6. Visualize, Why Does it Matter?
Monitor/Enforce application SLAs
Define global, network-wide application performance policies in minutes instead of days
All from a single centralized platform
Ability to drill down to flow level

7. Act Per Session for Dynamic QoS
Each user session per business application is protected without impacting the next user, regardless of the application mix and network conditions
Bandwidth allocation is performed dynamically considering global performance objectives vs jitter, packet loss and latency on the network
Dynamic queues for each session

SharePoint
Skype for Business
WAN Link

8. Improve Path Selection, Why Does it Matter?

9. Real-Time Decisions Should be Based on Multiple Factors
Application Performance
Application Performance Objectives
Real-time
users’ activity
Real-time assessment of network performance
Application Performance Objectives
Business criticality
Type of traffic (real-time, transactional, etc.)
Minimum bandwidth to guarantee for each flow
Actual users’ activity
Idle (e.g. reading or typing)
Stable (e.g. voice)
Elastic (e.g. data transfer)
Real-time traffic situation
End-to-end network capacity
End-to-end network quality
Traffic matrix

10. Analysis of End User Experience
Ms-office-365 has a high WAN delay & RTT
Problem starts at 9:45
- Performance issue identified on the SaaS group
Drill down to investigate who and which application
Office 365 takes a large par of the network for a specific conversation => investigation of the usage should be done with the user & higher priority should be assigned to Office365
Evolution display to see the impact in the past and validate the point

11. Measuring and Enforcing Application Performance Matters
Accelerating Troubleshooting (end to end drill downs beyond applications including infrastructure)
SLA Enforcement (via Control/QoS and sophisticated Dynamic WAN Selection techniques)
Visualize Performance (real-time flow level dashboards and reporting)
