Deployment of mission critical networked applications like Videoover-
IP, remote collaboration systems and control via Internet Protocol
raises requirements on Quality of Service of local and global 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 active network performance
measurement, analysis and monitoring 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
• support of diverse Linux/Unix systems
• CLI- and WebGUI-based control
• detailed measurement reports, export to flat files for further pro
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.
