Enterprise-ready

11. Today’s UC challenges
Network issues cause 60% to 80% of poor end-user QoE
Legacy Networks have poor visibility into real-time traffic
• Most UC deployments use encryption for security, making DPI difficult and unreliable
• Some UC vendors tries to hide itself from networks
Traffic engineering & QoS is complex…easily broken
• Requires brute force static policies that must match application server settings
• Intermittent problems are tedious to diagnose, especially for Softphones and BYOD
“Quality of the user experience is only
as good as the quality of the
network”

18. UCI Forum UC SDN Charter
Pain Points
60% to 80% of QoE problems are caused by issues with the
underlying network
• Inadequate QoS Infrastructure
• Complex root cause analysis between networks and UC components
• Network Middleboxes and Security
• Network Virtualization
