Evaluation of Gigabit Ethernet with Java/HORB

We have evaluated a high speed network, Gigabit Ethernet(GbE), with Java/HORB, which means Java and Java-based Distributed Object Technology(DOT). Next generation of data acquisition(DAQ) needs high speed network such as ATM and GbE for data transfer in Level 3 and/or Level 2 trigger of the DAQ at large scale DAQ system like Large Hadron Collider(LHC). When evaluating the basic parameters of GbE, we considered bottleneck of network performance such as TCP buffer size, memory access speed, Maximum Transmission Unit(MTU) and so on. We used network tools called TTCP and Netperf and some Java benchmark programs for evaluating DOTs, namely, HORB, RMI and Voyager.
