Hardening the ONAP framework isn’t easy – assurance analytics pave the way.

ONAP supplies an extensible framework for orchestrating next-generation offerings. But ONAP alone is not a solution. Through integrated end-to-end assurance, Service Providers can reliably launch innovative services while providing outstanding QoE.

DCAE

Data Collection, Analytics and Events centrally consolidates telemetry. SONAR4 scales your capability out to the network edge:

Semi-autonomous edge for localized issues
Ultra low-latency responsiveness
Massive reduction in telemetry backhaul

VES and DMaaP

VNF Event Stream and Data Movement as a Platform represent the basic ‘plumbing’ within ONAP. SONAR4 pre-processes edge telemetry to reduce workload:

Improved scalability and reduced workload.
Filtered northbound alarms are VES-formatted.

Holmes

Drools-based root-cause analysis module works in conjunction with DCAE, Holmes provides basic alarm correlation for managed resources within A&AI. SONAR4 dramatically augments this capability by:

Pre-handling most edge use cases, allowing HOLMES to perform higher level correlation.
SONAR4 can include non-ONAP data in decisions
Correlation not limited to network connectivity.

TCA

ONAP’s Threshold Crossing Analysis supports simple configuration of alarm rules. SONAR4 augments TCA by enabling:

Complex multi-step decision pipelines.
Aggregated and transformed telemetry involved in analysis.

POLICY

ONAP’s policy module is a Drools-based mechanism to trigger closed-loop actions. SONAR4 helps Policy through:

Actionable alerts using AI and correlation algorithms.
Highlights root cause.

A&AI

Active and Available Inventory provides key topology and state information for ONAP. SONAR4 leverages A&AI to deliver a step-function increase in inventory granularity:
