JavaGroups - A Reliable Multicast Communication Toolkit for Java
NOTE: The latest version of JavaGroups is available at: (03)
http://www.sourceforge.net/projects/javagroups (04)
JavaGroups is a group communication toolkit written entirely in Java. It is
based on IP multicast, but extends it with
reliability and
group membership.
Reliability includes
lossless transmission of a message to all recipients (with retransmission of
missing messages)
fragmentation of large messages into smaller ones and reassembly at the
receiver's side
ordering of messages, e.g. messages m1 and m2 sent by P will be received by
all receivers in the same order, and not as m2, m1 (FIFO order)
atomicity: a message will be received by all receivers, or none.
Group Membership includes
Knowledge of who the members of a group are and
Notification when a new member joins, an existing member leaves, or an
existing member has crashed (05)
