Traffic shaping
• Guarantees predictability of the volumes
• Keeps investment under control
• Ensures network service availability
• Guarantees QoS though smart prioritisation
techniques
• Mobile data and smartphones drive change in signalling profiles
• Signalling storms have become a reality
• All parts of the network should function under any condition

To be ready for tomorrow requires attention and planning today
Take advantage of secure transport (IPSec/TLS/DTLS)
Apply topology hiding at interconnects
DoS attacks protection, through DEA
Packet integrity: Improve network efficiency by enforcement of
protocol usage and parameters to an application
Enables additional levels of SLA policy enforcement

Consumer behavior evolution is driving the change:
New devices
Ne style of communication (OTT)
Introducing new technology to the daily business such as Smart City concepts enabling: New ways of doing standard things (parking, metering, garbage collection)
Emphasize smart ways of network architecture and management vs simple capacity extention
Commodity HW or Cloud based solutions
Evolution to EPC is the industry response
Flexibility of the protocol allowed to build dedicated interfaces for each core network function: good for separation and localization of a specific functionality, but introduces a challenge in the management of this infrastrcutre.
Talk on this slide and continue introducing signaling storms.
Behavioral aspect of mobile user is also evolving.
The main signaling storm industry has faced before were largely tight to festive communication peaks between mobile users,
While today, these storms are becoming daily reality due to new usage profiles
DSC is in the center of the network what makes it a logical place to implement different techniques to deal with this fenomena,
This does not limit mobile operator to limit their business priorities that might be different at a given moment in time.
- Congestion situations, give a sample on WiMAX user.
Integration of different elements and functions in the network potentially using different protocols
Changing the interface elements depending on the congestion status of the destination systems
Packet integrity
Management of not only network elements but also diameter applications.
STP is just routing, while here we are talking about much more functionality
