Title The Design and Implementation of LAN Multimedia Transmission System

Abstract Network communication is extremely important in everyday life。 People communicate through the network and data transmission。 In today's complex network conditions, whether it is for file transfer or exchange of information, it must be faced with insufficient network bandwidth or data loss during network transmission problems。 And in the local area network under conditions can make these effects can be minimized。

For network programming, through access and Consideration of relevant information, on LAN data transfer process and C / S software model, according to the characteristics of multimedia transmission, combined with Windows Socket network programming knowledge, completed the design of local area network multimedia transmission system with achieve。 To achieve a text transfer, file transfer and voice transmission capabilities。 Firstly, to design a simple task summary, and then introduces the design and realization of the related art network programming and development environment, as well as the entire local area network multimedia transmission systems, and finally introduces the difficulties I encountered in the system as well as the production and research system design experience。
