Gaithersburg, Maryland, USA – August 03, 2015 - GL Communications Inc., announced today its enhanced PC based Ethernet Tester referred to as PacketCheck™.  Now, it is enhanced to support GTP Traffic Simulation. GTP, or GPRS Tunnelling Protocol are the methods for sending IP traffic in Wireless Networks such as GSM, UMTS, and LTE.

Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for product development of the company said, ‘GL's 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 test/analysis tool for 10Mbps, 100Mbps and 1Gbps LANs and WANs. Throughput up to 800 Mbps can be easily tested.

PacketCheck™ also measures end-to-end performance such as Bit Error Rate, Total Packets, Packet Loss, Out of Sequence Packets, and Error Packets. Other important features include transmission of pre-recorded file traffic, GTP traffic simulation, Bursty and Fixed IFG (Inter Frame Gap) traffic generation modes, Delay measurements including One Way Delay - [within the same PC] and Round Trip Delay, Impairment Generation, and BER Testing capability with provision to generate PRBS patterns or user-defined test patterns.”

He explained, “Using the File Playback feature within PacketCheck™, the packet data can be carried as pre-recorded traffic files (GL's proprietary Ethernet traffic capture format *.HDL files) to destination points and the same can be verified at the receiving end, which can also be a PacketCheck™. This feature can be used with GL’s Mobile IP Core traffic module (requires Additional Licenses) to simulate GTP traffic over UMTS or LTE network.

Generally, in an Evolved Packet Core (EPC) network, the two types of data pipes can be found - Default Bearer (with non-guaranteed QOS) and Dedicated Bearer (with assured guaranteed QOS). To verify such bearer allocation bandwidth at the end points, the PacketCheck™ can be used with GL’s MAPS™ UMTS / LTE Simulators which allows to encapsulate the generated packet data within GTP headers and transmit through the gateway points such as SGSN & GGSN, or SGW & PGW. The packet data traffic generated at one end is received at the other end can be verified with various statistics such as packet loss, lost frames, bit error count, Tx Rx frames count and other traffic parameters.”

Mr. Vadalia further added, “The other important features of the application are: One way Delay measurement, Round-trip delay measurement (RTD) between two end points, Stacked VLAN that allows different hosts to be a part of the same virtual LAN irrespective of their physical location, Stacked MPLS, BERT, ARP packets, Common statistics, and Report generation and more.”
