Abstract: The technologies of information diffusion and compression for network based computer conference are equally important to improve the performance of the whole conference system.Here introduced are some novel diffusion approaches based on distributed processing under the local and wide area network environments.And these approaches have the magnitude improvement over the conventional full linear concentrated diffusion ones on diffusion span time.Different diffusion scenarios are detailed and the related analysis using diffusion balance tree is also given.Some applications of these approaches under different network environments are illustrated.
