The step of number of receiving device, the step of local CPU is objective network data distribution target memory with request, can be regardless of
Successively.
Optionally, drive module gradually can be with specific as follows to the processing procedure of CPU transmission transmission message：To local
CPU sends a transmission message, after the recovery message of CPU transmissions is received, sends message, Zhi Daoyi to CPU again
Untill the number of the transmission message of transmission reaches the number of receiving device.
In force, when the network equipment needs to send objective network data to other network equipments, the network equipment is put down
Recipient's information of objective network data can also be sent to local CPU by platform module.CPU, which can then be based on the recipient, to be believed
Breath, obtains the facility information of each receiving device, and the facility information can include the mark of receiving device, can also be set including reception
Standby address information etc..In the case of receiving device is multiple, the facility information of multiple receiving devices can be with the shape of queue
Formula is stored.
Drive module by objective network data storage in target memory after, can to CPU send one transmission message,
Address of the message of objective network data in target memory can be carried in the transmission message.CPU receives the transmission and disappeared
After breath, the transmission message can be parsed, the address wherein carried be obtained, then according to the address, from target memory
The message of objective network data is read, and then setting for the receiving device can be obtained in above-mentioned queue in the way of poll
Standby information, is then based on the facility information of receiving device got, the message is sent into corresponding receiving device.CPU will
After the message is sent, recovery message can be sent to drive module, so that drive module knows that the message is sent successfully.The recovery
The first address of target memory can be carried in message.After drive module receives the recovery message, it can be sent again to CPU
The transmission message, CPU in above-mentioned queue, in the way of poll, can then obtain mark and the address of next receiving device
Information, the message is sent to the receiving device, by that analogy.
Step 104, receive CPU and often send the recovery message sent after an objective network data.
In force, as described above, CPU is received after sending message, the transmission message can be parsed, obtains it
The address of middle carrying, then according to the address, CPU is read from target memory based on the address and sends objective network data.
After CPU sends the message, recovery message can be sent to drive module, so that drive module knows that the message is sent successfully.
The first address of target memory can be carried in the recovery message.CPU often sends an objective network data, it is possible to driving
Module sends a recovery message, and drive module can then receive the recovery message.
Step 105, when the number of the CPU received the recovery message sent is identical with the number of receiving device, release
Target memory.
In force, after drive module receives recovery message, the recovery message received can be counted, and can
After counting, to judge the number for the recovery message having been received by, if it is identical with the number of receiving device, if it is not the same,
The step of can then performing to CPU transmission transmission message；, can be according to the target memory carried in recovery message if identical
First address, call default internal memory realizing interface (such as memory management interfaces).
Optionally, be diversified to the mode that is counted of recovery message, present embodiments provide two kinds it is feasible
Processing mode：
Mode one, the number of receiving device is stored in the preset field of target memory, whenever receiving CPU transmissions
After reclaiming message, the numerical value in preset field is subtracted 1, and judges whether the result after subtracting 1 is 0, if it is, judging to receive
CPU send recovery message number it is identical with the number of receiving device.
In force, the number of receiving device can be stored in the preset field of target memory by drive module, and this is pre-
If field can be the header fields of target memory, for example uiSendCounts sends count area.In addition, the preset field
It can be other fields in above-mentioned target memory, can also be the field in other storage resources of drive module, this implementation
Example does not limit.Numerical value in the field can be used for the number (number that i.e. message needs are sent) for recording receiving device.Will
The number of receiving device is stored in the header fields of target memory, can be searched in order to drive module, improves driving mould
Block searches the efficiency of the number of receiving device, so that drive module can quickly be determined a need for continuing sending transmission and disappeared
Breath, improve the efficiency for sending network data.
It is exemplified by uiSendCounts sends count area by the field, when the system is initiated, uiSendCounts is sent out
Count area is sent to be initialized as 1, when needing to be broadcasted or during multicast, drive module can obtain the number N of receiving device,
And N is assigned to uiSendCounts and sends count area.After drive module sends message, if drive module
The recovery message of CPU transmissions is received, then the numerical value that the uiSendCounts can be sent to count area subtracts 1, and judges to subtract 1
Whether result afterwards is 0, if it is, judging the number of recovery message and the number of receiving device that the CPU received is sent
It is identical, perform step 104；If it is not, then judge the number of recovery message and the number of receiving device that the CPU received is sent
Differ, perform it is above-mentioned to CPU send send message the step of.
For example, in the presence of 5 receiving devices, counting statistics field uiSendCounts=5 is sent, whenever drive module receives
During to recovery message, it can carry out subtracting 1 operation to sending counting statistics field uiSendCounts, then judge to send counting statistics
Whether field uiSendCounts value is 0, if not 0, then illustrate it is not the 5th recovery message, not releasing memory, to CPU
Send message；Otherwise explanation is that the 5th reclaims message, releasing memory.
Based on which, one transmission counting statistics field of only increase is only needed, reduces memory requirements.
Mode two, after the recovery message of CPU transmissions is received, it is determined that the number for the recovery message having been received by, and
Whether the number for the recovery message that judgement has been received by is identical with the number of receiving device, if it is, judging the CPU received
The number of the recovery message of transmission is identical with the number of receiving device.
In force, drive module can except increase by one be used for record receiving device number preset field (i.e.
Above-mentioned transmission counting statistics field uiSendCounts) beyond, one can also be increased and be used to enter the recovery message received
The preset field that row counts.For the ease of description, the first field is can be described as recording the preset field of number of receiving device；
Preset field for being counted to the recovery message received can be the second field.First field and the second field
To be arranged in the header fields of target memory.First field and the second field are arranged in the header fields of target memory,
Can be in order to the number that drive module searches the recovery message received, and the number of receiving device, so that drive module can
Quickly to determine a need for continuing sending message, the efficiency for sending network data is improved.
When needing to be broadcasted or during multicast, drive module can obtain the number N of receiving device, and N is assigned to
First field, and be 0 by the second field initialization.After drive module sends message, if drive module receives
The recovery message sent to CPU, then can add the numerical value of the second field 1, and judge plus 1 after the second field numerical value whether
For N, if it is, judging that the number for the recovery message that the CPU received is sent is identical with the number of receiving device, step is performed
105；If it is not, then the number of recovery message and the number of receiving device that the CPU for judging to receive is sent differ, in execution
The step of stating to CPU transmission transmission message.
For example, in the presence of 5 receiving devices, the numerical value of the first field is 5, when drive module receives recovery message,
The numerical value of second field can be carried out plus 1 operates, then judge the numerical value of the second field for 5, if not 5, then illustrate it is not the 5th
Secondary recovery message, releasing memory, message is not sent to CPU；Otherwise explanation is that the 5th reclaims message, releasing memory.
Optionally, when CPU sends failure, target memory can be discharged, it is corresponding treated with offloading the CPU
Journey can be as follows：During message is sent to the CPU of local, lost if detecting that the objective network data are sent
Lose, then discharge the target memory.
In in real time, as described above, after CPU receives the transmission message, message hair can be carried out according to the transmission message
Processing is sent, however, when CPU itself processing load is overweight, CPU will be unable to send the message, and now, CPU can return to carrying
After thering is the return message of fail values, console module to detect the return message, can call default internal memory realizing interface (such as
Memory management interfaces) target memory is discharged, so, it can stop sending message, offloading the CPU.
