Enabling/Disabling Anonymous
mode (page 28)
Anonymous mode is used to hide the end user identities
(contact information of caller and callee) of Lync calls so the
Anonymous mode
end-users cannot be identified in all Net Optimizer - Lync
views (i.e. session table) and logs.
Viewing the Lync sessions
(page 34)
Net Optimizer - Lync provides detailed information about
Lync sessions and the QoS deployment result of each flow in
Presenting Lync
session details and
QoS results the Lync sessions. The session table helps you test your QoS
configurations and provides an important data basis for
further troubleshooting.
Viewing added Lync SDN
Managers (page 38)
The Lync SDN Manager list presents the IP addresses of Lync
SDN Managers registered in the Net Optimizer - Lync and
their reachabilities.

Viewing Lync QoE Metrics
statistics (page 39)
The QoE Metrics chart helps you measure the overall quality
of Lync calls initiated in a specific time period and provides
filtering to view the QoE Metrics statistics.

Viewing Best effort flow statistics
(page 41)
The Best effort flow table provides information about the
OpenFlow devices that Best effort flows occurred, the numbers
Best effort reason
analysis and statistics
of Best effort flows, and the reasons the application could
not apply a different QoS policy to those flows.
Licensing (page 13)Net Optimizer - Lync controls the number of users by license
and provides a grace allowance of 20% for Net Optimizer
License control
- Lync users. When the number of concurrent users in active
sessions exceeds the license limit of 120% of licensed users,
Net Optimizer - Lync stops performing QoS deployments.
Viewing event logs (page 43)The Event Logs function records events related to Net
Optimizer - Lync, and in some cases indicates that some
action is required to correct an issue.
Recording event logs
Switch flow interaction
Net Optimizer - Lync uses the following service flow:
1. When a user initiates a Lync call, the Lync SDN Manager in the data center provides the Net
Optimizer - Lync with call details, including source and destination IP addresses, protocol
type, application ports, and bandwidth requirements.
2. Net Optimizer - Lync uses OpenFlow to dynamically provision the end-to-end network path
and QoS policy for that Lync call.
3. After the QoS policy is deployed via OpenFlow, the call is connected to the destination client.
4. When the call is terminated by a client, Net Optimizer - Lync removes the policy from the
edge switch and recovers the original QoS settings.
Figure 1 shows an interaction of a typical Lync call (Clent A calls Client B via Lync) process.
