  2. 2. Control Plane Drivers Massive growth in traffic• Shift to unpredictable traffic patterns Cisco VNI• Lower CAPEX/OPEX• Increased availability requirements• Network layer consolidation• OSS integration 2009-14 Mobile data traffic 2014: 60% of mobile traffic will be video 2012: 1B mobile broadband connections Cisco VNI Pyramid 108% CAGR Cisco VNI Copyright © Metaswitch Networks | | 1
  3. 3. 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 Copyright © Metaswitch Networks | | 2
