GL Communications' New PacketScan HD Provides Better Analysis of IP Traffic


February 19, 2015

GL Communications announced recently that it had released a new and improved version of its PacketScan IP analyzer. The PacketScan HD makes it possible to monitor a greater volume in IP traffic and with greater detail.

Gaithersburg, Md.-based GL Communications, Inc. (GL) provides a variety of testing equipment for the telecom industry. The company lists several U.S. federal government agencies and departments, telecoms, international governments, universities and network product companies as customers.

The arrival of PacketScan HD comes in response to greater demand for content over the Internet. Cisco’s VNI Forecast predicts that, “In 2018, the gigabyte equivalent of all movies ever made will cross global IP networks every 3 minutes.” Between 2013 and 2018, the same forecast predicts a nearly three-fold increase in global IP traffic.

According to GL, the PacketScan HD has the capacity to process 5000 simultaneous calls with bidirectional RTP traffic at 1 Gbps per appliance. The single rack unit device works with PCs running on Windows with a sound card and the GL HD interface card installed. It is not limited to monitoring voice data as it can also monitor fax data, video, tones and digits.

Traffic information can be saved to a trace file for future analysis. Traces can be configured to capture all information or filtered to capture only traffic that meets certain criteria.

The PacketScan HD will serve an important behind-the-scenes role for network admins. Network traffic will only continue to increase in volume and speed, and being able to analyze it in detail will be critical to solving various problems that can come up. Dropped calls, incomplete calls, delays and poor quality of calls can easily be tracked.

The world is becoming more dependent on the Internet, and with the proliferation of M2M and IoT use, this dependence will be even greater. The expectation will be that the Internet becomes ‘automatic’. We will demand that we get whatever content when we want it and have less tolerance for delays. Tools like PacketScan HD will therefore be critical in identifying problems quickly and keeping these delays to a minimum.

Day 2, Cisco Live! 2017

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.
