Lync Like You’ve Never
Seen It Before
Wi-Fi Challenges in the Mobile Workplace
3+ mobile devices per user - BYOD
Unpredictable Voice, Video and UC traffic over mobile devices
Sticky clients don’t roam well
Common UC Over Wi-Fi Challenges
Client Side Limitations
Wi-Fi 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
• High Client Diversity
• BYOD Security and on-boarding
• Client Roaming not optimized
• Client do not support upstream
tagging
encrypted stream)
Wired LAN Limitations
• Wired network may lose traffic
priority indicators
• Legacy wired network may
incorrectly tag traffic
• UC Servers are often not
configured to tag
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.
