A single LDK license can permit multiple RIPs to be run concurrently. This has some similarities with the use of permit files in HLS, but allows for significantly more flexibility.
Each RIP license has a defined activation count and concurrency:
- The activation count defines the number of computers that the license can be activated on. This sets the number of instances of the LDK licensing server that can run concurrently. Each activation results in a different Protection Key ID, because the Protection Key ID uniquely identifies the association of the license with a single computer (or dongle).
- The concurrency of a license defines the number of RIPs that are allowed to obtain their entitlement to run from a single activation on a single LDK licensing server.
The maximum number of RIPs that can be run from a single RIP license is therefore the product of the activation count, multiplied by the concurrency.
Normal LDK licenses for most OEMs will allow a single activation and a concurrency of 1, meaning that they will enable one RIP.
