Enhanced Service Enablement From flat fee to value based pricing models

OTT Monetization & Flexible Charging
Intelligent and context-aware traffic steering to value added service platforms based on a subscriber opt-in/opt-out model
Monetizing OTT services by flexible charging mechanisms and OTT partnerships for service differentiation Monetizing the subscriber relationship using big data (targeted ads, mobile payment)
Quality of Experience Management
Bandwidth controls, TCP optimization and context-aware traffic steering to optimization platforms for enhancing the subsciber’s quality of experience
16 © F5 Networks, Inc.
Quality of Experience Management Global and subscriber-based application control
Overall P2P = 10 Mbps Sub A “P2P” = 4 Mbps Sub B “P2P” = 4 Mbps
Sub C “P2P” = 4 Mbps
Sub A + B + C “P2P” = 10 Mbps
Even if subscriber is entitled for more by subscriber policy it gets limited based on the global policy
Gold Subscriber = 20 Mbps Rest = 10 Mbps
P2P = 4 Mbps
Even if subscriber is entitled for more by subscriber bandwidth policy his P2P traffic gets reduced to configured value (512kbps)
P2P = 512 kbps
Rest = 10 Mbps
