Multicaster Project

The Multicaster project is aimed at helping developers/engineers to diagnose whether sACN/multicast networks are well configured. In a badly configured network (where multicast is being converted to broadcast), everything will seem fine until it breaks.

Artistic Licence has written a small Windows programme that allows one to test whether a network is properly configured for multicast. Called Multicaster, it connects via two network interfaces both connected to ports on the same switch. That allows Multicaster to send packets and analyse the results.

Please consult the following articles for more information on the problem and how to use the software.
