Detailed Packet Analysis

Packet Data Analysis (PDA) is an outstanding tool for live monitoring of signaling and traffic over IP. Packet Data Analysis (PDA) is distributed with GL’s Packet Analyzers, allowing users to monitor live IP networks including capture, analysis, and reporting of every call in detail. Supported protocols include SIP, MEGACO, MGCP, H.323, SCCP, RANAP (UMTS IuCS), GSM A, CAMEL, BICC, ISUP, MAP, Gb, and GTP. It can capture IP packets over different transmission lines, including IP, T1, E1, T3, E3, and OC-3 STM-1 / OC-12 STM-4. PDA then processes the captured packets, identifies, and segregates calls based on signaling and traffic parameters.

PacketScan™ provides in-depth real-time and post-process data investigation. The PDA view assists in any comparisons that are to be made between the two RTP sessions. Packet Data Analysis (PDA) view displays call information in graphical format (Traffic Analyzer Call Quality Matrix- Summary View) as well as in tabular format (RTP Diagnostic - Detail View).

Graphs

Graphs are provided for key statistics for network monitoring and troubleshooting. Graphs available include – Active Calls, Average Jitter, E-Model MOS/R-Factor/Packets Discarded, RTP Packets Summary, ladder diagram for T.38 based fax calls and call signaling, Gap, Jitter, Gap/Jitter Distribution, Wave and Spectral Display for media stream analysis, VoIP calls and more.

This feature requires activating the Export Terminated Calls option from PDA prior to live capturing. This structured text file can be imported into Excel® using a custom add-in (Excel-Dashboard-Tool-IP.xlsm) to generate different chart types such as call volumes, call duration, call failure causes, CMOS, LMOS, packet loss and more.

For more details, refer CDR Analysis Tools webpage.

Call Summary details could also be saved for a particular call and this will be saved as a *.rtf file. This allows the users to get data from real-time traffic locations for detailed analysis of a flawed call.

Save Call

Video Quality Metrics

Support Video Statistics such as Source/Destination Video Channels, Media Type, SSRC, Average Delay/Gap, Packet Counts, Codec Type, Missing Packets, Delay, Gap, Video Frame Count, Out Of Sequence count, Duplicate Packets count, Media Delivery Index (MDI- (Delay Factor : Media Loss Rate)), and Frame Rate are provided for each video session. PacketScan™ with Voice, Data, and Video QoS capability addresses customers long felt need of call quality analysis in IP networks.

Media Delivery Index (MDI) measurement is used as a diagnostic tool or as a quality indicator for monitoring a network intended to deliver applications such as streaming media, MPEG video, Voice over IP, or other information sensitive to arrival time and packet loss. Media Delivery Index (MDI) can be used to monitor both the quality of a delivered video stream and to show system margin for IPTV systems by giving an accurate measurement of jitter and delay at network level (Internet Protocol, IP), which are the real causes for quality loss. The Media Delivery Index is typically shown as two numbers separated by a colon the Delay Factor (DF) and the Media Loss Rate (MLR).
