DPI as Virtual Network Function Component (VNFC)

Qosmos DPI as a Virtual Network Function Component (VNFC) complies with an official use case standardized by ETSI in July 2013. This new Qosmos product runs in a virtual machine and uses optimized interface to feed application information and metadata to other integrated components, together forming virtual networking equipment (VNFs) such as Service Routers, GGSN, PCEF, BRAS, ADC/Load Balancers, Network Analytics, NG Firewalls, WAN optimization, etc.

Qosmos DPI VNFC is based on Qosmos’ flagship product ixEngine®, which is already established as the de facto industry-standard DPI engine for developers of telecoms and enterprise solutions. ixEngine identifies and extracts information traveling over networks in real time, providing a true picture of the traffic by identifying protocols, types of application, and extracting additional information in the form of metadata. Equipment makers, telco and enterprise software vendors, and cloud service providers use Qosmos to gain application awareness, accelerate time to market and benefit from continuous signature updates.

In a telecom environment, Qosmos DPI VNFC can optimize a virtual Evolved Packet Core, by feeding real-time traffic information to a virtual PDN-Gateway that can trigger multiple functions such as quality of service (QoS) management or traffic shaping.  This means that operators can optimize costs through improved equipment utilization while securing service level agreements (SLAs) through dynamic and rapid instantiations.


  • Short time-to-market for solution developers
  • Safe implementation: VNFCs de-correlated from DPI software and signature updates
  • Improved flexibility (VM migration)
  • Elastic scalability (up & out)




“Qosmos has been the gold standard for embedded DPI and related applications. With their recent work in NFV, they’re leading the market into the critical area of DPI as a service, and facilitating the integration of SDN and NFV into a common and more compelling revolution in networking.”
