具体实施方式
图1为本申请实施例提供的一种应用场景的示意图，如图1所示，本实施例的应用场景中包括：至少一个终端设备、物理网关设备、转发设备、服务器。其中，图1中以两个终端设备为例示出，且以一个终端设备为手机，另一个终端设备为电脑为例子示出，但是本实施例并不限于此，另外，本实施例中的至少一个终端设备可以均为手机或者电脑等。图1中以物理网关设备为物理家庭网关(Physical Residence Gateway，PRG)为例示出，且至少一个终端设备与PRG处于同一家庭网络中。另外，本实施例中的该服务器设置在云端，可以称为云服务器，而且该服务器中可以配置虚拟家庭网关(Virtual Residence Gateway，VRG)。其中，图1中示出手机的数据经由VRG进行增值业务处理，而电脑的数据无需经由VRG进行增值业务处理。其中，增值业务处理包括但不限于：绿色上网过滤、视频加速等。
结合图1所示的应用场景，对本申请的方案进行描述。
图2为本申请一实施例提供的报文转发控制方法的流程图，如图2所示，本实施例的方法可以包括：
S201、服务器接收增值业务请求。
本实施例中，服务器接收到增值业务请求，该增值业务请求包括终端设备的标识信息，该增值业务请求用于请求该终端设备的数据需要进行增值业务处理。其中，该标识信息用于区分不同的终端设备，例如：该标识信息可以包括以下至少一项：终端设备的MAC地址，用户名，账号等。需要说明的是，该增值业务请求也可以包括多个不同终端设备的标识信息，这表示增值业务请求用于请求该多个不同终端设备也需要进行增值业务处理，每个终端设备与参见下述终端设备的实现方案类似，此处不再赘述。
其中，服务器接收增值业务请求的一种方式为：用户通过一个终端设备(需要说明的是，该终端设备可以是需要进行增值业务处理的终端设备，也可以不是，甚至该终端设备也可以不是该家庭网络中的终端设备)连接到服务器(例如运营商的网页)，该运营商的网页中显示有增值业务处理选项，用户通过操作终端设备在该网页中输入需要进行增值业务处理的终端设备的标识信息，从而使得服务器可以接收到增值业务请求。
S202、所述服务器根据所述增值业务请求，为与所述终端设备连接的PRG分配网关地址，并生成数据转发策略。
本实施例中，服务器接收到增值业务请求之后，确定该终端设备的数据需要经由虚拟网关设备进行增值业务处理，因此，需要为与该终端设备连接的PRG分配网关地址，使得PRG为该终端设备的报文封装该网关地址时，该终端设备的数据可以转发至VRG进行增值业务处理，该网关地址也可以认为是VRG的网关地址。所以，本实施例的服务器可以从地址池中为与该终端设备连接的PRG分配网关地址，然后根据该网关地址，生成数据转发策略。其中，该数据转发策略包括：分配的该网关地址以及该终端设备的标识信息，并且数据转发策略用于指示该终端设备的数据需要根据该网关地址转发至虚拟网关设备进行增值业务处理。
S203、服务器向PRG发送所述数据转发策略。
本实施例中，服务器在分配网关地址和生成数据转发策略之后，向与该终端设备连接的PRG发送上述的数据转发策略。相应地，PRG接收到服务器发送的数据转发策略，PRG可以确定该PRG的其中一个网关地址为接收的网关地址，并且根据该数据转发策略可以确定该终端设备的数据需要封装该网关地址，以便转发至虚拟网关设备进行增值业务处理。
在一些实施例中，服务器向PRG发送DHCP消息，所述DHCP消息包括所述数据转发策略。相应地，PRG接收服务器发送的DHCP消息，从DHCP消息获取所述数据转发策略。在一些实施例中，所述数据转发策略包括在所述DHCP消息的选项字段中，例如如下所示，数据转发策略包括如下所述的Acl rule1，即表示MAC地址为0011-1111-1111的终端设备的数据需要根据网关地址为11.11.11.11进行增值业务处理。
Option(XX)pRG NFV Service
Length：XXX
Acl rule1：MAC＝＝0011-1111-1111
Gateway：11.11.11.11
在一些实施例中，服务器向PRG发送PPPOE消息，所述PPPOE消息包括所述数据转发策略。相应地，PRG接收服务器发送的PPPOE消息，从PPPOE消息获取所述数据转发策略。
S204、PRG接收终端设备发送的报文。
S205、PRG根据所述报文中的所述终端设备的标识信息以及所述数据转发策略，确定所述终端设备的标识信息对应的所述网关地址。
本实施例中，PRG接收终端设备发送的报文，而且该终端设备为数据转发策略中指示的数据需要进行增值业务处理的终端设备，例如：该报文中包括发送该报文的终端设备的标识信息，如果该报文中包括的终端设备的标识信息与数据转发策略中指示的终端设备的标识信息相同，则PRG确定该报文中的数据需要进行增值业务处理。然后，PRG根据该终端设备的标识信息以及该数据转发策略，确定该终端设备对应的网关地址。
S206、PRG根据所述网关地址，发送所述报文。
本实施例中，PRG根据该网关地址，发送所述报文，使得该报文转发至VRG进行增值业务处理。
本实施例中，服务器在接收到增值业务请求后，分配网关地址并生成数据转发策略，并将该数据转发策略发送给终端设备连接的PRG，由PRG在接收到该终端设备发送的报文后，基于该数据转发策略，根据该网关地址发送所述报文，实现了终端设备的数据可被转发至VRG进行增值业务处理，并且，本实施例中的数据转发策略无需用户人工在PRG上进行配置，而是服务器下发给PRG的，因此，提高了数据转发策略配置效率。
图3为本申请另一实施例提供的报文转发控制方法的流程图，如图3所示，本实施例以服务器为DHCP服务器为例，本实施例的方法可以包括：
S301、DHCP服务器接收增值业务请求。
S302、所述DHCP服务器根据所述增值业务请求，为与所述终端设备连接的PRG分配网关地址，并生成数据转发策略。
本实施例中，S301和S302的具体实现过程可以参见图2所示实施例中的相关描述，此处不再赘述。
S303、所述DHCP服务器建立所述网关地址与处理所述增值业务的VRG之间的对应关系。
本实施例中，DHCP服务器还建立该网关地址与处理该增值业务的VRG之间的对应关系，以便DHCP服务器在接收到封装有该网关地址的报文时，根据该对应关系，由该VRG对该报文进行增值业务处理。
本实施例中，DHCP服务器为PRG分配网关地址并生成数据转发策略之后，在一些实施例中，DHCP服务器可以主动向PRG下发数据转发策略。而在另一些实施例中，DHCP服务器可以在接收PRG发送的请求之后再下发数据转发策略，具体实现过程可以见如下所述。
S304、DHCP服务器向所述PRG发送DHCP强制更新消息。
本实施例中，DHCP服务器向PRG发送第一消息，该第一消息用于指示所述PRG重新申请网关地址。相应地，PRG接收到DHCP服务器发送的第一消息，根据该第一消息，确定需要重新申请网关地址。
在一些实施例中，上述的第一消息为DHCP强制更新消息(DHCP force renew消息)。
S305、PRG根据DHCP强制更新消息，向DHCP服务器发送DHCP请求消息。
本实施例中，PRG根据第一消息，确定需要重新申请网关地址后，向服务器发送第二消息，该第二消息用于请求该PRG的网关地址。
在一些实施例中，上述的第二消息为DHCP请求消息(DHCP request消息)。
S306、DHCP服务器根据DHCP请求消息，向PRG发送DHCP应答消息。
本实施例中，DHCP服务器根据接收的第二消息(例如DHCP request消息)，确定需要向PRG发送分配的网关地址。然后DHCP服务器向PRG发送数据转发策略，在一些实施例中，DHCP服务器向PRG发送DHCP应答消息(DHCP offer消息)，该DHCP offer消息包括数据转发策略。
S307、PRG接收终端设备发送的报文。
S308、PRG根据所述报文中的所述终端设备的标识信息以及所述数据转发策略，确定所述终端设备的标识信息对应的所述网关地址。
本实施例中，S307和S308的具体实现过程可以参见图2所示实施例中的相关描述，此处不再赘述。
S309、PRG将所述网关地址封装在所述报文中，发送封装所述网关地址的报文。
本实施例中，PRG在确定该终端设备的标识信息对应的网关地址之后，将所述网关地址封装在所述报文中，并发送封装所述网关地址的报文。由于该报文中封装有所述网关地址，因此，该报文会被转发设备转发至云端的DHCP服务器中。
S310、所述DHCP服务器接收封装所述网关地址的报文。
S311、所述DHCP服务器根据所述报文中封装的网关地址，以及网关地址与处理增值业务的VRG之间的对应关系，确定所述网关地址对应的处理所述增值业务的VRG。
本实施例中，服务器接收封装所述网关地址的报文，根据该报文中封装的网关地址，以及DHCP服务器建立的网关地址与处理增值业务的VRG之间的对应关系，确定该网关地址对应的处理增值业务的VRG。
S312、所述DHCP服务器控制所述VRG对所述报文进行增值业务处理。
本实施例中，VRG是设置在DHCP服务器上的虚拟网关设备，因此，DHCP服务器可以控制VRG对该报文进行增值业务处理，在完成增值业务处理之后，DHCP服务器发送该增值业务处理后的报文，例如发送至转发设备，由转发设备发送至互联网等。
本实施例中，DHCP服务器在接收到增值业务请求后，分配网关地址并生成数据转发策略，并将数据转发策略包括在DHCP消息中发送给终端设备连接的PRG，由PRG在接收到该终端设备发送的报文后，根据该网关地址发送所述报文，实现了终端设备的数据可被转发至VRG进行增值业务处理，并且，本实施例中的数据转发策略无需用户人工在PRG上进行配置，另外，数据转发策略包括在DHCP消息的选项字段中，因此，数据转发策略可以通过DHCP消息由DHCP服务器下发给PRG，从而提高了数据转发策略配置效率。
在上述各实施例的基础上，如果家庭网络中包括：N个终端设备，N为大于1的整数，而数据需要进行增值业务处理的终端设备的个数为N1个，而数据不需要进行增值业务处理的终端设备的个数为N2个，N1+N2＝N，N1和N2分别为大于0的整数。若以上述各实施例中服务器为PRG分配的网关地址称为第一网关地址，则服务器根据该N1个终端设备为PRG分配第一网关地址。由于N2个终端设备的数据不需要进行增值业务处理，因此，服务器还根据N2个终端设备为PRG分配网关地址，该网关地址称为第二网关地址，并将该第二网关地址发送给PRG，该N2个终端设备的报文根据该第二网关地址转发时不会被转发至VRG进行增值业务处理。由此可知，服务器为PRG分配了两个网关地址，一个为第一网关地址，另一个为第二网关地址，其中，该第一网关地址与N1个终端设备对应，该第二网关地址与N2个终端设备对应，而且，服务器发送给PRG的该数据转发策略中还包括第二网关地址以及该N2个终端设备的标识信息，并且该数据转发策略还用于指示不需要进行增值业务处理的终端设备的数 据根据所述第二网关地址转发。如果PRG接收的报文是N1个终端设备中任一终端设备发送的，则PRG根据第一网关地址转发该报文，则该报文会被转发至VRG进行增值业务处理。如果PRG接收的报文是N2个终端设备中任一终端设备发送的，则PRG根据第二网关地址转发该报文，则该报文不会被转发至VRG进行增值业务处理。
其中，举例来说，PRG连接了两个终端设备，一个终端设备的MAC地址为0011-1111-1111，另一个终端设备的MAC地址为0022-2222-2222，其中，MAC地址为0011-1111-1111的终端设备的数据需要进行增值业务处理，例如绿色上网过滤。而MAC地址为0022-2222-2222的终端设备的数据不需要进行增值业务处理。在服务器接收到增值业务请求之后，该增值业务请求用于请求MAC地址为0011-1111-1111的终端设备需要进行增值业务处理，根据MAC地址为0011-1111-1111的终端设备，为该PRG分配网关地址为11.11.11.11，该11.11.11.11为上述的第一网关地址，并建立该网关地址11.11.11.11与处理增值业务处理的VRG之间的对应关系。另外，PRG还连接MAC地址为0022-2222-2222的终端设备，而且MAC地址为0022-2222-2222的终端设备不需要进行增值业务处理，服务器根据该MAC地址为0022-2222-2222的终端设备，还为PRG分配网关地址22.22.22.22，该22.22.22.22为上述的第二网关地址。因此，服务器为PRG分配的网关地址为两个，而且网关地址11.11.11.11用于转发MAC地址为0011-1111-1111的终端设备的数据，网关地址22.22.22.22用于转发MAC地址为0022-2222-2222的终端设备的数据。然后，服务器向PRG发送数据转发策略，该数据转发策略包括：MAC地址0011-1111-1111和0022-2222-2222，网关地址11.11.11.11和22.22.22.22，并且该数据转发策略用于指示MAC地址0011-1111-1111的终端设备的数据根据网关地址11.11.11.11转发至VRG进行增值业务处理，以及MAC地址0022-2222-2222的终端设备的数据根据网关地址22.22.22.22转发。其中，该数据转发策略可以包括在DHCP消息中，例如如下所示：
Option(XX)pRG NFV Service
Length：XXX
Acl rule1：MAC＝＝0011-1111-1111
Gateway：11.11.11.11
Acl rule2：MAC＝＝0022-2222-2222
Gateway：22.22.22.22
其中，数据转发策略包括如上所示的Acl rule1和Acl rule2。
相应地，PRG接收到数据转发策略之后，根据Acl rule1，将包括MAC地址为0011-1111-1111的报文根据网关地址为11.11.11.11进行转发，根据Acl rule2，将包括MAC地址为0022-2222-2222的报文根据网关地址为22.22.22.22进行转发。
