，网络路径也可以为区分不同网络的网络标识。
作为本申请另一实施例，在实际应用中，网络质量可能并不是逐渐变差的，也可能是突发性变差。例如，步骤B14流级策略管理组件接收到的评估结果确定为切换备用网络，则步骤B15，流级策略管理组件向流级路径管理组件发送切换备用路径。然而，此时流级路径管理组件还未存储备用网络的路径。这种情况下，就需要先确定备用网络(步骤B16至步骤B27)，然后在确定备用网络的情况下，直接执行步骤B34，以将数据流切换到备用网络。
当然，在步骤B14流级策略管理组件接收到的评估结果确定为切换备用网络，此时流级路径管理组件接收到切换备用路径且已经存储备用网络的路径的情况下，则可以不再执行步骤B16至步骤F1，而是直接执行步骤B34，以将数据流切换到备用网络。
作为示例，应用A当前存在数据流C和数据流D，在一个周期，电子设备根据数据流C的传输质量评估结果(可能卡顿)请求备用路径并存储，数据流D的传输质量评估结果优。下一个周期，数据流C的传输质量评估结果为优，数据流D的传输质量评估结果确定切换备用路径。此时，电子设备已经存储了备用路径，则电子设备可以将数据流切换到备用网络上。
上述示例中，均以数据流的特征作为确定并唤醒备用网络的条件，实际应用中，还可以采用其他方式作为确定并唤醒备用网络的条件。即表2中还可以增加一列：确定并唤醒备用网络的条件。不同应用(或同一应用的不同业务场景)在前台运行时，确定并唤醒备用网络的条件可以相同也可以不同，也可以部分相同部分不同。
作为示例，针对每个应用的不同业务场景，可以设置与该应用该业务场景的数据流的流量特征相关的条件作为确定并唤醒备用网络的条件；针对所有应用的所有业务场景，可以设置相同的条件：信号强度逐渐变小等。该示例仅用于举例，并不造成任何限定。
作为本申请另一实施例，在图8所示实施例中，若应用A的全部流或部分流被切换到主卡上，在应用A从前台切换到后台后，应用A的全部数据流会回到系统默认的主用网络：例如主Wi-Fi。主用网络的确定方式可以参照上述实施例中的描述。应用A再次从后台切换到前台后，应用的全部数据流仍然在主用网络：主Wi-Fi，则继续实施本申请实施例提供的网络加速方法。
作为本申请另一实施例，在具体实现时，还可以采用其他方式获取应用A当前使用的主用网络的路径，并在确定应用A当前使用的主用网络的路径的情况下监测当前使用的主用网络的网络质量。
参见图9，为本申请实施例提供的另一网络加速方法的时序图。
流量上报组件在监听数据流时，可以确定承载该数据流的网络。由于预先设置了应用A再次从后台切换到前台后，应用的全部数据流仍然按照系统默认的方式确定当前使用的网络通道。所以，应用A再次从后台切换到前台或者应用A开启后，流量上报组件监听到的数据流所在的网络通道就为应用A的主用网络。因为，可以通过流量上报组件上报的数据流确定主用网络的路径。
在步骤B10之后，即在流量感知组件接收到上报的数据流后，可以执行步骤G1至步骤G6以存储主用网络的路径和质量监测结果。
步骤G1，流量感知组件根据上报的数据流确定承载该数据流的网络通道。
步骤G2，在确定网络通道(为主Wi-Fi)的情况下，流量感知组件向通道级路径管理组件发送用于表示主用网络为主Wi-Fi的消息。
步骤G3，通道级路径管理组件向通道及应用质量评估组件发送主Wi-Fi的质量探测请求。
步骤G4，通道及应用质量评估组件采用算法A定期监测主Wi-Fi的质量。
步骤G5，通道及应用质量评估组件向通道级路径管理组件返回主Wi-Fi的质量监测结果。
步骤G6，通道级路径管理组件将主Wi-Fi的路径和质量监测结果发送给流级路径管理组件。
步骤G7，流级路径管理组件存储主Wi-Fi的路径为主用路径，并存储主Wi-Fi的质量监测结果。
由于步骤G4中为定期监测主用网络(主Wi-Fi)的质量，因此，流级路径管理组件会定期接收到主用网络(主Wi-Fi)的质量。在电子设备执行步骤G1至步骤G7的过程中，电子设备也可以执行步骤B11和步骤B13。即不限定步骤G1和步骤B11的执行顺序。
若在流级策略管理组件执行B14时，根据数据流特征和评估结果确定需要请求备用网络，则继续执行后续步骤(步骤B15至步骤B36)，后续步骤可参照图8所示实施例的描述，在此不再赘述。
如前，确定主用网络的路径的情况下，在请求备用路径时，可以请求主用网络以外的其他网络。在定期监测主用网络的质量的情况下，在确定了备用网络后，可以将备用网络和主用网络进行比较，以在备用网络比主用网络的质量更优的情况下，将传输质量差的数据流切换到备用网络。当然，实际应用中，也可以在确定质量最好的备用网络的情况下，直接将传输质量差的数据流切换到备用网络。
参见图10，为本申请实施例提供的另一网络加速方法。
在步骤B4之后，执行步骤B8和步骤B9。
其中，流量上报组件在接收到步骤B9流量感知组件发送流量监控请求后被触发执行步骤H1，注册报文监听钩子。
在注册报文监听钩子后，该报文监听钩子可以监听应用A的数据流。在监听到应用A的数据流之后开始执行后续步骤。
需要说明，由于数据流中可以得到承载该数据流的网络通道，因此，流量感知组件可以确定应用A当前使用的网络通道，并可以将当前使用的网络通道的标识(主用网络)通过步骤B13发送到流级策略管理组件。
步骤B14，流级策略管理组件在根据数据流特征和评估结果确定请求备用网络。
步骤B15，流级策略管理组件将备用路径的请求信息发送到流级路径管理组件时，可以携带主用网络的标识(或主用网络的路径)。
步骤B16，流级路径管理组件向通道级路径管理组件发送备用路径的请求信息， 也可以携带主用网络的标识(或主用网络的路径)。
通道级路径管理组件接收到流级路径管理组件发送的携带主用网络的标识的请求信息后，可以依次请求电子设备支持的网络通道中除该主用网络以外的其他网络通道的状态，并在状态可用时，请求监测可用的网络通道的质量监测结果，最后将可用且质量最优的网络通道唤醒，并作为备用网络发送到流级路径管理组件。具体可参照步骤B17至步骤B27的描述。可参照上述实施例中的描述，在此不再赘述。
步骤28，流级路径管理组件在确定未存储主用网络的情况下，无需比较接收到的备用网络的质量和主用网络的质量，而是直接将接收到的网络通道作为备用路径存储。
后续步骤B29至步骤B36的描述具体可参照上述实施例中的描述。
作为本申请另一实施例，如表2所示，传输质量提升策略中还包括：并发。本申请实施例中，将上传下载类(存储类)应用进行大文件下载时，首先将数据流分到电子设备多个可用的网络通道上。在分到多个网络通道上后，若任一数据流满足网络质量评估算法规定的切换条件(例如，传输速率较慢)时，将满足网络质量评估算法规定的切换条件的数据流切换到其他质量更优的网络通道上。具体可参照图11所示实施例的描述。
步骤B11之前的步骤的描述可参照上述实施例中的描述，在此不再赘述。
步骤B11，流量感知组件在根据数据流特征确定需要将数据流分配到多个网络通道。
例如，表2中，在某上传下载类应用进行大文件下载时，需要将满足某特征的数据流分到多个网络通道上。
步骤J1，流量感知组件向通道级路径管理组件发送请求所有备用网络的信息。
步骤B17，通道级路径管理组件接收到所有备用路径的请求信息之后，开始对电子设备支持的网络通道中除主用网络以外的其他网络执行步骤B17至步骤B26的步骤。
需要说明的是，本申请实施例中，需要将主用网络以外的其他所有可用的网络通道唤醒。因此，在步骤B21之后，直接执行步骤B24请求唤醒当前可用的网络通道。按照上述过程将主用网络之外的每个可用的网络通道唤醒。
步骤B27，通道级路径管理组件将唤醒的每个备用网络的路径和质量监测结果(可以采用质量参数表示)发送到流级路径管理组件。
步骤B28，流级路径管理组件将每个备用网络的路径和质量参数存储。
需要说明，在电子设备执行步骤J1、B17至步骤B28的过程中，流量上报组件一直在上报数据流，同时流量感知组件一直向流级路径管理组件传输当前监听的数据流的标识。
步骤K3，在流级路径管理组件接收到主用网络的路径、备用网络的路径以及多个数据流的标识之后，将多个数据流分配到多个网络通道(主用网络和备用网络)上。
作为示例，若流级路径管理组件接收到1个主用网络的路径和3个备用网络的路径，接收到的数据流标识的个数为5个，则可以将5个数据流标识分到4个网络通道上。
在分配时，可以首先基于数据流个数和网络通道的个数均分的原则，在无法均分的情况下，分配给每个网络通道的数据流个数之间相差小于2。即步骤K3中的分配尽 量以均分的原则将多个数据流分配到多个网络通道上。
当然，实际应用中，也可以采用其他分配的原则，例如，根据各个网络通道的质量，将多个数据流分配到多个网络通道上，以使得质量更优的网络通道承载个数更多的数据流，质量较差的网络通道承载个数更少的数据流。其他分配的原则不再一一举例。
当然，也可以在该应用在前台运行时首次分配采用个数均分的原则，在首次之后的下一次分配(例如，可以设定分配周期)采用其他原则。
需要说明，步骤K3可以在流级策略管理组件中执行也可以在流级路径管理组件中执行。
若在流级路径管理组件中执行，则需要流级策略管理组件将数据流标识发送到流级路径管理组件。
若在流级策略管理组件中执行，则需要流级路径管理组件将多个网络路径发送到流级策略管理组件，并取消步骤K2。
步骤K4，流级路径管理组件将每个数据流标识对应的网络通道的路径发送给流级策略管理组件。
步骤K5，流级策略管理组件将接收到每个数据流标识对应的网络通道的路径发送给策略管理组件。
步骤K6，策略管理组件根据接收到的每个数据流标识和对应的网络通道的路径之后，将数据流标识对应的数据流切换到对应的网络通道上。
如前，报文监测钩子一直在监测数据流，同时也一直在上报监测到的数据流，参见步骤B29。
在将多个数据流从主网络通道分配到多个网络通道之后，报文监测钩子监测到的数据流承载各自对应的网络通道上。因此，流量感知组件接收到流量上报组件上报的数据流之后，可以根据监测到的数据流确定已经将多个数据流分配到多个网络通道上。
步骤K7，流量感知组件确定多个数据流已经分配到多个网络通道上后，可以采用各个数据流的特征得到与各个数据流对应的评估算法C。
步骤B30，流量感知组件根据确定各个数据流的评估算法C得到各个数据流的传输质量评估结果。
步骤B31至步骤B36可以参照上述实施例的描述，在此不再赘述。
本申请实施例中，在某个数据流的评估结果满足设置的评估算法规定的切换的条件下，需要将该数据流切换到其他质量更优的网络通道上。
如前，在确定并发的情况下，可以定期监测每个网络通道的网络质量，并将网络质量发送到流级路径管理组件。
步骤K8，流级路径管理组件根据定期接收到的各个网络通道的质量，将该数据流(不满足算法C设置的条件的数据流)切换到质量最优(例如，传输速率最快)的网络通道上。
该示例以不满足算法C设置的条件的数据流切换到质量更有的网络通道上。实际应用中，还可以设置其他切换方式。作为示例，切换到当前承载数据流的个数最少的网络通道上。或者，在用户的某个数据业务为不限流量套餐的情况下，将当前在Wi-Fi 网络上的不满足算法C设置的条件的数据流优先切换到该不限流量套餐的数据业务网络上。当然，在用户的数据业务均为限流量套餐的情况下，将当前在一个Wi-Fi网络上的不满足算法C设置的条件的数据流优先切换到另一个Wi-Fi网络上。
上述切换方式仅用于举例，实际应用中，可以根据实际情况设置切换方式，原则为：尽量不产生额外流量费用的前提下，最快传输当前应用下符合特定特征的数据流。
作为本申请另一实施例，参见图12，为本申请实施例提供的另一网络加速方法。
与图11所示的区别包括：
(1)触发流量上报组件注册报文监听钩子的方式不同，图11通过流级路径管理组件触发，图12通过流量感知组件触发。
(2)不再单独请求主用网络的路径，而是在流量感知组件根据数据流的特征确定需要先将当前的数据流分配到多个网络通道上的情况下，执行步骤J1，请求所有网络路径。
然后通过步骤B17至步骤B26将电子设备可用的网络通道唤醒，并将唤醒后的每个网络通道的路径和质量监测结果发送给流级路径管理组件。流级路径管理组件将数据流分配到多个网络通道上。步骤B28至步骤B36可以参照图11所示实施例的描述，在此不再赘述。图12中的网络C为电子设备支持的任一网络通道。
上述实施例中，均以流量上报组件中的报文监测钩子监听应用A的数据流为例进行说明，下面将描述报文监测钩子如何监听应用A的数据流，并将监听的数据流发送到给流量感知组件。
如前，电子设备的系统中存在Netfilter组件，通过该组件可以获取到特定应用标识对应的应用的数据流。流量上报组件可以通过调用Netfilter组件获取应用A的数据流的报文。具体实现时，流量上报组件上报给流量感知组件的信息不仅包括应用A的数据流的报文，还包括应用A的数据流的报文的一些统计信息。具体可参照图13所示实施例的描述。
参见图13，流量上报组件可以预先注册报文监听钩子(例如，nf_hook钩子函数)。
在流量上报组件调用Netfilter组件后，Netfilter组件上报应用A的数据流的报文，流量上报组件接收到Netfilter组件上报的数据流的报文之后，调用预先注册的nf_hook钩子函数。
该nf_hook钩子函数对接收到的数据流的报文进行以下操作：报文解析、查流表和报文分析等操作。
在进行解析时，可以查看该报文是否存在应用标识以及该报文的四元组(或五元组)，以得到解析结果。若存在应用标识，则可以确定该报文对应的应用。四元组中包括源IP、目的IP、源端口、目的端口；五元组中包括：源IP、目的IP、源端口、目的端口以及协议号。即通过报文的四元组或五元组携带了上述表2中数据流的部分特征。另外，报文(数据包)中本身也携带了头部特征。
在进行解析之后，根据解析结果查询流表，并更新流表的统计信息。流表中存储了各个应用中数据流的标识信息、以及各个数据流的统计信息。各个流的统计信息包括：接收到该数据流的报文数量、总字节数、错误包数量等。
实际应用中，各个流的统计信息可以根据网络质量评估算法中设置的参数确定。 因此，各个流的统计信息还可以包括其他信息，例如，根据时间点接收到的数据包的大小生成的该数据包所在的数据流随时间变化的流量分布信息。
当然，若流表中不存在某个数据流的标识信息或相关统计信息时，则可以在流表中增加该数据流的标识以及相关的统计信息。
在查流表并更新流表信息之后，则可以对报文进行分析。例如，过滤报文，从而得到全部或部分报文。
作为一种示例，该过滤过程可以是过滤某个数据流的心跳包报文。则经过过滤处理后，得到该数据流的心跳包报文。该过滤处理过程可以是：通过预先设置某些特征，将满足该特征的报文保留。即满足预先设置的某些特征的报文就为过滤后的报文。
其中，心跳包报文为按照一定的时间间隔存在于数据流中的报文。心跳包报文在固定位置(例如第6个字节)存在固定特征(例如0x64或0x65)。由于该心跳包报文为按照一定时间存在的报文，因为，可以基于该心跳包报文计算获得时延(例如，手机向服务器发送心跳请求报文开始，到手机接收到服务器反馈的心跳响应报文为止，总共经历的时间)。该时延信息用于确定该数据流是否满足上述表2中设置的提升传输质量的条件。
上述示例以过滤心跳包为例进行说明，实际应用中，还可以过滤处理以获得满足其它特征的数据包报文。
作为另一示例，过滤条件还可以包括：选择保留特定长度的数据包报文。在具体实现时，确定数据包报文的长度是否为预先设置的特定长度，若是，则保留该报文，若否，则将该报文过滤掉。
经过上述处理后，得到的过滤后的部分报文被存储在SKB队列中。
SKB队列中存储的数据流的报文上报时的策略包括：立即上报和定期上报。
若为立即上报，流量上报组件中的特定线程及时查看队列，将队列中的报文及时上报给流量感知组件。
若为定期上报，流量上报组件中设置了定时器，基于该定时器设置的时间以一定的周期查看SKB队列中的报文，将队列中的部分或全部报文上报给流量感知组件。
当然，实际应用中，SKB队列中存储的数据流的报文有些是需要立即上报的，有些是需要定期上报的。同样的原理，流量上报组件中的特定线程及时查看队列，将队列中的需要立即上报的报文及时上报给流量感知组件。流量上报组件中还设置了定时器，基于该定时器设置的时间以一定的周期查看SKB队列中的报文，将队列中的需要定期上报的报文上报给流量感知组件。
需要说明，上报报文时，还可以一定上报该报文相关的统计信息。
基于上述理解，流量上报组件并不是将Netfilter组件发送的所有报文均上报给流量感知组件。而是，将满足特定特征的报文(可以携带该满足特定特征的报文的统计信息)上报给流量感知组件。同时将上报与满足特征的报文相关的统计信息。
作为示例，若报文1和报文2均属于同一数据流的报文。接收到报文1后查流表时，根据报文1更新流表中关于该数据流的统计信息，然而，报文1不满足特定特征，所以报文1被过滤掉，不会上报给流量感知组件。接收到报文2后查流表时，根据报文2更新流表中关于该数据流的统计信息，报文2满足特定特征，所以报文2不会被 过滤掉，报文2会被上报给流量感知组件。即虽然上报了部分报文，然而，统计信息是基于该数据流下的所有报文得到的。
上述示例中的上报的报文以及相关的统计信息用于流量感知组件确定该报文表示的数据流的特征以及该数据流的传输质量。在描述流量上报组件如何上报数据流的报文给流量感知组件之后，下面将描述如何基于流量上报组件上报给流量感知组件的数据流报文确定表2中设定数据流的特征条件、网络质量评估算法设置的提升传输质量的条件。
作为示例，相同四元组(源地址，源端口，目的地址，目的端口)的报文(数据包)同属一条数据流。若通过网络通道传输了多个具有相同四元组的报文，则多个具有相同四元组的报文同属于一个数据流，也可以理解为：一个数据流中可以存在多个报文。同时，一个数据流下的报文携带该报文在数据流中的序列号。由于这些报文具有相同的特征，可以根据该相同的特征生成该报文所属的数据流的标识，作为示例，可以根据报文的四元组生成该报文所属的数据流的标识。
流量上报组件接收到报文之后，可以根据报文携带的应用标识确定该报文所属的应用。还可以根据该报文的四元组生成该报文所属的数据流的标识。
当然，流量上传组件将报文上传到流量感知组件之后，流量感知组件也可以基于接收到的报文确定所属的应用的标识和所属的数据流的标识。流量上报组件可以根据报文的五元组中的协议号确定数据流特征中的协议，通过四元组或五元组中的目的端口可以确定数据流特征中的端口。通过报文的头部特征可以确定数据流特征中的报文特征。即，基于流量上报组件上报的报文可以确定该报文所在的数据流的特征。
当然，上述数据流的特征的确定方式仅用于举例，实际应用中，还可以通过其他方式确定报文所在的数据流的特征。
在电子设备能够确定接收到的报文所属的数据流的特征之后，就可以基于该数据流的特征确定对应的网络质量评估算法设置的提升传输质量的条件。
当然，实际应用中，为了确保得到的网络质量评估算法设置的提升传输质量的条件准确，还可以增加限定条件：应用的标识，即根据应用的标识和数据流的特征共同确定对应的网络质量评估算法设置的提升传输质量的条件。
在确定了网络质量评估算法设置的提升传输质量的条件之后，该网络质量评估算法设置的提升传输质量的条件仅用于评估具有相同数据流特征(也可以增加相同应用标识和/或相同数据流标识)的数据流的传输质量。
在评估传输质量时，可以采用如下参数中的一个或多个：时延、丢包率、是否存在响应和速率。
如前，可以通过某个数据流下的心跳包确定时延。由于报文中携带了该报文在数据流中的序列号，因此，可以根据该序列号确定丢包情况。通过上述示例中的统计信息中报文总数确定是否下行无响应，作为示例，连续两个周期内接收到的报文总数相同，则确定下行无响应。通过上述示例中的统计信息中的总字节数确定传输速率，作为示例，上一周期和本周期接收到的总字节数的差值与周期的比值为本周期下行速率。
当然，上述参数的确定方式仅用于举例，在实际应用中，还可以通过其他方式确定上述参数。
上述示例中的主用网络可以记为第一网卡对应的第一网络，备用网络可以记为第二网卡对应的第二网络。
如前所述，在流量感知组件对数据流的传输质量进行评估时，可以判断数据流的相关参数(例如，时延、丢包率或下行速率等)是否满足表2中的网络质量评估算法设置的提升传输质量的条件。然而，基于表2中网络质量评估算法设置的提升传输质量的条件通常出现误判的情况。
作为示例，用户使用短视频类应用时，若用户刷到某短视频，该应用开始通过网络通道下载该短视频并缓存已经下载的该短视频的部分数据帧；该应用从缓存中获取该短视频的数据帧并开始播放。若该短视频的播放时长为15秒，以用户刷到该短视频为时间起点，从时间起点开始至第2秒，单位时间的下载速率会快速增大；从第2秒至第5秒，单位时间的下载速率会快速降低至0；从第5秒至第15秒播放结束，单位时间的下载速率维持0。
若采用上述表2中的网络质量评估算法设置的传输质量提升策略的条件，例如，表2中抖音应用的短视频业务场景设置的网络质量评估算法，该网络质量评估算法中若连续的多个周期的时延超过350ms或多个连续的周期的下行速率(均值)小于51kb/s。则表示数据流的传输质量较差，需要将当前数据流切换到其他质量更优的网络通道，以提高当前数据流的传输质量。上述示例中，在第5秒至第15秒期间，连续多个周期内的速率(均值)均为0，可能会判定当前数据流满足网络质量评估算法设置的提升传输质量的条件，即认为当前数据流在当前网络通道上的传输质量较差，需要将该数据流切换到其他网络通道上。
然而，在具体应用中，在第5秒至第15秒期间，该应用的数据流所在的网络通道的网络质量并不差，只是当前没有从其他电子设备下载数据流的需求，所以连续多个周期内的速率均为0。因此，表2中网络质量评估算法设置的提升传输质量的条件将不再适用。
鉴于此，本申请实施例提供另一种网络质量评估算法，该网络质量评估算法可以评估视频流的传输质量。为了便于描述，可以将后续应用于短视频应用中短视频业务场景下的数据流的网络质量评估算法记为算法E。
在具体实现时，可以通过以下特征确定该数据流是否适用于采用算法E作为评估该数据流的网络质量评估算法。特征如下：采用http协议、通过get向服务器请求视频内容、且get数据包中携带mp4字段。即捕获到的携带有mp4字段的http get请求包对应的数据流为适用于本申请实施例提供的算法E。
参见图14，为本申请实施例提供的网络通道质量较好时，短视频类应用的数据流的速率特点。视频流的速率呈周期分布，每个周期包括速率不为0的时间段和速率为0的时间段。
例如，图14中，视频流的速率分布包括：连续的第一时间段、第二时间段和第三时间段，其中，第一时间段、第三时间段的速率不为0，第二时间段的速率为0。
在第一时间段中的第一部分的平均速率大于第一值，表示视频流的传输质量满足要求，不需要提升网络质量，电子设备在第三时间段通过第一网卡传输视频流。
当然，参见图15，视频流的速率分布还可以包括：连续的第四时间段、第五时间 段和第六时间段，第四时间段和第六时间段的速率不为0，第五时间段的速率为0。
在第四时间段中的第二部分的平均速率小于或等于第一值，表示视频流的传输质量不满足要求，需要提升网络质量，电子设备在第六时间段通过电子设备的第二网卡传输视频流。
为了评判标准统一，可以设置第二部分的时长和第一部分的时长相等。
为了使得速率为0的情况下，评判标准更精确，还可以设置第一时间段中的第一部分的结束时间和第一时间段的结束时间相同，第四时间段中的第二部分的结束之间和第四时间段的结束时间相同。
根据图14所示的速率特点和图15所示的速率特点可以理解：速率为0的情况比较特殊，在评估短视频类应用的视频流的传输质量时需要将速率为0的情况单独考虑。
速率不为0的一段时间段内，该段时间内可以选取一部分时间(例如，和第一部分的时长相同)，可以记为第七时间段，确定第七时间段的平均速率小于或等于第一值，电子设备在第八时间段通过第二网卡传输视频流，其中，第八时间段的开始时间为第七时间段的结束时间。当然，确定第七时间段的平均速率大于第一值，电子设备在第八时间段通过第一网卡传输视频流。
在具体实现时，可以将速率为0的情况和速率不为0的情况分开考虑。其中，本申请实施例中的速率均表示周期性(例如，300ms、400ms、500ms、600ms、700ms等)的获得该周期内的视频流的平均下行速率。此时的周期和图14和图15中的速率不为0和为0的周期性分布中的周期不同，周期(例如500ms，)性的获得该周期内以采集周期(例如，10ms、50ms、100ms等)采集的下行速率值的平均下行速率时，获得平均下行速率的周期用于获得采集的下行速率的均值，可以记为均值周期。后续实施例中周期均表示均值周期。后续实施例中与周期性相关的速率值均表示该周期内的平均下行速率值。
平均速率不存在0的情况：多个(例如，2个，3个，4个，5个等)均值周期内的平均速率均较小，则该数据流的传输质量较差。当然，也可以是1个均值周期内的平均速率值较小，则该数据流的传输质量较差。
平均速率存在0的情况：由于网络原因导致平均速率出现0的情况，通常平均速率出现0之前，平均速率已经开始变小(在具体实现时，可以取一段时间内的平均速率，该段时间的结束时间可以为速率变为0的时间)，这种情况才需要提升传输质量；由于当前播放的短视频缓存结束导致平均速率出现0的情况，通常平均速率出现0之前平均速率仍然较大，这种情况不需要提升传输质量。所以，平均速率出现0时，需要追溯到平均速率首次变为0的均值周期之前一个均值周期(最后一个非0速率的均值周期)的平均速率；在具体实现时，可以将平均速率出现0的周期的平均速率延用平均速率首次变为0时上一个均值周期(最后一个非0速率的均值周期)的平均速率。当然，也可以理解每出现平均速率为0的情况，均延用上一均值周期的平均速率。然后在多个均值周期内的平均速率均较小时，则该数据流的传输质量较差。
鉴于上述描述，可以设置以多个均值周期的平均速率作为参考。首先根据单个均值周期(可以记为第一周期)的平均速率确定当前均值周期的周期传输质量，然后根据多个均值周期的周期传输质量确定当前数据流的数据流传输质量。
在确定单个均值周期的周期传输质量时，若平均速率不为0，则可以在平均速率小于或等于阈值A(可以等于第一值，也可以不等于第一值)的情况下，判定当前均值周期的周期传输质量为第二标识(例如，bad)；在平均速率大于阈值A的情况下，判定当前均值周期的周期传输质量为第一标识(例如，good)。若平均速率为0，在延用上一均值周期的平均速率的情况下，相当于延用了上一均值周期的周期传输质量(good或bad)。因此在上一均值周期为bad的情况下，认为当前均值周期的周期传输质量也为bad，在上一均值周期为good的情况下，认为当前均值周期的周期传输质量也为good。本申请实施例对平均速率为0的情况采用延用上一均值周期的周期传输质量还是延用上一均值周期的速率不做限定。当然，实际应用中，平均速率为0时，也可以根据过去多个均值周期(例如，3,5,7个等)的周期传输质量确定，例如，根据多个均值周期传输质量的标识中的众数确定。
综上所述，单个均值周期的周期传输质量的结果包括以下：
Good：本均值周期的平均速度大于或等于阈值A(例如，50kb/s)；平均速率等于0、且上一个均值周期的周期传输质量为good。
Bad：平均速度小于阈值A、且不等于0；平均速率等于0、且上一个均值周期的周期传输质量为bad。
在确定各个均值周期的周期传输质量之后，在当前均值周期可以查看本均值周期以及本均值周期之前连续的M-1个均值周期的周期传输质量，在连续的M个均值周期的周期传输质量中，若存在至少N个均值周期的周期传输质量为bad(可以记为满足第一条件)，则判定数据流的数据流传输质量为bad，需要提升数据流的传输质量。其中，N小于或等于M。若少于N个均值周期的周期传输质量为bad(可以记为满足第二条件)，则判定数据流的数据流传输质量为good，不需要提升数据流的传输质量。
通过上述示例可以理解，视频流的速率满足图14所示示例的速率分布的情况下满足第二条件。即第二条件包括：图14中的视频流在所述第一时间段中的第一部分的平均速率大于第一值。第一条件包括：图15中的视频流在所述第四时间段中的第二部分的平均速率小于或等于所述第一值，还包括上述第七时间段和第八时间段的示例中第七时间段的平均速率小于或等于所述第一值。
按照上述方法可以得到图16所示的一种视频流的平均速率出现0时的网络加速方法的流程示意图，如图所示，该方法包括：
S1，电子设备检测到视频流在第i个均值周期的平均速率为0。
S2，电子设备查看视频流在第i-1个均值周期的周期传输质量。
S3，电子设备将第i-1个均值周期的周期传输质量赋值为第i个均值周期的周期传输质量。
S4，电子设备确定视频流在第i-M+1个均值周期至第i个均值周期的周期传输质量的标识中存在N个bad的情况下，将视频流切换到备用网络上传输，否则，继续检测第i+1个均值周期的平均速率。
本申请实施例以good和bad作为示例，实际应用中，可以采用不同的标识分别表示good和bad，或者采用不同的标识分别表示bad和非bad。
作为一个示例，在一个均值周期内：在判定数据流的数据流传输质量时，若连续 的4个均值周期内，至少3个均值周期的周期传输质量为bad，则判定当前数据流的数据流传输质量bad。在数据流的数据流传输质量为bad的情况下，在存在备用网络的情况下将当前数据流切换到备用网络上或者在不存在备用网络的情况下请求并唤醒备用网络。
基于上述描述，短视频应用(例如抖音)可以按照表4设置流特征、网络质量评估算法和传输质量提升策略。

当然，本申请实施例中以抖音(应用包名com.ss.android.ugc.aweme)的短视频业务场景作为示例，在实际应用中，任一可联网、且存在短视频的业务场景的应用均可以基于表4示例的网络质量评估算法设置的提升传输质量的条件判断是否执行相应的传输质量提升策略。当然，不同应用在短视频场景下的数据流的特征条件可能存在差异，网络质量提升策略也可能存在差异。本申请实施例重点描述网络质量评估算法设置的提升传输质量的条件，对数据流的特征条件和网络质量提升策略不做限定。
为了对上述示例具有更清晰的理解，参照表5。

上述表5所述的场景中，平均速率未出现0，以平均速率出现0的场景为例，参见表6。
表6为本申请实施例提供的另一应用场景(阈值A为50kb/s)
均值周期 1 2 3 4 5 6 7
平均速率(kb/s) 40 60 30 10 0 0 0
周期传输质量 Bad Good Bad Bad Bad Bad Bad
数据流传输质量       Bad Bad Bad Bad
第1个均值周期，平均速率为40(小于阈值A)，且不等于0，则本均值周期的周期传输质量为bad。
第2个均值周期，平均速率为60(大于阈值A)，则本均值周期的周期传输质量为good。
第3个均值周期，平均速率为30(小于阈值A)，且不等于0，则本均值周期的周期传输质量为bad。
第4个均值周期，平均速率为10(小于阈值A)，且不等于0，则本均值周期的周期传输质量为bad，此时最新连续的4个均值周期内，3个均值周期的周期传输质量为bad，该数据流传输质量为bad。
第5个均值周期，平均速率为0，并且上一均值周期得到的周期传输质量为bad，则本均值周期的周期传输质量为bad；此时最新连续的4个均值周期内，3个均值周期的周期传输质量为bad，该数据流传输质量为bad。
第6个均值周期，平均速率为0，并且上一均值周期得到的周期的传输质量为bad，则本均值周期的周期传输质量为bad，此时最新连续的4个均值周期内，4个均值周期的周期传输质量为bad，该数据流传输质量为bad。

该示例中，数据流的平均速率出现0的情况下，通过平均速率出现0之前的几个均值周期的平均速率可以理解：表6所示的场景中数据流的传输质量较差，并不是由于视频的缓存结束导致的平均速率变为0，而是由于网络通道的质量本身可能变差。
下面将以视频缓存结束后平均速率变为0的场景作为示例进行说明，参见表7。
表7为本申请实施例提供的另一应用场景(阈值A为50kb/s)
均值周期 1 2 3 4 5 6 7

第1个均值周期，平均速率为200(大于阈值A)，则本均值周期的周期传输质量为good。
第2个均值周期，平均速率为200(大于阈值A)，则本均值周期的周期传输质量为good。
第3个均值周期，平均速率为100(大于阈值A)，则本均值周期的周期传输质量为good。

第5个均值周期，平均速率为0，且上一均值周期得到的周期传输质量为good，则本均值周期的周期传输质量为good；此时，最新连续的4个均值周期内无周期传输质量为bad，则数据流的传输质量为good。

第7个均值周期，平均速率为0，且上一均值周期得到的周期传输质量为good，则本均值周期的周期传输质量为good；此时，最新连续的4个均值周期内无周期传输质量为bad，则数据流的传输质量为good。
上述示例中，还可能出现一种情况，可能在短视频缓存即将结束速率快速下降时，平均速率是从阈值A的左右(例如略小于阈值A)降到0。即在平均速率为0时，仅通过之前一个均值周期的周期传输质量可能存在误判的情况，本申请实施例还可以在平均速率为0时通过之前至少两个均值周期的周期传输质量确定当前均值周期的周期传输质量。
Bad：平均速度小于阈值A、且不等于0；平均速率等于0、且之前两个均值周期的周期传输质量均为bad。
表8以平均速率等于0、且之前一个均值周期的周期传输质量为bad时确定当前均值周期的周期传输质量为bad为例说明，若在平均速率将为0之前的均值周期的平均速率小于50kb/s，例如，49kb/s。按照之前的判断方式可能存在误判的现象。
表8为本申请实施例提供的另一应用场景(阈值A为50kb/s)
均值周期 1 2 3 4 5 6 7
平均速率(kb/s) 200 200 100 49 0 0 0
周期传输质量 Good Good Good Bad Bad Bad Bad
数据流传输质量       Good Good Bad Bad
表9以速率等于0、且之前两个均值周期的周期传输质量均为bad时确定当前均值周期的周期传输质量为bad为例说明：若在平均速率将为0之前的均值周期的平均速率小于50kb/s，例如，49kb/s。按照当前的判断方式避免之前的误判现象。
表9为本申请实施例提供的另一应用场景(阈值A为50kb/s)
均值周期 1 2 3 4 5 6 7
平均速率(kb/s) 200 200 100 49 0 0 0
周期传输质量 Good Good Good Bad Good Good Good
数据流传输质量       Good Good Good Good
通过表8和表9的对比可以理解，若阈值A设置的足够合理，在判断某个均值周期的周期传输质量时，可以将平均速率等于0、且上一个均值周期的周期传输质量为bad的均值周期的周期传输质量设置为bad。为避免阈值A设置不合理或者很难找到一个合理的值作为阈值A，则可以将平均速率等于0、且之前两个(或更多)均值周期的周期传输质量为bad的均值周期的周期传输质量设置为bad。
另外，由于一个均值周期的时长为人为设置的时间值，在具体实现时，若均值周期时长设置的比较小，则需要将平均速率等于0、且之前更多均值周期的周期传输质量为bad的均值周期的周期传输质量设置为bad。
换言之，实际应用中，也可以设置时间值，在速率(可以为采集时刻的速率值，也可以时某个周期的平均速率值)由非0变为0时，若速率变为0(t1时刻速率由非0变为0)之前预设时间段(t2时刻至t1时刻对应的时间段，其中，t2＝t1+ty，ty为预设时间)的平均速率值小于阈值B，则表示速率变为0之前的速率较低，网络质量较差，当前速率变为0为网络质量较差的情况，则需要执行传输质量提升策略。在速率由非0变为0时，若速率变为0(t1时刻速率由非0变为0)之前预设时间段(t2时刻至t1时刻对应的时间段，其中，t2＝t1+ty，ty为预设时间)的平均速率值大于或等于阈值B，则表示速率变为0之前的速率较高，网络质量较优，当前速率变为0为短视频缓存结束，则不需要执行传输质量提升策略。
如前所述，在判断数据流的传输质量较差(bad)的情况下，在存在备用网络的情况下将当前数据流切换到备用网络上或者在不存在备用网络的情况下请求并唤醒备用网络。当然，实际应用中，还可以设置其他拉起备用网络的条件，例如，在连续的M个均值周期中存在N-1个均值周期的周期传输质量为bad的情况拉起备用网络，在连续的M个均值周期中存在N个均值周期的周期传输质量为bad的情况将当前数据流切换到备用网络。
