| 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. |
