July 8, 2009 — The leader supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks – GL Communications – announced today the release of enhanced PacketCheck™. CEO of the company – Mr. Vijay Kulkarni –  said it is a PC based Ethernet / IP BERT and Throughput test tool that is very easy to use. It also supports RTD (round trip delay), Loopback at all levels, including Ethernet frames and IP/UDP packets, and a simple to use GUI interface.

Mr. Kulkarni, further added, “PacketCheck™ allows monitoring of end to end performance such as total packets, packet loss, out of sequence packets, errorred packets, correct pattern frames, pattern sync status, and protocol statistics (Total IP packets, UDP Packets, IP/UDP Checksum errors etc ). It can operate on any of the three layers – Layer 2 (Data Link), Layer 3 (Network), and Layer 4 (Transport) of the OSI reference model”.

Important Enhancements Introduced:

Loopback Mode:
PacketCheck™ can now operate in Loopback mode in addition to its simultaneous Tx/Rx modes. PacketCheck™ can perform loopback at the Ethernet, IP and UDP levels. This powerful feature can prove extremely useful in diagnosing problems.

Calculation of Round Trip Delay (RTD):
PacketCheck™ now calculates the average Round Trip Delay. Round Trip Delay is the total time taken for a packet to travel to the remote end and back to the point of origin. Round Trip Delay can be calculated using 2 PacketCheck™ applications – one at the local end running in Tx_Rx (Transmit and Receive) mode and another at the remote end, running in Lopback mode. Round Trip Delay is reported in microseconds.

Command Line Interface:
PacketCheck™ can be operated through command line in addition to the simple to use GUI.

Other features include:

• Test Ethernet traffic of up to 500Mbps bandwidth
• Generates full duplex IP, UDP, or Ethernet frame traffic to transmit and/or receive traffic on any of the three layers (Data Link / Network / Transport) with on-demand bandwidth
• Bit-error-rate testing (BERT) on layer 2, layer 3, and layer 4 with detailed runtime statistics for both Tx and Rx
• Customizable 2 byte test patterns

Customizable protocol headers like MAC Source/Destination address, Length/Type field, IP Source/destination address, and UDP Source/Destination Port
