· Logical addresses prevent reincarnation issues: when a member address is IP:port and the port is fixed, then - when
· a member is restarted - it will get the same IP address and port. Therefore, for JGroups it is the *same* member !
· Since a member's address is associated with state (e.g. retransmission tables and seqnos) in various protocols, some

· lead to no messages being processed for a reincarnated member, or all messages being queued.

· A logical name is a name that's given a channel and stays with the channel until the channel is closed. This leads to
· much more readable output, e.g. we can replace view {192.168.1.5:56789|2: 192.168.1.5:56789, 192.168.2.30:4666} with
· {A|2: A, B}. This is very useful for example when reading logs.
