Service assurance

THE RIGHT INFORMATION AT THE RIGHT TIME WITH BUILT-IN DPI

Service assurance solutions need very specific, detailed information on network performance, such as delay and packet latency, in order to compute Key Performance Indicators (KPIs). In addition, they need to be able to carry out investigations through different angles: per individual subscriber, per handset type, per data content or per network element for example. This level of detail and analysis requires very granular information on network traffic, including protocols and application metadata.

 

QOSMOS NFV PROBE

Qosmos DPI-based technology is designed to identify the application behind each IP session and deliver detailed metadata from protocols and applications. The Qosmos Probe provides this information in a package adapted for developers of Service Assurance solutions. Relevant metadata is available either in real time, via an API, or from a standard database with an open data model. The Qosmos NFV Probe also supports fast data capture mechanisms such as DPDK and OVS in order to deliver information for services running on any type of infrastructure (physical, virtualized and hybrid).

EXAMPLE OF METADATA AVAILABLE FOR SERVICE ASSURANCE APPLICATIONS

  • Flow metadata: application ID, jitter, packet loss, application response time, per flow, delay, MOS, timestamp.
  • User metadata: IP address, GTP.imsi, GTP.imei, SIP.caller, SIP.callee, RADIUS.login, DHCP.mac_address.
  • Device metadata: GTP.user_agent.

This information can be stored or streamed in real-time via standard interfaces for use by any third-party Service Assurance application.

BENEFITS

  • The highly granular and timely information provided by the Qosmos NFV Probe enables Service Assurance solution developers to provide visibility and drill down capabilities that reduce resolution time for quality issues.
  • The Qosmos NFV Probe can be deployed on COTS hardware
