In aerospace, the design principles have transformed from the pursuit of performance to a balance among performance, costs, reliability and other aspects, and how to meet the system performance requirements under the premise of minimizing costs has become a serious problem. In this paper, the relationships between the constellation availability and the satellite reliability were modeled considering the replacement mode of the back-up satellite. A case study was presented to show the effects of the satellite reliability on constellation availability.

E-mail security scanning software is being widely used. With the rapid increase of user number and system flow,there are insurmountable problems in terms of performance,robustness,maintainability and scalability in the traditional tightly-coupled and synchronous IMHS(Inter-scan Message Hosted Security) system. With regards to the system bottleneck by the mass users,a loosely-coupled,asynchronous,stateless principle was proposed for system design. Through the integration of cloud computing and Service Oriented Architecture(SOA) technique,a P2P-based E-mail secure cloud service system was designed and implemented. The system supports dynamic collaborative process,and effectively improves the efficiency of resource use and system scalability. The results and analysis of typical operation tests in real system verify the feasibility and effectiveness of the system architecture.
