A GL Communication's Specialty— Stream Studies

Generating and analyzing as many as 16 user-defined Ethernet/IP streams of varying packet length is the focus of a new Multi-Stream Traffic Generator and Analyzer from GL Communications.

Modern day IP networks are becoming increasingly multi-stream in order to carry different kinds of traffic streams: data, voice, and video simultaneously. As IP networks are packet switched networks, they suffer from the inherent impairments introduced by packet switched networks—for example, Latency (Delay), Frame Loss, Jitter, Packet reordering. The challenge for modern day IP networks is to provide a good Quality of Service (QoS) for all the different kinds of streams despite the aforementioned impairments.

Additionally there is a need to measure key IP metrics of Throughput, Frame Loss, Delay and Jitter when the simulated streams are passed through the test network. There are also many enterprise-level applications designed to work on different networks such as enterprise networks, storage, cloud services, web services, ftp, audio/video streaming, and so on. Such applications also require testing with the real network conditions prior to live deployment. There are number of ways to do this. A basic method is to use Ethernet/IP multi stream traffic generation and analyzer devices." ​

According to Mr. Jagdish Vadalia, a Senior Product Manager for Product Development at GL Communications, GL's Multi-Stream Traffic Generator and Analyzer is a hardware based Ethernet tester capable of generating multi-stream Ethernet/IP traffic of varying packet length and also to analyze the looped back traffic and is especially useful for end-to-end testing of 1 Gbps and 10 Gbps WAN links.

Important features include...

  • Test tool with Ethernet traffic generation and analysis capabilities in one-box
  • Generate and analyze packets at 1GigE and 10GigE line rates. with zero packet loss
  • Dual Ports - with electrical ports support 10/100/1000 Mbps, optical ports support 1000 Mbps using SFP, and 10Gbps using SFP+s

The product is also available as tablet-inspired Touchscreen Handheld platform (PacketExpert™ 10G with a Tablet PC) that makes it highly suitable for field testing.
