Reliable multicast in Java

Question

What are the modern approaches to reliable multicasting in the Java world?

Searching the Internet, I came up with JGroups and JRMS. JGroups seem redundant in my situation (I want to have a set of identical nodes that interact together and allow them to join this group, notifying all existing nodes). JRMS looks like it's already dead.

I could not find any specific implementation of the PGM protocol for Java.

Answer 1

Check out jmdns that implements Zeroconf (Apple Bonjour) in pure Java.

It is very useful if you just want to find out who else is there and let them know about you.

Answer 2

Hazelcast says it supports messaging, among other things (distributed cards, etc.)

https://hazelcast.org/

It is used as a library in other distributed Java applications, such as OrientDB, Apache Camel, and has plugins for Java application servers, such as Tomcat session replication.
