Abstract： At present,the backbone network transmission rate continues to increase,and the demands for highspeed network signal processing system are quite urgent.The backbone network has brought many difficulties to the entire network space management due to its highspeed and large bandwidth features.This paper takes the network flow defined by fivetuple as the research object,and through the theoretical analysis,shows the design and implementation of the hardware platform of highspeed network flow recognition and processing system.This system can achieve the recognition of network content in flowlevel.And according to the result of recognition,different strategies are employed in order to achieve network flow classification.
Key words : high-speed signal;network flow;flow recognition
