需要说明的是：不需要由网络业务节点处理的字段包括所述字段对于网络业务节点来说是可以处理的，但是为了简化网络业务节点，网络业务节点对所述字段不进行处理，由其他设备比如适配器对所述字段进行处理。It should be noted that the field that does not need to be processed by the network service node includes the field that can be processed by the network service node, but in order to simplify the network service node, the network service node does not process the field, and other devices For example, the adapter processes the field.

由上可见，通过适配器对要发送到网络业务节点的第一报文进行处理后，形成网络业务节点可以处理的第二报文，使得网络业务节点可以聚焦于业务处理，简化了网络业务节点。It can be seen that after the first packet to be sent to the network service node is processed by the adapter, the second packet that can be processed by the network service node is formed, so that the network service node can focus on the service processing and simplify the network service node.

图16为图15所示网络业务处理***对图13所示结构的报文进行网络业务处理时，网络设备61、网络业务控制器62、网络中转设备63、适配器64和网络业务节点65的交互流程示意图，主要包括：16 is an interaction between the network device 61, the network service controller 62, the network relay device 63, the adapter 64, and the network service node 65 when the network service processing system shown in FIG. 15 performs network service processing on the packet of the structure shown in FIG. The schematic diagram of the process mainly includes:

S601、网络业务控制器62向网络中转设备63发送转发规则；S601. The network service controller 62 sends a forwarding rule to the network relay device 63.

具体地，在本实施例中，所述转发规则包括：将网络设备61发来的VLAN ID的值为100的报文转发到适配器64、将适配器64发来的且没有VLAN ID字段的报文转发到网络业务节点65、将从网络业务节点65发来的返回报文转发到适配器64、将由适配器64发来的且VLAN ID的值为100的报文转发给网络设备61；Specifically, in this embodiment, the forwarding rule includes: forwarding a packet with a VLAN ID value of 100 sent by the network device 61 to the adapter 64, and sending the packet with the adapter 64 without the VLAN ID field. Forwarding to the network service node 65, forwarding the return message sent from the network service node 65 to the adapter 64, forwarding the packet sent by the adapter 64 and having a VLAN ID of 100 to the network device 61;

S602、网络业务控制器62向适配器64发送适配规则；S602. The network service controller 62 sends an adaptation rule to the adapter 64.

S603、网络设备61将包含VLAN ID字段且VLAN ID的值为100的第一报文发送到网络中转设备63；S603, the network device 61 sends a first packet containing a VLAN ID field and a VLAN ID value of 100 to the network relay device 63;

S604、网络中转设备63将接收的第一报文发送到适配器64；S604, the network relay device 63 sends the received first message to the adapter 64;

S605、适配器64根据适配规则对第一报文进行处理，生成第二报文；S605. The adapter 64 processes the first packet according to the adaptation rule to generate a second packet.

具体地，根据第一次适配规则，删除报文中的VLAN ID字段；Specifically, the VLAN ID field in the packet is deleted according to the first adaptation rule.

S606、适配器64将第二报文发送到网络中转设备63； S606, the adapter 64 sends the second message to the network relay device 63;

S607、网络中转设备63将第二报文转发到网络业务节点65；S607, the network relay device 63 forwards the second packet to the network service node 65;

S608、网络业务节点65对接收到的第二报文进行业务处理，生成返回报文；S608. The network service node 65 performs service processing on the received second packet to generate a return packet.

S609、网络业务节点65将返回报文发送到网络中转设备63；S609, the network service node 65 sends the return message to the network relay device 63;

S610、网络中转设备63将返回报文发送到适配器64；S610, the network relay device 63 sends a return message to the adapter 64;

S611、适配器64根据适配规则对返回报文进行第二次处理，生成第三报文；S611. The adapter 64 performs a second processing on the returned packet according to the adaptation rule to generate a third packet.

S612、适配器64将第三报文发送到网络中转设备63；S612, the adapter 64 sends the third message to the network relay device 63;

S613、网络中转设备63将第三报文发送到网络设备61。S613. The network relay device 63 sends the third packet to the network device 61.

需要说明的是，上述各步骤进行数据传输时，还可以进一步地包括中转步骤，比如网络业务控制器62向适配器64发送适配规则的步骤，其中的适配规则可以不是网络业务控制器62直接发送到适配器64，而是网络业务控制器62先把适配规则发给一个中转装置，比如网络控制器，然后由网络控制器将适配规则转发到适配器64。网络控制器可以是网管***或Openflow控制器等。It should be noted that, when the foregoing steps perform data transmission, the method further includes a transit step, such as the step of the network service controller 62 sending an adaptation rule to the adapter 64, where the adaptation rule may not be directly the network service controller 62. Sended to adapter 64, network service controller 62 first sends the adaptation rules to a relay device, such as a network controller, which then forwards the adaptation rules to adapter 64. The network controller can be a network management system or an Openflow controller.

由上可见，通过适配器对要发送到网络业务节点的第一报文进行处理形成网络业务节点可以处理的第二报文，使得网络业务节点可以聚焦于业务处理。It can be seen that the first packet to be sent to the network service node is processed by the adapter to form a second packet that can be processed by the network service node, so that the network service node can focus on the service processing.

请参阅图17，图17为图6所示网络业务处理***进行网络业务处理时的另一交互流程示意图。在该实施例中，网络业务节点33具有如下特点：网络业务节点33进行业务处理时，在报文中必须要有VLAN ID字段，网络业务节点33才能进行业务处理。在该实施例中由网络设备31发送的第一报文中不包括VLAN ID字段。具体流程包括如下步骤：Please refer to FIG. 17. FIG. 17 is a schematic diagram of another interaction process when the network service processing system shown in FIG. 6 performs network service processing. In this embodiment, the network service node 33 has the following characteristics: When the network service node 33 performs service processing, the VLAN ID field must be present in the packet, and the network service node 33 can perform service processing. The VLAN ID field is not included in the first message sent by the network device 31 in this embodiment. The specific process includes the following steps:

S701、网络业务控制器32向适配器34发送适配规则；S701. The network service controller 32 sends an adaptation rule to the adapter 34.

所述适配规则包括，第一适配规则和第二适配规则。其中第一适配规则包括：根据网络业务节点33的特性，当网络设备31发送给适配器34的第一报文不包含VLAN ID字段时，在第一报文中添加VLAN ID字段；第二适配规则包括：在返回报文中删除在第一适配规则中添加的VLAN ID字段。The adaptation rule includes a first adaptation rule and a second adaptation rule. The first adaptation rule includes: adding, according to the characteristics of the network service node 33, the VLAN ID field in the first packet when the first packet sent by the network device 31 to the adapter 34 does not include the VLAN ID field; The matching rule includes: deleting the VLAN ID field added in the first adaptation rule in the return message.

S702、网络设备31向适配器34发送第一报文；所述第一报文中的字段不报VLAN ID字段；S702. The network device 31 sends a first packet to the adapter 34. The field in the first packet does not report the VLAN ID field.

S703、适配器34根据第一适配规则在第一报文中添加VLAN ID字段，生成第二报文；S703. The adapter 34 adds a VLAN ID field to the first packet according to the first adaptation rule. Into the second message;

S704、适配器34将所述第二报文发送给网络业务节点33；S704, the adapter 34 sends the second packet to the network service node 33;

S705、网络业务节点33对第二报文进行业务处理，生成返回报文；S705: The network service node 33 performs service processing on the second packet to generate a return packet.

S706、网络业务节点33将返回报文发送给适配器34；S706, the network service node 33 sends the return message to the adapter 34;

S707、适配器34根据第二适配规则在返回报文中删除在第一适配规则中添加的VLAN ID字段，生成第三报文；S707. The adapter 34 deletes the VLAN ID field added in the first adaptation rule in the return packet according to the second adaptation rule, to generate a third packet.

S708、适配器34将第三报文发送到网络设备31。S708. The adapter 34 sends the third message to the network device 31.

本实施例通过在第一报文中添加第一报文中缺少的且网络业务节点进行业务处理时必须要有的字段，使得经过处理后的第二报文成为网络业务节点可以处理的报文，使得网络业务节点可以聚焦于业务处理。In this embodiment, a field that is required in the first packet and that is required to be processed by the network service node is added in the first packet, so that the processed second packet becomes a packet that can be processed by the network service node. So that network service nodes can focus on business processing.
