Managing Complex Multimedia Sessions, more than just raising alarms (SDM)
by Eva Pavon

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.

Multimedia Sessions

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.

Multimedia Sessions

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.

Multimedia Sessions

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:

Multimedia Sessions

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.

Resolving Enterprise Routing & Dialing Plan complexity with Enterprise Communications Broker (ECB)
By Gabriel Ostolaza

If you rely on PBXs to determine a Dial Plan and a routing plan, then as PBXs are added to the network, not only do you need to program the new PBXs, but a significant programming effort is also required on all the existing systems. By sending all calls to an Enterprise Communications Broker (ECB) for centralized processing, the addition of new PBXs requires only a simple configuration for that new PBX and a small modification to the existing ECB configuration.

In addition, added PBXs may be of different manufacture and require new skills and will further complicate the task.

It doesn’t matter whether the new PBXs are geographically local or remote.

Here is a challenge too often presented. To accomplish full, unblocked, communication between disparate networks, a mesh system seems the only answer. Such a mesh will expand on an N-squared algorithm leading to a completely unmanageably complex network. This type of network is unreliable, has many points of failure, is difficult to troubleshoot and difficult to scale.

Figure 1

Different locations within the same enterprise, such as Corporate HQ, branch office, remote office, regional HQ, and so on, may all have access to the enterprise network, trunks and private lines. However, each may have different Dial Plans – some use 4-digit extensions, others may use 5-digit extensions, or more. This is often governed by the vendor mix used in the different locations. It is particularly noticeable when one company acquires another and wishes to integrate the two companies’ telephone system. Some locations may use exactly the same scheme including the same number range, so that dialing 1234 in one location may wake up the folks in the cafeteria, while dialing 1234 in another location may call the boss.

When an employee travels from one location to another he/she must remember to use the dialing plan of the current location and a call back to his/her office usually ends up being a call on the public system rather than using the enterprise facilities.

What if a traveling employee could simply dial the extension of her primary location as if at his/her own desk? A smart telephone system would know that the employee wanted to make a call to another corporate location, rather than to a local extension.

This is called “Dialing Plan Management” and is a feature of the Oracle Enterprise Communications Broker (ECB).

Figure 2

Here is a para-typical ECB network configuration. In this network, an enterprise uses a variety of telephony equipment and services. The vendor equipment could be geographically dispersed world-wide, but are all connected to the same enterprise network. The enterprise telephony services and applications could be central or similarly dispersed, but shared by the whole enterprise.

Each vendor and/or location could use different Dial Plans, thus making calls between them difficult to avoid using external telephony services. This makes such calls expensive and vulnerable to security concerns.

To facilitate Dial Plan management and session routing, the ECB would be placed at some central, or core, location within the network. It is likely that it would have a close or direct link to the gateway devices such as an SBC if one is employed.

Function:

  • Centralizes enterprise-wide Dial Plan and session routing
  • Provides SIP registrar function for Bring Your Own Device (BYOD) users
  • Provides session-aware layer for application enablement
  • Provides policy control and enforcement
  • Handles SIP traffic only – Not media

Benefits:

  • Streamlines architecture
  • Simplifies provisioning
  • Supports multivendor communications environment
  • Extends to new applications and services
Figure 3

Interface Layout

The ECB uses a purpose built GUI as its primary configuration and administration access. The GUI is not an “Add-on”, rather it is designed to be the primary access to the system. As a result, the GUI is well-designed and it provides the user an intuitive view into the system that makes configuration, provisioning, monitoring and troubleshooting easy.

Analyze traffic and diagnose issues in complex Voice networks in real time with a simple click
By Gabriel Ostolaza

Acme Packet’s Palladion Solution, rebranded Oracle Session Monitor, enables SIP/IMS network operators to monitor the service and network and detect and solve problems related to SIP and other signaling protocols used in Voice over IP (VoIP) networks.
The Oracle Session Monitor software suite contains several products that address unique challenges of various networking customers, and allows for individual licensing of the required functionality. These are:

  • Communications Operations Monitor (COM): It includes the Oracle Session Monitor Voice & Video Operations (VVO) and Oracle Session Monitor Customer Experience & Troubleshooting (CET) product. It comes with a range of features for pro-active monitoring of the network. It also provides advanced troubleshooting, customer support and customer experience capabilities. The work flow is incident oriented and allows one to drill down from higher level symptoms into the full details of network protocols.
  • Fraud Detection & Prevention (FDP): The Oracle Session Monitor Fraud Detection & Prevention product provides functionality enabling operators to not only detect toll fraud activities on the network but also to actively stop such attacks. This is a separate module.
  • Mediation Engine Connector (MEC): It provides scalability and global network visibility Binding multiple ME’s.
  • Control Plane Monitor (CPM): Diameter analyzer. It provides support for non-call-related traffic.

Interface layout
Oracle Session Monitor´s web page has four main areas:

  • Administrator area: on the top right corner, shows user logged in, a signed out option, general help, access to the administration menu (settings) and setup menu (setup).
  • Main menu: on the left has three areas for the different functions offered by Oracle Session Monitor. Voice and video Operation (Operations) and Customer Experience and Troubleshooting  (Customer) group functions that are activated when the Communications Operations Monitor (COM) licence is installed.
  • Main display: is the main user working area where all information is displayed and interaction with panels and tables implemented.

With the help of this solution the Network Operator can do things like analyze the Quality of a recent call, analyze an issue in real time, get a Call Diagram, print the detail of every message involved in the call or even issue a PDF report with all the information related to the call to show the end-user they are working to resolve the problem.
