摘　　要：使用IPMulticast\JMF技术设计一个多媒体网络会议系统,可对网络会议中常用的文件任何格式的图片、视频、音频等数据进行有效可靠的传输并且传输到客户端进行实时显示。采用IPMulticast技术作为数据传输的方式,可以使有限带宽负载最大的信息量,节省有限的网络资源。用JMF技术和RTP/RTCP协议相结合可以实时传播多媒体数据流和自适应网络带宽,进行有效地控制多媒体流。实现多播的对等设计。In this paper,we design and realize a multimedia net meeting system with IPMulticast and JMF technical. It commonly uses on the net meeting documents (text documents, word documents, pdf documents …), any form of pictures, video, audio, and other data for effective and reliable transmission and real-time show. IPMulticast technology as a means of data transmission can load the largest amount of data with limited bandwidth , save limited network resources. RTP/RTCP agreement with JMF technology can real-time transmit multimedia data flow and real-time adapt network bandwidth for effective control of multimedia streams. This software ‘s major innovation is the design of symmetry IPMulticast.
