Application Classification and Metadata Engine

Qosmos ixEngine is a Software Development Kit (SDK) composed of software libraries, modules and tools that are easily integrated into new or existing solutions. Developers benefit from market-leading IP flow parsing technology to accelerate the delivery of application-aware solutions. Qosmos ixEngine can be used in all environments: physical, virtualized and in SDN architectures.

Qosmos ixEngine Architecture overview

Decoding Engine

  • Identification of protocols and applications behind each IP flow using a combination of advanced techniques including stateful inspection, behavioral and statistical analysis, heuristics, etc.
  • Extraction of metadata from protocols (e.g. volume, delay, jitter, etc.) and applications (e.g. name of file streamed on a website)

Protocol Plugin Bundle and Updates

  • Qosmos’ protocol plugin bundle includes thousands of protocol and application plugins to classify flows and extract metadata. Click here to learn more about protocol and metadata support
  • Qosmos Labs continuously monitor protocols and applications and apply changes to protocol plugins to ensure they are always up-to-date

Custom Signature Module

  • Allows users to develop custom protocol plugins that integrate in the Qosmos ixEngine framework at run time

Deep File Inspection Module

  • Identifies exchanges of suspicious files (i.e. incorrect / fake types or encrypted)
  • Performs basic checks for malware detection and Data Leak Prevention

Rule Engine Module

  • Executes customer-defined rules at run-time on output from classification and metadata extraction
  • APIs to configure rules and load them into rule engine at production stage; rules are expressed in JSON format


“We’re seeing continued interest in embedding DPI functionality in applications such as security, video optimization, and revenue and service assurance, which is driving demand for embedded solutions that provide advanced packet classification, such as Qosmos’ ixEngine.”
