Next-Generation Ethernet and VoIP Protocol Analysis Solution

GL is excited to introduce the latest edition of our Newsletter, showcasing our advanced network analysis tool - PacketScan™ HD. This network appliance captures and analyzes high-speed Ethernet traffic up to 100 Gbps. With PacketScan™ HD, network engineers and cyber security professionals can accurately assess their network performance, identify bottlenecks, troubleshoot infrastructure and applications, and investigate security incidents.

PacketScan™ HD


GL’s PacketScan™ HD is an Ethernet monitoring device designed for high-density network analysis. Equipped with specialized network interface cards, ample storage capacity, and advanced protocol analysis software, it captures and decodes all Voice over IP (VoIP) and Wireless protocols over IP. This capability is invaluable for troubleshooting network issues and investigating security incidents. Additionally, users can conduct lossless packet capture, analyze high-speed networks, and manage high-volume simultaneous calls with bidirectional RTP traffic seamlessly.

PacketScan™ HD includes the PacketScan™ software, a comprehensive tool for capturing, categorizing, monitoring, and collecting statistics on various IP calls. This software excels at decoding VoIP and wireless protocols, providing detailed Quality of Service (QoS) statistics for voice calls. Moreover, it can seamlessly transfer captured data to GL's centralized database and dashboard, known as NetSurveyorWeb™. This platform offers a user-friendly web browser interface, facilitating remote access and easy navigation for users.

5G Protocol Analyzer

GL's PacketScan™ HD 5G Protocol Analyzer is capable of monitoring 5G networks effectively. It captures, decodes, and gathers statistics across various interfaces such as N1N2, N4, N8, N10, N11, N12, and N13 within the 5G network infrastructure. This analyzer is an optional module that can be added to PacketScan™ HD by obtaining additional licensing, enhancing its capabilities for 5G network analysis.

Enhanced Network Monitoring with FastRecorder™ and PacketExtractor™ Application

PacketScan™ HD is compatible with the FastRecorder™ and PacketExtractor™ applications, providing wirespeed IP traffic filtering and recording capabilities of up to 320 Gbps directly onto disk. This feature allows for offline filtering, extraction, and analysis of captured data. These applications support a range of Ethernet interfaces, including 4 x 1 Gbps, 2 or 4 x 1/10 Gbps, 2 x 25/40/100 Gbps, or 8 x 10 Gbps Ethernet interfaces, ensuring versatility in network monitoring and analysis.

Examining Quality of Service with GL's IP Analytics™

GL's IP Analytics™ tool, in conjunction with the FastRecorder™ and PacketExtractor™ application, scrutinizes IP-based data streams to against performance benchmarks. This tool provides comprehensive statistics for parameters like Layer 3, Class of Service, Layer 4, IPv4/IPv6 Endpoints, UDP/TCP Endpoints, and conversations, facilitating accurate network performance analysis. With the ability to calculate and present network metrics with millisecond precision, including Packet Count, Byte Count, Packets/sec, and Bits/sec, it offers real-time insights essential for optimizing network efficiency.

TCP Analytics for TCP Connection Analysis

GL's TCP Analytics application examines TCP connections across internal Local Area Network and external Wide Area Network computers, encompassing servers and clients. This tool aids in diagnosing issues like excessive bandwidth usage, unsuccessful TCP sessions, packet loss, subpar TCP throughput, rogue connections, security incidents including exfiltration of files, and other related issues. TCP Analytics is an optional feature available with the PacketScan™ HD - Network Monitoring Appliance.

PacketScan™ HD Hardware Platforms

GL’s PacketScan™ HD is available in portable and rack-mount form-factors with smart network interface cards having different Ethernet rates such as 4 x 1 GigE, 2 x 10 GigE, 2 x 40 GigE and 2 x 40 / 2 x 100 GigE variations to capture packets at high speeds.
