At present, existing System Wide Information Management (SWIM) has dramatically changed the information architecture of point-to-point data exchange ones while little attention is placed on the efficiency of information exchange. This paper gives a proposition on the efficient information exchange method compatible with SWIM on the basis of UDP multicast. Theoretical analysis and simulation prove that reasonable packet size can take a strict control on the packet loss rate within an acceptable range. Additionally, comparison with the existing SWIM system presents that it also can lower down latency and server load ratio, especially at the time of the large number of users. It is worth to mention that this method has obvious advantages in transmitting including radar data, in terms of the features and requirements of different data.
