| Abstract: | Depending on the high packets-forwording effiecncy of special ASIC processors and flexbile programmability of general RSIC processors,network processor becomes core technology for driving the development of next generation network.In this paper,the character of packet classifier and scheduler is introduced.On the basis of analyzing NP3 framework,the hierarchical scheduling and deep packet process are adopted based on multi-domain.the design of DiffServ application by using NP3 is discussed.Test results indicate that this scheme is reasonable and feasible. |
