GL Communications Announces Enhanced Traffic Analysis Tool

February 07, 2014

GL Communications, a provider of network testing and analysis tools, announced the launch of Packet Data Analysis (PDA), an enhanced Traffic Analysis Tool for Voice over IP (VoIP).

PDA is an ideal tool for live monitoring of signaling and traffic over IP.  It allows users to monitor live IP networks including capture, analysis, and reporting of every call in detail, said Karthik Ramalingam, manager Product Development of GL.

The PDA features RTP packet statistics and call flow ladders, performance metrics, audio and video analysis, T.38 fax over IP analysis, triggers and actions, and CDR report generation. It also acts as a probe in network monitoring system.

GL Communications supplies test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. These testing tools range from simple PC-based software test tool to all-encompassing hardware units with futuristic expansion capabilities.

These test solutions are designed to cover a wide array of networks – 4G (LTE), 3G, IP, Ethernet, T1, T3, E1, E3, OC-3/STM-1, OC-12/STM-4, and traditional PSTN networks.

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. The solution then processes captured packets, identifies and segregates calls based on signaling and traffic parameters.

The solution supports popular protocols like SIP, MEGACO, MGCP, H.323, SCCP, RANAP (UMTS IuCS), and GSM A.

Thanks to PDA, users can listen/record audio and video data of calls in real time; perform power, frequency, spectral, tones, digits, and video analysis with ease and precision; get an exact picture of Quality of Service (QoS) and the technical adherence of the system under test.

The detailed call statistics can provide details like packet loss, gap, jitter, delay, RTP performance statistics, R-factor & MOS scores, and unparalleled voice band statistics. “Sophisticated filters permit zooming and recording of specific calls of interest. All or filtered traffic can be recorded into a trace file,” Ramalingam added.
