摘要: The component-based system will provide a predefined survivability specification which consists of corresponding degraded services in the presence various kinds malicious attacks, failures or accidents. main contributions this paper are (1) presenting method to represent service core based on component families and installation orders, can precisely capture perceived by users; (2) proposing reasoning rules recovery compatibility execution, used judge success property (the newly started works well) safety (formerly not damaged); (3) algorithms simplify execution concept projection, supports analysis big scale. By process specification, be systemically applied practice. A named MVoD (mobile video-on-demand) is illustrated demonstrate practicability efficiency formal model method.
