介绍一个基于嵌入式 Linux的PCE(路径计算单元)硬件系统设计及实现实例，其主要目的是用于光网络中“PCE+网管”架构的测试，也可用于多域多层异构光网络设备间的互联互通及路径计算。考虑到 PCE开发需求及嵌入式系统的特点，为硬件系统的使用者预先载入板级支持包，完成硬件的启动引导。文中首先根据该 PCE 架构的需求比较了主流嵌入式Linux操作系统的异同及优缺点，然后就硬件系统的设计、实现和初始化做了详细的阐述，最后给出了一个可以成功运行的PCE测试实例及部分实验成果。

The paper will introduce a design and implementation of the PCE hardware based on embedded Linux system.This system is chiefly used in the tests of PCE+network management architecture in optical networks and in the interconnection/in-terworking between devices in multi-domain/multi-layer heterogeneous optical networks and path computations.In considera-tion of the requirements of PCE development and the characteristics of embedded systems,a board support package is preload-ed for the system users to boot the hardware.Furthermore,in this paper,the similarities and differences and advantages and disadvantages are compared against the requirements of the PCE architecture and then the design,implementation and initiation are described in detail and an operable PCE test case and parts of the experimental results are given.
