Gaithersburg, Maryland, USA – February 16, 2015 - GL Communications Inc., announced today its latest product High-Density IP Traffic Analyzer referred to as PacketScan™ HD (High Density).  

Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for product development of the company said, “PacketScan™ is GL's standard framework for monitoring IP traffic. The HD version is a special purpose 1U hardware platform capable of detailed monitoring of high volume IP traffic (thousands of simultaneous calls).  Almost all VoIP and Wireless protocols such as SIP, MGCP, MEGACO, H.323, Skinny, LTE, Diameter, UMTS, GSM, and GPRS carried over SCTP transport layer (Link) can be captured, decoded, filtered, and analyzed.”

He added, “Capturing and analyzing high volume IP calls is increasingly important to Wireless Carriers, Internet Service Providers, and Equipment vendors to ensure that quality of experience does not degrade with call intensity, volume, or signaling protocol.

During pre- and post-deployment, load and stress testing are necessary to verify the stability of IP networks and network elements.  Since Quality of Service has always been a concern for carriers and service providers and they know that proactive monitoring of voice quality leads to happy customers. This requires an advanced network monitoring appliance which can capture and analyze high volume calls like GL’s PacketScan™ HD.”

Mr. Vadalia further explained, “The PacketScan™ HD supports simultaneous capture and processing of up to 5000 calls with duplex traffic at 1 Gbps rate (per appliance) and using a stack of multiple servers, a larger test system with more calls is achievable for enterprise to carrier grade testing.  

The PacketScan™ HD can act as a probe to monitor the network and send Call Detail Records (CDR) to a centralized database server.  GL’s NetSurveyorWeb™ can retrieve data from the database server and act as Central Monitoring System.  

The PacketScan™ HD appliance has the ability to capture and analyze calls in real-time and it can be used for traffic analysis of Digits, Tones, Voice, Video, and Fax.

The Packet Data Analysis (PDA) module within PacketScan™ HD provides in-depth real-time and post-process data investigation. Its Quality of Service parameters include E-model (G.107) based MOS/R-Factor scores, Packet Loss, Delay, and Jitter for voice calls.  Media Delivery Index is also available for Video.  It has complex filtering and search capabilities to record all or filtered traffic into a trace file and almost all industry standard codecs are supported.

The PacketScan™ HD provides Audio Capture and Playback, and Fax Call Capture and Decode (extracting fax images in TIFF format).  The Triggers and Actions feature of the application allows filtering calls based on call parameters and perform different actions (save call, record audio etc) on the saved calls.”
