More devices than capacity Sticky Clients Unpredictable Voice, Video & UCC WLAN Challenges for the Next-Gen Workplace

Internet Wi-Fi access point Wi-Fi controller LAN Lync Server Wi-Fi Clients 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 High Client Diversity BYOD Security and on- boarding Client Roaming not optimized Client do not support upstream tagging

UC / Application Admin Time in Weeks Ongoing Monitoring & Troubleshooting Identify traffic classes Configure UDP ACLs on Access Switches Inventory WAN circuit sizing What Codecs? Remark DSCP for untrusted applications? Lock down UDP ports ranges used for voice/video Identify sites Define Erlang traffic models Provision CAC across sites Review SLAs Ok, ready to start rolling out Enable DSCP …on all endpoints … Deploy across Campus & Branch Sites Network Admin

Wi-Fi Users use Lync with other Wi-Fi users and Wired Users

Yes … Its that Simple

NOTE: Clients do not support QoS by default QoS for wireless is automatically applied

Traffic streams as Lync voice, video and desktop sharing and tagged appropriately Traffic Re-tagging Voice, Video and Desktop sharing streams are appropriately tagged over LAN, WAN and Wi-Fi Traffic Prioritization Load balancing and Client Match ensure reliable voice and video communications Traffic Re-tagging Lync aware adaptive Radio Management, Airtime Fairness ensure optimal RF performance RF Optimization The SDN Manager sends in-call and post-call statistics to the controller SDN API Information

Aruba’s Approach to Lync over Wi-Fi Manageability Information on the system and AP utilization for Lync Centralized view of real time data on the call – caller, callee, R-value, packet loss, jitter etc Co-relate call quality with client Wi-Fi health metrics Historical call quality information for the AP and the users Real time information about other active sessions on the device for the user Identify call roaming events, tagging errors, device population Detailed diagnostics and monitoring data helps the IT team to manage, monitor and troubleshoot Lync over the Aruba Wi-Fi
