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

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...
Merge NakreceiverWindow and Retransmitter
-----------------------------------------
Key: JGRP-1396
URL: https://issues.jboss.org/browse/JGRP-1396
Project: JGroups
Issue Type: Enhancement
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.2
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.
