Oracle Communication's Session Delivery Manager provides an advanced framework for provisioning, managing, and monitoring session delivery networks. Session Delivery Manager has an advanced architecture, called Service Oriented Architecture (SOA), which provides such features as increased scalability using load balancing across clustered servers, the ability to load Session Delivery Manager Configurations on-demand, and a rich thin-client interface. You can use the enhanced user interface to access such services as Element Manager for configuring Oracle Communications SBCs or Route Manager for configuring LRTs on Oracle Communications SBCs.
Session Delivery Manager also includes a dashboard summary view of key performance indicators for the managed devices and provides three different views into Oracle Communications SBC configuration elements: Default, List, and ACLI.
Element Manager 2.0
Oracle Communications Session Delivery Manager’s Element Manager Application allows for the loading, configuring, and managing of devices, (Net-Net SBC). This release of Oracle Communications Session Delivery Manager can manage the following devices:
- C-Series—The Net-Net 4000 series contains two systems: the Net-Net 4250 and Net-Net 4500. The Net-Net 3000 series contains two systems: the Net-Net 3800 (Sku 3810) and Net-Net 3820.
- D-Series—Also known as the Net-Net 9000 series, it contains one system: the Net-Net 9200.
- E-Series—Also known as the Net-Net 2000 series, it contains one system: the Net-Net 2600.
The Session Delivery Manager Northbound Fault Management allows you to configure destination receivers to receive forwarded traps in either SDM or ITU X.733 standard formats. You can specify selected traps on devices using the ITU X.733 format in the Add/Edit trap receiver dialog. A maximum of 10 trap receivers may be configured at once, regardless of format.
The SDM server receives the alarms from SBCs and forwards them to selected devices.
In this diagram, the SBC sends all traps to the SDM server, which sorts them into events and alarms. Events are the aggregated list of all such messages while alarms record only the current state or latest event. Imagine the SBC first sends a trap indicating the fan is operating at 10% and later sends a trap indicating the fan is operating at 50%. In SDM, the alarms tab will display the trap indicating the fan is operating at 50%, whereas the events tab will display both traps.
New Features / Applications in Session Delivery Networks (SDM) 7.4
Report Manager 2.0
Beginning with SDM 7.4, the Report Manager uses the Oracle BI Publisher to manage and render reports. BI Publisher is a complete reporting solution to author, manage, and deliver reports.
The previous reporting tool in NNC 7.3 has been obsoleted. Unlike its predecessor, BI Publisher allows users to create their own reports and dashboards as well as schedule and print out these reports in the multiple formats. Users can also monitor their system with the canned reports.
If you've been using a previous version of Report Manager, pay close attention to the Installation Guide, especially for the additional options about reporting database migration.
Offline Configuration
Offline configurations are configurations that can be applied to multiple devices, in order to share the same configuration data. An offline configuration is created by duplicating an existing managed device configuration or by selecting a schema from a supported software model.
Data variables allow network administrators to target elements that require device specific information, when duplicating an existing configuration. All data variables must have new values in order to push the configuration to a device.
Device Clustering
A device cluster is a collection of devices sharing the same hardware, software, and configuration. By specifying an offline configuration and adding devices to a device cluster, SEM allows you to synchronize configuration changes across all members of the cluster.
Members a device cluster must share the same software version and device credentials in order to share the same configuration. Device-specific parameters can be targeted as data variables, in order to set different values for each member.
Application Orchestrator
The Oracle Communications Application Orchestrator (AO) manages the virtual network function (VNF) life-cycle and provides a central location for integrating and managing multiple virtualization infrastructure management (VIM) systems.
AO provides a virtualization management framework for provisioning commands to virtual hosts while collecting performance information on actively deployed VM instances.
Elasticity mode enables AO to respond to changes in network capacity requirements by calculating thresholds on key performance indicators. AO automatically provisions virtual devices to meet demand. AO also allows for manual setup and deployment of individual virtual devices.
Example Configuration
VM groups are a logical grouping of VMs that share configuration and scaling thresholds.
An offline configuration template is required in order to configure a VM group. See example below:
VM instances are singular or HA paired VNF deployments assigned to a specific VM group. VM instances cannot deploy unless the device-specific data variables are configured for each instance. The Configure device wizard walks through the steps of configuring device-specific boot parameters and data variables.
