Revisiting Fault Diagnosis Agreement in a New TerritoryFault Diagnosis Agreement • September 21st, 2010
In convention, to consensus has been discussed variously. The way of fault masking is commonly used to reach consensus. But, reaching consensus is not enough in a high reliability application. Therefore, in this study, the fault diagnosis agreement is visited. The proposed protocol does not only reach an agreement for healthy processors but also detect and locate the faulty components in a synchronous unreliable network. We also enlarge the fault tolerance capability by allowing both dormant faults and malicious faults exist in a network. That is, the proposed protocol can tolerate, detect and locate the maximum number of faulty components with the dual failure mode to solve the consensus problem and fault diagnosis agreement problem in a synchronous distributed environment by minimum number of rounds of message exchange.
Reaching Fault Diagnosis Agreement on an Unreliable General NetworkFault Diagnosis Agreement • September 9th, 2010
Recently, Siu, Chin and Yang failed in their attempt to use the FDAMIX protocol to eliminate the Fault Diagnosis Agreement (FDA) problem with mixed faults on the processors in a general network. Therefore, in this study, a new protocol, the FDAL protocol, is introduced to solve the FDA problem with mixed faults on the links. The FDAL is capable of detecting/locating faulty links to reconfigure the unreliable general network into a reliable network, and is able to increase the system performance and strengthen network integrity.
