Abstract


Multimedia distance education is the teaching mode based on computer and network, so that we can accomplish the tasks of teaching in different places or at different times. The distributed multimedia distance education system is low cost, and it can effectively overcome the limitations of time and space, and is being morewidely used. Multimedia distance education system needs to solve the key problem of how to transfer the audio and video to the destination by internet technology effectively. The multimedia distance education system needs to transmit audio and video in real time, so the transmission delay must be reduced in order to ensure the teaching and interaction between teachers and students. In this paper, we design a more advanced and efficient remote teaching system based on the node management of a distributed system. Firstly, we take the distributed multimedia technology as the key technology and an important means to facilitate the transmission of streaming media data. Then, we put forward the method of configuration management and state management in the media server cluster. Secondly, on the basis of the previous method, we put forward a method of load balancing management based on RTCP control message. Based on the design in this paper, we realize the orderly and efficient management of the media server cluster in a distributed system. Finally, we simulate the performance test of the node management in the media server cluster to validate the advantages of the node management. This design can effectively reduce the transmission delay of streaming media data.
