Qosmos® showcased DPI technology implemented as a Virtual Network Function Component (VNFC) within a virtual Evolved Packet Core (vEPC) framework for 4G broadband mobile networks at the recent Mobile World Congress. The virtualized DPI (VNFC) analyzes network traffic in real-time and in detail, and feeds resulting information to a virtual PDN-Gateway that can trigger multiple functions such as quality of service (QoS) management or traffic shaping. The solution which is composed of a reference architecture developed by Intel® and in accordance with ETSI NFV principles, enables EPC developers to benefit from rapid time-to-market while telcos profit from integrated intelligence to optimize network services.
Using the Qosmos's Element Management System, the DPI VNFC technology can be implemented in an elastic way, whereby it can send behavioral traffic information to the orchestrator/analytics system to trigger events, such as scaling up (add vCPU to the VM instance) or scaling out of virtual machine (VM) instances.

According to a statement by Qosmos, using the solution operators can optimize costs through improved equipment utilization while securing service level agreements (SLAs) through dynamic and rapid instantiations. And this would translates into significant OpEx cost reductions associated with, for example, the PDN-GW and implementation of disruptive service provider mobile plans such as tiered pricing, application charging, etc.
“We are currently facing strong demand from the industry for commercial NFV solutions that can be deployed quickly and easily,” said Jerome Tollet, CTO at Qosmos. “This demo shows DPI technology as a virtualized component which can be easily configured and will scale elastically to meet changing network conditions.”
