GL Enhances Testing Solutions For Video Conferencing Quality

May 12, 2016 | Telepresence Options

Gaithersburg, Maryland, USA - May 09, 2016 - GL Communications Inc., announced today enhanced Video Quality Testing Solutions.

The other one is Bulk Video Call Simulation using GL's MAPS™ SIP and real-time Video Call Analysis using GL's PacketScan™ application."

He added, "GL's VQuad™ with VAC solution supports end-to-end Video Conference testing between any two VAC agents. Agents can be Linux, Windows or Android devices. In other words, test Video Conferencing between an Android phone and a Windows® PC. The VQuad™ with VAC solution is fully automated using VQuad™ scripting for testing a variety of scenarios with access to all video parameters such as Codec, Frame Rate, GOP Structure and Image Size.

GL's MAPS™ SIP provides a means for Bulk Video Call generation, simulating many Video Calls from a single MAPS™ SIP system. As part of this solution, GL's PacketScan™ can provide real-time Video Call Analysis of the video generated over the SIP call using a non-intrusive connection to the network."

Mr. Bichefsky further explained, "GL's VQuad™ solution provides an automated method to test Voice and Data from any mobile device. With the introduction of GL's VAC, Video Conference testing is added to the overall solution. Both Manual and Automated Video Conference tests can be generated between any two VAC Agents, including Android devices, Linux and Windows systems thus determining real-time performance of Video over a given network. The VAC solution is fully automated with QoS results for both Video and Audio provided along with several analytic metrics.

The Android devices (Smartphones and Tablets supported) and PCs (both Windows and Linux supported) become the agents or end points.

Testing can be performed between any two agents, Android to Android, Android to PC, or PC to PC. The user specifies the Test Plan configuration parameters such as Video Resolution, Codec, Frame Rate and GOP Structure along with test period (how long should the Video Conference last). Tests can be run directly from the Android device or using the VQuad™ interface. Both manual and automated tests are supported using flexible and versatile VQuad™ scripts.

GL's MAPS™ SIP with Video Calls option is a bulk SIP call generator which can simulate any interface within a SIP network including multiple User Agents. As a new enhancement, the RTP Video Traffic Generation capability is now added to GL's MAPS™ SIP Emulator. It can generate hundreds of concurrent video calls with codecs such as H.263, H.264 and VP8. Bulk video call generation capability helps in conducting load and performance tests on devices or network under test.

MAPS™ also supports transmission and detection of various RTP audio traffic entities for example: digits, voice file, single tone, dual tones and FAX.

PacketScan™ with Video QoS capability addresses customers need of Video Call Quality in IP networks. PacketScan™ can listen on a Mirror port of Switch to capture all IP traffic in the network. It can capture hundreds of video (H.263 and H.264) calls simultaneously and measures video quality metrics such as Media Delivery Index, Packet Loss, and Delay etc on each leg of the Video Call. PacketScan™ can also perform similar voice quality measurements such as MOS, R-Factor, Packet Loss, Jitter etc on the associated audio RTP sessions of the video call and hence gives the complete call quality report."
