[jboss-jira] [JBoss JIRA] (JGRP-1419) UNICAST / UNICAST2: combine retransmission for all members

Bela Ban created JGRP-1419: ------------------------------ Summary: UNICAST / UNICAST2: combine retransmission for all members Key: JGRP-1419 URL: https://issues.jboss.org/browse/JGRP-1419 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.1 UNICAST: - The sender has an AckSenderWindow, the receiver an AckReceiverWindow - The sender keeps retransmitting until the receiver delivers the message and acks it UNICAST2: - The sender has an AckSenderWindow (without retransmission) and the receiver a NakReceiverWindow - The receiver asks the sender for retransmission only if there's a gap - Stability ensures that the sender doesn't keep messages around forever Suggestions: - Similar to NAKACK, don't use a separate retransmitter for every member (window), but have just 1 retransmitter task scan the message tables and do retransmission - In UNICAST2, Table<Message> can replace the NakReceiverWindow on the receiver side - In UNICAST2, we can probably also replace the sender's window with a Table<Message> - in UNICAST, the sender's AckSenderWindow can also be replaced with a Table<Message> - In UNICAST, investigate whether the receiver window can be replaced with a Table<Message> as well ! If we can do this, then we have - only 1 proven data structure (Table<Message>) - not 1 retransmitter per window, but 1 for all the windows (saving space) ! -- This message is automatically generated by JIRA.
