Overview of License Balancing and Redundant License Servers

Figure 3-1: Sample Redundant License Server Pool
Note that the license server computers do not have to be on the same subnet—
license servers can be in geographically separate locations on subnets connected
to one another via WAN, Internet, or dial-up connections.
You decide to evenly distribute license tokens among all three license servers (20
each), assuming that each group of employees will use the protected application
about the same number of times. This increases performance by distributing the
load between multiple license servers.
However, if a group of employees ends up having a higher demand for licenses
than the others, that group’s license server will borrow licenses from the other
license servers automatically. This improves performance because users will be
less likely to wait for a license from a distant license server.
To summarize: The configuration shown above uses redundant license servers to
accomplish two goals: license server backup and license balancing.
