Abstract: Due to the diversity of internet applications and services, traditional software-based networking devices may not be sufficient to afford the processing load imposed by the services. One example is the mixed-version IP environment in which routers must handle the IPv4/IPv6 translation while keeping the IP processing at the line speed. In this paper, we present our work for the design of a protocol optimised packet processing engine that provides common IP services and mixed-version translations. This silicon is written in VHDL and is tested in a Xilinx Vertex II FPGA development board.
Keywords: system-on-chip; IPv6; packet engine; embedded systems; NAT-PT; routers.
