PacketScan HD - Network Monitoring

Overview

PacketScan™ HD is a high density Ethernet monitoring appliance with specialized network interface cards, large storage capacity and protocol analysis software. Customers can choose the specific Ethernet data rate for the network interface cards including 4 x 1 GigE (PKV120), 2 x 10 GigE (PKV122), 2 x 40 GigE (PKV123) and 2 x 40 / 2 x 100 GigE (PKV124) variations. Almost all VoIP and Wireless protocols over IP transport layer can be captured and decoded for troubleshooting network problems.

PacketScan™ HD includes the PacketScan™ software which can provide in-depth real-time and post-process data investigation with its Packet Data Analysis (PDA) feature. The PDA view assists in comparing multiple RTP sessions. The PDA view displays call information in graphical format and tabular format.

PDA feature is available for SIP, H323, MEGACO, MGCP, GSMA, Skinny, and IuCS based calls. PacketScan™ HD can work with NetSurveyorWeb™, a central monitoring system for a comprehensive view of network performance. It features rich graphics, ladder diagrams and CDRs (Call Detail Records).  A web server is deployed in a central location along with an Oracle® database. Multiple PacketScan™ HD probes can be deployed in remote locations across the network to passively monitor VoIP traffic and send data to NetSurveyorWeb™.

GL's FastRecorder™ and PacketExtractor™ applications can capture and record packets on 1, 10, 25, 40, and 100 Gbps networks at wirespeed. The traffic is recorded from the FastRecorder™ application and extracted by the PacketExtractor™ which is then analyzed using PacketScan™ HD. The PacketScan™ HD can contain several terabytes of storage as requested by the customer. The PacketScan™ HD application supports decoding of eCPRI protocol. It also supports eCPRI protocol analysis tool which enables analysis and statistics of eCPRI message types such as IQ Data, Bit Sequence, Generic Data Transfer, Remote Memory Access, One-way Delay Measurement, Remote Reset, and Event Indication.

GL's IP Analytics™ tool along with FastRecorder™ and PacketExtractor™ application ensure Quality of Service (QoS) by analyzing IP-based data streams to meet performance standards. GL's IP Analytics™ offers detailed statistics for various parameters such as Layer 3, COS, Layer 4, IPv4/IPv6 Endpoints, UDP/TCP Endpoints, and conversations, enabling precise analysis of network performance. Capable to compute and visualize network metrics with millisecond precision, including Packet Count, Byte Count, Packets/sec, and Bits/sec, provides real-time insights crucial for optimizing network efficiency.

GL’s PacketScan™ 5G protocol analyzer supports monitoring of 5G networks. It captures, segregates, monitors, and collects statistics on all calls over N1N2, N4, N8, N10, N11, N12 and N13 interfaces of the 5G network. The 5G Protocol Analyzer is an optional module that can be acquired with PacketScan™.

GL’s TCP Analytics application analyzes TCP connections between both internal Local Area Network (LAN) and external Wide Area Network (WAN) computers including servers and clients. The application helps troubleshoot large bandwidth consumption, failed TCP sessions, packet loss, poor TCP throughput, rogue connections, security incidents including exfiltration of files, and more. TCP Analytics (PKV400) is an optional application with PacketScan™ HD - Network Monitoring Appliance.
