what best methods/algorithms available select leading node in cluster of nodes, knowing nodes come , down @ anytime? if implementations available in java, plus.
i've implemented paxos algorith before in java. it's useful, , simple. (it took 16 hours put demo of it, using threads simulate servers. worse @ threading then!)
it won't select leader exactly... allow various nodes agree on leader. have leader selection algorithm, because each node going pick it's own node lead, may find "civil war" among nodes. paxos algorithm allows picked leader real leader.
