Data Variables

Data variables (DVs) are used in offline configurations to allow network administrators to target elements that require device-specific information. All data variables must have new values to push the configuration to a device. An offline configuration requires DVs that have different values for each device that the template is assigned to support. This allows the template to be finely adjusted to the specific needs of a device and continue to provide a common baseline configuration for many devices. The template editor allows you to apply data variables to any element attribute that the offline configuration supports. A derived value can be specified when the DV that you are configuring shares the same value as another DV (dependency).

Device

A device is the atomic object that cannot be sub-divided and represents the component that does the required work. The element manager supports a network function (NF), but also manages the devices the NF contains. The following illustration shows device groups and their associated NF devices.

Device groups are arranged in a hierarchical structure. The top level group is New England. A sub-level group is Boston. In this sub-level group there is a network function. Within the network function folder, there is a device cluster folder. In this folder there can be several high-level device folders in the device cluster folder. In the device folder there is a device group folder that contains the actual device or devices. If there is more than one device in this folder it would be a high-availability pair.

Device cluster

A network function (NF) device cluster containing one or more groups that contain a device, a device cluster, or a high availability (HA) pair can be provisioned by using an offline configuration. An offline configuration template is used to efficiently target multiple individual devices (with the same software version and platform) so that you can quickly change their parameters with specific values.

Device group

A device group can contain or group NFs and devices.

Note:

Device groups can have polices applied which extend the device group characteristics, such as a cluster group.

Element Manager

The Oracle Communications Session Element Manager (SEM) provides alarm, configuration, fault, loading and provisioning capabilities for devices, performance management for infrastructure elements, and security capabilities.

Geo-redundant group

A geo-redundant group has active and standby devices that are not co-located.

Network Element

A network element is a manageable logical entity uniting one or more physical devices.

Network Function

An NF can be composed of device groups and devices. An NF can be simple or complex. A simple NF can be a standalone device, high-availability (HA) pair or device cluster. A complex NF can consist of device groups that further define topological constructs and complex structures for device containment.

Offline Configuration

A common, top-level offline configuration template can be used to provision network function (NF) device cluster containing one or more groups that contain a device or a device high availability (HA) pair. An offline configuration can be created by making a copy of an existing configuration, packaged configuration, managed device configuration, or by selecting a schema from a supported software model.
