基于容错CORBA的可生存网络应用模型

Fault-tolerant CORBA-based application model for survivable networks

针对网络系统组件可能发生自然故障且多数安全机制都可能被攻击者破坏的问题,在分析网络可生存性的基本内涵以及可生存性研究与相关研究的联系的基础上,提出了一种基于容错CORBA的可生存网络系统设计模型,该模型采用对象主动复制的容错CORBA应用结合大数表决机制,可以检测和容忍恶意攻击和组件故障,并从其影响中恢复,从而保护了系统的可用性和完整性.

Aiming at the problem that component failure may occur naturally and most of the security mechanisms are likely to be deamaged in network system, the network survivability and the related security topics were overviewed. A fault-tolerant CORBA-based model was presented to design the survivable network applications. This model integrates object active copy in fault-tolerant CORBA （commonobject request broker architecture） and major voting to detect and tolerate malicious attacks and component failure, so that to resume system from their impacts and protect the availability and integrity for the network applications system.
