Clock Synchronization

The research area tackles the problem of synchronizing clocks in (spatially) distributed systems. Besides coordinated command execution and event sampling in sensor and automation networks also the real-time networks require synchronized clocks.

The strategic activities on clock synchronization are focused on high precision and fault tolerance. The clock synchronization group can look backward to various highly successful projects providing us with several years of experience in this field. Our expertise covers precise hardware design, software stacks, detailed simulation, as well as conceptual issues.

Current work in these fields continues investigations of wired clock synchronization, however in addition, more attention is devoted to areas where clock synchronization is an enabling technology, like positioning in wireless networks or network-based control systems. Please see our project page for more details.

To support the international community, the group is running a primary NTP server (stratum 1) available for public access. The server asynchronos.iiss.at provides NTPv4 synchronization capabilities and is member of the pool.ntp.org project.
If you want to use a time reference, please consider the instructions for using the pool or for direct access, please send a notification to ntp@fiss-oeaw.at.
