Remote Procedure Call Scheme to Support Fault-Tolerance
Han Jin, Koo Yong Wan · The Transactions of the Korea Information Processing Society · 1995
RPC(Remote Procedure Call) has been studied for programmer to easily write distributed program of little bit higher efficiency and reliability. In this study, fault-tolerant remote procedure call for hardware failures is proposed. Fault-tolerance is supplied by replicated procedures with node group, so called chain, and copies along chains are linearly ordered. Calls for procedure are sent to primary copy along chains, and other copies are propagated internally. If failures happen, first copy in faultless chain returns the result to the caller, Especially, in this study processing of redundant call message and result message, while using limited ack message, are avoided. This method supplies efficient and reliable fault-tolerance compared with existing remote procedure call.
