具体地，通过对第二网络通道的探测，第一设备10可以获取第二网络通道的网络信息，其中，该网络信息可以包括第二网络通道的路径。可以理解的是，该第二网络通道是可用的网络通道，由此可以使得第一设备10在监测到第一网络通道不满足业务要求时，可以立即切换到第二网络通道，减少切换的时延。
当存储上述第二网络通道的路径后，可以进一步探测第一应用的报文流。
步骤303，在第一应用的多个报文流中确定特征报文流，对特征报文流中的报文进行统计，得到第一统计结果，基于第一统计结果将特征报文流切换至第二网络通道。

步骤403，第一策略管理组件124接收环境探测组件121发送的第一通知消息，判断当前网络应用是否满足开启加速的条件。
具体地，当第一策略管理组件124接收环境探测组件121发送的第一通知消息后，可以从第一通知消息中确定该网络应用已切换到前台。接着，第一策略管理组件124可以进一步确定该网络应用是否包含在预设应用白名单内。
在具体实现时，第一策略管理组件124中可以预设应用白名单，该应用白名单可以包括多个网络应用，每个网络应用可以通过上述身份标识进行标识，该应用白名单可以用于表征可以开启加速的网络应用。其中，上述预设应用白名单中的网络应用可以包括业务类型，例如，上述预设应用白名单中的网络应用的业务类型都可以是敏感类，该敏感类业务可以包括时延敏感类业务、丢包率敏感类业务等。当通过对第一通知消息中的网络应用的身份标识与预设应用白名单中的网络应用的身份标识的比对，可以确定第一通知消息中的网络应用是否包含在预设应用白名单中。若第一通知消息中的网络应用包含在预设应用白名单中，则可以确定该网络应用满足开启加速的条件，若第一通知消息中的网络应用不包含在预设应用白名单中，则可以确定该网络应用不满足开启加速的条件。
示例性的，表1为网络应用的白名单。

可以理解的是，若当前的网络应用不在上述预设应用白名单中，也就是说，当前的网络应用的业务类型为非敏感类务，则电子设备100在探测到主网络通道变差时，可以进一步探测其他质量较好的网络通道，由此可以直接将上述非敏感类业务切换到质量较好的网络通道上。
步骤404，第一策略管理组件124向第二路径管理组件131发送通道启用消息，用于启用一条网络通道。
具体地，若第一策略管理组件124确定当前网络应用满足开启加速的条件，则可以向第二路径管理组件131发送通道启用消息，其中，该通道启用消息用于指示第二路径管理组件131可以启用一条网络通道(例如，主网络通道)。

当第一路径管理组件123接收到第二路径管理组件131发送的主网络通道请求后，可以在上述多条网络通道中选取一条网络通道作为主网络通道(例如，该主网络通道为主WIFI通道)，并将该主网络通道的路径发送给第二路径管理组件131。

可以理解的是，当前的网络应用(例如，图6中的视频应用)可以包括多个流(例 如，视频流及音频流)，该多个流可以承载在上述主网络通道上。
步骤408，第一策略管理组件124向流量感知组件133发送流量探测请求。
具体地，该流量探测请求可以用于指示流量感知组件133启动主网络通道上的网络应用的报文统计。其中，该流量探测请求可以包括当前待探测的网络应用的身份标识(例如UID)，用于请求对该主网络通道上的与上述身份标识UID对应的网络应用的流进行探测。可以理解的是，上述网络应用的流可以是报文的形式。
需要说明的是，本步骤408可以与步骤404同时执行，也可以在步骤404之后的任一时刻执行，本申请对此不做特殊限定。
步骤409，流量感知组件133向流量上报组件141发送流量上报请求。
具体地，当流量感知组件133收到第一策略管理组件124发送的流量探测请求后，可以向流量上报组件141发送流量上报请求，其中，该流量上报请求可以用于指示流量上报组件141对当前主网络通道上的网络应用的报文进行探测，并将探测到的报文进行上报。可以理解的是，上述流量探测请求可以包含网络应用的身份标识(例如UID)。
步骤410，流量上报组件141进行流量探测，并将探测到的报文上报给流量感知组件133。
具体地，当流量上报组件141接收到上述流量感知组件133发送的流量上报请求后，可以根据上述流量上报请求中的网络应用的身份标识(例如UID)，对与网络应用的身份标识对应的网络应用的报文进行探测，由此可以得到主网络通道上网络应用的报文，并可以将上述探测到的网络应用的报文上报给流量感知组件133。
在具体实现时，上述流量上报组件141可以调用组件(例如，安卓系统的Netfilter组件)获取上述主网络通道上的网络应用的报文。可以理解的是，上述Netfilter组件仅为示例性说明，并不构成对本申请实施例的限定，在一些实施例中，也可以通过其他组件完成上述报文的探测。
示例性的，上述网络通道的参数可以通过如下代码实现：
typedef struct{
bool available；
bool slowDevForbbiden；
uint64_t qoeBadTimeStamp；
uint64_t chQoeBadStartTime；
uint32_t rcvRate；
}
可以理解的是，上述探测的报文可以是当前网络应用中一个或多个特征流的报文，其中，该特征流可以是网络应用中敏感性最高的流，也就是对当前网络应用影响较大的流。此外，通过上述网络通道的参数可以对网络通道的质量进行评估。
步骤411，环境探测组件121探测到电子设备100所处的场景。
具体地，上述场景可以是用户所处的场景，也就是电子设备100所处的场景。示例性的，上述场景可以是用户正处于电梯中。可以理解的是，上述电梯场景仅为示例性说明，还可以包括其他会引起网络变化的场景，例如，在高铁上，在车库等场景。现以电梯场景为例进行说明，当用户进入电梯后，电梯上升或下降，会导致用户的重 力发生变化，例如，电梯上升会引起超重，电梯下降会引起失重。因此，可以通过电子设备100中的加速度传感器进行探测，当加速度传感器探测到用户处于失重或超重时，也就是说，探测到电子设备100在垂直方向的加速度，由此可以确定用户正处于电梯环境中。此时，若环境探测组件121探测到用户正处于电梯中，则可以向第一策略管理组件124发送场景变化通知消息，其中，该场景变化通知消息用于通知第一策略管理组件124用户所处的场景发生了变化(例如，用户进入了电梯)，由此可以使得第一策略管理组件124启动备用网络通道的探测。
此外，由于电梯在上升或下降过程中，会根据不同的用户的需求(例如，不同的用户可以点按不同的楼层)进行停靠，因此，电梯会出现在垂直方向上持续运行或走走停停的现象。由于在上述电梯升降过程中，电子设备100没有探测到水平方向的运动，因此，仍可以确定该电子设备100处于电梯中，其中，上述水平方向的运动可以通过电子设备100中的加速度传感器进行探测获得。例如，通过上述加速度传感器探测到有水平方向的加速度，则可以确定有水平方向的运动。
当电子设备100探测到电子设备100有水平方向的加速度，也就是说，电子设备100发生水平运动时，可以确定用户出了电梯，换句话说，就是该电子设备100已经出了电梯。此时，可以无需提前进行备用网络通道的检测，也就无需向第一策略管理组件124发送场景变化通知消息，由此可以节省电子设备100因备用网络通道的探测带来的电量消耗。
可选地，电子设备100也可以通过检测移动网络的信号强度的强弱，确定用户所处场景是否发生变化。例如，当移动网络的信号强度变弱，则可以确定用户进入了一个较差的网络环境，此时，电子设备100可以确定场景发生了变化，并可以向第一策略管理组件124发送场景变化通知消息，用于提前进行备用网路通道的探测。当移动网络的信号强度变强，则可以确定用户进入了一个较好的网络环境，此时，可以无需提前进行备用网络通道的检测，也就无需向第一策略管理组件124发送场景变化通知消息，由此可以节省电子设备100因备用网络通道的探测带来的电量消耗。
步骤412，环境探测组件121将场景变化通知消息发送给第一策略管理组件124。
具体地，当环境探测组件121探测到场景变化后，可以将场景变化通知消息发送给第一策略管理组件124。
步骤413，第一策略管理组件124将指示场景变化的场景变化通知消息转发给第二路径管理组件131。
步骤414，第二路径管理组件131向第一路径管理组件123请求备用网络通道。
具体地，由于在电梯中通常信号都较差，而在进电梯后再进行通道的选择并切换会造成业务较大的时延，导致用户的体验变差。因此，在探测到用户进入到电梯时，可以预先选取一条备用网络通道，由此可以加快通道切换的速度，减少通道切换给业务带来的时延。
当第二路径管理组件131接收到上述第一策略管理组件124发送的场景变化通知消息后，可以向第一路径管理组件123发送备用网络通道请求，其中，该备用网络通道请求可以用于请求一条备用网络通道。
可选地，上述备用网络通道请求还可以携带标签，该标签可以用于指示对主网络 通道的切换的预测，并不真正进行切换。
现结合图7a-7c，以手机为例对上述备用网络通道的选取进行说明。如图7a所示，手机具有主WIFI通道(例如WIFI1)、辅WIFI通道(例如WIFI2)、主蜂窝通道(例如Mobile1)及辅蜂窝通道(例如Mobile2)等4条网络通道的能力。假设手机当前在WIFI1通道(主网络通道)运行一个网络应用(例如微信)，该网络应用包括流A(例如视频流)和流B(例如音频流)。当手机接收到场景变化通知后，可以提前选取备用网络通道，其中，该备用网络通道可以是上述辅WIFI通道(例如WIFI2)、主蜂窝通道(例如Mobile1)及辅蜂窝通道(例如Mobile2)中的通道质量最好的一条。当选取上述辅WIFI通道(例如WIFI2)、主蜂窝通道(例如Mobile1)及辅蜂窝通道(例如Mobile2)中的一条网络通道作为备用网络通道(例如，Mobile1通道)后，可以将该Mobile1通道的路径进行存储。
当手机通过进一步报文探测，发现流A的质量已经不满足需求，此时，可以仅将上述流A切换到备用网络通道，也就是Mobile1通道上。如图7b所示，此时，上述流B可以继续承载在主网络通道，也就是WIFI通道上，而流A可以承载在备用网络通道，也就是Mobile1通道上。
需要说明的是，上述示例仅示例性的示出了一条流进行切换的场景，并不构成对本申请实施例的限定，在一些实施例中，也可以包含多条流进行切换的场景。
可选地，当手机通过进一步报文探测，发现流A的质量已经不满足需求，此时，可以将上述流A及流B都切换到备用网络通道，也就是Mobile1通道上。如图7c所示，此时，上述流A及流B都承载在Mobile1通道上，WIFI1通道关闭。
接着，结合图8a和图8b，以手机为例对通道切换的触发条件进行说明。图8a为非敏感类业务的通道切换触发过程。如图8a所示，手机中的流量感知组件133在预设第一时长内接收流量上报组件141探测到的心跳流报文，通过对上述预设第一时长内的心跳流报文的统计分析，可以确定网络通道质量的是否变差。其中，由于当前业务是非敏感类业务，因此，上述预设第一时长可以设置的较长，例如5s。当流量感知组件133确定当前的网络通道质量变差后，可以发送切换通知给第二策略管理组件132，以触发网络通道的切换，例如，可以通过对其他网络通道的质量进行评估，并将当前的非敏感类业务切换到质量最优的其他网络通道上。
图8b为敏感类业务的通道切换触发过程。如图8b所示，手机中的第二路径管理组件131接收到第一策略管理组件124发送的场景变化通知消息后，可以确认场景发生变化。此时，该第二路径管理组件131可以请求备用网络通道，以便在网络应用的特征流质量变差时，可以及时切换到上述备用网络通道，以节省切换的时间，提升用户的感受。接着，手机中的流量感知组件133在预设第二时长内接收流量上报组件141探测到的心跳流报文，通过对上述预设第二时长内的心跳流报文的统计分析，可以确定当前网络应用中特征流的业务质量。其中，上述预设第二时长可以和预设第一时长等长，例如5s，也可以比预设第一时长设置的短，例如3s。当确定特征流的业务质量变差时，可以发送切换通知给第二策略管理组件132，以触发网络通道的切换，例如，可以将当前网络应用的特征流切换到上述备用网络通道上。
步骤415，第一路径管理组件123接收备用网络通道请求，请求各可选网络通道 的启用状态。
具体地，当第一路径管理组件123接收到上述第二路径管理组件131发送的备用网络通道请求后，可以向网络探测组件122发送通道状态请求，其中，该通道状态请求可以用于请求获得各可选网络通道的启用状态。可以理解的是，上述启用状态可以包括可用及不可用。上述可用状态可以用于表征该可选网络通道可以启用，上述不可用状态可以用于表征该可选网络通道禁止启用。该可选网络通道可以包括辅WIFI通道、主蜂窝通道及辅蜂窝通道等。
步骤416，网络探测组件122探测各可选网络通道的启用状态，并向第一路径管理组件123发送各可选网络通道的启用状态。
具体地，当网络探测组件122接收到第一路径管理组件123发送的通道状态请求后，可以检测各可选网络通道的启用状态。在具体实现时，该网络探测组件122可以用于管理各可选网络通道的开关，当任一可选网络通道开启后，该可选网络通道处于可用状态，当任一可选网络通道关闭后，该可选网络通道处于不可用状态。因此，当网络探测组件122检测到第一路径管理组件123请求的所有可选网络通道的启用状态后，可以将上述所有可选网络通道的启用状态发送给第一路径管理组件123。
步骤417，第一路径管理组件123请求各可用网络通道的通道质量。
具体地，当第一路径管理组件123接收到各可选网络通道的启用状态后，可以选取可用网络通道(也就是处于可用状态的可选网络通道)，并可以进一步向通道及应用质量评估组件125发送通道评估请求，其中，该通道评估请求可以用于请求评估可用网络通道的质量。
步骤418，通道及应用质量评估组件125对各可用网络通道的质量进行评估，并将评估结果发送给第一路径管理组件123。
具体地，当通道及应用质量评估组件125接收到第一路径管理组件123发送的通道评估请求后，可以根据该通道评估请求对各可用网络通道的质量进行评估。示例性的，该通道质量可以包括该通道的时延、丢包率、带宽及速率等。上述评估可以是对可用网络通道的往返时延(Round-Trip Time，RTT)进行评估，往返时延最小的网络通道为最佳。可选地，当可用网络通道有历史选用记录时，也就是说，上述可用网络通道曾经被选用为网络通道过，此时，可以结合上述RTT及历史记录对通道质量进行评估，其中，该历史记录可以包括历史接收速率、通道质量为差的历史次数等，本申请实施例对上述通道质量的评估方式不做特殊限定。当通道及应用质量评估组件125对通道评估请求中所有可用网络通道的质量评估完成之后，可以将上述评估结果发送给第一路径管理组件123。
步骤419，第一路径管理组件123基于评估结果确定备用网络通道，并将备用网络通道的路径发送给第二路径管理组件131。
具体地，当第一路径管理组件123接收到上述评估结果后，可以基于上述评估结果选取最佳的可用网络通道作为备用网络通道，并可以将上述备用网络通道的路径发送给第一路径管理组件123。
步骤420，第二路径管理组件131接收并存储第一路径管理组件123发送的备用网络通道的路径。
具体地，当第二路径管理组件131接收到第一路径管理组件123发送的备用网络通道的路径后，可以预先存储该备用网络通道的路径。可以理解的是，由于在步骤411中仅是检测到场景变化，也就是说，当前的网络可能会对业务造成卡顿，但是还没有达到切换的条件，此时，电子设备100并不切换到该备用网络通道，也就是说，电子设备100仍在使用主网络通道。
示例性的，当第二路径管理组件131在t1时刻接收到第一路径管理组件123发送的备用网络通道的路径后，可以预先存储该备用网络通道的路径。此时，电子设备100并不切换到该备用网络通道，也就是说，电子设备100仍在使用主网络通道。接着，当在t2时刻检测到当前的网路应用的特征流的质量变差，已经达到切换的条件，此时，电子设备100可以将上述特征流由主网络通道切换到备用网络通道。
步骤421，流量上报组件141上报流量至流量感知组件133。
具体地，流量上报组件141可以持续探测当前主网络通道的报文，并将探测到的报文上报给流量感知组件133。
步骤422，流量感知组件133接收流量上报组件141上报的报文，对报文进行分析，得到报文分析结果，并将报文分析结果发送给第二策略管理组件132。
具体地，上述报文可以是主网络通道上的网络应用的各个流的报文。当流量感知组件133接收到上述报文后，可以对上述报文进行分析。其中，上述报文分析可以是基于报文的特征，以此来识别特征流，其中，该特征流可以是网络应用中敏感性最高的流。举例来说，以和平精英游戏为例，该游戏的特征流可以是语音流，也就是说，语音流对该游戏的影响是比较大的，敏感性最高，当语音流质量不好(例如，时延和丢包率都不满足要求)时，会严重影响用户的游戏体验。因此，需要识别语音流，并进一步统计及分析报文中的语音流报文。由此可以得到报文分析结果，该报文分析结果可以用于表征该特征流是否满足业务需求，例如，是否满足时延需求或是否满足丢包率需求等。并可以将上述报文分析结果发送给第二策略管理组件132。
其中，上述语音流的报文的识别可以通过心跳包统计实现。示例性的，以UDP协议为例，该语音流的数据报文特征可以通过如下特征表征：
上行：udp.payload[6]＝0x64；
下行：udp.payload[6]＝0x65。
图9为上述UDP协议的语音流的心跳报文示意图。
也就是说，对上述上下行报文中的载荷中的预设字段的读取，可以识别该报文是否是语音流数据包。
接着，可以对语音流的报文进行统计，由此可以获得上述语音流的报文的时延和/或丢包率。在具体实现时，可以统计预设时长(例如，5s)内的语音流的报文。示例性的，若上述语音流的报文的时延和/或丢包率达不到要求时，则可以确定该语音流的质量为差，此时，可以触发切换，用于将上述语音流切换到备用网络通道上。需要说明的是，上述示例仅以游戏为例进行示例性说明，在具体应用中，还可以包括其他网络应用，例如，百度网盘，该网络应用的特征流是下载流，也就是说，可以在上述报文中找到下载流的报文，而该下载流的报文的影响因素可以是速率。此外，上述网络应用还可以包括微信等社交网络应用，该网络应用的特征流是视频流，也就是说，可 以在上述报文中找到视频流的报文，而该视频流的报文的影响因素可以是时延/或丢包率。
可以理解的是，上述特征流除上述语音流之外，还可以包括游戏中的对战流。以和平精英为例，通过周期统计UDP报文个数可以判断当前的报文流是否是对战流。目前，和平精英采用的周期是500ms，因此，可以统计周期内的报文总数判断是否是对战流，例如，上述500ms周期的报文总数大于10个，则该报文流为对战流。图10为UDP协议的对战流的报文统计示意图。如图10所示，横轴为时间，纵轴为报文总数，由于每秒基本保持在30个报文，因此，可以通过计算确定每500ms有15个报文，由此可以确定该报文流是对战流。
接着，以王者荣耀为例，其中，王者荣耀采用过滤UDP协议号和报文头特征payload＝0x00010000来过滤对战报文。图11为UDP协议的对战流的心跳报文示意图。
步骤423，第二策略管理组件132基于报文分析结果确定切换，并请求获取备用网络通道的路径。
具体地，当第二策略管理组件132接收到流量感知组件133上报的报文分析结果后，可以根据报文分析结果判断是否进行通道切换。在具体实现时，若当前的网络应用的特征流(例如，游戏中的语音流、微信中的视频流或百度网盘的下载流)不满足要求(例如，时延和/或丢包率)，则可以确定需要进行通道切换。此时，第二策略管理组件132可以向第二路径管理组件131发送备用网络通道路径获取请求，用于获取备用网络通道的路径，举例来说，若备用网络通道为主蜂窝，则备用网络通道的路径例如可以是Mobile1。
示例性的，上述请求备用网络通道的路径可以通过如下代码实现：
Figure PCTCN2022072713-appb-000002
Figure PCTCN2022072713-appb-000003
此外，在具体实现时，上述网络通道的路径(例如，该路径可以用网卡或sim卡的设备号表征)可以在数据结构中进行定义，代码示例如下：
Figure PCTCN2022072713-appb-000004
Figure PCTCN2022072713-appb-000005
如上述代码所示，其中，sk_bound_dev_if为切换的目标网卡或目标sim卡的设备号。可以理解的是，通过上述网卡或sim卡可以接收报文，该接收报文的代码可以参考如下示例：
pktinfo.msg.flow_msg.dev_if＝sk->sk_bound_dev_if；
其中，pktinfo为接收到的报文，msg.flow_msg为报文流的名称。
可以理解的是，若通过报文分析，确定当前的网络应用的特征流满足需求，也就是说，无需进行切换，此时，第一设备10可以删除上述备用网络通道的路径，由此可以释放资源，同时也可以节省第一设备10的功耗。可选地，第一设备10也可以在预设时长(例如，预设第三时长)后删除上述备用网络通道的路径，由此可以保证在该预设第三时长内，如果特征流的质量变差，可以及时的切换至备用网络通道，避免因删除上述备用网络通道的路径导致无法切换。
需要说明的是，由于电子设备100所处的环境的不同，无线网络的差异较大，例如，当电子设备100检测到当前所处网络环境较差时，可以拉起备用网络。接着，当电子设备100检测到当前业务满足业务需求时，无需进行切换时(例如，电子设备100进入到一个较好的网络环境)，电子设备100可以继续使用当前网络，不切换到上述备用网络，因此，电子设备100可以仅执行备用网络的检测，例如执行步骤415-步骤420，以完成备用网络的检测。进一步地，电子设备100在完成上述备用网络的检测之后，还可以激活上述备用网络，上述激活操作可以加快切换的流程，由此可以节省切换的时延。也就是说，当电子设备100检测到当前所处的环境(例如，电梯场景)时，可以只进行备用网络的检测，也可以进行备用网络的检测及备用网络的激活，而上述备用网络的检测阶段及备用网络的激活还没有真正执行切换。当电子设备100检测到当前业务无法满足业务需求时，可以将当前业务(例如，当前业务的一个或多个流)切换到已激活的备用网络上。
步骤424，第二策略管理组件132向第二路径管理组件131发送备用网络通道的路径。
步骤425，第二策略管理组件132向策略执行组件142发送通道切换指示。
具体地，当第二策略管理组件132接收到第二路径管理组件131发送的备用网络通道的路径后，可以向策略执行组件142发送通道切换指示，其中，该通道切换指示可以用于指示策略执行组件142将上述特征流由当前的主网络通道切换至备用网络通道，由此可以更快的完成通道切换，减少通道切换带来的时延，提高用户的体验。
步骤426，策略执行组件142执行通道切换。
具体地，当策略执行组件142接收到第二策略管理组件132发送的通道切换指示后，可以将上述特征流由当前的主网络通道切换至备用网络通道，也就是说，上述网络应用的其他流可以继续承载在主网络通道上运行，上述特征流可以承载在备用网络通道上运行，由此可以快速的完成切换，进而可以保证业务的质量以及用户的体验。
可选地，可以将上述网络应用整个切换至备用网络通道，也就是说，可以停用上述主网络通道，上述网络应用的所有流都承载在备用网络通道上运行。
图12为手机使用备用网络通道的示意图。如图12所示，当手机接收到通道切换 指示后，可以将视频流由当前的主网络通道切换至备用网络通道，并可以使用备用网络通道进行视频的观看，以避免视频的卡顿。
