ATCA架构中多网口后板的高效设计

摘要

介绍了多网口后板(RTM)的普通设计方案,提出了优化解决方案,并从软、硬件方面进行了比较,并且描述了新方案在卸载CPU负荷、防止“中断风暴”等方面的创新性设计.%The paper first introduces normal design of RTM boards with multiple ports, and then the optimized new design is presented. Through comparing them on the aspects of software and hardware, it finally describes some innovatory ideas of the new design, including CPU offloading, "interrupt flooding" preventing and so on.
