Enabling All-IP flat architecture
! Massive increase of Throughput, Signaling and Density
! Need for an architecture that optimizes the investments, taking into account
Cost of transmission / routing Location of the Peering points Scalability of the EPC platforms themselves
! Flat IP architecture opens new possibility for network deployment. - Centralized versus Distributed
! True LTE subscriber profile is unknown today, Service mix is also to be confirmed
! Holistic view must include all technologies (E.g. including WiFi, Femto, etc.)
! Re-architecting the network today to prepare LTE is a “leap of faith”

! Purpose designed not an adapted product Call Servers: Designed for handling “high” processing
Routers: Designed for handling high bandwidth
Bladed architectures: Limited set of functions, scalability
! Harvests & applies all system resources to optimize performance & maximize capital efficiency
Processes distributed across the entire system
CPU resources are automatically adapted to meet needs
Single software image
• Simple, Elastic, scalability - Just one type of cards, no specific functional cards
- Linear scalability – all network functions & services scale with addition of single type of card
- Within the card, processing power elastically allocated between Signalling, Throughput, services
- Multiple collocated functions, single platform to manage, capacity elastically allocated among the different functions
- Single platform to manage, easy to maintain
PSC/DPC The only card needed for services and for expansion

! Single pool of CPU resources Drastically simplifies the planning effort. Throughput Vs Signaling flexibility:
During the day (ToD) As users behaviour evolves As new applications are launched As terminals behaviour evolves During unusual conditions
! Cisco EPC as a Control Point to manage signaling storms ! CPU gets automatically fully allocated to signaling during signaling
storms ! ASR5k typically never goes to overload during signalling storms ! Surrounding boxes may be impacted
! Cisco EPC supports Throttling, thus becoming the control point to manage a signaling storm
