Space information networks promise encouraging prospects in areas of detection, communication and location. In this paper, node and link evaluation algorithms are proposed to provide reconfiguration basis for such networks. Given that space information networks operate in multi-application environments and offer diverse services, we take connectivity and availability into comprehensive consideration. The method of analytic hierarchy process and node isolating are used in link and node importance evaluation respectively in order to generate service oriented evaluation results. Simulation results by NS2 demonstrate that the proposed algorithm reflects facts more objectively, which can help reconfiguration measures adaptively adjust their action scope in order to reduce reconfiguration overhead.
