Modern networks require the flexibility to support new protocols and network services without changes in the underlying hardware. Routers with general-purpose processors can perform data path packet processing using software that is dynamically distributed. However, custom processing of packets at link speeds requires immense computational power. This paper proposes a design of a scalable, high-performance active router. Multiple network processors with cache and memory on a single application

... pecific integrated circuit are used to overcome the limitations of traditional single processor systems. The proposed design is used as a vehicle for studying the key issues that must be resolved to allow active networking to become a mainstream technology. Benchmark measurements are used to put the design in relation to actual application demands. Index Terms-Active networks, multiprocessor system-on-achip, programmable network benchmark, router design.
