Configure multicasting

Enable multicasting in Stone and Wire. Unnecessary if upgrading an existing installation of Burn.

1. Open the /usr/discreet/sw/cfg/sw_probed.cfg configuration file on the render node in a text editor.
2. Set SelfDiscovery to Yes. Now sw_probed runs in self-discovery mode and it will automatically probe the network for other systems. This is set to Yes by default when Stone and Wire is installed on the render node.
3. The Scope parameter defines the scope for the multicast. This parameter setting must be the same for all machines on your network.
   • For networks with one subnet, set to LinkLocal.
   • For networks with subnets, use a value that is appropriate for your requirements and router configuration, either OrganizationLocal, or GlobalWorld.
4. If the workstations and Burn nodes in your facility are on separate networks connected through routers, use the ttl parameter in the file to specify the number of router hops for a multicast. Burn-related transfers across multiple routers may cause bottlenecks at network bridges, especially with jobs involving film frames. Using the ttlparameter may reduce multicast-related traffic and improve general network performance in your facility. Consult your network administrator for guidance on setting the appropriate values for your network.
5. Save and close the sw_probed.cfg.
6. Restart the sw_probed daemon: /etc/init.d/stone+wire restart.
