[jboss-jira] [JBoss JIRA] Updated: (JGRP-1021) Daisy chaining of messages

Bela Ban updated JGRP-1021:
---------------------------

        Summary: Daisy chaining of messages  (was: CLOUD_TCP: more scalable impl of TCP)
    Description: 
For non multicasting environments (e.g. clouds, which offer only TCP), sending message M to N members involves sending M  N-1 times. Rachid et al (see below) introduce a daisy chaining method, which has A send the message to B, B forwarding it to C, C to D and so on. This relieves A of some sending work and makes the line from A to the switch less contented. Throughput increases, although latency increases slightly, too.
