Press Release: GL Announces Enhanced PacketCheck™ w/ Stacked VLAN,
MPLS and XML Reports

Gaithersburg, Maryland, USA - December 15, 2012- GL Communications Inc. announced today the release of its enhanced PacketCheck™ - a Software Based Ethernet Tester.

Speaking to reporters, Mr. Vijay Kulkarni CEO of the company said, "GL's enhanced PacketCheck™ is a complete PC based Ethernet / IP test tool with BERT, Throughput, Delay, and Impairment testing functions. It is very easy to use as a general-purpose network performance analysis tool for 10Mbps, 100Mbps and 1Gbps LANs and WANs. Throughput up to 800 Mbps can be easily tested."

He explained new feature introduced, "PacketCheck™ applications' One-Way Delay - [within the same PC] is defined as the time a packet takes to travel from source to destination. It determines One-way Delay - [within the same PC] measurements between two NIC cards on a single PC with 2 instances of PacketCheck™ running, one on each NIC card in microsecond accuracy."

The feature Stacked VLAN allows different hosts to be a part of the same virtual LAN irrespective of their physical location. A group of hosts connected to the same switch can be partitioned into several VLANs, or a group of hosts connected to different switches can be combined into a single VLAN.

Stacked MPLS feature supports stacked MPLS layers up to 3 levels, customizable with headers like Label, CoS, TTL.

The application now supports True Bit error rate testing (BERT) on layer 1, layer 2, layer 2.5, layer 3, and layer 4 with various measurements - Bit Error Rate, Sync Loss Count, Bit Error Count, and more. Its capability to generate/respond to ARP requests making it easy to work with Routers. ARP packets are sent to determine the MAC address of the destination.

The application supports Common Statistics and Stream Specific Statistics. Common Statistics are stream independent at the NIC card level. These statistics are gathered before stream level statistics processing and these statistics helps user to check if the NIC card is receiving any traffic, and if receiving, if it is non-test traffic i.e. traffic not belonging to any of the configured streams.

Stream Specific Statistics provide per stream measurement of throughput, round trip delay (RTD), one way delay (OWD)- [within the same PC], total packets, packet loss, out of sequence frames, error frames, correct pattern frames, pattern sync status, bit error rate, sync loss count, error count etc.

Report generation feature now supports both XML and PDF formats. Reports include information such as the Statistics, Configuration Information, NIC card details, Stream Statistics, Common Statistics, VLAN, MPLS, etc with customizable headers and footers. Users can include their comments and logo in the report."

Mr. Kulkarni further added, "We hope our enhanced PacketCheck™ provides immense value in software based Ethernet testing and its user community."

Other features include:

  • Bit Error Rate and Performance Statistics
  • HDL File Playback
  • Traffic Generation Modes
  • Impairments Generation
  • PacketCheck™ Command Line Interface
