[jboss-jira] [JBoss JIRA] Resolved: (JGRP-1012) TP: fetch physical address associated with logical address more quickly

TP: fetch physical address associated with logical address more quickly ----------------------------------------------------------------------- Key: JGRP-1012 URL: https://jira.jboss.org/jira/browse/JGRP-1012 Project: JGroups Issue Type: Task Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.8 Currently, when we send a unicast message and don't have the physical address available, we send a discovery request for the physical address and trash the message. Later, when the physical address has been received and added to the transport's cache, the retransmission of the unicast message will succeed. In order not to generate too much traffic, we send such a discovery request only every 5 seconds (hard-coded) max. However, this is for *all* addresses. So if we have physical addresses for P, Q and R missing, the total time to send the 3 discovery requests will be 15 sec max ! So we would not be able to send a unicast to R for up to 15 secs ! This is bad, we should keep track of *which* addresses we've sent out discovery requests for, and have timeouts based on individual addresses, for example in the form of a cache (keys=addrs, values=last time sent).
