Critical Application Performance Criteria Troubleshooting Path Selection Visualize Application QoS Ensuring end to end Application SLAs Display real-time flow level performance Efficient problem resolution Select best path per application needs in real-time

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

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 WAN SharePoint Skype for Business WAN Link

Improve Path Selection, Why Does it Matter? Datacenter WAN Match business objectives to real-time network conditions Eliminate chronic blackouts/brownouts Outlook Skype FB Video VDI Internet MPLS Skype FB Audio Get 99.9%+ on application uptime and performance Ensure most efficient and optimal treatment of applications

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

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

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)
