Abstract: IP packets encapsulation as link layer frames is necessary to a router design. In this paper we present an universal processor architecture for multi-channel packets encapsulation and forwarding, combined with FPGA embedded memory blocks, pipeline and multi-queue buffer mechanism, which improved the capability of short packets forwarding at wire-speed or burst flow transfer.
