With the evolution of the Internet, current routers need to support a variety of emerging network applications while the high packet processing rate is still guaranteed. As a result, the network processor has become a promising solution for network devices due to its computation capability and programming flexibility. However, developing the network applications on network processors is not easy. How to efficiently program multiple processing elements and utilize various memory modules as well as the hardware resources on network processors are always challenges. In this paper, the authors investigate several optimization issues and programming techniques that should be considered by the developers to achieve higher packet processing rate on network processors.
