The Ethernet network is a good control interface for distributed measurement systems. The de facto standard in HEP experiments is IPbus. The experiences from using IPbus resulted in the proposal of a new Ethernet-based control interface optimized for quick parallel configuration of multiple systems.
The system ensures reliable delivery of control commands and responses.
The minimalistic local controller minimizes the negative effects of the Ethernet round-trip latency. Usage of layer 2 Ethernet frames minimizes the FPGA resource consumption. Implementation of the software part in Linux kernel space reduces dependency on specific software packages and libraries.
How to cite
Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
