Multicast is the default communications mode used in Rhino.
This mode allows for automated cluster membership discovery by using the properties of multicast behaviour. When the network supports multicast this is the preferred communication mode, as it is much easier to configure in Rhino.
Nodes communicate by sending messages to well-known multicast groups. These are received by all nodes within the same network.
Configuring multicast
Configuration of multicast is very simple.
A multicast address range must be specified; addresses from this range are used for different internal groups.
Configuring this is handled by the rhino-install.sh
script.
Troubleshooting multicast
A troubleshooting guide for multicast clusters can be found in Clustering.
