Using the technology of remote control, The remote computer as conveniently can be controlled as the local one .The technology of remote control can be very useful in the maintenance , monitoring and malfunction diagnosis of remote computers. However , the current software of remote control offers only a fix ed transfer speed .The modes o f linking to Internet are diverse and the link speed is different greatly .Furthermore , link speed of user is possible to vary with line quality and network jam .Thus , the fixed transfer speed limits the use of the software .The software with dynamic transfer speed was implemented through adjusting dynamically compression ratio of the screen images.The principle of remote control software w as introduced .The program design method and outline to realize remote control with dynamic transfer speed by using Java w ere descried in details.Also , the concrete method of implementation was given.
