Current Trends
• Voice as a “standalone application” is going away
• SIP, SCCP, SVP, H323, Vocera, NoE
• UCC is the “new wave” in IT• Skype, Lync, FaceTime, Jabber, Hangouts etc. • Next “BYOD” problem
@ArubaNetworks

Why Microsoft Lync?
• Integration with AD, Outlook, Office etc.
• Unified mobile client for BYOD
• On-premise and Cloud based deployment models
• Enable collaboration with mobility
• Strategic partner and customer of Aruba

Challenges with UC over Wireless
• Diversity of Clients
• AV
• App incompatibility
@ArubaNetworks
• AP placement
• Channel Capacity
• AP Capacity
• Tx/Rx Characteristics
• Interference
• Mobility
• QoS on wireless • QoS on wire
• Queue overflows/drops
• Routing/path changes
• WAN
• UC server monitoring

Essentials to support Lync over Wi-Fi
• Classification & prioritization of Lync
• Wi-Fi optimized for Lync
• Real time and pro-active visibility

Types of Lync Deployments
• Lync On-Prem• Lync server farm is hosted on premise
• Hosted Lync• Lync server farm is hosted on a private cloud
• Lync Online• Lync server farm is hosted by Microsoft

Lync Classification Methods
• Heuristics
• SDN API
16 CONFIDENTIAL © Copyright 2015. Aruba Networks, Inc. All rights reserved#ATM15 |
Lync Classification using Heuristics
• Leverages DPI to identify & prioritize real time voice and video traffic
• Ideal for Lync online deployments• On-Prem deployments without SDN API can
leverage heuristics
• AirWave aggregates network wide data for visibility
Lync
17 CONFIDENTIAL © Copyright 2015. Aruba Networks, Inc. All rights reserved#ATM15 |
Lync Classification using SDN API
• Lync server integrates with mobility controller using SDN API
• Real time call info is shared with mobility controller
• Controller leverages the info to apply QoS
• Ideal for On-Prem Lync deployments
• AirWave aggregates network wide data for visibility

Call Details via SDN API
Lync
• CALL START• Caller/callee, device, session, BW, time etc.
• PERIODIC INTERVALS• Instantaneous Call quality
• CALL END• Avg. call quality, time etc.
