ElementCenter Feature List




  • Data Models shared with devices to maintain accurate and consistent common object schema.
  • Built in processors for SNMP MIBs and NETCONF YANG models.
  • Enhancement model allows tailoring the device model for management without over-writing it.
  • These models drive the systems that provide a number of value-add services, such as code-generation, automatic validation and auto-UI creation.
  • System can accommodate different versions of each device model, to enable multi-version device management.
  • New models can be introduced in an installed system, without requiring a recompile or upgrade. All relevant artifacts are automatically re-generated at system start up.
  • Supplemental models enhance the data models to support model driven Configuration GUI, Database support, Online help, Device Communications and Service APIs.



  • ElementCenter is designed as a set of modules that interface to one another via well-defined APIs.
  • Adding functionality (either to the core system) or to a customizable product is as simple as adding one or more modules.
  • A Device module provides the means to manage and communicate with a specific type of device.
  • An Application (or Service) module provides functionality to the system that allows it to span multiple devices or enhance the system’s behavior by extending the core .
  • Any Module corresponds to a bundle which is composed of models (which provide the metadata), code (which contains the business logic) and resources (such as icons, web pages and strings).


High Availability

  • ElementCenter processes are monitored by a watchdog to  ensure resilience to process termination.
  • Runs as native platform service that automatically restarts upon system startup.
  • Multiple systems can be installed in an Active-Standby configuration with automatic fail-over and fail-back.
  • Use of shared IP address ensures consistent external access to system.
  • HA-aware GUI rides through fail-overs without user interruptions.



  • Messaging infrastructure for internal components and module.
  • Clients can subscribe by message type, action and/or object type
  • Decouples components facilitating modular, plug-and-play construction.



  • System comes bundled with PostgreSQL, providing performant and reliable database functionality.
  • Can be tailored to support other Relational Databases using simple plug-in mechanism.
  • Sample plug-ins for other databases (SQL Server, MariaDB) provided.
  • Uses Hibernate (and JDBC)  for persisting Java objects.
  • No database code needs to be written – all artifacts required for Hibernate are automatically generated based upon the models.
  • System provides a set of libraries (including a canonical Query API) that allows any code in the system to quickly and effectively access the database.
  • System provides a backup/restore utility that can be used for disaster recovery (or in multi-server configurations)



  • System provides support for licensing on on a per-installation basis.
  • Licenses can be tied to hardware aspects of the system so that they are not transferable between systems..
  • Specific features can be licensed individually (i.e. features can be turned on or off based upon the license).
  • A license can control resource access/scale – e.g. it can restrict the maximum number of concurrent users.
  • Public-private keys and encryption are used for license management, so as to maintain high level of security.
  • Licenses can be timed to expire, with every feature having a post-expiration value, so that the system can run in a degraded state, if necessary.





  • Built-in rich EMS security model with user/group management.
  • Permissions can be assigned based upon devices, actions or configuration object type.
  • Security groups can configured for permissions across collections of devices.
  • Permissions can be dynamically introduced into the system by modifying the XML Service models.
  • System provides integration with external LDAP and RADIUS AAA servers.



  • All relevant user-initiated operations are audited by the system.
  • Operations are audited consistently, regardless of how they are initiated – via the GUI or though the north-bound interfaces.
  • Every audit record contains detailed information information – such as the operation, the user, source machine they are logging in from, time to execute and success status.
  • The set of auditable operations can be controlled using meta-data in the service model.

  • Application modules can work across multiple devices of different types to provide end-to-end functionality, such as service-level orchestration and provisioning.
  • Application Modules supply modeling, services and permissions in addition to business logic.
  • Built-in support for global transactions allows application modules to perform atomic transactional operations across multiple entities within the system.
  • Application Modules have access to all internal components such as the alarm system, messaging system, configuration  framework and all device controllers.
