摘要：
A method for processing network traffic data includes receiving a packet, and determining whether the packet is a previously dropped packet that is being retransmitted. A method for processing network traffic content includes receiving a plurality of headers, the plurality of headers having respective first field values, and determining whether the first field values of the respective headers form a first prescribed pattern. A method for processing network traffic content includes receiving a plurality of packets, and determining an existence of a flooding attack without tracking each of the plurality of packets with a SYN bit.
