[jboss-jira] [JBoss JIRA] Commented: (JGRP-701) Investigate making FD_ALL the default failure detection protocol

Investigate making FD_ALL the default failure detection protocol ---------------------------------------------------------------- Key: JGRP-701 URL: http://jira.jboss.com/jira/browse/JGRP-701 Project: JGroups Issue Type: Task Reporter: Bela Ban Assigned To: Bela Ban Priority: Minor Fix For: 2.7 Replacing FD, so the new combo would be FD_SOCK and FD_ALL. The advantage of FD_ALL is that we detect *many* concurrent failures much faster than FD. E.g if we have A,B,C,D,E and B and C fail, and FD.timeout=1000 and FD.max_tries=3, FD_ALL.timeout=3000 and FD_ALL.interval=1000, then: FD will take timeout * max_tries ms to detect the death of B and the same for C, so a total of 6 seconds. FD_ALL will take timeout ms to detect both failures, so a total of 3 seconds. FD_ALL is also much simpler in its implementation, therefore simpler to verify for correctness
