RTM SDN Overview
Chris LauwersUbicity, Founder and CEO
• 60% to 80% of Quality of Experience (QoE) problems with Real-Time Media (RTM) applications are caused by issues with the underlying network– Improper QoS configuration– Wireless access point issues– Interfaces between networks
• Administrators have limited tools for troubleshooting– Because of lack of network visibility
• RTM application developers have no options for taking corrective actions– Aside from error concealment
What is RTM-SDN
• Leverage SDN to Automate Quality of Experience
– Automated QoS marking
– Dynamic Traffic Engineering (SD-WAN)
– Automated Admission Control
• Leverage SDN to Automate Diagnostics
– Targeted monitoring
– Fine-grain monitoring
– Correlate endpoint quality data with network quality data
RTM-SDN Closes the Loop between RTM Applications and the Network
Trends in the Collaboration Industry
Jon SnyderCisco, Manager, Collaboration
Network Integration
Benefits• Self-contained; less reliance on third parties• Data and media stay within the organization• Control over version, services, etc.
Concerns• Operational complexity, lack of relevant skills• Upgrades can be slow and painful• Capital expenditures
On Premises Collaboration
Benefits• Pay as you go• Rapid feature velocity• Operated by vendor/partner
Concerns• Stability• Quality• Security
Cloud Collaboration

IT Challenges in Mobile Endpoints
Mani MahalingamPolycom, Distinguished
Engineer
RTM SDNNo application is as demanding as audio and video in end to end network behavior
• Audio is sensitive to latency
• Video demands bandwidth and latency quality
Is it Network, Service or Device endpoints?
• IT that manages the multimedia network wants to know
Challenges
• Lack of insight into network status and vice versa
• Limited opportunities for running session to adapt
RTM SDN
• Provisions three prime parameters end-end
• Flow-based network resource control
• UC application binds its session to network flow
Adaptation
• Network assures to the session parameters specified
• May adopt traffic paths as needed to fit resources
• Application may also renegotiate within constraints

Promise of SDN in real-time communications
Endpoints terminate a flow’s end-hops• Also true of mediated Conference flows
Endpoints• do not affect flow-elasticity
• Impacted by flow elasticity (latency, bandwidth)
In RTM SDN, endpoints enjoy benefits of• Set up by Application
• Enforced by Network (SDN Elements)
Endpoints & Cloud• Extends RTM SDN across providers
• Extranet flows provisioned Edge-Edge
