4 Licensing
Storage Keeping Unit (SKU)
Net Optimizer - Lync uses electronic licenses. Each electronic license is an SKU on the HP Corporate
Price List (CPL) that you can purchase indirectly from HP via resellers.
The number of electronic licenses you need is determined by the maximum number of concurrent
users with Net Optimizer - Lync licenses in active sessions. This number determines whether a flow
in a Lync session receives DSCP setting or goes with best effort. You can purchase electronic
licences at different times and from different resellers. The license that you purchase never expires.
An SKU for Net Optimizer - Lync comprises a product number and product description, as shown
in Table 5.

Product description
Lync licenses in active sessions. It can
also be multiplied by the number you
purchase. For example, if you buy four
of them, a maximum number of
concurrent users with Net Optimizer -
Lync licenses in active sessions is 400
(4×100).
Grace allowance
Net Optimizer - Lync controls the number of users by license and allows a grace allowance of
20% of licensed Net Optimizer - Lync users. For example, if you purchase a 100–user license, the
maximum number of concurrent users allowed in active sessions is 120.
License usages
The Licensing function monitors the number of concurrent users in active sessions in real time and
assigns licenses to these users. After the session ends, the licenses charged free up and the total
number of licenses available is recovered.
For example, if you bought a 100–user license and two users initiated a session, two licenses
would be charged and the remaining licenses would be 98. After the session ended, these two
licenses would free up and the total number of licenses available would be 100 again.
In general, licenses are charged as long as the flows in the session are not best-effort flows, and
the number of licenses charged is determined by the number of users in that session. However, in
certain scenarios, it is not easy to identify the number of licenses charged. Table 6 lists some of
these scenarios and clarifies license charging rules in ambiguous circumstances.

active sessions.
User A is in an active Lync session with user B, and at the
same time user B is in another active Lync session with user
C.
