What Do All These Things Have In Common?


By 2017, mobile data traffic will reach 11.2 EBs/month (134 EBs annually). In 2012, mobile data traffic grew 70% (YoY).

By 2017, there will be more than one mobile connection (10.3B) for every member of the world’s population (7.6B).

Mobile connection speeds doubled in 2012; will increase 7-fold by 2017. By 2017, 4G will account for 10% of connections, but 45% of mobile traffic.

By 2017, over 66% of the world’s mobile data traffic will be video.

In 2012, cloud was 74% of mobile data traffic; will be 84% by 2017.

Global Mobile Data Traffic

In 2012, 33% of mobile traffic was offloaded; by 2017, 46% will be offloaded.

Unique Conditions Affect Each Region’s Mobile Data Traffic



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”

RNC functions migrated to eNB and EPC

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

• User plan ciphering -> eNB

• NAS signalling ciphering -> MME


Key Benefit of Integrated, Elastic Architecture

• Single pool of CPU resources

• Drastically simplifies the planning effort. Throughput Vs Signaling flexibility:

• During the day (ToD)

• As users behavior evolves

• As new applications are launched

• As terminals behavior evolves

• During unusual conditions

• Cisco EPC as a Control Point to manage signaling storms

• CPU gets automatically fully allocated to signaling during signaling storms

• ASR 5000 Series typically never goes to overload during signaling storms

• Surrounding boxes may be impacted

• Cisco EPC supports Throttling, thus becoming the control point to manage

a signaling storm
