Examples of org.jgroups.stack.AckMcastSenderWindow

org.jgroups.stack.AckMcastSenderWindow
Keeps track of ACKs from receivers for each message. When a new message is sent, it is tagged with a sequence number and the receiver set (set of members to which the message is sent) and added to a hashtable (key = sequence number, val = message + receiver set). Each incoming ACK is noted and when all ACKs for a specific sequence number haven been received, the corresponding entry is removed from the hashtable. A retransmission thread periodically re-sends the message point-to-point to all receivers from which no ACKs have been received yet. A view change or suspect message causes the corresponding non-existing receivers to be removed from the hashtable.
This class may need flow control in order to avoid needless retransmissions because of timeouts. @author Bela Ban June 9 1999 @author John Georgiadis May 8 2001 @version $Revision: 1.10 $
