[0130] Example
[0131] An embodiment of the present invention is given below to illustrate the process of data packet filtering in the present invention. The specific data packet filtering steps are as follows:
[0132] Step 1: The mPIPE unit of the Tilera multi-core accelerator card mounted on the universal host obtains the data packet PA sent from the network device in , MPIPE gives PA to all received packets in According to data packet PA in The order of arrival plus a timestamp, the data packet at this time is
[0133] PA={packet 1 ,packet 2 ,packet 3 ,packet 4 ,packet 5 ,packet 6 ,...,Packet M }.
[0134] Read all data packets from mPIPE unit
[0135] PA={packet 1 ,packet 2 ,packet 3 ,packet 4 ,packet 5 ,packet 6 ,...,Packet M } And put all the packets
[0136] PA={packet 1 ,packet 2 ,packet 3 ,packet 4 ,packet 5 ,packet 6 ,...,Packet M } Stored in the buffer.
[0137] Step two, for all the above data packets
[0138] PA={packet 1 ,packet 2 ,packet 3 ,packet 4 ,packet 5 ,packet...
