详述
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开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公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1为本公开提供的数据传输方法的流程图，该方法可以应用于支持多种通信模式(例如支持WiFi6、5G、以太网等)，配置有多个网络接口的终端，包括但不限于路由器、智能手机、笔记本电脑、交换机等，该方法可以包括如下步骤：
S11.接收到数据包后，对数据包进行拆分得到多个子数据包；
S12.针对任一目标子数据包，根据预设的数据传输策略确定目标子数据包对应的目标网络接口；
S13.通过所述目标网络接口对应的目标路由转发路径对所述目标子数据包进行传输；
S14.确定所述目标路由转发路径的网络质量信息；
S15.若所述网络质量信息不符合预设要求，则确定当前时刻可用的网络接口对应的网络质量信息；
S16.从当前时刻可用的网络接口中选取任意网络质量信息符合预设要求的网络接口作为替换网络接口；以及
S17.利用所述替换网络接口对应的路由转发路径对所述目标子数据包进行传输。
本实施例应用于终端，数据包包括但不限于外部设备向终端发送的数据包以及终端自身生成的数据包。
在某些实施方案中，预先设置一种数据拆分规则，当接收到数据包后，采用此预设的数据拆分规则对数据包进行拆分，数据拆分规则可以根据实际需求设置，例如数据拆分规则可以为将数据包拆分成字节长度不大于预设长度的子数据包，其中预设长度可以根据实际需求设置，例如100字节。
在某些实施方案中，还可以预先根据实际需求设置多种数据拆分规则，然后针对不同的数据包采用不同的数据拆分规则进行拆分。
如图2所示，在接收到数据包后，可以采用下述步骤对数据包进行拆分：
S21.确定所述数据包对应的数据源标识；
S22.根据预设的数据拆分策略，确定与所述数据源标识对应的目标数据拆分规则；以及
S23.利用所述目标数据拆分规则对所述数据包进行拆分，得到多个子数据包。
在某些实施方案中，数据包中携带有该数据包对应的数据源标识，对数据包进行解析进行得到数据包对应的数据源标识。其中，数据包的数据源标识可以是生成该数据包的应用程序的ID(Identifier，标识符)，也可以是该数据包的源端口号，即生成该数据包的IP(Internet Protocol，网际协议)端口号。
在某些实施方案中，数据拆分策略为用户或开发人员根据实际需求预先设置的，数据拆分策略中可以包含多种数据拆分规则，以及各种数据拆分规则与数据源标识的对应关系，一个数据拆分规则可以与多个数据源标识对应。在某些实施方案中，可以针对各数据拆分规则设置规则标识，并建立数据拆分规则与规则标识之间的映射关系，创建规则标识与数据源标识的对应关系表，将对应关系表和数据拆分规则共同组成数据拆分策略。基于此，本步骤S22在确定出数据包的数据源标识后，可以根据数据源标识从数据拆分策略的对应关系表中查找与该数据源标识对应的规则标识，然后确定与查找出的规则标识存 在映射关系的数据拆分规则为目标数据拆分规则。其中数据拆分规则以及数据拆分规则与数据源表示的对应关系，均可以为用户或开发人员根据需求设置的，本实施例不做具体限定。
在某些实施方案中，若接收到的数据包对应的目标数据拆分规则为将数据包拆分成字节长度不大于100字节的子数据包，数据包的字节长度为1000字节，则按照目标数据拆分规则对数据包进行拆分，会得到10个字节长度为100的子数据包。
在某些实施方案中，将数据包拆分成多个子数据包，以子数据包为粒度进行数据传输，分别针对各子数据确定网络接口，从而可以实现针对不同的子数据包采用不同的网络接口进行数据传输，进而避免了数据包采用一个网络接口在进行网络接口切换时，出现的数据传输中断的问题。
在某些实施方案中，针对S11中得到的多个子数据包中的任一子数据包均执行S12-S16的步骤，为便于描述，本实施例针对一个子数据包进行描述，并称该子数据包为目标子数据包。
在某些实施方案中，如图3所示，可以采用下述步骤确定目标子数据包对应的目标网络接口：
S31.确定当前时刻可用的网络接口为传输接口；
S32.确定传输接口的数量；
S33.根据预设的权重分配策略，确定与所述数量对应的权重分配方案；
S34.根据所述权重分配方案确定各传输接口的传输权重；
S35.根据各传输接口的传输权重，对所述多个子数据包进行分组，每一个分组对应一个传输接口；以及
S36.确定所述目标子数据所属的分组对应的网络接口为目标网络接口。
在执行本实施例之前，终端先在WLAN(Wireless Local Area Networks，无线局域网)网络、5G网络、4G网络、Ethernet和LTE(Long Term Evolution，长期演进)等网络中的任意多个网络中分别进行网络注册，并从每一个注册网络中获取注册信息。
终端还需要实时监控每个网络接口的网络状态。当网络接口开启且网络未断开时，确定该网络接口可用，并确定该网络接口为传输接口。
在某些实施方案中，权重分配策略可以为用户或开发人员根据实际需求预先设置的，权重分配策略中包含权重分配方案和权重分配方案与传输接口数量的对应关系。基于此，在S32确定出传输接口的数量后，本步骤S33即可根据权重分配策略中权重分配方案与传输接口数量的对应关系，确定出与该数量对应的权重分配方案。
在某些实施方案中，权重分配方案中包含至少一个传输权重。权重分配方案中的传输权重与传输接口一一对应，因此权重分配方案中包含的传输权重的数量与传输接口的数量一致，例如，若传输接口的数量为2，则对应的权重分配方案中就包含2个传输权重，若传输接口的数量为3，则对应的权重分配方案中就包含3个传输权重。
在某些实施方案中，权重分配方案中包含的各传输权重分别对应一个顺序标记，该顺序标记用于标识传输权重对应的传输接口在所有传输接口中的优先级顺序，例如下表1所示，为传输接口的数量为2时，对应的权重分配方案：
表1
顺序标记 传输权重
1 0.7
2 0.3
在某些实施方案中，顺序标记1表示对应的传输接口的优先级顺序排在2个传输接口中的第一位，顺序标记2表示对应的传输接口的优先级顺序排在2个传输接口中的第二位。上表则表示，在两个传输接口中，优先级最高的(即优先级顺序排在第一位的)传输接口对应的传输权重为0.7，优先级低的(即优先级顺序排在第二位的)传输接口对应的传输权重为0.3。
在某些实施方案中，表1中所示的传输权重的值只是示例性的，具体的值可以根据需求设定，只要所有的传输权重的加和为1即可， 本实施例对此不作具体限定。
在某些实施方案中，根据所述权重分配方案确定各传输接口的传输权重，可以包含如下步骤：
步骤1：确定各传输接口对应的优先级；
步骤2：按照优先级由高到低的顺序对传输接口进行排序，并为各传输接口设置顺序标记；以及
步骤3：针对任一传输接口，确定权重分配方案与该传输接口的顺序标记对应的传输权重，作为该传输接口的传输权重。
在某些实施方案中，用户或开发人员可以根据实际需求预先针对终端中注册的各网络接口设置优先级。
在某些实施方案中，传输接口的数量为2个，分别为WLAN网络接口和5G网络接口，其中WLAN网络接口的优先级为第一优先级，5G网络接口的优先级为第二优先级，第一优先级高于第二优先级，则对传输接口按照优先级由高到低进行排序后，WLAN网络接口排在第一位，5G网络接口排在第二位，为WLAN网络接口设置顺序标记1，为5G网络接口设置顺序标记2。
在某些实施方案中，可以确定传输接口中，WLAN网络接口对应的传输权重为0.7，5G网络接口对应的传输权重为0.3。
在某些实施方案中，传输接口的传输权重表示传输接口可传输的子数据包数量在所有子数据包中的占比，因此可以按下式分别计算各传输接口传输的子数据包的数量：
M i＝Si×N
其中，M i表示传输接口i传输的子数据包数量，S i表示传输接口i的传输权重，N表示S11中拆分得到的子数据包的总个数。
在某些实施方案中，传输接口包括WLAN网络接口和5G网络接口，WLAN网络接口的传输权重为0.7，5G网络接口的传输权重为0.3，S11共拆分得到10个子数据包，则WLAN网络接口可传输7个子数据包，5G网络接口可传输3个子数据包。
计算得到各传输接口可传输的子数据包数量后，对S11中得到的多个子数据包进行分组，一个分组对应一个传输接口，即有几个传输 接口就可以分成几组，在进行分组时，根据传输接口可传输的子数据数量进行分组，例如S11共拆分得到10个子数据包，WLAN网络接口可传输7个子数据包，5G网络接口可传输3个子数据包，则可以将子数据分成两组，第一组包含7个子数据包，第二组包含3个子数据包，其中第一组与WLAN网络接口对应，第二组与5G网络接口对应。
在某些实施方案中，在进行分组时，可以随机确定将子数据包划分到任一分组，例如从10个子数据包中随机选取7个组成第一分组，剩下的3个组成第二分组。
在某些实施方案中，还可以按照一定的规则将子数据包划分到对应的分组，比如按照子数据包对应的拆分顺序进行分组，例如，共10个子数据包，按照子数据包对应的拆分时间，将拆分时间靠前的前7个子数据包组成第一分组，将拆分时间靠后的3个子数据包组成第二分组。
当然除了上述两种分组方法，还可以采用其他方式进行分组，本实施例对此不作具体限定。
在某些实施方案中，若目标子数据所属的分组为第一分组，则就确定WLAN网络接口为对应的目标网络接口，若目标子数据所属的分组为第二分组，则确定5G网络接口为对应的目标网络接口。
将多个子数据包分散到不同的网络接口上进行传输，保证了在一个网络接口关闭或网络断开是，数据包还可以通过其他网络接口进行传输，避免了出现传输中断的问题。
在某些实施方案中，由于网络接口的优先级在设置时通常是根据实际需求设置的，也就是说用户更倾向于使用优先级高的网络接口进行传输，所以根据网络接口的优先级确定对应的传输权重，进而根据传输权重为网络接口分配子数据包，可以使得数据传输更加符合用户的需求。
终端基于目标网络接口对应的目标路由转发路径建立数据连接，连接建立后通过相应的注册网络对目标子数包进行数据传输，并接收反馈数据。
在某些实施方案中，终端根据从目标网络接口对应的注册网络中 获取的注册信息，生成目标网络接口对应的路由转发路径。例如，在终端根据从WLAN网络中获取的注册信息，生成与WLAN网络接口对应的路由转发路径(即路由信息)，并保存，根据从5G网络中获取的注册信息，生成与5G网络接口对应的路由转发路径(即路由信息)，并保存。
在某些实施方案中，在利用目标传输路径传输目标子数据包的过程中，监控目标路由转发路径对应的网络质量信息。便于即使发现目标路由转发路径存在的问题。
在某些实施方案中，可以通过下述方式确定路由转发路径的网络质量信息：
获取路由转发路径的传输速率和传输带宽，根据所述传输速率和所述传输带宽确定路由转发路径对应的网络质量信息。其中获取路由转发路径的传输速率和传输带宽，指的是获取路由转发路径对应的网络接口所对应的注册网络的传输速率和传输带宽。
在某些实施方案中，可以根据预设的传输速率和传输带宽对应的权重，采用加权求和的方式计算网络质量分数，将网络质量分数作为路由转发路径对应的网络质量信息。
在某些实施方案中，可以根据下述公式计算路由转发路径对应的网络质量信息：
Z＝a*V+(1-a)*t
其中，z表示路由转发路径对应的网络质量分数，即网络质量信息，a表示用户或开发人员根据实际需求预设的传输速率的权重，v表示传输速率，t表示传输带宽。
在某些实施方案中，预设要求可以为用户或开发人员根据实际需求设定的要求，例如预设要求可以为网络质量信息不低于第一阈值，其中第一阈值为根据实际需求设定的值。
若网络质量信息不符合预设要求则表示当前目标路由转发路径对应的注册网络的网络质量不好，会影响数据的传输。比如WLAN网络，终端在移动过程中，随着与网络点的之间距离的增大，网络质量也越来越差，且不稳定，终端与WLAN网络之间的连接随时有可能会断开， 这也就导致随时有可能出现数据传输中断的问题。
在某些实施方案中，为了保证数据传输不中断，在网络质量信息不符合预设要求时，获取当前时刻可用的其他网络接口对应的网络质量信息，以便根据网络质量信息选取一个可替换的网络。网络接口对应的网络质量信息也可以根据网络接口对应的注册网络的传输速率和传输带宽来确定，参见S14中所述的网络质量信息计算方法，此处不再赘述。
在某些实施方案中，可以在网络质量信息符合预设要求的网络接口中随机选取一个作为替换网络接口。
在某些实施方案中，确定当前时刻可用的网络接口中网络质量信息符合预设要求的网络接口作为备选网络接口，从备选网络接口中选取网络质量信息最优的，作为替换网络接口。
在某些实施方案中，选取网络质量最优的网络接口作为替换网络接口，可以保证有目标网络接口切换至替换网络接口后，数据传输速度较快。
在某些实施方案中，确定当前时刻可用的网络接口中网络质量信息符合预设要求的网络接口作为备选网络接口，从备选网络接口中选取预设的优先级最高的，作为替换网络接口。
在某些实施方案中，网络接口的优先级通常在设置时，是有一定依据的，例如按照所需费用由低到高进行设置，费用越低，优先级越高，因此选取优先级最高的网络接口作为替换网络接口，可以保证数据传输所消耗的费用较低。
