1. An IoT model to UC Events in SDN
environment – On-premise and Cloud
Darren Gallagher (Unify Inc.)
Mahalingam Mani (Polycom Inc.)
Chandrashekhar Rao (Logitech Inc.)

2. Bases of IoT
• Machine-to-Machine (m2m)
• Technologies that allow both wireless and wired systems to
communicate with other devices
– Communication-enabled Business Processes
• minimizes/eliminates human latency existing within a process
or workflow.
CEBP in UC service orchestration is UC IoT
• May lead to pure UC actions (e.g., start conference)
• May cause UC sessions to modify/tune other
services (e.g., lighting/temperature in a room)
Overview

3. • Long-term data gathering across IoT elements
• Drives huge potential for analytics
• E.g.: UC SDN model as virtual IoT (sensors & actuators)
• Patterns for predictive diagnostics of network faults
• Human-centric automation
• humans and machines will work together to create better
outcomes that neither would be able to do as capably on
their own
• Real-time & in-session responses to events
• Join/leave conferences
• Diagnostics on Collaboration components
– Diagnostics on Network itself
Other aspects of (UC) IoT

4. Charter goals in Brief
• Be a forum for IoT & M2M info-exchange for IMTC
• Build a library of use cases
• Arrive at an UC-applicability profile
• Liaise with choice SDOs & Industry Alliances
• Collaborate with related Activity Groups within IMTC
• Work on test-plans & interop. Testing

8. Overview of UC SDN
• Two facets of UC Flow control
– QoE (
– ADS (automated diagnostics)
• QoE
– QoS
• Prioritizes packets across flows
– Admission Control
• Reserves & prioritizes flow
– Traffic Engineering
• Reroutes around faults in path

10. Automated Diagnostic (ADS)
• Traditional / standard measures
– RTCP feedback
– Synthetics
– Probes
• Shortcomings
– Useful but incur latencies
– Less/late insight into network status
– Endpoint or Network at fault?
• ADS extends QoE framework
– Supplements Endpoint feedback
– Network sends status up to UC App
– App/ADS analyzes & correlates

13. • How does a virtual IoT model help with UC SDN?
– Network Events are mapped as virtual sensors
– QoE Flow configurations are mapped as virtual actuators
• Synergies in Stack
– Correlation of Diagnostics information from network
– Correlation of events using Policies
• IoT Extends Applicability on Endpoints to Network
• Helps view SDN as an embedded field of IoT elements
– Similar to Endpoint diagnostics delivering health events
