Fundamental architectural considerations for network processors

Network processors (NPs) are programmable devices with special architectural features that are optimized to perform packet-processing functions. They have emerged to cope with the ever-changing networking applications that are becoming increasingly complex. NPs are expected to become the silicon core of network equipments that require a high degree of flexibility to support evolving network ser...
