基于10Gbit/s传输的光纤旁路系统平台研究与设计

摘要

This paper designed a kind of ifber bypass instructment based on 10 Gbit/s transport system, which protects the node devices of backbone network, we focus on the key issues during the u-boot transplantation process base on MPC8308ERDB . With the u-boot provids the most abundant supports for the PowerPC processors, and combined with the BSP source codes, analysed the compliation and conifguration process of the u-boot,and ifnally emphatically analyzed the transplantation of the u-boot.%本文基于MPC8308ERDB设计了一款基于10Gbit/s传输的光纤旁路保护器，用于保护接入骨干网的节点设备，重点分析了针对MPC8308ERDB开发板的u-boot移植过程中的关键问题。凭借U-boot对PowerPC系列处理器最为丰富的支持，结合飞思卡尔提供的BSP源代码包，详细地分析了u-boot源代码的编译及配置过程，重点分析了u-boot的移植过程。
