FD
extends Protocol
implements Runnable
Passive failure detection protocol. It assumes a pbcast protocol, which uses rounds of gossiping for
reliable message delivery. Gossip protocols typically involve all the members sending gossips in regular
intervals. This protocol therefore works as follows: it allocates a timestamp for each member and updates
the timestamp whenever it receives a message from a sender P. Any type of message is accepted from P. For
example, PBCAST regularly sends the following messages:
- regular mcast message from P
- regular ucast message from P
- gossip from P
- retransmit request from P
- retransmit response from P
