%X Streaming media service is getting to be a typical application among today's network services. In order to im- prove the availability of the streaming media service and guarantee the quality of service, it is important but difficult to make the stream hand-off quick and efficient. This paper simply introduces the key problems which the hand-off of streaming media service is facing and the advantage of the grid technology to implement the hand-off of streaming media service. Combining RTSP sessions and the monitoring technology on streaming media transmission, it implements a hand-off system of the streaming media service in the Globus-based streaming media service grid NDSSG, which can support the hand-off that occurs when the server breaks down or load-balancing happens. It proves by the practice in NDSSG that applying the advanced grid technology can implement highly efficient hand-off of the streaming media serv- ice, can effectively improve the performance and quality of the streaming media service.
