Abstract:

Data dissemination is a novel active service architecture based on the IP multicasting or IP broadcasting technology. It can be widely applied in LAN,WAN and digital broadcasting network,and transmits the hot-information to massive consumers. The services and transmission characteristic of data dissemination was concluded,re-transmission ratio and computing methods which can improve the errors of communication channels was submited.The sending and receiving algorithms and implementation codes for data dissemination were discussed.

Key words: data dissemination, software design, resource schedule, reliable data transmission
