[jboss-jira] [JBoss JIRA] Commented: (JGRP-615) UDP: JGroups always allocates the same ports

[ http://jira.jboss.com/jira/browse/JGRP-615?page=comments#action_12385552 ] Bela Ban commented on JGRP-615: ------------------------------- I chose not to implement the kludge described below. This is overhead, especially on operating systems where it is not used. According to http://tools.ietf.org/html/draft-larsen-tsvwg-port-randomization-02 (section 2.2), the algorithm for port allocation is: next_ephemeral_port = 1024; /*initialization, could be random */ /* Ephemeral port selection */ count = max_ephemeral - min_ephemeral + 1; do { port = next_ephemeral; if (next_ephemeral == max_ephemeral) { next_ephemeral = min_ephemeral; } else { next_ephemeral++; } if (four-tuple is unique) return port; } while (count > 0); return ERROR; This should actually always allocate the next available port ! Need to investigate why this is not the case... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
