Control Plane Drivers
2014: 60% of mobile traffic will be videoCisco VNI2012: 1B mobile broadband connections
Pyramid
2009-14 Mobile data traffic 108% CAGR Cisco VNI
Massive growth in trafficCisco VNI• Shift to unpredictable traffic
patterns• Lower CAPEX/OPEX• Increased availability requirements• Network layer consolidation• OSS integration

Multi-Layer Control Plane
• Multiple layers can include• MPLS-TP transport service sublayer• MPLS-TP transport sublayer• TDM layer (ODU)• WDM layer (OCh)
• Carriers use only the layers needed
• GMPLS is common

Trend: Control Plane in the Cloud
• Reduced cost with COTS hardware• Significant savings on server CAPEX & OPEX (eg power)• Open architecture• Simplifies control plane upgrades
• Merge control plane with incumbent OSS systems• Key requirement for tier 1 service providers• Eases the migration for transport groups from mgmt to control
plane model
• Centralized control for complex tasks• Multi-layer control plane• Lambda & OTN OCh routing
• Accelerated feature development cycle
