Performance measurements of mixed data acquisition and LAN traffic on a credit-based flow-controlled ATM network

The high speed network is a key component in networked data acquisition systems. An ATM switch is a candidate for the network system in a DAQ (data acquisition system). We have studied the DAQ performance of the ATM network at the RCNP (Research Center for Nuclear Physics) at Osaka University. Data traffic on DAQ system has a very different traffic pattern from other network traffic. It may slow down the network performance. We have studied the network performance for several traffic patterns.
