PacketScan™ HD - Network Monitoring Appliance

PacketScan™ HD Software Ver 7.1.13 (64-bit Only) is Available! | Download Now!


Capturing and analyzing high volume calls is increasingly important to Wireless Carriers, Internet Service Providers, and Equipment vendors to ensure that quality of experience does not degrade with call intensity, volume, or protocol. Load and stress testing are important to verify stability of IP network and network elements pre- and post-deployment. This requires an advanced network monitoring appliance which can capture and analyze high volume calls with traffic.

GL’s PacketScan™ HD is a high density multi-protocol 2U rack mounted Network Monitoring Appliance w/ 4x1GigE (PKV120)  and w/2x10GigE  (PKV122) (Includes PKV100 online for temporary audio codec support) network interface cards that can capture and process high volumes of communication protocols over IP and Wireless networks.

PacketScan™ HD supports simultaneous capture and processing of high volume of simultaneous calls with bidirectional RTP traffic from 1 Gbps to 10 Gbps rate. Almost all VoIP and Wireless protocols over IP transport layer can be captured and decoded for troubleshooting network problems.

PacketScan™ provides in-depth real-time and post-process data investigation with its Packet Data Analysis (PDA) feature. The PDA view assists in any comparisons that are to be made between the two RTP sessions. Packet Data Analysis (PDA) view displays call information in graphical format (Traffic Analyzer Call Quality Matrix- Summary View) as well as in tabular format (RTP Diagnostic - Detail View).

For more details visit Packet Data Analysis.

*Currently PDA feature is available only for SIP, H323, MEGACO, MGCP, GSMA, Skinny, and IuCS based calls. The PDA support for other protocols will be coming soon.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. A number of GL’s PacketScan™ HD probes and/or, PacketProbes™ are deployed in remote locations across the network to passively monitor VoIP traffic.

For more capacity, PacketScan™ FB (Near-Realtime File Based Packet Processing Tool) will be offered in near future.

  • VLAN 0, 1, 2: Filters frames based on Tag protocol ID, User Priority, CFI, and VLAN ID.
  • IPV4: Frames can be filtered based on Source IP Address, Destination IP Address, Protocol Type, Header Length, Differentiated Services, Ds_ECN, DS_CodePoint, Total Length, Check Sum Error, IP Datagram ID, Fragmentation Offset, Flag_DontFragment and Flag_MoreFragments.
  • IPv6: Frames can be filtered based on Source IP address, Destination IP address, Next Header, and Payload Length.
  • ARP: Frames can be filtered based on Sender MAC Address, Target MAC Address, Sender IP Address, Target IP Address and Option Code.
  • TCP: In TCP layer Frames, can be filtered based on source port, destination port and check sum error.
  • UDP: In UDP layer Frames can be filtered based on source port, destination port, check sum error, UDP length and payload. For more details, refer to
  • SIP and RTP: SIP and RTP packets can also be filtered based on source port or destination port.
