摘要: 在大规模接入汇聚路由器(ACR)高速转发引擎的设计中,采用Xilinx公司Virtex-4系列FPGA的高速通道来满足高速转发引擎与交换网络接口输入/输出高带宽、高稳定性的需求。针对应用RocketI/O IP核时会出现的通道绑定不同步问题,该文提出一种RocketI/O通道辅助绑定的方案。实验结果证明了该方案的有效性。

Abstract: In design of large-scale access convergence router(hereafter referred to ACR) forwarding engine, the Xilinx Virtex-4 FPGA’s RocketI/O multi-gigabit transceiver is used to satisfy the need of high speed and steady interface between forwarding engine and switch fabric. This paper proposes an assistant channel bonding method for solving the difficult problem of channels-bonding synchronization. Experimental results show the method is effective.

Key words: RocketIO transceiver, channels-bonding, synchronization
