Refer to Fig. 5, Fig. 5 is the structure composition schematic diagram of another embodiment of adapter of the present invention.Described embodiment comprises at least one receiver, processor and transmitting element, and wherein said receiver is identical with the function of the 3rd receiver module 25 with the first receiver module 21, second receiver module 24, does not repeat at this.Processor is identical with the function of the second processing module 26 with the first processing module 22, does not repeat at this.Transmitting element in the present embodiment is identical with the function of the second transmitting element 27 with the first transmitting element 23, does not repeat at this.
Particularly, the first message that in the present embodiment, receiver sends for receiving the network equipment, and the adaptation rule that network service controlling device sends, processor processes according to adaptation rule the first message that receiver receives, and manageable for the network service node after processor process the second message is sent to network service node by transmitting element.When network service node produces returned packet, receiving element reception returned packet is dealt into processor and carries out processing the 3rd message obtaining forwarding for transmitting element, and the 3rd message is forwarded to the network equipment by transmitting element.
Therefore, by adapter, process is carried out to the message that will be sent to network service node and form manageable second message of network service node, make network service node to focus on Business Processing, simplify network service node.
The structural representation of a kind of Network treatment system that Fig. 6 provides for the embodiment of the present invention.This Network treatment system 3 comprises:
The network equipment 31, network service controlling device 32, network service node 33 and adapter 34, wherein,
The described network equipment 31, for sending the first message to described adapter 34;
Described network service controlling device 32, for sending adaptation rule to described adapter 34;
Described network service node 33, carries out Business Processing to the first message according to the second message formed after adaptation rule process for what send described adapter 34;
Described adapter 34, for receive send from the network equipment 31 the first message, receive send from network service controlling device 32 adaptation rule, according to described adaptation rule, process is carried out to the first message and forms network service node 33 accessible second message, and send to network service node 33 to carry out Business Processing described second message.
Further, described network service node 33, also generates returned packet after carrying out Business Processing to the second message, and returned packet is sent to described adapter 34;
Described adapter 34, also for receive generate after network service node 33 carries out Business Processing returned packet, described returned packet carried out process form the 3rd message that forwards for adapter and by the 3rd message repeating to the network equipment 31, it should be noted that the network equipment that the 3rd message repeating arrives can be the same network equipment with the network equipment of transmission the first message, also can be the different network equipments.
Further, described Network treatment system can also comprise network transferring equipment:
Described network transferring equipment, for receiving the second message after the first time process of described adapter, and is transmitted to described network service node by this second message.
Described adapter is also for sending to network transferring equipment by accessible first message of network service node after described first time process.
Further, described adapter, also for the 3rd message after second time process is sent to network transferring equipment;
Described network transferring equipment, also for receiving the 3rd message that described adapter sends, and by the 3rd message repeating to the network equipment.
Therefore, by adapter, first time process is carried out to the message that will be sent to network service node and form the manageable message of network service node, make network service node to focus on Business Processing, simplify network service node.
In another embodiment, message as shown in Figure 7, comprises field SR, and wherein SR is a data structure, specific as follows:
Struc service_routing_header{
Uint16id；
Uint16resv;
}_packed;
Fig. 8 for the treatment system of Network shown in Fig. 6 Network process is carried out to the message of structure shown in Fig. 7 time, the interaction flow schematic diagram of the network equipment 31, network service controlling device 32, adapter 34 and network service node 33, comprises the steps:
S301, network service controlling device 32 send adaptation rule to adapter 34;
Particularly, in this embodiment, suppose the field that SR field belongs to needs and shields to network service node that is: to make network service node can't see SR field.Described adaptation rule comprises the first adaptation rule and the second adaptation rule.First adaptation rule comprises the SR field in deletion first message; Second adaptation rule is included in returned packet and adds SR field.
S302, the network equipment 31 are to the first message of adapter 34 transmit band service identification;
Particularly, as described in Figure 7, to described first message SR field wherein need the field to network service node shielding.
S303, adapter 34 carry out process according to described adaptation rule to the first message and form accessible second message of network service node;
Particularly, adapter 34 deletes the SR field in message according to the first adaptation rule, and the message deleted after SR field is manageable second message of network service node 33.
Described second message sends to described network service node 33 to carry out Business Processing by S304, adapter 34.
S305, network service node 33 carry out Business Processing to the second message received, and generate returned packet;
Returned packet is sent to adapter 34 by S306, network service node 33;
S307, adapter 34 process returned packet according to adaptation rule, generate the 3rd message being used for adapter and carrying out forwarding;
Particularly, SR field is added in returned packet according to the second adaptation rule by adapter 34.
3rd message is sent to the network equipment 31 by S308, adapter 34.
It should be noted that, when above steps carries out transfer of data, go to step in can also comprising further, such as network service controlling device 32 sends the step of adaptation rule to adapter 34, adaptation rule wherein can not be that network service controlling device 32 is directly sent to adapter 34, but network service controlling device 32 first issues transferring device, such as a network controller adaptation rule, then by network controller, adaptation rule is forwarded to adapter 34.Network controller can be network management system or Openflow controller etc.
Therefore, by adapter, first time process is carried out to first message that will be sent to network service node and form manageable second message of network service node, make network service node to focus on Business Processing, simplify network service node.
Referring to Figure 10, is the structural representation of the first message in another embodiment, and in this embodiment, supposing that source MAC field and object MAC field belong to does not need to carry out by network service node the field that processes.
It should be noted that: do not need by the field of network service node process, it is manageable for comprising described field for network service node, but in order to simplified network service node, network service node does not process described field, is processed described field by other equipment such as adapter.
In this embodiment, described source MAC field and object MAC field are manageable for network service node, but in order to simplified network service node, have been come to the process of source MAC field and object MAC field by adapter.
Figure 11 for the treatment system of Network shown in Fig. 9 Network process is carried out to the message of structure shown in Figure 10 time, the interaction flow schematic diagram of the network equipment 41, network service controlling device 42, network service node 43, adapter 44 and network transferring equipment 45, mainly comprises:
