The internet onboard of ships is very slow and uncomfortable. This is caused by the high latency of the used satellite networks. Most internet connections are based on connection-oriented protocols, like TCP/IP, which require positive acknowledgments for each data packet sent. To fasten the data transfer, the use of a connectionless protocol without positive acknowledgments would solve the latency problem. But such a protocol, like UDP, is not secure enough nor supported by most of the web servers. The aim of the present development is therefore to provide a fast and secure data transmission in networks having a high latency. This object is solved by a connectionless data protocol having a parallel information channel between the client and a server which is independent of transmission of the payload. Said information channel is e.g. used for negative acknowledgements for lost packets or connection relevant information like the available bandwidth. Furthermore, to avoid lots of time consuming singular connections for each object of a webpage, a proxy server may be used that collects all relevant data of an external web server, renders the data in a headless browser, and only sends the completely rendered web-page to the client in one data stream.
