Sentinel 4.0

Monitoring and control of multi-layer operational networks and services

The challenge power utilities face in implementing their operational communication network is how to manage an evolving, multi-technology, multi-vendor telecom infrastructure to deliver services with a guaranteed level of quality for multiple groups of users with different service requirements.

Our Sentinel 4.0 management solution aggregates, correlates, and visualizes telecom data from multiple network layers and technologies into user-oriented views, facilitating operational decisions to restore services, notify users of potential service impacts, and meet KPIs and performance metrics. The result? Better efficiency and productivity; enhanced monitoring of mission-critical communication services and infrastructure; and reduced downtime and maintenance costs.

Core Capabilities

Integrated management of complex multi-vendor networks
Prompt fault localization
End-to-end availability monitoring and measurement
Rapid deployment irrespective of legacy technologies

Differentiating Features

Improved functions, scale, and cost for grid operational communication networks
Fault, performance, and incident management in a single integrated platform
User dashboards, impact notifications, and service statistics

Improved Outcomes

Enhanced operator awareness and proactive management
Documented and formal communication service delivery
Structured framework for network information
Comprehensive cybersecurity solutions

Sentinel diagram 1

Sentinel 4.0 is a vendor-agnostic management platform designed to fulfill the requirements of power utilities’ operational communications.

Multi-vendor and multi-technology – Allows for flexible construction of the network with best-suited building blocks without committing to any specific single vendor.
Easy to deploy, operate, and maintain – Provides a powerful solution for monitoring, supervising, and reporting on devices and services at the grid scale, restraining to features that are relevant for the operational network, hence reducing cost, complexity, and learning effort.
Fully under the utility’s control – Resides entirely inside the power utility’s governance and security perimeter.
Enhanced operator awareness – For fast fault detection and localization, proactive management (detect anomalies before users), reduced downtime, efficient usage of work force, and reduction of maintenance costs.
Enhanced user awareness – For the proper operation of mission-critical applications, prompt information on services impacted by network anomalies, and assurance that service requirements are constantly fulfilled.
Single source for network information – Sentinel 4.0 inventory provides a coherent and unique source of information common to functions such as network operation, maintenance, transformation projects, planning, etc., facilitating exchanges between network management actors and stakeholders.

Sentinel 4.0 Management Framework Operational Principles

Sentinel 4.0 collects alarms and events as well as service performance data from devices and dedicated managers, associates contextual network and quality constraint information to the real-time collected data, and consequently generates operation and maintenance information for the communication service provider and quality of service information for the service users.
