PacketCheck

Paid Windows

What PacketCheck is

PacketCheck is a paid Windows desktop tool for generating and analyzing multi-stream Ethernet and IP traffic. It performs bit-error-rate, throughput, delay, and impairment testing across Layer 1, Ethernet Layer 2, stacked VLAN/MPLS Layer 2.5, IPv4 Layer 3, and UDP, TCP, and ICMP Layer 4 traffic. Throughput and impairment testing are supported up to 500 Mbps across 10 Mbps, 100 Mbps, and 1 Gbps LANs and WANs. Users configure stream addresses, VLAN/MPLS headers, frame sizes, rates, and protocol parameters. The software measures packet loss, out-of-sequence and errored packets, throughput, and one-way or round-trip delay. It records and replays PCAP, PCAPNG, NTAR, and GL proprietary HDL files, introduces byte or bit errors, and creates PDF or XML reports. PacketCheck runs on a standard Windows PC with a network interface card. Licenses are node-locked or floating, with pricing on request.

Who it suits

PacketCheck suits network engineers and test teams that need configurable Ethernet/IP traffic generation, impairment testing, measurements, and reports on Windows.

What it does well

Supports multiple protocol layers
Traffic testing up to 500 Mbps
PCAP and PCAPNG capture playback
PDF and XML reporting
Node-locked or floating licenses

What to know first

Windows desktop only
Pricing available on request
Higher-rate accuracy recommends Intel Ethernet hardware
Some GTP simulation integrations need extra licenses

Limits

Throughput and impairment testing are supported up to 500 Mbps. Correct one-way delay measurement requires one PC with two NICs running PacketCheck on each; round-trip delay requires the remote device to use loopback.

Getting started

Open the PacketCheck product website
Obtain a node-locked or floating license
Use a standard Windows PC with a network interface card
Connect the network interfaces and configure traffic streams
Run measurements or impairment tests
Generate PDF or XML reports

Verdict

PacketCheck provides broad Ethernet/IP test configuration, measurements, impairment controls, and report output for Windows users. Its license pricing is not published, and some advanced accuracy or simulator scenarios have additional requirements.

Questions

Which operating system does PacketCheck support?

PacketCheck is a Windows desktop product.

What hardware is required?

A standard Windows PC and network interface card are sufficient. GL recommends a high-performance Intel Ethernet adapter for better accuracy and stability at higher rates.

What license types are available?

The product is offered with node-locked or floating licenses.

What traffic can PacketCheck test?

It tests Ethernet, IPv4, UDP, TCP, ICMP, VLAN, MPLS, and GTP-related traffic across the listed protocol layers.

Can it simulate GTP traffic?

GL describes using PacketCheck with its MAPS UMTS/LTE simulators for GTP traffic simulation; additional licenses are required.
