4. ©2014 Extreme Networks, Inc. All rights reserved. The Challenge With Lync  Deployment requirements are complex  Often involve separate UC, application and network owners  Lack of visibility into performance, metrics, and diagnostics  Low quality experiences slow adoption, increase trouble tickets, reduce ROI More Than Instant Messaging

Lync SDN API passes Source – Destination IP UDP Ports used by RTP Type of Call 3. OneFabric Connect locates devices and users and creates dynamic profile on the switch that applies QoS to the flow/call Each Packet is marked for QoS throughout the network Leverages existing QoS mechanisms in the core Lync Controller provides ongoing information to Extreme NetSight on Jitter and MOS 5. Call Termination Remove QoS A Add MOS data to end Report End to End QoS and Contextual Reporting Solution Microsoft Lync SDN Integration with OneFabric Connect API

12. ©2014 Extreme Networks, Inc. All rights reserved. SDN integration - Why does it matter for Lync?  Prioritizing MS Lync based on UDP port ranges or DSCP does not work reliably –UDP port ranges can accidently prioritize other applications using the same ports, results on QoS degradation for MS Lync –DSCP based marking is only supported on MS endpoints, no support for iOS, Android etc  See also Microsoft TechNet –Enabling QoS in Lync Server 2013 for devices that are not based on Windows. By default, QoS is disabled for computers and other devices (such as iPhones) that run other operating systems. Although you can use Lync Server to enable and disable Quality of Service for devices, you typically cannot use the product to modify the DSCP codes used by these devices. –Configuring Quality of Service policies in Lync Server 2013 for clients running on Windows 7 or Windows 8. Note that Microsoft Lync Server 2013 does not support QoS for other Windows operating systems, such as Windows Vista or Windows XP.  Contextual reporting is not available without SDN integration and concurrently NAC deployed 12
