摘要：

DAQ-Middleware is a software framework of a network-distributed data acquisition system for a small or middle size experiment. The middleware is based on the object-oriented technology and a CORBA technology for the communication. We can develop a small DAQ system easily by using the DAQ-Middleware. But communication performance of the system wasn't good in comparison with normal socket communication. One of the reasons might be a communication mechanism. Then we proposed two communication mechanisms to improve its performance. One is a direct communication method in a user space, and the other is a simple object communication method in a framework space. We measured throughput of data transfer between two components as their communication performances for these new mechanisms. The result of the proposed direct communication method is about 2.4 times faster on the average than the present system and the result of the proposed simple object communication method is about 1.5 times faster on the average. As a result, the performances of both mechanisms were improved.
