摘要：Persistent Computing Systems (PCSs) were proposed as a new generation of reactive systems to provide reliable and secure computing services continuously and persistently to their users anytime and anywhere during running, maintenance, upgrade, reconfiguration and even during various attacks. Soft System Bus Based systems (SSB-based System) were proposed to implement PCSs to be built by connecting components of the system using the SSB and can provide continuous functioning and dynamic adaptability that are the two most fundamental features of PCSs. Though an implementation method of SSB-based systems exists for distributed systems, there was none for centralized systems. This paper proposes an implementation method of SSB- based systems for centralized persistent computing systems (SSB-based CPCSs). that satisfies the two fundamental features. The paper gave an analysis of various events which obstruct continuous functioning of a system at first, and then presented requirements for and a design of SSB-based CPCS. The paper also presented our experimental results to measure the rate of continuous functioning, correctness and time delay and showed that the components can provide high continuous functioning with correct output where delays vary for each event.
