Overview
PacketScan™ is a powerful tool that captures live IP traffic, and segregates into SIP, H323, Megaco, or MGCP
type calls. It also collects numerous statistics about the calls. Hundreds 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. It allows the user visibility into VoIP traffic and signaling with great depth.
PacketScanWeb™ is a network monitoring extension of PacketScan, wherein multiple PacketScan’s monitor
and provide statistics to a central database. Users can observe (in real-time) the monitored packet traffic using a simple
web based interface. A real-time demonstration is available for clarifying the features available – see diagram below.
Lab System Setup
Components of GL's PacketScanWeb Demo System
GL's PacketScanWeb™ demo system has a three tier architecture. Each PacketScan™ probe in layer 1
captures and transmits measurements and statistics to a single central database located at the Data Layer. This second
layer provides a means for storing the captured data. The last layer is the Data Access Layer (Application Server) where
the data presentation logic is contained. Each of these components is briefly explained below.
Data Layer
An Oracle database (user specified) is used to store the measurement results along with all pertinent data associated
with the packet capture (call ID, direction, duration and so on). This provides a very flexible and expandable architecture
for data storage and data access. The database is accessed in real-time over the web using an application server or
queried by customer applications.
A listener application is co-hosted with the database server running on the Data Layer. It collects the data posted by
the probes and then updates the database using the collected data.
Application Server
The PacketScanWeb™ provides an application server for accessing the call information & measurements along
with the additional analytical measurements including MOS, Delay, Jitter, and so on. The results are queried over the
internet using any browser-capable device such as desktops, table PCs or PDAs. The application server is capable of
serving the data in real-time or providing historic data based on customer selected filters.
Using the Application Server
Using any browser-capable-device, you can access the results from anywhere in the world. When you point your
browser to the Application Server URL, the following page will be displayed.
Real-time Data
This view simply displays details of all calls in database captured by various probes. The calls on various probes are
displayed with Traffic Summary ID column sorted in ascending order. The view provides various statistics such as , Probe
Name, Calling Number, Called Number, Start Time, Call Duration, Session Request Delay (ms), Session Disconnect
Delay (ms), Originating IP Address, and Destination IP Address.

Call Detail Records
The Call detail is depicted by message sequence which gives ladder diagram of the call flow between the Called and
the Calling numbers.
The Frame Summary detail of any calling number is provided in the following columns - TIMESTAMP, SCRIPADDR,
DSTIPADDR, SCRUDPPORT, DSTUDPPORT, SCRTCPPORT, DSTTCPPORT, SIPMETHOD, SIPFROM, SIPTO, SIPCALLID, &
SIPCSEQ.

Records per page / query
Users can customize the required number of records to be viewed per query and per page. Less number of records
per query will result in faster system response. The web view of results can be automatically refreshed every 1 to 20
seconds of interval.

Record Navigation
Users can navigate to any set of records in the database using the record index. The first and last index of the
records available in the database will be displayed. Enter any record number between the first and last index on the
text box provided. A table beginning with the record index specified will be presented.

Filtered Data
Filtered Data view will provide different filters by which the data records could be viewed. When this view is selected
for a given table, the date and time of the first and last records in the database will be displayed.
Specify the Start Date/Time and the End Date/Time. Keep in mind that the End Date/Time should be after the Start
Date/Time. The PacketScanWeb™ will query the database based on the user-specified time period. A table
beginning with the first record with specified date-time will be presented.
Currently a Customized filter is set as default view. If the customized filter is turned OFF, Date-Time filter could be
developed based on customer requirements view.

Custom Filter
The Custom Filter tab provides options to
- filter call records based on filter parameters such as Probe name, Calling/Called Number, IP Address , and so on
- create new filter profiles
- edit & update already existing custom filter profiles
Screen Shot of Custom Filter View
It allows creating various groups and set filter criteria accordingly. Various Filter Selection Parameters supported are -
Probe Name, Calling Number, Origination IP Address, Called Number, Destination IP Address, Call Success, Start Time,
Duration, Failure Cause, Session Request Delay, Session Disconnect Delay, Payload, Missing Packet Percentage, Duplicate
Packet Percentage, Reordered Packet Percentage, Packets Discarded Percentage, MOS, R-Factor, Average Jitter.
Graphs & Reports
Reports view provides an overall summary of the captured packet traffic over the entire network with the help of
useful graphs such as Call Volume Display, Average Mean Opinion Score (MOS) Display, Call Completion Ratio, Call
Failure Cause, Session Request Delay (SRD), Failed Calls Display, Calls Answered Display, and Average Paid Minutes
Display.
Screen Shot of Graphs and Reports
In the Reports screen, select the required report to be displayed from the Reports Selection drop-down menu. A list
of monthly Reports for various types will be displayed.
