DiffServ allows devices to mark network packets so that network devices can handle different types of traffic differently. This means that latency sensitive data such as VOIP or lighting control traffic can be prioritized on the network.
OLA supports DiffServ in some of the network plugins:
If you'd like others just ask.
To enable DiffServ support add
dscp = <value>
to the plugin preference file. e.g. to mark packets as Expedited Forwarding, use
dscp = 46
Future Work
Allow mappings of universe priorities -> DSCP values. This provides a flexible way of implementing backup controllers without provisioning extra network bandwidth. http://code.google.com/p/linux-lighting/issues/detail?id=76
