  • 8. 3G/LTE Network Architecture OFDMA S1-u Serving S5 PDN Gateway Gateway HLR / HSS eNodeB MME InternetHSPA PCEF PCRF NodeB luPS Gn RNC SGSN GGSNHSPA Radio Access Network Packet Core IMS / Internet Source: Earlswood Marketing
  • 9. Multicore Processor Options• General purpose multicore processors • X86 architecture • 4, 6 or more cores (12 or more virtual cores) • Closely coupled memory banks • DPI enhanced by SIMD cores and instruction extensions • Intel Data Plane Development Kit (DPDK)• Integrated multicore processors • Up to 100 real or virtual cores (MIPS or PowerPC) • Enhanced DPI performance with new 64-bit cores • Integrated cross connect switch • High speed memory and networking interfaces • Offload engines & network accelerators• Network Processors• FPGAs
  • 10. Standardized Platforms• Carrier Grade Server Systems • Rack mount or blade servers • Based on x86 multicore processors • Need discrete switching and load balancing systems• ATCA • Carrier grade telecom platform • Widely used for IMS and 3G/4G packet core • Support for all types of multicore processor • Scalable platform • Integrated 10Gbit/s or 40Gbit/s switching
  • 11. DPI Market• Standalone market growth • 30-50% CAGR• Key trends • Fixed drove market early on • Mobile most significant 2012+ • Strong Far East growth • Includes PCRF• Take-aways • Existing networks key, especially 3G • Fixed vs mobile architectures Source : Infonetics 2011 Others available at http://broabandtrafficmanagement.blogspot.com/p/dpi-market-size-forecast.html
  • 12. Radisys Role in PCEF & DPI Macro -> Femto  10G ATCA -> 40G ATCA  Dumb -> Smart Pipe  VoLTE Small Cells  SEG: Secure Backhaul  Better QoE  A/V VAS 55+ Licenses  ~40% ATCA Market Share  ATCA Leader  ~60% Share
  • 13. Expanding PCEF Capabilities Tiered SLA Aware (Platinum vs. Gold) RAN Application Congestion Aware Aware (Conversational vs. Streaming Video) Policy Device Access Aware Aware Enforcement (Tablet vs. (Macro vs. Femto) Point Smartphone)DPI = Different Classes of Service + Traffic Optimization + Tiered SLA
  • 14. DPI Applications Beyond PCEF Mobile Fixed Charging PCEF Subscriber Security Mgmt PCRF DPI Video Offload IOG LI FGW Monitoring…in reality market opportunity for DPI significantly larger than PCEF…plus many of these inter-connect or leverage same architectures
  • 15. Data Growing…is Gap Reducing ? Revenue vs. Traffic Growth Traffic Revenues & Traffic Gap Narrow (?) Voice Era Revenues Data Era Traffic Doubling every 12 months  End of ‘unlimited’ plans Video = Operators’ Albatross  Revenue increase : sharing business Text models & tiered services introduced  Moores law : lower cost/bit Source: Cisco VNI Source: Heavy Reading
  • 16. PCEF Scalability Paradigm Integrated Edge Routers Fixed 300-500GCapacity 40-100GbE LTE 100G+ Number of Ports Port Speed 10-40-100G Overall Platform Cost 3G 10-40GbE Expansion Capabilities 10-40G Protecting existing CapEx Cost / CapEx
  • 17. Audience Poll #1When will PCEF systems require 100GbE ports? • Using already • 2012 • 2013 • Later than 2013 • Never
  • 18. PCEF Platforms DecisionsFuture Integrated Edge Router AdvancedTCA (40G) Carrier Grade AppliancesToday Integrated Edge Routers Enterprise Servers AdvancedTCA (10G) Proprietary Appliance Appliance inc. clustering Small Medium Large <10Gbps 10-100Gbps 100Gbps
  • 19. Anatomy of PCEF Network PCRF Mobile CoreManagement Policy & Reporting Application Usage Reporting & Statistics Configuration & Policy Mgmt Application Trillium e.g. Diameter System Mgmt inc.

  • 20. High End AdvancedTCA PCEF System Mgmt 16 x 10G Port Policy Engine Density IO LB Up to 64 x Hub Policy Engine 10G IO LB Switch Policy Engine Future IO LB Policy Engine 100GbE Hub ports … IO LB Switch Policy Engine Policy Engine 16x 10G Policy EngineNetwork IO Load Balancer Application ID & Policies 640Gbps 300-400G ~ 320G Adjust LB vs Policy Engine vs Chassis Size (2-6-14 slots) To reach given capacity requirements
  • 21. High End PCEF – The Alternatives • Proprietary ? • OK if you are Tier 1 with volume – and even then it can be expensive to re-use inhouse platform • Tier2/3, ROI usually too low unless R&D vs Revenue significantly increased…shareholder support ? • Blade Servers • CPU capacity is OK, but with external load balancer • Adding external load balancer introduces significant cost and complexity
  • 22. Transitioning to 100GbE• Market is starting a move towards 100GbE • Catalyst will be widespread introduction of small form factor, low cost optical modules such as CFP2• Stand-alone PCEF influenced by edge routers • Connectivity mostly CFP today, which is too large and costly for commoditization, especially in-building• 2H 2012 / 2013 sees migration to 100G switches • This is catalyst for stand-alone PCEF to move to 100G • Short term 100G (10/10, 10/12) cables an alternative
  • 23. Medium Capacity PCEF’s …migration from blades to appliances FRU Serviceability  2U 19” Rack Mountable IO, PSU, Fans Commerial  NEBS certified HW accelerators Network Appliances  20” deep (600mm cabinet) Fully managed  Long lifecycle parts Carrier Grade PCEF for Mobile Networks…… …scalable from 10-40Gbps …cluster for 100Gbps+
  • 24. Traffic Management• Critical to overall QoS & efficiency• Integral part of end to end policy strategy• LTE expected to drive requirement from software to hardware
  • 25. Traffic Management• 5 Level Hierarchy• Maps flowsports (Millions per system)• Network processors feature heavily in proprietary integrated solutions (Edge Routers with DPI/PCEF)• Future PCEF & standards based network elements will need capability
  • 26. Traffic Management Integration Packet Processor (Load Balancer/Session Processor) DIMM CPU RTM PCIe x8 / ILA Traffic Manager CPU DIMMSearchMemory Egress Fabric Buffer NPU TrafficMemory Shaping Ethernet Switch StatsMemory Ingress Pre-processing
  • 27. Audience Poll #2What is your view on PCEF in LTE Networks • Stand-alone PCEF will be most common • PCEF function will reside in P-GW • PCEF will be in separate edge routers • LTE has enough capacity to not need PCEF • Traffic management will replace PCEF
  • 28. Conclusions• PCEF remains strong, growing market • Stand alone & integrated both have role to play• Creating & leveraging markets for network probes• Fixed & mobile PCEF requirements differ, and potentially so do the fulfilment platforms• Bladed solution gain strength, ATCA diversity key• New architectures complete solutions • Carrier grade network appliances • Hardware based traffic management solutions
