This is VILLASnode, a gateway for processing and forwardning simulation data between real-time simulators.
VILLASnode is a client/server application to connect simulation equipment and software such as:

 - OPAL-RT RT-LAB,
 - RTDS GTFPGA cards,
 - RTDS GTWIF cards,
 - Simulink,
 - LabView,
 - and FPGA models

by using protcols such as:

 - IEEE 802.2 Ethernet / IP / UDP,
 - ZeroMQ,
 - nanomsg,
 - WebSockets
 - Shared Memory
 - Files

Planned:

 - IEC 61850-9-2 Sampled Values,
 - IEC 61850-8-1 GOOSE,
 - AMQP

It's designed with a focus on very low latency to achieve almost realtime exchange of simulation data.
VILLASnode is used in distributed- and co-simulation scenarios and developed for the field of power grid simulation at the EON Energy Research Center in Aachen, Germany.
