Ensemble Service Intelligence (ESI)
Overture Ensemble Service Intelligence (ESI) is the only truly open carrier-class big data collection and analysis solution for network functions virtualization (NFV.)
ESI provides service and network monitoring and unstructured data correlation that offers numerous OSS and automation benefits. It is an essential solution for helping CSPs realize and profit from the NFV promise of agility and elasticity.
ESI bridges the gap between the multi-vendor service, virtual and physical layers as well as IT, cloud, network silos to dynamically correlate data for the needs of individual applications and/or users. ESI provides actionable intelligence that helps communication service providers (CSPs) optimize NFV environments for greatest profitability.
Embedded within the ESI framework is a dynamic correlation engine, which can model unstructured data relationships between virtual and physical network resources and the services they support. ESI uses that model to transform disparate component level statistics and service delivery details into correlated information about the NFV service.
One example of how ESI can benefit the CSP is the collection and analysis of statistical data from virtual services running at various service points in the cloud infrastructure. As services approach SLA limits, ESI follows scaling rules defined by the northbound OSS integration, allowing for service to scale up and relieve operational stress.
Another example is big data collection for statistical analysis. The heart of ESI is a graph database that enables users to define several monitoring points throughout a network for lifecycle management and control. These monitoring points can be used to develop 3D models for deployment scaling and operational growth development. ESI is based on a graph blueprints implementation and interoperability with any graph database solution is automatic.
Raw and aggregated data can also be used to learn how the cloud networking components are performing; how individual VNFs or services are performing; which services are being used; customer usage patterns; and network failure root cause analysis.
ESI harnesses data from different network functions from diverse vendors to address the following types of analytics applications:
• VNF & NFV service lifecycle tracking, performance dashboard, auto-scaling
• Disaster recovery planning
• Capacity management/planning
• Root cause analysis
ESI is an essential enabling tool for market transformation: making NFV real and profitable for CSPs. It is also an essential tool for addressing the mad crush of on-demand and responding in a quick and cost-effective manner to new paradigms like Internet of Things (IoT.)
With cost-effective, quick and reliable service delivery and new automation capabilities end customers will benefit by getting the services they want almost immediately. Changes can be implemented in minutes as opposed to weeks.
As new paradigms like Internet of Things develop, ESI helps CSPs trial and monitor new service and billing options, and track how those services affect the network. This enables cost-effective new service delivery and assists with development of new billing plans for service models yet to be defined. The end customer can benefit from quicker and lower cost service delivery and immediate scale-up or down.
