GL Communications (News - Alert) Inc., a company that provides PC-based test, analysis and simulation products and consulting services, recently announced that it has added new features to its Packet and VoIP Network Monitoring System, making the solution more capable of monitoring packet flows in real-time within a VoIP network.

GL’s Packet and VoIP Network Monitoring System provides visualization, capture, storage, and convenient features like portability, remotability, and scripting. The solution is widely used for conformance testing, automated stress/load testing, performance testing, remote accessibility, centralized Web-based control and analysis, fault testing and analysis, and customized testing.

 “The Packet and VoIP network Monitoring System uses GL's Packet probe called "PacketScan” and/ or Voice band Analyzer, PacketProbe to monitor packet flows in real-time within a VoIP network,” said Jagdish Vadalia, senior manager for product development at GL Communications. “All major VoIP protocols are supported including SIP, H.323, Megaco, SIGTRAN, RTP, and MGCP. A central database stores the real-time and historic data. The system also facilitates various views using a Web interface known as ‘PacketScanWeb’.”

He explained, “PacketScan probe a feature-robust Windows based software tool that captures and monitors live IP traffic in a non-intrusive fashion and forwards call detail records (CDRs) as well as statistics to a central database. PacketScan performs detailed analysis of voice band streams gathering QoS statistics such as MOS (Mean Opinion Score), total packet count, reordered, duplicate and missing packet counts, packet gap, jitter, and delay. In the VoIP world, it can monitor and measure SIP, H323, Megaco, MGCP, T.38 and video calls. In addition to quality metrics, PacketScan also captures signaling information and sends that to the PacketScanWeb database as well.

GL Communications recently unveiled improved Ethernet LAN and WAN Simulation Equipment. IPNetSim models are presented at diverging capacities, ranging from 100 Mbps copper or SFP, 1 Gbps 8 Gbps Copper or SFP, or a maximum of 40 Gbps with Dual Rate 1 Gbps/10 Gbps SFP+ interfaces. The IPN400, an IPNetSim with 1Gbps configuration, delivers 8 Gigabit Ethernet port along with a Maximum Aggregate Throughput of 8. The IPN400 is perfect for multi-link configurations and multi-user labs. Copper and modular fiber/copper Gigabit Ethernet interfaces are available for the tiny 1U-sized appliance.
