HP Network Optimizer SDN Application - Microsoft Lync 1.0 Administrator Guide
1 Net Optimizer - Lync overview
The HP Network Optimizer Software Defined Networking (SDN) Application - Microsoft Lync (Net
Optimizer - Lync) is built on the robust HP SDN base platform called HP VAN SDN Controller,
acting as an external component. With the cooperation of the SDN Controller, Net Optimizer -
Lync enables DSCP marking and flow monitoring to implement best path routing, consistent Quality
of Service (QoS), and bandwidth guarantee for Lync calls.
In a traditional network, QoS policies for all network services are predefined by the network
administrator and cannot be changed by client users. As a widely used, unified communications
solution, Microsoft Lync is one of the most popular network services in networks of various scales.
QoS deployment for Lync service is complex and closed related to communication quality.
The Net Optimizer - Lync is an innovative SDN application enabling automatic QoS deployment
on a dynamic basis for Lync calls. It allows you to define DSCP values for various Lync services,
including voice calls, video calls, and application sharing. Once a Lync call is initiated, Net
Optimizer - Lync automatically applies the predefined DSCP values to the corresponding flows on
edge switches using OpenFlow to deliver a better user experience and reduce operational costs.

Configuring hard phone VLANs
to not be applied with QoS
Specify Hard phone VLANs. Net Optimizer - Lync cannot
deploy DSCP marking to the Lync flows from or to a hard
phone in the specified VLANs.

Configuring gateways for
crossing SDN domain boundary
(page 27)
The gateway information should be added to the gateway
list so that Net Optimizer - Lync can apply QoS policy to the
Lync calls across different SDN domain boundaries.

to the Lync calls and provides the QoS deployment result for
each Lync flow.

Net Optimizer - Lync can only collect Lync data from the Lync
SDN Managers registered in it. Registering a Lync SDN

Configuring Lync FE servers
(page 30)
Adding the static IP address of Lync FE servers enables Net
Optimizer - Lync to push a control rule to these Lync FE servers
for prioritizing Lync traffic.
