Abstract: Multimedia business network architecture is to raise the transmission rate of multimedia information, reduce the delay characteristics of the transmission process, so the multimedia service website can operate fast, reliable. In this paper we use multiple distributed IP technology to design the multimedia business network structure of IPV6. In order to verify the performance of network structure, we use IPerf software to test the performance of IPV6 multimedia business web site, and compare the performance of network under different distributed IP. By contrast, the network transmission speed of the multi distributed IPV6 is highest, delay characteristics are the shortest; and the distributed IPV6 is secondary; the worst is the general distributed IP. The transmission rate is 2.32 M/s; network delay characteristics can reach 232.21 ms, which verifies the important role of distributed IP in the multimedia business site structure. It provides technical support for the study of multimedia network.
