Approaches to implementation of a repairable distributed recovery block scheme
K.H. Kim, Jaesung Yoon · 2003
The authors previously proposed (1984) the basic concept of the distributed recovery block (DRB) scheme as an approach to uniform treatment of hardware and software faults in real-time applications. Design issues that arise in implementing the DRB scheme are discussed together with some promising approaches. Issues in extending the DRB scheme with the capability of reincorporating a repaired node without disrupting the real-time computing service are also discussed. An experimental implementation of the repairable DRB scheme into a real-time distributed computer system (DCS) testbed and subsequent measurement of the system performance demonstrated the fast forward recovery capability and the logical soundness of the scheme.>
