Diese Arbeit beschäftigt sich mit historischen Delay-Tolerant Networking Systemen, die vor der Verbreitung des Internets existierten. Neben UUCP und dem Usenet werden auch heute kaum noch wahrnehmbare Netze, wie das FidoNet und das Z-Netz, beleuchtet. Neben den technischen Details der damaligen Protokolle werden besonders die Netzstrukturen und die Verbreitung betrachtet. Für jedes der behandelten Netze bzw. ihre Protokolle wird erklärt, warum diese heute nicht oder kaum mehr verfügbar sind.

Keywords: DTN, Delay Tolerant Networking, Unix to Unix Copy, UUCP, FidoNet, Zconnect, UseNet
