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/interworking between devices in multi-domain/multi-layer heterogeneous optical networks and path computations.In consideration of the requirements of PCE development and the characteristics of embedded systems

a board support package is preloaded 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.
