[jboss-jira] [JBoss JIRA] (JGRP-1396) Merge NakreceiverWindow and Retransmitter

[Bela Ban (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1396?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12647521#comment-12647521 ] 

Bela Ban commented on JGRP-1396:
--------------------------------

We could now not have retransmission timeouts per seqno or seqno range, but for the entire bitmap. Perhaps we can decrease the interval when we have many missing messages, and increase it when we only have a few ?
Or we could partition the bitmap into N parts: the first parts are sent more frequently the the last parts, as the elements of the bitmap are in order of reception: older messages are towards the head, more recent messages towards the tail of the bitmap...

> Both NakReceiverWindow and Retransmitter use their own data structures to keep a list of messages received (NRW) and seqnos to be retransmitted (Retrasmitter). This is redundant and costly memory-wise.
> I suggest let's merge the 2 classes, or at least let them share the data structure which keeps track of received messages.
> Suggestion II: create a ring buffer with a (changeable) capacity that keeps track of received messages and messages to be retransmitted.
