Abstract: According to the demand of high availability and real-time characteristics of real-time cluster system, and with regard to the effect of the network topology architecture of cluster system and the capability of network transmission on the system real-time performance, this paper gives a design and construction project of a redundant real-time cluster system with high availability, explains the design of systematic network topology architecture, estimates the data transmitting performance of network and discusses the realization of systematic parallel computing and the scheduling strategy of redundant group. The practical test proves that this system possesses the comparably high availability and real-time characteristics, and it can be used as the processing platform of periodical and high intensity multi-source floating-point information.
