Thema:LTest - High-precision IP-Network Performance Test Analysis

Deployment of mission critical networked applications like Video-over-IP, remote collaboration systems and control via Internet Protocol raises requirements on Quality of Service of data networks significantly. So, monitoring and active metering of the network performance becomes key task for network administrators, network designers and researchers.

LTest enables network administrators doing this with

  • soft-RT capability with up to 1 µs accuracy
  • up to 10 Gbit/s measurement throughput
  • high-precise and fine-grain analysis of gathered data
  • IPv4 and IPv6 capability
  • CLI- and WebGUI-based control
  • detailed measurement reports, export to flat files for further processing

Even with millions of probes, singularities on one-way delays and inter-packet times can be analyzed. Furthermore, packet loss patterns, delay and jitter trends as well as behavior of particular device queues can be investigated. Based on such measurement results, bottlenecks in IP infrastructures can be identified and measures for performance optimization can be elaborated.

LTest is a versatile active network probing tool for each network administrator, network system designers and network researchers. It is already used by diverse research teams for protocol development and IP infrastructure optimization. With patent pending method of short-term time synchronization in an order of 10-8 s, LTest enables researchers doing high-accurate network protocols optimization.

Besides the licensing of the software, customizing and adoption to existing network analysis systems are offered.
