Design and Application of Multi-Queue FIFO in Core Routers
Junpeng Zhao · Telecommunication Engineering · 2005
Providing quality of service (QoS) is one of the most important researches on the Internet at present. The key issue of providing differentiated QoS is to schedule the priority queues in the core router. Based on analyzing the timing of QDR-SRAM, this paper focuses on the main ideas and approach of how to design the multi-queue FIFO by FPGA and QDR-SRAM. Subsequently this paper discusses the method of priority scheduling using the multi-queue FIFO in the core router. This design shows its easiness to be implemented in hardware and good performance in applications.
