Abstract: For congestion problems existed in the system of high-speed packet switching network,the paper analyzed existing traffic shaping technology for the congestion problems,proposed a multi-token bucket shaping algorithm supporting multiple queues.The algorithm implemented through VLSI design methodology.The operating frequency can reach 185 MHz with SMIC 0.13 μm standard CMOS cell library.Behavioral level simulation and synthesis results show that the algorithm can be simply implemented in hardware and can be effective for traffic shaping in packet-switched network.
