End-to-End Quality of Service

A part of Tektronix' Unified Assurance product suite, Orion provides visibility into the quality of the services that are being provided to all of your customers. Orion applications may be used independently or as a complement to GeoProbe | APM's network-performance focused capabilities. Orion provides significant benefits through the following capabilities:

• End-to-end analysis of correlated media and signaling packets
• Speech quality metrics through the analysis of RTP packets, RTCP packet monitoring and end-of-call quality media information
• Monitoring of individual services per session across all subscriber usage
• User-settable thresholds for the alarming of signaling and media events
• Proactive notification of service problems to network personnel

Proactive and Efficient VoIP Service Management

Orion enables you to perform proactive and efficient management of revenue generating services and applications delivered to your customers. By providing end-to-end performance monitoring of services through the use of KPIs and statistics generated from actual customer traffic, Orion can provide visibility on the quality of service delivered to retail and wholesale customers for IP based voice services.

Orion does this by correlating application, session control and media packets across all monitored interfaces and all protocols within your network.

In your network, a significant number of elements, applications and protocols are involved in delivering IP services to the end user. At any given time, various minor, major and critical alarms are present—revealing situations that may or may not affect the quality of your IP voice services.

In order to effectively manage the quality of IP services quality, you need visibility to whether events at the network layer are causing problems with the service delivered to end-users. Orion’s ability to monitor the service layer allows you to concentrate on issues affecting revenue generating services.

In addition, the actionable path feature facilitates the process of detection and localization of the affected network elements for quick, proactive problem resolution.

Orion provides a comprehensive toolset for IP based service layer management:

• The Operations application provides real-time and historical service performance metrics correlated by node and a guided troubleshooting path for accelerated problem resolution.
• The Management application provides an extensive array of reports including transaction attempts, transaction failures, QoS performance, session performance and service fault reports.
• The Planning application offers OLAP-based trending and analysis capabilities.
