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, SIP ED137B, RTP, MEGACO, MGCP, H.323, Skinny (SCCP), RANAP (UMTS IuCS), PPP, and GSM A.
GL’s Packet Analyzers 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.
Packet Data Analyzer (PDA) is a real-time IP and VoIP analysis tool in PacketScan™ and MLPPP Analyzer (T1 E1, T3 E3, OC-3 STM-1 / OC-12 STM-4) that non-intrusively captures and monitors live IP, VoIP, and IP based Video traffic.
- Segregates, captures, and collects statistics on VoIP calls.
- Provides graphical presentation of analysis, including ladder diagrams of protocols
- Monitors QoS (quality of service) on voice and video calls
PDA is an outstanding tool for live monitoring of VoIP traffic. It can also monitor, report, analyze, and capture calls for infinite time, limited only by the finite space of your hard disk or network hard drive.
Detailed call statistics such as packet loss, gap, jitter, delay, RTP performance statistics, R-factor & MOS scores, and unparalleled voice band statistics can be monitored simultaneously. Sophisticated filters permit zooming and recording of specific calls of interest. All or filtered traffic can be recorded into a trace file.
Users can listen/record audio and video data of a session VoIP calls in real-time; perform power, frequency, spectral, tone and digit analysis, and video analysis with ease and precision; get an exact picture of QOS (quality of the service) and the technical adherence of the system under test (adherence to the protocols specified by the standardizing authority).
Packet Data Analyzer supports the following three views:
- Summary View (Call Quality Matrix) displays complete summary of VoIP call information in graphical format along with a summary of alerts.
- Detail View (RTP Diagnostic View) displays packet by packet statistics for particular call information in tabular format. This allows the user to have a detail look at the two (or one) RTP sessions that are part of a single call. This distinction assists in any comparisons that are to be made between the two sessions. Here each frame of the selected session is dissected and its contents are displayed in a tabular form for easier viewing and comparisons. Vital aspects from the RTP frame needed for close analysis are included provides in tabular and graphical formats. A host of counters gives the user an instantaneous snapshot of the VoIP traffic on the network.
These interfaces allow users to define parameters such as E-Model based MOS and R-Factor score, VQmon settings, & Dynamic Payload Mapping. It also supports real-time digit capturing like DTMF, MF and user-defined digits/tones.
- Registration Summary View displays statistics and status of the SIP registration process, an active registration graph, and registration trace graph of each SIP registration.
