Internet traffic management based on AMCC network processor

The remarkable and continuous increase in link speed and application variety of Internet calls for new QoS provision technology that is both efficient and flexible. Being a kind of application-specific processor optimized for network computation, network processor (NP) combines the high performance of hardware and the flexibility of software, which exactly meets the demands of nowadays Internet traffic management and QoS provision. This paper originally presents an efficient traffic management mechanism based on AMCC network processor. The data-plane software architecture, the manipulation process, especially some key components such as accurate traffic classification, flexible access control and three-step scheduling are discussed in detail. We implement the traffic management mechanism based on NP3450 network processor and test it using Spirent AX/4000 broadband test system. The test results show that our proposal can efficiently provide QoS guarantee for various traffic category on OC-48 links.
