IMS RICH-MEDIA VOICE AND VIDEO SUPPORT

Both the BrixCall active testing and live call performance analysis applications feature full support for IMS-based rich mediaservices, including support for 3GPP rich communications suite (RCS) specifications.IP voice and video media quality is continuously measured by a full set of key real-time transfer protocol (RTP) metrics, includingRTP streams volumes, codec utilization, bandwidth, average and burst packet loss, average and peak jitter, packet discard, andone-way and round-trip latency. Audio media performance is characterized on a per-stream basis using standardized ITU G.107E-model algorithms to produce both R-Factor and MOS scores. Standardized PESQ measurements are also available for activeperformance analysis.Video media performance is supported by identical raw RTP metrics, but also features Brix-patented video quality index (VQI)algorithms to produce a single metric view of video media performance.

ACTIVE PERFORMANCE MONITORING

Deployed in conjunction with Brix BV-110 and/or BV-3100 Active Verifiers, BrixCall active performance monitoring is an integratedcomponent within the BrixWorx central-site software engine the provides direct measurement of VoIP, IMS and video call networkelement performance. Network active tests directly measure underlying signaling and media transport performance, whereasservice active tests directly measure service quality from network to subscriber and from subscriber to network. Features suchas on-demand tests and media loopback tests provide direct methods to troubleshoot VoIP, IMS and video call functions ifperformance degradations are discovered.

LIVE CALL PERFORMANCE MONITORING

Deployed in conjunction with Brix-41xx/42xx series Verifiers, BrixCall live call monitoring is an integrated component within theBrixWorx central-site software engine that closes the visibility gap between expected network performance and actual customerexperience. As a result, network operators can accelerate VoIP, IMS and video calling deployments with confidence, and achievegreater profitability from IP-based services. With BrixCall, providers are able to satisfy their subscribers by delivering high-qualitycustomer care along with a high-quality service.

DASHBOARDS AND HISTORICAL METRICS REPORTING

Even in networks carrying large volumes of wholesale VoIP minutes and subscriber calls, BrixCall enables VoIP and IMSadministrators to monitor the overall health of their service via an at-a-glance dashboard. The BrixCall dashboard presents criticalinformation about the current state of the service, including all performance threshold violations, call disposition, average meanopinion scores (MOS), peak call volume and bandwidth utilization, answer seizure and network efficiency ratios, and call durationinformation.

For finer-grained visibility, a host of configurable live call reports are accessible from the dashboard home page, and can becustomized for a specific time period and filtered by protocol, Codec, monitoring location, DiffServ code point, call duration,VLAN tag and more.

PER-SESSION RICH CALL QUALITY RECORDS

Today’s VoIP/IMS networks are characterized by separate routes for signaling and bearer traffic, as well as multiple signalingprotocol legs and media streams for individual calls. To achieve visibility across an entire call, providers typically deploy BrixVerifiers at multiple locations across their networks, independently measuring each call component and leg. The key challengewhen monitoring live VoIP/IMS traffic from multiple points in a network is learning how to manage and make sense of the largevolume of performance information. BrixCall analyzes and correlates these independently measured views to provide a single,easy-to-understand call quality record (CQR) for each call.Depending upon the user-selected reporting frequency of the Brix Verifiers, BrixCall generates CQRs for both in-progress andcompleted calls. Point-in-time performance information for active calls is often critical for troubleshooting intermittent problemsthat surface only on calls of longer durations or at particular times of the day.

INTEGRATED CALL FAILURE ANALYSIS AND TROUBLESHOOTING

Integrated call failure analysis instantly characterizes the presence and location sources of call routing and setup failures. Callsearch tools can then be launched to pinpoint detailed information, including source and destination numbers, MOS, duration,bandwidth, call setup and routing performance metrics for individual calls. Once offending calls are isolated, CQR records providefull per-call metrics and integrated end-to-end call flow diagrams for easy problem isolation.

PROACTIVE PERFORMANCE ALERTING

Leveraging the capability of the BrixWorx central-site software engine, BrixCall administrators establish and monitor performancethresholds to proactively alert operational staff of call quality degradations, outages or abnormal calling patterns. Thresholds canbe standardized network-wide or customized for individual locations, depending on business requirements.

BRIXWORX UNIFIED PLATFORM

BrixCall active and live performance monitoring applications are integrated members of the BrixWorx correlation and analysisengine. In addition to hosting VoIP, IMS and video calling service assurance applications, the BrixWorx platform hosts a full suiteof synergistic service assurance applications, such as BrixNGN for Ethernet, IP/MPLS and other data service monitoring, andBrixVision for IPTV and VoD monitoring.BrixWorx ensures that all hosted service assurance applications have access to a common set of important functions, such asOpen APIs for easy integration of KPIs and Alerts with third-party OSS systems. Users have easy access to the service status,SLA, problem detection and troubleshooting functions through the all Web-based BrixWorx Operation Center.
