Failure Detection and Recovery Mechanisms

Mechanism
Description
Chained Failure Detection
"afpchain" Detects crash failures by missing hearbeats. Cost of heartbeat generation and validation are amortized using the chained failure detection mechanism (see publication page)
ConfigMeaning/Value
hash Hash function used to ensure key distribution message integrity (enum, values "md5")
maxdrophb number of consecutive lost heartbeats lost before declaring a process failed (integer, > 0)
hbperiod period between sended/expecting heartbeats (integer, > 0)
chainlen Length of hash chain. Note that the length of the chain has an affect on performance. Consult the chained failure detection algorithm paper (integer > 0)
