•  MVG Video Pacing MVG sold and deployed in a Tier 1 US customer Video data transmission savings of 26% (average) Overall data transmission savings of 6% (average) No issues reported by subscribers No capacity/functionality impacts reported Reduces overall throughput load on system – has positive impacts to capacity planning exercise

•  MVG + VDS OE MVG + Video optimization in a European Operator

23% reduction in overall traffic (of which less than 30% is video)

PDN/ Internet

RNC functions migrated to eNB and EPC •  NB signalling aggregation -> MME (e.g. paging fan out, intra LTE HO)

•  NB user plane aggregation -> SGW (e.g. intra LTE HO)

•  User plan ciphering -> eNB

•  NAS signalling ciphering -> MME


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


•  Session recovery for common services -  Software task recovery time is 2 seconds or less

•  Carrier grade architecture -  Any terminated task will be restarted -  State will be recovered/verified via consistency audits

•  NEBS Level 3 certification •  99.9999% reliability (6 nines) •  Stateful inter-chassis redundancy

-  Nodal redundancy due to catastrophic failures -  Power outages, fiber cuts, loss of routing table -  SW upgrades across major software versions
