GL's enhanced PacketCheck™ is a PC based Ethernet / IP BERT and throughput test tool that is comprehensive and very easy to use as a general purpose network performance analysis tool for 10Mbps, 100Mbps and 1Gbps LANs and WANs. The application truly takes confusion out of Ethernet and IP testing at all protocol layers - from raw Ethernet frames to IP/UDP packets
Gaithersburg, Maryland, USA (Vocus) May 12, 2010
GL Communications Inc. announced today the release of enhanced PacketCheck™ - a PC based Ethernet / IP BERT and throughput test tool. Speaking to media, Mr. Jagdish Vadalia, Senior Manager of Product Development said, “GL's enhanced PacketCheck™ is a PC based Ethernet / IP BERT and throughput test tool that is comprehensive and very easy to use as a general purpose network performance analysis tool for 10Mbps, 100Mbps and 1Gbps LANs and WANs. The application truly takes confusion out of Ethernet and IP testing at all protocol layers - from raw Ethernet frames to IP/UDP packets”. He added, “The application now has features like transmission of prerecorded file traffic. This is a new traffic generation mode that can duplicate packet traffic as it occurred at a particular Ethernet interface. A new Command Line Interface (CLI) has also been added that supports all the GUI functionalities of PacketCheck™. This will permit easy scripting and automation. Also, a powerful Report Generation feature allows easy generation of user friendly reports”.
Mr. Vadalia further added, “PacketCheck™ has wide ranging applications - including maximum IP bandwidth measurement between two points, Round Trip Delay (RTD) between two IP address locations with microsecond accuracy, Locating LAN Data Switch packet dropping and errors occurrence, detection of traffic overlaod, testing network behavior with real world traffic like IPTV, VoIP and more. PacketCheck™ makes use of the PC's network interface card (NIC) to transmit and receive Ethernet or IP packets over the network.Throughputs up to 800 Mbps can be easily tested. The application generates multi stream Ethernet/IP/UDP traffic and measures end to end performance such as Byte Error Rate, Total Packets, Packet loss, Out of Sequence Packets, and Errorred Packets”.
Important Enhancements Introduced:
•HDL File Playback
PacketCheck™ can now transmit HDL file traffic. An HDL file is GL's Ethernet traffic capture format. In addition to the captured packet, HDL file contains additional information like the captured timestamp. PacketCheck™ can retransmit traffic according to the stored timestamp or the user can provide his own Inter Frame Gap. Also, the user is able to replace the stored MAC/IP/UDP header parameters with configured parameters. HDL File Playback gives PacketCheck™ the ability to simulate real world traffic like IPTV, VoIP, and data.
•Traffic Generation Modes
A new traffic generation mode has been introduced into PacketCheck™ – the IFG (Inter Frame Gap) mode. Previous versions had only the Burst Mode, where traffic generated was bursty and the emphasis was on maintainence of the configured bandwidth. In the new IFG mode, the emphasis is on maintaining the Inter Frame Gap between successive packet transmissions. User can configure the IFG value.
•PacketCheck™ Command Line Interface
A new Command Line Interface (CLI) has been added to PacketCheck™. All the functionalities of PacketCheck™ can be accessed via commands, instead of the GUI. The CLI can be accessed through GL’s proprietary WCS (Windows Client Server) architecture, thereby allowing remote execution of commands.
PacketCheck™ now has the capability to generate report at the end of the test. Report includes information such as the Statistics, Configuration Information, NIC card details etc. Report can be generated in various formats like Portable Document Format (PDF), Rich Text Format (RTF), Document Format (doc), Excel Sheet Format (xls), HTML Format with customizable headers and footers. Users can include their comments and logo in the report.
Other features include:
•Test Ethernet traffic of up to 800Mbps 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
•Multistream Traffic generation with independent configuration parameters and measurements for each stream
•PRBS Pattern Generation/Verfication of various patterns like QRSS, 2^6-1, 2^9-1, 2^11-1, 2^15-1, 2^20-1, and 2^23-1
•Measures Byte Error Rate, Declares Sync/Sync Loss and Monitors Performance Statistics like Throughput, Packet loss, Out of order packets, Calculates Round Trip delay
•Run Time Impairments generation of various impairments like Insert/Delete Bytes, Change Bytes etc.
•Jumbo frames are supported, in addition to all normal frame sizes from 64 bytes to 1518 bytes
•Customizable protocol headers like MAC Source/Destination address, Length/Type field, IP Source/destination address, and UDP Source/Destination Port
About GL Communications Inc.

Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, etc.), and with capacities up to thousands of channels.
GL’s VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.
GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.
