The Evolved Packet Core (EPC) and related Diameter Signaling Controllers (DSC) composite applications are ripe for disaggregation.  Advances in virtual network acceleration promise to allow even the EPC Data Plane to run on standard high-volume COTS cloud servers.

In order to gain experience, CSPs are hardening limited-scale vEPCs and vDSCs for emerging services like the Internet of Things (IoT).  The captured learnings are clear: granular, real-time vEPC analytics are sorely missing.

SONAR4 fills the vEPC Analytics gap by delivering:

  • deep, real-time visibility of these newly virtualized composite applications across their entire technology stack, and
  • closed-loop feedback to Orchestration functions.
