document: Reaching strong consensus in a general network The strong consensus -LRB- SC -RRB- problem is a variant of the conventional distributed consensus problem -LRB- also known as the Byzantine agreement problem -RRB- . The SC problem requires that the agreed value among fault-free processors be one of the fault-free processor 's initial values . Originally , the problem was studied in a fully connected network with malicious faulty processors . In this paper , the SC problem is re-examined in a general network , in which the components -LRB- processors and communication links -RRB- may be subjected to different faulty types simultaneously -LRB- also called the hybrid fault model or mixed faulty types -RRB- and the network topology does not have to be fully connected . The proposed protocol can tolerate the maximum number of tolerable faulty components such that each fault-free processor obtains a common value for the SC problem in a general network
