Performance measurement of DAQ-Middleware

Abstract

DAQ-Middleware is a software framework of network-distributed data acquisition system. DAQ-Middleware was developed based on Robot Technology Middleware (RT-Middleware), which is an international standard of Object Management Group (OMG) in Robotics. OpenRTM-aist is an implementation of RT-Middleware developed by the National Institute of Advanced Industrial Science and Technology. New implementation of DAQ-Middleware has been done according to the new OpenRTM-aist released early 2010 while DAQ-Middleware has been improved. Then, we measured the performance of the new DAQ-Middleware compared with previous one. We measured the throughput of DAQ-Middleware on several conditions. We observed improvement of performance in the new DAQ-Middleware.
