Rich colors

Life happens in color. Color captures passions,inspires emotions, and connects people. Bright and energetic,pure and beautiful, the Microsoft colors add vibrancyto communications and are among the most recognizableand unifying elements in our visual identity.

3+ mobile devices per user - BYOD

Unpredictable Voice, Video and UC traffic over mobile devices

Sticky clients don’t roam well

Wi-Fi Challenges in the Mobile Workplace

Common UC Over Wi-Fi Challenges

•Wired network may lose traffic priority indicators

•Legacy wired network may incorrectly tag traffic

•UC Servers are often not configured to tag

Client Side Limitations

Wi-Fi Limitations Wired LAN Limitations

• RF is a limited bandwidth resource

• WMM traffic prioritization depends on wired network prioritization.

• No troubleshooting capabilities for Lync (multiple media types in 1 encrypted stream)

•High Client Diversity

•BYOD Security and on-boarding

•Client Roaming not optimized

•Client do not support upstream tagging

Aruba with Lync: Heuristics or SDN API

Heuristics based detection – Lync traffic is identified based on known characteristics of Lync Voice and Video. As the Lync traffic traverses the controller it is inspected and classified as either Voice or Video and the appropriate QoS settings are applied to them.(UCOIP: http://technet.microsoft.com/en-us/lync/gg131938 under Networking)

SDN API based detection – Lync traffic is identified through the integration between the Lync Front End server and the WLAN controllers via Microsoft’s SDN API. The Lync front End server sends messages to the Aruba Controller identifying Lync traffic by type and endpoint. (UCOIP: http://technet.microsoft.com/en-us/lync/hh972602 under SDN)
