Today’s UC&C Challenges
Network issues cause 60% to 80% of poor end-user QoE
Legacy Networks have poor visibility into real-time traffic• Lync uses encryption by default, making DPI difficult and unreliable
• Skype 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 user experience is only as good as the quality of the network”

Ongoing Monitoring &
Troubleshooting
Identify traffic
classes
Configure UDP ACLs on
Switches
Inventory WAN circuit

What Codecs?
Remark DSCP for untrusted applications?
Lock down UDP port ranges used
for voice/video
Identify sites
Define Erlang traffic
models
Provision CAC across
sites
Validate SLAs
Ok, ready to start rolling out
Enable DSCP…on all
endpoints
… Deploy across Campus & Branch Sites

OpenFlow enabled hybrid-mode• Enforce policies as traffic enters the
network• Supports phased migrations, since
rest of network can be legacy gear• Use SDN for new/difficult features
