Traffic shaping capabilities

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

Determining the priority

• Subscriber focused statistical function

• Provisioned/static priority– Emergency services– VIP– Etc

• Dynamic priority– Most important subscribers– Most revenue generating subscribers– Devices

Mediation in EPC

• Multiple protocols/interfaces

• Conditional mediation and operation chaining

• Stateful operation

• High performance and flexibility

Security

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
