In embodiments of the present invention, if the application program in NFV systems needs to carry out data acceleration, application program can be with
The first data to be accelerated, when virtual accelerator receives first when data are accelerated, virtual accelerator are sent to virtual accelerator
Include the acceleration request message of the first data to be accelerated to physical accelerator transmission, so that physical accelerator treats the receiving
One when data are accelerated, can data to be accelerated to first accelerate, so as to by virtual accelerator realize NFV systems in
Data acceleration function, and then improve data-handling efficiency.
Further, when physical accelerator is according to above-mentioned steps 201-203, after obtaining first object data, if the first mesh
Mark data are destined to data in external network, then physical accelerator can be directly by network interface by first object data
It sends；If first object data are to need to return to the data of application program, physical accelerator can be by first object
Data return to the application program for sending the first data to be accelerated.
Referring to Fig. 4, if first object data are to need to return to the data of application program, after step 203, the party
Method further includes：Step 204- steps 205.
Step 204：Physical accelerator sends first object data to virtual accelerator.
Step 205：When virtual accelerator receives the first object data of physical accelerator transmission, virtual accelerator hair
Send first object data.

The equipment 3 shown.
Wherein, when the NFV include the first equipment, when virtual accelerator and physical accelerator are located in the first equipment, virtually
Accelerator and physical accelerator can directly pass through above-mentioned steps 201-203 or step 201-205 data to be accelerated to first
Accelerated.
When the NFV systems include the first equipment and the second equipment, virtual accelerator is located in the first equipment, physical accelerator
When in the second equipment, then step 202 is specifically as follows：Virtual accelerator is by accelerating network channel to be sent out to physical accelerator
Send acceleration request message.Wherein, virtual accelerator with physical accelerator by the way that network channel is accelerated to be connected.For example, as shown in Figure 6
Acceleration frame in, if physical accelerator sAEs of the virtual accelerator vAE in equipment 2 into equipment 3 sends acceleration request and disappears
Breath, then the virtual accelerator vAE in equipment 2 can pass through network accelerator nAE in equipment 2 and the network acceleration in equipment 3
Data transmission channel between device nAE, physical accelerator sAE acceleration request message being sent in equipment 3.
Correspondingly, step 204 is specifically as follows：Physical accelerator is by accelerating network channel to send the to virtual accelerator
One target data.For example, in acceleration frame as shown in Figure 6, if the physical accelerator sAE in equipment 3 is virtual into equipment 2
Accelerator vAE sends first object data, then the physical accelerator sAE in equipment 3 can pass through network accelerator in equipment 3
The data transmission channel between network accelerator nAE in nAE and equipment 2, by first object data sending in equipment 2
Virtual accelerator vAE.
In embodiments of the present invention, when virtual accelerator and physical accelerator be not in same equipment, virtual accelerator
With physical accelerator by the way that network channel is accelerated to realize transmission data acceleration function, so as to not possess physics acceleration in other equipment
In the case of device, it can also realize that the data for treating acceleration are accelerated, so as to save acceleration resource.
Further, referring to Fig. 7, before step 201, this method further includes step 200.
Step 200：Virtual accelerator, which receives, accelerates configuration information, which is used to indicate virtual accelerator and leads to
It crosses physical accelerator and carries out data acceleration.
Wherein, which can be sent to virtual accelerator by acceleration controller.The acceleration controller can
Think the acceleration controller in the NFV systems described in above-mentioned Fig. 1, which can be to have management function in MANO
Equipment.
When NFV systems include at least one virtual accelerator and at least one physical accelerator, acceleration controller can be with
For managing the binding relationship of at least one virtual accelerator and at least one physical accelerator.Wherein, acceleration controller can be with
It is sent to virtual accelerator and accelerates configuration information, which can serve to indicate that the virtual accelerator by least one
Which of a physical accelerator physical accelerator carries out data acceleration.For example, in acceleration frame as shown in Figure 6, accelerate control
Device processed can be sent to the virtual accelerator vAE in equipment 2 accelerates configuration information, which can serve to indicate that this
Virtual accelerator carries out data acceleration by the physical accelerator sAE in equipment 3.
Specifically, when virtual accelerator and physical accelerator are in same equipment (such as equipment 1 in Fig. 5), accelerate
Controller can be sent to the virtual accelerator in the equipment accelerates configuration information, can not also send acceleration configuration information.When
Virtual accelerator of the acceleration controller not into the equipment, which is sent, accelerates configuration information, which can be directly by this
Physical accelerator in equipment carries out data acceleration.
When virtual accelerator and physical accelerator be not in same equipment (such as equipment 2 and equipment 3 in Fig. 6), add
