How do Floating licenses work?
Floating Licences are initially assigned to a particular MAC address on a computer, but are not restricted to it. They are instead pooled for dynamic use across a number of networked machines in a cluster. This allows you to buy only the number of channels that are needed for production use, regardless of the number of machines making up the production cluster.

The system operates using a robust, peer-to-peer system, which aggregates the number of channels licensed to each member of the cluster. All connected machines are aware of the number of pooled licences available, and are able to acquire and release licences as and when they need to.

This gives you load balancing and resilience without having to buy additional licenses. If one production machine fails, its associated channel licences are automatically available to other machines in the cluster.

Note that machines must exist on the same subnet. If a machine fails, nothing is affected (apart from a short delay before the licenses in use on that machine become available again). The only caveat is that once a machine goes down, there is a 2-day window within which to restart it, otherwise licenses associated with it will become invalid. If a machine is not recoverable, but its network card can be put in another machine, this will unlock its license. If this is not possible, you should contact Howler Support and we will reassign the license to a new MAC address on a new machine for you.
