Ensemble Network Controller

The Ensemble Network Controller (ENC) is a service aware network controller and management system. ENC is equipped with a powerful web-based graphical user interface as well as open northbound APIs. As such, ENC supports three deployment models

  • A stand-alone service management system
  • A network controller and service management system integrated into higher level management and provisioning systems
  • A complete NFV management and orchestration (MANO) system when integrated with Ensemble Service Orchestrator and cloud controller

With native support for all Overture network elements, ENC is extensible to support third-party network elements. ENC automates device detection, fault management and performance monitoring. By presenting a complete network picture, CSPs can focus on adding new services and virtualized network functions without compromising existing network operations.

Network Management
ENC brings the entire network into a single, simplified view. Every layer, service, network element and connection is managed from graphical, template-driven interfaces that present a deep and complete picture. APIs connect northbound interfaces so no device or service is left out. Users can setup automation rules based on specific criteria including software updates, performance monitoring and fault management to reduce errors and streamline maintenance. A complete, accurate view of the network frees operators up to focus on provisioning, service creation and service orchestration.

Service Creation and Management
CSPs can accelerate service creation when they know where – and what – services are efficiently running on the network. ENC allows network operators to poll all elements, then correlate each device’s location with the services it’s running. The result is an unmatched level of service awareness. With resources properly identified, CSP can create and activate new services quickly and without interruption across their complex, multi-vendor landscape. Network operators can define E-line or E-LAN services on single network devices or across multiple locations through enhanced MEF templates. Services can be created in minutes, not in weeks or months.

Performance Monitoring
ENC presents a complete view into the network health by gathering interface-level performance data at regular intervals. Service level performance is assured through a comprehensive set of Ethernet service-level SLA management tools, leveraging CE2.0 constructs. Archived on a server for easy access, users can graphically see statistics versus time to correlate anomalies or errors to customer issues. ENC also makes it easy to perform service activation testing to ensure that the network is provisioned to support the committed SLA.

Fault Management
ENC elevates network management by reporting faults from each device or service throughout the network. Customized alarm filters and escalation policies help your people work smarter and faster, not harder. And, this helps CSPs intercept failures prior to customer calls about a service outage. ENC can forward traps from network devices to northbound surveillance systems and filter unwanted tracks based on a fault source or persistence time. All fault events and alarms, including filtered child views, are documented in customizable reports. The ENC simplifies operations and reduces upstream monitoring costs.

Feature Benefit
Servcie-level Configuration and Visibility From a single pane of glass, the CSP can create, activeate and assure CE2.0 services. Service and network performance and faults can be correlated for complete visility into customer experience.
Open northbound APIs Easily integrate into higher level managment, OSS and BSS systems and third-party networks elements.
Graphical interface
ENS's question-and-answer format feeds extrememly simple graphical interfaces. Users can click a map to see device alarms, chassis configuration or to telnet into local device OS. ENC template reduce human errors and improper configuration changes to servcies and specific elements.
Complete device detection
ENC performs background scans across the entire network automatically detecting and adding new devices to the inventory using SNMP. It controls discovery on devices or entire subnets based on flexible user criteria and domain grouping at specifically defined intervals. ENC discovers chassis, cards and even services, regardless of the method used to provision them to a device. All inventory views can be shared, via post analysis tools, as CSV files.
Configuration managment ENC provides tools that capture every alert from every network device when configuration changes are made. This is particularly important when so many services are running at the metro service edge. ENC allows users to automatically save a date-stamped configuration of each network device to a specific FTP server. If the device fails, users can quickly identify needed steps to get it up and running. This greatly minimizes replacing the device and restoring configuration.
Network KPIs
ENC’s easy-to-read network summaries show an “at-a-glance” view of network availability
and fault resolution statistics. Users can set thresholds for alerts based on user-defined
criteria and access reports that show fault history by severity, type and those that generate the
highest number of alarms.
