A layered approach and modular design, with open APIs,
hides the unnecessary details of experiment operation and
complexity from users. In addition to the testbed software
packages and libraries, it is expected that re-usable components
and packages will also be developed by the user community. In
order to support user experiments, the ORBIT testbed has a
software framework as shown in Fig.4 consisting of
management/control software as well as user level application
software for the radio nodes.
