Research On The Relevant Technology Of Network Distributed Computing Using Java

Most distributed computing systems were developed by C/C++. It has more work efficiency, but there are many shortcomings on migrate ability, maintenance and security. In this paper, Java was applied in developing Distributed Computing System. The goal is to reduce software development cost, improve migrate ability through Java's feature of crossing platform, make the participant's computer system avoid the hostile attack by Java's security model and decrease the possibility of Distributed Computing System being repeated developed.In this paper, Java multithread technology was used in detecting and using client idle CPU cycles. Java security model was used in ensuring client security. Dynamic load balancing was realized by job pool with JDBC technology. The communication between client and server was implemented by RMI. Finally, a simple distributed computing prototype was made. Its character was that not only data but also executable programs could be transferred between Client and Server. This model validated the feasibility of above works.
