SDN Webinar & Panel Discussion Using SDN to Simplify and Automate UC and Real-Time Media Cloud Deployments
A welcome from our moderator Jim Burton Co-founder of CT Link LLC, UCStrategies and UC Expert Introducing our panelists today Manfred Arndt Hewlett Packard Enterprise, Distinguished Technologist Chris Lauwers Ubicity, Founder and CEO Mani Mahalingam Polycom, Distinguished Engineer Shambhu Rai Sonus, Senior Principal Product Manager Jon Snyder Cisco, Manager, Collaboration Network Integration
SDN Overview Chris Lauwers Ubicity, Founder and CEO
What is -SDN 60% to 80% of Quality of Experience (QoE) problems with Real-Time Media () 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 application developers have no options for taking corrective actions Aside from error concealment
-SDN Closes the Loop between Applications and the Network 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
Trends in the Collaboration Industry Jon Snyder Cisco, Manager, Collaboration Network Integration
On Premises Collaboration 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
Cloud Collaboration Benefits Pay as you go Rapid feature velocity Operated by vendor/partner Concerns Stability Quality Security

IT Challenges in Mobile Endpoints Mani Mahalingam Polycom, Distinguished Engineer
Promise of SDN in real-time communications SDN No application is as demanding as audio and video in end to end network behavior Audio is sensitive to latency Automated QoE Service 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 Set Forwarding Rules C B A Branch 2 Access Switch AP BE Wi-Fi Limited opportunities for running session to adapt SDN Provisions three prime parameters end-end Access Switch Flow-based network resource control BE UC application binds its session to network flow Adaptation Branch 1 Network assures to the session parameters specified May adopt traffic paths as needed to fit resources Application may also renegotiate within constraints
End points in real-time communications Enterprise Endpoints terminate a flow s end-hops Also true of mediated Conference flows Endpoints (diagnostics) UCaaS Provider do not affect flow-elasticity Impacted by flow elasticity (latency, bandwidth) In SDN, endpoints enjoy benefits of Collab Service NBI UC + SDN Controller Set up by Application Enforced by Network (SDN Elements) Endpoints & Cloud Extends SDN across providers Extranet flows provisioned Edge-Edge
