Abstract: On basis of analyzing QoS function module and the structure of AMCC network processor, the network data plane software based on NP3450 is designed and implemented by using microcode and high-level programming language. Such mechanism as deep packet classification, the second look-up table, three scheduling and four groups of prospective entry-limit are introduced. The fine-grained QoS control based on stream is implemented. Experimental results show this design scheme is feasible.

Key words: network processor, data plane, packet classification
