In row, otherwise, into queue corresponding with non-fragment message；When an interrupt occurs, DGE1 processors to corresponding queue into
Row goes out team's application, and sends the data to CPU, so that CPU carries out subsequent processing；
When data packet comes from the outer network interface of Ethernet：DGE2 processors configure the data packet to receiving according to itself
Carry out the dissection process that layer 2 arrives layer 5；After dissection process is completed, the request that application is joined the team, BQM processing are sent to BQM processors
It after device receives request, checks whether data packet is fragment message, if it is fragment message, then enters team corresponding with fragment message
In row, otherwise, into queue corresponding with non-fragment message；When an interrupt occurs, DGE2 processors to corresponding queue into
Row goes out team's application, and sends the data to CPU, so that CPU carries out subsequent processing；
When data packet comes from CPU：According to business demand, CPU applications enter the queue of SEC processors, at this point, starting
After SEC processors receive task, encryption and decryption or integrity protection are carried out according to itself configuration to data packet for SEC processors
Or the processing of completeness check；After processing is completed, the request joined the team of application is sent to BQM processors, BQM processors according to
Preconfigured queue decisional table carries out judgement of joining the team, for example, if message characteristic is 0x8c00, enters the corresponding teams of CPU
In row；If message characteristic is 0xc400, enter in the corresponding queues of CPU；If message characteristic is 0xd000, enter
In the corresponding queues of CPU；If message characteristic is 0xd400, enter in the corresponding queues of CPU；CPU according to own situation, from
Data are read in corresponding queue, so as to the subsequent processing of CPU.
