Content-centric networking (CCN) is one of new proposed architectures for future Internet technologies. Data or content distribution can be accessed in a name-centric fashion in CCN. In this paper, and we evaluated the CCN file transmission procedure under a real circumstance called Open Network Laboratory (ONL) where each machine is to be loaded with a popular open source CCNx software. And based on the design of two file transmission examples within one network topology configuration, we can test the file download performance in CCN.
