GAITHERSBURG, Md., Nov. 16, 2023 (GLOBE NEWSWIRE) — GL Communications Inc., a global leader in telecom test and measurement solutions, spoke to the press about their PC-based Ethernet/IP testing tool, PacketCheck™. This cost-effective real-time testing solution is designed for Local Area Networks (LANs) and Wide Area Networks (WANs).

GL’s PacketCheck™ is a versatile, easy-to-use PC-based Ethernet and IP software program designed for testing and verifying LANs and WANs. It can generate and analyze hundreds of Ethernet/IP/UDP streams, all with user-defined MAC and IP addresses, from a single PC.

“PacketCheck™ provides comprehensive Ethernet testing, covering all protocol layers, from standard Ethernet frames to stacked VLAN, MPLS and IP packets with UDP data. It uses the PC’s Network Interface Card (NIC) to send and receive Ethernet and IP packets on LANs and WANs,” said Vijay Kulkarni, CEO of GL Communications.

The application offers additional features such as simulating traffic by sending pre-recorded files and generating traffic with an Interframe Gap (IFG) precision of up to 5 milliseconds. It includes Bit Error Rate (BER) testing capabilities using PRBS patterns or custom-defined test patterns.

PacketCheck™ works with Multi-link Frame Relay (MFR) and provides a traffic function called MFR-IP-PacketCheck™ for generating IP traffic over Frame Relay (FR) links. It supports the generation and processing of multiple IP traffic flows over different virtual channels within the FR links. Each IP traffic flow can be customized to customize the IP packets with specific headers to emulate different modes such as Bridge and Route.

Most important features

  • Test Ethernet/IP/UDP traffic with a bandwidth of up to 500 Mbps

  • Generate full-duplex traffic on each of the four layers (Layer1, Layer2 (Ethernet) with stacked VLAN/MPLS, Layer3 (IPv4), Layer4 (UDP)) with on-demand bandwidth

  • Measure bit errors, synchronize loss counts, throughput and more

  • Create multiple full-duplex streams with different frame size, rate, header, PRBS pattern, etc. Measure throughput, packet loss and bit errors independently for each stream

  • Supports frame sizes ranging from 22 bytes to 1518 bytes

  • Measure one-way delay through an isolated device (between two NICs on the same PC) or round-trip delay (with external loopback)

  • Record traffic per stream to a Wireshark file (NGPCAP or NTAR format) or HDL file (GL Proprietary format). Separate files for each stream

  • Playback of a Wireshark file (NGPCAP or NTAR format) or HDL file (GL native format), with adjustable traffic rate

  • Start or stop each stream independently at runtime

  • Log unidentified network traffic in a PCAP or HDL file format

  • Independently define each stream to operate as Layer 2 (Ethernet) or Layer 3 (IP) or Layer 4 (UDP)

  • Supports Jumbo frames

  • The transmission speed can be configured to operate in Burst mode or IFG mode

  • PRBS Pattern generation/verification of various patterns such as QRSS, 26-1, 29-1, 211-1, 215-1, 220-1, 223-1

  • Generate various runtime constraints – byte insertion/deletion and byte-level constraints

  • Generate/respond to Address Resolution Protocol requests, making it easy to work with routers

  • Generate reports in XML or PDF formats

Applications

  • Create multiple traffic flows for network testing at Layer 2, 3, or 4

  • Test for bit errors, packet loss, throughput, etc. over a network path

  • Determine the round-trip delay between two endpoints with microsecond accuracy

  • Control one-way delay through an isolated device such as a switch or router

  • Record test traffic in binary and/or PCAPNG or NTAR file format

  • Play PCAPNG files for test traffic generation. Either recorded from test BERT traffic or recorded traffic of interest

  • Include non-test packets in a PCAPNG file. that is, non-BERT traffic-related packets
