具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施方式。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本申请的公开内容理解的更加透彻全面。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。
本申请实施例中的终端设备可以指用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiationprotocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是LTE系统中的演进型基站(evolutional nodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1为一种通信系统的示例，如图1所示，该通信系统包括终端设备、路由器以及通信模组。路由器包括LAN端口、中央处理器(central processing unit，CPU)和WAN端口。终端设备与该LAN端口连接，通信模组与该WAN端口连接。例如，终端设备可以通过网线或WIFI与该LAN端口连接，通信模组可以通过USB与该WAN端口连接。终端设备通过网线或WIFI将数据包发送到路由器的LAN端口。路由器通过该LAN端口接收到终端设备发送的数据包之后，可以通过CPU对该数据包进行处理和转发，并通过WAN端口将处理后的数据包转发至通信模组。例如，LAN端口接收到数据包之后，将该数据包传输至路由器的CPU，由路由器的CPU对该数据包进行处理，CPU将处理后的数据包传输至WAN端口，由该WAN端口将该数据包发送至通信模组。通信模组接收到该处理后的数据包之后，将该处理后的数 据包发送至因特网(internet)。
示例性地，路由器上配置有广域网网络协议(Internet Protocol，IP)地址。终端设备在接入该路由器时，可以获取到路由器分配的局域网IP地址。终端设备基于该局域网IP地址对数据包进行封装，终端设备向路由器发送的数据包中包括该局域网IP地址。路由器在接收到终端设备发送的数据包之后，需要对该数据包进行解包，以便于路由器可以获取到该数据包的目的IP地址。路由器获取到该数据包的目的IP地址之后，利用该路由器的广域网IP地址对该数据包进行封装，以便于该数据包可以路由到正确的接收端。
可理解，上述路由器可以与多个终端设备连接，接收多个终端设备发送的数据包。路由器对数据包的解包与封装的过程中，需要经过传输控制协议/网际协议(transmission control protocol/internet protocol，TCP/IP)协议栈处理。在有多个终端设备进行数据包并发的情况下，路由器接收到大量数据包，需要对多个数据包进行处理，使得路由器的负担重。在该通信系统中，数据包的传输速率依赖于路由器的处理能力以及路由器的带宽。例如在多个终端设备需要传输数据的情况下，会因为路由器的带宽不足而导致数据传输速率不高。例如，在4G通信系统中，由于网络传输速率不高，因此在多个终端设备进行数据包并发的情况下不会发生因路由器的处理能力不足而导致的传输速率不高的情况，即在4G通信系统中，路由器的处理能力对数据传输速率的影响较小。而5G通信系统中的网络传输速率大于4G通信系统中的网络传输速率，因此在5G通信系统，数据的传输速率受到路由器的处理能力的影响较大，可能会出现因路由器的处理能力不足而导致的数据传输速率不高的情况。
基于此，本申请实施例提供一种数据转发装置、方法、电子设备及存储介质，能够解决路由器的负担重，以及由于路由器的处理能力而导致的数据传输速率不高的问题。

示例性地，上述拨号链路可以为公用数据网(public data network，PDN)拨号链路，上述通信模组支持多PDN拨号。
示例性地，路由器220和通信模组210可以支持高通多路复用和聚合(qualcomm multiplexing and aggregation，QMAP)协议。路由器220和通信模组210可以基于该QMAP协议进行多路拨号。
示例性地，路由器220可以通过AT(Attention)指令或者高通消息接口(qualcomm message interface，QMI)的方式进行拨号，上述至少一个虚拟网卡可以配置在路由器220的QMI_WWAN驱动中。AT指令是应用于终端设备与计算机应用之间的连接与通信的指令。QMI_WWAN驱动是Linux上高通模块的驱动程序，负责路由器220与通信模组210之间数据通路的建立，支持QMI拨号。示例性地，上述拨号链路拨号后，路由器220可以将广域网IP地址配置到虚拟网卡221上，建立该拨号链路与虚拟网卡221之间的数据通路，该虚拟网卡221可以访问到广域网。
本申请实施例中，通信模组支持多路拨号，路由器可以包括虚拟网卡与网络接口，其中虚拟网卡与网络接口通过网桥连接。网络接口在接收到终端设备发送的第一数据包之后，通过网桥将该第一数据包转发至虚拟网卡，虚拟网卡再将该第一数据包转发至通信模组，通信模组通过虚拟网卡对应的拨号链路将该第一数据包转发至网络设备。通过将虚拟网卡与网络接口桥接，使得网络接口接收到的第一数据包可以直接传输到虚拟网卡，从而提高该第一数据包的传输速率。
在一种可能的实施方式中，所述第一数据包包括广域网网络协议IP地址，所述路由器220还包括IP地址分配模块224；
所述网络接口222还用于接收所述终端设备发送的连接请求；
所述IP地址分配模块224用于将所述广域网IP地址分配至所述终端设备。
示例性地，该广域网IP地址为终端设备在接入该路由器220时路由器220为终端设备分配的。在终端设备接入该路由器220时，路由器220可以为该终端设备分配该广域网IP地址，使得终端设备可以基于该广域网IP地址进行数据包的发送和接收。终端设备基于该广域网IP地址将数据进行封装得到上述第一数据包，并将该第一数据包发送至网络接口222。路由器220可以通过网络接口222接收该第一数据包。
示例性地，在终端设备接入路由器220时，终端设备可以向路由器220发送连接请求。例如，终端设备可以向路由器220发送拨号请求，以获取IP地址。
路由器220在通过网络接口222接收到终端设备的连接请求的情况下，通过IP地址分配模块224将广域网IP地址分配至终端设备，以便于终端设备可以基于该广域网IP地址接入到广域网。
示例性地，IP地址分配模块224中包括广域网IP地址集合，IP地址分配模块224可以 对广域网IP地址集合中的广域网IP地址进行管理和分配。在广域网IP地址集合中存在未分配的广域网IP地址的情况下，上述广域网IP地址为该未分配的广域网IP地址中的任一个。
示例性地，网络接口222接收到终端设备发送的连接请求之后，若上述广域网IP地址集合中不存在未分配的广域网IP地址，上述IP地址分配模块224可以向通信模组210发送拨号请求，该拨号请求用于向该通信模组210请求广域网IP地址。通信模组210在接收到该拨号请求后，向网络设备发送拨号请求，以向网络设备获取广域网IP地址。
通信模组210接收网络设备返回的广域网IP地址，并将该广域网IP地址转发至该IP地址分配模块224。IP地址分配模块224接收图像模组转发的广域网IP地址后，将该广域网IP地址分配至终端设备，使得终端设备能够连接到网络。
示例性地，上述通信模组210可以向网络设备发起多路拨号请求，以获取多个广域网IP地址。
可选地，IP地址分配模块224在上述广域网IP地址集合中不存在未分配的情况下，可以发起多路拨号请求，该多路拨号请求用于向通信模组210请求多个广域网IP地址。通信模组210接收到该多路拨号请求之后，向网络设备发起多路拨号请求，获取多个广域网IP地址，并该多个广域网IP地址返回至IP地址分配模块224。相应的，IP地址分配模块224接收该多个广域网IP地址。IP地址分配模块224可以通过多路拨号请求，获取多个广域网IP地址，以便于在终端设备接入时可以快速地将广域网IP地址分配到对应的终端设备上，而无需频繁地向通信模组210发送拨号请求，提高广域网IP地址分配的效率，使得终端设备可以快速接入网络，同时也节省了IP地址分配模块224多次发起拨号请求所占用的资源。
可理解，上述广域网IP地址集合中的广域网IP地址可以是IP地址分配模块224预先获取到的，例如，路由器220在连接到通信模组210时，或者路由器220在开机时，IP地址分配模块224可以向通信模组210发送多路拨号请求，获取多个广域网IP地址，以便于在有终端设备接入时能够快速地为该终端设备分配广域网IP地址。
可理解，上述IP地址分配模块224可以通过路由器220的通信模块向通信模组210发送拨号请求以及接收通信模组210返回的广域网IP地址。该通信模块可以集成于该IP地址分配模块224中，也可以集成于路由器220中并与该IP地址分配模块224连接，本申请不做限定。
本申请实施例中，终端设备可以通过该网络接口与路由器连接，终端设备可以通过网络接口向路由器发送连接请求，从而接入到该路由器。上述数据转发装置通过网络接口接收到终端设备发送的连接请求的情况下，将广域网IP地址分配至终端设备，使得该终端设备可以利用该广域网IP地址发送该第一数据包。路由器通过网络接口接收到该第一数据包后无需再对第一数据包进行IP地址的转换，使得第一数据包可以绕过TCP/IP协议栈直接传输到对应的拨号链路，从而减轻了路由器CPU的负担，提高该第一数据包的传输效率。

本申请实施例中，在路由器的广域网IP地址集合中不存在未分配的广域网IP地址的情况下，路由器可以向通信模组发送拨号请求，以获取到广域网IP地址，从而保证能够为该终端设备或虚拟网卡分配广域网IP地址，使得该终端设备能够连接到网络。
在一种可能的实现方式中，图4所示的数据转发方法还可以包括如下步骤：
403，虚拟网卡接收通信模组发送的第二数据包，并通过网桥将第二数据包传输至网络接口。
404，网络接口将第二数据包转发至终端设备。
本申请实施例中，路由器可以通过虚拟网卡接收该通信模组发送的第二数据包，再通过网桥将该第二数据包传输至网络接口，由该网络接口将该第二数据包转发至终端设备。通过网桥将虚拟网卡与网络接口桥接，在通过虚拟网卡接收到通信模组转发的第二数据包之后，可以直接通过网桥将该第二数据包传输至该网络接口，从而提高该第二数据包的传输效率。
