Through a simple and intuitive front page, CSA presents a comprehensive high-level overview of health of applications on your network. From that framework, you can drill down to gain access to more detailed information. As an example, you can display all the activity for HTTP application, then drill down to see activities on each server, and further down to the server flow to observe the actual media content of the flow. This unparalleled level of control and visibility speeds time to application problem resolution and minimize overall network downtime.

Time-based analysis to identify problems quickly
Analyzing large capture files can be difficult because there is just too much information to sort through. CSA provides a time-based analysis of capture files providing detailed statistics and trending information. You can drill down in time to look at adjacent events during the time of interest. For video and voice traffic running SIP or H.323, the analysis engine can classify the video and voice RTP streams based on their quality score, MOS or VQFactor. It will provide detailed statistics of the SIP or H.323 call status and quality of calls. You can select one or more of the RTP streams to be extracted for detailed analysis or replay. Additional analysis is available for HTTP, listing tables clients by server or vice-versa along with specific URLs accessed and error codes. With this analysis, users can identify the problems quickly, without drilling into packet decodes.

The rapid development and deployment of broadband networks implementing telephone, video streaming, and conventional data communications over common IP infrastructure presents immediate real-time challenges for service providers. ClearSight Analyzer provides powerful real-time and post analysis of Triple-Play networks and applications.
ClearSight Analyzer Triple-Play Applications
- VoIP network troubleshooting
- VoIP pre-deployment testing
- Service level measurement and monitoring for IP telephony and video streaming services
- Network baselining for network capacity planning and future investment
Understanding the usage of each application at a glance - Triple-Play usage report
The Triple-Play usage report gives a graphic view of the usage of IP phone (telephony), video streaming (entertainment), and data applications. A user can display the trend of the application distribution for a specified period of time.
ClearSight Analyzer is an easy to use analyzer for realtime or post-capture VoIP and voice quality assessment.
- ClearSight Analyzer generates QoS report for a VoIP call simply by selecting the desired call and clicking the [Report] tab.
- The QoS report includes analysis of voice quality parameters (including packet loss, jitter, R-value, and MOS) stated as VQFactor™ and MDI for a video stream.
ClearSight Analyzer can recreate audio and video content from flows either during real-time monitoring or from a trace-file. In addition Exchange EMAIL, Fax over IP, Instant Messages and HTTP-base web pages can also be reconstructed. This is very valuable as proof of compliance violation or visualization of multimedia quality.

ClearSight Analyzer supports not just simple address and protocol filters, but also filters based on application commands, IP subnets, data patterns, and other criteria.
Complex conditions can be specified with ease by freely adding and combining filter conditions using AND, OR, and NOT operators while viewing the setting panel. Once specified, a filter definition can be saved with an assigned name, and then reused at a later time for capture or trace file display.
Filtering condition can be used for packet capture, packet extraction as well as display filter during packet analysis.
The ClearSight Analyzer's ladder views (also known as application bounce chart) reveal conversations between client and server(s) in the application command language without having to decode packets manually. It provides an extremely powerful way to understand protocol interactions between various network elements. CSA supports most of the commonly used capture file format. It can take in packets captured from up to four locations of the network and merge them to provide a multi-segment ladder chart. This allows timing issue to be isolated quickly by segment for root cause analysis. Combined with the rich power decode feature of CSA, it gives network engineer and application analyst the tools to ends finger pointing.
The CSA-1045 adds three powerful features to the CSA-1000: History Reporter, Packet Generator, and Multicast Visualization.
Historic Reporter
CSA provides large inventory of standard reports in charts and tables format showing statistics and performance for network traffic, servers, and applications. CSA generates reports from real-time data or trace files. It generates QoS reports for voice and video traffic, showing quantities such as jitter, latency, packet loss, MOS, J-MOS, R-value, and video quality factor. Elements of these reports can be easily combined to produce custom reports.
- The report can be customized as required.
- The report can be saved in html, pdf, or rtf format using the export function.
- Trending data can be experted to CSV file for further analysis or report generation with 3rd party applications

Packet Generator
A versatile traffic generator allows you to perform network load testing and traffic reproduction testing. Two modes are supported: packet mode (in which a specified packet is sent repeatedly) or in buffer mode (in which traffic from one or more trace files are replayed on the network).
Multicast Visualization
The CSA has ability to analyze multicast traffic for IPTV found in many service providers today. It automatically groups Multicast stream and show server/clients for each multicast stream.
It provide Channel Zapping Analysis that reviews IPTV Channel Change Latency (time from channel change command arrived to current channel signal cease) , Channel Gap (time with no channel signal feed when changing channel) and Channel Overlap (noisy screen when changing channel). It also shows Client based visualization of multicast streams, showing how a user zaps several TV channels.
