Wait delay is lacked.
In one embodiment of the application, before the first CPU forwards fragment message, the burst report can be first determined
Whether text is first fragment message corresponding to raw data packets.If first fragment message, then the first CPU turns the fragment message
Send out；If not first fragment message, then the first CPU determines whether the first CPU is upper one corresponding to forwarding raw data packets
The CPU of individual fragment message；If the first CPU, then the first CPU forwards fragment message；If not the first CPU, then wait
For a period of time.
It is not a upper fragment message corresponding to forwarding raw data packets that if the first CPU is also to determine after a period of time
CPU, then it is considered that there is packet loss phenomenon, the first CPU deletes fragment message corresponding to the raw data packets of forwarding,
Forwarding, the fragment message is meaningless, the fragment message can be abandoned, to save Internet resources.If is determined after a period of time
One CPU is the CPU for forwarding a upper fragment message corresponding to raw data packets, then the first CPU forwards fragment message.
In the embodiment of the present application, for example, CPU0 is by after a fragment message 01 forwards corresponding to raw data packets 01,
Record current slice number and the next burst number that the fragment message 01 includes；As the CPU0, to get raw data packets 01 right
, can if the current slice number that the fragment message 02 includes is identical with the next burst number recorded during the fragment message 02 answered
To determine CPUs of the CPU0 as the upper fragment message corresponding to forwarding raw data packets 01；If the fragment message 02 includes
Current slice number and all next bursts number for having recorded it is different, then it is not to forward raw data packets that can determine the CPU0
The CPU of a upper fragment message corresponding to 01.

CPU is identified.
If step 204, CPU1 do not find CPU corresponding to check value 1 and identified in step 203, and determine burst report
Text 1 is first fragment message corresponding to raw data packets 1, then records the corresponding relation of check value 1 and CPU1 mark.
Step 205, CPU1 forward fragment message 1.
If step 206, CPU1 do not find CPU corresponding to check value 1 and identified in step 203, and determine burst report
Text 1 is not first fragment message corresponding to raw data packets 1, then abandons fragment message 1.
In one embodiment of the application, CPU1 can also wait for a period of time, if not finding school after a period of time
Test CPU corresponding to value 1 to identify, CPU1 abandons fragment message 1.
If step 207, CPU1 find CPU marks 01 corresponding to check value 1 in step 203, it is determined that being identified as CPU marks
Know 01 CPU.
If step 208, CPU1 determine CPU in step 207, mark 01 is identical with CPU1 mark, and determines burst report
Text 1 is first fragment message corresponding to raw data packets 1, and fragment message 1 is forwarded.
If step 209, CPU1 determine CPU in step 207, mark 01 is identical with CPU1 mark, and determines burst report
Text 1 is not first fragment message corresponding to raw data packets 1, determines whether CPU1 is upper one corresponding to forwarding raw data packets 1
The CPU of individual fragment message.
If step 210, CPU1 determine that CPU1 is a upper burst report corresponding to forwarding raw data packets 1 in step 209
The CPU of text, then forward fragment message 1.
If step 211, CPU1 determine that CPU1 is not a upper burst corresponding to forwarding raw data packets 1 in step 209
