Design And Research Of IP Multicast System On Multimedia Network Education

Along with the calculator technique, multi-media technical development of the technique, network, people explore to beg for various new mode which teach and learn in the network multimedia(terrace) to adapt the demand of education reform.The familiar network multi-media teaching system (terrace) exists not a few problems, among them main problem is lack to sow efficiently and much with solid hour broadcast of function, and put together these function and various knot with organic teaching mode. For resolving these problems, the our thorough analysis studied a multi-media technique, IP set to sow a technique, we discover flowing medium delivers a technique in of sow technique more can let when the medium server carries to send out a continuous data to flow but don't produces to postpone toward several customers in the meantime, but again will not produce broadcast storm, raise network utilization biggest.This thesis is exactly the application which aims at this, setting up 1 to sow much according to the Ip of network medium teaching application project. This thesis emphasized to study to sow agreement more and sow road more from, flow medium to adjust one degree technique and save a technique and obstruct a control technique slowly, put forward multi-media network teaching IP to sow much of total project, and from sow server more to carry with the customer carry, screen broadcast etc. the main aspect elaborate on its research, design of all processes. That project has already got a first step application currently, also needing a further experiment and the improvement.Chapter 1:elaborate the research background, topic source of topic;Chapter 2:elaborate the education theories, multi-media technique that the topic realization involves and flow medium technique etc;Chapter 3: The multi-media network teaching sows total project more.Elaborate system to constitute, the system design thought, each main interface design and function brief introduction;Chapter 4: The realization of the network multi-media parts of functions of the teaching system.Mainly discuss correspondence mold piece and screen to broadcast system of concrete realization;Chapter 5: This system carries on summary, putting forward some conceive.
