VistaInsight | NFV service assurance

CSPs’ enterprise customers (retail, carrier-to-carrier and 5G slicing) require complete real-time visibility of their business services against the agreed SLAs. VistaInsight hybrid network solutions handle enterprise-specific, complex SLA requirements through proactive SLA management and real-time service performance visibility for each business service. Its real-time view of business services helps to minimize the SLA violations by matching service level objectives to specific network KPIs in real-time.

Since the configuration of the SD-WAN overlay can impact the infrastructure underlay, and the performance of the underlay can impact the overlay performance, VistaInsight correlates the performance of the overlay with the performance of the underlay for an end to end visibility of the SD-WAN service performance. Infovista Open APIs collect information from the inventory and the SD-WAN controller, Service orchestrator or Edge devices over a Kafka bus to assure multi-vendor overlay/underlay correlations in real-time.

As CSPs onboard Virtual Network Functions (VNFs), some key VNF resource utilization KPIs need to be monitored against the allocation. VistaInsight can help to measure, audit and normalize the KPIs associated with multi-vendor VNF capacity, as well as monitor VNF spin-up/down time, availability, and inter-VNF latency and packet loss. This assures performance continuity as the VNFs move from onboarding to operation.

Multiple OSS entities in the CSP ecosystem can cause significant delays in assuring network and service quality, other than increasing the capex and opex. Through multi-source real-time acquisition of data via telemetry, open APIs and data mediation bus, VistaInsight offers a solution for interoperability, thus breaking down the operational silos, offering performance management across the entire network in a single pane of glass.

4G and 5G mobile service providers face complex operations because of multiple Service Assurance systems, RAN performance issues and resource planning. VistaInsight’s sister product, VistaInsight Mobile offers end-to-end 4G/5G performance management with capex optimization/analytics, supporting 4G expansions and 5G rollouts. Custom dashboards lead to configuration / performance / faults for each network element for advanced root-cause analysis. Automation of problem-fixing is embedded in the tool for fast time to resolve with minimal or no human effort.
