GL Communications (News - Alert) has launched its improved Packet Data Analysis tool for live monitoring of signaling and traffic over IP. Along with GL packet analyzers, the Packet Data Analysis (PDA) will provide a tool for VoIP traffic analysis.
Karthik Ramalingam, manager of product development for the company, said, “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), and GSM A,” Ramalingam added.
The PDA features capabilities that enable detailed capture, analysis, reporting and support for multiple protocols. Also users will get to listen to and record audio and video data of calls in real-time.
They can perform power, frequency, spectral, tones, digits, and video analysis in addition to providing a precise picture of QoS and technical adherence details of the system under test. Also the GL’s packet analyzers can capture IP packets over different transmission lines such as IP, T1, E1, T3, E3, and OC-3 STM-1 / OC-12 STM-4.
After which the PDA processes the captured packets, identifies and segregates calls based on signaling and traffic parameters. Users will benefit from the audio and video data of calls in real-time and can do video analysis with ease and precision.
The QOS (quality of service) details and the technical adherence of the system under test further enhance monitoring results. The adherence to the protocols specified by the standardizing authority can be verified.
In addition the detailed call statistics will cover packet loss, gap, jitter, delay, RTP performance statistics, R-factor and MOS scores along with unparalleled voice band statistics. The filters enable zooming and recording of specific calls of interest, and allow for the recording of all or filtered traffic into a trace file, said officials.
Other critical features include RTP packet statistics and call flow ladders; performance metrics; T.38 Fax over IP analysis; triggers and actions; CDR report generation and its performance as a probe in network monitoring systems.
In 2012 GL Communications introduced the digital central office switch simulator (DCOSS) and the GL Media Gateway (News - Alert) (MG) which supports traffic and signaling testing of VoIP and TDM networks. The DCOSS/Media Gateway combination provides user friendly bulk call generation, scripting, and other automated call generation and reception for various voice band traffic types including voice, fax, and modem traffic.
