The Study And Implementation Of Distributed Object Load_balancing Based On Java RMI

With the development of distributed object technology, it's an important research direction to provide load_balancing scheme for server cluster on object level. To cluster remote object servers which are built based on Java RMI distributed object technology, the author presents an distributed object load_balancing model RMI-DOLB after analyzing the characteristics of Java RMI, and completes the RMI-DOLB system. In this paper, a load_balancing service provider is developed upon JNDI SPI to provide a Java2-compatible uniform entry to RMI-DOLB system for client. The extention of remote object adopts RMI activatable object to void unreasonable occupy of system resource. RMI load_balancing server provides load_balancing service as well as object-level and host-level management. RMI-DOLB uses RMI as communication protocol between every parts. At last, through applying RMI-DOLB on Java Chinese platform, one practice of RMI-DOLB is shown.
