Design And Implementation Of Media Distribution System In Interactive Online Classroom

With the high-speed development of Internet, online teaching has become a new hot area. It's useful to design an online teaching system simulate the Real teaching scenes. Because there is a lot of network data transmission in the course of network teaching. So, it's very important to solve the problem of how to send interactive data form teacher to the students, in the condition of terminal resources are limited, bandwidth is certainly.In order to transmit data efficiently in the course of network teaching and provide good teaching interaction experience. In this thesis, design and implement a teaching oriented media distribution system, based on the architecture of distributed transmission of data and P2 P. The date in interactive teaching classroom is divided into control data and media data. Control data is adopted in star model to exchange data. For media data, designed a tree model to help distribute data. The whole system adopts modular design, divided the system into the user interface module, data analysis module, the data distribution module, system interface module. In the system, design the network management module, data buffer, and resource management to implement the data distribution of transmission structure.At last, the function and performance of this system are tested. To verify the basic teaching control command execution, the maintenance of network topology and the correctness of the data transmission. Comparative analysis using distribution transmission media data and the traditional C/S architecture transmission nodes for teachers or students of system resources occupied test etc. Tests revealed, this system can carry basic network teaching tasks, and less affected by computer performance and network bandwidth. Achieve the function of the design and performance requirements.
