Paper Abstract

The large amount of data collected by the automatic astronomical cameras has to be transferred to the fast computers in a reliable way. The method chosen should ensure data streaming in both directions but in nonsymmetrical way. The Ethernet interface is very good choice because of its popularity and proven performance. However it requires TCP/IP stack implementation in devices like cameras for full compliance with existing network and operating systems. This paper describes NUDP protocol, which was made as supplement to standard UDP protocol and can be used as a simple-network protocol. The NUDP does not need TCP protocol implementation and makes it possible to run the Ethernet network with simple devices based on microcontroller and/or FPGA chips. The data transmission idea was created especially for the "Pi of the Sky" project.
