3. Software Defined Networking:
Enabling The Mobile Workplace

4. 3+ mobile devices per user: strains network capacity
Sticky clients don’t roam well: bit rate and app performance degrade
Unpredictable client density: network must adapt to spontaneous collaboration
Wi-Fi Challenges In The Mobile Workplace

5. 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
• High Client Diversity
• BYOD Security and on-boarding
• Client Roaming not optimized
• Client do not support upstream
tagging

7. • QoS for voice, video, and desktop sharing Lync flows
• Real-time monitoring for voice and video call quality
• App RF technology enables Lync aware RF Management
• Remarks wired and wireless traffic with the right QoS levels

9. Better Visibility, Faster Root Cause Analysis
Managing Lync over Aruba Wi-Fi
• System and access point Lync
utilization
• Centralized view of real-time call data:
caller, callee, R-value, packet loss, jitter
• Correlates call quality with Wi-Fi client
health
• Historical call quality information for
users and access points
• Real-time per-device, per-user active
sessions data
• Identifies 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

10. Aruba Lync Dashboard Overview
Usage Trends Troubleshooting

11. Is the Problem Wi-Fi, or Something Else?
Wi-Fi Problem Something Else
All Good!

12. Identify Client Configuration Errors

13. User – “Jenny” – Calls Help Desk
User-Specific Trends
Individual Call Records

14. User – “Jenny” – Calls Help Desk – Troubleshoot Specific Call
QoS Modifications and Quality Scores

15. User – “Jenny” – Calls Help Desk – Troubleshoot Specific Call
Individual Call Details

16. Identifying Trouble Areas – Call Quality on a Floorplan

17. • Fosters mobility and collaboration by leveraging the Lync SDN API
to provide contextual awareness and auto-adaptation to users,
devices, applications, and locations
• Delivers fine grained visibility into client, device, and network
operation to expedite root cause analysis and problem remediation
• Delivers a better user experience wherever you work or roam
