PacketScanPX™ - Wirespeed filter, capture and analysis

Overview

PacketScanPX™ is a unified application that combines the wirespeed hardware capture capabilities of PacketExpert™ with the deep protocol analysis features of PacketScan™ to overcome the limitations of software-only packet capture at capture rates up to 3 Gbps. While PacketScan™ provides powerful decoding, KPI visualization, call-flow analysis, and troubleshooting across VoIP, IMS, LTE, 5G, and IP networks, its capture performance depends on the PC’s onboard NIC. PacketExpert™ complements this by enabling hardware-assisted wirespeed capture, precise timestamping, and selective traffic filtering up to 3 Gbps. By integrating both into PacketScanPX™, users can perform real-time selective capture and deep protocol analysis within a single workflow, reducing packet loss, improving timestamp accuracy, minimizing storage requirements through hardware filtering, and simplifying troubleshooting in lab and field network monitoring environments.

PacketExpert™ Hardware is a versatile Ethernet testing tool, with various testing functionalities, one of which is the wirespeed capture functionality. This is a quad port unit, of which 2 are 10 Gbps SFP+ based ports, and other 2 are 10/100/1000 Mbps Electrical/Optical ports. For some of the functionalities, the 10 Gbps SFP+ ports can be downshifted to support 1Gbps ports, thus offering 4 Electrical / 4 Optical 1 Gbps ports for ethernet testing. SFP ports can be used as RJ45 ports by plugging in the appropriate Electrical (Copper) SFPs. The same 10Gbps ports can also be converted to 2.5Gbps Electrical interface using appropriate SFPs.

GL's PacketScanPX™ - an All-IP Network Monitoring software offers powerful features to capture and monitor live signaling and traffic over IP (version 4 and 6). The application can capture, segregate, monitor and collect statistics of all types of calls over IP. Almost all VoIP and Wireless protocols and traffic types over IP network, as listed here, can be captured, and decoded for troubleshooting network problems.

• Supports decoding of almost all industry standard signaling protocols – See Protocol List for more details
• SIP, SIP-I, SIP-T, H.323, MEGACO, MGCP, Skinny (SCCP)
• IMS-SIP, Diameter
• LTE (requires additional licensing)
• SIGTRAN – SS7, ISDN (requires additional licensing)
• GSM A and Abis over IP (requires additional licensing)
• GPRS Gb and Gn over IP (requires additional licensing)
• UMTS IuCs and IuPs over IP (requires additional licensing)
• T.38 and Video calls
• ED-137/ED-138  (requires additional licensing)

PacketScanPX™ allows to set hardware level filters for capture flexibility. Up to 16 hardware level filters can be defined per port. Filters can be set for various header fields like Source/Destination MAC/IP addresses, UDP/TCP ports, 802.1Q VLAN Id/Priority fields, IP ToS/DSCP fields, Frame size etc. and also a user defined raw hex filter of 120 byte length, with an offset (to filter 120 bytes of raw hex data anywhere within the packet). Further, the individual filters can be combined into groups and the groups can be further combined into super groups for additional flexibility.
