Multi-agent system and OSGi technologies are essential elements in realizing the upcoming ubiquitous environments. Up until now, different approaches are proposed to support the reliability of multi-agent system level by many researchers. Also, there are mainly focus on fault-tolerance of detection/recovery in the inside system fault or each agent level. We have view on them; will be provide an effective solution of service level for supporting the service reliability of an extended Directory Facilitator (DF) in multi-OSGi agent system. We propose a new, more reliable and extendable DF architecture, and present a detection/recovery algorithm of service fault for safety in railroad system. Through the proposed fault-tolerance architecture, the extended DF of multi-OSGi agent system can improve reliability and interoperability of the service level.
