In order to meet the heterogeneous requirements from service providers and users simultaneously, there is an urgent need for a new information service system. After studying the characteristics of the users? accessing, that popularity of information utilization generally exists in information system is focused. This paper introduces a rating oriented distributed information system sustained by push/pull mobile agents for information service provision and utilization. Based on this environment, autonomous information allocation technology is proposed. However, when users? demand changes, congestion might arise in the system. In order to achieve load balance for users? timeliness access and guarantee that users can always get the information from a certain pathway, autonomous information reallocation technology is proposed. Through the comparison simulation to the conventional system, the effectiveness of proposed system is proved.
