With most carriers rolling out multi-services, including voice, video, fax, and data transported via packet networks, there is need for constant testing and monitoring of Quality of Service (QoS) and Network Performance of Next Generation Networks (NGN).
GL's PacketScan™ - an All-IP Network Monitoring software offers powerful features to capture and monitor live signaling and traffic over IP (version 4 and 6). It captures, segregates, monitors and collects statistics on all IP calls. Almost all VoIP and Wireless protocols over IP transport layer, as listed below, can be captured and decoded for troubleshooting network problems.
Some of the important applications of PacketScan™ are:
Thousands of calls can be monitored in real-time including detailed analysis of selected voice band streams. Applications include testing of IP phones,
Gateways, IP Routers and Switches, and Proxies.
Users can listen/record audio and video data of a session 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).
Its ability to monitor / record audio and video data of a session to files (in QuickTime *.qt format), allows user to perform
powerful video analysis. The captured VoIP calls can play-back video using 3rd party VLC Viewer application. The application is
capable of displaying Video Statistics such as Source/Destination Video Channels, Media Type, SSRC, Total Packet Counts, Missing Packets, Duplicate Packets
and Out of sequence Packets, Average Delay/Gap, Video Frame Count, Frame rate, Media Delivery Index (MDI- (Delay Factor: Media Loss Rate)), and Average
MDI for each video session.
PacketScan™ with Video QoS capability addresses customers long felt need of Video Call Quality in IP networks.
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.
PacketScan™ supports Packet Data Analysis (PDA) module allowing users to report every call in detail. PDA processes the captured packets, identifies, and segregates calls based on signaling and traffic parameters. Supported protocols include SIP, MEGACO, MGCP, H.323, SCCP, RANAP (UMTS IuCS), and GSM A.
PacketScan™ further supports the following three views in Traffic Analysis or Packet Data Analysis (PDA) window:
- Summary View (Call Quality Matrix) displays complete summary of 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
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.
What sets apart PacketScan™ is its ability to collect vital statistics about calls for theoretically infinite time. The ability of
PacketScan™ to capture data is limited only by the hard disk capacity of the PC. It can work with
NetSurveyorWeb™, a central monitoring system for a comprehensive view of network performance.
It features rich graphics, ladder diagrams and CDRs (Call Detail Records).

Call Detail Records & Statistics View
- Call detail records (CDR) isolates call specific information i.e. status of each call (i.e. active/completed), duration of completed call, Source & Destination addresses, Call type, Release cause, Conference ID, Call identifier, and more. Calls and sessions are classified as active, completed or failed giving the user an idea about the calls and its status in the network. Additionally, users are provided with the option to search for a particular call detail record from the captured traces
- Statistics View displays statistics based on frame count, byte count, frames/sec, bytes/sec etc for the entire capture data. Statistics can be obtained for any fields or parameters in the protocol to study the performance and trend in the VoIP network.
Real-time and Offline Analysis
Users can capture and analyze packets through real-time analysis or analyze the recorded data in offline mode. All captured or filtered traffic can be recorded
into a trace file. The recorded trace file can be used for offline analysis or exported to a comma-delimited file, or ASCII file. The real-time analysis requires an
Ethernet cards to be specified on which data is received.

Filtering and Search
Users can capture and analyze packets using real-time analyzer and record all or filtered traffic into a trace file. The recorded trace file can then be analyzed
offline and exported to ASCII file, or printed. Filtering and search capabilities add a powerful dimension to the SIP analyzer. These features isolate required
frames from original frames in real-time/offline. It allows real-time filtering based on parameters set in Data Link layer, MAC layer, IP, TCP/UDP and more. The
offline filter allows filtering based on Frame Number, Time, Length, Message Types, and so on. Similarly, search capability helps user to search for a particular
frame based on specific search criteria.

Enhanced Trace Saving Options
Users can control the captured trace files by saving the trace using different conventions such as trace files with user-defined prefixes, trace file with
date-time prefixes, and slider control to indicate the total number of files, file size, frame count, or time limit. This feature also allows the captured frames to be
saved into a trace file based on the filtering criteria set using display filter feature.
Configuring INI Files
PacketScan™ allows users to to customize protocol decoding options as per the requirements. Users can edit the PacketScanProt.ini files to customize the decoding options.
Save/Load All Configuration Settings
Protocol configuration window provides a consolidated interface for all GUI and protocol settings required in the analyzer.
For repeated testing, all the configuration settings done in any of these options can be saved to a file, loaded from a configuration file, or user may just
revert to the default values using the default option.
This also includes automatically connecting to a remote database for NetSurveyorWeb™ applications. This can be useful in remote monitoring
applications where a laptop can be setup and configured for plug-n-play testing.

As a Single Point Packet over IP CDR Analysis System
To provide a more comprehensive method for analyzing pinpointing quality problems, PacketScan™ has been enhanced to work with GL’s VoiceBand
Analyzer (VBA) and Call Data Records (CDR) applications to trigger on all calls and generate comprehensive call detail reports along with audio files.
- The audio files are processed using VBA to measure actual analog voice parameters such as Active Speech Level (ASL), Noise Level, Activity Factor (AF), and
- CDR application uses the per call data from PacketScan™ and VBA analytics to provide useful call detail records for further analysis using Excel®. The
working is depicted in the below picture.
- The generated CSV reports from CDR application are analyzed using built in tools included with Excel. The records can be filtered using Advanced Filter in
Excel® tool based on signaling, or various measurements to generate reports of “calls of interest”. The voice files of these calls can be either downloaded, or
played back using Goldwave® or any audio program.
