5. Network Monitoring for QoE • Post-session statistics • Harvested from end devices • Harvested from centralized servers • Historical information to predict future issues • Network probes • Geographically deployed • Overlayed on operational networks • Intelligent edge devices and endpoints • Proactive measurement of network quality • Proactive alarming and reporting of quality degradation • Embedded throughout network for holistic coverage • Integrated with network, rather than attached to network

6. SLA Mon Architecture—Agent • Agents embedded in devices (phones, gateways, data products and soon bridges and other media application layer elements) • 96x0 (since R3.1 SP4) • 96x1 SIP (since R6.0.2 for v1 and R6.2 for v2) • 96x1 H323 (since R6.0.2 for v1 and planned for R6.3) • G430 and G450 (currently in SV) • VSP9K and 56xx (currently in development) • Bridges, signaling elements and soft clients projected

7. SLA Mon Architecture—Server • Server controlling the agents that are registered on it • Agent will only register with a server if it can authenticate the server • The registration process is used to exchange a private key used by the agent to decrypt and authenticate server commands • The registration process is launched from the server by sending an agent discovery packet • Server interaction with the agents is through encrypted and authenticated UDP based proprietary protocol • Server maintains historical data • Server interaction with the user is entirely through HTML5

9. Real-time Application Monitoring • End-to-end QoE management of the IP network • Proactive testing of end-to-end communications paths • SLA Mon • Perform tests and verifications when and where they matter at all layers in the topology • Integrates diagnostics capabilities into end devices and network hardware- no probes • Differentiators • End to end session media topologies • Tracing DiffServ source to destination • Analyzing DiffServ (loss, delay, jitter) to compare network performance across multiple DSCP values • Real-time packet capture of exchanged DHCP, LLDP and (soon) media signaling packets End-to-End Management End to End Latency/ Jitter Unified Management Enterprise LAN Enterprise WAN

10. Proactive QoE MonitoringOverall Network Performance • Shows network locations on world map • Displays individual site performance as well as the relational performance among sites • Tests the connections for jitter, delay and loss for audio, data and video • Proactively find service-impacting conditions that can be resolved to improve the network performance

11. Getting to the Root of the ProblemPinpoint WHY You’re Having Network Issues • Quality of Experience Matrix displays end points and connection details • Green cells indicate that traffic is going from the source to destination correctly • Red cells indicate all traffic going into the site is incorrect • Provides performance factors including delay, jitter, packet loss, remarking, etc. • Displays audio, video, and data queues and associations

12. Performance Map

13. Enabling Issue ResolutionSolve and Prevent Chronic Issues • Service Level Agreement (SLA) Monitoring provides network quality statistics • SLA Mon tracks all of the packets and identifies where the problem occurs with packet transformation • Runs end-to-end tests and measures results • Traces through network identify performance factors such as remarking • Session maps performs end-to-end call trace showing end points and gateways 13

14. Enabling Issue Resolution

15. DSCP Tracing • Unique ability to trace the IP header DSCP values from source to destination • Pin points devices that change the DSCP marking and how • Describes the relationship between the DSCP trace and the end-to-end performance obtained for packets of different markings • Server keeps long term historical data about paths, DSCP traces and performance

16. End-to-End Performance Summary • Simple Real Time Matrix representing end-to-end summary for all aspects of performance

17. End Device File System Browsing • Simple HTML5 interface to navigate the device file system • Extract files on the fly • V2 agent capability

18. Device Remote Control • Remote control of device • Access to craft and other menus • Inject keyboard and touch screen events • Capture events injected by user • V2 Agent capability

19. Packet Capture • Perform packet capture on the fly (no hub and no port mirroring necessary) • Extract boot time DHCP and LLDP packets • Control capture to include or exclude media payloads • V2 Agent capability

20. SLA Mon: Ease of Support Use Cases Scenario: Apex Company’s most strategic customer is hosting an event where there will be a significant increase in voice and video traffic. With Avaya SLAMon… • Real-time traffic is simulated to proactively measure performance • Potential issues and their root cause is easily identified Changes are implemented prior to the event Proactive performance monitoring addresses issues before they arise

21. OIS: Giving You the Information You Need Instant network oversight • Single glance view • Unified, real time dashboard • Zoomable map with customized information Home Easy to access information • Web-based solution • User sites and information • Easy to navigate site pages • Network alarms • Drill down reporting/capability

22. Avaya OIS- Proactive Monitoring

23. OIS: Network Control and Monitoring

24. OIS: Reducing Downtime Stop issues before they start • Incident status • Trending summaries and historical reporting • Closed incident detail Incidents Full visibility into issue resolution • Incident detail • Time to resolution • Filter by incident type • Incidents by initiated 24

25. OIS: Product Lifecycle Control Full insight into product status • Site product inventory • Critical patches available • Firmware/software version • End of Sale status • Extended Support status Life Cycle Keep your systems up to date • Firmware/software installed Quickly find what you’re looking for: • Sorted by solution element • Sorted by site location • Filter within location 25
